I have Polaris Office installed on my HTC Sense 6, but I cannot delete or find it on my installed apps, Play Store, and even Device Administrators. Though, I can run the app and use it. How am I going to delete it?

how can we change the input & displaying of dates in Polaris Office to UK format? The devices are set in Settings/System/Date and Time/Select date format to UK style (dd/mm/yyyy). The default within Polaris seems to be yyyy/mm/dd. Other android users wrongly think this is UK format . You can change the date format of cells to be any of the following: - yyyy/mm/dd (default) - mm/dd/yyyy (US format) - mm/dd - dd-month-yy - dd-month - month-yy - month-yy - month dd, yyyy - dd month yyyy (almost UK format) Ideally we need the correct UK date format dd/mm/yy or dd/mm/yyyy as this is already in our source files. We cannot change this (only the format of the cells) as users will be working on files generated from MySQL in MS Access and outputted to .xlsx This seems an oversight on Polaris part, but I don't see much 'chatter' about it around the web, so should we notify Polaris of this?

My mobile phone has Polaris Office default installed on it, but when I open some files I cannot see special characters, like "á", "à", "ç" etc., there is just a space character when it would have one of those special characters...
