With the new update, Opera Mini, is working good. Im not having crashes in my Lumia 520 with Cyan and Update 1.
One thing Im noticing now is: before, Opera Mini was in my phone language (Spanish) but now is all in English.
Improve the download manager because when saving an image, it really does not save it, to save photos I have to open the downloaded photo right after the download and save it from here.
Thats all I think... the Opera Mini redesign for WP can wait a little.
