3 SD cards ruined by Galaxy S3
My experience, Samsung Galaxy S III:
Team 32 Gb card - after a month, 'SD card removed' (while still in the device), no access to music or other files on the card. Removed, into a Win7 machine - can't complete a full format, totally busted. Maybe a bad card, RMA for a new card.
A couple of months - SAME THING.
OK, Team cards maybe low quality, replace with a SanDisk. Guess what, took a couple of months, but that cards has also failed, also can't be regognized by phone, can't be formatted in Win7.
Samsung sez maybe I have a 'corrupt file'. Sigh. This is a real problem, prehaps low frequency, perhaps a range of manufacture batches - I don't know. But a real problem and requiring a real response...
