If you have also encountered the above problem, the hard grid method is as follows:
1. Press and hold the power and volume down buttons simultaneously until the black screen is turned off;
2. Press and hold the power, Bixby and volume up keys to enter Recovery mode immediately after powering off.
Use the volume keys to navigate to Factory data reset, then click the power button to confirm, wait for completion and reboot the device.
