A. 1. Adjust the touch screen settings: Open PPSSPP, go to Settings > Controls > Touch Control, and adjust the layout to better fit your screen. You can drag the buttons to reposition them. 2. Calibrate your touchscreen: Some devices have a calibration option in Settings > Display. Calibrating your touchscreen can help improve touch accuracy.

B. 3. Use an external controller: If touch input remains an issue, consider using a Bluetooth controller that is compatible with PPSSPP for a more reliable gaming experience.
