I just got the lollipop update (UK Vodafone version) and I'm having a few issues with touch wiz. Everything is laggy and slow. It removed some of my app icons from the home screen which happens sometimes however I can't put them back now - dragging the app icon from the apps page results in a "unfortunately touchwiz has stopped" message. I've tried restarting the phone and a soft reset but nothing works and it's doing my head in. Anyone had the same problem or got any solutions?
