The Moto G4 Plus ditches the trademark bottom grille of the Moto G series for a fingerprint sensor. It’s not a physical button but it is slightly raised to help you find it by touch alone. Moto is updated and upgrade their some features. The sensor can recognise your fingerprints from any angle and apart from a few intermittent misreads, it works very well all the time. The back is mostly flat as opposed to the earlier curved designs of Moto G4 puls models. The 16-megapixel sensor is accompanied by a dual-tone LED flash and a laser autofocus system, which is a substantial upgrade.
