Why Apache Software License? ... For userspace (that is, non-kernel) software, we do in fact prefer ASL2.0 (and similar licenses like BSD, MIT, etc.) over other licenses such as LGPL. Android is about freedom and choice. The purpose of Android is promote openness in the mobile world, but we don't believe it's possible to predict or dictate all the uses to which people will want to put our software. So, while we encourage everyone to make devices that are open and modifiable, we don't believe it is our place to force them to do so. Using LGPL libraries would often force them to do so.}}

The Nokia X platform was a Linux-based mobile operating system and software platform originally developed by Nokia, and subsequently by Microsoft Mobile. Introduced on 24 February 2014, it was forked from Android and used on all the devices of the Nokia X family. It was also the next Nokia Linux project after the ill-fated MeeGo.

On 17 July 2014, after the acquisition of Nokia's devices unit, Microsoft announced that no more Nokia X smartphones would be introduced, marking the end of the Nokia X platform within only a few months after its introduction.{{cite news|url=https://www.theverge.com/2014/7/17/5911909/microsoft-kills-off-its-nokia-android-phones |title=Microsoft kills off its Nokia Android phones |publisher=The Verge |date=2014-04-08}} The phones were succeeded by low-cost Lumia devices under the Microsoft Mobile brand name.{{cite web |url=http://www.microsoft.com/en-in/mobile/phone/lumia435-dual-sim/ |title=Microsoft Lumia 435 Dual SIM - Smartphones - Microsoft - India |website=www.microsoft.com |url-status=dead |archive-url=https://web.archive.org/web/20150121063101/http://www.microsoft.com/en-in/mobile/phone/lumia435-dual-sim |archive-date=2015-01-21}} Microsoft did not release an Android-based device under their own brand until 2020, in the form of the foldable Surface Duo.{{Cite web|url=https://www.theverge.com/2019/10/2/20895128/microsoft-surface-duo-phone-foldable-screen-features-specs-price-release-date|title=Microsoft surprises with new foldable Surface Duo phone running Android|first=Chaim|last=Gartenberg|date=October 2, 2019|website=The Verge}}
