A new device called the OPPO CPH1925 (or A1s) has popped up on the websites of Russian, Thai and connection-specific regulatory bodies. Like the A1k before it, it has a 2.0GHz MediaTek processor, a 4000mAh battery and a 6.1 inch waterdrop-notch screen. However, this model improves on its pre-existing sibliing with a dual rear camera.
