My daughter uses four digits number as screen lock of her phone (Xiaomi Redmi 3S) but one day phone wrote "incorrect". She did not change it so she cannot forget it. It happened three times yet. In twice issues she unlocked it through GMail account associated with her phone but in last one it is not allowed to do. Questions:
- Is there some way to unlock by GMail account again?
- What we prevent to do to avoid self-locking in future?
