Is there a way to prevent uninstall without root? Currently, it seems that you can just disable device admin and then uninstall with play store. I remember cerberus would challenge you for a password deactivating device admin. Are there similar protections in avast anti theft? Thanks!
You can set a pin code on it.
Her is some information and there is a lot more to be found in FAQ there.
