T-Mobile LG G3 D851 haywire after Marshmallow 6.0 update

[healthylaff]

All after Marshmallow Update:

1st - sketchy performance--drained battery causing boot loop

Then worked when plugged in AFTER a hard reset. Battery now fried (friend's battery worked fine).

Ordered new battery.

Next - got new battery & worked fine for a few days afterward

Intermittent freeze/audio glitches fixed by removing battery briefly, then worked perfectly for 12 hours

Awakened to audio cutting out, removed earbud jack and pushed back in helped

30 minutes later all mic/speaker/audio dead...not a single problem before installing Marshmallow Update from T-Mobile!

Welcome back! That sounds terrible. Does all of this still happen in Safe Mode? https://support.t-mobile.com/docs/DOC-11934. If so, I would contact T-Mobile and let them know what their update did to your phone. Ask them what they can do for you, since it was their update that caused all of the problems.

Root LG G3 and use greenify. Do factory reset before rooting your device.
