This question has become actual due to two reasons. First, a few days back we have heard Xiaomi may switch to Samsung for curved displays. Today the LG G6 was displayed to large masses, and there was no curved displays. These two cases caused a huge stir among Mi fans. I guess other smartphone makers but Xiaomi are interested in it as well. So the Korean giant has had to lay its cards on the table. It turns out, the Korean manufacturer has held a few tests. And according to repeated tests it’s become known curved display handsets are not suitable for long time holding. Thus hands get tired the way faster when holding curved-screen phones than when handling flat-screen smartphones.
Other than that, LG also claims curved screens are fragile. However, this explanation is not satisfactory, because the company still uses outdated Corning Gorilla Glass 3 protection. Users wonder why it doesn’t switch to higher versions of this technology.

So we can conclude, LG doesn’t use its own-made curved screens in its flagships because this technology affects the usage duration. If think, there is a grain of truth.
