Maybe...
I love my Bolt and don't have most of the issues that others have or I don't let the them bother me so maybe I don't notice like they do. That being said, a lot of the gripes are legitimate. Stuff like rebooting and other things that literally don't work the way their supposed to (sorry, can't think of anything else right now, crispy) are legitimate gripes. Then again if you think how young the technology is (Android, LTE, the Bolt) overall and how much amazingness that is packed into this phone you are going to have some kinks. Living on the cutting edge... not that all phones don't have their issues anyway, old and new.
Also, even of the first one was a disaster, better updates will come. Remember we are not even 3 months deep.
