Sergio Sonego , via OnePlus 7T , Nov 11, 2019 : I was looking for posts about this and many are old and offered no solution to the problem. The absence of led notifications is a huge let down for me. I knew this when I bought the phone, so I tested apps in my OP6 before buying (with led off) to see if there was a replacement for this function. Well, the apps worked fine in my OP6 and don't in the new OP7T. DAMN! On one side, OnePlus makes fuzz about the Zen mode, to disconnect you for a while, and on the other side they force you to pick your phone regularly to see if you are missing something (a quick look to a led was enough) . Does this make any sense?
