Since I have updated my Samsung F34 to ui 8.0 android 16, it's network settings are disturbed. 5G is not disconnecting automatically and it shows no internet after some time. I tried different apn settings, network reset, reset all settings and restarted several times. Nothing worked. Battery time has also reduced. I request Samsung to please address the issue ASAP and release a network patch as it seems its a software bug. Regards

You know, the most annoying thing is that just updating the OS of the phone, I have to spend many hours to trying to rectify it. First analyze the phone check setting, then call Jio Customer Care, then talk to/email Samsung Customer Care. I shall have to visit service centers, and I'm not sure that they can fix the bugs of the new OS. Because the unstable network problem is not continuous, many times a day, I receive many miss call alerts, and the caller complains to me, my phone is not reachable.

After updating the Samsung F34 to UI 8.0 Android 16, the network connectivity has become unstable. It displays no network signal and occasionally lacks 5G connectivity. I have to restart the phone each time. I performed a network reset and restored all settings. Nothing worked. I request Samsung to please solve the issue. This issue is affecting my job. Jio has also confirmed that it is a bug in the new update version of the phone. It can be solved only by the manufacturing company.
