How do I switch off safe mode on my rca voyager tablet

To get your tablet out of "Safe Mode" try the following.

Restart your device by holding the power button, then tap Power off.
Tap OK to confirm.
Power the device on.
Your tablet should now be out of safe mode.

If the device is still in safe mode use one of the following methods.

To uninstall the last application you installed:

Go into the "Apps" menu and tap on "Settings".
Next tap on the app you installed just before the problem started and then tap on "Uninstall".
Restart your device.

NOTE: This one is a last resort option. You would want to back up any personal data (addressbook, photos, vids, etc.,) before attempting this, as all would be cleared off your phone.

As last resort, you can perform a factory data reset:

Go into the "Apps menu" and tap on "Settings", and then tap "Backup & reset".
Next tap on "Factory Data Reset", and then on "Reset Tablet".
And finally tap "Erase Everything" to format your tablet back to factory default configuration.

AGAIN, I cannot stress enough, that this last one should only be used as a last resort, as it will remove anything you have put on the tablet.
