My s20 ultra 5g has not been got a single software update or security update since 1 February 2021. Can I get some advice why this is happening. I have factory reset my phone and nothing. Try contacting Samsung and they not helping. Any thing would be great. 
Thanks

The code at the end is XSG, this is the CSC for United Arab Emirates, which means your phone was originally made for use in that country. It won't pull through OTA updates if it is being used in another country, that is why you haven't received any updates here in the UK, I assume you are in the UK as the other codes BTU are UK.

@Ksmy89 yes I am from the UK. How do I fix this problem? Without flashing the phone. Can't lose my data😂

I have changed a phones CSC code before using SamKey which you have to buy credits for but if you are still on Android 11 there is a free method you can try with Google phone dialler app - you need to change it to BTU code.

In both cases, make sure to back your phone up in settings and any photos etc to an sd card or PC first!

Thank you ksmy89 and everyone for you help. It's it easy to change the BTU code via the phone dailer app and will I lose my data? Will this allow me to get genuine software update from Samsung and nothing rooted

Sorry my mistake, its android 10 you need to be on to use the Google phone dialler method. So SamKey will be the only way to change the CSC code so you can then get regular and genuine OTA updates from Samsung. SamKey is a windows program so you'd need access to a PC and as mentioned before buy credits, I got mine from eBay previously.

Another option would be to use Odin to load the latest software but you would have to do this manually every time a new update is released.

I guess the other option is to treat yourself to a new phone 😁 it's best to buy direct from Samsung or a network provider, or even retailers like currys, very, John Lewis etc to save having this issue again in the future. Anyone can sell on eBay and amazon.
