Samsung and T-Mobile, in particular, seem to be having some issues with their software update releases in recent weeks. Samsung recently had to temporarily halt the release of Oreo for the Galaxy S7 and Galaxy S7 edge due to boot loop issues while T-Mobile put the Oreo update for the Galaxy Note 8 on hold last month before eventually rolling it out a couple of weeks later.
That wasn't the only update that T-Mobile paused in April. It rolled out a firmware update for the Galaxy S9 and Galaxy S9+ on April 13 that was put on hold the very next day. It has been over a month and there's still no word from the carrier when this update will be out again.
Still unclear when the rollout will resume
T-Mobile released G960USQU2ARC6 and G965USQU2ARC6 for the Galaxy S9 and Galaxy S9+ last month. Even though the firmware was released in the second week of April and believed to feature the latest security patch, it actually came with the March 2018 security patch.
It was initially believed that the firmware update brought the April 2018 security patch because the changelog mentioned that the update included Android security updates and bug fixes. Nevertheless, it was later confirmed that this firmware version didn't bring the latest security maintenance release.
Soon after the update was sent out over-the-air, some Galaxy S9 and Galaxy S9+ owners started complaining about their devices getting stuck in a boot loop after installing the update. This caused T-Mobile to pause the rollout the very next day. If you open the support pages for both handsets on T-Mobile's website right now they mention that the update was paused on April 14 and is still “Temporarily on hold.”
We have highlighted before that there's a build floating around with version number G965USQS2ARD3 that does feature the April 2018 patch but T-Mobile hasn't rolled it out as yet so it's not official. T-Mobile is yet to confirm when it's going to release a newer build to finally update these devices from the March security patch.
The latest security maintenance release for the month of May 2018 is out already so it would make sense for T-Mobile to develop a fresh build for the Galaxy S9 and Galaxy S9+ now. It can't be said for sure, though, when it's going to start rolling one out.
