[Miscellaneous Android Development] M.A.P:
​

LineageOS is a free, community built, aftermarket firmware distribution of Android 8.1 (OREO), which is designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway. All the source code for LineageOS is available in the LineageOS Github repo.

* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.

Whats Not Working

:

* No Music Key Function

* VoLTE is not working

* HDR in camera is not working

* Notification LED not working, if it is connected to PC or Wall during boot the light will stay on, In that case reboot with cable unplugged so that atleast the LED wont be distracting

* Selinux is Permissive, will fix it after few builds by collecting logs and fixing denials

Workarounds

:

* Use Jio4GVoice for VoLTE calling ( Assuming that you are on jio network otherwise for calls it'll automatically change to 2G/3G )

* Use open Camera or Camera MX for HDR

Instructions :

Download the latest build, treble TWRP and gapps(optional)

Reboot to recovery

Wipe System, Vendor, Data, Cache and Dalvik Cache

Flash the latest build

Reboot

Reporting Bugs

DO NOT Report bugs if you're running a custom kernel or you installed Xposed

Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)

If it is a random reboot, grab /sys/fs/pstore/console-ramoops and /sys/fs/pstore/dmesg-ramoops-0. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless). Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues. Any bug not reported in the bug report format below may be ignored.
