Picked up this memory card at a great price on a gold box deal. Reputable name, fast card. However, after several months of trying to get my phone to work with the card, formatted it, partitioned it. &#34;mounted&#34; the card, &#34;unmounted the card,&#34; all to no avail.  I realized that this memory card is not compatible with my Samsung SGH-T769 (Galaxy S 4G). No need to get frustrated and try a Sandisk &#34;Ultra&#34; 32GB Class 10 card in the phone. I replaced this card with a &#34;plain&#34; Sandisk 32GB Class 4 card in my phone, it was immediately recognized, formatted and mounted by the Samsung phone.YMMV
