Same camera issue still persists and not resolved...while focusing giving trouble and lot of lense shakes and rattling noise...As its not resolved in this update now its sure its faulty hardware issue face by lot of S25 Ultra users...Samsung must acknowledge and recall all such faulty devices as its very premium flagship phone

True , same issue with my ultrawide camera

[Ankitastic26]

The issue on the ultrawide camera could be related to the camera module itself rather than software. It’s recommended to visit an authorized Samsung Service Center for a proper hardware inspection you can also try performing a full factory reset after backup, as it might help if the problem is caused by a software glitch, though it’s not guaranteed to fully fix it.

Thanks for the detailed feedback. Since the focus hunting, lens shake, and rattling noise persist even after the October update, this likely points to a hardware issue with the OIS/AF module rather than software. The best next step is to visit an authorized Samsung Service Center for diagnosis and repair. If desired, back up data and try a full factory reset once to rule out any residual software conflict, but there’s no guarantee it will fix the issue.

Yep soon ill visit a service center. This has been happening on my device from like a month , seems like a hardware issue.Only issue i face is keeping the phone for service as i converted sim to esim and dont really have another phone supporting in esim so will need to activate physical sim again for a while.

[Ankitastic26]

Yeah, that sounds like the best plan. Since it’s been happening for about a month, a service center check should help confirm if it’s a hardware issue. Totally get the hassle with switching from eSIM to physical SIM just for that.

New problem is Network issues now...

[Ankitastic26]

The network issue appearing after the update could be related to temporary software conflicts or carrier settings. It’s recommended to restart the device and check if the issue continues if the problem still occurs, try performing a full factory reset after backup, and if it doesn’t help, visit a nearby Samsung Service Center to get the hardware and network module checked. You can also wait for the next update, as it may include fixes that resolve this issue.
