OK, this is REALLY starting to tick me off. Past couple of days every time I go to install an app I get this 'XXXXX could not be installed. Free up some space and try again.' Total space 5.59Gb. Available 3.36Gb (internal storage) 7.40Gb total available 6.37Gb external. Yes I have cleared the caches etc but STILL can't put any apps on, ideas please.
