I'm currently experiencing a problem that rears its ugly head once every few months. My S2 is a 16 Gb model with a 32 Gb Micro SD card on board. Both these memory areas are approximately half full. My apps auto update and usually do so without any problem. Currently a couple of apps go through the process but fail to finish, with the pop-up "Insufficient Storage Space". I clean the cache on a weekly basis and, at times like this, I do it again and retry the update with the same result. Any tips, anyone?
