My iPhone freeze with grey screen and then restart alone. Thereafter the Wifi is unavailable, I have to complete restart manually to be able to use the Wifi. I already restart my network/internet settings but the trouble is still there.
Hi there Turco911,
It sounds like your screen is going gray then turns off on its own, and you have to restart it manually to get the wifi to work again. I would backup your device to iTunes, then restore it as new and verify that it works.
How to erase your iOS device and then set it up as a new device or restore it from backups
If it does, then restore your backup to either verify it still works and the software just needed reinstalled, or isolate the issue to the backup file itself.
If when restored as new the issue persists I would seek service for your phone:
Thank you for using Apple Support Communities, all the best!
