Opera Mini unable to start
The latest version of Opera Mini has a problem on Android 5.0. it said that To run Opera Mini you need more space. Try removing some apps or clearing app data. But I can install other apps without clearing something. Please fix it, I have to using firefox or chrome instead right now.
Do you previously installed any Opera Mini before on that Handset?? Maybe its a problem of you system file. if you previously installed Opera Mini then Uninstall & if you have a rooted phone then Go to System/Data/Data/com.opera.mini.native using ES File Explorer. Then delete the "com.opera.mini.native" folder then restart & try to reinstall Opera Mini.
And you don't have rooted device just try to Reset (Restore Factory) to your handset.
Hope, it will works.
My phone is not rooted, I have been using it since Mini 16, and it can't finish updating today, I delete it, reinstall it, use tools cleaning my phone, sadly it does not work. I don't want to restore factory, all kinds of apps need to redownload. I'd rather wait for the next version or maybe change a Web browser.
