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?

Yes I know that. Tried out doors, and wheres no metal... When I had the G1, the compass worked normally.

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.

Looking in location settings and there are three options. Use wireless network, use gps, and use sensors. Ive never seen the "use sensors" option before? Im assuming for best gps performance is to have all three checked?
I'm interested to know this as well...

Well the description that pops up when you check it elaborates pretty well. From what I gathered, it's mainly meant to be used as a battery saver when you're using the GPS walking around, especially indoors. What I think it's doing is using things such as the accelerometer and compass to aid the GPS in determining the direction and speed that you're moving in, thus meaning the GPS doesn't need to actively search for your signal as hard, which would drain your battery when that signal is weak (I.e, indoors).
What really excites me about this feature is not the battery savings,but the potential that the gps might now finally be able to keep a lock in an urban downtown. I live in , so the mountains combined with the buildings means that once I set foot downtown my gps is next to useless. This new feature seems to have the capability to eliminate that.
Plus, it might result in overall accuracy improvement in any generic gps scenario.

Im sure sensors mean accelerometer/gyroscope for navigation while driving? Like when you hit the brakes, accelerate, turn, etc. seems cool
Edit: and what squshy said lol
Coming from an Evo 4G and only used Google Navigation once in my car so far. I enabled the sensors for GPS when it prompted, and I noticed the tracking was off when the car was stopped, mainly at an intersection.
It showed me moving back and forth on the road, enough that it showed crossing the intersection, and twice it showed me turning. Again this was all while still but I was holding the phone when looking.
So maybe by sensor they mean the motion sensors and the slight movements were putting it off? I'll be using it again today and I'll try with the sensors for GPS disabled.
And just to add, overall the GPS still worked in terms of getting me where I needed to go, just haven't seen that kind of tracking jitter from the Evo.

I get the description but im curious if this is a setting we should leave on all the time or if it is better used for specific uses.
Haven't driven yet but did bit of Googling. I'm conditioning the battery, bored waiting for it to charge fully, lol.
squshy 7 has it in that it's the gyro motion sensors. A few other Samsung phones with the feature say that's it's meant for pedestrian navigation and urban areas where it's having a trouble tracking enough satellites.
Samsung's docs didn't say anything about disabling it outside those scenarios, but there are some forum posts regarding GPS stability issues and people seemed to have better results when they disabled sensor aiding for driving.
Some users mentioned that calibrating the gyro motion sensors and the compass helped. One Samsung user guide said to keep the phone flat and pointing in the direction you're moving and to avoid any magnetic fields.
So still testing it later while driving, also going to try both on and off while doing walking navigation. I'm in downtown LA so I'll be able to test the urban effect.
There's a good sized thread on the Galaxy S II forums about gps issues. Skimming around it looks like it's split between people saying GPS is fine and otherwise.

Good info. Since i live in a rural area i may just disable it for now.
Hi there Everyone!
This is my Yureka Review, I got this Phone on 24th, Without Wasting Time...
Let's hit it
Please Correct me If I'm Wrong
1. Camera- So, This Phone's got A 13 MP back camera and 5MP front Camera...
The 13MP camera is great for Low Light Photos and Daylight pics are Awesome...
The CM camera App makes photos even Good...
The Back Camera shoots great Photos and Focus Makes it More Good...
The Front Cam is Awesome for taking Selfies with Camera Angle 88°... Really Great... I tell You!
2. Talking about the OS, It's got Cyanogen OS 11... Those who've used CyanogenMod may find it less customizable but those who haven't, Surely You'll love to Modify it...
3.Hardware
It's hardware is pretty good in ₹9K, I was getting the AnTuTu Benchmark Score 31291
I tell you, It's Really Great!!
4. Build Quality- The Phone is Nicely Made, With an LED Notifier at Top...
Volume Buttons on Left and Power Button at nearly Mid-Right
Jack at Top and Power at Bottom
If you get to Hold it, You'll Say- Man! It's so Light!
Yes!The first time I took it up, I thought the battery was not there put up inside but I was wrong, Even though the battery was there, It was light as air...
Well, Not actually...
It's Slim As Well, Quite Slim
I'm sure he was on workout and Dieting...
The back feels like some Carpet is put up... So comfortable and Strong Grip...
5. Bugs-
Now the Cons.
1. Phone gets heated up quick even if you're Running Facebook... But What I mean with Heating is, it gets lil warm at the top back... Nothing Much...
2. MY QUIZ UP RESTARTS OFTEN WHILE PLAYING...
3.As reported by our Forum Member Ajith, the charging get stuck at 99% and some Frames get missed even on Temple Run
But these Bugs are mostly, All most, Software bugs; Which Cyanogen has Promised to Kick 'em Over in Software Updates Coming in Feb...
So if you're looking to buy a phone Under ₹15000 for Now,
Surely, No doubt, Go for Yu Yureka...
But It's not that easy To get it...
Thanks For reading...

hi are you facing any of this problems i heard in the form that many are facing this kind of problem. kindly provide your review as i am thinking of buying this mobile
Wifi issue and random reboot issue
Battery drain (as expected) issue
camera issue (Some facing)
WIFI SUCKING battery
HEATING ISSUE (WATER HEATER)
Proximity issue While making calls
rear camera issue
Nope, Not any, I don't know why are they getting Reboot Bugs? Surely Go for it... Even if there's any problem, They'll fix it!

There is an issue with the proximity sensor, its not working some times.
Heating issue is present but it depends up on the apps. playing games like NFS is causing more heat than any normal games.
Rear cam is damn good no issues about that. never faced WIFI and random reboot issues
Yes, You might be having them but you see, They are only Software Bugs... Don't worry Man! We have software Updates Support...
There are many software bugs.
I think Cyanogen will fix all the bugs in future updates. No software is perfect out of the box! Let's see how cyanogen deals with the promises along with YU.
Reboot issue
I own Yureka & my phone restarted once or twice when I play game, especially Clash of Clans.
I guess this is the CPU heat issue, still checking. I have underclocked CPU to check if phone reboots randomly or not.
Will post results. Meanwhile if anyone have solution, I would be happy.
GK.

Hi,
So with these kind of issues like heating/reboot, etc.... you mean to say that we have some kind of solutions, and not to bother though every phone faces the same issues, if am i correct.
And, we can go and grab this phone though we get it below 10k which has good features where we dont sunch phone.
I'm impressed with 2GB-RAM mostly.

Hi. Thank you for reply.
Finally I have found solution.
I underclocked CPU to min 400 max 800 MHZ and set IO scheduler to noop (that is FIFO with very less CPU cycles)
I have found considerable less heat issue now without any lagging with COC. Also now battery lasts much longer than earlier. I am very happy. Cheers !
You could use this as a reference
Hey! For those wondering how the camera on the Yureka really is, here's a screencast of the same so that you get a feel of what it really is! youtu.be/oSkgd8jwCKs

Else search for screen cast recordings on youtube of each phone. You'll get a feel of how the camera really is
Hello I would like to share something I found out about the fingerprint scanner, that worked for me and hopefully for you as well.
When I received my Elephone P8000 I was disappointed that the fingerprint scanner didn't work as well as I hoped (about 50% success rate).
First I thought it was the Phone, but actually it was my own fault. and now it works 99% of the time
The wrong way: when adding a new fingerprint, I placed my finger at the exact same spot every time while configuring.
The good way: hold the phone like you normally would when unlocking the phone, and place your finger at slightly different places on the scanner when configuring (do not center your finger at the exact same spot).
I hope this helps.
That's the way I've done it since I bought the phone and my success rate when using the fingerprint scanner must be around 90% (no kidding).

Same here. Actually, I think my success rate on the fingerprint scanner is higher than 90%.
I'm getting good results from this
Depends on fingers skin too. Scanner dosn't recognise fingers a lot when having dry skin(washed hands a lot in a day) and had normal skin when entering prints.
Thanks for sharing, i getting 90% success rate with this method.

Auto brightness never worked well on any of my Samsung's, uses excessive battery pi$$es off my retinas, so i always use manual control. It's not just a Pixel thing
Personally I rather see a review where the reviewer finds flaws and pick away at them; it shows candor. The endless mainstream reviews of Samsung flagship duds that give them glowing reviews to boost sales are so old and predictable. Reddit gives better reviews
Updates break things. Upgrades destroy worlds.
Leave it be unless you see them working miracles for other users after a couple months. Trust more what individual users and small fry reviewers say than CNET, Tom's Guide, Phonearena, etc.
Take what you got, optimize it, and find work arounds rather than constantly updating and upgrading it. Every time you update and especially upgrades you change the playing field and you can end up starting the optimization/work around process all over again. Like a reoccurring nightmare. Who wants a phone with an identity crisis that's constantly morphing into variants you have no control over?
I want a fast, stable, reliable platform that fulfills its mission. I have no desire to be an unpaid perpetual bataware tester for something I paid big bucks for!
You may not agree with what I just stated. I don't respond to sales/scare hype. I want to see rubber biting into the bloody asphalt not just a cloud of smoke and noise.
Case in point is this N10+ in my hand still running extremely well on Pie. Current load will be 2 yo this June. It's fast, stable with minimal maintenance and bug free. I spend very little time troubleshooting it now. Security is not an issue.
It does exactly what it should be doing, working.
I'm currently looking for another phone as the signal is so poor on this chipset and Google has locked it down so I can't get 5G or Volte even though my network is supported they won't unlock it
I think he needs to RMA his phone, because I did that as well. Amazing experience after it!!
Interesting, i have a Pixel 6 Pro, my wife has a Pixel 6 and my best mate has a Pixel 6 Pro and apart from the fingerprint sensor being a bit off to start with i cant say we have had any problems since the phone came out.
I've never known adaptive brightness work particulaly well on any phone i have owned to be honest so thats just the norm for me.
I agree with his take.
Auto-brightness has been abysmal on this phone since the beginning. It really shouldn't be, not when they're employing two ambient light sensors. It's especially painful because I use the device in dark environments very often (have a baby, use it to play sleeps sounds to him while he falls asleep) and it never assesses the brightness correctly. The torch thing is also a massive irritation, since it ramps the display brightness up to max in a pitch dark setting, then takes an age to eventually move down to a more acceptable brightness, but not without blinding you first.
I've never had this problem with any Samsung device employing dual ambient brightness sensors; on the contrary, I've always found the brightness settings to be close to perfect on these devices, even the ones where the front sensor shifted under the screen.
Signal is a significant weakness on this phone as well. Whenever I pop to the stores, I regularly find myself without signal when inside the store. I have to literally walk out and walk back in to restore some signal in case I need to call my wife or message her. I can honestly say that weak signal is not the biggest issue to me, it's that is just about disappears in places I have had no issue with other devices. And it's also something that seems to be a problem for me with Pixels, at least on my carrier. This is just the worst I've experienced by a long shot and has me pausing for safety reasons.
The fingerprint reader is not great, but it's much less terrible than it was at the beginning. I've not been as impressed with the cameras as I thought I would
There are still weird bugs (Google Assistant randomly pops up from time to time; changing wallpapers causes the quick settings toggles to disappear until you fully open the notification panel; the April update randomly reset all my custom notification tones; app search sporadically stops working; lift to wake and tap to wake still way too sensitive) and Google has actually regressed in some UX aspects (removing the vibrate icon from the main status bar; the internet tile; the choice of UX around the always on display; etc) compared to even Android 11.
Overall, this is still a great device, and fluidity of the experience is second to none. Too bad about the almost unbearable signal and effectively non-functional auto-brightness.

thats why i said on any phone i have owned.
The voice to text is strangely broken on this phone. I see many people complain about it specifically on the 6, whereas all previous pixels had excellent voice text accuracy. I still use it primarily for messaging and just accept that people think I'm illiterate.
I'd agreed with the hardware issues. The antenna isn't as good as any of Qualcomm's recent stuff in signal and battery, and the fingerprint reader (which I'd probably rate as "fine" at this point) is still a notable dropoff from the one on the back of the phone.
But there's other complaints from that video that have never been a problem here. Wi-Fi Calling is the one that sticks out that's been great on my device.
