After doing a bunch of reading and following the topics in the forums the wife and I took the plunge and picked up our new Maxx HD phones at our local Verizon store yesterday. We did the 9.18.79 update while in the store and everything ran perfectly thereafter. No lag, no stutter and no crashes. WOW What an awesome phone! I'm upgrading from (can you believe it) a first gen HTC Incredible, the wife from an Incredible 2. The only issue I've noticed is that quite a few of the old apps wouldn't work on the Jellybean. It's all good though, non of them I couldn't live without. Bubble levels, a compass and such are nice but not critical. The on board calender app is really lackluster but that is what Google Play is for, right? Just wanted to post a positive here. We're both super happy with our Maxx HD despite it's minor flaws and quirks.
