So all in all. The fix would be stronger/stiffer blades to combat flexing.
I wonder how that carbon fiber blade sar linked would perform.

That's my guess as to what's happening - yes. I don't know if it helps to tip the drone forward as you put it in? - Or a maybe a small rubber-band put loosely around the props to keep them east-west would help??I am always paying attention to how I pack it in the case and with all that I just looked at my logs the other day and I can see my rear left motor spinning at almost 3000 RPM more than the right one. Also, I’m guessing part of the problem is that it might happen that the prop moves slightly as you put it in the case and you can’t really see if it’s under the belly of the drone.

Some are easy to understand like the motors rpmbut I was trying last night to detect vertical and horizontal speed and could not locate them
I think you meant to say, "If on takeoff the front goes up before the rear ...".If on takeoff the rear goes up before the front, change the props.
A few simple checks before you fly and the issue is unlikely to occur. People who fly radio control fixed wing or helis spend plenty of time doing checks before taking off, because it means you're not going to be surprised by something loose or not fitted correctly causing a crash. Drones really shouldn't be any different - and my Mini cost more than any of my helis or fixed wing planes, so I feel I should treat it with perhaps more respect with regards to storage and pre-flight checks.
If you look at the rear props and they look any different to the front ones, then change them. If on takeoff the rear goes up before the front, change the props. Fly gently for the first 5-10 minutes to see if it's behaving or sounding unusual, and if it is land and check it over. Keep it in VLOS and if it looks to be doing something other than what you expect, gently bring it down and back to home.
Enjoy flying it, but be aware that it is a complex piece of electronics and mechanical parts and so can go wrong in some circumstances. Read this forum to get an idea of what kind of things can cause problems, and how best to react should they occur. If yours does develop the uncommanded descent issue (and there's nothing to suggest that everyone will experience it), then understand what you can do to minimise damage and get it back safely, then change the props and get back in the air.
At some point either DJI or some third party will release better props. It's only been out less than a year and seems to have been exceptionally popular. Many people have been flying regularly since last year with no issues at all, so don't assume that you'll experience them.
Looking for prop damage has always been an important pre-flight check but, in this case, the problem is that the deformation isn't at all obvious with the props on the motors. And flying gently to begin with often doesn't manifest the problem. Better props is definitely the only real solution here.
I think you meant to say, "If on takeoff the front goes up before the rear ...".
Yes, they will release them soon. Master Airscrew STEALTH Props for Mavic Mini?
I was wondering if there are any more uncommanded descents after upgrading to 1.0.0500
and replacing props if indicated by motor speed error ESC?
I searched the forum but couldn't find any referrals.

I'm starting to suspect that the motor axis angles actually do have influence on how the props become deformed. It has to do with the way the props mesh when stored with the arms folded.[...] in this case the problem is clearly caused by deformed props, not the motor axis.
