IOS 8 updated on my iPhone and icons in games are so small.

I updated my iPhone to IOS8 and now the icons are really small.

Greetings arthurfrombaltimore,
Welcome to the Apple Support Communities!
I understand that your iPhone and iPad are both restarting sporadically and displaying the Apple logo. In this situation, I would recommend reading over the attached article and using the information within to continue the troubleshooting process. 
If your iOS device restarts, displays the Apple logo, or powers off while you're using it - Apple Support
Best,
Joe
