Camera refuses to take picture on 10 III (focus hangs)

Does anyone have a view on whether the Jolla C2 camera is likely to be better than that on the xperia 10 iii in terms of general quality?

The camera on the 10 iii wasn’t bad, infact it made some nice images, but the camera on nearly-10-years-old lumia 950 has it whipped in a lot of situations: even when I was using Open Camera.
