Can anybody help updated to the new update yesterday since then my phone has been playing up with its WiFi and cellular not working properly. I have checked the service status for my WiFi and cellular and nothing seems to be wrong there. If I go on chrome or an app they take ages to load things where as before the update it would only take a couple seconds. Also it keeps asking me to sign in to my cellular by putting my number in and I have done that a couple of times but it keeps on happening. Any ideas on how to fix it? Thanks in advance.
