Why does ios 7 look like its unfinished?

In my way of view it looks like its a unfinished beta version and they released it to the public just like that! It's plain and boring. With hackers being able to hack into other people's iPhones and all that it seems like they don't even get people to test anything out!

Its plain and boring because they are following the new "flat trend" in web design. Look it up. Extremely ugly though.

It's flat, not plain… Flat is the current design trend for user interfaces, especially on mobile. The lockscreen bugs for iOS devices has always been present as well, and it's nothing new.

"Flat" is the new trend for user interfaces (eg. Windows 8)
