The only thing I have a problem with is people saying that it is widespread when it isn't. I would also say that with the internet being what it is, you can't just take people at their word either. If it is truly an issue for you, I think you should definitely hold the company accountable to fix it. But at the same time, who's to say that some people didn't also crack it themselves either by accident or even on purpose and don't want to pony up the money to repair it? Anymore, you really can't take anyone at their word because it seems more and more people have no problem lying to get what they want, which is cold comfort when you actually have a problem but people are reluctant to believe you. But it's the world we live in.
I decided not to buy 6P when this "story" broke because I google searched it and many many sites reported that the backs of the 6P were cracking. However, once I started reading the actual articles, it quickly became clear that everyone was just rehashing the same reddit over and over again. That's what's frustrating. The people who experienced this issue should be able to get a new phone. But it's not right that the extent of the cracking was grossly exaggerated to the point that Google/Huwaei may lose sales for an issue that is not nearly as widespread as implied.
