My device power cannot be turned off. What should I do?

Last Update Date : Apr 19. 2018

It happens when there is a problem with SW or power button.
The phone may not be turned on or off even after you turned off the power. It is due to the problem with SW. Upgrade it with the latest SW.
You can upgrade more comfortably by wireless. If you do not use unlimited data plan, you may pay for the use of data. I recommend you updating in a WiFi zone. 


  • FOTA : Settings > Device info > Software update > Update
