The N4 series of 360 mobile phones is divided into the N4 and N4S. The battery capacity of the latter is much higher than that of the former. Recently, it seems that the f4 series of 360 mobile phones will repeat this mode. On the website of the Ministry of Industry and Information Technology of the People's Republic of China, we can find a new product suspected to be 360f4S, model 1603-A03.

From the visual perception of the back cover, the 360 mobile phone f4S may use a metal body. Previously, the 360 mobile phone f4 was only a plastic body. However, the front panel design is more like the 360 mobile N4S, because a front fill light is also introduced. The N4S of 360 mobile phone is equipped with a 5000mAh large battery, while it is rumored that the f4S of 360 mobile phone uses a 5.5 inch 1080P screen, an MT6753 processor, a 3GB RAM+32GB ROM, a front 5 megapixel camera, and a rear 13 megapixel main camera. The battery capacity is 3920mAh. The Android 6.0 system is pre installed, and the price is close to the previous one.
