Hi. I have a Samsung Galaxy Gio for some years now and problem I got is my 4 years old brother trying to access it.
What I have tried now:
1.Set a password > Ended up in permanently lock because his random password input. Need to reformat firmware.
2.Hide > Wake up late because I not hear the alarm.
3.Give him a cheap tablet > He thrown it at the floor after about 1 year, and said he want to play Galaxy Note.
Is there any program or something that can make me lock the phone without any lock.(Just put password again and again but not have to enter the email & password of google account because 90% ended up in cannot unlock.)
