Hi guys, Yesterday evening I updated my Galaxy S4 to Android 4.3. After, I was very happy because of the new lock screen. It had great features, like Facebook and Instagram on full page, news on all page, etc. I was very enthusiastic about it. But, next day in the morning it dissappeared and now I have the standard lock screen prior to update. ( I don't understand why?? I didn't do anything. Does anyone has the same problem? How can I go to the new lock screen? Please, please help me! This new feature is so great, I wanted back! Kind regards.
