Galaxy S23 gets June update in the US, May patch in Europe

Yesterday, Samsung released the June security patch for the Galaxy S24 series in the US and South Korea. The same update is now available for the Galaxy S23 series. The update is currently rolling out to the carrier-locked units in the US but should go global soon. The European Galaxy S23 Ultra, meanwhile, is picking up the new firmware build with the May security patch.

The new Galaxy S23 update doesn’t bring the June security patch everywhere

Last month, Samsung rolled out two updates to the Galaxy S24 Ultra and Galaxy S23 Ultra in some markets. The first update was a regular May security patch while the second brought fixes for a video rattling issue and battery optimizations. The company didn’t push the second build globally. We expected it to bundle those fixes with the June patch in other markets.

The June update for the Galaxy S24 series did come with the same build version as the second May release. However, the US models don’t seem to have picked up anything more than the latest security patch. The Korean models, meanwhile, received additional fixes. It is unclear why Samsung didn’t push the same changes globally. Perhaps the issues don’t exist in the US units.

Now, Samsung is rolling out the June security update to the Galaxy S23 series in the US, and—you guessed it right—it’s the same build version. The new update is available for carrier-locked units with the build number S91*USQS3CXE3. The official changelog confirms that the update is all about this month’s security fixes. There aren’t any additional changes in tow.

Surprisingly, the Galaxy S23 Ultra is picking up this firmware build (S918BXXU5CXE3) with the May security patch. It is essentially the second May update we discussed above. Since the June SMR (Security Maintenance Release) is already available, it’s unclear why Samsung didn’t bundle it. The device should pick up another update with the June patch in the coming days.

This month’s security patch for Galaxy devices addresses 59 vulnerabilities

Samsung’s June SMR for Galaxy devices contains fixes for 59 security issues. These include 37 Android OS vulnerabilities and 22 Galaxy-specific security flaws. At least one of these is confirmed to be a critical flaw. The Korean firm will soon push the new SMR to more eligible Galaxy models, including foldables.
