ISO sensitivity and dual ISO in smartphones: Are they important?

ISO 409,600 – that’s what Huawei used to advertise with fervour for the P30 Pro and P40 Pro. At the same time, some professional DSLRs, which are several times more expensive that the handsets, “only” achieve ISO 102,400. So do Huawei’s smartphones deliver four times the performance in night shots? And is ISO sensitivity that important for smartphones? Spoiler alert: No! There may be just one exception.
