My friend’s phone is stuck on a screen with a white background with a grey apple logo in the middle, it periodically turns itself on and off but never shows anything but the screen mentioned before. I have tried updating it but it doesn’t have enough space.

Hold on the power button to force power it off.Connect phone to iTunes, and then from phone Summary, restore iPhone to fix the phone stuck on the screen.If you don’t want to lose data on the phone, use EelPhone iOS System Repair tool to fix iPhone stuck on screen, which can fix iOS system problems without losing data.
