I don't get why htc would prevent this. Every other phone available including at least the Nexus4, note2, S3, and S4 allow this. Why is the option not available with the htc one? A little ridiculous for them to lock it. Not that I would want to use anything else at the moment but I would like to know that I can. Just the way I switched the keyboard to swiftkey i want to be able to switch the text app to gosms if they ever fix the black bar of death at the bottom.
