Didn't fix wifi searching issue or wifi speed sometimes extremely slow for me, also notice when typing if incoming call the screen will freeze sometimes and I can't pick up the phone ..... If caller hang up then everything back to normal.....

Using iOS 8.1 beta, wifi still have issues as well as keyboard sometimes still disappear. Some small tweak photo is now same as iOS 7. In setting going into iCloud and photo will force close. Still buggy hopefully next beta will include more fixes.
