I have a Droid X and wanted a bigger SD card so I bought a 8g card to replace my 2g. I did the transfer and it slowed my phone, it kept locking up, and I eventually had to take it out a put back my 2g SD.
Before I made the switch I backed everything up onto the desktop of my laptop and as soon as I put in the new card that was the first thing I did was to replace all the stuff from there.
Did I do something wrong? Is the card too big? Bad or wrong Micro SD card? any idea or help appreciated.
