LG G3 big B is not playing any Video

[Android Central Question]

7I have had my lg g3 for almost a year. I've never had any problems with it before but now it won't play any of the videos in my storage. I have everything saved to a memory card and the videos have been taken over the years with different phones. Today I took one of my daughter and went to show it to her dad and it popped up with a black screen with the play and rewind/fast forward buttons at the bottom and in the middle of the screen or says can't play video. Its like that for every video on my phone. I can still watch videos on youtube, netflix, facebook. Just not the ones saved to my phone. I can still view all of the pictures and screenshots and can even see the thumbprint image of the video. I've turned my phone off and back on, taken the memory card out and put it back in. If anyone knows how to fix it I'd greatly appreciate any help

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 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/am...guide-using-chkdsk-fix-corrupted-sd-card.html. If it finds bad sectors, and the photos aren't crucial to save, then go ahead and allow chkdsk to try repairing those sectors. If the photos are really precious, then you'll have to try recovering them using 3rd party software: http://forums.androidcentral.com/am...os/500142-guide-recovering-deleted-files.html

I strongly suggest taking advantage of the Google Photos Auto Backup feature, which can save you these kinds of headaches in the future: https://support.google.com/photos/answer/6193313?hl=en. Remember that SD cards don't last forever, and they are inherently less reliable than onboard memory, so the risk of data corruption is higher. Don't rely on an SD card as the sole storage location for important data.
