Can a full SD card cause a phone to lag? I have a 16g that I took from my OG Droid....sorry but I thought the 8g you get with a D2 was insulting when you get a 16g with a D1...anyway. I have around 128mb of free space on it and am noticing my phone starting to lag. Is it the full card or something else? I am posed to buy a 32g but want to know if this is the cause before I do.
