Having upgraded to the new Iphone SE from the old one, I am frequently hearing certain strange sounds, mostly when I wake or unlock, but sometimes otherwise as well. If I have to describe them, I would say like a swoosh sound sometimes, or a very short noise of people as in sports, or even some animal-like sound. Anyone experienced this and know what they're about. Of course no hindrance to my use of the phone at all, not even a bother as they are momentary, but just curious to know what they are about.
Thanks in anticipation!
