Same thing with my phone. Battery level icon now white which has always been green since I bought my phone a year ago. Also, having issues getting my email and messaging since the update.
Running in the same issue, keep having to reboot to send SMS. Also finding that MMS I need to reboot to receive it's as if the data just stops. However SMS I am receiving just fine.
Mine was updated by Verizon this morning and now my battery does not charge properly! Batter seems to draining faster than normal and while plugged in it will still loose charge. I only seem to get it to charge by having to turn it off and it still is extreamly slow to charge while turned off. Do not like at all.
MK2 to NC5 this morning, immediately killed inbound email. Tried clearing system cache per first page of this thread, no change. Email app claims "Master sync has been turned off". There is no setting anywhere for turning it on or off. When I go into accounts/email, it takes me right back here. Tried toggling it on/off with no change.
I'm also having serious problems after "upgrade" Lost wifi connection - simply won't connect, tried factory reset, remove batt, wipe system cache, reset wifi settings but I see from others including folks from Sprint and ATT that this is a widespread mess. Come on, consumers are tired of being used for beta testing on untested crap.
Phone was working great until this "improvement"
Ok. I reinstalled my router and everything is better. Battery icon is still white, but seems to be going down as the battery goes down. Weird.
I must be one of the lucky ones. I have noticed NO problems since updating to Kit Kat with the exception of one app. The app backed up all my downloaded apps to the SD card, but after the Kit Kat update it lost the ability to recognize the SD card. I contacted the manufacturer and they are working on correcting that issue.
We want you to enjoy updates, since they're meant to enhance your phone's functions not cause problems, I apologize. What happens exactly with the data? Does it revert to 1X? Does it happen at a specific location?

I have two Galaxy S4 phones. After the update, my phones drain their batteries super fast and the charging process is painfully slow. I used to be able to charge the battery from 20% to 100% in just over an hour. Now it takes 3-4 hours to do the same charge. On top of that, the phone is heating up a lot. It's ridiculous. I've noticed no improvement in performance whatsoever after this update. So much for updating for the sake of improving the product. This update is going backwards in performance.
