Samsung Galaxy Alpha

Hello to everyone, I have a problem that bothers me. Since 2 days ago my phone went running very odd. The touchscreen won't respond in some cases. I made the test to my phone, the screen works fine, I made a factory reset but same problem. To explain what it's happening to it, for example when I go to contacts, messages or galery, the touchscreen isn't working, or in some cases with a lot of delay, but, on facebook or games, other apps it goes smooth with no problem. I'm so angry on it cuz I don't know what else to do. Please respond cuz I need all your help. Thank you

EDIT: I found the main problem. When I activate the "Visualize trough gestures", all the apps that have this feature, the touch screen won't work. Is there anything that I can do?
