Source: Android Authority
TL;DR

- The Galaxy S26 series moves to build AZDG, while the Galaxy S25 lineup jumps to BZCL.
Samsung releases a second April security update
Samsung normally delivers one security patch per month, but as April 2026 draws to a close, a surprise second April patch is rolling out to the company’s flagship phones. The first April updates for the Galaxy S26 and S25 series were already released earlier in the month (Android Authority). The follow‑up update was first spotted by Droid Life (source), suggesting a last‑minute security issue or critical fix that couldn’t wait until May.
Verizon’s changelog is brief, stating the updates provide “the most up‑to‑date Android security patches for your device” (link). However, the new build numbers show these are new versions that have not appeared in update trackers before.
Affected devices and build numbers
- Galaxy S26 series (standard, Plus, Ultra) → Build AZDG
- Galaxy S25 series (including S25 Edge) → Build BZCL
- Galaxy Z Fold 5 and Galaxy Z Flip 5 → receiving their first April security update
These devices are the ones receiving the second April patch for the S‑series and the first April patch for the Z‑series.
