After not updating to 4.4 for quite some time I decided to update. (not yet to 4.4.4). Since updating my screen will refresh 3,4,5 times when opening an app. Doesn't matter what app, aquamail, cnn, twitter, bgr, feedly etc. I tried isolating to see if it only happens on wifi or 4g but it occurs without rhyme or reason. I have cleared the cache partition 3 times. I do not want to do an fdr since I have the phone and app setting set very well and don't want to redo everything. Any ideas or suggestions?
