you both made your point over and over, no one asks this.
I find it a bit condescending and misplaced that you believe to have the absolute truth that this is a use problem and not a device problem.
If first you would hold my phone, point yourself, see the number of pictures and clips with horrible results, EVEN WITH SILLY STREET LIGHTS OR OTHER MODERATE LIGHT SOURCES, then maybe you'd have the power to make these bold statements.
You made your point. It is clear more and more people find this forum topic because they clearly thought: Hey, this can't be normal anymore compared to my former iphone or other. So that alone confirms the problem.
The only thing i agree on: more than confirming you are not alone with the problem, this forum will not provide you solutions. I will also contact Apple and i advise you to do the same.
