Re: how do you factory reset an android tablet
If it won't log in, you can't do it from the Settings, so you'd have to go into recovery mode and reset it from there. However, this method depends on which tablet model you're using. Could you provide us with that info, please? Usually it's a combination of keys before powering on the device.
In most models, also, entering enough wrong log in information enough times will automatically wipe out the device.
Just remember, factory reset means ALL DATA is lost. Documents, pictures, videos, music, downloads... all gone.
