Question

Is it true 4gb m2 memory cards are unstable and make your phone work slower?

Answer 1

The card itself will not slow down your phone any noticeable amount.What will slow down the phone are the kind of files, and and the size of files you have on the card. For instance, loading an mp3 file is far less tasking than a movie. Another example is trying to load a file your phone can't use. That will definitely slow down the phone.

Answer 2

as long as I experienced with my phone, yes it is. It do makes your phone performance slower. I recommend a 2GB for the optimum performance. Is it a sony ericsson ? if it is, then it depends on the series. but I mostly found out that 2GB works for optimal speeds.
