Resolution Note (fix version 2022.3.15f1):
Input device listener processes the callback on UI thread, instead of the Main thread; this was incompatible with GameActivity setup, where Java looper is not present on Unity's main thread. This change fixed the bug where DualShock4 controller was not recognised after being disconnected and reconnected to certain Android devices.
