How to move passwords and speed buttons from PC to Android?
Import/Export does'n has such option, Opera Link is a one big laugh.
How can I move my remembered passwords and speed links from PC Opera to Android Opera?
With root access you can copy your Speed Dial (favorites.db) from the PC Opera profile manually to your phone (/data/data/com.opera.browser/app_opera/). I guess that even if you move the passwords file (Login Data) it won't work but you may try it. Only do that if you understand what you're doing.
