Bicycle Cadence sensor based on audio recording - Design, Prototyping, UI, Graphics

The idea is to create a very low cost app and sensor to monitor the cadence of a bicycle. Since most of app can find the speed through GPS, I need one that count how many RPM I'm doing.
1. I don't know how to program android app or even which language I should use
2. The idea consists on adapting one magnet on the crank and the other on the bike frame near to the crank course
3. When the magnet on the crank goes through the other one on the bike frame it should create a small current
4. This magnet would be wired to the android based cellphone (perhaps a Galaxy Nexus) on the audio port
5. The small current should generate a sound
6. This sound should be intepreted as one full cycle
7. The software must count and store how many cycles per minute I'm doing
How could one do this?

distance / circumference = rotations
It sounds like you already have distance traveled from the GPS record.
If you can measure your tires, πd (or 2πr) will give you the circumference, and distance/circumference will give you number of rotations, no additional hardware required.

As I understand marcoskp, he want to monitor cadence ( rate per minute of crank not wheel).
In this case you should have information of current transfer also if you want to use speed from GPS to calculate.
But you can have situation when crank is stable and you are still moving.
So external sensor is necessary.
Using audio port is very good and easy solution, but cause of wireing, have you consider BT sensor?
It should work same but instead connecting it to audio port you create switchable transistor and count full circles (simple counter) as a rising slope. And those information will be sent via Bluetooth (counter value).
It will be only little more expensive ( BT module here is only one with real cost, and it's quite cheap ) but much easier to mount.

Thanks saffron82. More than that, bikes works with differents gear ratio. Some are fixed, but today people uses 21 to 30 speeds (or 20 if you are using sram's 2x10). So cadence may change a lot if you are using a bigger or smaller ratio. The idea behind audio port is also to consume less energy. But I may be wrong. Perhaps bt consumes less energy.

Compas

Now i love my desire... Its fantastic but it isnt without some issues...
One ive noticed that could be a problem esp when your working with reality overlay apps...
The compass doesn’t seem to work that well...
Its slow to respond to movement and even when it does move its horridly inaccurate. north seems to have a room for error of 60-90 degrees.
Has anyone else noticed this? Is it the same for most digital compasses? or do i have a faulty module?
Hi Nutsy,
I've also noticed these issues with the compass in the Desire. I've worked with magnetic compass chips before and I think it's all to blame on the way these compasses work:
To sense the earth's magnetic field they use a two- or three axis magnetometer. Although it's a very accurate way to sense the earth's weak magnetic field, it's also very sensitive to any other magnetic field. That means that the presence of ferromagnetic materials (like iron) or electrical currents in the vicinity might really screw up your compass reading.
So electrical wires, iron piping, laundry machines (almost anything that you would find indoors that runs on electricity or contains iron), will interfere with your compass.
a good alternative would be to use a gyroscopic compass like they do on submarines, but I don't think these fairly expensive devices aren't used in mobile equipment yet. So the only thing to do is to stay away from anything that might interfere.
The slow response to movement might be caused by internal filtering. These analog sensors produce quite an amount of measurement noise. In order to cancel this, they probably use some sort of filtering algorithm like this one:
step 1 -> Take a new sensor reading.
step 2 -> Add it to a buffer that contains the last 25 readings.
step 3 -> Calculate the mean value of all measurements in this buffer. This will be the compass heading that is sent to Android OS or your application.
step 4 -> Repeat this cycle every 25 milliseconds.
Hope this answers your questions. Of course if you compass readings never make any sense under any circumstances, the thing might just be broken...
Friendly regards,
Joost
Ps.
There's an App in the market called "Metal detector" that actually uses the interference "problem" with the compass to detect ferromagnetic metals.
Wow Thanks for the really detailed reply...
Im glad its not just me then... Didnt really want to RMA it over a dodgy compass unit.
And thanks for letting me know about that app... sounds usful... I guess it could be used to detect wireing in plaster as well?
You're welcome.
In theory you could use it to detect metal or wires in a plaster wall. I've just tried it, and it works quite well. On the other hand, I really don't want to risk electrocution by trusting a telephone to find electrical wires...
My compass is shocking. Actually points closer to South whenever I open Compass or a programme which uses the compass like G-sky. I have to calibrate it every single time.
Thing that annoys me, is if I calibrate, then exit the programme and immediately re-open the programme, it doesn't remember the calibration, it reverts to pointing in a ridiculous direction.
I want to hit it with my fist.
Addtitionally, think it's broken?

Yesterday I found out the same thing... Sometimes I cant even get it working after calibration. I was beginning to think that this happened because I dropped it once pretty hard. What should we do next? Can this be solved by replacement with warranty or something?

Make sure your phone isn't in a case which uses magnets to keep it closed, as they affect the compass. If you're affected, take your phone out of the case and try again. Also, try out in the open, away from structures which may contain a lot of ferrous metal.
In my case the problem is due to powered-on wi-fi module. Turning off wifi, compass works fine. Could Anyone elserepeat my experience?

Just went outside to test it again. And I think I found how to get it working. If i launch the compass application, and try to turn the phone in the flat position (on its back), then the arrow moves in random directions. But if i lift the phone that it is facing straight to my face, and then turn left and right a few times, like a steering wheel, the compass "calibrates" as I can see. And then when I lay it down again flat, it starts to work normally. Can anyone try this, if you understood my instructions?
A more accurate way of calibrating the compass is by rotating the phone twice around each axis, ideally you should do this away from anything metallic or any interfering magnetic fields preferably outside.
Er......
Where is the compass?
I dont seem to have a compass! In my list of apps there just isnt one called compass...
The Analogue Compass app is very buggy for me so I use the Compass app -> http://www.androlib.com/android.application.com-apksoftware-compass-qAC.aspx
When taking readings, I;
Always have to recalibrate on startup as far too many objects cause large interferences within the sensor making it go astray, even the charging cable causes it to go berzerk. The known working routine is to calibrate by fast twisting and turning the phone [I do it after running the built-in figure 8 calibration routine]
Keep it mid-upper body height with no metals nearby (jewellery/belt/metallic objects minimum >5ft away), holding still and level across the x-axis
Point the upper-end of the phone in the direction I want the bearing of (this depends on the type you use though, I use the digital type)
I spin the phone around and then retake 2 more readings for a total of 3 readings - averaging them out for a final mean reading
I only have 2 directions calibrated through professional consultation when this room extension was built a few years back and know the rough directions all sides this property faces, but in particular, I'm 100% sure of the exact degree reading one wall faces. This app using the built-in compass sensor reads that bearing spot on everytime after calibration (fluctuation is 1-2 degree max).
Some friends in a Lithuanian Android forum, suggested to do this, like it is shown in the video. Works perfectly every time. And I thought that something was wrong, because I never had to do anything like this on my G1.

[Q] What's the main reason for you to choose the Sony Smartwatch 3?

In my case,
1. Battery life: I wake up at 6 and go to bed at midnight. The bigger battery, and the transreflective display gives me some peace of mind that I'll not worry that my smartwatch will die when I need it. Also, love the idea of monitoring my sleep and setting an alarm to wake me up at the ideal time (instead of being in the table recharging).
2. Square display: Although round watch faces look classy, I don't like the idea of wasting screen real state for a fancier look.
3. Android Wear: Definitely Google got it right (Unlike Samsung or Apple). A smartwatch complements the smartphone (not replace its features). Simplicity to dismiss discretely notifications, or get directions while using the smartphone for other purpose, or keeping it in your pocket whithout the hassle of picking it up every time I get another notification.
4. Display: As an Ingress player, I'm frequently outside. Sunlight can make most screens difficult to read, or waste too much energy to give maximum luminosity. Transreflective display uses the ambient light, making it perfectly readable at direct sun light and saving energy.
My reason is the mix of fitness watch for running + multimedia (music) without the phone. If that is a BIG YES, all the other features for the rest of the day are welcome but not the main reason to wear it.
For me it would be:
The builtin GPS: ability to hace mapa on the watch even without a phone, or with the phone in a bag or somewhere else with poor reception
Reflective LCD: The benefits of a color screen without the disadvantages of a backlighted one (e.g. no always on, too-bright in the dark, etc.)
microUSB port: no stupid dock that breaks/get lost easily, no proprietary magnetic charging, no fiddling required to get a USB console.

[Review] Elecom Bluetooth Receiver/Amplifier - Bluetooth Streaming on Steroids

This is a quick review of the Elecom LBT-PHP500AV Bluetooth receiver (RF Amplifier, 200mW output). [hands-on pics below in attach and in the box folder]
First of all, wireless streaming is a must for me since I'm using the Sony Xperia Z which has the headphone jack covered with a cap (if the caps become damaged by repeated usage - waterproof phone no more) so I had 3 bluetooth receivers so far, and all of them were a huge dissapointment. I had to use an portable amplifier with the bluetooth receiver which only made things cluttered and complicated, rendering hands-free usage almost impossible.​In my experience with wireless music the top issues are:
Battery limitation (5-6 hours) which isn't enough, not even for half the day;
Low output volume (even if I'm using headphones with high dB sensitivity);
Poor transmission range (which sometimes was a problem eg. gym);
Decent to low sound quality (high quality sound over Bluetooth usually requires spending some serious bucks).
So, after a long search I found, what seems to be the perfect fit between performance and price tag and that is the ELECOM LBT-PHP500AV. I already made a (crappy) review on YouTube and a follow-up, which can be found here https://www.youtube.com/watch?v=S7IaXYDUbOI
The Elecom Bluetooth receiver can be order as stand-alone receiver (about 40$) or with headphones at 50-60$ (which are pretty good - they're about 30$) on eBay(http://www.ebay.com/itm/Elecom-Blue...9&pid=100005&rk=2&rkt=6&sd=261859052253&rt=nc).
Product Specs can be found here: http://www.elecom.co.jp.e.gj.hp.transer.com/news/201404/lbt-par500av/index.html and Headphones specs here: http://www2.elecom.co.jp.e.gj.hp.transer.com/avd/headphone/ehp-c3560/​
When I first saw it, I felt a cosmic attraction not because of how it looks, but because of what it does, which is: almost 4 times the battery life you're getting in a bluetooth headset, high quality audio codecs, transmission range and of course the retro look. Everything seems too good to be true, but now, it became my daily driver and for 50 dollars, it is too good. ​
Without taking this love story any further, I'm going to switch to pros and cons of the elecom bt receiver.
PROS:
Huge battery (they advertise 18 hours of playback) - I've been using it for 3 days without the need to charge it - something that never happened to me. Battery size is 365mAh in contrast to the usual 80-100mAh. This thing lasts more than the phone.
[UPDATE] After using it for 3 days I wanted to fully discharge it... easier said than done - It played for 8 hours continuously on max volume and it didn't even get into low battery mode, and since it was 3am I had to go sleep and just charge it. Long story short, battery should last for about 4 days of everyday usage.
It's fairly loud - I'm no longer using the external amplifier. Cranking the volume on this thing to the max is a bit too loud. Using it with the laptop grants me almost twice the volume i get on my android.
Very nice build, and finishing touches - volume rocker is made of metal which feels really nice. The body is plastic but it feels high quality and resistant to shocks.
Excellent clip functionality - it is plastic but looks and feels pretty solid. The clip has small hooks and on the body side there is rubber that will ensure a firm grip on the fabric (as seen in the video).
Impressive sound quality - no stuttering. Also NFC connect for convenience;
It also works while charging without interruption of any kind while it's plugged or unplugged from power;
Bundle Headphones are pretty pretty good (very unexpected) - Very deep bass with crisp notes ( FQ response of 5Hz - 24 kHz with 99dB sensitivity).
Transmit range - better than my previous receivers it goes 10 extra meters (total of ~20m) before it starts dropping frames.***
CONS:
Headphones wire is way too short.... It doesn't even reach the belt level - this is due to the idea of wearing the receiver around the neck - but it's a bit too big to be clipped near the neck. I guess the cable length won't be an issue (i'm used to really long headphone cables).
No HD-Call support - for me it's not really an issue since i can safely use it as a hands-free (the microphone might pick up too much background noise while in a loud or crowded area).
No battery meter (at least not on android) - which is kinda important - you might not have to charge it 2-3 days but you'll want to know exactly how much battery you have left before leaving the house.
*** The theoretical transmit range of 100m depends on a lot of factors. It does perform better than normal bluetooth headsets but in everyday usage (in enclosed spaces) you probably won't get more than 20 meters of range. Again, it depends on the device you're transmitting from (i use my android phone) and power it reserves for bluetooth operations and the obstructions between transmitter and receiver. It's not really a down point. It's more of a notice.
I've got it from ebay at "trickstar_inc_nippon". I had a great experience with the seller - item was shipped the next day and it got from Japan to Europe in only 3 days. For someone like me who is choosy when it comes to music players, this is a great and powerful headset, on an affordable price. This is an impressive device for it's price and I can safely say it's going to be my daily driver without having to carry the external amplifier or the battery with me.​
I hope the review was helpful (if it was hit Thanks!). Here is a box.com folder with more hands-on pics https://app.box.com/s/oo8ani1ipp97lvnwxr0va17lykx47vre For any questions you can PM me.
Cheers!
@Sebi673 great review on the device. I got one a couple of months ago. Its the same model but did not come with the headphones.
I got this for the battery life.
The big cons for me are
1- I can use my own headphones
2-Battery lasts super super long... I charge it once every couple of weeks.
3- Love the turn off and on button.
The only downsides
- size is little too big than other similar ones.
- Volume control button is little tricky.
How does it last? i read many has problem with dead battery/unit? is it that bad?
Has anyone ever try to replace the battery?

I am still using it daily. And it's over an year old. Battery still holds as it did in the first day. I charge it once every 3-4 days.
Sent from my Xperia X using XDA Labs
Anyone know of good alternatives? I've only been able to find these for ~$120 on ebay and other sites now for the same model. Elecom has some cheaper ones which seem significantly less powered (40 mW vs 200 mw)
Apparently it's on amazon which reflects the price history:

Package content​Doogee X5 along with its accessories comes in a compact box, the design of which is simple, but quite interesting. On the top there is a light-reflecting “X5 Pro” mark, while on the bottom you can see phone’s most important features. On one of the sides of the box, there is a scratch sticker hiding the product authenticity verification code.
Upon opening the box on the side, you can pull out the content of the box – phone, charger, USB cable and short manual. A protective foil is already on the phone, so its new owner doesn’t have to go through the trouble of applying it himself.
The charger is standard, with a generic shape and specifications of 5V 700mA. However, it would surely be better if the manufacturer had provided a charger of at least 1A to shorten the charging period.
The USB cable given with the phone could be used for phone-PC data transfer as well as for charging – it is not limited only to the charging capacity.
The short manual covers the basics of Android OS use, and thus will be useful only to the beginners in the Android world.
The 2400mAh battery is already inside the phone when the buyer gets it, but before he starts using it, he needs to remove the protective foil off of it, as is specified on the box.
The absence of stereo headphones from the package implies that the manufacturer wanted to lower the price as much as possible, which will not bother most of new users, since they will already have headphones of their liking.
Appearance​Doogee X5 Pro has a simple design and the model we received for the purpose of this test is completely black (there is also a black-and-white combination). It is considered to be a phone of average thickness (8.2mm), but you can “feel” it in the hand because of its weight of as much as 130 grams. The battery cover takes most of the phone’s frame, thus in a way protecting it in case of falling on one of its edges.
On the top side of the phone there are connecting ports – a micro USB port (for charging, as well as PC and peripheral devices connection) and a 3.5mm audio connector for headphones.
On the right side there are buttons for sound control and turning the screen on and off. They are very sturdy, well responsive and have a distinguishable click, which makes us think they will endure usage for long period of time.
Microphone and speaker openings are on the bottom side of the phone. As far as sound is concerned, it is very loud and reproduced in satisfactory quality, so the phone can be clearly heard even if it is carried in its own case.
The biggest part of the front side is occupied by a 5.0” display. Even though there was available space for the control buttons to be on the screen itself, the manufacturer decided to place the capacitive buttons (Menu, Home and Back) below the screen. This is a better option for some users, since the entire screen is available at all times, while others will be asking why the buttons aren’t on the screen, since it will additionally make the phone smaller. Unfortunately, capacitive buttons aren’t backlit, which makes them hard to see and use in the dark.
Above the screen you can see the front 2Mpix camera, proximity and light sensors, as well as the speaker opening. In-call sound quality is clear and loud, even in the middle of the sound control bar.
The battery cover is smooth to the touch, but covered in rubber-like plastic in order to prevent slipping and allowing better handling of the phone. Perfectionists will be bothered by the fact that the phone will constantly be covered in finger prints, and so they will have to wipe it with a cloth regularly.
In the upper section of the phone there is a 5Mpix camera, not far from the flash LED. In addition, under that exact spot the Doogee logo is discretely, but clearly visible.
The battery cover is firmly attached to the front of the phone, so we advise careful removal so as not to damage the cover holders, although it is our opinion that they are flexible enough not to break quite so easily.
Upon cover removal you can see the blue 2400mAh battery, above which there are 2 SIM slots (both Micro-SIM sized), as well as the slot for a microSD memory card capacity up to 32GB. In order to access these slots, it is necessary to remove the battery from its setting.
The SIM slots are numbered 1 and 2, but that in no way determines which of the cards will be the primary one, since the user himself can choose which card to use for calling, messaging, surfing the mobile Internet (4G!), etc.
The phone’s surface looks impressive even though this is a budget phone. Yes, there are small traces of plastic injection near microUSB port opening and 3.5mm audio port, but it is barely noticeable and in no way diminishes the beauty of the phone. It is a pity that X5 Pro is missing the notification LED, since it would eliminate the need to turn the screen on in order to check for any missing calls or text messages.
Display​Doogee X5 Pro comes with IPS 5.0” display with 720p resolution (1280x720 pixels). This makes it a very good choice for a screen of this diagonal, because the pixel density is high enough so that the image is as clear as it can be expected although there are phones with much higher resolution on today’s market. We have secretly feared that colors would seem washed out while the visibility angles would be narrow, but that is not the case at all in X5 Pro. Color intensity is fairly good, whilst image rendition stays the same until viewing in extremely sharp angles. The manufacturer states that the phone comes with Gorilla Glass display protection, but it remains untested in that aspect.
Screen reacts to the touch very well and it’s responsive in 2 points at the same time, that’s enough for most uses, including playing games. The only problem we noticed it’s that it reacts a bit unprecise when fingers are too close to each other, that makes a pinch-to-zoom gesture a bit difficult.
Back lighting can be very intense, which makes the displayed content visible even in direct sun.
Software​What is interesting is that Doogee X5 Pro comes with Android 5.1 (Lollipop) OS, which means the phone is adorned with both good hardware and optimized software. Software appearance and its functions do not differ excessively from Google source code, although there are certain additional phone setting functions offering further possibilities.
Android 5.1 has finally brought dual SIM native support, so manufacturers have no need to create their own solution to the “problem” of selecting SIM cards in lie with each situation. When a SIM-using app is run (Dialer, Messaging, Hangouts, etc.), notification menu displays the possibility to choose which SIM card will be used at that point. It is also possible to predetermine the use for each card, further simplifying the entire process.
It is possible to turn on certain gestures to facilitate phone use, such as flipping the phone onto the screen in order to silence ringing, answering a call by lifting the phone a bit more quickly, or simply switching to speakerphone and back by bringing the phone closer to the ear.
What is more, the phone has the option of turning on with a double display touch (Double-tap to Wake), sliding down on the screen while turned off in order to quickly run the camera, or writing on the screen to run apps like dialer, Internet browser, Play store, messenger, etc.
The “Visitor mode” solves the problem many have been dealing with since the appearance of mobile phones – denying access to certain parts of the phone. By activating this particular mode, you can hide call lists, SMS messages, pictures and disable modification of main screens on the phone. This is an excellent option to activate before lending your phone to a friend. However, in order to turn this option on and off, you need to enter your PIN.
Similar effect can be achieved by means of “AppLock” app, which does exactly what its name indicates – locks apps, and provides access upon entering the PIN.
Moreover, the proximity sensor also has certain phone management functions. By waving your hand above the sensor, you can scroll pictures, shuffle songs, take photos, change pages in launcher, unlock the phone and answer a call. As to how smart of an idea this is, we will let you decide.
More advanced users will like the built-in option of controlling app permissions (Permission Manager), which means that any app can be simply revoked the permission to dial, send messages, read location, access contacts, use camera, etc.
All in all, Doogee X5 Pro has left a favorable impression as far as OS and additional apps are concerned. Thanks to Android 5.1 OS, animations are beautiful and fluid, transition between apps is fast (for which large RAM memory can be credited, 2GB) and there wasn’t even an instance of unexplainable lag. With basic preinstalled apps installed, only 500MB RAM is occupied, thus leaving a lot of space for installing and multitasking between large numbers of apps.
Camera​As previously stated, Doogee X5 Pro on its back has a 5Mpix camera (interpolated to 8Mpix) with very limited possibilities, while on the front it carries a 2.0Mpix camera for video chats.
The 5Mpix camera has autofocus, LED flash and makes 2560x1920 pixel pictures without interpolation.
Camera sensor possibilities are quite poor. While colors are good in the daylight, it lacks detail even while taking photos with a steady hand. Photos seem good on the screen, but when zoomed to their original size, there is a visible lack of sharpness and “oil-on-canvass” effect. Photos of closer objects are satisfactory in sharpness, but most landscapes make you want to give up the sport. This is quite a shame, since the camera software has interesting options such as automatic photographing by lifting 2 fingers in the shot, automatized following of an object and taking its picture, recording “live” (making a 5-second long video with a photographing effect) and the Face beauty mode, which removes skin imperfections and makes you more pretty (the fare sex loves this option in Samsung phones).
Photo samples:
Battery Life​Doogee X5 Pro comes with a 2400mAh battery, which is enough capacity to allow the phone one-day autonomy with more intensive use. Seeing how the processor is economical and works on lower frequency, battery consumption is moderate. We have measured its autonomy by inserting 2 SIM cards into the phone (one in the 3G/4G mode and the other in the 2G mode) and running synthetic tests, making a few shorter phone calls (about 20 minutes in total), taking pictures outside for about an hour and a half (during which time mobile Internet was active), testing its speed of access to the 4G network, and then surfing the Internet using WiFi connection.
During all that, the screen was on for 4 hours and 30 minutes, while the phone was off the charger for 30 hours! We believe this to be an excellent score considering all this phone’s features.
Performance​Doogee X5 Pro is based on MediaTek MT6735 64-bit chipset which is increasingly present in lower-middle class models. MT6735 has a Quad-Core processor at 1GHz (988MHz, to be more precise), Mali-T720 graphic chip and 2GB of built-in RAM memory.
The processor is probably intentionally limited to lower frequency instead its maximum (1.3GHz) in order to provide a better battery autonomy, since it has proven to be quite economical and still powerful enough for most users’ needs. Judging by synthetic tests, MT6735 chipset at 1GHz frequency performs in the rank of Snapdragon 400 chipset and its Quad-Core processor, which is an excellent trait considering the price of X5 Pro phone.
It also has built-in USB OTG option, so it is possible to connect USB flash drive or USB mouse or keyboard directly to the phone using USB OTG adapter.
Obtaining GPS location on this phone is quick and precise, since it easily finds a large number of satellites and connects to most of them in 30 seconds. Therefore, it can definitely be used as GPS navigation with matching navigation software.
Benchmark tests results:
Conclusion​Doogee X5 Pro is a smart phone which has suddenly appeared on the market and attracted a lot of attention with its surreal hardware for a good price. Its IPS display with wide visibility angles and quality rendition will allow undisturbed use in all conditions, while its work speed will satisfy all less and moderately demanding users. If you want an affordable smartphone and you can look past a few smaller cons, there is no reason to be apprehensive – you should definitely take the X5 Pro model into consideration as best buy in the lower price range!
Pros:
Good quality display
Fast response
4G LTE support
Powerful speaker
Cons:
No notification LED
Capacitive buttons unlit
No gyroscope and g-sensor
Once more, big thanks to Pandawill for providing a sample device for testing.

Great review, thanks.
Could it be possible to overclock the CPU to 1.3 GHz when the device is rooted?
I saw one review (here) that had an Antutu benchmark of around 30000. It is an early review (August 30th), so perhaps it was an early demo phone that was clocked higher?
You're welcome.
I think it can't be overclocked. Not with the stock kernel, anyway. To phone runs cool, even with the maximum CPU load (about 30C), so I do think the CPU has potential to withstand OC to ~1.2GHz, but there isn't a way at the moment.
As I detailed in this now closed thread, I am unable to get this phone to operate at anything faster than 2G network speeds. The specs of this phone would appear to keep it out of the 4G (or even 3G) range for AT&T in the USA, and indeed, most every other USA carrier I'm aware of. Such a sadness because this is really a nice phone at such a good price.
Excellent phone
Ive had this phone for about 3 weeks now.
Its an awesome phone for the money.
Im not a fan of how branded companies charge huge profit margins like HTC and samsung.
This phone has all I need.
It has 3G and 4G LTE which work great in my country (New Zealand).
In fact the antenna is very strong compared to my old samsung.
The camera is fine for me at 5MP, the autofocus works well and ive been able to take some really nice pics, better than the ones in the review above. Closeups are excellent. If you hold down the shutter button you get something like 6 to 7 shots per second which are then saved as a progression of pics that are then viewable in gallery as a kind of gif animation with each frame been able to be used as a photo. Theres tons of features built in. I really like that no tweaking is needed out of the box.
I installed Hola launcher as I just like its style, its faster than stock launcher and organizes apps into easy folders and it has built in weather and intuitive interface that works really well with this phone.
Ive always bought phones with hardware buttons. I cant stand phones with on screen buttons. It just takes away from everything.
So much nicer having real buttons.
Im happy there is no notification LED. This used to annoy me on my samsung and my smart 4 especially at night time I dont like any flashing LEDS in my room when im sleeping.
Double tap to wake up is nice and also useful when i have it on my car bracket.
Only cons so far are that OTG doesnt seem to work currently. Im guessing the phone needs to be rooted to use that feature and as others have noted there doesnt appear to be an easy root method as yet.
its a shame it doesnt have gyro because my google cardboard isnt much use, but i guess i can still watch 3d movies with it.
Hey.. good news.. looks like KIngroot have updated their app because I just opened kingroot and it says 92 requests received and a strategy is been worked out, which is better than last week. I will try to root manually anyway today. Id really like OTG access.

OTG works fine for me. I'm just using a bog-standard OTG adapter and a FAT32-formatted USB thumbdrive.
I'm still looking forward to a working root though.

Ok maybe my home made OTG cable is the problem.. i just used my data cable with a female to female adaptor on the end.. mayb e that doesnt actually work?
[FIXED] used a correct OTG cable and its all working great! no need to root this phone for any reason now!
I don't know why the rooting thread has been locked, but rooting and installing TWRP is really easy:

I used Rashr to flash TWRP recovery.
Woof
Doesn't work if you have already updated via wireless update.
Phone won't accept the update.zip I you've updated already.
Only via factory reset first. That's our problem.
I stick with a R5 because of rooting problems above that Version.
Ok
OK good to know.. Don't need root at this stage as otg is working now.. Phones still fast so no major advnatge to root for me at present..

Really?
I'm on DOOGEE-X5pro-Android5.1-R08-2015.10.26 and root worked fine.
I had two updates applied from when I received my phone.
Good news, did you had to root again after update?
I rooted for the first time after applying all the updates. Only recently made sense of the rooting thread! Don't know if it'll create problems if there's another update, but I'll cross that bridge when I come to it.

ok thanks maybe i will try again...

How did you do to root?
I have R08-2015.10.26 but I am unable to root (install supersu)
I followed the procedure of wireless update → select update.zip and click ok. When the phone reboot, it start the install but stops and show "error".

See the method in a previous post in this thread. I don't know why you get an error. Did you follow the method to the letter and use the SuperSU from the Mega link?

yep
yepn same problem for me.. used mega link file and it just says error a third of the way through.. seems a common problem for some users...

Problems with Gamepad Moto Mod. Calibration?

Has anyone tinkered with the guts of the moto mod gamepad? I'm having an odd issue with the analog sticks. In apps with high sensitivity to stick position, I don't get the full range of motion in certain directions. This is almost certainly a factory calibration problem... on a PC I could just calibrate the device directly or find a workaround, but I don't know enough about android accessories/devices. Short of ripping it open and futzing with what I assume are hall sensors, is there a way to initiate some sort of device re-calibration, or change the values for 0 to max in Android?
I've sent a similar question to Lenovomoto, but I'm not hopeful.
Edit: I'm too green to upload images here, but gamepad tester output shows a 'flat tire' response from 11-oclock to 1 oclock.
I rock the stratus steelseries XL for Android gaming. It has never let me down....and paired with the projector mod is an epic combo... I would just return it get the controller and hold out for your promo..unless you already have it..then ur set...

It sounds like a DOA gamepad. Out of the box mine hasn't had to be calibrated and has a natural controller feel. The only thing I notices is the D-Pad required firm pressure at times.
my gamepad doesn't seem to have any of those type issues:
https://youtu.be/8zndTsQgKf0
have you checked for a software update?
No updates yet, though I do suspect it could be corrected in software, so here's hoping. In the meantime, it looks like in-game sensitivity adjustments provide a suitable workaround for most games and emulators. (just boost the sensitivity to the point where all directions register) I'll just have to wait patiently - despite providing raw output data, Moto customer service doesn't regard this as a defect.
I have had the same issue with my original gamepad mod and the replacement. I've deducted mine to trigger slop. No teardowns I've found yet. And I called Lenovo about it and they said no calibration tools available. Make sure your forward directions are not sloppy. On both analogs I get .8 travel out of 1 in all forward directions on both sticks. Trying to figure out how to fix lenovos poor design and crappy plastic parts myself. Glhf.
I Solved this problem on my gamepad
My way is a bit tryhard, but... I found this teardown from a guy who was replacing the membrane from the D-Pad, I can't post links cause I'm a new user, but if you search for "moto gamepad disassembly" in google, click the third link that says "Moto GamePad Mod - better buttons! : Moto_Z - Reddit" and then go to the link at the bottom of the thread (thanks very much to that hero).
So... following those steps I removed the stick and used sandpaper to expand the radius of the circle that limits the movement of the stick. When you are getting close to the grey ring, you are done. At that point the stick can reach from -1 to 1 values on every direction you point it.
If you want to do it, I have a couple of tips... In the second step of the teardown you have to use a bit of strength to separate the shell on the top and bottom corners that point to the center of the gamepad. And I recommend to use a hard sandpaper at the start and when you are close to the grey ring use a soft one.
Sorry if I don't write very well, I don't speak much english.
