Hello, Following a firmware update I lost my Polaris Office which i used quite frequently. I found online the .apk for it and manually installed the app. However the app looks like it's loaded, it appears on my applications list, and on my home screen, but when i try and launch a document, I just get a message to say Polaris has stopped. I have since bought a different app for editing documents as i could not get Polaris to work. However when i go to the applications list to un-install it, all options (cache, force stop, un-install etc) are all greyed out. It shows the full install and data size (6.33mb), but I can't find anyway to un-install the app. Can anyone tell me a) How I can un-install it and b)How or where I can get Polaris office back again? (it's supposedly part of the pre-installed apps) The strange thing is, I updated my wifes SGS2 using the same firmware file as I had used, and her phone didn't lose the Polaris office app? The firmware is ICS 4.0.3, on XWLP7 (baseband XXLPS) if this helps? Thanks. -Stu.
