How to improve camera quality of Lenovo s820?

I just bought lenovo s820 and satisfied with the quality of the camera. But there's one problem. When taking video, there's no problem if took it without moving. But if I want to move to the left and to the right, the video stops for awhile. That makes the video not smooth and seems like there's some transition going on. Is there any solution how to make the video smooth? For more detail, check this youtube video. It is 100% the same. Please help me admin!

Try installing camera 360 but its not gonna magically improve the quality of the camera perhaps the problem is the camera of the phone itself i experienced this problem in my phone too cherry mobile flare s the camera was tagged 8 megapixels but it looks like 2 megapixels… Try to compare the results to the other phones which is the same of your model maybe there's a problem in your phone that is covered by the warranty
