Spyware and tracking apps can cause occasional restarts and shutdowns on your Android devices. But, if you know that your device software is stable and recently updated, then your phone has spyware software installed.
Any unstable or third-party apps can also cause reboots to the system. You can reset your device after backing up all device data for once to check whether the issue is solved or not.
