    Don't pay attention to my previous post :

    Long press on the phone app -> App info -> Storage -> Clear data and cache

    Seems like a common problem.
    (1) Some have done a factory reset - I did NOT try this.
    (2) Others have had sucess with the solution above -- not me...
    (3) In my case I was using my network provider's calling-over-wifi app (because reception is not perfect everywhere), and I had inadvertently told Android to restrict its notification access too much (because it had an annoying notification when it wasn't being used), and so it did not have access to the screen. {So it was my fault!}

    Mainly, check the notification settings for any App that might receive the call, not just the Phone app itself.

    I figured it out... it was the phone cover making the phone think its in pocket mode... had to remove the protective plastic cover over the screen to make it work

    This worked for me (on Oneplus 5T) in combination with resetting all app settings (settings>system>reset options>reset app preferences). Not sure which of the 2 was the actual solution. Had this issue since new Pie Android upgrade (received incoming calls and vibration but screen stayed black). I did not have the option available as given earlier: "Behaviour -> Select "Make sound and pop up on screen" for me that setting could not be changed (was greyed out). Thanks!

    Could you please tell me how the screen cover related to pocket mode.
    Because I even have the same issue you have faced when trying to change the behaviour.
    And changing that solved your problem? Because i am facing a very rare case in my OnePlus 6T

    Was facing the exact same issue on my OP 3 after the pie update. During an incoming call, the phone would vibrate / ring but never shows the caller screen. It was as if phone is in idle and if picked up it will show the ambient clock, even if you unlock nothing shows and the phone simply keeps on ringing. And only after a good 10-15 secs it shows the caller screen.
    First tried this and it dint work,
    Long Press on Phone App > App Info > Notifications > Incoming Call > Behavior was 'Pop on screen' but that cannot be modified
    And this worked,
    Long Press on Phone App > App Info > Notifications > Default > Behavior > Make sound and pop up on screen
    This solution also worked on Colleague's OP 7, so safe to say it may very well work on OP 5, OP 6 on Pie as well.
    Hope this helps

    Hello Praveen thanks for your solution.
    Actually in my OP 6T i am facing this problem from the month i have purchased it(Around 6 months). So I have tried all the solutions provided here. But none of them are working fine.
    So a week back i have tried the same which you have suggested, after resetting all my app preferences. But i am still facing this issue.
    Here i have noticed one more thing. Whenever the call comes and its not displaying open the phone app and you will see the call details/menu in notification screen.
    For me it looks like OP optimisation part is the reason causing this problem (First thing came in to my mind) .
    Hope you guys check it and put your comments.

    None of the above solutions worked for me.
    What worked for me was setting the 'Default Phone App' *** your 'Phone App'.

    After Phone->App Info->Default App option: You will either see a yes or a no. If it's not the default app, set it as default one and it will work. I think it has something to do with preferences on a system level.

    Even I'm facing the same issue. display doesn't show up for 10secs or more and i have to short press the power on off button, and after 5-10secs it shows the caller ID. till then i can hear only the incoming tone.. I'm in a place where there is no OnePlus store too.
    request OnePlus to fix this bug. is frustrating
