I don't really understand how one should consider a phone's design is 'good', while the trend is going nowhere; same brick design from all manufacturers. I can say other things regarding its design's functionality, though.
First of all, I kinda made an oath that I won't buy any phone with a screen notch...or punch-hole camera. Its just plain lazy design, I think. Aquos & Mi Mix 1 put the front camera in the bottom bezel is good enough. Meizu 16s put the front camera inside a really thin top bezel, and I say that is brilliant and going forward in term of engineering. I had bad experience with Meizu's software (and 16s has higher price tag), Redmi Note 7 has issues with display, and other devices with similar price tag & hardware performance essentially sport a notch, so I get R3Pro after my Zenfone 2's unexpected encounter with concrete.
I like the position of the back camera since it looks more natural compared to horizontal or center arrangement. Does the phone wobble when I put it on a flat surface? I don't know because I totally don't care (ps: it's doesn't, if you put on the included silicon case).
Finally: the buttons. Realme separates the Volume Up & Volume Down triggers, which is good; and also put the Volume buttons in the opposite side of the body as the Power button; which is even better. I won't need to fiddle around trying to find the Volume buttons. Also, this design will mean that later when the phone got custom ROM development, I can just use 1 hand to 'squeeze' the phone to trigger both Power+Power Up or Power+Volume Down, to access the recovery.
