I was updating the 'Samsung Apps' app yesterday when it froze the phone so I went to restart but when it came back on 80% of my apps were gone and Google play store was nowhere to be seen. I went and upgraded my phone to ISC as I had Gingerbread still but this still has not helped. When I go in to Application settings it shows all the apps I had but whenever I try to open it just says 'Application is not installed on your phone' and I can't re-download as I cant find the Google play store. And my SD card still works as all my images and movies and music are loading on the phone just not the apps. Anyone able to help?
