OnePlus X vs OnePlus 3: Our Recommendation

Ending our comparison between the OnePlus X vs the OnePlus 3, we conclude that the newer OnePlus 3 has the edge when it comes to performance specs, thanks to its above-average 6GB of RAM. The OnePlus 3's 16-megapixel main camera also looks more-capable of taking high-quality photos compared to the OnePlus X's 13-megapixel rear-facing camera. Here is the summation of our thoughts:

  • While there is no difference in the resolution of their selfie cameras (8-megapixel), the OnePlus 3 and its 16-megapixel main camera would be the best choice for those who love snapping day-to-day photos.
  • Even though it seems simpler in many areas, the OnePlus X is still not that bad at all, diverging only marginally from the OnePlus 3, and therefore, its price ( ), depending on how it appeals to you, may make the X an overall better choice.
