I have a LG Optimus with Android Gingerbread. I've bought a SD card, which works fine, but my phone says I'm running low on memory. I've transferred every app and every file to the SD card, but still I'm running low on memory. There are some files from old apps which can't be transferred. The message is this: "This folder contains hidden maps or files". Do you know a way to delete them?
Just erase the data from programs you don't use, like Google+
