Xiaomi’s Mi Note 3 is a mid-range smartphone considering that it packs a Snapdragon 630 chipset but the device has all the qualities of a flagship model. First, it features the same design as the flagship Mi 6, except that it has a bigger size. The Xiaomi smartphone was recently revealed to have pooled an impressive score of 90 points on DxOMark’s benchmark test. That camera has been put to test in real life use and the Mi Note 3 comes out unscathed. 
The test is meant to determine the image stabilization property of the Mi Note 3 in comparison with that of the iPhone X, the Samsung Galaxy S8 and the Huawei Mate 10. The short clip shows for different videos captured by the quartet of a lady flipping through the pages of a book while sitting inside a moving train. Only the Mi Note 3 and Galaxy S8 are able to withstand the shakiness of the train and still films the scene in a stable manner. That is likely due to the presence of Optical Image Stabilization (OIS) on the device. On the other hand, the Mate 10 Pro and iPhone ‘s recordings were affected by the vibration generated by the fast-moving train and thus the videos were shaky all through. What makes this all becomes confusing is that all four smartphones come with OIS! So, we can’t really say why there is a difference in their performance.

This does not in anyway mean the Mi Note 3 packs a better camera, all three models are flagship phones and have better DXOMark’s score than the Mi Note 3. So, we can’t verify if this video test was actually carried out with the mentioned models. That is not to say the Mi Note 3 cannot deliver stable videos in rough terrain. It can, due to teh 4-axis Optical Imaging Stabilization (OIS) it features. But we find it difficult to believe the iPhone X and Mate 10 Pro will perform that bad. You can watch the video from here.
