According to the translation of said post, Pete Lau "believes" that the OnePlus 5 "is the thinnest flagship phone." It's not clear if he talks about all flagship phones on the market, or just about OnePlus flagships. However, we can certainly assume that the OnePlus 5 will be thinner than the 7.35 mm OnePlus 3T (pictured above), thus becoming the company's skinniest high-end smartphone to date. The 6.9mm-thin OnePlus X doesn't count, since it wasn't a flagship model.Pete Lau also seemingly says that OnePlus didn't have to make compromises related to the user experience in order to build a thinner device. Oh, and he's already using the new phone - but that's hardly a surprise.Of course, until we know the phone's dimensions, we can't really compare it to the OnePlus 3T (or to any other flagship out there). We'll just have to wait and see exactly how thin the OnePlus 5 is once it's officially announced.source: Weibo (automatic translation not available)
