SanDisk is now claiming responsibility for Samsung Galaxy S3 issues that users complained are killing memory cards and randomly leaving users with dead batteries.
According to SanDisk a newly documented problem that effectively fried SanDisk micro-SD cards was in fact a manufacturing default.
After searching for a comment on the issue, SanDisk informed The Register that:
“SanDisk has been made aware of potential product issues involving a very small percentage of its 32GB and 64GB SanDisk Mobile Ultra micro SD cards. Under certain circumstances the cards may lock up and the card becomes inaccessible. The issue has been identified and a manufacturing fix has already been put in place. SanDisk stands behind its products and any customer who experiences this issue with the microSD cards is asked to contact the SanDisk support center for a resolution immediately.”
The problem, which was only recently documented by Android Central forum user Paulnptld had been causing users’ Micro-SD cards to effectively become unusable after a few months’ time without warning. After that initial post, other users experiencing the same problem as well as battery issues that they thought could be traced back to their use of SanDisk’s cards chimed in:
“Initially reported by Samsung Galaxy S3 users – the symptom is that the card repeatedly remounts, causing the host device to rescan it and hence hammer the battery. A colleague was showing me logs of this happening 200 times a day. I’ve experienced two such failures with SanDisk Ultra SDHC 32GB Class 10 cards being used in GoPro Hero3 cameras.”
Users looking to have their defective micro-SD cards replaced will have to mail their card back after receiving a return authorization number from SanDisk Support.
As device manufactures move to compete with each other in a smartphone market that favors the thinnest, and most affordable devices, micro-SD cards have become a common way of passing on the cost of media storage to users. This isn’t unique to smartphones either — slots for micro-SD cards routinely show up on tablets as well, making them one of the few near universal storage methods for mobile computing.
Since micro-SD cards have increased in storage capacity and decreased significantly in cost over the past six years, it isn’t uncommon to purchase a smartphone with only 8GB of storage and a micro-SD card slot to enable users to add as much as 64GB of additional storage.
