Title says it all. So when I realise my mistake, I put the SD card that was in before back. This card has had nothing done to it, just removed. When I turned it back on my home launcher is gone and so are almost all my apps. I reboot. Same. Over time, my app drawer is getting bigger with my apps but I'm getting low space warnings. I haven't had those for ages. Is it rebuilding the Dalvik and will be ok soon or is something bollocksed? Help please.
