Erratic or intermittent flash card storage: I bought two 32gb class 10 "house brand" microSD cards from Micro Center. They test fine, and store anything but jpegs from the phone's camera with no problems. Doesn't seem to matter whether I format them in the phone or in plugged into my PC's USB. File checks, etc in the PC always are OK. The camera in my Galaxy S2 would take pictures and display them, but I could not send them of access them via USB from my PC. They would soon become impossible to display. I could see file names and file sizes, but no images. I was told it was a problem with the card, but no test I ran, nor substituting an identical card would change the behavior. As said above, other stuff including jpegs put on the card(s) via USB were OK and long-lasting. I think I had saved a few jpegs received in the phone as attachments, and they were OK also. Card and phone checks were all OK, including backup and restore operations. Changed to a Galaxy S5 and had the very same camera behavior on those cards. Did the checks and backup/restore operations again and no improvement in ability of the phone to take and store photos on the Micro Center cards. Searched the web many times and consulted with Sprint tech support several times. Nothing seeming relevant on the web, and the not-so-bright tech support folk online and in stores said the card is bad, but no test can find a fault or fix a corrupted photo (even though file sizes etc seem OK). Discovered that the Samsung Galaxy S5 can accept bigger microSD cards (128gb max), so got a Samsung class 10 64gb microSDXC "EVO" card and populated it from a backup of the smaller card. The Samsung card seems to have no problem with photos taken by the S5's camera, but cannot display older corrupt photos from the S2's camera that were in the backup file and thus on the new Samsung card. Tests via my PC of the Samsung card show no problem as was the case for the earlier cards. Nothing I can find or do seems to show why the Samsung card is "better" and OK. Did I forget the spunkwater and magic words needed to use brand-X cards in a Samsung Galaxy phone? Chuck -------------- next part -------------- An HTML attachment was scrubbed...
