I fond a cheap, decent clear phone case for my 525. Turns out the 520 and 525 are the same phone as far as physical cases and covers are concerned.
Next up: a real screen protector. Matte, preferably. These reflections are quite a bit more annoying than what I am used to, due to the presence of an air gap and the lack of polarizers. A high display brightness can only do so much.
It's kind of difficult to press the buttons, since the case covers them, but I suspect double-tap to wake and virtual shutter buttons will prove useful.
EDIT: This might be the worst case I've used yet - I have removed it, but it wont be going to the can yet. It got annoying.
