I've had 3 generations of Samsungs and I really want to switch to something different, possibly the LG G3. What would really convince me is if I could reasonably anticipate a rock solid AOSP ROM for it at some point in the future. I'm sick of Samsungs bulky and laggy Touchwiz, and I've fallen in love with the pure Google experience that AOSP roms offer; but while they work OK on the Samsung, they suffer from a drop in quality and performance because I am told Samsung drivers are not open source and they have to use open source alternatives.
I've noticed that LG have an open source code distribution page with software for phones on it. Now I'm no developer, so the question I am asking is - do LG release their code open source? And does this mean that original developers are able to drive the LG hardware properly? What were AOSP roms like for the G2?
