I use the iPhone 5s with iOS 7.1.2.
When I unlock the phone with my finger print, there is an animation where the icons move from the edges towards the center of the screen. After this animation is done, I have to wait approximately an entire second before I can swipe left/right on the touch screen in order to get to the apps on the other screens.
This is extremely annoying! Simple and quick tasks such as checking on emails will take far longer because I have to wait. This is very annoying and there is simply no way to avoid this and I don't know why Apple didn't fix this already. That's the first thing I ever noticed after buying this phone.
Will this be fixed? Is there any reasonable workaround (I don't want to install jailbreaks) ? I know that the out-of-the-box iPhone 5s doesn't do this that way. After you install the latest iOS, the error occurs (maybe it's a "feature"?)
This isn't a bug that's only on my phone. I did reset it once (out of other reasons) and the bug was still there. Later on my phone got stolen, so I bought a new one and it was still there.
According to ActMonitor, I have 230 MB RAM free plus 100 MB RAM inactive. There is also 3.6 GB storage available (out of 16 GB)
Take a look at 7:31 in this video. There you can also see it, but not as extreme as with my phone.
