Before this problem happen I get in to recovery mode try to wipe cache but i miss press and i selected "apply update from adb"

So anyone have a solution for my problem. please I really need your help!

LP 5.1 AD notifications will not blink forever ?

Hey guys,

Since upgrading to LP 5.1 I've been not that happy really. Some minor bugs, a lot of RAM consumed by the system and, of course, the lack of the wave to wake option.

Now, I have just discovered another "change" (a bit late, I know) in the Active display behavior. When I had KK and I had AD notifications blinking, they will blink forever (even tho, they started to blink with more gap between as time passed)... Now I noticed that AD notifications with LP 5.1 blinks for a limited period of time (don't know which one yet), and then stops doing it, leaving the screen totally black and without knowin I have a notif pending unless I take my phone.

Anyone noticed this change of behavior too ?
