Messed up light sensor

I'm on my 4th TP now, for hardware defects in the previous ones, and I don't think this one is any different.

Everything is FANTASTIC on it, Feb 22nd build date.

But I've got a major issue with the light sensor...

When it's dark, it reads 0 lumens (yay!), as brightness increases, the lumen count increases nice and smoothly, till it reads around 400 lumens...

After 400 lumens, it skips to 600, then 840, then it jumps back down to 48 lumens... and the brighter it gets after that, the lumen count actually goes DOWN, ending up at 21.

So, if I step outside into sunlight, the light sensor reports 20-30 lumens... so the phone thinks it's dark, and dims the backlight, making it impossible to see my screen.

Anyone else had this issue? I've already hard reset it.

Re: Messed up light sensor

your phone will always dim in the sunlight... theres nothing u can do to chsnge that.. until they switch to the new screen type(forget what their calling it) but phones screens will be as bright in the dark and in sunight, actually making usuable screens...

theres no prob im sure... light is light, its everywhere... so are shadows.. your screen is always gonna flucuate, no matter what u do..

Lumens is a mesaure of light intensity, and it's what the light sensor is supposed to output in. I do use Lumos to manage the backlight though, and I was using it to tell me the values.

I don't mean the screen is harder to see when it's bright... I get that much.

What's happening though, is the light sensor is giving wrong values, which dims the backlight when it's bright out, the opposite of what I want. It is still hard to see but it dimming only makes it so much harder.

I was under the impression that behavior (Dimming and Brightness) was normal behavior. Bright in the dark, dim in the light.

Re: Messed up light sensor

When phone is up to my ear, the screen turns off like it's supposed to. In darkness, my screen dims so as it doesn't hurt my eyes from the brightness. As more light is applied, it increases in intensity so as I can read it clearly(normal house lighting). NOW on the other hand, I get what the OP is saying, in sunlight my TP dims and makes it unreadable which is really annoying.
