Worked with the NVIDIA SHIELD Tube TV (2019)! My NVIDIA SHIELD TV storage space started running low and so the venture to get a Micro SD Card in there to expand it. I first bought the Samsung (MB-ME32GA/AM) 32GB 95MB/s (U1) microSDHC EVO one, but as soon as I popped it in I got the notice that the card was too slow and I should be looking for a U1 card. I ejected, put it back in but kept getting it. So thinking that card might not be compatible, I found this one. Searching for the SHIELD TV yielded results that other people had success using it with their SHIELD TV's. Ended up buying the 64GB version, so I pop it in and guess what? Same thing happened. So annoying. But at least this time I did get the option to reformat it which I didn't with the other card. But after I kept doing it, I kept getting that same response. The only other thing I thought to try was to reboot the SHIELD TV with the card in it. So that's what I did, and this time it worked! So if you guys are running into that issue with your SHIELD TV, try unplugging it to reboot and that should do the trick. Hope NVIDIA fixes that bug, cause that was annoying. I expect the Samsung card is fine too since I didn't try rebooting with that in it. Now this SanDisk one is working great so far. Happy with my purchase (now that I got it working).
