I have the Spigen Neo Hybrid case, it covers the buttons with a plastic button of its own that makes it super easy to press. Check it out.
I have the Spigen Neo Hybrid on mine and absolutely love it. The fit is perfect, despite some early amazon reviews saying the contrary.
Here are some images:
With the case on I can still charge wirelessly.
Ended up getting this one. It's cheap, have extra bumper protection for the corners, it has a transparent back (so I can eventually buy some Dbrand skins), and comes with one of their screen protectors.
I initially wanted the Neo Hybrid case, but a redditor gave a pretty bad review of it with a lot of detailed photos, so I decided it wasn't worth the extra $10 risk.
