BTW, did a factory reset after upgrade to make sure of a clean install (have heard anecdotally that this may greatly increase optimization and speed). Got a resting android with a "No Command" message and was afraid I had bricked my first phone, but a hard shutdown and restart everything was fine.
Pure Edition here. I did not get the soak test. I just upgraded over 4.4.4. No reset or anything and I haven't had a single issue at all. I like the changes. Only thing I had to do was reset the "trusted devices" to keep my phone unlocked.
Very happy so far.
Im fine with waiting for the revised update since the beta versions are chock full of bugs. Id still love to know if 5.0s Android Auto enables USB Mass Storage. ......
