If you have an older Samsung foldable phone, tablet or watch, you may soon see some new features trickling down from the latest devices. The company announced today that the One UI 5.1.1 update — Samsung’s latest custom UI sitting atop Android — will roll out soon, bringing enhancements from the Galaxy Z Fold 5, Z Flip 5, Tab S9 series and Watch 6 series to pre-2023 gear. The features will support most of Samsung’s foldable phones and its recent tablets and smartwatches.

The One UI 5.1.1 update will support a long list of recent Samsung devices, but some may have to wait. It will roll out to Samsung’s stable of foldable phones, scheduled to reach the Galaxy Z Flip 4 and Z Fold 4 “starting this month,” while the Z Fold 3, Z Flip 3, Z Fold 2 and Z Flip will receive it “sequentially” later. Tablet multitasking updates will arrive for the Galaxy Tab S8, Tab S8+, Tab S8 Ultra, Tab S7, Tab S7+, Tab S7 FE, Tab S6 Lite, Tab A8, Tab A7 Lite, Tab Active 3 and Tab Active 4 Pro. Finally, new smartwatch features will support the Galaxy Watch 5, Watch 5 Pro, Watch 4 and Watch 4 Classic.

Samsung’s foldable phone updates in One UI 5.1.1 make it easier to show or hide the Flex Mode Panel (the controls appearing on the bottom half of the screen when the phone is semi-folded). “When folding your phone in Flex Mode, the panel’s icon will float up the screen, allowing you easy access,” the company wrote. “Enjoy a more personalized Flex Mode Panel experience by simply dragging and dropping the icon on the toolbar.” In addition, Samsung says the media play bar button (now including 10-second fast forward and rewind buttons) will be more prominent and simpler to find when the Flex Mode Panel activates. You’ll also be able to press down on the timeline to scrub through media more efficiently.

Samsung is tweaking multitasking on recent tablets and foldables, making switching to multi-window from pop-up window modes easier by long-pressing the handle. It also adds two-handed drag and drop, which lets you hold your finger down on a document from one app, use your other hand to open something else and then drag the file onto it for sharing or storage. The company also says the Z Fold 4 and Tab S8’s taskbar will be faster and include more recent apps. “Now, the Taskbar enables lightning-fast task switching with access to up to four recent apps,” Samsung said.

On the smartwatch front, the company is adding sleep-tracking upgrades from the Galaxy Watch 6 to older wearables. The changes include “a more intuitive UI” with the additions of Sleep Score Factors, Sleep Consistency and Sleep Animal Symbols. Sleep Coaching will also be available on the watch without looking at your paired phone. The Galaxy Watch can also automatically adjust SmartThings home devices for a more rest-inducing ambiance at bedtime.

Smartwatches will also receive fitness updates. The Watch 6’s Personalized Heart Rate Zone feature trickles down; it analyzes your physical abilities and “defines five optimal running intensity levels to help users set their own goals based on their ability — from burning fat to high intensity workout.” The Galaxy Watch 5 and Watch 4 series will also add Irregular Heart Rhythm Notifications in the update, which could be a lifesaver for some.

Meanwhile, Track Run, which (as its name suggests) records your runs on a track, also makes its way from the Watch 6. The Galaxy Watch 5 Pro will have access to a GPX File Database for downloading map data to your watch. Finally, One UI 5.1.1. lets you control the Flip 4’s camera with a paired Galaxy Watch. A new quick-access button will let you use your watch as a remote shutter, and it also lets you switch camera modes and control zoom levels.

Astronomers have used advanced instruments to calculate a more accurate age of Maisie’s galaxy, discovered by the James Webb Space Telescope (JWST) in June 2022. Although the star system isn’t quite as old as initially estimated, it’s still one of the oldest recorded, from 390 million years after the Big Bang — making it about 13.4 billion years old. That’s a mere 70 million years younger than JADES-GS-z13-0, the (current) oldest-known system.

A team led by the University of Texas at Austin astronomer Steven Finkelstein discovered the system last summer. (The name “Maisie’s galaxy” is an ode to his daughter because they spotted it on her birthday.) The group initially estimated that it was only 290 million years after the Big Bang, but analyzing the galaxy with more advanced equipment revealed it’s about 100 million years older than that. “The exciting thing about Maisie’s galaxy is that it was one of the first distant galaxies identified by JWST, and of that set, it’s the first to actually be spectroscopically confirmed,” said Finkelstein.

The spectroscopic confirmation came courtesy of the JWST’s Near InfraRed Spectrograph (NIRSpec) conducted by the Cosmic Evolution Early Release Science Survey (CEERS). The NIRSpec “splits an object’s light into many different narrow frequencies to more accurately identify its chemical makeup, heat output, intrinsic brightness and relative motion.” Redshift — the movement of light towards longer (redder) wavelengths to indicate motion away from the observer — held the key to more accurate dating than the original photometry-based estimate. The advanced tools assigned a redshift of z=11.4 to Maisie’s galaxy, helping the researchers settle on the revised estimate of 390 million years after the Big Bang.

The astronomers also examined CEERS-93316, a galaxy initially estimated at 235 million years pre-Big Bang — which would have made it astonishingly old. After studying this system, it revealed a redshift of z=4.9, which places it at a mere one billion years after the Big Bang. The first faulty estimate about CEERS-93316 was understandable: The galaxy emitted an unusual amount of light in narrow frequency bands associated with oxygen and hydrogen, making it appear bluer than it was.

Finkelstein chalks up the miss to bad luck. “This was a kind of weird case,” he said. “Of the many tens of high redshift candidates that have been observed spectroscopically, this is the only instance of the true redshift being much less than our initial guess.” Finkelstein added, “It would have been really challenging to explain how the universe could create such a massive galaxy so soon. So, I think this was probably always the most likely outcome, because it was so extreme, so bright, at such an apparent high redshift.”

The CEERS team is now evaluating about 10 more systems that could be older than Maisie’s galaxy.
