Open apps is very VERY laggy and buggy with one ui 2.0. Please fix this in the official version.
As a beta tester please report beta issues properly. Look under "reporting bugs":
I have the option to get the beta. For the second time. But I'm just gonna wait for the official update. I keep seeing issues I wouldn't be able to fix. I can't flash anything I don't own a computer. And I refuse to hard reset my phone.
