I have bought a new Nokia 7 plus today and since I started setting up the new phone I noticed that the phone restarts abruptly by showing a dark blue screen for few seconds and then restarts automatically. It has happened 7-8 times within 4-5 hours.
I tried factory reset but still the problem persists.
My phone is running on Android 8.1 August 2018 security patch.
The problem is not associated with any specific app or charging. It just happens anytime.
I have read similar posts where others are facing similar sort of problems but no solution has been found. Please suggest what should I do regarding this.
