Welcome to Android Central! Which phone? Open the Phone app, then tap Menu>Settings>Call Settings>Additional Settings, and make sure Caller ID is turned on.
Does this also happen with numbers that are in your contacts?
hi sir / madam
My watch (tic watch 2) is showing caller id ''unknown'' when ringing. This problem has occurred to other smart watches too. Earlier it was ok. This is happening after i update my phone to pie. After reading few comment regarding this matter, what i came across is this is happening because of some wearable permission missing on android os pie. plz release an update to solve this problem as soon as possible.
Thank you
