Here's what I did so far:
- Unit is very nicely designed. Good feel to it. Similar to an XBOX type controller, but not as bulky. All the buttons and joypads feel great. Doesn't feel cheap at all. Does not feel like they will break easy either.
#1 I figured out. Settings -> Sounds and Vibration ->Volume -> Three Dots -> Media volume limiter -> Turn On -> Turn limiter all the way up
#2 still no clue.
Mine lagged once or twice since owning it, but it's usually due to something.. maybe a program hanged and then I had to close it or something. Wasn't just laggy for no reason.
I had the Incipio DualPro on my old phone and I got it again on my new phone. Great case. I've dropped my old phone before and no issues at all.
I rooted with Dirty Santa. While it was easy to do, I misread or missed a step, no problems though.
I like being able to get rid of all the LG and Sprint apps, drives me crazy that they sit there even though I have 96GB space on my phone.
