Just want to know if anyone is experiencing reduced speed of file transfer via USB when using app2sd? It can goes down to as slow as 300KB/s. My card is class 10 and can transfer at > 10MB/s when used directly in my PC via an adapter. I suspect the phone is constantly accessing the card in the data partition but don't expect the slowdown to be that significant. BTW, I'm using VR12 so only data partition is on sdcard.
