    Updated to Oxygen 12 and 5g no longer works. I'm with 3 mobile in the UK. 5g working before update. Now only able to get 4g+Says it is enabled when selecting preferred network type.. Is this a known bug with Oxygen OS 12?

    Thanks

    It's a known bug and one of the main reasons not to upgrade in the UK.


    I'm on EE 5G. I bought this phone specifically because it was a 5G phone


    Now it isn't a 5G phone with the recent botched upgrade.

    The 5G issue does not apply for all though. Not sure what differs form the guys that has it working and those that do not.

    I'm yet to see anyone in the UK without loss of 5g.

    Try to change sim card to slot 2. 5g works perfectly for me with sim slot 2. In sim 1 only 4g.
