M31S-Automatic restart issue

[00MVSV00]

In that popup it asks goto out of bounds and the buttons are cancel and ok

First when i turned on phone after showing the company name Samsung it shows like this called as out of bounds.It even restarts automatically when I am doing my work in between like chatting or calling extra..........

So could you please solve the issues
