Nokia showed off two phablets at the UAE launch. Both the Lumia 1520 and Lumia 1320 feature 6in (15.2cm) displays, allowing extra rows of apps to be displayed on their home screens than possible on smaller models.The firm said that the extra space would also make it easier to use the phones’ touchscreen keyboards, suggesting this would appeal to business users who used productivity software. A new Beamer app will allow the phones to stream the contents of their screens onto to a web browser on a separate display. It works by sending data via Nokia’s computer servers.Another new app – Refocus – lets owners determine which parts of a photograph are in focus and which are blurred after it is taken. The phones achieve this by taking a series of images in quick succession at different focus lengths rather than replicating the light field effect captured by a Lytro camera. It’s clear that the market is heading towards photography with mobile phones.
