Similar situation here using an Alcatel One Touch Fire.

In my case hapened two things: a) The phone suddenly restarted or b) The phone get frozen

With browser, facebook, twitter.

Is possible that this issues has been reported to be fixed in the next release?

I found that random operating errors, etc., got fixed when I reset the phone. It was a pain since I had to redo everything, but some persistent issues disappeared after that. To do that, select Settings -> Device Information -> More Information-> Reset Phone.

Be aware that you will lose everything you've added since you've gotten the phone. All email, calendar, etc., information will be erased and all apps you downloaded will have to be down loaded again. For me, The reset still didn't fix the update issue, but it made things world that didn't work before.

eBay US ZTE Open - Twitter app crashes are almost reproducible. They happen at random on both the FxOS build that ships with the device and when flashed to the latest 1.2 preview. I can pretty much always get it to crash with either version of the OS by

1. Opening the tweet box to post a tweet
2. Attaching a picture.

If I want to tweet a picture, I have to

1. Take the picture and save it in the Gallery
2. Open the gallery app and share the picture on Twitter
3. Add the tweet text and press the Tweet button.

It still usually crashes, but sometimes it manages to post the tweet before the crash.

I haven't had any other app crash on me. At some point I want to try reproducing this with the emulator.
