LG G4 cannot replace buggy phone?

[AC Question]

There's the issue of random resets, overheating, looped boots, and broken wifi with the LG G4.
LG has claimed that those problems were their mistake and therefore they would replace all phones with that issue.
However, I had broken the screen of the phone and so LG could not replace my phone, and my carrier, Sprint, has a contract of lease with the phone so I would have to buy a replacement phone and pay out the useless G4 after the contract. Is there any way to repair the phone with this problem?

Have the screen repaired, then have the phone replaced. They're not going to eat the screen replacement cost (nor should you expect them to).
