Finally found a suitable Phone! T Phone 3
My brother got a phone from his provider...it's called Telekom T Phone 3. I don't know if it's available outside Germany, he got it for 3€, you can find it new in stores under 150€, but there are plenty of sealed phones on the market for like 50€ because so many people got it from T-Mobile for 3€ just to sell it right away.
It's not a flagship of course, but i'm really impressed, the system is pure android, no bloatware, very snappy for a Snapdragon 6 gen 3. You get updates till Android 18/ 5 years security. Screen is very well calibrated for eye comfort, with smooth whites/contrast, non glaring, sharp letters. Best I've seen on an LCD. Color accuracy is ok, speakers are meh. Downside is it's not very angle stable...if you look from the side the display gets a little darker...but who uses his phones from an angle really?
White background while weeping the phone looks a little weird/cheap because of that, first I was put off...but after like 15 Minutes use it was no problem anymore. If someone uses his phone mostly while jogging it could be annoying for sure lol. In dark mode it's extremely nice to use, easy to read, letters are sharp like on an OLED, but much less glaring and irritating.
On other LCDs I always had the issues that letters in dark mode were glaring, not sharp with light bleeding ...just tiring to focus on. This phone's screen is the opposite, but as i said it comes with light angle issues. I couldnt identify PWM with my camera...but its hard to tell if they don't use some very high frequency PWM, as I found no informations online and have no tools to measure it. And it's also hard to say how many panel suppliers they use...if the screens on all phones are similar. But man it's a huge relief for my eyes. And for that price I think it's also a no brainer as a second driver...for reading/surfing online, evening use etc.
