If you did own them, you would know that the screen isn't made of plastic. You also wouldn't think they were unwieldy, unless you are the type of person who likes smaller phones like the iPhone Mini, etc. Which, if that were the case, it wouldn't make sense to be buying those foldables to begin with. How does the crease bother you? You can barely feel it on those phones, and I've owned both the ZF7 and the Find N5, and you can't hardly ever see it unless you have lights over your head constantly or you're outdoors constantly.
