The G4 Play has a 5-inch display at 720p HD, a 1.2 GHz Snapdragon 410, and an 8-megapixel main camera at f/2.2. The battery holds 2800mAh and supports rapid charging, but the charger is not included with the phone. Other features include LTE, Bluetooth, GPS, WiFi, sensors, and micro USB. Motorola said the G4 Play is available for preorder today from the web sites of Amazon, B&H, and Motorola. The phone sells for $149.99. Verizon Wireless plans to make the G4 Play available to its prepaid customers in the coming weeks. Last, Amazon plans to offer a Prime version of the Moto G4 Play for $99.99.
