After using android since the iphone 4 i decided to buy one of these for a change and can't say i'm disappointed.
Having used an S8 for the last 15 months with the screen on full saturation mode i can honestly say i have no issues with the XR's screen at all. I really don't know what all the fuss is about and those at work with the iphone X can't tell the difference between the screens..
I'm not sure i would notice any diff in the performance of the phone if the ram and screen res were increased as it runs really smooth as it is, so i have problem with it having 'only' 3gb..
The £750 price tag is hard to swallow but i did get 10% off using my credit card voucher points so softened the blow a bit
