“For better cameras” like… I don’t see it. Back in the mid 2010s and late 2010s before the bump trend iPhone, Google and Samsung had the best phone cameras, and both were flat and with decent digital zoom and stability (for a phone). If you look at the photo samples for back then and compare it with now the difference is almost imperceptible.
That ugly bump makes big phones even harder to use and weight more now, plus if you’re one of those who never liked using a cover now I bet you’re forced to use one because of the added vulnerability of the bump.
Edit mid 2010s to late 2010s (until the camera bump appears around 2018)
The bump is what it takes to deliver the product that most buyers want. between the stats we already want and advertising influencing what we want, the best seller ends up being the phone with the bump.
If you don’t like that, you’re looking for some kind of limited edition for a specific market or cheap version of the latest and greatest.
They do still make a few flip phones if you want to go hardcore with your approach.
