Say Goodbye to Bloatware and End-of-Upda

Say Goodbye to Bloatware and End-of-Updates: LineageOS, the "Life-Extending Tool" for Android Enthusiasts

 

In the Android ecosystem, beyond manufacturer-customized systems like MIUI and ColorOS, there exists a group of third-party operating systems centered around "open source, freedom, and customization" — and LineageOS stands out as one of the most representative among them. It carries on the legacy of the classic custom ROM CyanogenMod (CM for short), and with its compatibility across multiple devices and high level of customization, it has become a "life-extending tool" in the eyes of countless mobile enthusiasts. It is also a popular entry choice for many looking to experience pure Android. Today, let's take a closer look at this open-source system that breathes new life into old phones and brings Android back to its essence.

 

The story of LineageOS begins with CyanogenMod, one of the "pioneers" in the field of custom Android ROMs. In 2009, developer Steve Kondik (better known by his nickname "Cyanogen") launched CyanogenMod based on the Android Open Source Project (AOSP). Initially, it was created simply to fix official system bugs and optimize performance for the then HTC G1 phone. However, its features — "de-bloated, highly customizable, and widely compatible" — quickly attracted a large user base. At its peak, it supported nearly 200 devices and even partnered with manufacturers like Samsung and OnePlus for pre-installation, establishing itself as a benchmark in the third-party ROM space. By December 2016, though, due to strategic adjustments by its parent company Cyanogen Inc., the CyanogenMod project was officially discontinued. To prevent this open-source ecosystem from vanishing, core members of the original CM team quickly formed a new team and officially released LineageOS on December 24, 2016. The name "Lineage" signifies the inheritance of CM's spirit. The first version, based on Android 7.1, not only retained CM's core functions but also gradually grew into an "evergreen" in the open-source Android field through more standardized development processes and community management. As of 2024, LineageOS has been updated to LineageOS 21 (based on Android 14), with a steady increase in supported devices. By the end of 2023, the number of active global devices exceeded 1.5 million, making it one of the most mainstream third-party open-source Android systems today.

 

LineageOS has maintained its vitality over the long term, primarily because it accurately addresses users' needs for "pure Android" and "freedom of control." Its key features can be viewed from several angles. First, it returns to purity: unlike manufacturer-customized systems, LineageOS strictly adheres to the AOSP core, pre-installing only essential apps such as phone, messaging, and file management by default — no third-party bloatware included. Its interface is clean and minimalist, with an operating logic highly consistent with stock Android. This not only avoids the annoyance of ad pop-ups but also significantly reduces system resource usage. For many old phones released 3–5 years ago, after installing LineageOS, issues like lagging and poor battery life are noticeably improved; some can even run the latest apps smoothly. Second, it offers high customization: it comes with a mature "customization toolbox" that allows extensive adjustments without rooting. For example, in terms of interface customization, it supports a theme engine, icon pack replacement, font adjustments, and even lets users hide status bar icons or customize navigation bar layouts. For performance, users can adjust CPU frequency, optimize GPU rendering, and limit background processes — gamers can manually overclock to boost frame rates, while average users can underclock to extend battery life. In terms of functionality, it includes a "Privacy Protection" module for granular app permission management and restricting background location access, as well as a "Life Assistant" that provides step counting, weather widgets, and other services. It even supports further feature expansion via "Magisk modules," such as hiding root status or installing system-level plugins.

 

Furthermore, multi-device compatibility is one of LineageOS's core strengths. Unlike official systems that only support their manufacturers' new models, LineageOS's community of developers adapts the system for numerous "less popular models" and "discontinued old devices," covering brands like Google, Samsung, Sony, OnePlus, Xiaomi, and Motorola. For instance, the Xiaomi Mi 8 and OnePlus 6, released in 2018, have long stopped receiving official system updates, but LineageOS still provides LineageOS 21 (based on Android 14) for them, allowing these old devices to experience the latest Android features. Finally, it is open-source and transparent: as an open-source project, LineageOS's code is fully public, allowing anyone to view and audit it — greatly reducing the risk of "backdoors" or "malicious code." At the same time, the official team pushes regular security patches, usually monthly. While the speed of critical vulnerability fixes cannot match that of Google Pixel devices, it is much faster than the support most manufacturers offer for old models. Additionally, the LineageOS Forums are active, enabling users to quickly find solutions to problems, and developers continuously optimize adaptations based on user feedback.

 

However, LineageOS is not perfect; its strengths are as prominent as its weaknesses, so users should clarify their needs before choosing it. On the plus side, it extends device lifespan: after installing it on an old phone, users can break free from the performance limitations and end-of-updates of official systems, with significant improvements in battery life and smoothness. It also offers a high degree of freedom: users are not restricted by manufacturer-imposed feature limitations (such as hidden developer features on some brands) and can adjust settings as needed to create a personalized system. It is free of ads and bloatware, completely eliminating pre-installed promotional apps and ad pop-ups for a cleaner user experience. Its open-source and transparent nature also reduces the risk of privacy leaks, making it suitable for users sensitive to data security.

 

On the downside, the main issues lie in the technical barrier to installation and compatibility. Installing (or "flashing") LineageOS requires a certain level of technical knowledge: users need to unlock the phone's Bootloader (a process that is particularly complex for brands like Xiaomi and Samsung), followed by flashing a custom Recovery. Mistakes during these steps can render the device inoperable ("bricking" it), so novice users should proceed with caution. Some features may also be missing: due to the lack of manufacturer authorization, LineageOS typically does not support infrared remote control, wireless charging (for some models), or official camera algorithms (such as Xiaomi's Leica filters or Huawei's XMAGE). This can affect camera image quality or hardware functionality. Stability depends on device adaptation: the quality of adaptations varies greatly across models, and some less popular devices may experience compatibility issues like call static, WiFi disconnections, or fingerprint recognition failures. Additionally, Google Play Services are not pre-installed by default. While they can be installed manually, this is inconvenient for users who rely on the Google ecosystem (e.g., for overseas apps or games).

 

As of 2024, LineageOS officially supports over 150 devices, covering popular models and classic old devices from multiple brands. For example, Google Pixel series devices (Pixel 5/6/7/8 series) have the most complete adaptations and highest stability, and are prioritized for official updates. Among Xiaomi/Redmi models, the Xiaomi Mi 8, Xiaomi Mi 10, Redmi K20 Pro, and Redmi Note 8 Pro have active community adaptations and abundant tutorials. OnePlus 6/7/8 series devices, whose OxygenOS is already close to stock Android, offer excellent compatibility with LineageOS. Samsung Galaxy S10/S20 series and Note 10 series require Bootloader unlocking, and some models also need a dedicated kernel to be flashed. Sony Xperia 1/5 series devices benefit from Sony's strong support for open-source software, resulting in stable adaptations. Beyond these, models like the Motorola Edge series, HMD Global (Nokia) 7.2, and LG G8 ThinQ are also on the support list. To check if your phone is supported, visit the "Devices" page on the official LineageOS website (https://lineageos.org/), enter your device model, and you can find adaptation status and flashing tutorials.

 

LineageOS is not a "one-size-fits-all system," but it provides irreplaceable value for specific groups of users. If you have an old phone that still performs well but no longer receives official updates, and you want to use it for another 2 years; if you are tired of the ads and bloatware in manufacturer systems and want to experience pure Android; or if you enjoy customizing your phone and want to tailor system functions to your needs — then LineageOS is definitely worth trying. However, if you are a novice user worried about the risk of technical errors; if you have high requirements for camera quality or hardware features like infrared; or if you heavily rely on Google Services and do not want to install them manually — then the official manufacturer system or Google Pixel's stock system will be safer choices.

 

In an era where the Android ecosystem is becoming increasingly closed, LineageOS acts like a "gateway to freedom," safeguarding the original intention of open source while extending the lifespan of countless old devices. For enthusiasts who enjoy customizing their phones, the process of flashing LineageOS may be tedious, but the sense of accomplishment from seeing an old phone run the latest system smoothly is precisely what makes this open-source system so appealing.
