I made a comparative analysis of camera startup between Android and b2g, both running KK. The splash screen animation is longer on Gaia that it is on Android making the applications slower to launch. Can we make it shorter? This is a video that illustrates the issue: https://www.youtube.com/watch?v=AR6iJYpPXIE&list=UUCZqppXIFKoOlpe4SiZ_Ksg&vq=hd720
Mass update: Resolve wontfix all issues with legacy homescreens. As of 2.6 we have a new homescreen and having these issues open is confusing. All issues will block bug 1231115 so we can use that to re-visit any of these if needed.
