About a week ago, my iPhone 5S started acting very strange. Whenever I go into my "Messages" app, it either shows up as a blank white page or shows previous messages but the screen freezes on the page. Sometimes I am able to text but then it starts freezing again. I am unable to call anyone. My battery is drastically draining. My phone just decides to freeze randomly and will turn off by itself. When double clicking the home button to "close" apps, my phone freezes. I have tried to update to the new IOS 8.1.2, but whenever I choose the "agree" option, my phone doesn't do anything. Please help!
