I did all of this – when I searched for updates, it says I’m using latest version. But I still have message “No available device administrator”. What else can I do? I did a factory reset aa instructed by my carrier tech department. Also, Play Store has message that it’s stopped working and I can’t get into Play Store at all.
Do you see below option on your device?
Settings > Security > DEVICE ADMINISTRATION > Device Administrator > “Android Device Manager” (Allow Android Device Manager to lock or erase a lost device)
