    I bought a new SD card and it has given me nothing but issues.

    My original issue is that I copied all files from my old SD card to PC, then copied them to the new SD card and over half the files didnt copy.

    My next issue is that any app that is saved on my SD card wont open, it gives an error like it would if an app closed prematurely.

    It is no longer recommended to put apps on an SD card, they are not fast enough to be reliable. Remove all apps from the card and put them on the phones internal memory, then format the card on a PC and copy your files to it, check that the files are still on the card and mount it in the phone as external.

    Welcome to Android Central! The SD card could be corrupt, defective, or counterfeit. Install SD Insight to see if the card is genuine or counterfeit. Counterfeit cards are programmed to report more storage than they actually have, and if you try saving more than the card can actually hold, then files can start getting corrupt. (Be aware that SD Insight might not work on all Nougat and above devices.)

    If it's a valid card, then go to Settings>Storage, Unmount the card, remove it, and insert it into your computer. Can the computer read these files? Backup as much as you can right now, then run chkdsk to look for bad sectors: http://forums.androidcentral.com/amb...d-sd-card.html
