    Hi awesome peeps,

    Wondering if anyone noticed ambient light sensor/automatic screen brightness issues? My first Blu HD wouldn't change screen brightness (no, not in battery saver mode) but the manual brightness setting does work. I brought it into the MS store where I got it from and the "tech" guy didn't even know what a light ambient sensor is ... long story short, we tried another Blu HD phone there and noticed it did the same. The tech called Blu and because Blu is charging for shipping to and from their service center, he gave me a new one off the shelf as a replacement.

    I expected it to behave the same and not have auto brightness (i.e. only manual brightness but advertised with ambient light sensor), so I didn't even check until after installing recent 8.1 update 1. Now I notice it has a funny behaviour. When I turn on the screen from sleep, it will read the current light level so when the screen actually comes on, the brightness level is correct. When I go to a brighter/dimmer location, the screen will change accordingly, brighter or dimmer... but only one time. Going to a brighter/dimmer location won't make a difference anymore once a change has occurred.... unless I turn off the screen and turn it back on again. I've used quite a few phones and have never seen one that would only change brightness one time per screen wake. What the heck.

    Also reached out to Blu and waiting for a response now.

    Hmm. Surprised no one else has had this issue, since 3 out of 3 devices I tested behave with this problem. Oh well.

    Anyway, Blu replied:

    "We are aware of the issue and our technicians are working towards an update to correct the issue. We appreciate your patience."

    Hope a fix is coming out soon.

    I haven't tested it with the recent new firmware yet, but with the old one, it would brighten the screen but after you point it at something bright, it won't dim again when you go into a dark room. Like I reported, it only changes screen brightness once per phone wake.

    Same issue here. When out in the sun I need to turn the brightness to high, manually. Auto does not work.

    I sent a support request/bug report to BLU detailing this issue. I was very clear mentioning point by point what the problem was. (all updated, ambient light does not automatically adjust screen brightness). Their reply is disappointing. See below.

    In my report to them, I also referenced this thread to show them a few people are experiencing this.
    Their reply shows that they did not investigate this much.
