But here's the thing, the fault didn't appear immediately after breaking the lens, it happened later.
Now, we know for a fact that the fault is with the manufacturer, because they have admitted that it is their fault. As they have proven themselves that it is NOT the fault of the consumer, then LG should replace it.
This is how you come across at the moment:
I fell down the stairs a couple of years ago. So if I had a bone condition that I was born with, and my leg suddenly broke, it MUST be the fact that I fell down the stairs 2 years ago, and I shouldn't get treatment for this unrelated break because it was my fault for falling down the stairs, even though that incident has nothing to do with the actual problem.
Also, drops basically never cause faults to the mainboard, because the body of the phone crumples before any shock can reach the mainboard. This is no different with the G4. It's usually a crush that causes mainboard damage, like being ran over or something.
