• Following a similar large update for the Galaxy S24, the Galaxy S25 series in Europe has received a May update exceeding 1.2GB in size for the Ultra model, with the changelog vaguely citing "improved device usability" and no mention of a new security patch.
• This substantial update, which is currently limited to European users on One UI 7 (excluding One UI 8 beta testers), is speculated to lay groundwork for upcoming features or enhance One UI 8 stability, given its size and lack of a security patch update.
• While the reason for this large, region-specific update remains unconfirmed by Samsung, possibilities include addressing local regulatory software requirements or preparing for future feature rollouts; further information is awaited.
