You still need to get to the app using the side button and then have to press the screen (hard, as ever) for the device to register that you want to command it to do something. Like the Favourite app, there is also a Voice Control app which is supposed to allow you to complete various tasks by talking to it. It's easy to sync the device to the app using Bluetooth, via one-touch NFC (near field communication) if your smartphone has it. The 1.4-inch display features a resolution of 320 x 320 pixels (192ppi) and you can opt to have white text on black or vice versa using the accompanying app, with the black-on-white looking less like a mini Kindle strapped to the wrist. That's great for the benefit of its low power-consumption, but also means no colour, which looks somewhat drab in a device of this type. Indeed it is the first wearable device to offer this kind of display. Sony has opted for an E Ink display on the SmartBand Talk, which is its biggest point of difference compared to the company's other wearables. However it lacks the far better Super AMOLED display and heart-rate monitor of the Samsung. The scale is one of the SmartBand Talk's best attributes, as at 23.5mm wide, 9mm thick and weighing just 24g, it's slimmer, lighter and more subtle to wear than the Galaxy Gear.
