All modern smartphones have a proximity sensor on them that turns the screen off to save battery on the phone. Usually this issue is linked to a phone case or screen protector. If there's nothing that would visibly cause this, you may need to book this in for repair.
You can do this either by calling us on 789 or 0345 6000 789 or by logging into your online account here and by going into Plans + Devices > Phone Repair.
We can make sure this is sorted for you as soon as possible. Let me know if you've booked this.
