XDA-Developers has obtained specs and photos of the upcoming Motorola Moto Z3 Play, the latest of which showcase a very interesting “Moto Mod” add-on that would make the Z3 Play one of the first 5G-capable phones on the market. The photos show an attachment that connects to the back of the phone, complete with an antenna “lip” along the top for 5G connectivity. While it would obviously add bulk to the phone, it’s a very unique idea that has the potential to allow Z3 Play users to add 5G capabilities as needed and streamline when it’s not needed.
