Develop Bugs

New to the android SDK

hello XDA world! i had a couple of questions i was hoping someone may help me with
running on MBP with 10.6.5, installed "Eclipse IDE for Java Developers
Version: Helios Service Release 1
Build id: 20100917-0705
clicked on the android.apk under tools and updated all. then went to eclipse and help-install new software.
am i ready? somewhere a read something about updating your path with .bash_profile? that part makes absolutely no sense to me at all. i know only a little terminal from ubuntu, may have figured it out just now, i went to eclipse preferences and added the path from the downloads folder.
ok so now am i ready?
cant anyone provide me with links to how to use this to make my own roms. or any good getting started links? id really appreciate it.
p.s. can someone explain framework to me, i want to know why ASOP roms cant have 4g or HDMI, or if its possible to make a hybrid rom like frost with all the sense removed while staying on the sense framework and not breaking it?
lastly, can i get my phone replaced because of false advertisement or limitations of hardware? i mean i have been wiping and flashing different roms testing them and no-matter what rom or setup i have i still get jitters and all around crappy GUI. next to my friends galaxy S my phone just seems defective and choppy, granted with the newer roms and fps unlocked, its still not close to as smooth as the galaxy S in terms of usability, is the hummingbird that much better or is it poorly written drivers for the snapdragon that makes it inferior?
if i took my phone up to best buy and had them look at it next to a galaxy s model what chances are there that i could replace it because of the overall inferior android experience? when i opened up pocked legends at the same time on both phones i was blown away that the galaxy s was indeed smooth while on my evo the gameplay was choppy like the game was not getting enough
FPS. although fps2d says it gets around 54, i have HDW 0003. any additional info would be helpful sorry that im so inquisitive today i just decided i wanted to know if my phone was the right choice for me.

Doogee x30 (32-bit) :: An Un-Boxing and Review

Introductions ::
Hello there, and welcome to my review of the DOOGEE x30 (32-bit – not L) smartphone! As a casual technology enthusiast, this sort of product truly fuels my interest in the mobile device industry. Manufacturers, like DOOGEE, constantly raise the bar of expectancy-vs-price, by either introducing highly sought-after features to cheaper devices or creating entirely new features that are then introduced through the budget market first. This practice of constantly improving the developing the low-end market makes for an interesting show when one goes to observe the ripples that this creates in the mobile device market as a while. These manufacturers, when they get the formula just right, create devices that can competently perform at a low price point, while displaying very little compromise in overall design, features, and quality. As such, I find the budget market to be an important part of the general mobile device market(place).
Now, for a bit of personal background. This is my third smartphone from DOOGEE, which means that I have a slight, inherent bias. However, I will do my best to curb such, for the sake of an honest and fair assessment of the device in question. I will start with the un-boxing experience, and move forward from there in a semi-natural progression, if you will. The included clips will (unfortunately) be presented in 720p30fps - not true HD. But, it should get the un-boxing experience across in a satisfactory manner - I hope.
Specs ::
Can be found here.
Un-Boxing ::
approx. 15 minutes long
https://www.youtube.com/watch?v=VI_cLORLc24
* Please note that the first part (the un-boxing) is still being processed, and the second part (the actual review) will be uploaded later this week (and hopefully, in a higher resolution). I hope you all are enjoying your winter holiday this year
Review ::
There is none - it's ded
Pros ::
The CPU is an MTK 6580, which is clocked at 1.3GHz - a decent CPU for this SoC, although 32-bit.*
This phone comes with 2GB of LPDDR3 RAM, which is better than what many other budget smartphones come with (less than 1GB in many cases). In fact, this SoC could be packed with up to 4GB of RAM if they wanted…
The 4-sensor Camera system truly sets this device apart from the competition in terms of photographic capabilities at this price-point (60-100 USD). They record at 5mp and 8mp respectively, meaning that the maximum resolution you can get for an image (from the rear cameras) is 3264 x 2448. Pretty nice for a sub-100 USD smartphone...
The metal frame also helps in terms of durability, and even adds to the overall visual appeal of the phone’s design.
The curved body makes it easy to hold, and ergonomically pleasing to the average user. No pain in the palms to speak of
The phone comes with Android 7, which is a great move - Android 8 is here, and DOOGEE can push an update whenever they’re ready. In addition to that (assuming that DOOGEE does update this phone), it gives users the option to decide on whether or not to move on to 8 - software options. But, while you’re waiting, you can play around with Quick Settings Customization - which is another plus.
This phone comes with 16GB of internal storage as an entry model, in opposed to 8GB (as seen in past models like the x5 and x6). This move is definitely one in the right direction…
The software that comes installed on this device initially appears quite close to stock (Google Apps and all - beyond AOSP) Android, which is great for those of you who want more control over the experience, or a simpler experience when using Android. It’s pretty difficult to spot most of the differences and deviations...
Cons ::
This model’s CPU is 32-bit, which limits the RAM and apps that can be used on this device. As such, it won’t be able to use any software that requires a 64-bit* architecture or more than 4GB of RAM. Remember the x5 Pro and x6 Pro models?
The RAM speed on this device is only 533MHz, which leaves it feeling like low-price DDR2/LPDDR2 (at around 500-600MHz), in opposed to the LPDDR3 it’s actually packing, which (in theory) can reach speeds of around 800MHz.
The Mali GPU included on this SoC is only 2 cores*, which is a bit underwhelming for obvious reasons. A higher clock speed could have helped this a bit.
It comes with some unnecessary apps, which can’t be completely removed without rooting. This needlessly reduces the amount of free storage space on the device. What’s up with the cat hanging from the top of the screen?! The approach used on the x5 and x6 Pro models should be used on this device instead.
It’s theme, while small in terms of performance impact, is an unnecessary and non-innovative deviation from a simpler Google/AOSP UI experience. Once again, the approach used on the x5 and x6 Pro models should be used on this device instead.
The screen, while being HD-Ready, is of the 720p/1080i variety - not the Full HD (1080p) that many have come to expect from their smartphones nowadays. But, this isn’t too much to bare.
The camera(s) only record at 5mp and 8mp respectively, meaning that the maximum resolution you can ever get for an image (from the rear cameras) is 3264 x 2448. While still images are quite nice, video recordings are locked in at 30fps, and may actually be at a lower resolution still.
This device can only receive so much expansion via the SD card slot - 32GB to be exact.
The SoC on this model doesn’t offer 4G(LTE)* capabilities, Bluetooth 5, NFC, or Wireless Charging.
It’s USB 2.0, instead of 3.0. An upgrade to 3.0 would have been nice...
Not so sure about how honest DOOGEE is about the camera.
Some apps I would remove (if I could) include:
Torch*
Themes **
System Manager**
File Manager**
DOOGEE ?
Chrome *g
* Integrate this feature into the Quick Settings - no need for another app
** Can be handled better with 3rd party apps
*g Have better counterparts that are developed by Google, and should be decided on by the user
? What does this app do?! I don’t remember it being around on the older models...
Conclusion ::
Overall, I think that this device is quite nicely-made for this price (60-70 USD), but could be improved upon a bit. While being a worthy successor to the single-digit x-models, I also think that there should be a higher-end model available, for those of us who are willing to pay to have many of these issues alleviated (around say, 100 USD - like last time). In addition to this, from having had the x5 Pro and x6 Pro models, I can’t help but feel just a bit let down this time around. Yet, there isn’t an x30 Pro. Perhaps the x30L* would answer the call? Although, I haven’t been able to find the darned thing, for sale, anywhere!
Overall Rating: 7.0/10
Bottom Line;
Good show, DOOGEE. You do have some places where you can improve. But, I can’t wait to see what you come up with next...

I actually purchased this phone for the mother-in-law. It literally just arrived today. Off the top, it's a very nice phone, especially for the sub-$70 I paid for it. I'm going to be working with this in-depth over the next few days in order to customize it (and see what tricks I can find). I'll report back when I'm done.
UPDATE: Just got this TWRP'd and rooted. Now I can see what this thing can do. :good:

Here we go!...

Good to hear! I enjoy reviews of these smaller brands. Not everyone can afford a Note 8 cash-out.
I got a few more technical notes. Apologies if I ramble a bit, but I wanted to get this listed so that I don't forget. (Please let me know if you want me to post my root method as I don't want to hijack your thread. I didn't see any other threads pertinent to this phone posted yet.) These notes have to do with modding the phone and how it behaved for me afterwards.
As mentioned earlier, I rooted this phone after playing with the stock version a bit. A note about rooting - there are several posts online that mention rooting via SP Flash Tool. I never got this to work for me. Instead, using ADB and the TWRP version for this phone did the job (there is a trick in doing so as the install wasn't quite so straightforward). Once TWRP was installed, flashing SuperSU went as usual. Root Checker confirmed that root did take.
Custom recovery was possible because Doogee X30's flavor of Nougat 7.0 (which btw this phone has one of the few maker-created launchers that I pretty much like) contains a switch in Settings that allows you to make the bootloader unlockable. A quick run through ADB to actually do the unlocking worked perfectly. However, I now have a "Status Orange" message upon boot-up that claims the phone is now unsafe due to the bootloader unlock. But this doesn't seem to adversely impact operation (at least nothing obvious has presented itself) - very similar to the message I got when I did the same thing to the Galaxy Note 4.
I was able to use Kernel Auditor to do thinks like speed up the CPU and enable init.d (one of the requirements to get Viper4Android to work). CPU tweaks substantially enhanced this phone's performance.
Once rooted, customization became relatively easy. I targeted my usual apps to enhance the phone. SELinux Switcher, Adaway, BusyBox, Kernel Auditor (to tweak CPU performance and enable init.d), and Viper4Android (the package that includes Sony + Dolby Atmos). Rooted apps are all performing as expected.
The factory launcher is surprisingly lite and simple, and I did enjoy it. I would have kept it for the MIL, but I didn't see any obvious way to change the icon set so I went with Evie Launcher (if you see a way, though, please let me know). So far, Evie is working quite nicely.
Wifi speeds are pretty good for a phone in this class; I have no complaints. For cell data, based on the radios supported, this phone can only work at 3G/HSPA+ as there is no LTE radio. However I'll better be able to speak on that once I put in her SIM card and really give this a twirl on AT&T towers.
With the right modifications, I'd say this phone performs similar to those with a much higher pay point. Of course it's nothing near flagship level. However, for the amount of RAM and on-board storage, SD card support, headphone jack and REMOVABLE battery - I'd say this phone is a pretty sweet deal especially for people who just cannot or do not want to spend $$$ for a bunch of features they don't need. Plus if you break this sucker, you're not gonna cry over it. Just save up a few In-and-Out combos in a piggy bank and you can buy another one.
Oh yeah - one final note. Regarding cases, unless you want to pay Amazon's ridiculously jacked-up prices, it's best to order one through eBay from overseas. I got the pleather wallet model and it looks pretty decent. Just saw there is now a genuine full-leather one also on eBay.
---------- Post added at 05:25 PM ---------- Previous post was at 05:19 PM ----------
Oh darn it! I just saw that you wanted to remove some system apps. Once rooted, there are apps in Playstore that should let you do just that.
In fact, thanks for that list. I'll check these out and see which ones I can dump. Is Themes tied to the launcher? If so, I may not touch it to avoid problems later. Speaking of Theme - that effing hanging cat can be turned off in the stock launcher settings. There is actually a switch for it. Sooooo annoying!
And your rating is very close to what others are giving (low to mid 7s), so it looks like your instincts are quite on the money.

Just added the first video. Once again, I'm kinda wishing that my dedicated camera was still operational (Nikon COOLPIX), but it stopped working a few months back. I had no option but the Nexus 7 camera (again). I've been using it as my camera for most of my videos where it isn't screen cap.

care to expand on TWRP rooting?!
(there is a trick in doing so as the install wasn't quite so straightforward)

For those wondering how to root this phone, its actually pretty simple. THIS WILL ERASE EVERYTHING.
Assuming you know some basic adb commands..
You wanna start off with making sure your bootloader is unlocked, which can be done fairly easily with ADB tools.
Don't be alarmed when your phone resets a couple times, its erasing data and reformating.
Once your bootloader is unlocked and your phone restarts, remember to reenable USB debugging. and then go to fastboot mode again to flash our recovery.
(I used the recovery link listed in the SUflash method that comes up when googling 'x30 doogee root')
Once our recovery is installed, we'll wanna put the latest version of SuperSU (Make sure its the zip, not the apk) onto your phone/SD card. Boot into recovery, and install SuperSU through TWRP.
Congratz, you've succesfully rooted your X30
Tested and verified on mine. Sorry I could not include links, do not have enough posts. Just wanted to be of assistance!

This device (unfortunately) actually sort needs root to even feel at-home with. Which is sad, because the x5 Pro and x6 Pro weren't like that. I rooted them advanced purposes - not to get them to a decent state...

Help me please!
I stuck my phone in TWRP can you send me a copy of your recovery?

Question about Z5 Premium in 2018

How's the phone holding now?
i'm planning to get this one just for normal usage like streaming , chat, browsing, etc
and how's the heat during those kind of usage?
considering xperia design is totally to my liking, and the battery is above 3k mAh, kinda want to downgrade? into this phone from mi5, as the docomo dumps are quite cheap here
Thanks in advance !

I'm pretty happy with the phone. Heat is not so much of an issue.

if you are getting on good price ( 50% of the price since 2015) then go for it
Z5p is a gem!

How can I unlock bootloader and install TWRP, any guide?

i am also a user of z5P dual variant e6833, currently it has stock android 7.1.1, could anyone share the link of any post where i can find the list of all stable custom roms for z5p phone? unfortunately there is no linage rom available for this phone

After having this phone for 3 years, the first thing you will need to realize is stock battery even left in storage will have degraded past the stock level of battery, with little to no use over that time you'd be lucky to get even a stock unopened z5p with more than 60% of its original battery life.
The main issue with heat I've experienced has been during GPS use especially on warmer days.
The camera after unlocking and using non stock ROMs (even with DRM saved) as non stock ROMs don't use the DRM enhancements camera quality is noticeably less quality. So if you want to keep DRM quality you need to keep to stock roms, even custom stock ROMs need those enhancements enabled to be functional.
The overall speed, performance, battery life and functions of the phone are all good.
One thing to note also is latest official ROM is 7.1.2 so no Oreo, no project treble and no future proofing of the software. We also have a very, very quiet rom development.
You may enjoy the looks of Sony phones. But they don't support their hardware long enough for them to truely shine. We got 2 major ROM updates, with fixes in between that was what they reported as what they'll support.
This happened over a 16 month period. They dropped support for the phone as soon as Oreo came out, because they wanted everyone to upgrade to the ZX range.
Meaning a lot of us here that paid 1000+ dollars for their handset got less than 2 years of support from the manufacturer.
Companies like Samsung, Motorola and apple have put over 5 years support into most of their handsets. Software support is important due to app updates needing later OS versions to work. Meaning at some point the Z5 range will fall off the wagon even in terms of unofficial support.
Either way I hope you choose well a new device. Even though I like my phone, and will stand by my choice to purchase it, I would not recommend it to anyone else and urge them to find a better device with better software support.

New A3 2017 user: questions

Hello, i just got my A3 2017. I have a few questions, i hope you can answer them.
1) Android version is Oreo 8.0, security 1. december 2018. I want to know if they fixed the bootloop and crash when you use certain wifi's. And if there is any other major fault on this android version.
2) Is there any reason to downgrade to 7.0 or 6.0.1 on this phone ? I dont care about latest version, i just want the version that works best with no problems.
3) Can i use call recorder on this phone and how ? I will not root the phone (have my reasons) and i want only official roms
4) Anything i should know about this phone to get the best experience ?

To start, yes, all issues have been fixed. Now, with these requirements you're pretty much limited to oreo as you can't downgrade to a version with an older bootlader without rooting or using a custom recovery. The oldest build you can flash is the August 2018 one since it shares the same bootloader (Version 3) with the December 2018 one. Now call recording is pretty much dependent on CSC (Country Sales Code). So unless your phone came with a CSC that allows call recording, you'd have to switch to one that does have it, otherwise you'd have to root and flash a package that unlocks all CSC specific features on your existing rom. And lastly, yeah Exynos 7870 isn't that great anymore and even though samsung keeps using it in phones, the RAM and Storage of this phone really kill it, so unless you are going to do basic tasks with frequent maintenance, this phone won't really be your cup of tea.

Thank you for your replies,
Im happy that problems have been fixed and i can remain on 8.0 with no problems. Call recording is probably off but i can live with that. As for speed, there is no worries, i mostly just use it for calls and messages and occasionaly browse a webpage and use google maps. Coming from samsung s5 mini, this should be plenty fast.

I did some testing and using lab501 web browsing simulation with wifi on and screen on normal, battery lasted a whooping 1060 minutes. Coming from s5 mini which lasted about 300 minutes, u can understand how i feel. Also i tested always on screen: in 10.5 hours battery went down 3%. I am still deciding whether to use it or not. Its also a lot faster than my s5 mini, that was basicly the main reason i upgraded phone. s5 mini was otherwise perfect, but it was really slow.
I am wondering about some camera tips. I want to get the most out of camera. How to tweak it ?

Just wanted to say so far i am very happy with my phone. It is snappy enough (obviously with disabled animations and some apps), battery is great. Camera obviously could be better but thats a compromise you have to take. I wish it was a bit smaller, i have to use it with 2 hands often. Its very slippery, i use a "condom" for it but that is also slippery, which is absolutely stupid. I ordered like 6 new "condoms" of different looks and types and hope that 1 of them will make the phone as awesome to hold as s5 mini was. Remember s5 mini back cover is basicly rubber, that phone sticks to your hand ! I have some more questions.
1) how to get the most out of the camera, what settings ?
2) is it possible to remove the back cover and replace it with a rubbery back cover, like s5 mini had ? Or maybe buy some duct tape that would be less slippery and just stick it to the phone ?

Does anyone use this OS as their daily driver? What are your experiences and thoughts with the OS?

My Samsung A3 is almost 5 years old and I still use it as my daily driver, I'm thinking about flashing Lineage OS to the device and I'm wondering what anybody's experiences were with using the OS as their daily driver. I will use it mostly for calling, texting and journaling. I also listen to music quite frequently. I don't intend on installing any of the popular apps.

I've been using LineageOS and Cyanogenmod forever. It works wonderfully and I do anything I can with the stock OS and more.

I run LineageOS on my Samsung Galaxy S5 Duos and use it as my daily driver. It's running Lineage 17.1 which is Android 10 (18.1/11 has just become available too) - not bad for a phone launched in February 2014, which is now over 7 years ago!
If it wasn't for this phone only having 2GB of RAM onboard a lay person probably wouldn't notice much difference compared to a more modern mid range phone.
With LineageOS there's a lot less bloat so Storage, RAM, CPU Performance, and Battery Life are all improved.
I went the whole way and the phone is rooted as well and to be honest I wouldn't look back. I bought this phone all those years ago specifically to do this and it's really paid off.
But remember the LineageOS ROMs are specific for each phone. So the first thing to do is to find the support thread here for your particular model and read through it for points relative to your specific device.
I really like the freedom that LineageOS and Root gives me to do whatever I like with my phone, all while getting monthly updates and having a support thread of like minded users (well actually many of them are way more power users than me). Daily driver performance is excellent.
When I buy a new phone it will again be a model that can run LineageOS and be rooted. And I'll do this immediately after purchasing the device. These days that also makes some chinese model phones a good option as they often have a good hardware to price value ratio, but terrible support and updates. So it's possible to use this good value hardware but combined with an excellent LineageOS ROM, support, and updates instead.
Hope that helps

It's OK if you have A3 2016. But what's your motivation? Playing around? Avoiding Google spying? Impressing friends with new android version?

Thank you for the detailed response, and for reminding me to check the support thread for my model! I also noticed that the less popular Chinese model phones had better price to hardware ratios and the only thing stopping me was exactly what you mentioned, though I'm doing this to an A3 I'll probably consider buying something of the sort in the future for when I want an upgrade. From your response, Lineage is looking hopeful!
