It's not just premium design that phone companies are after with their glass-y casings, though. Wireless charging would heat metal bodies to ungodly heights, so, last year, Apple also moved to glass iPhones, just when it introduced wireless charging to the lineup.
Glass looks premium and lets you top up your phone sans cables but it has just as many negatives - it is prone to cracking very easily when dropped, and is a fingerprint magnet. Thus, replacing a shattered rear now costs a pretty penny and is, in the case of iPhones, more expensive to repair than the screen itself.
Looking around, there are only a couple of metal midrangers left and just one phone with flagship specs like Snapdragon 845 that comes with unassuming but durable plastic body - Xiaomi's Pocophone F1. This is why we wanted to ask if, a couple of years after their demise, you would buy a plastic flagship phone again.
