Why are apps disappearing from my SD card?

[AC Question]

Hello all! I'm sure the title to my question has been asked before but upon checking different threads I still have not found the answer so allow me to go into detail.

I have a generic, off-brand phone that runs Android. It's manufactured in China.
I recently purchased a mini SD card, 16gb, class 6 to put in the phone because I was running out of memory.
After moving the apps to the SD card they at first function normally but when I rebooted my phone the apps disappeared. I tried to reinstall them again and move them to the SD card and this time I did not reboot so I thought all was well.
But when I woke up this morning and checked my phone I noticed that the apps are not starting when I click on it. The app icons on the home screen are still there but they just won't run. When I click on an app I get a message that says, "Unfortunately, (name of app) has stopped." and it flashes this message non-stop. I have to go to Settings, click on the app name, and click clear data to make it stop.

This is really frustrating and I have tried to do different fixes that I have encountered but none work.

Please help me with this. Unfortunately, due to circumstances I cannot easily upgrade my phone so I need to fix this issue to make it useful. Thank you all.

This may be probably due to trojan viruses you may install stubborn trojan killer from play store and run a scan this may scan and solve the problem try it

I too had the same problem, and I lost all of my data and apps that were on SD card, and it was not even recovered.Finally I had to buy a new SD card so as to resolve the problem.

Thank you for the reply. I just did and it found no issues on my phone. So I'm still looking for another fix.

I guess I will have to do that as well. It's a good thing I have a warranty on this SD card and can take it back for an exchange. Hopefully it will fix the issue.

Hi guys I have the same issue, suddely I loose the apps saved on the sd card! why? I click on the icon and it says "app not found" I had already installed them again but problem occurred again. What I have to do? change SD card? but I could back up the card without problems. It doesn't look like that it's the card.
Any suggestion?
Thanx
