## Summary
An Android distribution is an operating system built on Google’s open-source Android codebase that has been modified, rebranded, or extended by a third party for specific devices or use-cases. Like Linux distributions, these variants range from manufacturer skins (MIUI, OneUI) to privacy-focused forks (GrapheneOS, /e/OS) and community ROMs (LineageOS, crDroid).

## Key Facts
- Sub-classified as both a Linux distribution and a mobile operating system.
- First community forks appeared around 2010 (Replicant, MIUI).
- At least 30 notable distributions are documented, with sitelink counts ranging from 1 (Bliss OS, emteria.OS) to 39 (MIUI).
- Inception years span 2010 (Replicant, MIUI) to 2023 (Xiaomi HyperOS).
- Some distributions target PCs (Bliss OS, Remix OS), while most run on ARM smartphones and tablets.
- Several projects are explicitly security-oriented: GrapheneOS (2014, Canada), CopperheadOS, DivestOS (2014–discontinued).
- LineageOS for microG (2017) and /e/OS ship with open-source Google-service replacements pre-installed.

## FAQs
### Q: What makes an Android distribution different from stock Android?
A: A distribution re-uses Android’s open-source core (AOSP) but adds, removes, or replaces code—custom UI layers, pre-installed apps, privacy hardening, or drivers for extra hardware—creating a distinct OS image that must be flashed onto devices.

### Q: Are Android distributions legal?
A: Yes. Android’s permissive open-source licensing (Apache 2.0, GPL for kernel) allows anyone to compile and redistribute modified versions as long as they comply with license obligations, such as publishing kernel source where required.

### Q: Which distribution should I use for maximum privacy?
A: GrapheneOS (active since 2014) is widely cited for its hardened kernel, sandbox improvements, and removal of Google telemetry; /e/OS and DivestOS also focus on de-Googling while maintaining app compatibility.

### Q: Do manufacturers maintain their own Android distributions?
A: Yes—Xiaomi (MIUI since 2010, HyperOS since 2023), Huawei (EMUI since 2012), OnePlus (OxygenOS since 2015), and others ship devices with heavily modified Android distributions that include proprietary services and UI skins.

## Why It Matters
Android distributions let vendors differentiate devices, extend support lifetimes, and serve niche user needs that Google’s commercial release does not address. For consumers, they translate into wider choice: heavily customized UIs, longer security updates for old phones, or completely de-Googled environments that respect privacy. For the industry, they lower barrier-to-entry: startups can launch smartphones without writing an OS from scratch, while regions such as India have fostered local OS efforts (Indus OS) to support indigenous languages and app ecosystems. The open-source nature also underpins a vibrant aftermarket: community ROMs keep devices alive long after vendors abandon them, reducing e-waste and giving power users granular control. Security researchers, in turn, use hardened forks like GrapheneOS to raise the baseline for mobile protection, influencing upstream Android security architecture. Collectively, Android distributions demonstrate how open-source licensing can create an entire galaxy of purpose-built mobile operating systems from a single codebase.

## Notable For
- Largest mobile OS fork ecosystem—30+ documented variants, far exceeding any other consumer OS.
- Hosts both the most widely used third-party mobile UI (MIUI, 39 Wikipedia language editions) and ultra-niche privacy ROMs (e.g., 1-sitelink LineageOS for microG).
- Only major mobile platform where end-users can legally replace the vendor OS with a community-maintained distribution (LineageOS, crDroid, etc.).
- Spawned full desktop-style Android-for-PC forks (Remix OS, Bliss OS) years before Google’s own desktop efforts.
- Enabled regionalized platforms such as Indus OS, supporting multiple Indian languages out-of-the-box.

## Body
### Definition and classification
An Android distribution is any operating system that retains Android’s application framework and at least its Linux kernel but modifies the rest of the stack. Per source data, every listed variant is formally a subclass of both “Linux distribution” and “mobile operating system,” giving it the heritage of GNU/Linux while targeting touch-first mobile hardware.

### Historical timeline
- 2010 – Replicant and MIUI launch, establishing free-software and vendor-skin poles.
- 2012 – Flyme and EMUI appear, Chinese OEMs begin heavy customization.
- 2014 – GrapheneOS progenitor (initial release), DivestOS and Remix OS start; latter pioneers Android-on-Intel-PCs.
- 2015 – OxygenOS debuts with OnePlus One.
- 2017 – Bliss OS and LineageOS for microG created, addressing PC and de-Googled niches.
- 2023 – Xiaomi HyperOS replaces MIUI as Xiaomi’s Android-based stack.

### Variants by purpose
1. Vendor skins: MIUI, EMUI, ColorOS, Flyme, MagicOS, Smartisan OS—ship pre-installed, emphasize UI branding and services.
2. Security hardened: GrapheneOS, CopperheadOS, DivestOS (discontinued) — strip Google APIs, add exploit mitigations.
3. Community ROMs: LineageOS, Paranoid Android, Resurrection Remix, crDroid, AICP, Dirty Unicorns—offer update longevity and customization.
4. Google-free convenience: /e/OS, LineageOS for microG—bundle microG replacement services.
5. PC-oriented: Remix OS (2014), Bliss OS (2017) — add windowing and keyboard support for x86 laptops/desktops.

### Technical notes
All distributions reuse AOSP’s core frameworks (ART runtime, Binder IPC, HAL structure). Most replace the stock launcher and SystemUI; many ship patched kernels for wider SoC support. Because Google Mobile Services (GMS) is proprietary, de-Googled forks either omit it (Replicant), offer microG (/e/OS), or advise sandboxed installation (GrapheneOS).
