Yea I agree, bad release. They should know to never do a x.0 release. I was going to do my own roll of 5.11 until I saw it rolling out to other phones.
For the most part I haven't had a problem and I am pretty pleased with 5.0.
The only real problem I've had is the phone spontaneously reboots. And it doesnt happen often. But to be fair I had that before Lollipop too so can't blame that.
