I recently bought a Octa-core/2GB RAM from China supplier, the screen is good but some apps don't really work. I want to tune it a little, but I can't identify the type of Head Unit from its MCU. It says that has OS Android 8.1, but I doubt it also.
MCU version: T8.3.19-182-41-A46101-180716
System version: V9.3.1_20181030.153507_TW2-FD
