After the 4.3 update to my S3, I am having major issues with my wifi. All apps that require internet connection and even Google Play is having issues loading. However, when I switch to Mobile Network 4G the same Apps load up with no delay or problems. I have knowledge of the current wifi issues with the 4.3 update. Is there anyone out there with success in finding a temporary fix that works. I've tried hard resetting, safe mode - removing SIM Card and battery, and re-configuring the wifi settings. Non of those fixes worked.
