When I bought this a year ago, I had problems with it working properly in my Sprint E4GT (Galaxy SII).  The card kept waking up the phone to be read, over and over.  SanDisk acknowledged this problem in &#34;some&#34; android devices and shipped me a new card once I returned this one to them.  The new card still had the same problem, so I gave up.  The card is fast, and I got a good deal on the price, so I am pretty disappointed about it.
