Are there OTA updates that are safe and good to be applied to NON EU version. That is not Android 10 ?

Hi, on the official Blackview website they sell new BV9900pro updated to Android 10 for EU and NON EU version.
Is there a stable Android 10 update for NON EU version or  are those phones new hardware revision that do not have all problems mentioned here in this forum with Android 10?

On the official website  https://store.blackview.hk/en/buy/bv9900pro say: Newly Updated: BV9900 Pro is Android 10.0 Now!
It shows that new phones are sold with Android 10. Why do you state to Not upgrade to Android 10 because it is not stable?

Did you upgrade to Android 10 . Is the Call Echo still there on Android 10 ?
