Official Software Support: A Look Back and Current Status

Understanding where your Samsung Galaxy A90 5G or Galaxy A70s stands today requires a brief look at its update history. Samsung, like most Android manufacturers, provides a defined period of software and security support for its devices. For these older A-series models, that period has passed.

Samsung Galaxy A90 5G: Official Update History

The Samsung Galaxy A90 5G was a notable device when it launched, featuring a powerful Snapdragon 855 processor and bringing 5G connectivity to the A-series. It originally shipped with Android 9 Pie and received two major Android operating system updates: Android 10 and Android 11. It also received One UI 2.0 and later One UI 3.1. Official security patches typically continued for a period after the last major OS update, but this support officially ended some time ago. There was never an official Android 12 or One UI 4 update for the Galaxy A90 5G.

Samsung Galaxy A70s: Official Update History

Similarly, the Samsung Galaxy A70s, powered by the Snapdragon 675, launched with Android 9 Pie. It also received two major Android updates, bringing it to Android 10 and then Android 11. It received corresponding One UI updates, likely up to One UI 3.1. Like its A90 5G sibling, official security support has concluded. Any discussions about an official Android 11 update for the Galaxy A70s are now historical, as the device has moved beyond official support.

What ‘End-of-Life’ Means for Your Device in 2025

When a phone reaches “end-of-life” (EOL) for software support, it means the manufacturer, in this case, Samsung, will no longer provide:

New versions of Android (e.g., Android 12, Android 13, Android 14, Android 15).
Updates to the One UI interface.
Critical security patches to address newly discovered vulnerabilities.
Bug fixes specific to the operating system or Samsung’s software.

In 2025, both the Galaxy A90 5G and A70s are firmly in this EOL category. While the phones will continue to function, the lack of ongoing security updates is the most significant concern for users.

The Risks of Using an Unsupported Phone in 2025

Continuing to use a Samsung Galaxy A90 5G or Galaxy A70s without official software and security updates in 2025 isn’t necessarily a deal-breaker for everyone, but it’s crucial to understand the risks involved. These aren’t just theoretical; they can have real-world implications for your data and device performance.

Security Vulnerabilities and Patch Gaps

The biggest concern with an unsupported Android phone is security. Cybercriminals are constantly finding new ways to exploit weaknesses in operating systems and applications. When Samsung no longer releases security patches for your device, any newly discovered vulnerabilities remain unaddressed. This creates “patch gaps” that malicious actors can target. Your personal data, banking information, and online accounts could be at higher risk if your device is compromised. While Google Play Services still receives updates independently of your OS, it can’t cover all potential system-level exploits.

App Compatibility and Performance Degradation

As Android evolves, so do the requirements of many applications. Newer apps or updates to existing apps might eventually stop supporting older Android versions that your Galaxy A90 5G (stuck on Android 11) or Galaxy A70s (also on Android 11) runs. You might find certain features unavailable, or the apps simply won’t install or run correctly.

Beyond compatibility, the hardware itself, while once powerful (Snapdragon 855 for the A90 5G, Snapdragon 675 for the A70s), might struggle with the demands of modern, resource-intensive applications, leading to performance issues like slower loading times or occasional freezes. In 2025, the Snapdragon 855, while still capable for basic tasks, will show its age with demanding games or complex multitasking, falling significantly behind current mid-range chips. The Snapdragon 675 will similarly be quite limited, likely struggling with anything beyond light social media and web browsing.

Battery Health and Hardware Longevity

While not directly tied to software updates, the age of your device means its internal components are also aging. Battery health is a prime example; over time, batteries degrade, holding less charge and potentially affecting overall performance. Other hardware components can also experience wear and tear. While you can replace a battery, general hardware longevity is a factor to consider when evaluating the long-term usability of an unsupported phone.

Breathing New Life: Exploring Custom ROMs for Your Galaxy A90 5G & A70s

For those with a bit of technical comfort and a desire to extend their phone’s life far beyond official support, custom ROMs are a compelling option. They allow you to replace Samsung’s One UI with a community-developed version of Android, often bringing much newer versions and additional features.

What Are Custom ROMs and Why Consider Them?

A custom ROM is essentially an aftermarket firmware based on the Android open-source project (AOSP). Instead of using the software provided by Samsung, you install a version of Android developed by independent developers. This can be a fantastic way to upgrade your Galaxy A90 5G or Galaxy A70s to a newer Android version, like Android 13, Android 14, or even Android 15, which your phone would never officially receive. People consider them for several reasons:

Newer Android Versions: Access features and security improvements from recent Android releases.
Extended Security: Many custom ROMs include the latest Android security patches.
Improved Performance: Often, custom ROMs are lighter than stock manufacturer firmware, potentially leading to better performance and battery life.
Customization: They frequently offer more customization options than stock Android.
No Bloatware: Typically, custom ROMs are free of pre-installed apps you might not want.

Benefits: Newer Android Versions and Enhanced Features

Imagine your Galaxy A90 5G running Android 14, or your Galaxy A70s experiencing Android 13. With custom ROMs, this is entirely possible. You’d gain access to modern privacy controls, updated notification systems, enhanced battery management features, and the overall aesthetic and functional improvements of a contemporary Android experience. Many custom ROMs also include additional features like advanced theming, gesture controls, and performance tweaks not found in stock software.

Potential Risks and Considerations

While exciting, installing custom ROMs isn’t without its caveats. It requires a certain level of technical expertise and carries risks:

Voiding Warranty: Although your phones are out of warranty anyway, it’s a common risk with custom ROMs.
Bricking Your Device: An incorrect installation can render your phone unusable.
Security Concerns: You are relying on community developers. While reputable ROMs are generally safe, always source from trusted platforms like XDA Developers.
Stability Issues: Some ROMs might have bugs or stability issues, especially in early development stages. Not all hardware features (like specific camera modes or sensors) might work perfectly.
SafetyNet/Google Play Services: Some apps (especially banking or streaming apps) might detect a modified device and refuse to work. There are workarounds, but they add complexity.

Finding Custom ROMs for Galaxy A90 5G

For the Galaxy A90 5G, given its Snapdragon 855 processor, you’ll likely find a good selection of custom ROMs. The XDA Developers forum is the primary hub for this. You might find projects like Evolution X or LineageOS builds that aim to bring newer Android versions, such as Android 13 or Android 14, to the device. Always look for active development threads and read user reviews carefully.

Finding Custom ROMs for Galaxy A70s

The Galaxy A70s, with its Snapdragon 675, also has a presence in the custom ROM community. Again, XDA Developers will be your best resource. You might find stable versions of LineageOS or Pixel Experience, which provide a clean, stock Android feel, often based on Android 12 or Android 13. Ensure the ROM you choose is specifically for your A70s model variant.

A Practical Roadmap to Custom ROM Installation

Installing a custom ROM is a multi-step process that requires careful attention to detail. This is a general roadmap, but **it is crucial to find and follow device-specific guides** for your exact phone model (e.g., SM-A908B for A90 5G) on reputable forums like XDA Developers.

Thorough Research: Before anything else, identify your exact device model number (e.g., SM-A908B, SM-A707F). Search XDA Developers forums specifically for custom ROMs compatible with your model. Read the entire guide, including prerequisites, known bugs, and user feedback.
Backup Everything: This step is non-negotiable. Back up all your personal data (photos, contacts, apps, messages) to a cloud service or computer. The installation process will wipe your device.
Unlock the Bootloader: This is a critical, device-specific step that allows flashing custom software. It typically involves enabling “OEM Unlocking” in Developer Options and using fastboot commands on a computer. **Unlocking the bootloader will factory reset your device.**
Install Device Drivers: On your computer, ensure you have the correct Samsung USB drivers and ADB/Fastboot drivers installed. These are essential for your computer to communicate with your phone during the process.
Flash a Custom Recovery: Tools like TWRP (Team Win Recovery Project) are custom recovery environments that allow you to flash ROMs, create full system backups, and perform maintenance. You’ll typically flash TWRP via fastboot.
Download the ROM and GApps: Download the custom ROM file (.zip) and, if the ROM doesn’t include them, a compatible Google Apps (GApps) package (.zip) for your Android version and CPU architecture (ARM64).
Transfer Files: Move the downloaded ROM and GApps files to your phone’s internal storage or an SD card.
Boot into Custom Recovery: Restart your phone and boot into TWRP recovery mode (usually by holding specific button combinations).
Perform Wipes: In TWRP, perform a “Factory Reset” (which typically wipes data, cache, and Dalvik cache). Some guides might recommend additional wipes (e.g., “system” partition), so follow your specific ROM’s instructions.
Flash the Custom ROM: Select the ROM .zip file in TWRP and flash it.
Flash GApps (if needed): Immediately after flashing the ROM, flash the GApps .zip file.
Reboot System: Once flashing is complete, reboot your device. The first boot can take a long time.

Caveat: This roadmap is a highly simplified overview. Each device and ROM combination will have specific instructions and potential pitfalls. If you’re unsure at any point, **stop and seek assistance from experienced users on forums like XDA Developers** before proceeding. Proceeding without full understanding can lead to irreversible damage to your device.
