How to delete an app I can't delete, or disable, the app YGPS,
on my Android tablet; and I didn't install it.
It's a preinstalled app(bloatware) so follow this guide and you should be able to remove it(NOTE:Requires rooting your phone which means voiding your warranty and beside rooting no way to remove them exists): https://www.androidpit.com/how-to-uninstall-preinstalled-android-apps#delete-preinstalled
