I'm experiencing a restart issue with iPhone 15 Pro Max (USA variant) using in India that appears even after a full format. There is no such as water or drop damage.
The iPhone works fine ***but after switch off and power on it again it restart again and again in 2-3 minutes loop for few days but at one moment it will work alright.***
