Hi, I have a Huawei P20 pro and my son removed the camera icon and could not find it. If I searched for the app it would load though. So I found this solution to find the app/icon. When you search for the app by swiping down there is a location icon to the right. Select the location icon and you will be taken to where the Icon is.  Hope it works for you.

I've lost mine too.. The solution to this is simple..Firstly, add an empty page(make sure it's empty without any widgets)..then,zoom in to the page as if you were to zoom into photos..your hidden apps will appear

Hope that it's helpfull

I got same problem today morning .. I checked my phone camera icon is gone.

Any solution?

Did u solve it ? It happened to me and I can't restore it

Hi Plamen. Are you pertaining to the camera icon you always see on the home screen? If so, simply open the app drawer, usually you just tap and hold an app icon and it'll bring a shortcut on the home screen. Please try that.
