GRAPHENEOS

The origins of GrapheneOS can be traced back to the need for a more secure and private mobile operating system. The project was initially a fork of CopperheadOS, another security-focused Android distribution. However, GrapheneOS quickly distinguished itself by adopting a more rigorous approach to security and privacy. The developers behind GrapheneOS recognized that to achieve true security, every aspect of the operating system needed to be scrutinized and hardened. This philosophy has guided the development of GrapheneOS from its inception, resulting in an operating system that is notably more secure than its predecessors and contemporaries.

One of the critical areas where GrapheneOS excels is in its implementation of sandboxing and exploit mitigations. Sandboxing is a security mechanism that isolates applications from each other and from the core operating system, preventing malicious apps from accessing sensitive data or system resources. GrapheneOS enhances this mechanism by implementing stricter sandboxing policies and additional layers of isolation. This ensures that even if an application is compromised, the damage is contained and does not affect the entire system.

Exploit mitigations are another layer of security that GrapheneOS employs to protect against vulnerabilities. These mitigations include techniques such as Address Space Layout Randomization (ASLR), Control Flow Integrity (CFI), and stack canaries. By implementing these measures, GrapheneOS makes it significantly more difficult for attackers to exploit known or unknown vulnerabilities in the operating system or installed applications

Hardware-based security features are also a cornerstone of GrapheneOS’ security architecture. The operating system takes full advantage of the hardware security modules present in Google Pixel devices, such as the Titan M Security chip. These modules provide a secure environment for storing cryptographic keys and performing sensitive operations, ensuring that even if the main operating system is compromised, the most critical data remains protected

The developer community behind GrapheneOS is another key factor in its success. Comprised of highly skilled and dedicated individuals, this community is committed to maintaining and improving the operating system. They regularly release security updates and patches, often ahead of other Android distributions, to address new vulnerabilities and threats. This proactive approach to security ensures that GrapheneOS users are always protected against the latest risks

Performance is another area where GrapheneOS shines. The operating system is designed to be lightweight and efficient, removing any unnecessary bloatware and optimizing system resources. This results in a fast and responsive user experience, with minimal lag or stuttering. The minimalistic design philosophy of GrapheneOS extends to its user interface, which is clean and intuitive, providing a distraction-free environment for users

Compatibility with the Google Play Store and a wide range of Android applications is a significant advantage of GrapheneOS. Unlike some other custom ROMs, GrapheneOS does not compromise on functionality or convenience. Users can access the full ecosystem of Android apps, ensuring that they do not have to sacrifice their favorite applications for the sake of security and privacy. This compatibility is achieved through meticulous testing and optimization, ensuring that apps run smoothly and securely on GrapheneOS.

Transparency and user control are fundamental principles of GrapheneOS. As an open-source operating system, it allows users to inspect the code and verify that there are no hidden tracking mechanisms or backdoors. This level of transparency is crucial for users who want to ensure that their data is not being misused. GrapheneOS also provides users with fine-grained control over app permissions, allowing them to specify exactly what data and hardware each application can access

The user experience with GrapheneOS is designed to be seamless and intuitive. The installation process is straightforward, and the operating system provides a smooth out-of-the-box experience. This ease of use, combined with its robust security features, makes GrapheneOS accessible to a wide range of users, from privacy enthusiasts to everyday consumers

in comparison to other privacy-focused operating systems like CalyxOS, GrapheneOS offers a more rigorous security approach. While CalyxOS aims to balance privacy and ease of use, GrapheneOS is uncompromising in its focus on security. This makes it the ideal choice for users who prioritize protection over convenience. The operating system’s community, although smaller, is highly technical and focused on deep security and development, ensuring that the OS remains at the cutting edge of mobile security

GrapheneOS’ support for specific hardware is another factor that contributes to its success. By focusing on Google Pixel devices, the developers can ensure precise optimization and compatibility, taking full advantage of the hardware-based security features present in these devices, such as the Titan M Security chips. This strategic choice allows GrapheneOS to deliver a superior security experience compared to operating systems that support a wider range of devices.

The evolution of GrapheneOS from a fork of CopperheadOS to a standalone project has been marked by a series of improvements and refinements. The developers have incorporated the best practices and lessons learned from their predecessors, creating a more secure and efficient operating system. This evolution has allowed GrapheneOS to establish itself as a leader in the field of secure and private mobile operating systems.

In conclusion, GrapheneOS’ success can be attributed to its unwavering commitment to security and privacy, a dedicated developer community, and a user-centric design philosophy. By focusing on advanced security features, minimalistic design, and robust performance, GrapheneOS has set a new standard for mobile operating systems. Its compatibility with the Google Play Store and a wide range of Android applications, combined with its transparency and user control, makes it an attractive option for users who value their privacy and security. With its continued development and improvement, GrapheneOS is poised to remain at the forefront of secure mobile operating systems for years to come.

INSTALLATION

If you follow exactly what is said on GrapheneOS’ website under the installation you will find that it is very easy. It may be a small learning curve but you will get it eventually. What is most important is that you do should have an android phone to do it from as it can bug on the computer. In the browser of the phone it works great.

Follow the guide and you will be fine. https://grapheneos.org/install/web

SETTINGS

Here are some basic rules for being private and secure in GrapheneOS and doing the little extra:
Manager your permissions.
Never should an app have sensor permissions
If there is an app that ask you for contacts then don’t accept if you think it wont need it. For example Signal do not need contacts permission to work, only if you want it to recognise your contacts. This is a personal preference since Signal is a safe app. I do always have as little permissions as possible.

Use a strong password for unlocking. If you require it, you can use biometrics to unlock since it safe on GrapheneOS to do so, only thing to have in mind is that you want to make sure that if you get in trouble and someone want to force you to unlock it, that you restart it.

Restarting Android puts it into a kind of hardened mode and basically it wont let you unlock it unless you got that password, which of course is long and complicated to guess when you made a great password.

I always restart my phone before going through security at the airport.

In the privacy and security settings within GrapheneOS you will find Exploit protection > Auto Reboot > Put a time that wont be annoying but also wont be too long. If your phone get stolen its handy that it will restart and lock itself.

Go back and set your USB-C Port to charge only. This can be changed when you need it.

Turn off Wi-Fi automatically – 30 seconds
Turn off Bluetooth automatically – 30 seconds
This is because your Wi-Fi and Bluetooth is calling out all the time asking for specific SSID and Devices that may or may not be close and on top of that Wi-Fi and Bluetooth protocols can leave you vulnerable to attacks

Hardened memory allocator, just leave them, not many apps really truly need them to run and if you run apps that dont need google play services it is very rare and so I disabled all by default, this is something that give security but you can leave them. It is a lot easier to leave it be but it will give a slight security boost if you disable them.

If you go back you will find “More security and privacy” setting at the bottom of the Security and privacy tab
Notifications on lock screen – Don’t show notifications at all
Show media on lock screen – Off
Allow Sensors permission to apps by default – Off
Save screenshot timestamp to EXIF – Off

Go out to the settings menu and go to Network and Internet > Private DNS > Private DNS provider hostname > go to my.nextdns.io > follow the guide for android

You can make an account on NextDNS if you want to block more things, it is very much customary.

APPLICATIONS

Now you are done and you setup your device, how do you get apps?
Well there are numerous ways of getting apps, my preferred is Aurora store + F-Droid

Aurora is google play for people who care about privacy and F-Droid is open-source

These are fine for normal use. If you want one more within the application “App Store” On GrapheneOS you can install an application call Accrescent and it has some good stuff.
