How can i use my camera mobile phone as webcam in messenger? Is it possible? If possible, where can i download that software for free?|||It really depends on the phone. You may want to check the user Manual or the Manufacturers website. The key indicator as to whether it might be possible is if it has some sort of USB connector. Without that, it is not likely possible. And if it does have a USB connection it may need a specialized one that only connects to that type of phone. Which means it will probably cost about $20 or more. And it may still have to use the Phones batter which mean it may not stay powered very long. Well that is unless you have the power plugged in at the same time.
