LineageOS is a free, community built, aftermarket firmware distribution of Android 6.0 (Marshmallow), 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. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review.

For VoLTE we need the kernel source.

A HUUUGE THANKS for you to fix those GPS issue, and also to make the native dt2w working!

Also, video playback looks fine on mine, played a few downloaded videos and nothing weird happened (those are .mp4)

[FIX] Low Mic volume/gain issue

I'm going to share a fix for low mic volume/gain issue. The Redmi 4A is suffering from bad mic issues, not during a phone call, but in other apps e.g. voice recorder (or videos recorded with de device, if the not working feature will be fixed in the future). It's not a hardware issue but software issue:

Root is required.

Navigate to the root directory of the phone:
Root/system/etc/
Then look for a file named "audio_platform_info.xml" with text editor of your choice .
Now go to the bottom of the file you will see </acdb_ids> , you need to add the below line before/above that </acdb_ids>
Click and add this line:

<device name ="SND_DEVICE_IN_VOICE_DMIC" acdb_id = "100"/>

Now just save the file.
Reboot the device now.

Incredible update. :good:

I can't express my gratefulness with words.

I don't know what magic you guys are doing but this ROM runs more smoothly than the official ROM :laugh: and I now understand why they are not releasing the kernel for this phone because everyone will switch to LineageOS.

gr8 job. btw why dont we have seperate xda forum?

We do have a separate forum for Redmi 4A.

New fix: Solving the problem with the quality of sound recording in video/voice rec.

-root required

1. open file:
/system/etc/audio_platform_info.xml

Under <acdb_ids> add this:
<device name="SND_DEVICE_IN_HANDSET_MIC" acdb_id="1"/>
<device name="SND_DEVICE_IN_HANDSET_STEREO_DMIC" acdb_id="1"/>

2. open file:
/system/etc/mixer_paths_qrd_sku2.xml

search for:
<path name="handset-mic">
<path name="adc1" />

There are two lines with DEC1 / DEC2 - delete them and replace it with:
<ctl name="DEC1 Volume" value="96" />
<ctl name="DEC2 Volume" value="96" />

3. Restart phone
