    I have an Optimus LG F6 (version 4.1.2). When i tap on an app its a black screen for a few seconds and then it goes back to the home screen. Ive tried restarting my phone multiple times, reinstalling the apps repeatedly, and factory reset my phone twice, but still have this problem. Please help.

    Welcome to Android Central! Does this include system apps as well? Try booting into Safe Mode, which temporarily disables all 3rd party apps. On most Android devices, while powered on, press and hold Power until the Power Off menu appears. Press and hold the Power Off selection until the Safe Mode prompt appears. Tap OK.

    If the problem disappears in Safe Mode, then something you installed is causing the problem. You may have to uninstall apps one by one until the problem disappears. If the problem persists in Safe Mode, then it's more likely to be a hardware or firmware problem.

    The problem is still there, so what would have to be done?

    It might be a firmware or hardware glitch. You could try installing LG PC Suite and see if it lets you reinstall the firmware, but I'm not sure if it's compatible with your model: LG PC Suite: Manage Your Photos, Videos and Music | LG Hong Kong. Otherwise, you'd have to root the phone and reinstall the stock ROM that way (search a place like xda-developers.com to see if that's possible). If it's a hardware issue, you'd have to bring it to a repair shop, or contact LG if it's still under warranty.

    Actually i just tried it again (an hour or so later) and my apps work, except one of my apps (ifunny) has disappeared. And if the systen apps are apps like google chrome, youtube, calender, maps, text messages, etc, then yes those open and work normally

    Were any of these apps that weren't working moved to the SD card?

    The card might be failing or corrupt. I would move all apps back to the phone, then try a different card.

    I'm sorry, I'm a little confused--I thought you said it seemed to fix itself, except for one app. Are all apps not opening again?

    Then try reinstalling the firmware as I had previously suggested, using LG PC Suite.
