Samsung Stops Software Updates for Galaxy S21 Series
February 09, 2026 ・0 comments
Understanding the Software Lifecycle Policy in the Malaysian Market
When the Galaxy S21 series first launched in Malaysia, it was positioned as a pinnacle of mobile engineering, with prices starting from approximately RM3,499 and reaching well over RM5,000 for the Ultra variant. At that time, Samsung's commitment to software longevity was a primary selling point for those purchasing through telco bundles like Maxis Postpaid or CelcomDigi plans. However, the standard industry practice dictates a finite window for support. The cessation of major updates means these devices will likely remain on their current version of One UI, missing out on future innovations in generative AI and system-level optimisations.
For the Malaysian user, this is more than just a lack of new features. Our digital ecosystem is heavily reliant on secure mobile environments. With the end of consistent software support, the gap between emerging cyber threats and the device's ability to defend itself begins to widen. While the hardware remains capable, the underlying software architecture will eventually become a legacy system, making it harder for the devices to interface seamlessly with new government and financial applications.
The Critical Risk to Mobile Banking and Security
Malaysia has seen a rapid shift toward mandatory mobile-based authentication. Major financial institutions such as Maybank, CIMB, and Public Bank have migrated from SMS TAC to secure in-app verification like Secure2u. These applications often require a minimum security patch level to function correctly. As the Galaxy S21 series enters its sunset phase, there is a looming deadline where banking apps may eventually flag these devices as "unsecured" or "outdated."
Data Privacy and the Tropical Heat Factor
Beyond software, the physical longevity of the S21 series in Malaysia's tropical climate is worth noting. High humidity and ambient temperatures often accelerate the degradation of internal components, particularly the lithium-ion batteries and the adhesive used in the "Glastic" or glass backs. An unsupported phone that runs hotter due to unoptimised legacy software is more prone to battery swelling or the infamous "green line" display issues that have been reported across various OLED panels in the region. Without official software fixes to manage thermal throttling or power efficiency, these hardware risks become more pronounced.
Impact on Resale Value at Local Trade-in Centres
The second-hand market in Malaysia, facilitated by platforms like Carousell and physical kiosks in Low Yat Plaza or Digital Mall, is highly sensitive to software status. A device that is no longer supported by the manufacturer sees an immediate and sharp decline in trade-in value. Malaysian users who intended to use their S21 Ultra as a high-value trade-in for the upcoming S25 series may find that authorised resellers like CompAsia or InstaCash offer significantly lower rates now that the support window has closed. Acting sooner rather than later is often the best financial strategy for those looking to recoup costs.
The Evolution of Samsung's Update Promise
It is important to recognise that the S21 series was the catalyst for Samsung's improved update policy. Following the launch of these devices, Samsung extended its commitment to four generations of One UI and five years of security updates for newer models. Ironically, while the S21 series paved the way for this high-authority standard, it is also the first to reach the end of the older, shorter cycle. This creates a clear divide between the "legacy" era and the "modern" era of Samsung longevity.
To ensure your personal data remains protected, Malaysian users should immediately back up their Galaxy S21 data to a cloud service like Google Drive or OneDrive. If you plan to continue using the device, avoid sideloading APKs and stick strictly to the Google Play Store to mitigate risks associated with the lack of new security patches.
Strategic Options for Galaxy S21 Owners in Malaysia
If you are currently holding a device from the S21 range, you essentially have three strategic paths. Each path depends on your budget and how much you rely on your smartphone for daily productivity and financial transactions in the Klang Valley's fast-paced environment.
Option 1: The Transition to the Galaxy S24 Series
Upgrading to the current flagship is the most logical step for those who want to stay within the Samsung ecosystem. The Galaxy S24 series offers the Galaxy AI suite, which is particularly useful for local professionals who need live translation or advanced photo editing. Furthermore, the S24 series comes with a staggering seven-year software support promise, ensuring that an investment made today will remain relevant until 2031.
Option 2: Repurposing the Device
If the hardware is still in pristine condition, the S21 series remains a powerful tool. In a Malaysian household, an S21 can be repurposed as a dedicated media controller for smart home setups (Unifi TV or Google Home), a high-quality webcam for remote work, or a secondary device for navigation using Waze or Google Maps to save your primary phone's battery from the intense Malaysian sun.
Option 3: Professional Refurbishment and Battery Replacement
For those determined to keep the device for another year, visiting an authorised Samsung Service Centre in Mid Valley or Suria KLCC for a genuine battery replacement is advised. While this won't solve the software support issue, it will ensure the hardware remains stable while you wait for seasonal sales like 11.11 or 12.12 to grab a new model at a discount.
Verdict: A Necessary Step Forward
While the news of ending support may be frustrating for loyal fans, it is a necessary part of the technological cycle. The Galaxy S21 series has served as a workhorse for many Malaysians, surviving the pandemic era and the transition to 5G via Digital Nasional Berhad (DNB). However, as mobile threats evolve and Malaysian digital infrastructure becomes more complex, moving to a supported platform is no longer just a luxury—it is a security requirement. Owners should begin planning their exit strategy to ensure their digital life remains uninterrupted and secure.
Frequently Asked Questions
Will my Galaxy S21 stop working immediately?
No, the phone will continue to function normally. You can still make calls, use apps, and take photos. However, you will no longer receive new Android features, and eventually, some apps may stop supporting your older version of the operating system.
Can I still use Maybank MAE or other banking apps on the S21?
For now, yes. Most Malaysian banking apps support several versions of Android. However, within the next 12 to 24 months, as security requirements increase, these apps may require a newer security patch that the S21 series will no longer have, eventually rendering them incompatible.
Is it worth buying a second-hand S21 Ultra in Malaysia now?
Unless you are using it for non-sensitive tasks or as a backup camera, it is generally not recommended for use as a primary device. The lack of future security updates makes it a risky choice for personal data management in 2024 and beyond.
Where is the best place to trade in my old Samsung in Malaysia?
You can trade in your device at any Samsung Experience Store, or use reputable third-party platforms like CompAsia, InstaCash, or even retail chains like Senheng and Harvey Norman, which often offer promotional top-ups for trade-ins during new flagship launches.
