- Device not powering on: Ensure the battery is charged. Connect to a charger and wait a few minutes before attempting to power on again.
- Poor battery life: Close unused apps, reduce screen brightness, disable unnecessary features (e.g., GPS, Bluetooth, Wi-Fi when not in use), and check for background app activity in battery settings.
- Camera not working: Restart the camera app or the device. Clear the camera app's cache and data (Settings > Apps > Camera > Storage). Ensure the software is up to date.
- Connectivity issues (Wi-Fi/5G): Toggle Wi-Fi or Mobile Data off and on. Restart the device. For Wi-Fi, try forgetting the network and reconnecting. For 5G, ensure you are in an area with 5G coverage and your plan supports it.
- Fingerprint/Facial Recognition not working: Ensure the sensor/camera is clean and free from obstructions. Re-register your fingerprints or face in the security settings.
