This issue has me completely baffled and frustrated. I'm currently on my 3rd LG V10 after 2 AT&T warranty replacements. My first device just bricked one day and ever since I received the replacement device from AT&T, I have apps disappear from my phone when I reboot. After about a month of dealing with it on that 2nd device, I called AT&T and walked through a few tests with them and they agreed that my hardware was probably to blame and sent another replacement device.
I've had that one for about 2 weeks now. I rebooted the phone several times after I received it and had all of my standard apps installed and all seemed good. However, earlier today, after a couple days of above average battery drain, I thought I'd reboot the phone and my heart sank when my phone came back to a half populated home screen. A large number of apps are nowhere to be found on the phone, just like the problem I had with the last device that AT&T replaced. So, hardware has been ruled out and I've spent tonight testing various other changes on my phone to see if I can find a scenario where the apps survive a reboot. I've picked 4 apps that seem to always delete on reboot (now and with the previous device), Hangouts, Pocket Casts, Feedly and Google News & Weather. I use my phone for work so I've backed out of the Mobile Iron install and reinstalled these 4 apps but the apps still disappear. I've removed my microSD (as I'd read a number of app deletion issues around external storage on other devices) and again installed the apps but the problem remains.
I've played around with an app called List My Apps to capture the app list before and after a bunch of these tests and I've noticed that some of the deleted apps seem to actually re-appear on my phone after it's been booted up for a while too. Prior to my last reboot, the app list generated actually included several apps that had previously been missing without me manually reinstalling them from the Play Store. Authenticator, Google Cast, and TripIt were a few of them that showed up in the list before that reboot only to have again disappeared after the reboot. Unfortunately, I didn't see them back on the phone before rebooting to see if their settings and configurations were also intact.
I'm completely baffled by this issue and it clearly cripples my use of the phone. I have no clue if it's something about the apps I use, the settings on my phone or something else. My first LG v10 hardware (the one that bricked) never had any app loss issues with largely the same app set. My phones have all been encrypted, which is my next test once I can run the decryption process when I get my battery charged up to 80%. Because I use my phone for work, it's not rooted which seems to greatly limit my access to any log data from the phone.
Any suggestions or debug tips would be greatly appreciated!

There doesn't seem to be any rhyme or reason around when an app was installed although most apps I've installed in the last few days were removed...Pokemon Go included :rolleyes:
