Hi ajgopal

Hmm. I think it has something to do between the K8 Note and that non-smartphone. Have you checked if you're experiencing the this behavior on other non-smartphone? I will ask around what else to try. Please let me know if you can duplicate this behavior on other non-smartphone. Thanks.

No the issue is not duplicated b/w other lenovo smart phone and other non smart phone with all types of sim.

Yes this issue happens only b/w lenovo k8 note and non-smart phone with jio sim only.

Please get me the phone dailer app updates on lenovo k8 note phone for exact solution.

Hi ajgopal

I would suggest contacting JIO since it's only happening with JIO. We can try to ask around, but the phone will no longer receive any updates. At this point, we can only report it on our end.

I have already used Truecaller app from Google Play Store where workaround does not work. If Truecaller app is used then it is shown as Hidden number instead of unknown.

Workaround even does not work with techgigs truecaller premium apk apps in lenovo k8 note.

Hi ajgopal

I have raised this. Let's see if we can get future assistance. I will let you know if I have an update for you. Thanks.
