Icon missing

[AC Question]

Gmail is installed on my phone but the icon is missing. It is not listed in the alphabetical listing of apps but when I do a search I find it and I can open it. I also have the same problem with Google Tracks.
I don't want to do a search every time I want to open the app.
Any ideas?
My phone is oppo f1s

Is there a folder called Google on there?

Google Tracks was shut down last year: Google will shut down My Tracks on April 30 | Android Central

Functionality was incorporated into Google Fit.

As for locating your email app, I'm with @chanchan05 some devices have a folder in the full app list that contains all the Google apps, I believe my Samsung tablet is/was this way.
