Please let me know how your trip to T-Mobile went.
My wife and I bought a Samsung Note 2 last month and both of us bought and have installed a Sandisk 32GB Class 10 Micro SD.
Last week, within a day of each other, we started encountering the following EVERYTIME we use our phones:
SD CARD UNEXPECTEDLY REMOVED
REMOVING SD CARD
PREPARING SD CARD
It happens when we wake it up from being asleep, and randomly during using it.
I can't find any reason why it is doing this.
We have saved everything off of the SD Micro Cards, and reformatted, yet the same issue persist - have you found a solution yet?
