I just got an update for Opera Mini, this time the app did not crash. The UI is a little too simple though, its like one of the earlier version of Opera Mini for android devices. But it loads page faster than Nokia's Xpress Browser. And pages looks better compared to UC Browser express mode. Keep up the good work... *** three star for now :drunk:

Windows Phone 8.1 Dev Preview Lumia Black

Mine is also crashing upon start up, can only get up the loading icon.. Im using a lumia 720 with Windows Phone 8.1 Dev Preview with Lumia Black, tried restarting phone and still the same.

I tried switching off wifi and use data and it still not opening.
