Xiaomi has initiated the release of the August 2026 Android security patch for a limited set of devices running ChinaOS. The update is confirmed for the Xiaomi Pad 7 Ultra and Xiaomi Pad 7S Pro 12.5, with builds ChinaOS 3.0.303.0.WODCNXM and ChinaOS 3.0.304.0.WOTCNXM respectively. Both updates started rolling out on August 1.
Current Coverage and Patch Status
According to the official Android security bulletin site, the August 2026 security details are not yet published. Consequently, no comprehensive list of Xiaomi, REDMI, or POCO devices receiving this month’s patch has appeared in global trackers. The android source page for the August 2026 bulletin (source.android.com) remains without the specific security fixes information.
The only confirmed updates so far target ChinaOS builds for three Xiaomi models:
- Xiaomi 15S Pro – Build OS3.0.303.0.WODCNXM
- Xiaomi Pad 7 Ultra — Build 3.0.302.0.WOXCNXM
- Xiaomi Pad 7S Pro 12.5 — Build 3.0.304.0.WOTCNXM
Users in China checking update availability can verify these builds through Xiaomi’s standard update channels.
Implications and Availability
The rollout shows that Xiaomi is prioritizing its tablet lineup in China for this monthly security update cycle. No evidence of other Xiaomi, REDMI, or POCO models receiving the patch yet is available. The absence of official security bulletin details means the scope and nature of the fixes remain unclear.
Owners of the Xiaomi Pad 7 Ultra and Pad 7S Pro 12.5 in China may receive the update ahead of other devices or global markets. It is not yet known when or if the update will reach international versions or other Xiaomi product lines.
For users tracking update eligibility and availability, the MemeOS Enhancer app allows checking for the latest HyperOS builds and security patch status by device and region.
This marks the first known rollout of the August 2026 Android security patch for Xiaomi. Earlier security patch tracking at MemeOSUpdates Security Patch Tracker showed no device coverage for this month until these builds appeared. It establishes a reference point for future rollouts. The firmware packages for these updates can be found at Xiaomi firmware repositories tracked on MemeOSUpdates.com, where users can download official Xiaomi firmware by device and region
