So, Samsung started rolling out One UI 7, based on Android 15. It’s supposed to bring smoother animations, a new look, and some Galaxy AI features like live call transcripts and writing tools. Pretty cool on paper.
But unfortunately, the rollout hasn’t gone perfectly. It launched on devices like the Galaxy S24, S23, S22, Fold6, Flip6, and a few tablets too. And right after it dropped in early April, problems started showing up, especially for S24 users in South Korea. Some of them literally couldn’t unlock their phones after updating. Not great.
Samsung had to pull the update from their servers around April 11–12, then fixed it and released a new build (BYD9) by April 17. That version solved the lock issue for most people. But bugs are still being reported.
Here’s what people are complaining about
Some users have made complaints on platforms like Reddit, Samsung forums, and posts on X — and some patterns are popping up:
Update won’t install or download properly
A lot of Galaxy S24 Ultra users say they see errors like:
“Couldn’t install update. Try again later.”
In some cases, the update downloads fully but just refuses to install. Others say it pauses randomly. Seems like Samsung’s servers got hammered when everyone tried downloading at once. A few people fixed it by pausing the download, restarting their phone, and trying again after a couple of hours.
Lock screen issues
The original rollout caused some users to get locked out of their phones completely. That’s mostly fixed with the newer update, but a few folks still say their fingerprint or face unlock doesn’t work sometimes. One weird bug? Secure Folder showing hidden pics in the Gallery. Not everyone sees it, but it’s concerning.
Home screen layout gets messed up (especially on tablets)
If you use a horizontal layout or big widgets on your Galaxy Tab S9 or S10, you might notice the layout is broken after updating. Samsung even warned about this.
Quick fix: Use Good Lock’s Home Up module and switch to a vertical grid layout like 5×7 before updating.
SwiftKey warning
Using Microsoft SwiftKey as your default keyboard (with password lock) might stop your device from unlocking after updating. Samsung said to use Samsung Keyboard or Gboard instead. You could lose access to your device if you don’t.
Battery draining/phone feels sluggish
Some folks say battery life got worse after the update. Others noticed lag on mid-range phones. My S25 Ultra didn’t take a huge hit, but I did see a little more drain after the April patch. It could just be background processes adjusting to the new system.
Past Update Issues
Samsung has a track record with buggy updates.
- One UI 6.1: S22 users had boot loops, overheating, and in some cases, dead phones. S23 owners had issues with touchscreens and charging capped at 15W.
- One UI 5: Some tablets became super slow after the update. People hated the app drawer layout and random Wallet popups.
- Green line issue: Some Galaxy S21 and S22 Ultra owners reported green lines showing up after updating — not necessarily tied to One UI 7, but it’s been an ongoing thing. Samsung offers free screen replacements in places like India if that happens.
What you can try if you’re stuck
If you’ve already installed One UI 7 and something feels off, try these:
- Update won’t download? Pause it, restart the phone, and try again later.
- Unlock issues? Make sure you’re not using SwiftKey. Test your fingerprint/PIN before and after updating.
- Weird home screen after update? Use Good Lock to change the layout back to vertical (5×7).
- Performance/battery problems? Give it a few days. Also, update your apps (Galaxy Store + Play Store), and clear cache if needed.
Still no luck? Hit up Samsung Support or check with a service center. For green lines, see if your device qualifies for a free screen replacement.

Did you get One UI 7 already? Did it go smoothly? Or did things break?
