Random Reboots, Wi-Fi hanging, and Delay in Notifications (Other issues, too)

[anon(5325135)]

Recently, I got a Nokia Lumia 1520 on Christmas Eve this past December.

The device started off well with no issues at all until recently. I say it started around late January

*Delay in Notifications (Facebook and Twitter for example, over an hour delay)
*Random Reboots
*Wi-Fi hanging (won't connect and does not switch off unless I reboot phone)
*Screen is really dark at times
*Registers a tap instead of a swipe

These are the most common issues I've had recently. Is there a fix around this? I did not hard reset my device the day I received the phone.

Maybe you should try hard-resetting it now. Couldn't make it worse.

That's actually what I was trying to avoid. Haha. Yeah, I feel like that might be the only option. Settings should be backing up to OneDrive, correct?
