I have LG G3 for almost a year now and it worked without problems and I was really happy about it. But about a 2months ago it started freezing and restarting. Maybe it was because of a high temperature or I don't know. But yesterday it started closing my apps. Just the downloaded ones like twitter, facebook, games. Every one except snapchat. Every time I click on them they open they work normally, everything loads and then they just close like nothing happened. It doesn't even give me the window that the app crashed, it just returns to the menu. I tried restarting, taking sd card off and clear cache.. I am really desperate. Thank you
