The Oppo K1 features a plastic body with a 3D injection moulded back, which creates cool patterns against light. The 6.41-inch AMOLED display produces punchy and vivid colours and it also has a segment-first in-display fingerprint sensor. The phone is powered by a Qualcomm Snapdragon 660 SoC and comes with 4GB of RAM and 64GB of storage. The front 25-megapixel camera shoots good selfies in daylight. The rear 16-megapixel sensor does well in daylight but struggles under low-light. The 3600mAh battery easily lasts an entire day on a single charge.
