Devices Compatible with Nougat Rev4
Nougat Rev4 was commonly associated with the Samsung Galaxy S7 and S7 Edge, two flagship devices of their time. These devices received Nougat updates with various revisions to address hardware-specific performance and software issues.
However, compatibility with Nougat Rev4 largely depends on the bootloader revision of your device. The bootloader acts as a gateway to the operating system, and its version determines whether updates or modifications (such as rooting) can be applied.
How to Check Your Device’s Revision:
- Go to Settings > About Phone.
- Check the Android version and software details.
- Look for the bootloader revision, often listed as something like Rev4, Rev10/A, or Rev11/B.
Rooting and Customization with Nougat Rev4
For tech enthusiasts, rooting a device running Nougat Rev4 opens up a world of possibilities. Rooting gives users administrative access to their device, enabling them to customize it, remove pre-installed apps, and install custom ROMs.
Rooting Methods for Nougat Rev4:
Devices with bootloader versions Rev4 to Rev10/A can be rooted using tools like:
- Odin flashable firmware: A popular tool for Samsung devices that allows users to install custom or stock firmware.
- ADB-based methods: A command-line tool used for advanced rooting procedures.
For devices with bootloader version Rev11/B, rooting requires the use of combination firmware, which provides limited root access.
Benefits of Rooting Nougat Rev4:
- Customization: Install custom ROMs to change the look and feel of your device.
- Enhanced Performance: Remove bloatware and optimize the system for better speed and battery life.
- New Features: Access advanced features and tools unavailable on stock firmware.
Risks of Rooting:
- Void Warranty: Rooting often voids the manufacturer’s warranty.
- Security Vulnerabilities: Rooted devices are more exposed to malware and hacking attempts.
- Potential Bricking: Incorrect rooting methods can render your device unusable.
Importance of Software Updates
While Nougat Rev4 was an excellent update for its time, it’s important to recognize the limitations of older software:
Improved Security:
- Modern Android versions offer stronger security measures to combat evolving cyber threats.
- Apps on older Android versions may become vulnerable to malware.
Access to New Features:
- Features like gesture navigation, enhanced privacy controls, and better performance optimization are only available in newer Android updates.
Avoiding Obsolescence:
- Over time, app developers stop supporting older Android versions like Nougat. This can lead to compatibility issues and a lack of updates for key apps.
For devices no longer receiving official updates, installing a custom ROM based on newer Android versions is a great alternative.

Conclusion
Nougat Rev4 represents a significant step in the evolution of Android Nougat, offering a stable and secure experience for its time. For tech enthusiasts, it provided opportunities for customization and experimentation through rooting. However, given its age, Nougat Rev4 lacks modern security features and app compatibility, making it less practical for everyday use in 2024.
If you still use a device running Nougat Rev4, consider upgrading to a newer version or exploring custom ROMs for a safer, more feature-rich experience. Always weigh the benefits and risks carefully, especially when considering rooting or other modifications.
