Hey guys. I'm thinking of getting a 2nd hand HTC One. Problem is, i'm a little worried that i might get the purple tint issue with the camera over time once i buy it. I need to know how many are really affected by this issue that i don't think HTC has any answers right now? It'd be better if i had a checklist of what to double-check before i make my purchase? ie. heating the phone up real good and check the camera(purple tint issue) Much thanks.
