After Google took the lead in launching mobile phone security updates for many years, Samsung has been the company that launched Crescent Android updates in recent months. The September 2021 security update is no exception, and Samsung has already upgraded these Galaxy devices.

The rollout of the September 2021 update for Galaxy devices began on August 30, exactly one week before the first Monday of the month when Google usually releases a list of core security issues in patches. However, this month, due to the US Labor Day being held on Monday, September 6, things were further postponed.

However, in Samsung's specific aspects, for some devices, the September 2021 update may bring two significant changes. First of all, earlier this year, Google promised to fix the issue between Galaxy devices and Android Auto in the July security patch. However, this ultimately failed, and the fix will not arrive until the September "maintenance" release. Now that the update is more widely available, we are actively investigating whether the Android Auto issue has been fixed.

At the same time, some devices including Galaxy S20 FE and Galaxy Z Fold will be upgraded to One UI with the September 2021 update. The upgraded phones get the (admittedly limited) benefits of One UI 3.1.1, including adjustments to the phone app and new sleep mode switching in quick settings, although some improvements may be device-specific.

According to Samsung’s official patch notes, Google’s Android security bulletin includes 3 critical fixes, 29 high severity fixes, and 14 medium fixes. Most importantly, Samsung itself closed 23 security vulnerabilities in the September 2021 update.

So for which devices does Samsung roll out the September 2021 update? Even before the start of September, Samsung launched five different phones to receive updates, and paid special attention to the company's foldable phones. In the next few weeks, more phones will be steadily updated.

This list will contain instructions on where the update was first released and whether it is also available in the United States. As usual, the newly added content will be marked in bold.

For more than a decade, the S series has been Samsung's flagship product line, providing the best mainstream Android phone experience, albeit at a high cost. For an extra premium, the Galaxy S series is usually the first to receive monthly security updates, giving or accepting any complications from individual phone operators. This time, Galaxy S20 FE and S20 FE 5G (Samsung’s affordable flagship products launched in 2020) were the first to receive updates on August 30.

Next comes the update. Galaxy S10 Lite owners started to discover the September 2021 security patch update before September 3rd. The first reports came from Spain.

At the same time, the Galaxy S20 trio-including the basic, Plus, and Ultra models-received a relatively small September update within a few days of the dedicated One UI 3.1.1 upgrade, which enhanced application opening Speed, camera speed and other functions. As of September 9, the Galaxy S20 series unlocked models began to receive updates in the United States, and on the 17th, carrier models also followed up.

Surprisingly, the newer Galaxy S21 series lags behind in this update, and European device owners saw the update on September 6, a full week after the Galaxy S20 FE was released. Next came the Galaxy S10 series trio. The S10, S10+ and S10e received the update on the same day-and later arrived on the US device locked by the carrier on September 23.

Depending on how you look at it, people may argue that the Galaxy Z series foldable phones are Samsung's true "flagship" phones today. This is especially true now, because the price of the Galaxy Z Flip 3 is already less than $1,000, which makes foldable devices more attractive to ordinary consumers. At the same time, the larger Galaxy Z Fold 3 continues to push the limits of smartphones.

Before the start of the new month, on August 31, both Galaxy Z Flip and Z Flip 5G received the One UI 3.1.1 update, which mainly improved the experience of foldable devices, including Flex mode panel and support for drag and drop With the same update, these phones have been upgraded to the September 2021 security patch. The update did not launch the Z Flip model in the United States until September 24, starting with the mobile phone locked by the operator.

On September 6, the original Galaxy Fold received the same treatment as the security patch and One UI update.

At the same time, the Galaxy Z Fold 3 and Z Flip 3 have only been in the hands of customers for a few days, and Samsung has already launched the September 2021 update for these two phones. Since Galaxy Z Flip 3 and Z Fold 3 are both One UI 3.1.1 out of the box, apart from security improvements, this update is likely not to change much. These updates did not begin to arrive in the United States until the carrier update for Z Flip 3 on September 27, followed by the carrier and unlock update for Z Fold 3 on September 29.

Samsung’s second-generation foldable phone, Galaxy Z Fold 2, was updated on September 14 from the US model locked by the carrier, breaking the usual sequence of first updates for international models. The international version of this update is more than a week later than September 23.

As of the latest Galaxy Unpacked event, the Galaxy Note series seems to be completed and has been replaced by Samsung's Galaxy Z Fold series in the 2021 hardware lineup. Z Fold 3 even supports the iconic S Pen of the Note series, although it is not so easy to collect. In other words, due to issues such as continued chip shortages, this may only be a decision for 2021.

Currently, only a few Galaxy Note devices have received the September 2021 update, starting with the Note 20 series duo. On September 5th, Brazil's Galaxy Note 20 and Galaxy Note 20 Ultra users began to see the September 2021 security patch, just a few days after the more important One UI 3.1.1 update was launched. More than a week later, the same update also applies to US carriers locked phones.

As the most recent Note lineup, Samsung released the 2019 Galaxy Note 10 and 10+ updates in South Korea on September 7, and the 2020 Note 10 Lite update will be released a few hours later. Until September 23, after unlocking the Note 10 phone, the United States did not see any of these updates for several weeks.

As you might expect, the price of the Galaxy Tab series is usually lower than most flagship Samsung phones, and it stores less private data than daily driving smartphones, but the update speed is slower than other Androids. In other words, Samsung has made some of the only Android tablets worth owning, and the fact that Galaxy Tabs often receive updates further promotes this fact.

So far, only the Galaxy Tab S7 series has received the September security update, and European device owners will see the update on September 17. With this update, Galaxy Tab S7 now has the features of One UI 3.1.1 that debuted for the first time, including "Lab" to force applications to support multi-window mode and other functions.

In addition to Samsung's continued strength in the flagship and foldable divisions, the company also dominates the field of affordable Android phones between its A, M and F series. This is supported by Samsung's willingness to update monthly and even their mid-range A-series phones, although as long as their flagship products get the same treatment. Even if the monthly updates run out, Samsung will follow up, update once a quarter, and then update once every six months.

Starting from the update wave, Galaxy A8 (2018) received the update on September 4. It is worth noting that the update was carried out after the June and August updates of the phone, although the Galaxy A8 (2018) is only planned for non-enterprise customers.

On September 6, Samsung also launched a side-by-side update of the Galaxy A52 and Galaxy A72. These two phones are also the company's two most popular and affordable phones, and they are also launched side-by-side. Galaxy A52s 5G lags behind by a few days and received updates in many European countries/regions on September 9.

At the same time, Galaxy A21s was not updated until September 13, while Galaxy A10s was a few days later than September 17. At the same time, both Galaxy A30s and A50 received their respective updates on September 22, while the 5G version of Galaxy A51 received updates on September 23.

Continue to update quickly in batches. Galaxy A52 5G, Galaxy A32, Galaxy A11 and Galaxy A12 all received updates on the same day on September 24. The non-5G Galaxy A51 was released a few days after sunset on September 27, and was subsequently released by the Galaxy A71 5G on the 28th.

As for the low-end M series, the Galaxy M21 was the first to be upgraded on September 7. India and Sri Lanka have confirmed the upgrade. The current guess is that the update is more important than a simple security patch, although it has not been confirmed.

Next is the Galaxy M31, which installed patches for devices in India on September 9. It is worth noting that through this update, M31 has received support for Samsung Pay Mini, which is a mobile payment option based on the use of QR codes. The Galaxy M51 update is more straightforward and was released on September 22.

Galaxy M30s currently only receive quarterly updates instead of monthly updates. This means that when its update arrived on September 28, it went from the June 2021 patch to September 2021.

The Galaxy F series, if you are not familiar with it, are usually renamed Galaxy M devices, but they are sold exclusively in India through Flipkart. The first Galaxy F series phone to receive the September update is the Galaxy F41 on September 15.
