Source-derived summary

CyanogenMod is a discontinued open-source operating system for mobile devices, based on the Android mobile platform. Developed between 2009 and 2016, it is free and open-source software based on the official releases of Android by Google, with added original and third-party code, and based on a rolling release development model. Although only a subset of total CyanogenMod users elected to report their use of the firmware, on 23 March 2015, some reports indicated that over 50 million people ran CyanogenMod on their phones. It was also frequently used as a starting point by developers of other ROMs.

Editorial summary

This brief starts where responsible research should: with the source description of “CyanogenMod” as discontinued open-source mobile operating system. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current lead gives the account dated anchors—2009, 2016, 2015—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where CyanogenMod, Discontinued and open-source can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as discontinued open-source mobile operating system. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 30, 2026. The first chronological checks are 2009, 2016 and 2015.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
