Everyone has there own opinions and I didn't think mine would be popular.I don't see the point in Samsung adopting the boxy shape for the entire lineup... for what purpose? To stand out.
The reason why Ultra series has a boxy design is to incorporate the S-Pen, if it wasn't for the S-Pen... I don't believe Samsung would have made it that way.
If there is one thing that Samsung need to really improve in regard to hardware... face unlock. I'm part of the foldable group and I know in-display fingerprint technology is the focal point for their slab phones.
But I'll like Samsung to put more resources behind face unlock technology. And I know that UDC is around the corner too (RedMagic 9 Pro has done it successfully).
I like the boxy design because it is a Samsung original and not a copy of Apple rounded corners. Yes, it is simply to be different. I want an Android phone to look different than an iPhone. If I want an iPhone I will buy one. I don't want a Android hardware copy.
One of the things I like about Pixel is that the design is completely unique even if they do use rounded corners. The s23 series other than the ultra doesn't know if it is trying to be unique or a copy. Samsung has the talent and money to create a unique and compelling design language within the confines of the bar phone format. I think the s23 ultra is unique and a stand out and I just want more of that.
All that being said I am not complaining about the current line design or next one, maybe the colors but the design is good. But you can make subtle design differences that make your product stand out. Nothing has done it, Google has done it, Apple has done it but Samsung is just kind of a generic amalgam and it could be more.
