How does Samsung Note4 forcibly shut down?

Regarding your inquiry, if the phone can't be turned off normally because of the crash, you can remove the battery of the phone and try to turn it on again.

If it can be started normally, please refer to the following:

1. Check whether the third-party incompatible software is installed in the phone. Please delete this kind of software.

2. Back up telephone data (phone book, text messages, pictures, etc. ) and restore the phone to the factory settings (Settings-Reset-Restore Factory Settings).

If the phone still crashes after being reset, there may be something wrong with the phone system or hardware. It is recommended to send the mobile phone to the nearest Samsung service center for inspection and maintenance. Please click the following link to consult the service center:.
