Conclusion
At around 350 EUR, the Oppo R15x is positioned as a strong contender in the mid-range smartphone market. It strikes a good balance with its vibrant Super AMOLED display, reasonable performance, and robust selfie camera. However, it does present limitations such as no NFC, no expandable storage, and lower charging speed. For users valuing design, display quality, and reliable everyday performance, the R15x offers a fine-tuned package that satisfies the essential demands without unnecessary gimmicks.
