The Samsung Galaxy S25+ is one of the most anticipated Android smartphones of its generation, boasting cutting-edge hardware, a sleek design, and enhanced performance. While most users will enjoy the out-of-the-box One UI experience based on Android, privacy-conscious individuals may want more control over their devices. This is where GrapheneOS comes into play. Known for its security-focused approach, GrapheneOS is a custom operating system that is gaining popularity among tech enthusiasts. But how compatible is GrapheneOS with the Galaxy S25+, and can you install it? Let’s dive into the details.
What is GrapheneOS?
GrapheneOS is an open-source privacy and security-focused mobile operating system based on the Android Open Source Project (AOSP). Initially designed for Pixel devices, GrapheneOS removes proprietary Google components, enhancing both transparency and security.
- Privacy-by-default: GrapheneOS comes without pre-installed Google services or tracking mechanisms.
- Hardened security: It introduces a range of memory safety and exploit mitigation techniques.
- Minimalist UI: You get a clean, clutter-free interface optimized for privacy.
Galaxy S25+ Compatibility with GrapheneOS
Here’s the catch — GrapheneOS is officially supported only on Google Pixel devices. This limitation is primarily due to the OS relying on the unique Titan M security chip and Pixel Verified Boot process. The Galaxy S25+, while a powerhouse of hardware and features, does not share the same security architecture. As a result, GrapheneOS is not officially compatible with the Galaxy S25+.
However, that hasn’t stopped the developer community from attempting workarounds. The Galaxy S25+ has unlocked bootloader options and powerful ARM-based internals, which make it a tempting candidate for custom ROM development.

Alternative Solutions for Privacy Enthusiasts
If running GrapheneOS directly on the Galaxy S25+ is out of reach, there are other custom ROMs focused on privacy and de-Googling that may be compatible with your device. Examples include:
- LineageOS: A popular custom ROM that provides a near-stock Android experience with regular updates and the ability to exclude Google services.
- CalyxOS: While still Pixel-focused, it may gain broader device support in future updates.
- DivestOS: Based on LineageOS, this OS is engineered for security and privacy with a deeply de-Googled approach.
Installing these alternatives on your Galaxy S25+ can provide some of the benefits of GrapheneOS, although full hardware compatibility and the highest levels of security may not be guaranteed.
Steps to Explore Custom OS on Galaxy S25+
If you’re set on installing a custom OS for better privacy, here’s a general outline of what the process would look like:
- Unlock the bootloader: This will void your warranty and erase all data, so back up everything first.
- Install a custom recovery like TWRP: This tool allows you to flash alternative operating systems onto the device.
- Select and download your ROM: Choose one that has compatible builds for your device model.
- Flash the ROM: Use the recovery to install the ROM and optionally, additional ZIP files for microG or other features.
- Test and tweak: Ensure everything is working correctly, including Wi-Fi, camera, and cellular data.

Cautions and Considerations
Before venturing into the world of custom ROMs, it’s important to understand the risks:
- Warranty void: Unlocking the bootloader often voids the manufacturer’s warranty.
- Bricking risk: Installing software incorrectly can render the device unusable.
- Loss of features: Samsung’s proprietary features, like Knox security or certain camera modes, may not work on custom ROMs.
Additionally, even though a ROM might appear to be secure, it’s vital to verify its authenticity and read feedback from other users to avoid malicious software.
The Future of GrapheneOS on Non-Pixel Devices
There is ongoing interest in porting GrapheneOS or creating similar AOSP-based operating systems for a broader range of smartphones, including Samsung’s. However, until GrapheneOS expands its support infrastructure or community forks become widespread and reliable, installing it on a Galaxy S25+ remains impractical for most users.
For those who prioritize absolute privacy and security, purchasing a compatible Pixel phone remains the best route. However, with the Galaxy S25+’s hardware capabilities, it’s likely that custom ROMs tailored for privacy will increasingly integrate with this popular device.
Stay tuned to developer communities like XDA Developers and Reddit’s r/privacy to follow emerging solutions and new builds tailored for high-end Android devices like the Galaxy S25+.
Conclusion: While full GrapheneOS compatibility for the Galaxy S25+ isn’t currently available, those determined to enhance privacy can find solace in other trustworthy, privacy-first ROMs. Just make sure to proceed with caution and stay informed through trusted sources.
