Good news: Android 16 GSI from Google has booted with BPF backports from LineageOS Gerrit, and for sure there will be LineageOS 23 ROMs when LineageOS 23 source is ready to use

Launcher animations and window transition animations looks smooth, statusbar animations looks laggy

Though, there won't be official LineageOS 23 and up, unless if anyone come up to resolve the hassle of converting 69 Android.mk files to Android.bp, I'm too lazy to do it anyways

LineageOS 22.2 recovery for Mi8937_4_19 from unofficial build

Highlights:
- Added USB Mass Storage feature, an alternative to DriveDroid, which allows you to expose ISO/IMG images or eMMC partitions to PC via USB (https://review.lineageos.org/q/topic:22.2-recovery-ums)
- Disabled ZIP verification

Smash mirror is dead
Added Telegram mirror

Hope this would be the last LineageOS 22.2 build, as android security releases has became quarterly, and hopefully LineageOS 23.0 will be available to use in really few months

Thanks to someone on LineageOS Gerrit, 5.10 BPF backport chain is up and booted on our devices

(it's fortunate that we have stable k4.19)

About mainline: now 3D accelerated graphics works on msm8937/40 too

Status of mainline ROM:
- Audio: Basically working with some small issues, only on devices which I've made config for (ugg&ugglite)
- Battery: ✅ (some devices charges slower though)
- Bluetooth: ✅
- Buttons: ✅
- Camera: Barely any sensors would be supported & I don't have such device to test yet
- Display: Partially working
- Fingerprint: Don't hope about it
- GPS: No hope for now
- Graphics: ✅ (have some glitches, though)
- Hardware codecs: No idea about how to do yet
- IR: Works on ugg&ugglite, No support for the rest yet
- Notification LED: Android side changes pending, not hard
- RIL: No support in Android yet (importing the ModemManager based HAL would be a pain in the ass)
- SD card: ✅
- Sensors: I don't know how for now
- Touchscreen: ✅
- Touchscreen buttons: Done for only ugg and ugglite for now
- USB: ✅
- Vibration: Works for only devices with GPIO vibrator
- WiFi: ✅

(this project may never finish... mostly just for fun)
