In my internship I have never put my mobile phone outside the bag on my table because otherwise with every notification I would look on it and get interrupted in my concentration. However how could designer of those notifications minimize the interruption? It’s important that users always can change notifications in the app’s settings. You should personalize them: show the apps icon with an image and show the time when it was sent. Categorize the notifications and let the user decide which one are important and which one not. When the text is very long you should just show the first part of it.

I think it’s important for me that you see the beginning of the text. Like that I can decide wether it is an important message or if I could answer later. They shouldn’t get the user’s attention so much otherwise you always interrupt them in their concentration. Most of them look on their phone unconscious. You should think about a time where you check your messages again: “ after that project I check my messages but not during working on it.“
