You can unblock your Samsung A22 by performing a factory reset, which will erase all data on the device. To do this, turn off the device, then press and hold the volume up and power buttons at the same time until the device logo appears. Use the volume buttons to navigate to the "Wipe data/factory reset" option, then press the power button to select it. Confirm the action by selecting "Yes," then reboot your device. This should unblock your phone, but remember that all data will be lost.
