There *IS* a "proximity sensor & light" on the DX. It's what will quickly light up when you put the phone close to your face/ear for a phone call -- it results in the DIALING PAD & Screen to go Blank when you're on a call, unless you use the Speaker. You can also see it quickly flash when you power P your phone (in a dark place) ... it is very small and located juet left of the ear speaker .. it IS different in location and size to the normal LED light(s) that light up for notifications however.
That is usually a notifcation lamp, it blinks when you have a message or something on status bar that hasnt been acknowledge, try pulling your top status bar down and see if any missed notifications are listed therem if so click them and respond as need and the light should stop.
I have the same issue.
When I used my original DROID, the blue light was a Facebook notification. On the X2 when I get the blue light, I check Facebook and there is nothing. I'm at a loss as to why this light flashes. I hope someone can figure it out.
You need to check the Settings on your various Apps ... like your text app, Facebook, Twitter, Email, etc... Many of them have a specific LED light color that you can set ... so that a specific color is associated with a specific App. e.g., on mine, I have a green light for Email and a Blue Light for text msgs. Good luck.
So, you're saying that when the flashing blue LED light comes on, there is nothing in your STATUS bar and it just eventually goes out? How often does it happen? If somewhat happens often enough (like every hour or so), you can run in SAFE MODE for a period of time just to rule out any rogue 3rd party apps. just a thought. But strange indeed. Also, have you tried a CLEAR CACHE procedure? Fixes many ills associated with the GB update.
Correct, nothing in the status bar. Email notifications and texts come up with a green light (double checked today, green). No clue what blue is. It happens like once a week.
I haven't cleared the cache but I guess i'll look into that later.
