Forgetting your smartphone password is a situation that almost every user has encountered.

Unlike “pure” Android, additional steps may be required here, and some functions (for example Find My Device) depend on the firmware version and the region of sale of the device.

  • 🔋 Battery charge level (minimum 30%, otherwise the phone may turn off during the process).
  • 📡 Availability of a backup copy of your data (if a reset is unavoidable).
