As a buyer trying to decide between a LG G3 or LG G4 or Samsung S5, I have been reading online that the LG G3 has a defective case design that results in cracks that are not a result of drops and abuse.

Has LG re-engineered and redesigned upgraded NEW parts that will NOT crack once the fix has been applied?
Or, is LG just replacing defective cases with the same defective parts that will eventually crack again?

What is LG's current process and timeline and customer costs associated with this repair?
If taken to a Sprint corporate store, what is Sprint's current process and timeline and customer costs associated with this repair?

Thank you.

PS
I refuse to use a case with the G3 because it is already TOO WIDE from left to right.
70mm or less should be the max width of these phones.
