S5's SD card constantly corrupting

In April 2016, I upgraded from a Galaxy S4 to an S5. I didn't want to upgrade any further for fear of not having an SD card. A few months ago (after being sick and tired of my phone's memory being full) I bought 2 SanDisk SD cards (both 64GB) from Amazon. When I received them, I formatted one, put in in my phone and off I went. I moved apps over, some photos etc. It worked perfectly fine for a month or so before it said that it was corrupted. I looked online for help and learned how to run a test on it using the card reader and my laptop. There was no reviving it so I reformatted it and returned it to Amazon for a replacement.

I have since put in the other 64GB SD card and it's been the same experience. Works great for a few days, then corrupts. I have safely removed it, re-inserted it and then it works again for a few days. Then it'll corrupt again. This has happened many, many times over the last several weeks.

Is it something I am doing wrong? Is it the phone? I am so sick of not having room on my phone to download new apps, store photos etc. Luckily, my photos instantly upload to 2 different clouds so I have not lost photos but this is a huge annoyance!!!

Can someone please help? Thanks.

Wanted to come back and reply. I purchased a recommended Samsung Pro Class 10, 64GB, U3 microsd card and my phone has been working perfectly for nearly a week now.

I have unmounted, mounted, taken battery out, restarted and completely powered down with this card with absolutely no problems. I'm guessing it was an incompatibility issue with the SanDisk card.

Thanks for your input.

If both cards came from the same place and same batch, I'd guess it's the SD card. They can, in my experience, easily become an issue. If you purchased that card through Amazon, and had the same issue with the other, I imagine they will allow you to return that one as well.

I haven't looked into an SD card for my S5, but something I learned when looking for an SD card for my Dashcam, some devices reject certain cards. While SanDisk is popular, I'd do a bit of research about various card brands and what has and hasn't worked.

I have doubts that it's the SD cards but I am certainly not ruling it out. I had the 2 cards that I received from Amazon for about a month before I actually used them. By the time I tried them both it had been some time. By the time I had sent it back and received a replacement it had been 6 weeks or so.

The only thing I can think to try is to boot up the device in Safe Mode with the SD card in and see what comes up.

Can you provide a link to the SD card you purchased?

These are the ones I purchased.

I am not sure I know how to reboot in Safe Mode. Would you be so kind to provide me with instructions or a link?
