I was hoping to increase the external storage on my phone so I could use it as my music device also. At that point in time, I only had 16 GB of music on my laptop. I only transferred about 3-4 GB on to the SD card. Unfortunately, the phone and the card could not work together.
None since it caused my phone issues
Delayed my phone's responses; Sometimes caused the phone to shut off in the middle of a process(texting, phone call, etc.) Other times my laptop would read the card, other times it didn't get a read at all; May have been the adapter when in use for the laptop
