I recently started using an Oppo A77 phone and have no experience with ColorOs. All I am trying to do is to be able to display a preview (sender/subject/body/something) show up on my notification window where Gmails notifications come up. There is no option to select preview messages in the notifications settings. This is my notification setting for gmail:

and this is how my gmail notifications come up:

How do I get a preview of my gmail notifications on an oppo A77 ?

This is the exact question asked on other sites and no one seems to know the answer :

I think I found the answer. I was also looking for the answer because I also wanted to expand my notifications and I tried it and it works.

Deactivate applock for wtsap etc.. And you will get the preview... Confirmed ..

Goto "settings" "app encryption" and "unlock" the apps you want to preview.

    What makes you assume OP uses that applock app? I see no indications for this.
