Hi all, I am using a Huawei Nova 8i which does not have a LED backlit panel, however, the device does give me eyestrain with prolonged use.
I have noticed though, that when I use this phone in the car, or in my lounge which is brightly lit with sunlight from my windows my symptoms don't appear for a much longer time than if I was in a darker room with artificial light.
Just thought I would let you all know.
