Except for non working hotspot as mentioned I have no media volume control. Everything plays at max volume and volume slider does nothing. Also Google Pay does not work.

EDIT: Got help in telegram. For GPay you need to set up magisk and saftynet fix module. I skipped magisk first time since I didn't care for root but it's important just for hiding features.
Volume control worked on second try and is supposed to work so maybe I screwed something up first time or just some random failure.

Everything is a bit big on screen and looks slight off with default settings. To fix/workaround go to developer options and change "Smallest width" from 360 to 392.

I'm really interested in this, my biggest regret swapping to Samsung has been the bloat and battery life.
Anyone have any better battery life using GSI? Or worse? How is the battery compared to stock?
TIA.


Battery life is nice so far. Loving PE.

Only Universal SafetyNet Fix ? No MagiskHide Props ?
Because I can't run "props" of MagiskHide I don't know why...

edit : actually fix here https://forum.xda-developers.com/t/...p-edits-and-more-v6-1-2.3789228/post-86780359

Can pass SafetyNet with just the Universal SafetyNet Fix but my phone is still recognized as rooted. Don't know how to fix this.

It was nice to have stock Android on my S21 but too many bugs on GSIs I gave up. Too bad thank you for your job anyway.
