The 6.0.1 Marshmallow update was forced to my phone, and now my phone doesn't recognize any of the apps that were on my SD card. At first the icons were all grayed out, and when I tapped any of them, it said the app wasn't installed. This has happened before after updates and always cleared up on its own, so I waited a bit, but the problem continued. I restarted -- same problem. I wiped the partition cache -- same problem. The forum advised unmounting and remounting the SD card. I did that, and now the grayed-out icons don't even appear anymore. The phone can read the photos I've saved on the SD card, but it doesn't recognize the apps at all. The files for the apps are still there -- I can see them when I connect the phone to my computer. How can I restore the apps without having to re-download all of them (losing all my information and game progress in the process)?
