Have been using headphones with my LG G2 reliably until problems started appearing sometime last month.
I've replaced the headphones with ones that are designed for wear during sports -- so the jack connection has some extra "give" in it -- but that didn't seem to help.
When listening to apps, the headphone jack indicator seems to go off and back on at random times -- which, depending on the app, either pauses the audio stream (so I have to pull the phone out of my pocket and restart it) or causes it to pause briefly and restart.
I've seen discussions elsewhere that talk about a hardware problem with the headphone jack, but before calling for support, I thought I'd check here to see if anyone has guidance.
I'm so sorry you're having this issue with your headsets nes49! I'd like to look further into this. Please accept my Follow and reply to my Direct Message.
