I didn't say there was any OS changes, (though your comment isn't true) with android l. I simply said boost Mobile doesn't care about updates and LG has a terrible software update history. They've already confirmed the g2 and g3 are getting it. They haven't said anything about any other models. I'm not trying to rain on anyone parade, I figure you guys should be prepared not to get it and be happy if you do vs. Waiting for it and being let down if you don't
There ARE major OS changes. ART, which is optional on kit katt will be the standard for android l, battery improvements like project Volta, interlocking apps, heads up notifications and finally if you know anything about Samsung KNOX, do some research and you'll see that's gonna be included in android l as well.
