Well, I just want to get to the point. As mentioned in the title, the phone is running really smooth and I love everything g about the device. However, I notice that when I update as throw the app store, the device tend to lag and overheat a little bit. Don't know if anyone else have the same issue but actually it easy worth mentioning that here. When I turn the device off after updating the appreciate and keep it off for about 2 to 5 minute and trun it back one. Everything start to work just fine. If anyone have some issue with app overheating the device or something, please post a comment below.
