Generally, the phones included on this list contain copyleft software other than the Linux kernel, and minimal closed-source component drivers (see section above). Android-based devices do not appear on this list because of the heavy use of proprietary components, particularly drivers and applications. Ubuntu Touch is a mobile version of the Ubuntu operating system for mobile devices. However, unlike other 'flavors' of Ubuntu, it is more accurately an extract of parts of Ubuntu. It is adapted to run naturally in a mobile, touch-screen environment but is also capable of functioning as a desktop computer while in 'desktop mode'. XDA Developers was founded by developers, for developers. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding. The developers are also working on their plans to create a Linux-based phone operating system that’ll be able to replace Android and iOS. Mobile, postmarketOS is another Linux phone project. XDA Developers was founded by developers, for developers. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality.

Mailing list rules

We love simplicity and hate restrictions, so we keep our policies minimal.The rules below describe what's expected of subscribers to the Android mailinglists.

• Be friendly: Showing courtesy and respect to others is avital part of the Android culture, and we expect everyone participating in theAndroid community to join us in accepting nothing less. Being courteous doesn'tmean that we can't constructively disagree with each other, but it does meanthat we must be polite when we do so. There's never a reason to beantagonistic or dismissive toward anyone; if you think there is, think againbefore you post. Mobile development is serious business, but it's also a lotof fun. Let's keep it that way. Let's strive to be one of the friendliestcommunities in all of open source.
• Allowed discussion topics: Most of our groups are for technicaldiscussions of Android or users helping each other. Generally we don't puthard restrictions on the topics discussed in the group. As long as the topicis relevant to Android in some way, it's welcome on our groups. We welcomeannouncements and discussion of products, libraries, publications, and otherinteresting Android-related news, but don't cross-post. Post only tothe most relevant group for your message. We even welcome (polite!) discussionof articles and ideas critical of Android—after all, we can't improve ifwe don't listen.
• Working Lists: Some of our groups are considered working lists,by which we mean that the list is intended to be used in support of thecompletion of specific tasks. On these groups, we don't welcome off-topicconversations, and usually ask you to take general discussions to adifferent list. Because these are lists where people are trying to get workdone, we're pretty aggressive about keeping the noise level low. We askthat you respect our contributors' time and keep general discussions toappropriate lists.
• Spam: We hate spam almost as passionately as we love courtesy andrespect, so we reserve the right to limit discussions that amount to spam.Outright spam results in the spammer being immediately and permanentlybanned from the list.

The most important rule is friendliness. Remember: disrespect and rudenessaren't welcome in our community under any circumstances. We don't have aformal policy on dealing with troublemakers, and we hope that we never need one.That said, we pledge to do our best to be fair, and we always try towarn someone before banning them.

Contacting the moderators

If you see anyone being rude, call them out on it. This is your group, too,and you don't have to accept someone else being disrespectful just because itwasn't directed at you. Just remember to be polite and courteous yourself!Don't add fuel to the fire.

If you see an outrageous violation, want to report spam, feel stronglyabout something, or just want to chat, then contact the mailing list owners.It's what we're here for!
