My Take on the LG G2

Not an issue for me using Rocket Player music app. Sound is full and rich.

Tried the app you mentioned and it did nothing to help. Apparently the premium version has options to avoid clipping which is suppossed to stop distortion, but that still wouldn't help me if I wanted to stream music. So far Spotify has sounded the best but that's not saying a whole lot. I'm going to try plugging in through the aux port and see what happens tomorrow.

Phone was well behaved today even through a few hot heavy uses. Only threw one little fit which it got over quickly. It seems to act up when scrolling is involved (candy crush, lists, facebook) so I wonder if it tries to predict all outcomes of a movement and some algorithm just gets it wrong and has to be reset with a turn-off/turn-on.

Battery has been awesome. took it off the charger at 7:00AM yesterday (Friday) and just put it on the charger at 11:00PM Saturday with 5% remaining. Can't really scoff at that at all!
 
If you have root access I would enable aptX. The G2 has it built-in but it's disable by default on some variants like it was on my D801.

to see if it's enabled this in a terminal emulator or using adb shell on your computer:
Code:
getprop persist.service.btui.use_aptx

If you see a 0 it's off. If it's a 1 it's already enabled. To enable it type:
Code:
su
setprop persist.service.btui.use_aptx 1

This assumes of course that your BT devices support this.
