The Z3 Play runs Snapdragon 636 chipset - a welcome improvement over the 626 chip. There is new processor with eight Kryo 260 cores and a new Adreno 509 GPU. And now both the 32GB and 64GB models will come with 4 gigs of RAM.
The camera department has got an upgrade, too. The main camera at the back keeps the 12MP sensor, once again sitting behind f/1.7 lens, but also receives a secondary 5MP snapper to help with those trendy background effects. Dual-Pixel autofocus is available, as well as the dual-tone LED flash.
