Same boat. Had a V30 but switched to a Pixel. Original dongle was shit for audio quality and malfunctioned out of the box. Ended up buying this and music quality has been great ever since minus charging my phone when I also want to listen to music...

Now that they have the gcam for the lgv30 I'd have probably just stayed with it and used the Nova launcher if I'd known how annoying not having an audiojack would be though.

Not a solution but rather a workaround...this converter has been suggested before and I bought one and it works great. I had issues with the Google dongle too and haven't had any with this one.

eventually bought that and I did get it in, but as I've been using my bluetooth headphones recently that I really like, I haven't even tried it to see if it works. If I remember I'll test it out in a few hours when I get home.

I picked up this one, it has better shielding than what came with the 6T so less electronic noise.
