Nope that's the first time for the R5 (the world's thinnest phone, or was last I checked). The other times were for the Find 7 (which I own), which was, at the time of purchase, the highest pixel density of any phone, though others have matched QHD, but in a (smaller) 5.1 screen.
Just because I'm happy with my purchase doesn't mean I'm a shill. Just trying to make the point that you can't judge every smartphone by the iPhone or Samsung de jour. So many complain about a specific flaw in a specific model, then generalize. Yes, thinner can mean weaker, that's why Oppo made a video of the world's thinnest phone cracking nuts, cutting apples and watermelons, and being run over by a car. If you still think that thin means weak, that's your insanity, not reality.
And yes, I watched all the marketing material and read many reviews before buying the Oppo, since I hadn't heard about them until I was looking for a replacement for my S3. The marketing videos seem relevant to the complaints here.
