Still using a Redmi Note 5 or Redmi 5 Plus in 2025? You’re in for a treat. Someone in the Android community did something pretty wild they took the software from a Samsung Galaxy S23 Ultra and made it work on your old Redmi phone. Sounds crazy, right?
This custom ROM brings Samsung’s latest OneUI 6.1 by @Rsyd58 to your aging device and surprisingly, it actually works. Let’s talk about what it feels like, what works, what doesn’t, and whether it’s worth installing.

🌟 What’s Good
So first off, this ROM is Laggy. It’s been cleaned up a lot, meaning there’s no extra Samsung bloatware slowing it down. It’s light and it feels a lot more modern than MIUI ever did on this phone.
- Mobile data now works, so you can get online just fine without Wi-Fi.
- It runs faster than expected thanks to some under-the-hood boosts to the CPU and GPU.
- Audio bugs are fixed, and volume works like it should plus it comes with Viper4FX for better sound quality.
- It even lets you sign into your Samsung account, which most ports don’t allow.
- You don’t have to do anything crazy like repartitioning your phone just flash and go.
⚠️ What’s Not So Great (Yet)
Now, since this is a port from a completely different phone (and brand), not everything works. Here’s what’s still broken or weird:
- The fingerprint sensor isn’t reliable.
- You can’t turn on the flashlight from the quick menu, but you can use a flashlight app from the Play Store.
- The brightness slider doesn’t work, but there are workarounds using accessibility settings or root.
- Sometimes the phone aggressively closes background apps, so things might reload more often than usual.
- SIM card calls and SMS don’t work, which means no regular texting or calling. Again, social media calls are fine.
- Charging while powered off doesn’t really work right.
- And yeah, some small features are missing you’ll stumble upon them as you use it.

🤔 Is It Worth Trying?
Honestly? If you love trying new ROMs or miss that Samsung look, this is a super cool project to try out. Just don’t expect perfection.Download the latest build form here
It’s not ideal if:
- You rely on regular texting and calling.
- You need fingerprint unlock.
- You’re not comfortable dealing with minor bugs or finding workarounds.
But if you:
- Mostly use your phone over Wi-Fi,
- Make calls through WhatsApp or Telegram,
- And want a completely different, clean Samsung-like experience…
Then this ROM is a fun way to breathe new life into your old phone. It looks gorgeous, runs smoother than MIUI did, and is honestly pretty impressive for a first release.
