In this guide, we will show you the steps to install the latest S25 Ultra One UI 7 port based on Android 15 on your Galaxy S23 Ultra. Back on the heels of Pixel, the South Korean giant also modified its update schedule and gave us the goodies that we were all waiting for- 7 years of OS upgrades. But it seems that it is way too much to handle for the OEM as it isn’t even able to roll out a single update in a timely manner. The perfect example of the same is the latest One UI 7 update of which only its flagship has been beneficiary.
Well, many are speculating that it has intentionally been done by the OEM to push the sale for the S25 Ultra, because apart from that there doesn’t seem to be any differentiating factor between this device and its predecessor that will convince the users to do the upgrade [if you would like to call it one, for me, it’s more of a downgrade, thanks to the removal of the Bluetooth from the SPen among other controversial changes implemented in this latest flagship].
However, someone please tell Samsung that even this delay wouldn’t be enough to convince users to shell out hefty bucks to perform the upgrade because sooner or later the update will land on the S24 series and then, there will be no persuasion from the power to perform an upgrade.
And the icing on the cake? If you are ready to step into custom development, then you can welcome abode the latest One UI 7 port based on Android 15 from S25 Ultra onto your Galaxy S23 Ultra. So without further ado, let’s show you how this could be carried out.
