Apple’s next-generation “iPhone 5S” will reportedly feature an upgraded 12-megapixel camera with improved image capture capabilities in low light. The report comes from Tinhte.vn, which has on occasion accurately reported details of unannounced Apple devices in the past. The Vietnamese tech blog names Wonderful Saigon Electrics, the Vietnamese arm of a China-based mobile camera component supplier, as its source. No other details were provided, though Tinhte.vn notes that its source at Wonderful Saigon Electrics accurately stated that the iPhone 5 would include an 8-megapixel camera last year while rumors of an upgraded 10-megapixel module were circulating. Apple’s iPhone 5S is expected to launch this summer with an upgraded processor, a new camera and possibly new color options.
