offline charging is working but after the % shows and display goes off when i try to see how much have charged the display does not come up pressing power button so holding it the system starts booting , i used the firmware that came with my SM-T220 out of the box SM-T220_XAR_T220XXU1AVB2 A11 with february security patch as base , could be the vendor the problem which one did you used and are you sure that customAP with this gsi can't be made with a12 as base <> ? maybe is the framework overlay used in /system/product/framework is from a11 stock rom or something else im going to try to make one with last a12 FW with october security patch and see if i can boot and solves the offline charge stuff also i need mtp

EDIT/UPDATE :

Build Number : T220XXS1BVJ2
Android version : S(Android 12)
Release Date : 2022-12-02
Security patch level : 2022-10-01

1.PE + / PE Extended Can boot with A12 Vendor but File System will locked itself (can't install or update any apps due to source code >> must waiting for next release but with A11 vendor it works well.)

✓2.Offline-charging will break Samsung "Warranty Bit" Stop Freezing System State ( Can't reboot with Power-off/on button except press and hold Power+ Vol down)

✓ 2.1 It will only show % battery charging only when you insert cable with power source not by press power btn.

1. Yes im getting AVC denial we have to find out how to set selinux to permissive mode and set the rom as userdebug i have tried adding to the kernel command line androidboot.selinux=permissive buildvariant=userdebug still enforcing after boot the only way is compiling the kernel with support to disable selinux in

https://github.com/DevZillion/andro...ifixx/blob/main/security/selinux/Makefile#L20 from true to false

PS : if we get permissive selinux ViperFX will work too and maybe fix TWRP touch

Samsung insert coding against using permissive mode at boot time in the kernel. you can't changes it with app.

please add power management.

 

[ozmage]

please add power management.

like frequency scaling governors ? powersave performance schedutil are already and default to last one using smartpack kernel manager they can be changed i use powersave a lot if u mean thermald is also present when you are on stock rom but in gsi is missing.

we need something else too force disable encryption in the vendor fstab making vendor image r/w and kept it that way
