Nokia Power User, citing a Chinese FCC equivalent through which the phone has reportedly passed, claims the Lumia 730 (RM-1038) will come with support for 4G LTE; Nano SIM, Qi Wireless charging, and microSD card. The site also suggests the height and width of the alleged Lumia 730 will be 134.7mm and 68.5mm respectively; though there is no word about thickness.
The site has also posted a diagram of the alleged Lumia 730 components visible through the rear panel, such as the battery and camera with Carl Zeiss branding.
Phone Arena has also cited an FCC listing for a smartphone with model number RM-1038, which very few specifications, but corroborates those apparently listed on the Chinese FCC equivalent. It is also seen to support NFC.
Last week, the Redmond giant started sending invites for a September 4 event in Berlin, Germany. The company also teased an orange (same colour as the leaked component image seen above) image that said, "Ready for more" and "Join us for more face time."
Microsoft's rumoured selfie-focused smartphone was also reportedly shown off at an internal company meeting by Stephen Elop last month. Recently, the rumoured Lumia 730 was leaked by a Vietnamese retailer - tipping the handset's design, pricing, and specifications.
According to the leaked specifications, the unannounced Lumia 730 is likely to feature a 4.7-inch HD display and will come with dual-SIM support. Under the hood, the anticipated selfie-focused handset is expected to be powered by a Snapdragon 400 processor alongside Adreno 305 GPU and 1GB of RAM. It would sport a 6.7-megapixel rear camera and would feature a 5-megapixel front-facing camera, which will be the highlight of the rumoured device.
In addition to the rumoured Lumia 730, Microsoft is also said to be working on another Lumia smartphone flaunting the "Nokia by Microsoft" branding, dubbed Lumia 830.
