That wasn’t his point. His point was that even CURRENT phones have issues with exposure to the cold, so certainly a phone with a much softer plastic screen would be even more susceptible to this issue in the real world.I don't think many cyclists would fit a £1600 /$2000phone on their handlebars
I use a phone in a special pouch at my handlebars for Strava and Mapmyride. However it need to be a 5 inch device. My Huawei P20 Pro won't fit. My Lenovo P2 just fits when taken out of its case. I keep my active phone in the beast pocket of my cycling jacket.
