So, since the new ROM update 2.17.x I’ve had some random freezes while using Opera Mini 4. One thing I had issues doing was trying to uninstall the existing installation. If you want to remove the current OM 4 install go into Java > Applications > Menu > Remove All. This will remove all OM midlets and you can reinstall again. I’ve just did it and will see how OM is performing now. Hopefully, this will clear out the recent crashings.
