Android touchscreen barely responsive — how to enable USB file transfer / ADB debugging with minimal taps?
I have an OPPO A53 (CPH2127, ColorOS/Android) with a cracked screen. The touchscreen is mostly unresponsive -- it works intermittently, maybe one successful tap every so often.
I managed to unlock the device once, but the screen keeps failing before I can finish setting things up. I don't have a USB OTG mouse/keyboard available right now.
What I'm trying to do:
Switch the USB connection mode from "Charging/MIDI" to "File Transfer (MTP)" so Windows can see the storage -- normally this needs 2-3 taps (expand USB notification -> tap File Transfer).
Is there any way to do either of these:
Via adb/fastboot commands alone, without touching the screen, given the phone is already unlocked but USB mode is stuck on "MIDI function"?
Any workaround appreciated -- I just need to recover personal files (photos/documents) before the screen fails completely.
