Samsung offers free repairs for Soundbars bricked by faulty firmware

Certain Samsung soundbars stopped functioning following a firmware update. Now, Samsung has acknowledged the faulty firmware, which bricked certain 2024 soundbar devices and offering free repairs to consumers.
According to TheVerge, Samsung confirmed that a “software update error” has bricked “certain 2024 soundbar devices.”
Notably, the software fault was mainly reported on flagship HW-Q990D models in many parts of the world. However, people reported problems with Samsung’s HW-Q800D and HW-S801D soundbars as well.
The recent firmware was installed itself (due to auto-install settings). The bug rendered soundbars unresponsive and inaccessible from Samsung SmartThings. As connection lost entirely, users were also unable to performe factory reset.
Users having affected soundbars now required to visit their nearest Samsung service center. The issue can only be addressed with a physical repair. However, the company will bear the cost even if your device is now out of warranty.
Jim Kiczek, head of audio at Samsung Electronics America in a statement acknowledged the problem and announced that Samsung is “offering free repairs for all affected units – regardless of warranty status.”

Samsung Galaxy S25 supports Android’s nifty Instant Hotspot feature (One UI 7)

The Galaxy S25 series is Samsung’s first device to support Android’s Instant Hotspot feature. Samsung already offers a nifty internet-sharing feature called Auto Hotspot, which is exclusively functional across Galaxy devices.
Android’s Instant Hotspot deals with this restriction but it’s presently available on the Galaxy S25 series. As spotted by AndroidAuthority, Samsung’s newest flagship smartphones come with Instant Hotspot feature.
The feature works as described by Google on its Android Help website. When enabled, the system displays a notification on your Android tablet asking if you want to use your smartphone’s hotspot.
As soon as you hit the “connect button” a temporary hotspot connection gets established. You can also connect with your phone’s hotspot using the Internet settings panel on your tablet.
One UI 7 brings Instant Hotspot
The Galaxy S25 series comes with Android 15-based One UI 7 preinstalled. The new OS seems to be bringing the Instant Hotspot feature to Galaxy devices. Beta participants have confirmed the existence of this feature on older models.
One UI 7 Beta is available on a handful of Samsung devices including the Galaxy S24 and S24 series, the Galaxy Tab S10 series, the Galaxy Z Flip 6, and Z Fold 6. Samsung is expected to start Stable One UI 7 update in April week 1st.

Samsung won users trust with One UI 7 release date—then lost it

For Samsung fans like me, the last year has felt like forever. We’ve been waiting and waiting for One UI 7, the big Android 15 update that’s been so close yet so far. The latest update promised refreshed interfaces, smarter AI features, and a smoother Galaxy experience. After months of delays, beta builds, and uncountable rumors, we finally got what we wanted: an official release date.
On March 18, 2025, Samsung US dropped the information in an official blog post—One UI 7 would roll out to the Galaxy S24 series, Z Fold 6, and Z Flip 6 on April 10. We all let out a big sigh of relief. Trust in Samsung, which had been shaky from all the quiet delays, came rushing back. The company gave us something we could count on. But now, just like that, it disappeared.
By March 21—today, as I write this—the official blog post had vanished from Samsung’s US Newsroom portal. No explanation, no replacement date, no nothing. As a loyal Galaxy user, I felt totally let down. What started as a big win turned into a huge letdown. Samsung had earned my trust, then lost it in under 72 hours.
To get why this hurts so much, let’s go back a bit. One UI 7 has been a slow tease. After starting the beta program for the Galaxy S24 series in December last year, we were waiting for the official announcement. The wait wasn’t just long—it was brutal. Each beta update got our hopes up, but the stable version stayed out of reach. By the start of 2025, we were all done waiting. Then, this week, things changed.
Samsung said (officially) the update would hit globally on April 7, with the US getting it on April 10. It wasn’t just a date—it was a rescue, I am using my opinion here. After all those delays, we finally had something solid. I even planned my week around it, picturing the moment I’d download it, try the new stuff, and feel that Galaxy love again.
So what’s going on? Why would Samsung pull the post that just got us excited again? People are guessing left and right. Some think there’s a delay—maybe the US rollout experienced some issues, even though the global dates seem fine. Others wonder if the April 10 date was a mistake, accidentally published before final confirmation. Samsung’s not saying a word about it, and that’s just making everyone more curious. Right now, there’s no new date, no official update—just a big question mark leaving us stuck again.
It hurts because it’s not just about a missing post. It’s like all the excitement just faded away. For a second, Samsung had us thinking they’d figured it out after all the waiting, that they were ready to deliver. As a user, I’m wondering: Can I count on Samsung to stick to their words? Will One UI 7 arrive in April, or are we back to square one? Not knowing feels worse than the wait ever did.

I still want to stick with Samsung. My Galaxy ecosystem—my S24 Ultra, my Watch, my Buds—is not easy to walk away from, right? One UI 7 with its cool new look and smart upgrades, still gets me excited. But this latest mess, no words.
Samsung earned our trust with that release date. Then lost it by pulling that post with no explanation. It’s up to you now. Tell us something clear. Give us a new date—or at least tell us why.

Samsung launches creative campaign for Galaxy A56 Enterprise Edition

Samsung has launched a new creative campaign with the Galaxy A56 Enterprise Edition. Samsung UK has brought to life the dramatic impact of tech fails highlighted by the results by creating a series of posters inspired by action, drama, and sci-fi genres.
The company has surveyed SMEs across the United Kingdom. The results disclosed that SMEs lose nearly £300k yearly due to business tech issues. The poll of 1,000 SME owners highlighted they spend £3,200 each year on repairs and updates.

Annika Bizon, Mobile Experience VP of Product and Marketing said: “Having issues with your work devices can cause a mountain of problems for business, even leading to a loss in revenue. We want to have SME owners back by offering Next Business Day Replacement with our Galaxy A Series Enterprise Edition range – ensuring all the productivity with none of the setbacks.”
