Thanks for responding. I think you need to back up your claims that iOS lacks testing (really?) and has a poor user experience (a very subjective claim) a bit further. The only point I really agree with is the incoming call unavoidably taking up the whole screen.

With respect to the shutter sound, in the title you said, "no way to disable shutter sound", and then you contradicted that statement in the paragraph below with ways to do it. You also claimed that you have to completely mute the device or use a workaround, which is misleading at best. Shutter sound is togglable via the Ring/Silent Switch (which does not affect music playback), the alert volume and the system volume, so you have at least 3 options.

The inability to delete multiple contacts is also untrue, you can do this at iCloud.com. A simple web search will show you how to do this. If you don't have iCloud, some apps also do this.

The reason for my criticism is due to how you approached the topic, prepending it with "This is not an Android fanboy post where I criticize Apple recklessly." - when it comes across to me as doing exactly that.
