It's good that the developer version of Android 5(Lollipop) has been released. For those of us who have no other contact with the world of computing but one device, it's not good for you to try working with the beta version.
Remember, this is a beta version and OTA releases are not a good thing right now because being able identify what doesn't work is the first thing that needs to be identified. The second needs to be asking "Why?" Third needs to be, "Is this issue device specific or a system problem?"
There needs to be a "Lollipop Developers Forum" where the developers can get together and hash over the code and deal with the problems. Don't get over eager. Pretty soon now (perhaps less than a month or a little more), stable releases will be here.
For now, we know that Lollipop is real and is being released to encourage us to get involved. That's what this forum is about, the first step-Finding out what the problems are with the developer version.
