7. Troubleshooting
| Issue | Solution |
|---|---|
| Device does not power on. | Ensure the device is fully charged. Connect to a power source and wait a few minutes before attempting to power on again. |
| Slow charging or device not recognized by computer. | Use the original Type-C cable provided. Ensure the power adapter is compatible (5V/2A recommended). Try a different USB port on your computer. |
| Applications crashing or freezing. | Restart the device. Clear the cache of the problematic app (Settings > Apps > [App Name] > Storage & cache > Clear cache). If issues persist, uninstall and reinstall the app. |
| YouTube app server error. | If the pre-installed YouTube app encounters server errors, try accessing YouTube through a web browser or consider installing an alternative YouTube client from the Play Store. |
| MicroSD card not detected. | Ensure the microSD card is properly inserted. The device supports cards up to 1TB. Some specific manufacturers or card types might have compatibility issues. Try reinserting or using a different card. |
| Device takes a long time to boot up. | This can sometimes occur. Ensure no applications are running in the background that might slow down startup. A factory reset (Settings > System > Reset options > Erase all data (factory reset)) can resolve persistent slowness, but will delete all user data. |
