Rating units by their report with safety updates turned out to be a bit troublesome. There are lots of variables to contemplate, together with totally different rollout dates for various nations, delays with service fashions in comparison with their unlocked equivalents (although Samsung and different OEMs typically replace their unlocked units later), and availability of first-hand data.
Whereas some firms make public bulletins the day an replace begins to roll out — for instance, OnePlus publishes a discussion board publish for every replace — most don’t. Meaning we’ve depend on person studies from social media (Twitter, Reddit, and so forth.) and impartial information protection to search out dates for releases. Most of our information concerning the Sony Xperia 1 got here from XperiaBlog, for example.
With these elements in thoughts, we determined to slim the scope of this text and set affordable tips.
First, we trimmed our information to deal with rollout dates for units in the USA. Most Android cellphone producers have totally different replace schedules for various areas, however as a result of most of our readership is predicated within the US, utilizing information about how rapidly Motorola launched an replace to a cellphone in Brazil would not be useful. In some situations, the studies did not specify what area the rollout occurred in (particularly with data posted to Reddit/Twitter), but when we discovered proof that the US launch occurred on a special date, we seemed for information elsewhere.
Second, we’re monitoring rollout dates for the carrier-unlocked variants of every cellphone, besides the place in any other case specified. We’re properly conscious that most individuals in the USA purchase their telephones straight from a service, however making an allowance for the impartial delays that every service provides to the replace course of would have made the info much less concise and useful.
Third, the beginning date for every patch is when Google printed the Android Safety Bulletin. Close to the beginning of every month, Google releases a public web page concerning the fixes included in that month’s safety replace. The publishing date of the bulletin is the baseline date we use to calculate the delay for every system. Google often supplies code for safety updates to OEMs some time earlier than the web page goes dwell, however contemplating the publish date is when most people turns into conscious of the patched bugs, it is a good place to start out.
Fourth, the info we have collected for every system begins in January 2019, or when the cellphone was launched (whichever comes final). For instance, although the Pixel three was launched in late 2018, we’re solely taking a look at updates launched since January 2019. We’re additionally not penalizing skipped months if the cellphone wasn’t launched but in that month.
Lastly, we’re solely wanting on the flagship units of every main cellphone producer that releases telephones within the US. We’re properly conscious that Xiaomi, Oppo, and different firms exist, however together with telephones from each main world cellphone maker is just too a lot for us to maintain monitor of presently.
All that’s to say there’s a little little bit of wiggle room in our outcomes. It is attainable the Twitter report of an replace was posted just a few days after the precise rollout started, or the overwhelming majority of cellphone house owners acquired a sure replace a lot later as a result of the rollout was paused.
