Hey there, I replaced my Screen and everything works fine. After a while (sometimes an hour, sometimes after a day), the iPhone crashes and reboots. After the reboot, the Wifi Button is greyed out. I then have to reboot the iPhone several times until the wifi will work again. Ideas for a cause? Kind regards Janos
Something must have gone wrong when you replaced the screen. I would suggest that you go back through this guide and double check your work. You may have damaged a flex or connector so look closely, preferably with magnification.
