The Samsung android table I got for my kid has a "Guest Account" feature that lets anyone in without a password. Kind of defeating the point of the password feature that keeps a 7 year old kid out at bedtime.
so I ran:
adb shell settings put global guest_user_enabled 0
with a USB cable attached and it worked. Now the guest account is gone. But all the 7 year old has to do is go into setting and do a factory reset and that will go back to
adb shell settings put global guest_user_enabled 1
Right?
How do I win this password war? I'm older. I have to win.
