Samsung Electronics began a global rollout of the free One UI 8.5 software update for millions of Galaxy smartphones this month [1].
The update arrives as the company seeks to standardize security and performance across its diverse hardware lineup. By extending new features to older devices, Samsung maintains the longevity of its ecosystem and ensures that users on legacy hardware remain protected against emerging threats.
The rollout, which started in mid-May, targets a wide range of devices to deliver security enhancements and performance improvements [1], [2]. Some reports indicate the update is currently reaching Galaxy S23 and A-series phones globally [1]. Other reports suggest the rollout began with the Galaxy S25 [3].
"Samsung's One UI 8.5 rollout is now reaching Galaxy S23 and A-series phones globally," Jay McGregor of Forbes said [1].
Security remains a primary focus of the release. Yahoo News Malaysia staff said the update brings a new level of security and privacy to millions of Galaxy owners [3]. This focus comes amid reports of technical instability in previous patches. TechRepublic staff said the update may bring stronger security controls as some users reported battery drain and overheating after recent patches [2].
There has been some uncertainty regarding the specific features being ported from newer hardware. Earlier this month, reports suggested Samsung could bring a specific Galaxy S26 camera feature to older phones [1]. However, more recent updates specify that the current One UI 8.5 rollout focuses on S23 and A-series stability and security, rather than S26-specific hardware features [1].
Samsung is deploying the update across all global markets to ensure a consistent user experience [1], [3]. Users can typically find the update in their device settings under the software update menu.
“Samsung's One UI 8.5 rollout is now reaching Galaxy S23 and A-series phones globally.”
This rollout demonstrates Samsung's strategy to maintain a competitive edge in software support, which is increasingly a key selling point for consumers. By addressing battery and overheating issues reported in previous patches while expanding security to older models like the S23, Samsung is attempting to reduce churn toward competitors who offer long-term software guarantees.
