Troubleshooting
Common Issues and Solutions
- Network Connectivity Issues: If the phone does not reconnect to the network after losing service (e.g., after exiting a tunnel), try restarting the device. If the issue persists, verify SIM card installation and contact your service provider.
- Slow Response/UI Lag: The device may experience occasional delays in button response or user interface navigation. Ensure no excessive applications are running in the background. A restart can often resolve temporary performance issues.
- WhatsApp Usage Difficulties: Navigating WhatsApp with arrow keys can be challenging. For certain actions like agreeing to terms, you may need to experiment with button combinations (e.g., holding the middle button and pressing up) or linking WhatsApp to a PC for easier management. Prolonged video calls may cause the device to heat up.
- Phone Not Powering On: Ensure the battery is correctly installed and charged. Connect the phone to its charger and attempt to power it on.
