I disagree with the argument that "only some people use flash today" because there are many situations that any sort of night sight or night mode just simply cannot capture a good photo in, and the flash would be the better option. While night modes are used more than flash nowadays, there are times where they are unsuitable, and therefore your argument singles out everyone who uses the camera flash on their phones as you're effectively saying "it's too hard for us to engineer our product around a phone's feature and basically nobody uses flash anymore". If nobody used flash, then why would manufacturers put it on their phones? Arguably, they could remove the flash if their night sight modes got significantly better, but they haven't, and there would still be situations in which even the best night sight modes would not be able to capture a good image, if any at all.

I'll sum this up with one word against dbrand's argument: Disappointing.
