I remember the old Nokias that made 320×240 pixel photos. Phones since are made thinner, which would afaik result in more problematic focus points for lenses. Yet quality has improved significantly.
How is this possible? And is there a technical limit of how detailed digital photos can get? As opposed to traditional lenses, where the size of the lens can be as big as you want to make it.
Tagged as technology, but I guess this question borders physics.

Much of the improvement comes from improving the actual image-capture side of things, not the lenses. In fact, many phone cameras today have inferior lenses compared to what they had a decade ago, specifically because those things have been sacrificed to make thinner phones. Have you noticed, for example, that many phones stop “optical” zoom pretty early, but still allow you to zoom in further? That’s because you aren’t doing actual zooming anymore, you’re just *cutting down the image.*
