They need to advertise, plain and simple. And they need to release a phone that works on every carrier.
Kind of like Samsung did.
When's the last time you saw an HTC commercial? Was it the one for the HTC ONE X "O look, you can take a picture while shooting video!"
Cuz, y'know, personally I hate that I can't take a picture while shooting video... really HTC? That's your killer feature? *yawn*
And hey... while we are at it... how about we tell all our customers we are going to update their phones by certain dates... and miss those dates either entirely or by 6 months?
