I just found that my tango tablet's depth sensor is not working as expected in my project. Then I took the depth test as instructed in <https://developers.google.com/project-tango/hardware/depth-test> and found the top right area (about 1/4th of the rectangular ) of the point cloud in the screen are always nearer than the others and full of errors. I tested in different lightings and also tested some clean floor area and found similar errors in that area. So what is wrong with the depth sensor?

Thank you so much!
