How can I get one ui 4 on my S21?...

[DaraG]

I have navigated to the update page and there's no available updates, not sure how to get it

One UI4 was put on hold by Samsung for the S21 Series due to a number of issues.

I believe it is slowly being rolled out again but it will be over a number of days / weeks.

Updates depend on your device's CSC code, (Country Specific Code).

To locate this, go to...

Settings > About phone > Software information > Service provider software version (see screenshot)

What update are you currently on?

Does this make a difference?

This is useful, thanks 👍

@DaraG 

Your screenshot shows a mismatch of CSC codes which would seem to prevent you receiving updates.

OXM = Non regional CSC code... to be expected

BTU = Samsung non carrier branded CSC code for U.K.

EUX = European, non country specific code

O2U = U.K. carrier code for carrier branded network O2 devices.

Put simply, your phone does not know which firmware you should be receiving.

Try the following...

1. Turn off WiFi.
2. Remove SIM.
3. Power Off (not reboot).
4. Insert SIM.
5. Power On

If this does not work you may need to contact a Samsung Service Centre.
