The camera on the Huawei p30 lite is protruding, so I'm always afraid it could break if I put the phone on its side.
To what extent is this fear justified?
There's glass over the camera
Then just get a cell phone case.
If you throw it to the side or pop it, you are still afraid so you can get a cover
So what I see in pictures looks like you shouldn't have to worry about it. Hardware is or is built anyway so that it lasts long enough. So I would say that it is not a problem.
You don't have to be scared, but you should get a shell that is thick enough to eliminate this annoying problem.
