I've tried many, many styles of cases including every one mentioned above and found that the solution to front flimsiness is an integrated screen protector. Every case has a slight offset so I'd guess Oppo provided incorrect specs to aftermarket case makers. After donating so much money to Amazon, Shopee, Lazada, Temu, and AliExpress, this is the one I settled on: https://a.co/d/02lZZnRl It has the thinnest hinge protector that's satisfyingly spring loaded; snaps on to the phone without adhesive; fits without removing the factory front screen protector; has adequate magnets which add minimal thickness to the back; and has a camera cover which doubles as a stand. If you go with this case, I recommend removing the glass camera cover because it affects picture quality when it inevitably acquires smudges and, stupidly, doesn't open far enough to clear the camera's field of view. Just carefully pry out the glass which is adhered to the metal folding ring (leaving the ring in place) and run a separate glass protector for the camera module. Best of all, this case's front has the least offset -- at <1mm, it's barely noticeable. You don't have to overpay for this case on Amazon. It's also sold on the other sites so do price shop for wherever you live.
