Hey @NFP ,
happy to try to help you with this. Is the phone rebooting when you are using a particular app or action on the phone? Can you please check if auto-restart is enabled on the phone?
You can do this by following these steps:
- Go to the settings menu, then go into the Backup and reset submenu.
- Under the Device management tab, click on Auto restart.
In regard to the SD card, are you able to tell me what model are you using? Have you tried to use a different one?
Are these third-party apps or it is also happening with default/embedded ones? Can you place the phone in Safe mode and monitor it for at least two hours to see if the same thing happens?
To turn it on in Safe mode, first turn the phone off > When you turn it back on, press and hold the Volume Down button until it starts up > The phone will indicate when it is in Safe mode. If it is not restarting in Safe mode, then it is a third party application causing this, so you will need to turn your phone back on normally and disable recently downloaded apps one by one and determine which one is the cause of this issue.
In regard to the SD card, have you tried to use a different brand?
