I have an iPhone 5 and just installed the new iOS 8 update, however I am suffering from a couple of problems:
I can't connect to any Wi-Fi and in Settings I cannot even get the push button to move to turn on Wi-Fi.
When I start to write a text and turn my phone side ways the screen goes black for several seconds then when it comes back only a few letters on the keyboard will work however most will not. If I tilt my phone to the upright position it works.
How can I fix these problems?
