Keyboard and switch access compatibility testing and fixes

[tech-master33]

Summary

Ensure andrdscren works correctly alongside Android Switch Access and Bluetooth keyboards.

Why it matters

Some blind users also have motor disabilities and cannot use a touchscreen. They rely on switch devices or keyboards. The screen reader must not intercept key events that Switch Access needs, and must announce focus changes triggered by keyboard navigation.

What needs doing

1. Enable andrdscren and Switch Access simultaneously on a test device
2. Navigate every screen using a keyboard or switch only
3. File any focus announcement gaps or key event conflicts as sub-issues here
4. Fix each conflict — likely in the AccessibilityService key event handler

Where to start

Enable both services in Settings → Accessibility, then navigate the app drawer and a text input field. Report anything that gets stuck or goes unannounced.
