Probably difficult to say how easy it is to break, but I once had an unexplained break of a camera lens on an LG G4 I owned a few years back. I have always ordered a Dbrand camera skin for the camera lens of every phone I have owned since. It's probably overkill, but for a few bucks it gives me piece of mind against breaks and scratches. Of course, since I use my phone without a case, my risk of breaking the screen is far more significant, but for a cost of less than a cup of coffee and virtually no impact on the look or feel of the phone, the Dbrand solution is perfect for me.
