According to Counterpoint, the overall penetration for smartphones with glass backs will reach 26 percent of total smartphone shipments by the end of 2018. By 2020, Counterpoint posits that number will be 60 percent. Glass is cheaper than metal, and that combined with wireless charging capabilities makes it likely glass will be the first choice of OEMs going forward. As of today, many of the most prominent flagship smartphones feature a glass back design, including the Google Pixel 3, the Samsung Galaxy Note 9, the OnePlus 6, the Huawei P20 Pro, and the Apple iPhone XS.
