Hi, I have a LG G5 and I have to have a headphone jack extension constantly plugged into my phone ( It's part of my Lifeproof case). How can I toggle the phone sound output between headphones and regular phone speakers while keeping the headphone jack plugged in? Is there an App that can do this that I don't know of? For those wondering, my headphones won't fit into the opening with the case that's on the phone (which has to stay) so i have to keep the 2 inch extender left in place at all times. A photo of an example will be attached.
