The manufacturer ID should be 1b, followed by an application/OEM ID of 534d.

Card CID – check it and compare to working ones.

Mine are made in the Philippines but this is probably not the only place so don’t get hung up on this. Text on the back is printed so it is read with the card contacts end pointing upward.

Correct font, especially for the capacity digits, some fakes don’t use the correct slim font. Slight bevel on the contact side, to help insertion. Smooth back, not lumpy showing circuit parts beneath the surface.

The card – lots of subtle details to check.

All of mine have, but oddly enough when I tried to check one on the Samsung China website I didn’t get anywhere with the verification code, the site was in Chinese though so I might have been doing something wrong. The real ones have them (recent ones at least), fakes might but probably don’t.

Hologram, with scratch-to-reveal verification code.

Look up the UPC from the barcode on the back and make sure that matches the product and size of your card. The correct size should also be printed on the packet. I had one fake that incorrectly stated a 32gb card was SDXC on the pack instead of SDHC, the card itself had SDHC printed on it.

Packaging info – the product information should be correct and match the card.

The gloss overlay over the printed areas should align with the printing below them, if it’s offset that’s a bad sign. Packaging quality – the image should be well printed, in high resolution and good bit depth on the colours (some fakes looks like they’ve been converted down to 256 colours).

These are very common and if you google for fake Samsung cards you’ll find lots of info on how to spot them. would give different results – as long as it’s a proper SD controller (not a USB mass storage adapter) then sending the command should work just fine. I can see no reason why different phones etc.

Others have suggested different hardware / firmware revisions might be an issue – quite possible but I have no way of knowing (all my Evo Plus cards work, so I can’t can’t compare against ones that don’t). First off, I suspect some people who are struggling have fake cards – there are a lot out there and some of them look pretty convincing.

I thought it was worth posting an update with some extra information. My recent post on how to change the CID on a Samsung Evo Plus SD card has generated some interest, but also a number of people who are having problems with it.
