HTC confirms Sense 5 coming to existing phones, some features limited to HTC One
 

HTC didn't have much to say about its Sense 5 UI coming to existing devices when it introduced it alongside its new One handset, but it's now gotten a bit more talkative. In a post on Facebook, and confirmed to us independently, HTC says that global variants of the HTC One X, One X+, One S and Butterfly will all be getting an update to the new interface "in the next few months," although specifics remain light beyond that for the time being. The company does note, however, that not all devices will support all the features offered by Sense 5, as some of those features make use of hardware specific to the new HTC One.
