I have an iPhone 6s that is mostly fine. Different iOS updates tweak how the screen looks much to my chagrin but most of the time I’ve been able to adjust. I also got on well with the iPad 8th gen. Both have really basic LCD displays without True Tone, wide color, variable refresh, etc. I will probably try to switch to one of the newer iPhone SE models if this 6s stops working.
