Some of the bugs are about to vanish, as Apple has just launched iOS 7.0.5 update for the iPhone 5s and iPhone 5c which makes some minor bugs go away and fixes network provisioning for Chinese models.
The new update is rolling out in China, Croatia, Germany and the UK with the rest of the world seemingly missing on it. It seems the update targets specific model iPhones and won't be available for all iDevices. But don't worry cause Apple is working on iOS 7.1 update which will bring changes to keyboard, contacts app, changes to the phone UI. iOS 7.1 update is expected to hit all compatible iGadgets worldwide very soon.
