Hi there

From the text of your post, I gather this is a new issue that you have just experienced for the first time. Is that right?

If so, what changes have you made to the phone recently? If you have downloaded a new app, regardless of what it is, perhaps try to delete it and see if that helps. What were you doing when the restart occurred?

Welcome to iMore. Which iOS are you running? iOS 7 was known for this, but was later fix with updates.

I don't know why it is happening. It could be caused by a faulty setting, weak wireless signal, a rogue app, etcetera. You can try any of the following to try to fix the issue.

1. Go to Settings - General - Reset and then tap on "Reset All Settings".

2. Go to Settings - General - Reset and then tap on "Reset Network Settings".

3. Call your wireless provider to see if they can troubleshoot from their end.

4. As a LAST RESORT, restore your device and set it up as new.
