Alcatel's flagship Idol 4S and smaller Idol 4 pair slick looks with a customisable button found on the side of the phones called the "boom key".
This here is Alcatel's brand new flagship smartphone, the Idol 4S. As well as some surprisingly slick style, this phone packs a 5.5-inch display with a 2,560x1,440-pixel resolution, an octa-core processor -- and some sneaky tricks up its sleeve.
It's coming to Europe in the summer, followed by the rest of the world later in the year. Prices aren't yet known, but Alcatel typically puts its phones squarely in the "affordable" category, so I'm hoping to see a reasonable price attached.
You can set the key to launch the camera, to take photos, or to launch a pre-set app. Set it to launch Instagram in an instant if you want to make sure you can post images of your food before it goes cold.
The Idol comes with a virtual reality viewer in the box. Slot your phone inside and hold it up to your face like Luke here and you can watch VR-specific videos, including those cool 360-degree videos that keep cropping up on Facebook and YouTube.
