I think there is a misunderstanding in this thread.
There’s nothing wrong with Android 9 and we are fine with it. Not much difference to Android 10 to be honest.
What we have an issue with is a lot of very badly made A9 and A8 devices that are very cheap and hopeless…
These two Lokmat models are not bad and they are supportable. Like the LEM P and the Prime S.
There is a separate thread about the bad devices out there
Anyway, one thing that we do point out - even if they are good A9 devices - is that flashing firmware is not so easy and the unisoc sprd chipset is not as friendly as MTK chipsets. As @G1NT0N1C mentioned, MTK devices are just a whole lot easier to fix.
The user experience on both the types of watch is almost exactly the same.
So no, there is nothing wrong with Android 9 when it has been used properly.
One thing to note is that the api is getting old in Android 9 and even 10.
Many app developers are now leaving the older versions of Android behind and focusing on the new generation.
Just FYI.
