How to Fix Galaxy S26 Mobile Hotspot Not Working After Update

Galaxy S26 Mobile Hotspot Not Working After Update usually means tethering settings were reset, the mobile data connection is unstable, or the latest One UI build introduced a carrier provisioning issue.

Method 1: Confirm mobile data is working on the phone

If cellular data is down, hotspot sharing will fail too.

Turn Wi-Fi off on the Galaxy S26.
Open a website over mobile data.
If it does not load, fix the cellular issue first.

Method 2: Restart hotspot and reboot the phone

This refreshes tethering services after a bad update session.

Turn Mobile Hotspot off.
Restart the phone.
Turn hotspot back on and test again.

Method 3: Rebuild the hotspot configuration

Saved SSID, password, and band settings may have been corrupted.

Open hotspot settings.
Change the hotspot name and password.
Switch hotspot band if that option is available.

Method 4: Remove battery restrictions on hotspot-related apps

Aggressive power saving can interrupt tethering setup and sharing.

Disable Power Saving temporarily.
Keep the screen on while testing the hotspot.
Retest with the phone unlocked.

Method 5: Reset network settings

This clears broken APN, Wi-Fi, and Bluetooth settings that often affect tethering.

Go to Settings > General management > Reset.
Tap Reset network settings.
Set up hotspot again from scratch.

Method 6: Check carrier hotspot entitlement

Your plan may require tethering to be reprovisioned after an update or SIM change.

Open your carrier account app.
Confirm hotspot usage is included.
Contact support if tethering is blocked.

Method 7: Install a newer patch

Samsung or your carrier may already have a fix in the next build.

Open Settings > Software update.
Download and install any newer version.
Test hotspot again after the restart.
