The camera software can only be used with a phone. With tablet (new, 11 inch, Lenovo), works but cannot be used. In the vertical position of the screen, only the area with the image is visible, and the bottom is cut off. It cannot be moved to be used. In Landscape, it switches to Chinese, and this cannot be changed even if you select English. Here only some upper part of the image is visible. With a phone, it only works from close range, maybe up to a meter. At a greater distance, several meters, it shows random, non-repeating values (it is set to 5 meters in the settings). I try it: It's 16 degrees outside. I pointed it at an outside wall, it read -10 degrees (minus ten ?? and it wavered). moved aside, then came back. It was already showing +7 degrees. Absolute random numbers shows, very far from the real +16. The camera is only useful up close, for frivolous things.
