Another day, another modder shoehorning the newest Android build to legacy devices.

An unofficial port of One UI 4.1 is now available for the Exynos variants of the Samsung Galaxy S9, Galaxy S9 Plus, and the Galaxy Note 9.

Samsung has been quite generous with delivering the One UI 4.1 update. Aside from the flagships, the Korean OEM rolled out the new skin to affordable offerings like the Galaxy Note 10 Lite as well. That phone is powered by the Exynos 9810 processor, a 10nm octa-core SoC from 2018 that also powered the international variant of the Galaxy S9 and Galaxy Note 9. Unfortunately, these devices didn't even receive the Android 11 update from Samsung, although both of them are theoretically capable of running it. This prompted XDA Recognized Developer AlexisXDA to port the One UI 4.1-flavored Android 12 firmware to the Galaxy S9 and the Galaxy Note 9.

The Samsung Galaxy S9, S9 Plus, and the Galaxy Note 9 were the company’s 2018 flagship smartphones, and the three devices are still poised to receive security updates. While the Korean OEM has committed to deliver up to 3 generations of Android OS updates, the policy only applies to flagship models from the Galaxy S10 onward. As a result, both the Galaxy S9 and Galaxy Note 9 are officially stuck with Android 10. Thankfully, these devices still have quite the aftermarket development support on our forums, and a developer has now released the first set of official builds of the ArrowOS custom ROM based on Android 12 for them.

Just a few weeks ago, we showcased an unofficial port of One UI 3.1 based on Android 11 for the Exynos variant of the Samsung Galaxy Note 9. This was possible thanks to the work that XDA Recognized Developer AlexisXDA put in to get it to boot by using a modified system image from the Galaxy Note 10 Lite. Known as Noble ROM, this port has created quite a buzz in the Galaxy Note 9 community. Now, Noble ROM 1.1 has arrived and Samsung Galaxy S9 owners can now also try out the firmware on their phones.

For long, Samsung has had to face criticism for its sluggish approach in rolling out software updates, especially for older devices. That has changed to a fair bit in 2020, as nowadays the company frequently outperforms Google when it comes to delivering monthly security patch updates. For example, the Galaxy S20 lineup was the first to receive the December 2020 Android security patches nearly three weeks ago as part of the One UI 3.0 public beta program. Now, Samsung has brought the December 2020 patchset to the stable channel of One UI, starting with the Galaxy S9 and the Galaxy S20 FE.

If you consider yourself a true flashaholic, then the name "Resurrection Remix" should ring a bell. The custom ROM is known for its style and customizability, while its foundation is based on bits and pieces from LineageOS, Pixel Experience, and OmniROM. The developers started rebasing the project on top of Android 10 a few months ago, and they are now confident enough to remove the beta tag. The Resurrection Remix team has recently announced its first set of stable builds based on Android 10 for a bunch of devices, including several Xiaomi smartphones and a few others from ASUS, OnePlus, Samsung, and other OEMs.

Samsung has gotten considerably better at delivering updates to its phones in the last few years. The Galaxy S9 series was one of the first to see this improvement with the Android Pie update. The Galaxy S9/S9+ received Android 10 earlier this year in the form of One UI 2.0, and now One UI 2.1 is rolling out as well.

TWRP is now officially available for the Exynos Samsung Galaxy Note 9, Xiaomi Mi 8 SE, and Mi Translator

Official TWRP support has been added for the Exynos variant of the Samsung Galaxy Note 9, the Xiaomi Mi 8 SE, and the Xiaomi Mi Translator.

By 

Android 10's recovery implementation and the introduction of the "super" partition containing multiple dynamically resizable partitions has considerably slowed down the process of porting TWRP to devices running Android 10 out of the box. However, older non-Pixel phones that have been updated to Android 10 via OTA are not affected by those changes because they are not required to migrate to the new super partition scheme. Owing to this, XDA Recognized Developer corsicanu has brought official TWRP support for the Exynos Samsung Galaxy Note 9 with full compatibility with the One UI 2.0/Android 10 firmware. In addition, XDA Senior Member TingyiChen has brought support to the Xiaomi Mi 8 SE and Mi Translator devices.

Samsung later rolled out the One UI 2.1 update to the Galaxy S10, Galaxy Note 10, Galaxy Fold, Galaxy S10 Lite, Galaxy Note 10 Lite, and the Galaxy Tab S6. Although Samsung has yet to officially roll out the update to the Galaxy Note 9 or Galaxy S9, owners of these devices can enjoy all the goodness of One UI 2.1 thanks to the work of XDA Recognized Developer AlexisXDA.

LineageOS is one of the most popular custom ROMs available for Android devices, and the team behind the project recently released the first LineageOS 17.1 builds based on Android 10. A handful of Google devices, such as the original Pixel lineup and the Google Nexus 6, couldn't make it to the initial roster, but eventually secured spots a few days later.  Now, the LineageOS team has extended support for a few more devices, including the Exynos Samsung Galaxy S9, Galaxy S9+, Galaxy Note 9, and the Realme 2 Pro.

Developers have exploited the Samsung Galaxy S9 and Note 9 to get root access on the Snapdragon models

Developers have figured out how to root the Snapdragon models of the Samsung Galaxy S9 and Galaxy Note 9 thanks to an exploit, but there's a catch.

Samsung phones sold in the U.S. are notoriously difficult to root. Samsung Knox makes rooting especially annoying, and it tends to break a lot of things if you do manage to get root. Users in the U.S. can't even unlock the bootloader to root their devices in the first place. Every once in awhile, though, developers figure out an exploit that allows us to root. The Snapdragon Galaxy S7, Snapdragon Galaxy S8, and Snapdragon Galaxy Note 8 were possible to root using exploits, for example. The same developers behind the SamPWND exploit for the S8/Note 8 are back again with exploits that allow for root access on the Snapdragon Galaxy S9, Galaxy S9+ and Galaxy Note 9 — although there is a catch.

Stable Android 10 rolling out to the Samsung Galaxy S9/S9+

Samsung has started rolling out Android 10 for the Samsung Galaxy S9 and Galaxy S9+ in Germany as well as for Xfinity Mobile users in the US.

In the past, Samsung used to take many months to roll out new Android version updates even to its flagship phones. Since 2018, however, the company has significantly improved its record in this field. Project Treble's contribution has made itself felt. Before, flagship phones like the Samsung Galaxy S8 and the Samsung Galaxy Note 8 could see five-six months pass before receiving their Android 8.0 Oreo update, for example. This was improved with the Samsung Galaxy S9 series and the Android 9 Pie update. The pace of improvement was kept up in 2019 and Samsung was quicker than ever to first roll out an Android 10-based One UI 2.0 beta program for the Galaxy S10 series. The Galaxy S10 phones were the first to get the stable update, and the same was later rolled out for the Samsung Galaxy Note 10 phones. The company hasn't forgotten its older flagships. The Galaxy S9 series received a One UI 2.0 beta at the end of November. Now, Samsung has started rolling out the stable Android 10 update for Galaxy S9 and Galaxy S9+ users in Germany as well as for Xfinity Mobile users in the US.

The one thing that everyone with a smartphone fears is the dreaded cracked screen. If you've used smartphones for a while, there's a very good chance it has happened to you. While it is technically possible to repair a cracked screen on your own or have someone else do it, most people don't. One of the big reasons for that is cost, but Sprint is fixing that for several recent Samsung Galaxy models.

Samsung Galaxy S9 Note 9 DeX Support

The Samsung Galaxy S9 and Note 9 have received One UI 2.0 updates based on Android 10 which also brings DeX for PC support to the devices.

Shortly after the launch of the Galaxy Note 10 last year, Samsung introduced the new DeX integration with Windows and Mac PCs for the device. The feature was soon ported over to the Galaxy S10 series and there were rumors that the company was planning on extending support to its flagship lineup from 2018 with the One UI 2.0 update. Now, with the rollout of the Android 10 beta update for the Samsung Galaxy S9 series and stable update for the Note 9, it's essentially been confirmed that DeX for PC is supported on Samsung's 2018 flagships.

This feature lets you stream games from your computer to your phone. It's a really great service, especially as we head into the era of 5G connectivity when apps need a lot of bandwidth and low latency.
