Nokia, Finnish mobile manufacturer will try to bring the Windows 8 experience to all Lumia series phones with its upcoming Windows Phone 7.8 upgrade. It has been reported by director of smart devices at Nokia India that it's not possible to upgrade the hardware on the devices, to accommodate the new upgrade we will be looking at bringing the Windows 8-like look and feel to our Lumia range of devices with the Windows Phone 7.8 upgrade.
Common set of features for seamless, hiccup-free interoperability is shared between the Windows Phone 8 and Windows 8 operating system which has been built using the same core. They also share some more common features in networking, media, and the web browser. They have to face the hardware limitation which will still apply to upgraded Lumia devices. They are expected to miss out on the interoperability front.
Soon Nokia will soon start releasing application upgrades for all existing Nokia Lumia devices. Another upgrade include Nokia live radio, an online song streaming service; upgraded Nokia Drive application with traffic details; the camera application with a set of new functions like best group shot and more. Lumia devices will also get the much awaited Wi-Fi tethering feature which permit users to use their devices to power the internet needs of their other portable devices.
