Operating System: Android 8.1.0 GT06_V1.0.2 Model: alps tb8163p3_64_bsp Processor: ARM MT8163 @ 1.50 GHz 1 Processor, 4 Cores Memory: 1.0 GB Internal Storage: 2.00GB + Expanded Storage 64.00GB (Micro SD) Black screen can occur if you have RA installed on external storage by means of adopted storage. If you are using external storage as internal to expand disk space, RA needs to be on NAND despite it actually working by itself on OTG store. I don't know the technicality behind this reasoning. I understand the basic logic in am start to launch an activity but nothing ever seems to happen after opening RA on adopted storage.
