Verdict

The Fix: Unbranded Allwinner systems running older Android layers often block background touch emulation injection. To bypass this restriction, the unit must be rooted via standard tools (such as Magisk), and an Allwinner-compatible input plugin must be installed manually to grant the remote software system-level touch permissions. Essential Safety Warning Regarding MCU Files

A simple restart or a factory reset within the Android settings can sometimes refresh the communication between the MCU and the CPU.
