And there you go. Lol no clue on what I'm doing today. So back to the? I put the card in and it basically said it all... Internal or portable. Lol. Well that's easy always internal for me. Format it and I'm on my way. That card is a 2019 SanDisk Image mate class 10 A1 micro SD card; OH and that's it. But it works perfectly for me and video. .... So and here we go.... I went out and bought a new Image mate Pro 128 g. V30 A2 U3. and the list goes on and on ilabout how great this card should of been. Nope not even close to the other one that by today's standard is a million years old. Yeah this cardod only formats in portable and well.... Which for me is not even worthy anything to me. Don't get me wrong, I don't have anything against having a pile of photos. Lol but I don't. I love having space for apps and functional stuff and some pictures and stuff. Now that card went in a cheap TCL tab 8 tablet with, and there it is again only 3 gigs of RAM. But yes I don't know why this card will not work for internal app storage and other stuff. And it's supposed to be the better card . Anyway, anyone have a clue on that. Sorry about that long winded post to finally get to the? Question . I also got 3 NCY Elite 64 gig cards also that are doing the same thing . You know really nice cards but again I'm finding out other wise. I mean it is pretty straightforward to format, but if I don't have a choice to go with internal, I rather not bother. So I'm amazed at the oldest and cheapest card was and still is the best one. So any advice?. Thank you for your help and replies.
