Your software is up to date.
Current version: G998BXXU3AUDA / G998BOXM3AUDA / G998BXX3AUDA
Security patch level: 1 May 2021
Just as I thought, this device was originally on European code LUX for Luxembourg and has been re-flashed by a re-seller with a generic engineering firmware, G998BXXU3AUDA, which was never released for the stock Samsung, U.K. models on CSC code BTU, or Luxembourg for that matter.
I have come across this on a number of other forums and you will never receive an OTA, (Over The Air), update on this device with such a CSC code mismatch as it is not recognised by Samsung.
You can no longer change your device's CSC code by using sites such as SamKey.
You therefore have 2 choices...
- 1. Download and update the latest U.K. firmware manually, using Odin. This will need to be done each time there is a U.K. update.
- 2. Return your phone to SmartPhoneStore (UK) and demand a refund.
