    I just got a 512 evo samsung micro sd card in the mail. I got ready to format it and the phone said it was corrupted. It would only format to 20% then freeze. After a bit the phone would restart, but freeze on restart. I had to reboot. I formatted it with a PC in 2 seconds and it works with the phone now. Should I keep it or mail it back?
    Using a samsung a50.

    Check if your particular phone actually supports SDXC type micro-SD cards?

    Also check if it's a fake as well. Did you buy it from a reputable retailer? As there's a lot of counterfeit micro-SDs around.

    I used to recommend a great app called SD Insight that tested for legit cards, but it has not been updated since March 2018 and is effectively abandonware. However: there is another app, Fake Device Test that will check to make sure your 512GB card is really a 512GB card (or whether it's a 16GB card marked & formatted to appear to be 512GB). If you value your data, I highly recommend it for any, and every, new memory card you ever get for your phone.

    Just remembered, when I started the scan, i got bumped and dropped the phone (about 18 inches dropped onto padded carpet.) When it picked it up it showed 20% and never changed

    If you mean the data size of card, then yes it does. It supports up to 512gb card

    Dropping the phone while doing that formatting process is most likely a significant point. You mentioned reformatting the card successfully in a PC but did you actually try to do the same in your phone again? The card might be fine, dropping a phone when it's doing anything will typically not work out too well.

    Svim: just tried to format on the phone. Screen went immediately to 20%. Had to reboot. Then the card said corrupted. Also via a PC I had put 50 gb of music on it and the phone said there was only 27 gb. I saw this before I tried to format with phone

    Return this card and get a new one. It's apparently damaged -- since the formatting on your PC does actually indicate there's a serious problem, if you're still covered under a replacement warranty you should take advantage of that.

    I returned it and got one from another dealer. Same results, returned it. Ordered a san disk from a dealer I had luck with and it worked fine. On the second, I did do some checking and it was a fake

    So many times it's been mentioned in here why would you buy an external sd online when you can just drive to the store and get one..so you can avoid so many head aches..

    I would never buy one online..I guess is just me.
