My Samsung S3 is 2 months old and I have had this happen 3 times so far. This evening I couldn't pick up any incoming calls because the screen was frozen and no matter how many times I swiped, it wouldn't respond. I am also getting black screens and excessively long refresh times after I send a text for example. I talked to my supplier and he just shrugged and said check the forums so here I am. Any ideas? I did install a task killer and dropbox which I am in the process of uninstalling. Any suggestions? short of a factory reset?
