I tried moving the micro SD (SanDisk) from an older Fire to the one I just bought, but got a message that it wasn't compatible. So I ordered a new one and got the same message. What really annoys me is the lack of information--there is nothing with any of the Micro SDs to tell you which ones you can use with a Fire. Why not? Why don't they say clearly suitable/not suitable for Fires? Or why isn't there at least a list of the suitable ones, or a list of specifications to look for? I've never needed an SD reader and so can't check the formatting in a computer.
Can anyone tell me how I know before paying for something and trying to install it only to find it's no good?
Um, I have SanDisk SD cards in most of my Fires (even briefly in the 2019 one) - just been the "bog standard" ones purchased here on Amazon. I usually only use the 16 or 32Gb ones, larger ones seem to have more problems (or so it seems to me)
The Fire seems to be "seeing" the SD card - so that's a good thing in that there is probably not a problem with the slot itself (I hope.)
Would it be worth backing up any of your personal data on the Fire and then (a) checking for any software updates outstanding and/or (b) doing a simple Restore Factory Defaults (probably with the SD card out of the Fire)? It may be a minor software gremlin causing it to glitch.
I'd suggest using the HELP link to contact Amazon help desk for free to see if they can talk through the issue.
