In spite everything it is going through right now, Nokia continues to develop upcoming Nokia phones for 2014, and one of it has recently been leaked online. 

In case you are a big fan of the Lumia 520, the best-selling Windows Phone ever, you may want to check out its upcoming successor, dubbed as the Lumia 530. 

According to a report by GSM Arena, the device shows up in a Vietnamese retailer website, though nothing is yet to be made official. 

In previous rumors about the Nokia Lumia 530's specs, it only packs a slight upgrade to the original, mainly in order to keep the price down. 

Alleged specs of the Lumia 530 include a 4-inch ClearBlack display with 480 x 854 resolution, a quad-core CPU clocked at 1.2GHz, a Snapdragon 200 chipset, but only 4GB of internal memory and still 512MB of RAM. 

One of the upcoming Nokia phones for 2014 will also retain the Lumia 520's 5MP camera, as well as get similar dimensions. The device will be dual-SIM enabled as it appeared in an FCC certification document almost a week ago.
