In 1979 we were all told to poke a pinhole in a heavy piece of cardboard. Shut one eye and look at the eclipse through the other eye. What happened to that advice. It worked then, should work now.
You weren't supposed to LOOK through the pinhole. The idea is to create a projection camera - the light of the sun goes through the hole and creates of shadow of the eclipse onto a second piece of paper/cardboard.
As for the cameras, per NASA the iphone and android camera lenses are too small to let enough light in to hurt the sensor. A straight digital camera can be damaged. And if you take photos via an eyehole, you can damage your eyes.
The other issue is that the camera will most likely end up not being able to properly expose for the image and won't be able to zoom far enough in and all you'll see is a bright glob instead of the eclipse image.
