  2. Click the Configuration button (the RetroArch icon).
  3. Go to Controls.
  4. Select any item from Port 1 Controls to Port 5 Controls.
  5. Select any button configuration to remap.

Research direction

Start by reproducing the crash on Android 9 using RetroArch 1.8.5/532fd88, following the listed Controls and Port 1–5 remapping steps, with and without a Bluetooth controller. Done means remapping succeeds without a crash for any core and the tested control ports.
