I'm having this issue w my 3 week old One. Besides the purple red hue, I now have an issue where if I'm in a dark room such as my bedroom either at night, or in morn if I press power button the home and back buttons light, but screen stays black. I can hit button 10x and screen may flash for split second but won't turn on. If I turn room light on everything works fine.also if I disable auto brightness it also seems to work.
I am within my return window since I got it during holidays but build wise the phone is ok, and I've heard of others having camera, speaker, sensor issues w return phones. The phone was built in aug, I bought it from vz store. Should I try to exchange, or would it just be better to send to HTC for repairs?.
Ant suggestions to fix sensor?, I can wait for camera fix but I do use phone in dark.
