[Huawei P20 Lite Guides, News, & Discussion] srt54558:
Hello everyone,

After some time messing around and daily with the Android 13 Rom 'LeaOS', I experienced some issues and wanted to share the solutions with you all to save you some time.

1. No sound thru the headphone jack

-It may work already but the headphone icon is not showing in the status bar. To fix this I recommend using "System UI tuner" to activate it.

-If it doesn't work at all, go to the PHH settings, if available:

Open Settings app -> Open PHH treble settings -> Misc settings -> check "use alternate way to detect headsets" and "disable audio effects". Done. This should fix the problem.

2. No Bluetooth audio

- First method is to go to PHH settings again:

Open Settings app -> Open PHH treble settings -> Misc settings -> Bluetooth workarounds: none, Compability max aspect ratio: default, Force-disable A2DP offload: off. Check if those settings are set the same and reboot the device.

-If this doesn't work, go to the Android developer settings and check if "Bluetooth-A2DP-hardware-offload deactivated" is activated. In my case, it's already activated and grayed out.

-If this also doesn't do anything, messing around with the 'Bluetooth AVRCP-Version" and "Bluetooth MAP-Version" helped me. I've set the AVRCP version to 1.3 and the MAP version to default.

Don't forget to reboot after every change to apply it.

3. No mobile data problem

-If you don't have mobile data (internet with your sim card (no wifi)), I have a simple and fast solution:

Open Settings app -> Open PHH treble settings -> IMS features -> Click "Create IMS APN" and check "request ims network" and reboot after that.

-If it didn't work, go to the IMS settings again and click "Install IMS APK for NOT SUPPORTED".

This should fix it after a reboot.

4. Low graphics

If your phone has low graphics in some apps (e.g. settings app, volume control,...)

-go to phh settings -> misc and select "force fps" and select you're screen fps and resolution and reboot.

-if it doesn't work, go to the developer settings and open "Graphics driver settings". Now select a random app and select "graphics driver for system". Now open the app and it should work. If not reboot or try another app.

I'm not sure why it's like that and only some apps do something, but I think this is a solution. In my case "Aliucord" (A discord app mod) makes my whole system upgrade the graphics.

5. Bad performance

This problem is easy to fix:

If your phone is rooted, install a kernel tweaks magisk Module (I use "Yet another Kernel tweaker") and install the app "Kernel toolkit". In the kernel Toolkit app, go to the CPU tab and select the CPU scaling to "performance". Then tick the highest minimum CPU core speed for both the big and small cores. Then go to the developer settings of Android and select animations to 0.5x. Enabling 4x MSAA forcing may improve the performance, but I haven't seen a difference. Just do NOT disable HW overlays. This will destroy the performance completely. Also I got more performance on video playback (it was laggy sometimes) by disabling "settings for media transcoding" completely in developer settings.

!This drains the battery slightly more on usage!

And for the ram usage, go to each apps info, and open battery usage... Then click restrict. Do this to all apps you don't need to run in background. In the developer settings also go to "apps in standby mode" and restrict apps you don't need to run in background. You can also go to "Background checks" in the developer settings to turn off some Services you don't need too.

!Restricting those services will force stop them; you won't get notifications!

This is my Instruction with solutions for my problems. This is just from my knowledge. The display resolution thing is weird and I'm not sure if this is the right solution, but it works for me.

I hope this helps somehow 👍
