Always on display - notification numbers?

[Android Central Question]

Hi all,

I have the Samsung A3 2017. I just have a quick question regarding the always on display, is there a way of turning on notification numbers for it?

For example if I get a text from person A and don't look at it straight away, I get a symbol come up on the always on display. But if I get another text from person B, there is no change to the symbol, so I don't necessarily know I've received another text.

This also goes for Whatsapp and all other apps.

Is there a way to turn this on?

Thanks!
