Several actions may be carried out to enhance privacy and security on Android devices, and they apply to the vast majority of smartphones and tablets using Google’s mobile operating system.
At the same time, in a world of ever-increasing cyber-threats and social media firms eager for user data, there are individuals who require an extra layer of security to ward against both legal and unlawful threats to one’s digital person.
GrapheneOS is an operating system (OS) meant to appeal to such consumers, with a concentration on the study and development of privacy and security technologies.
The free and open-source operating system GrapheneOS was created with privacy and security in mind.
It is built on the Android platform and was created by many of the same individuals that worked for Google to create Android.
Only a few devices, notably the Google Pixel and Pixel XL smartphones, support GrapheneOS.
In this post, we’ll concentrate on the Graphene OS itself, its history, its advantages and disadvantages, the installation manual, and other key details.
So, what is Graphene OS?
Android Open Source (AOSP), or Android in its most “basic” version, is the foundation of GrapheneOS, an open-source operating system created in 2014.
It contains various security features, including encrypted backups, security upgrades that do not require remote access, and limiting Wi-Fi and Bluetooth connections while the smartphone is not in use, all of which are designed to increase privacy and security while surfing on the device.
Additionally, in order to restrict access to user data and information, such as location tracking and activity, the system excludes services like Google Play Store and other Google utility apps.
GrapheneOS-powered mobile devices do not utilize Google Play Services in the same manner as those made by other manufacturers, despite having a very comparable architecture.
The user can run whatever application they choose because the files are installed in APK format, alternate app stores are supported, and the basic functions of Android remain the same.
On Android, GrapheneOS makes it possible to use Google for free. On the bright side, it provides a clean experience because it lacks manufacturer software or carrier utilities.
With the knowledge that your phone won’t be clogged with unnecessary content, you’ll have a foundational set of applications loaded and will be able to download anything you desire.
As a workaround, GrapheneOS functions similarly to MIUI and One UI. Despite this, there are still significant aesthetic and user tracking differences between Graphene and vanilla Android.
The operating system employs methods to reduce whole classes of vulnerabilities and make it considerably harder to attack the most popular sources. For instance, the application sandbox mechanism has been reinforced, which isolates system hacking efforts.
How and why was Graphene OS developed?
Since the middle of the previous decade, GrapheneOS has existed. In 2014, the domain name Grapheneos.org was registered. The XDA Developers forum included a post in 2016 announcing the GrapheneOS project.
However, you may still access the Wayback Machine to access the original announcement post. Daniel Micay, an engineer and researcher with extensive experience in mobile privacy and security, is in charge.
The construction began as a wholly individual endeavor. The Android Open Source Project was the foundation upon which GrapheneOS, formerly known as CopperheadOS, was being developed (AOSP).
The project’s objective was to translate the OpenBSD malloc implementation to Android’s Bionic libc and the PaX kernel updates to the relevant device kernels.
To put it briefly and plainly, it aimed to address a few significant flaws in the Android OS at the time. But as with almost every project, the scale and breadth increased as new, creative solutions to issues, repairs, and enhancements were incorporated.
According to the GrapheneOS website, there were several problems that they categorize as “low-hanging fruit,” or problems that are simple to resolve. Still, they weren’t primarily focused on creating the one and only mobile OS that prioritized security and privacy.
Building something that was actually trying to serve the user, as opposed to the other way around, was the central concept of the entire project.
The developers undoubtedly succeeded in that sense because GrapheneOS is still free and independent a few years later.
The GrapheneOS development firm had some turbulent events at the management level, but the project and the operating system as a whole were not affected and continued to be fully capable of enhancing the security of the basic Android.
GrapheneOS currently accepts donations, has a few competent engineers working full and part-time, and partners that work together on the project. When it comes to privacy and security, you definitely want to hear that they aren’t affected by investors or other third parties.
Features
Protecting consumers against so-called zero-day vulnerabilities is GrapheneOS’s main priority.
Attack surface reduction, or the elimination of unneeded OS code, including typically built-in programs and potentially dangerous features, is what GrapheneOS views as the first line of defense in this endeavor (more on this later).
Toggling Network and Sensors permissions are something that GrapheneOS offers that is not often found on AOSP ROMs.
Additionally, the OS features per-connection MAC randomization, a feature that prevents sensitive metadata from being included in screenshots, and an LTE-only mode that lowers the attack surface of cellular radio by eliminating older code (2G, 3G) and cutting-edge code (5G).
Additionally, if a device is not connected, Wi-Fi and Bluetooth can both be configured to automatically switch off.
By making a vulnerability difficult to build, the ROM also seeks to stop attackers from taking advantage of a flaw.
According to GrapheneOS, significant efforts are devoted to the creation of memory-safe languages and libraries, static and dynamic analysis tools, and more.
Additionally, GrapheneOS has Private Camera, a camera program that can be downloaded from the Google Play Store.
It was developed by the GrapheneOS team (not using AOSP code) and covers the majority of conventional shooting modes in addition to a host of privacy and security features.
It may operate without Network and Media/Storage permissions, scan QR codes alone, and optionally remove EXIF metadata from images and videos.
Another typical attack vector has been blocked by the GrapheneOS team’s creation of a sandboxed, protected PDF reader application.
The Auditor app was created to offer hardware-based authentication of the reliability of the firmware and software on devices.
Last but not least, GrapheneOS developers firmly believe in sandboxing at several levels, via fortification of the kernel and other fundamental OS components.
This entails sandboxing within a particular Android codec, program, or user profile.
The GrapheneOS website has additional information about each of these capabilities, and this list is not all-inclusive.
Advantages
- It is designed for privacy and security. Because it is privately held, GrapheneOS is not affected by large businesses or other trends that can put the interests of the user at risk in the name of profit, convenience, etc. Although Google (the original developers of Android) isn’t the worst company in that sense, there are still some murky areas in the way that user data is handled and bugs are fixed.
- All of the applications’ default permissions are quite limiting. Any app you download won’t be able to access your data without your permission. No extra or pointless risks.
- Being based on AOSP, the OS is incredibly streamlined. No bloatware or other extraneous features that hackers could use against you. The versions of Android that you have on other phones are probably running skins, which are additional aesthetic and technological components that consume extra resources and aren’t very well optimized, depleting the battery, slowing processors, and leaving fewer accessible memory resources.
- The OS offers a ton of features designed to increase your privacy. These include on-demand turning off sensors, cameras, microphones, and other devices. While some applications leave flaws that hackers can attack, some use this to capture excessive amounts of personal data. That’s gone with GrapheneOS.
- Only Pixel phones with Titan business-grade CPUs can run it. Due to the fact that all user data is encrypted by default, even the most advanced attacks like brute force ones pose no threat. Only computers and mobile devices with suitable hardware capabilities can run GrapheneOS. The operating system takes care of the software side, but it also has to coordinate with the hardware that is available.
Disadvantages
- Only Google Pixel smartphones can be used to install GrapheneOS. Since not everyone can afford a Pixel phone, this is somewhat of a restriction. not just due to the cost, but also because of preferences. Users might be more eager to give it a try if it were available across all versions of Android.
- Installs slowly and requires hard work. An Android smartphone comes pre-installed and ready to use. All you have to do is sign in and finish the straightforward setup. Although installing GrapheneOS doesn’t take long (it only takes about 10 minutes), it still needs some preparation and is probably going to violate your warranty.
- Unreleased features include some that are currently under development. This is to be expected while using any new program, but it is still important to note.
- There is not a large development crew. At the same time, this is both a pro and a drawback. Because of their small size, the team is better able to respond quickly, be more flexible, and offer new features and issue fixes much more quickly than large corporations like Google or Samsung. On the other side, it also implies that they lack the same resources to address significant issues or create brand-new features that are comparable in scale. But the group is cognizant of this and prioritizes depth and quality above quantity. A program that accomplishes practically everything exceptionally well is the end outcome.
Devices supported by Graphene OS
The following devices are officially supported by GrapheneOS in production:
- Pixel 6a (bluejay)
- Pixel 6 Pro (raven)
- Pixel 6 (oriole)
- Pixel 5a (barbet)
- Pixel 5 (redfin)
- Pixel 4a (5G) (bramble)
- Pixel 4a (sunfish)
- Pixel 4 XL (coral)
- Pixel 4 (flame)
If you have a smartphone, should you install GrapheneOS?
Depending on who you are, yes. A mobile phone that is less susceptible to monitoring could be interesting to people who need a more secure system, work with sensitive information, or are politically exposed (such as activists, lawmakers, or journalists).
If they do want, more experienced users and programmers can also explore. However, the majority of individuals would disagree with that statement.
There is no large firm supporting GrapheneOS, thus the developers might easily leave the project, leaving you with an out-of-date phone even if the system has been updated for more than three years.
If you own a Pixel phone and disagree with Google’s monopolistic stance, you might want to test GrapheneOS. The best course of action for frequent users is to stick with the large operating systems because they are less likely to cause them headaches.
Installation
There are two installation procedures that are supported by GrapheneOS. The command-line installation manual is intended for more sophisticated users, although the WebUSB-based installer is suggested for most people.
They highly advise utilizing one of the authorized installation procedures. Third-party installation manuals can contain outdated information, bad advice, and inaccuracies.
Use the official documentation if you want a more thorough installation approach.
Conclusion
In summary, anyone searching for more security and privacy can try Graphene OS.
It’s also a sensible alternative for people who want a phone that is better optimized and doesn’t enable tech or other organizations to benefit from the use of their personal information.
And the creators of Graphene OS think that Google Pixel phones are the only Android smartphones that now offer a sufficient security baseline that can be further improved with our hardening and features, Graphene OS operates on Pixel phones.
It mainly focuses on underpinning hardware and software solutions, such as data storage, data encryption, etc.
