Hey @SurajJadhav1. Do you have any apps running when your phone restarts? Please place your phone in Safe Mode and see if the issue persists. This will disable third party apps and if your phone is fine during this, it indicates an app is causing the issue and I recommend deleting them one by one until you find the culprit. To do this, restart your phone but whilst it's powering up, keep the 'Volume Down' button held until you reach the home screen. If done correctly, Safe Mode will be displayed in the bottom left corner. To exit safe Mode, restart your phone as normal.
