So have been Bionic for 2 days. Found a bug in the Browser...while on a web page, if you press the bottom left menu button, you find a button for "Windows." Press it and you'll have a list of open windows with a big red button to close that window.....well, touch that red button and instead of deleting that window you just open it again....I tried many times, but no good. I've downloaded Dolphin browser and I kind of like it so far. Tried Firefox and disliked it. Had horrible battery life yesterday while on 4G. Today it's on 3G, and I spent quite some time on WiFi, and battery is holding good so far last 4 hours; yesterday battery was near zero in 5 hours with 4G on.
