I have some widgets too--Resizeable Cal Widget and HD widgets for other things like Weather. All of the latter (hd widgets) were fine, but the Cal widget completely disappeared, including from the app drawer. I had to reinstall the Cal widget.. Once reinstalled--not just replaced from the app drawer but completely reinstalled from Play Store---it came right back with all old settings restored, too.
@dwneylonsr have you tried to restart your phone? I have heard that fixed the issue for some people on this thread.
I just installed the update..Kind of funky how the screen doesn't move up to reveal the camera below (like the iPhone does) I would never know until the phone unlocks that I opened the camera app. Just a weird bug.
As far as the colors go, I love them. I prefer dark backgrounds (favorite color is black) so the white doesn't bother me but I can see how it could bother some people but no one likes change apparently. iPhone gets iOS7 with all of those color changes and I've read people's anger on those colors (I don't like them b/c they are too neon for me) then they come out with 7.1 with darker colors and that helped a bit...
Maybe in the future Google will come out with darker colors...more grey-ish white and darker greys and such. Just a thought. Nothing we can control though so no need to get mad about it...especially when it was reported before they even released the update to the google version of the S4 or released the Nexus 5. Those angry people could have avoided it but they don't want to hear that.
I charged up my battery during the update (it needed to be charged anyway) and just finished installing and charging 16 minutes ago and it's gone down 3%...the only thing causing it is the screen cause it has been on for 10 of those 16 minutes. I don't see a bad battery drain but I'll have to wait.
I'm glad this update came out because it does seem like my service is better. I actually just got my S4 replaced because of the data service. I would have no service whatsoever (couldn't even make calls) and my mom's S3 would have 4GLTE and they would be sitting right next to each other. I hope this fixes the issue. I'm tired of these issues I've been having and if it doesn't get fixed I'm leaving Android for iOS because I just want a phone that works like it is supposed to and Android isn't reliable...I don't even see the Nexus 5 being reliable like that. Idk what it is about Android but it just doesn't seem as reliable as iOS/Apple. Maybe it's cause apple has stores and whatnot? Again, not sure.
Anyway, back to the update, didn't have to do a restart on my phone as all of my apps are working fine and everything. Can't test the GPS yet because I don't have any use for it plus it is very cloudy where I am at. Overall, glad I finally got it.
P.S. I've been dying for this update just so I can say I have KitKat. My favorite version of Android because it is my favorite candy as well. Stupid I know but, hey, it's a free update, who cares?! Lol
