I'm at a complete loss here. I keep hearing everyone talk about receiving the 'new' Android 12 update yet I haven't even received the first update, let alone the recent bug fixes. I have attached screenshots of my service provider software version below. Would be greatly appreciated if anyone could help, samsung support just keep binning me off and aren't being very useful

Where did you purchase your phone and which country are you using it in?

Your screenshot shows a CSC code mismatch.

The original CSC code for your device, S21+ 5G, is MXO = Mexico.

It has since been re-flashed with the generic European firmware, EUX, and is running the old AUJ7 firmware from last year on Android 11.

With such a mismatch, you will not receive OTA, (Over The Air), updates from Samsung or via Samsung's PC suite, Smart Switch.

I am given to understand that 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 firmware for your location manually, using Odin. This will need to be done each time there is an update.
  • 2. Return your phone to the vendor that you purchased it from and demand a refund.
