A new 5-inch Lumia spotted online
RM-1090 has a reported screen resolution of 960 x 540
The FCC database revealed an unannounced Lumia device codenamed RM-1090. Details about the handset are scarce. We learn that the 1090 has almost identical size and dimensions as the Lumia 830 and a possible 5-inch display. The upcoming smartphone measures in at 139.9mm x 71.1mm and works with two SIM cards.
AdDuplex also spotted the same device back in August this year. The phone has been seen in Asia which corresponds to the recent FCC document submission in China. According to AdDuplex, the phone has the low screen resolution of 960 x 540, while FCC database reveals the phone has a new battery model BL-L4A , DUAL SIM, Bluetooth, WLan, and the following frequencies GSM 850, 900, 1800, 1900, Band 1 and Band 8.
If the information about the resolution is correct (we hope is not) we are talking about a cheap class Windows Phone. Otherwise RM-1090 sounds like a successor to the Nokia Lumia 1020.
