Firmware variations? - Samsung Galaxy A51 Questions & Answers

Why on sammoble does our phone have so many firmware release up? For example i crossed flash hong kong firmare that ends in B4 that was released on march 8 and just yesterday on march 14 samsung released older firmware with last 2 digits in A8 and also release B1 for some countries. I always flash the latest firmware via Odin regardless of what Country. In hopes of better stability and security. Why does samsung do this?( at present time march 16 the newest one is HongKong ending with B4) and it is totally bug free,like even the battery performance is 100 times better(3 days with low to medium use) any thoughts?

Dear all
If anyone can help
My phone axon 10pro 5G model A2020N3 pro saudi arabia version
I didn’t receive any update and stuck in android 9 with september security patch
How i can update or sideload the correct version?
Thanks
I have the 4G version (A2020G) and I think I only ever got one update over OTA. All the other updates I downloaded them from the ZTE website as they became available including the latest V2.5 with the June security patch.
ZTE already has a reputation for horrible OTA updates. I remember on my Axon 7 was the exact same story. Only ever got one OTA, all the others were installed manually.
If you can help for the suitable firmware from their site i will be appreciated
I found one firmware for open market same model A2020N3 pro is it safe to sideload it ?

My Hong Kong N9860 is stuck on November security, despite receiving an update in December.
According to the firmware list on Sammobile there should be a December update available for your model for the past week. Have you performed a manual check on Wi-Fi to see if you can force the new firmware to download?

If your Note is not updating and is not modified I have no idea why. Time to contact Samsung support, perhaps.
