A. 1. Close background applications: Go to your device's settings, find 'Apps', and close any unnecessary applications running in the background to free up resources. 2. Clear cache: Navigate to 'Settings' > 'Apps' > 'Overmortal' > 'Storage' and tap on 'Clear Cache'. This can help improve performance by removing temporary files that may be causing lag.

B. 3. Lower graphics settings: If the game has an option for graphics settings, lower them to reduce the load on your device's hardware.
