If the quest is to alleviate eye-strain from multi-strobe PWM dimming (a.k.a PWM for short), then the Xperia 10 II is a even worse offender than most other smartphones. Why?
Notebookcheck seems to have measured a ~116hz PWM dimming frequency for it, which is painfully low.
One has to look for either 0hz (meaning it uses DC dimming in all of it's brightness range) or >10kHz PWM dimming to be sure that it's not the culprit to eyestrain. Ofc, some people can tolerate ~2kHz PWM dimming too, everyone is different!
This article should be a good introduction to what PWM dimming is and all of it's forms.
Now, there's a other kind of PWM, the good kind, It's called single-strobe PWM, or strobing for short.
There are some people that do not suffer from eyestrain caused by it and when paired with an OLED should lead to superior motion clarity (another big culprit to eyestrain too!)
One way (in Laymann's terms) to achieve strobing on a display is to make the refresh rate match the PWM dimming frequency. So, for example, the S22U has a measured ~120hz PWM dimming frequency. If one could make an app that forces the phone to be in 120hz mode all the time without dropping it's refresh rate, regardless of what you're doing on it, you should essentially have a strobed smartphone display! Which COULD make OLED usable for some.
However, there are people who cannot deal with both types of strobing, so it is definitely not a solution for everything.
The Xperia 5 II, 5 III and 1 III are interesting however, as they seem to offer a BFI mode built-in, it does seem to have some quirks though.
But, to be VERY safe, as iterated many times in this thread, one should opt for a LCD display when wanting to avoid all of these eyestrain concerns.
I'm just very baffled how there's a lack of compact LCD android smartphones though, something akin to the XZ2 Compact. Phones are so massive nowadays.
