A. 1. Close background apps: Double-tap the home button (or swipe up from the bottom on newer models) and swipe up on apps to close them. This can free up resources for Snaptouch Camera. 2. Clear app cache: Go to Settings > General > iPhone Storage, find Snaptouch Camera, and tap 'Offload App'. Reinstall the app to clear any accumulated cache. 3. Restart your iPhone: A restart can help improve overall performance.

B. 4. Reduce photo resolution: If the app allows, try reducing the resolution of photos being processed to improve performance.
