It doesn't add a lot of new features, just a few, and it's completely unestable on my iPad Air and on my iPhone 5s
More than a beta it seems an alpha
I assume your not a developer and using this beta on your daily device. It's surprising people complain about the obvious things which is clearly written down when you accept the terms and conditions before you instal the beta.
I'm not a developer and updated my phone with ios 8 beta and been running it since with no major bugs which haven't mentioned on these threads.
I'm guessing your trolling or kidding as it seems alot of android fanboys been doing lately since iOS 8 was announced,
