For Android users the simplest method is to select Settings->My Device->LED indicator and untick Notification. On the most recent Android update you can do cleverer options, but this will work.
For Blackberry users the suggested route is Profiles->Select the active profile and Edit->Select Messages>Turn off the repeat LED notification
The best route for most phones is to type into Google “Turn off LED notification on [your phone]….” .
Why have we suddenly delved into phone advice? Because it is very difficult to be attentive to the current person in front of you, focus on the current task, set aside your phone during family time and so on when an electronic device is saying “read me, read me” in the corner of your eye. As managers and leaders we have to be attentive. We should all be working on difficult important stuff and we will find that difficult if we are endlessly distracted.
The flashing notification light is telling you nothing – nothing at all.
Let’s assume you receive 100 emails per day (I know you receive more, but let’s go with this) over the course of a 10 hour day. You are receiving 10 emails an hour or one every 6 minutes. So, what is that flashing red light telling you? There is always something unread. There is always something in your inbox. Turn it off and take control of when you review email (and texts).
Be attentive to the person or task at hand.
