Any idea what caused it? They typically don't just go missing. Gallery is one thing but missing from QuickPic makes it much worse. Try clearing the Gallery cache.Also use a file manager to browse to the DCIM folder to see if anything is there.
Wow that sucks! But like lee said they normally don't just up and disappear. Retrace your steps to everything you did even to the night before. I'd say more likely than not you either moved them or put them on some "hidden" setting and didn't accidentally delete them. Or Verizon and/or Google+ for whatever reason transfered them to their cloud.
Did you try using your PC instead of a file explorer on your phone? Might be a little easier to navigate and should show any hidden files...
Don't lose hope yet! It seems unlikely you'd just delete the whole folder without realizing it.
well I happened to keep copies on PC so I'll search my picture folder for them and put them back on phone (lots of work ahead)
I did that as a "just in case" lucky me
BUT I would like to know how this happened and hope it doesn't happen again ...strange that it came off both quickpic and gallery apps
