Not sure. My phone research involves asking friends what they think of their phones then reading the online feedback. I got the Bionic when it hit the shelves before there was really any reviews or ratings. My first mistake. I'll just keep slapping this one around and cycling the power for now. I',m not in a rush to spend hundreds of dollars on a new phone right now. I don't have much use for a phone outside of making calls, texting, and surfing the net, so whatever they do outside of that is pretty worthless to me. My only requirements are that they have decent data speed, good coverage, a decent camera, high res for watching videos, and in call volume that's loud and clear for folks like me that spent too much time around noisy rc planes, dirt bikes, race cars and worked in loud machine shops for twenty years. lol
