According to your description, I suggest you:

1. It is recommended to go to Settings-Application Manager-All -s Health-Clear Data/Clear Default Settings.

2. Do you have mobile phone security guard software or some third-party software programs installed in your mobile phone? If so, try uninstalling it.

3. Back up your important information and try to reset your phone (Settings-General-Reset-Restore factory settings).

If the problem still exists, it may be a problem with the mobile phone system or hardware. Please go to the nearby Samsung service center for inspection and maintenance. The address of the service center is .samsung.com/support/servicelocations.asp.
