when I turn on my camera it says lens obstruction

Juanita Gonzalez, this is most likely caused by a stuck lens. These errors are more common with an extended lens, but can also appear in a retracted lens. Take a look on here to see how to deal with it. It will be the same for most brands. If this does not work, you may be looking at replacing the lens itself. Since you did not tell us what model your camera is, we can not provide any further details with that. Hope this helps, good luck.

How about sell us a good product. Same issue with my Kodak pixpro az401
