I have two problems:
Quite a lot of the time I try to connect use Wi-Fi my phone decides to stop being connected. This happens in every location I try.
My iPhone cannot decide what the time is. It will always be 12 - 1:30 am with my phone
Edit: Another problem. Occasionally the screen decides to stop working for a couple of seconds
iPhone 5c, iOS 9.3.2, Blue
Try these standard troubleshooting steps.
Reset: hold down the Home and Power buttons until you see the Apple logo (10-20 seconds).
If this doesn't help, you might need to Restore your iPhone.

Regarding Wi-Fi try

2) Reset Network Settings: Settings > General > Reset > Reset Network Settings. Rejoin the Network again.
