No call types or message alerts are on the screen. No incoming alert lights up on the locked screen.
My phone is the new NOKIA 5 ds.
What can I do?
You need an app to provide this functionality on stock Android. I use Glimpse: https://play.google.com/store/apps/details?id=de.nullgrad.glimpse
Thank you very much. It is unbelievable that a new phone does not display the messages, e mails, etc. with a light picture, when the screen is closed.
