I have just discovered how bad the photos taken by the current stock app actually are. But a lot more has happened since I got my 8 in December '17. I have recorded a lot of video with stunning OZO sound. From owls and wildfowl in my local bird reserve, a pheasant in the woods - both completely without a single "click", and silence that actually is SILENT. The sound is totally spatial - you can here precisely where every bird is in headphones.
At the other extreme, I filmed a Polish samba band playing at last year's Bremen carnival at sound levels of at least 120 decibels with no noticeable distortion. Standing next to a Brazilian Repique drum, 12 inches in diameter, struck with a long plastic stick on its very tight plastic head, will deafen you, but my Nokia 8 recorded it without distortion.
No more, OZO produces all sorts of background noise at low sound levels, birds sound like plastic bags in the wind. Drums distort. My phone hasn't changed, but the software has. Or perhaps I'm wrong?
