ZTE is pushing system updates to its Axon and Axon Pro smartphones. Both phones gain a camera quick-launch button, Google security patches, Qualcomm modem patches, and better support for MetroPCS. The Axon's camera should zoom more effectively, and the Axon Pro's camera will focus faster in low light and deliver better white balance. The Pro also earns T-Mobile WiFi calling. ZTE said the system updates will be delivered over the air.
