    3rd worst mistake of my life... (don't ask)

    LG G3 D851 was working just fine until I "upgraded" to 6.0 Marshmallow.

    After Android 6.0 update OTA via T-Mobile, phone calls were terminating quickly and then got to the point where they didn't work at all. I used Google Voice almost exclusively, but problems were occurring for T-Mobile direct calls, too.

    The phone call issue seemed to grow, and the update then ruined my battery from boot looping.

    At my wits end, I did a hard reset (btw, is there any way to save app preferences and restore them) and it seemed to work ok on AC power ONLY. If I unplugged it, it went right back into boot loop, even though my battery was showing 100%. I know it was my battery, because I tried a friend's battery and it worked ok.

    So I slowly installed more apps, and finally got a new battery, so I could use it without being plugged into AC. Things seemed ok for a couple days, then today the same phone call problems and freezing were back again!

    Occurred after updating eBay app, but have no idea if that was the culprit, because I have all apps set to update automatically on WiFi (probably not a smart idea).

    Did the Google Voice trick (remove app from phone, then go to PC and remove real number from GV list on PC, then go back to phone, reinstall GV app and have GV find my real T-Mobile number automatically and add the number from the handset), but 'unable to complete phone call problem' is back on GV or the T-Mobile network.

    Super frustrated and angry. Nice effing "update!"

    Any known app conflicts on D851 running Marshmallow?? Ideas?

    I'm thinking another hard reset, but would love to save all my app preferences to restore them (doesn't seem to work on LG PC Suite, which is what I used for backup last time).

    TIA.

    Do you have wifi calling set up and do you use it on your regular calls (not GV)

    I ask because Marshmallow affects wifi in all phones and it's a big issue. I can't be sure that it is the main issue on your phone but it is something that may be happening.
