I originally noticed my phone working slowly and messages particularly glitching when I downloaded iOS 8 my iPhone 5. Since my phone was almost 2 years old at the time and its storage was basically full I figured it was just from that. However I recently upgraded to a new iPhone 6 64gb and I'm having the same glitches. These glitches include messages not showing texts after saying I've received them until I've quit the app, opening messages and just having a white screen, messages showing notifications after I've opened the texts. I feel like the software on my phone is having issues is there anyway to fix it without restoring my phone and starting new
