Very glitchy. Watching a video from a friend will cut out and then you can't do anything because you'll see the line at the bottom of the page (that's used to fast forward or rewind the video that is no longer playing) over your phones home page, like you still have to exit the video that crashed on you. This has happened many times. Trying to scroll up on a chat or simply just tap it to keep your phone from locking and the page automatically scrolls down instead. It's incredibly frustrating.
