I installed flash after I initially got the phone and not all videos worked in the desktop versions of Youtube, MSN, etc. Also, desktop versions of facebook games (non-app). Flash videos in the browser did not work on my Razr HD either without Flash being installed. I'm interested in how yours works since many desktop specific videos/games require flash to play them; although flash hasn't been available in mobile browsers for quite sometime without the .apk installed from an SD card.
I like Nova Launcher because I can stuff my apps and documents into folders which I keep in my drawer, and I like to be able to hide apps so I never have to look at them again (i.e., bloatware which you don't have the option to uninstall from your phone - non-rooted). Also it gives me many options to customize the look of my system by designing it however I want. The UCW builder is AWESOME. I love to build my own widgets, etc., with links to whatever app I want them to open on touch.
I am surprised I did not think of turning off the scanning thing. I thought I had it set to automatically bump over to mobile data (I am still holding on tight to a grandfathered unlim. data plan). Mobile data was on, however I had not selected the advanced option of "auto network switch" which will make a difference I think. For some reason "always allow scanning" was selected so I deselected that as well so hopefully that will help to save battery life. Thanks for those tips.
As an amendment to my previous post, the S-note widget crashes every day, actually. It sits at "Loading..." and never does anything. Which is kind of a bummer because that's one of the awesome stock software features of the Note 3. I figure that will have an update which will sort itself out eventually. Hopefully...
My Firefox crashes a lot now too, and I am hoping that a fix must be on the way from mozilla for that.
