If anyone else has this problem (like me) just follow the instructions on the video below. The guy's legit.
As for the blurry graphics, go to Developer Settings and turn on the "Force 4x MSAA", although beware, because depending on the device it could worsen your performance.
EDIT: 4xMSAA didn't do shit after all. Just change graphics settings in Engine.ini on "Scale" (0 value is for your screen's native resolution, 2 is 1444p I think? 1 must be either 720p or 1080)
For more settings just search on Reddit, you'll see the first thread, very helpful.
