Sorry to tell you, but it seems your phone is damaging the SD Cards (or you have very bad luck and got two damaged cards). That icon shows up when the file is corrupted or the card is damaged. You can try to recover the pictures if you can still read the files on a computer, but if the file is corrupted, chances are it's gone

When I had phones with SD cards (not for a few years now), I learned this critical rule: do not allow your camera to save images directly to the SD card. Save them to RAM and then move them later if you wish.

If you save directly to the SD card, you WILL encounter corrupt files. Maybe just one or two occasionally, maybe most of them. But it WILL happen.

Also, SD cards have speed ratings ( https://www.sdcard.org/consumers/speed/ ) . You should make certain that you purchase cards with a speed rating that is compatible with the device with which you are using it.

yup, I had several issues with SD cards and Samsung phones in the past, so after the Note 3, I stopped using them and learned my lesson. Now I only use them for movies and files I already have elsewhere.
