Lumia 1020 :: Keys Won't Light Up

So I recently just replaced my Lumia 1020 with another 1020 because it wasn't able to make or receive phone calls. When it did, it connected to 2G and wouldn't switch back to LTE. I just got my new 1020 yesterday but now the keys on the screen won't like up unless I cover the sensor new the ear piece. I don't want to have to do that every time I use my phone and I'd rather not do a hard reset since my other phone is still resetting as I type this (going on 17 hours).
