Overview
- Samsung is rolling a duplicate April 2026 package to the Galaxy S26 and S25 lines plus the Z Fold 5 and Z Flip 5 in the U.S., covering nine phones in total.
- Carrier notes list only the April Android security patch, with Verizon saying the builds provide the most up to date security patches for these devices.
- Observed build IDs include S948USQS2AZDG for the Galaxy S26 Ultra and F731USQS7FZC5 for the Galaxy Z Flip 5, signaling new firmware beyond the earlier April release.
- The April 2026 bulletin addresses 47 vulnerabilities, with 33 fixes from Google, 10 from Samsung Mobile, and 4 from Samsung’s Semiconductor unit, including 14 marked high‑priority.
- Distribution remains staged by region and carrier, while the April patch is also reaching the Galaxy A35, A26, A25, A07 5G, and A07 4G in Europe and global markets, so some users will need to wait or check manually in Settings.
