I did a warranty return for my phone. There was a hardware based problem with the rear speaker. This is the first phone I've had that was rooted and had a custom rom, and it took no time at all to bring it back to stock with Odin. No issues with the warranty.

FWIW, a lot of roms have wifi calling. I use it, too.
