I've recently tested the following phones:
TCL 50 5G - Horrid toxic backlight issue. Phone is unusable on low brightness, and high brightness feels very uncomfortable. Eye strain symptoms developed, and I was not able to concentrate when reading web text.
Honor 200 Lite - Beautiful aesthetically pleasing handset. Very thin and light, and performance was ok. I managed to use it for an hour before the dreaded amoled eye fatigue and strain developed. Felt fatigued and spaced out for the remainder of the day, until the next morning.
HMD pulse pro - Same toxic harsh backlight issue, causing eye strain. Mediocre system performance.
Honor Magic6 Pro - Beautiful looking device, but even with all the eye comfort tech and increased pwm rate, my eye's were fatigued after a half hour, and a tension headache developed.
Realme 12 pro+ - Headache/eye strain/fatigue within minutes. I felt that eye burning sensation.
It pains me to say this, but even the newly released LCD phones have practically become unusable. Each one I've tried (Moto G54, Nokia G42 5G, Redmi 12 5G, TCL Nxtpaper 40/40 5g, TCL 50 5G, Honor X7B/90 Smart etc etc etc) have horrid harsh backlighting, and it causes eye strain, and an inability to concentrate when reading text.
I traded my Honor 70 Lite in for another 70 Lite - and made sure not to update the software. Although the performance of the phone leaves a lot to be desired, it's the only new (2023) LCD phone that hasn't presented any eye strain issues.
The Realme 7 5g, Realme 8 5G and Realme 9 pro 5G, Nokia G60, Oneplus Nord CE 2 Lite 5G, Poco M3 Pro 5G, and the Honor 70 Lite (pre software update) are now the only phones that have comfortably worked for me over the last 2 to 4 years.
These LCD phones don't seem to have the nasty toxic harsh backlight issue that the new current phones have.
I'll be heading off to a ''no tech permitted'' retreat abroad for a few weeks. No phones, laptops, tablets or computers will be allowed.
I'm really looking forward to it. It'll be the reset that I think i need. 🙏
