Welcome to Vodafone Community
I've read on various forums that One UI 2.5 update for the Galaxy A9 (2018) has already been released. Does anyone know when or if it will be available for my phone please?
If the phone was supplied by Vodafone UK then it's classed as a Branded phone.
If the phone was supplied by Samsung then it's an unbranded phone and once an update if eligible for that phone model becomes available it'll shown in Settings and Software update. Sometimes using Samsung Smartswitch can show an update.
Updates are sent out via Samsung via region dependent, phone model and build and serial number.
Current Phone > Samsung Note 20 Ultra 5G - SM9860 Snapdragon.
Samsung One Ui 3.0 / Android 11.
