There was a rumor before that the Lumia 830 would be equipped with the same 20 million pixel camera as the 930. However, according to the new rumor, the Lumia 830, as a model with a positioning lower than the 930, may only be equipped with a 10 million pixel camera, a Qualcomm 400 chipset and a 720P screen. It is also said that the Lumia 830 may be one of the thinnest Lumia devices ever.
