I would recommend using Wi-Fi Transfer, or whatever it's called... The built in system in your Qslide Apps, and backing up everything you can to your computer that way, or backup app info (such as SwiftKey) to its respective cloud system if it supports it, then doing a factory reset.
If it doesn't work after that, try to get it replaced, it should still be within your grace period.
