Hello, I have updated (clean install) to iOS 8 and after few day of usage went back to iOS 7.1.2. I didn't like iOS 8 much, 1. It drains battery faster (no third party apps installed) 2. Safari is slow 3. Device is usually hot (no third party apps installed) 4. Poor - Call quality Am I only one with these problems or i am not able to live with these problems.
