Just wanted to start a thread like this. I just compared my 12 mini display to my iPhone 11 display and had the same thoughts.
I much prefer LCD iPhones to OLED iPhones. And there is a reason I write IPHONES. Because to me, and I owned or had a lot of iPhones in my hands, LCD iPhone displays are so much better than the competition. I still own a 11 and the display, besides it couldn't be of higher resolution, is perfect. It is bright, often to me much brighter with certain colors than OLED iPhones. It screams quality and I wish they would have made an LCD iPhone with higher resolution.
To me starting with the XS, OLED displays on iPhones have gotten worth and worth. And I have seen maybe 20-30 OLED iPhones the last years, owning several as I switch from time to time. The X back then imo had better OLED displays with no washed out colors, only a small yellow tint. And since the XS it has gotten bad imo. I love my 12 Mini but I wish it would have LCD with the same resolution. The colors look washed out, esp text, like with every other iPhone I had my hands on the last years. It is not only the yellow tint, it is the text itself, the smaller the text the less readable it is imo compared to LCD. I have only had the iPhone 11 with LCD display in recent years and maybe I was lucky that it has a very high quality display but it looks much brighter in most situations than my 12 Mini. It should be the opposite. And this is not only my 12 Mini. It has been with several iPhone 11 Pro (Max) I wanted to switch to and tested and sent back because of these bad OLED displays.
I don't know why so many hate LCD displays and love OLED so much. The only advantage in my experience with OLEDiPhones is the black pixels, that turn off. Besides that there is no advantage.
But what I have to say too is when I look at Samsung smartphones, those OLED displays in flagship models always seem less washed out. Colors are brighter, maybe less realistic, but at least I can read without a problem. If that is Apple's way of calibrating to give us realistic but washed out colors, esp text, it is just wrong.
TO ME (!) Samsung flagship phone OLED displays seem of MUCH higher quality than iPhone OLED displays. Sorry, but when I read that iPhone displays were chosen of best quality etc. I don't get it. I can't read small text easily because of washed out colors, and that was as I said with every of these 20-30 iPhones, but it wins because it is more realistic? WTF. Samsung colors may be a little oversaturated but at least they are bright and easy to read and give the impression of high quality.
Sometimes I wish there would be a non Apple, non Android flagship device to buy. But no, if you don't want Android you need to go with Apple.
