I noticed last night that my screen is not rotating into landscape mode. I'm nearly positive it is a hardware issue, because I could get it to rotate briefly by tapping it on something, but then it would immediately go back. I bought it at Best Buy on launch day. Is it too late to take it back there? I would much rather deal with them than Sprint or HTC support. I've never had to return a phone for anything before, so I'm just curious where I should start. Thanks in advance for any help you can give!
