Constantly crashes if type too fast...pointer disappears, page bounces to another section then back again, sometimes deleting text just entered! Went from a Galaxy Note to a Galaxy J7. Didn't have these issues with the Note...so, to be fair, not sure if its the app or my new device. Help!...Update: Now, app causes device to not work properly. Get this message: "System UI not responding". App causes device to freeze. Uninstalled app, device went back to normal.
