Signal Issue S25 Ultra

[Naveed_Kamran]

Facing issue regarding Sim signals. Using Jazz sim in my office and even home signal bar shows only 1 or 2 signal bars. 

When same sim i switched backed to my old fone of Oppo all signals are good with 4bars.

I have also change network setting to 4g to 3g. 2g. But Same

Try resetting your network settings, or it might be a bug. Wait for an update; it'll be fixed then.

It is quite normal for samsung phones to show less signals but the network quality will be same.

Hahahah i have been using samsung since 2021 yes it has bad signal reception due to designs and poor antenna fittings and sorry to say u r wrong that signal show week but quality is good it,s totally wrong .on 1 or 2 bar the data doesn,t work and calls drop so when i use same sim in same location in xiaomi all works good .just with samsung for software otherwise it,s quality going down

Don't compare signal bars. Compare Signal strength in dB.

You can find actual signal strength through 'Settings > About Phone > Status Information > Sim Card Status > Signal Strength "

This valve is realtime signal strength valve. Compare this value for Samsung and Oppo. It will clear whether you have signal issues or not.

(Lower Value is better, higher value means poor signal reception, at -120dB signal is almost 0)

Ok. I will share a screenshot with same network sim. On 2 different devices. Like samsung and oppo

Signal bar indicators vary across manufacturers. Signal strength is typically measured in dBm within device settings. Each company employs its own standards; for example, Samsung may display only two bars at -100 dBm, while Oppo or other brands might show three or four. Therefore, a full signal bar display on a Samsung device, coupled with an "emergency calls only" network status, indicates a network problem. However, two or three bars with a functioning 4G data connection generally signifies acceptable network performance.
