Anbernic RG552 AOSP 9.0 Beta #15 (Bugfixes, better performance, 16:9 HDMI output and QoL improvements)

DESCRIPTION

This time around I bring you several bugfixes, a handful of performance improvements, proper 16:9 HDMI output without black bars, dismiss-able MicroSD card notifications and a new toggle to force portrait-only apps into landscape mode.

How to install: Download and install 7zip on your system, download all attached files (SDFlash if you have a >= 4GB MicroSD card ready, MaskROM otherwise) into the same folder, extract the file ending with .001 by right-clicking it and choosing "7-Zip -> Extract Here" and finally open README.txt for further instructions.

Things to note when updating from a previous build: If you previously had Google Apps installed, please make sure you re-install them after the update to avoid crashes!

For those needing the Google Play Store: Reboot into TWRP and install the latest OpenGapps ARM64 9.0 Pico bundle! (I suggest you finish the first-time setup with WiFi disabled... things move so much faster if you do!)

For those needing root: Magisk is included out of box and only needs to be activated on first boot. A WiFi connection is required for the initial Magisk activation.

Things to note when using the "Fast" sleep mode: WiFi & BT adapters can get stuck in a disabled state when put to sleep without going through their proper early-suspend routines (which is what the "Fast" sleep mode omits to enter sleep faster). If this happens to you, please reboot your device to re-initialize your WiFi & BT adapters, or even better, only use "Fast" sleep mode if you don't plan to use WiFi & BT for a while.
