S25 ultra network problem after update ui8

[sunnyHanny]

Hi everyone,

After updating my Galaxy S25 Ultra to the latest One UI 8 version, I’ve been facing network problems. The signal keeps dropping frequently, and sometimes the mobile data doesn’t connect properly even when the signal bars are full.

Before the update, everything was working fine — no network or data issues. I’ve already tried restarting, resetting network settings, and even changing the SIM slot, but the problem still exists.

Is anyone else facing this issue after the One UI 8 update?

Any official fix or patch expected soon?

Thanks in advance for any help!

I have updated the beta version and I am not facing any issues. Try contacting service center . They might have some updates

Yeah, I'm having the same problem on my S24 Ultra. I switched the SIMs, and it works fine on my OnePlus. This started after the UI8 update.
