It's hard to do it with a phone. Sometimes when I try, the moon mistakenly looks like a balloon or a golf ball. You'll have better luck if you use an app like Yamera and an extra lens that clips straight onto the phone which will allow you to zoom in closer.
No, nothing seems to work for my phone. Getting a good shot of the moon is difficult to do with only a smartphone. Some may be able to do it, but those would be the expensive models. In that case, buying a cheaper camera instead might've been better.
