Hello guys! Could someone of u help me with a question? I gave to my wife a Xiaomi Mi A2 Lite. 3 days ago she dropped into water. She put the phone into a bowl of rice and after 24 hours startup it. Well, everything works good, but the backlight is very DIM, even when she adjust the brightness bar nothing happens. But is very curious cause if I startup into Fastboot mode the backlight is very very bright like it should be, if I startup into recovery mode, is very similar, and when I startup normally the Android one logo at startup is really bright with backlight in maximum, but as soon it finish the startup the screen come back to very low backlight. Could be software damage or probably hardware damage? If backlight is very strong on startup, why isn't working after the logo? Do u think if I do the Hard reset could the screenlight comeback to the normal situation?

I think it's just the glass is dirty at the ambient light sensor.

Thank u for your answer. I had thought about this ambients light sensor, but, if it was this one, when I turned the auto brightness off, should the sensor been deactivated, right?

Hmm, don't know this, test it manually with slider.
I already had tried. I don't know what's going on. The cellphone was really new... Less than 2 months.

The whole time I had my original EVO 0002 version, the backlight for the 4 round hardware buttons at the bottom of the screen, stayed lit whenever my screen was on, period. Now that I had to get a 0003 replacement device, it seems like either HTC changed something or my replacement is borked. Now the 4 buttons seem to light sometimes and sometimes not. I can't tell if there is some kind of deliberate pattern, or if it is tied to the sensor for adjusting the display brightness, or if its just broke. How is the backlight supposed to work on this version?
Thanks
my 0003 does the same thing, wish I could just keep them off.
Interesting, I noticed the other day that mine would light up even with then screen off so i wiped cache and dalvik. This fixed that issue but from your post I noticed mine does the same thing... Are you running a custom kernel?
Edit: I went into a dark room and turned my screen on probably 20+ times and they lit up every time. So my guess would be that it has to do with the brightness sensor. When its bright in the room its probably set up to where they are not supposed to come on.
Yes its designed that way.. it only lights up indoors or when its not really that bright ... pretty damn cool huh? I think htc was trying anything to increase battery life..

Did you mean it only lights up indoors when it isn't in a bright room? Because mine does not always light up indoors?!
Ok thanks everyone who resonded. I suspected that it was a new "feature" introduced on the newer hardware version, meant to extend battery by only lighting the buttons when it was dark for whatever reason. Makes sense since the nice silver etching for the circle and icons makes using them simple in even low lighting. Its just annoying as heck watching them turn on and off randomly, when you are so used to them just being lit all of the time you are using the phone, like I am from my original unit.
Now I know my refurb isn't just screwy.
Hi all
Just got my new unlocked One X today, but already I have problems with the software, Back, Home and Apps buttons lights going out out.
They seem to come on and off when ever holding the handset at a strange angle or position. Is this normal or is there a setting that needs to be changed to stop this from happening, or more likely the handset has a fault.

I am not sure about this but I never noticed this while on 1.26. Someone "complained" about it and I noticed this on 1.28. The 3 button led light only come on at night. So they are now sensitive to ambient light. Try to cover the front top part and you will see them come on. Remove your hands the led's go off.
But as said, I am not sure if it was like this when I was on 1.26. Didn't take any notice of that.

Haha... buttons illuminate at low light/night time conditions, no fault.
u can adjust the sensitivity with a rooted device but that is another story for another day.
Wow, I feel so thick.
I was so close to packing up the handset and sending it back because I thought it was faulty.
Cheers for the help.

I was thinking the same thing. They are defo run on light sensor but it is too aggressive. If there is a small lamp on in a normal size bedroom they go out yet the light is no where near enough bright enough to see the buttons with out their lights on. Its making me have to send the phone back. Oh well SIII here I come..Pity! :-(
Soo close...

I have just had similar problem except my light stayed on, if I held it, the software buttons would flicker on and off and if I tilted it backwards would dim, even stayed on when phone was turned off. HTC tech said that it was faulty and the phone is being replaced.

I´m also ready for that story!
Does anyone know how that works. I would prefer that they always stay enlighted, when screen is turned on. I´m using Viper X maybe that can help...

For Venom-ROM I found it searching the Tweaks. Go to "Button" and set "Capacitive Backlight" to "Never " and they´re always on, when your screen is on. There are some 9 differeint steps to control the sensitivity.

Hey Guys,
got my new Note II yesterday, but already having 2 problems.
The biggest is the light sensor; the Screen keeps adjusting it's Brightness like hell.
Read out the Sensor data, which is going from 0 to 13 lux when I cover the Sensor with my hand.
Do you experience the same?
Also my USB wire plug is very loose. Also normal?
try turning off auto brightness...
and yes USB wire IS a bit loose

Well, just bought it brand new, I think this shouldn't be on a 600€ device
Does your Light Sensor Value also jump around in same light conditions?
Low-Light mine goes from 0-28, normal it goes from 400~ to 80.000 sometimes, which results in frequent readjustment in brightness.
Thats very irritating for me, cause I use it everytime
Would be nice if someone could give me his values/behavior of the sensor with AndroSensor or so.
Will return this device then

I just got my GT-N7100 and am having the same problems. Very irritating. Need this to work for better battery life. Tried a program from Play Store called Lux, but it works the same, maybe a little better. But Lux is showing the sensor readings varying all the time even when the ambient light hasn't changed at all, thus the brightness fluctuations. I am rooted, but on Stock ROM. Wonder if a custom ROM would fix it, or if it's a defective sensor.
Anyone else experiencing this?

The default auto-brightness should not be updating so fast that it flickers You might want to get it checked out. Or if you use a 3rd party app, reduce the time interval of the update.
And do note, there is a difference say, with your back towards the sun, you face the phone towards you, or towards the floor. So when you are on the move, expect values to change.
Stock auto brightness is woeful in my opinion. It was the same one my Gnex so I have used Luxbon both with good results. Takes a bit of tweaking but brilliant when set up.

I'm not an expert at light sensors, but look at this:

I'm moving phone, holding camera still.
It looks like light sensor problem on galaxy note 2.
Can you check yours GN2?
Use code *#0*# and enter sensor test.

I'm not in the brightest room but I have 2 60W light bulbs above me and my sensor has 0 when the phone is towards me and 20 lux when it is towards the roof. And yes it's stable with the values.
Recently, my screen starts to have some narrow trapezoid dark marks along the left and right sides when the screen brightness drops below 40% (like 28% set by Auto Brightness). Sometimes there is also some color bleeding (from the icons and background below) at the top edge when the dark marks appear. When the brightness is 40% or above, they disappear. I suspect it has something to do with the PWM that controls the brightness. Does anyone has similar experience and any suggested ways to fix it? I am considering to send it to LG warranty repair. Thanks.
It's unrooted and on stock ROM, right ?
you could try a factory reset and see if it changes anything ...
Was the phone particularly hot at the point in time ?
Are you gaming ... like a lot ?

It is a T-Mobile, so no root and stock rom.
I may try a factory reset and see how it goes.
No, it was not very hot when it happened. It was at normal operating temperature.
No gaming. I don't even have any games installed. Those are not burn-in, as they are not in a fixed position. If I adjust the brightness, the dark marks will shift their location with the brightness %, so I suspect it is the PWM that causes it.

Could very well be, I'm however also thinking about SoC and Die (https://en.wikipedia.org/wiki/Die_(integrated_circuit)) issues [hardware defect]

I agree with you. I did a factory reset and the issue remains, so it is likely hardware failure. I sent it to LG Warranty repair and see what they say.
LG diagnostic finding is "Display screen is discolored", so it appears to be the OLED screen that is defective and is covered by warranty. The "LCD (Main,Sub)" is replaced. I didn't know there is a "sub" LCD.
I received my phone back, and it seems I get a new phone. It is wrapped in plastic film. Thumbs up for LG warranty.
My proximity sensor is pulsating not while on call but while screen is off and in good light conditions. When ambience is dimmed, it stops. Why is it doing this, any fix? Using dome glass.
Weird, but maybe somehow the glue and glass are indeed interacting with the sensor under certain conditions, I was wondering if with this new under display sensor wouldnt be this kind of issues, reading about your case, then I will not use any
Any other insight or possible solution?
I need to make a correction to my question. This behaviour happens when AOD is on and light is good. Funny enough I don't see it on call. But screen turns off just fine on call.
Same here. Even with AOD off. Seems to turn on randomly and flicker. When I wave in front of it, then it stops.
If I turn off the AOD, it stops doing this.
I also have this..sometimes it keeps flickering even after I have unlocked the screen. If I put my finger over it then it goes
I had to turn off tap to wake as the phone kept coming on in my pocket despite the phone being faced towards my leg, to me the proximity sensor in the 10+ is just wrong.
I turned off adaptive AOD brightness and it stopped doing this.
Interesting. I don't see this behavior.
With AOC on a slightly than 1% per hrs battery usage seems to be nominal operation.
This circuit uses little current I suspect anyway.
Unless it's using more battery than I stated it doesn't matter.
It wouldn't harm the OLED... cool find.
