Review on 📷 Gigastone 256GB Micro SD Card: Gaming Plus, Nintendo-Switch, 100MB/s, 4K Video, Action Camera, GoPro, Dash Cam by Nikith Brewster

These 128GB microSD cards were said to be "Android compatible" and according to reviews they should work on a Kindle Fire 8 tablet. The second day after I put them in my Kindle and Android phone (LG Power X), it turned out that the Kindle was "incompatible" and "ejected unexpectedly" according to the tablet when I woke up. All of my apps that were moved to the SD card were unusable on my Kindle. I had to put the SD card back into the computer, format it and download it again to get it working. Then the same the next day. Complete nonsense. And now it has started doing the same for what I put in my phone! I spent several hours making sure all my apps and photos/videos were copied from the old SD card to my phone before inserting the new one and I'm glad I did. Otherwise I would have lost my files. If you are still interested in purchasing this product, make sure to back up your files to the cloud or your computer before using it. Attention buyers, attention users.
