I upgraded to Jelly Bean when it came available and immediately started noticing problems. The phone became sluggish in general but most notably the keyboard lagged to the point where texting became problematic. I was unable to use the gallery app - it would open but pictures either wouldn't load or I couldn't scroll through them. The camera app also wouldn't scroll through my pictures. The web browser was sluggish even on a strong wi-fi connection. I did a factory reset twice and lost a ton of information in the process, in hopes the reset would clear things up. I ended up going to the store and the rep said he would have a new phone overnighted - which by the way, they gave me a used, sorry, a "certified like-new replacement" phone, not a new one.
Now that I have my replacement I'm reluctant to upgrade this one to Jelly Bean if I'm going to continue having problems. Are/were these just an isolated problem, perhaps something in the phone itself and not the software, or are these widespread issues that will hopefully be addressed? I've read on forums all over that people are complaining of battery drain but I didn't have that issue, just the sluggishness and the inability to access my pics.
