These are results for phones that we are no longer tracking every month. They are presented here for historical/reference purposes, and most (if not all) of these devices have been discontinued for a long time.
Samsung Galaxy S10: 8.0
Samsung used to be much worse with security and OS updates, but the Galaxy S10 was a turning point for the company. The S10 received security updates in a timely manner, but and was also among the first phones to receive Android 10. The phone also managed to maintain a high score for well over a year, while most competing phones from 2019 slipped behind.
|Tracked data||Mar 2019 - Nov 2020|
|Months skipped||2 months|
|Average delay||7 days|
The Galaxy S10 only missed two security updates since its release in early 2019: the patches for June and July 2019 were included in an August update. However, the S10's typical delay from when Google's security bulletins were published is the main reason it fell slightly behind other devices.
Nokia 9 PureView: 7.5
The Nokia 9 PureView is the closest thing HMD Global had to a flagship Android device in 2019, and even though the phone suffered from camera and fingerprint reader bugs when it launched, the PureView's security update record was acceptable. According to our data, the PureView has only skipped one month since its release — the May 2019 patch was never rolled out (Nokia combined it with the June patches).
|Tracked data||Jan. 2019 - Nov. 2020|
|Months skipped||1 month|
|Average delay||14 days|
While there were a few instances of Nokia rolling out the update in the first week of the month, most patches were released around two weeks later. For example, the February 2020 update rolled out on February 24th, the December 2019 patches were released on December 31st, and so on.
LG G8 ThinQ: 2.5
LG's mainstream 2019 flagship, the G8 ThinQ, skipped several months of patches and had a high average delay. However, we were using rollout dates for the AT&T model, because there wasn't enough public data about the US unlocked version.
|Tracked data||Mar. 2019 - Nov. 2020|
|Months skipped||9 months|
|Average delay||31 days|
The added step of carrier approval could be adding some delay, but the frequency of patches is the G8's primary issue. There were no updates at all from late September 2019 until mid-February 2020, and the February update only had the December patches.
Motorola Moto Z4: 1.0
The Moto Z4 had an average update delay of over a month, but it was more likely for Z4 owners to not get an update at all. The Z4's first update came in mid-July (containing May patches), then there were no updates at all until mid-November. Oh, and the November update was two months behind in security patches.
|Tracked data||June 2019 - Nov. 2020|
|Months skipped||10 months|
|Average delay||34 days|
