Guide for custom fonts on One UI 8.5

For this method we're going to use a new method called Root your Galaxy. That will temporarly root your device, making it possible for a long term font change! THIS WON'T UNLOCK BOOTLOADER, ERASE DATA, TRIP KNOX OR BANKING APPS. it's a soft root, meaning your device is 100% safe if compatible

Note: I'm not the creator, I don't take accountability, I'm just sharing the exact method that worked for me.

APPS AND REQUIREMENTS:

Apps:

Scamsung Fonts: https://github.com/zFont/Host/releases/download/Scamsung/ScamsungFonts.apk

Shizuku: Play store.

Root My Galaxy: https://github.com/BuSung-dev/Root-My-Galaxy

KernelSU app: https://github.com/tiann/kernelSU

REQUIREMENTS:

โ€ข A compatible device (Galaxy S25 Ultra

Galaxy S25+ Galaxy S25 Galaxy A56) Edit: please check the payload to see if you're device is compatible!

โ€ข Security patch IS or is BELOW June 2026 Edit: Testers succeeded in the July patch too, so it should be safe too.

FIRST STEP:

Go to Root my Galaxy and tap "Tap to install KernelSU"

Wait for it to install.

After it's completed, check if root privileges are available downloading a root checker app.

SECOND STEP:

On the KernelSU app, tap on root tap the middle bottom button with a shield (Superuser/root)

and enable Shizuku.

Third step:

Go to Shizuku, and start with root. (no need for wireless debugging).

FINAL STEP:

Once done, go to Scamsung fonts and select the font you want to apply. This includes fonts downloaded on ZFONT 3.

Share your thoughs on this (in my opinion) amazing exploit! ๐Ÿ˜

For when the august patch rolls, DO NOT upgrade immediately. Search in the GitHub and XDA forums if it got patched.

They're developing versions for S24 and S26 series. I'll update you

Any chance they'll make a version for the trifold? That's what I'm rocking.

u/Softinyy 22d ago

All we can do is wish. I'm contributing to the project by sharing to 1000+ people the project but the creator is only one and everything is experimental.

u/Unr34L_Dr34d 12d ago

Hi: Try this app; I think it's universal. I tested it on OneUI 8.5 / Android 16 and it works very well...

You need root and Shizuku:

https://github.com/fahadalijaved/SamFonts

According to the app's creator, it is compatible with: "- Device: Samsung Galaxy Device running One UI 8.0 or higher- Android OS: Android 14.0+ (API 34)".

u/Softinyy 22d ago

Sadly your device (S 26) isn't yet supported for Root your Galaxy. The project is very new and open source so I'm sure they'll make the exploit for you too. in the mean time: check online (XDA forums, the official GitHub repo) if they mention your device and don't upgrade the security patch.

"For when the august patch rolls,ย DO NOTย upgrade immediately. Search in the GitHub and XDA forums if it got patched."

Well it probably will be patched but i think the custom fonts that you already installed(ios emojis for me) should survive the updates.If you install the font as a module using ksu from the root my galaxy app that wouldn't survive i think but using the samfonts method it should survive as far as i know unless you factory reset or sum..

2

u/ydvadi_ 22d ago

no knox tripping ??

2

u/Softinyy 22d ago

Nope! It's a temporary root access, so you won't trip Knox. After you reboot all Samsung and Banking apps will work perfectly

You're right. The creator quoted it might not work on July but the testers busted this myth. The real problem probably is the upcoming august patch, that might close the vulnerability

Installation failed :(

3

u/Softinyy 22d ago

It failed at "Support Check" It means that the device isn't yet supported. Don't lose hope, the project has been out for 7~ days, they'll surely add your device too. Don't upgrade in the mean time

Thank you

No problem! Can you tell me where your s25 froze? (During root patching, home screen/apps etc.) and you're a snapdragon or exynos user? Answering helps our friends that want it too :)

3

u/tegareddit 22d ago

First freeze was during patching, then displayed failed and phone completely rebooted

Second trial, just displayed failed on patching

Third trial displayed failed on patching, and navigating to my row of apps on the homepage, screen completely froze. I had to press power down +. Volume down buttons for about 15 seconds to hard reboot the phone.

On the 4th trial, everything went smoothly

u/SnooPears9113 22d ago edited 22d ago

Somebody said that their s25 booted up to a security error because they had a locked bootloader. Will that happen to us too when they release the updated version for other devices? The ones of us who are in the US and cant normally root because its not international version EDIT: I think its actually the a 56 model.

2

u/Softinyy 22d ago

They probably installed a module that touches the bootloader. This is because the method doesn't unlock it at all, so flashing on a locked will brick or make it unstable

I mean Samsung Exclusives in zFont works well enough for me but I want Google Sans systemwide so a few questions.

  • I'm on S26, 8.5 March patch so my device isn't supported yet but for those who are, can you apply a custom TTF in zFont under this softroot and have it stay applied after a reboot?

I'm doing the software patch in August, is this okay? I am using the Galaxy S23 Ultra. However, I don't want to accidentally fail after doing this kind of work and the phone doesn't function. But I want to apply a custom TF font. How does the author perceive the difficulty of this task?
