This is not a new thing, as I have been dealing with this issue for people long before there was Android. The issue here, is people that constantly feel the need to stuff their device with more and more apps, and then complain about being low on memory and/or poor performance of the device. I will get asked to fix this issue time and time again, and the answer is ALWAYS the same, don't stuff it full. Think of your device as a truck. The more you are carrying in it, the less capacity you have left and the slower your performance will get. This rule applies to all operating systems (Android, iOS, Windows, etc) The S2 is a great device and does come with a generous amount of memory, but it is not unlimited. If you do not use the app on a daily or weekly basis, then consider not keeping it on your device. Get yourself a backup app (ie Titanium Backup etc) and back the app up to external storge (sd card, your PC etc), or just download the app from the play store when needed (Google Play remembers apps you have paid for so you don't have to buy them again). Get yourself an external SD card, they are rather cheap to get for an 8 or 16gig, and store your pictures and music on that instead of the phones storage.
