message on screen

[Android Central Question]

When i get a text message on my google pixel , it only stays on the screen for 2 seconds, so if im out the van for a min or so , i dont know i had a message unless i have to tap the screen , how can i get the message to stay on the screen permanent until i decided to open it, Also when i does appear and i get a chance to see it , it is very dark and not very easy to read at a glance ...
Thank you
