I like the stock text messaging app but it's kinda slow, so been using Textra which is my favorite SMS app. Problem is, even though LED blinking is enabled under Textra's settings, when I receive a new text/mms message the LED is not blinking. At all. I seriously watched it for probably 2 minutes just looking for it to do something and just... nothing. 
Anybody figure out how to get this working? Does it work on other SMS apps?
