• Poor Network Connectivity: Check if your SIM card is properly inserted. Ensure you are within network coverage. Try restarting your device. Verify your network settings (Settings > Network & internet > Mobile network).
• Battery Draining Quickly: Reduce screen brightness, disable unused features like Wi-Fi, Bluetooth, and GPS when not needed. Close background apps. Check battery usage in Settings > Battery to identify power-hungry apps.
• Fingerprint/Face Unlock Not Working: Ensure your fingers are clean and dry for fingerprint unlock. For face unlock, ensure adequate lighting and that your face is clearly visible to the front camera. Re-register your fingerprint or face data if necessary.
