Please follow steps below for troubleshooting:
- Enable Location function in Settings
- Go to a wide place where you can make your tablet receive clear satellite signal for about 5-10 minutes
- Access Safe Mode by long pressing power key > tapping and holding Power Off > tapping OK
If your tablet works well in Safe Mode, there may be some 3rd apps that cause malfunction
Please reboot your tablet and check again if it works well - Backup your data and perform factory data reset
