Hey. My Samsung Galaxy S4 has stopped connecting to wifi recently. It's listing my home wifi as "out of range" (even though I'm in the house in front of the router). I've tried connecting it other places (shopping centres, libraries, my workplace etc), but getting the same problem. I know that my wifi annentae isn't totally broken as I can get connect partially at times. Bluetooth is also intermittent, mostly off, but pings to life for a few seconds every hour or so. I've tried a full factory reset and took it into Samsung shop. However, theres a tiny scratch on the screen and Samsung won't fix it under warranty because of it. I can, however, connect to wifi in my local pub (good excuse for a pint, but not very practical!). Not sure if this is part of the problem. I've searched everywhere for a solution, but no one, as yet can help me. Any ideas folks??
