The well-received Nokia Lumia 1320 is reportedly about to get its successor in the form of "Microsoft Lumia 1330." Aside from revealing the existence of such a device, the recent report also points to some of the key specifications of the upcoming Lumia device.

According to reports, the Microsoft Lumia 1330 will feature an impressive 5.7-inch display, complemented by 720 x 1,280 pixels resolution. It is also said that the handset will be powered by a quad-core (Qualcomm Snapdragon 400) processor, alongside Adreno 305 for graphics. Plus, the handset will be backed by a modest 1 GB of RAM. Speaking of native memory, the device will reportedly come equipped with 32 GB of internal storage capacity, reports Phone Arena. However, there is no information available at this point to ascertain the expandable storage option.

When it comes to key differences from the current-generation device, the Lumia 1330 is expected to get a bump in the camera configuration. The smartphone will apparently feature a 14 MP PureView rear-facing camera unit and a surprisingly good 5 MP front-facing snapper for selfies. Notably, the original Lumia 1320 houses only a 5 MP rear-facing snapper unit and a 1.2 MP front-facing shooter.

Meanwhile, the Microsoft Lumia 1330 is expected to be announced at the Mobile World Congress event, also known as MWC 2015, in March. It is worth mentioning that the upcoming Lumia 1320 successor will reportedly come pre-installed with Microsoft's Windows Phone 8.1 GDR 2 OS version. Going by the report from Windows Phone cross-promotion network AdDuplex, the Microsoft Lumia 1330 will be released as four different variants. The reported model numbers are RM-1062, RM-1063, RM-1064 and RM-1065.

On the other hand, the mid-range, Windows Phone-powered, current-generation Lumia 1320 is not an ordinary phone either. It comes with a whopping 6.0-inch display, similar to the flagship Nokia Lumia 1520. Other than the humongous screen size, there are not many similarities between the Lumia 1320 and the Lumia 1520.

The current-generation Lumia 1320 features a modest resolution of 720 x 1,280 pixels, whereas the Lumia 1520 comes with 1,080 x 1,920 pixels resolution. Under the hood, the flagship Lumia 1520 is powered by a quad-core (Qualcomm Snapdragon 800) processor, clocked at 2.2 GHz, while the Lumia 1320 employs a relatively inferior dual-core (Qualcomm Snapdragon S4) processor, clocked at 1.7 GHz. Speaking of camera configuration, the noted camera phone Lumia 1520 sports a killer 20 MP rear-facing unit, whereas the Lumia 1520 settles for a 5 MP unit on the rear.
