LTE technology is usually divided into two distinct camps, FDD-LTE and TD-LTE, that might as well exist in two different worlds: own a device using one and you can't access the other. ZTE is bringing some harmony to 4G through the Grand Era LTE. The smartphone can connect to both LTE formats on China Mobile Hong Kong's newly dual-mode network, keeping locals in the high-speed zone no matter which 4G format is available. As our friends at Engadget Chinese discovered in a hands-on, however, it's not quite seamless at this stage. Subscribers have to reboot to switch networks, and the Hong Kong take on TD-LTE access doesn't upload as quickly as its FDD counterpart. Even with those bubbles burst, the Grand Era LTE is still a solid phone in its own right, touting a 4.5-inch 720p screen, a 1.5GHz dual-core processor and ZTE's relatively light Mifavor interface sitting on top of Android 4.0. Check our video after the break to get a taste of the phone and the network -- although the clip is in Cantonese, the results are universal.
