Top critical review
Didn't last long.
on December 5, 2015
This card has failed after about 18 months. It was used in two cell phones, both of which now say it's damaged. This occurred suddenly after cycling my phone on and off. The card can be read in Windows, so I could get my data off, but it is not writable, and, hence, can't be reformatted.
Samsung has no section on their web site for microSD cards. I had to initiate a warranty claim on something else. They directed me to a third party service company. I gave them the information requested, but I'm not optimistic I'll hear anything useful back.
UPDATE: the warranty servicer actually did contact me and initiate an RMA. However, I explained that I couldn't just send them an uneraseable card with all my private data on it, but they insist on getting the card to service the warranty. So, effectively, the card has no warranty. A replacement card certainly isn't worth the identity theft risk. I can get a new card for $10.
Samsung should consider that bad support on a cheap item can (will) cost them sales on an expensive item. Oh well . . .
