The Oppo F15 is the successor to the Oppo F11 and features a new, slim design, USB Type-C port, an in-display fingerprint sensor and four rear cameras. The new finish looks nice and the phone feels light to hold. The 6.4-inch AMOLED display gets bright and has good sharpness, thanks to the full-HD+ resolution. 

It's powered by the MediaTek Helio P70, which is a little underpowered for a phone at Rs. 19,990. There's also 8GB of RAM and 128GB of expandable storage. The F15 runs on ColorOS 6, which is based on Android 9 Pie. General app pperformance is good and the phone handles games fairly well too. The 4,000mAh battery also offers solid battery life and there's fast charging, through VOOC 3.0 Flash Charge. 

The primary 48-megapixel sensor captures good, pixel-binned photos but you cant shoot at the full, 48-megapixel resolution. The 8-megapixel wide-angle camera has autofocus, so it can be used for very close-up shots. Low-light performance is a it inadeqate and there's no support for 4K shooting.
