On my F6 I keep getting APP update failures due to incorrect insufficient storage warnings. I have just over 150 mbs left and app updates one 10th the size cause this failure. Some work arounds have been clearing the system cache, using ap2sd, rebooting the phone and deleting the app and doing a clean install. This sucks. I do know that Rooting and deleting the bloatware is the answer, but that's not quite for me. If there's space available, why can't it be used?
