my gut feeling is that redirects and reloads are in fact a memory issue of the phone. available > ram getting tight with many apps in the background competing, and not enough room for mini to > > expand websites, that are getting fatter and fatter.
Yes, that's memory management of Android. But UC-Browser takes 100M vs 70M of Opera-Mini, still working nice at 460M device (Android 4.4)!
It uses persistent service-threads, what could use Opera's developers, if they really care of real users.
