As per the entry at Camspeed, it has a 5 MP camera without flash, which is in sync with above press render leaked by evleaks. This may explain how Nokia may be able to keep Lumia 630’s price quite low, as hinted by Zauba records.
The RM-974 revealed at Camspeed is naturally running Windows Phone 8.1 and the version confirmed by Sofica is 8.10.12324.0.
