Truecaller not showing caller's details

[becool773]

Hi,
I have installed Truecaller in the 5t. It is not showing names etc. of unknown numbers when I receive a call, but it shows them after I end a call. I have tried playing with the settings of Truecaller but can't seem to find anything. Any help?
Thanks

Looks like you need to have a Wifi connection, or at least 3G.
For Oreo some other settings is needed.
Have a look on this link https://support.truecaller.com/hc/en-us/articles/212028169-Live-Caller-ID-is-not-working

Also on some Samsung phones there are some settings that may block it
