HTC ONE..Don't use the HTC hard shell....
well i am a bit peeved, my ONE came yesterday, beautiful device, popped it into the official Hard case I bought in advance, was a happy camper.
Took it out of the case last night to have a "naked" play if you like without the case, and noticed two marks on the ally back. One in the dead centre lines up with a moulding lump inside the red top cap of the case, the other to the right top corner.
It is the case that has done this, and im really peed off.
I have emailed HTC and await a response.
Anyone else have this case? check the back of the phone at the top if you do.....
