So some newer devices have been shipped with different components from the older ones and while everything works fine on recent miui versions, most custom roms have issues. So I'm creating this thread to document all the issues caused by these new components and any solutions to them in one thread. Please reply if you have any other issues caused by the new hardware or any solutions to them.
Fingerprint
Description:
Option to add fingerprints doesn't appear even after setting pin, pattern or password on non miui based roms.
/data folder contains goodix folder with contents on miui.
Cause:
Some devices have a new fingerprint sensor manufactured by Goodix which is not yet supported by non miui based roms.
Solutions:
miui and any miui based roms such as xiaomi.eu should still work fine.
The newest build of Santosh's CM has a fingerprint patch available that will fix it.
Wait for CM to add support for the new hardware to its source code.
Battery
Description:
Battery is stuck at either -2% or 50%.
TWRP does not show battery percentage at all or constantly shows 50%.
Cause:
Possibly new battery controller hardware, by the looks of it the issue is related to the kernel, older CM kernel builds seem fine and so do newer miui builds however any rom using a new CM kernel build or based off it has the issue.
Solutions:
Fix was added to CM source code so the problem should be solved on all newer roms and kernels based on it now.
Flashing Radon 1.9 or above will fix it on any CM source based roms.
miui and other miui based roms such as xiaomi.eu should be fine.
Santosh's CM13 plust the camera fix works.
Mokee works fine.
Unofficial Ressurrection Remix works fine up until the 06/08 build.
This is the patch applied to Radon to fix the bug.
If you know of any other issues caused by newer hardware or solutions please tell me so that I can add it to this thread.[/QUOTE]
If possible, Can you also provide information about how to identify different components without changing roms?
Thank you.

Added for the fingerprint sensor, using TWRP is still probably the easiest way to check for the battery bug.

The sensor of fingerprints with aida64, it is possible to identify.
The battery only if flash the TWRP, for the present.
Santhosh's CM13 battery bug is gone if you flash his camera fix.

Ok cool I'll add it to the post and test it out if I get a chance.
I hear of that Mokee is using Xiaomi device tree, I guess that is why it don't has the "-2% or 50%" issue...

The camera fix works only with Santosh's CM13, not with other CM/AOSP roms
the new kernel Radon V1.8 by Umang96 does not fix the battery problem

I would expect it to work on all Santosh based roms, the camera fix must have modified something that flashing a new kernel overwrites, if we can figure out what the camera fix changes we might be able to get a fix for all roms.

Well that would explain it, but at least we have roms without the bugs, that should help figure out the problem.
any working custom kernels for -2% or 50% battery bug?

as far as i know AIDA64 is not a good way to see your fingerprint sensor it shows fpc102x for me but i have a goodix sensor, in fact i think the other ones with fpc sensors have a fpc 1035 not a 102x. i think a good was would be checking kernel log you should see the module name or checking data partition ( if you have root) or system/etc/firmware if you dont (i'm not sure about the second one but i can see some goodixfp data there)
just saying maybe it saves someone from lots and lots of confusion as i had when i bought my device
The new Radon kernel doesn't have the -2%/50% battery bug!
For the cm13 based roms : http://forum.xda-developers.com/showthread.php?p=68012485 and few posts under there is a test version for MIUI rom

Yep just flashed official RR with this kernel and no battery bug!
Yes, there is just the lack of the support ou goodix fp and it will be perfect !

Now there are, just updated the post.
Radon V1.9 Kernel does not cause the battery bug .......
Radon V1.9 Kernel does not cause the battery bug on "MIUI 8 by Xiaomi.eu 6.7.28 | Beta".
I got a test version from @Umang96 and successfully got below 50% battery level.
Any custom kernel working with goodfix fp ??

Hello,
I have a Xiaomi Redmi 2 running cm13. Model no-2014818.
Its front camera is not working.There is no option in the Camera app to access the front camera??
Is it a hardware problem or a software issue.
Can anyone please figure out a solution to this??
Many Many thanks in advance.

go to settings
installed apps
find camera app
clear data and caches!
if this dosent work change the rom!
of flash the rom again(clean flash)
last but not the least
use the miui stable rom
I have cleared the cache and data but still it's not working.I have also flashed the stock miui stable but the front camera is not working.
It once and only once worked when I flashed the HTC remix rom but after that no longer even in the HTC remix rom. Is there still a solution???

Which custom rom you're facing this issue? Have you installed a nougat custom rom and not installed marshmallow firmware maybe?
i tried resurection remix rom,dot os rom. while installing those roms i simply wiped the cache,dalvik cache,system and flashed the rom and gapps... everything was perfect except the camera error.
i dont know about the marshmallow firmware.could you please give me the link for installation of that marshmallow firmware

my friend just pull the battery out when the device is running and then put it back and turn the device on againe this problem happened to me and I searched for solution for very long time and finally I find the solution by Coincidence hhhhh
I'm having the same problem with RR since about 4 months. Can't use my rear camera. It is being detected but can't be used (tried any camera app). When I installed RR, it worked. I have this error since changing my display.
Try to Google it, there are some unofficial fixes out there but I'm not sure if they're really working. I would regard an official fix, but this will have to wait I think.
Such bug has already been fixed with each ROMs' respective latest builds.
Mine too I got a distorted camera but whenever I capture it captures normally, I haven't tried using other camera apps
I've got the same problem
im using footej camera now and it's ok
running stable miui 11 xiaomi.eu latest build. when i open camera this error sometimes appears. the weird part is that it happens just sometimes and just in build in miui camera. other apps work ok and never had similar problem with third party camera app or social apps on stock or custom roms. does anybody know how to fix it ? i already tried clean installing several times. this problem first started after i unlocked bl and flashed miui.eu build
