I downloaded iOS 8 the first day it came out and let me tell you, it's not the best.
First of all, to download there needs to be at least 5 gb of space open. Like hello, do you want me to erase my life?
To get that space delete those selfie fails and apps you haven't used in so long.
You can't type fast! I normally type really, really fast. But now, if you type that fast your device freezes.
Lastly, it takes FOREVER to download and downloads 2 apps, Podcasts and iBooks. I don't know how to get rid of it!
Over all, it's okay but iOS 7 was much better, I wish I could uninstall. It's so hard to look through camera now!
