Did anyone notice that during the call, the screen isn't actually turned off, the backlight is still on, it just shows blank screen. You can see this if you are in a dark ambient because of the backlight bleed on the screen.
So, while you are talking, you will lose battery charge on call and on screen backlight. I don't think it is an economical way of spending battery juice.
So actually the screen is on the whole time during the call, you just can't see it because there is nothing showing on the screen...
Or is this just my device?
X10 2.1 nordic.
I noticed that, anyway during a call, it obviously drains the battery even though the screen switched off & the use of the Proximity sensor is to switch off the screen during a call to prevent the screen from touching than the economizing the battery
I noticed a big improvement of the battery with the 2.1 Update.
I've noticed it too, I think this would waste more battery? or is it the opposite?
Of course it uses more battery power. I can't rememeber if the same situation is in 1.6. Can anyone check?
It does use current, but i think its a minor amount. The reason why they leave it active but black for example, is that if you need to quickly access the dial pad you can do that, without waiting for a second or two for the screen to power on.
I recall back on 1.6 at times it felt like eternity that it would take to bring up the dial pad during calls. I'm not sure but check to see if the screen does in fact turn off completely after a certain duration, since that would be ok.
Nope, it doesn't turn off and I wouldn't say it's a minor amount of power, because the screen is one of the most power hungry components in our phones. So if you are in a call for say 30 mins just think how much battery that would suck out. And for me, for no good reason, when I'm on the phone I don't need the screen, that is why the proximity sensor exists, to turn the screen on and off
I understand, but you have to understand how the lcd works. Producing colours or tints cause the device to use more power. The brighter the colour the more power. Since white is the brightest tint or colour, whichever you prefer, black being the opposite would use the least amount of power for the screen being on. Unless this is a type of lcd matrix that uses most power with black I read about that before somewhere. But I highly doubt SE would do that. But considering its a concern of yours there might be an dialer app that negates this hmm.
At the Sony Ericssons products Blog there was a video about the new features at 2.1
It tells also that you could press the Power-Button to turn off the light during calls.
I´ve not testet this yet, maybe of you could test this. ;-)

It does not take a second or 2 for the screen to come back on. Just test it yourself by pressing the power button, it comes on within 1 second. On a side note, in the 1.6 days the screen would stay on completely and if you press the power button it hangs up. That was a terrible implementation.

Im on 2.1, cant check it anymore. It was rather sluggish for me on 1.6. The difference may be that I had pictures for all my contacts. I like it just fine.
Yes, you can turn the screen completely off by pressing power button, I've just tried. I don't understand why do I have to do it with my finger when I have proximity sensor that works just fine when it wakes up the screen from complete power off when I move it from my face. Seems like a bug to me.
LCD screen consumes the same amount of power no matter what image it is showing, black or white, so as far as I'm concerned showing black screen during a call does absolutely nothing for me, especially not for my battery. This is so trivial that I can't believe they missed it. Or maybe some SE engineer thought X10 has AMOLED screen so it doesn't consume power when it's displaying black...
Personally, I prefer the screen turn off compared to the screen lock in 1.6 as I had a hard time unlocking the screen lock when you need to use the dial pad when on the phone.
So when you are on the phone, the screen turns off and when you move your phone away from the ear, the screen turns on.

You are 100% correct, my mistake, lcds do use the same amount of power due to the backlight. I was just on the phone for 50 minutes and my battery went down by 5%, so i think its not bad at all. I was even on wcdma/gsm.
Drop SE an email to inquire on it maybe?
Well, maybe I'm exaggerating, but this kind of screen backlight beahaviour just isn't logical to me. You say you lost 5% on 50 min call? Hmm, that really seems low...
Where can I send inquiry to SE?
i have the same problem guys.....any solution yet?
working on a more accurate solution atm.
Anyone experiencing random screen brightness?
Every once on a while when I turn the screen on I notice the screen is brighter (kind of washed out looking). If I put the screen to sleep and then turn it back on it goes back to normal. Don't know if it's a defect or what. Just wondering if anyone else had noticed something similar. (Smart Actions are not on so I don't think it's that)

I've had my Razr for about 16 days now. So far, this has happened once. I always use the phone with ambient light sensor off, and brightness set to lowest setting, but one night when I turned I the screen it looked like it was on the highest brightness setting, and the screen had weird colors. The reds had turned to purples, if I remember correctly. I turned the screen off then on, and that seemed to fix the washed out colors, but not the excessive brightness. At some point later that night, the brightness fixed itself without intervention.
yeah I get that too, been getting it probably once a day for the last week or so. I have mine on auto brightness and I can get it sitting in the same chair in the same light conditions a couple of minutes apart from no issue.
Switch on from lockscreen and the brightness is through the roof, hit power button to suspend and its fine when I go to open.
Yesterday I had it the other way, was really dark at first
I have the AT&T H900 V10 and I can't figure out how to keep the second screen from dimming when the main screen is off. It's so dim that I can't see it unless it's directory in front of my face, and no buttons seem to brighten it without during the main screen on. Is this something that can be changed? I'm not worried about battery life since it stays plugged in 99% of the time.
Same

So far there doesnt seem to be any way to control this, other than covering the light sensor until the second screen goes off, then letting it come back on at greater brightness for 3 seconds or so until it dims again. Maybe LG is trying to make sure it doesn't drain battery but maybe they will adjust it with updates or give us control over it.
It pretty much makes the second screen useless as I can't see any notification without turning on the main screen.... and no LED light so this kind of makes me want to rage.
Also, always on display turns completely off.
Not sure what's going on here, but it's extremely annoying. If I'm outside at night or in a dark room or area my phone thinks it's in my pocket so the fingerprint sensor, tap to wake, and always on display don't work. I have to press the power button extremely hard to get it to turn on.
Also, not sure if related but when I make a phone call, as soon as I dial the number my screen will turn off completely before I even bring the phone up to my ear.
Any ideas?
Make sure there's nothing in front of the proximity sensor. When that is triggered and it's dark, it disables the fingerprint reader and always on display. I use a Life proof case and when I had a screen protector on with that, it caused issues.
Definitely nothing on it. Not using a case or screen protector.

Download a sensor test app, there are many of them on the play store, check the proximity sensor with one of that apps, if it doesn't work then your g5 is faulty
Sent from my LG G5 using XDA Labs
Also noticed when I cover up the sensor my brightness immediately jumps to 0%. It's no longer a slow and steady drop down to 0, it just immediately goes to 0. Like and on/off switch
Just downloaded a lightand proximity sensor test and it seems to work perfect. So I'm not sure what's up.
OK this is weird,there must be a setting I messed up. My auto brightness jumps from 0% to 51% to 100% depending on the lighting I'm in. Nothing in between and no more smooth transitions.
Looks like my proximity sensor is dead. Tested it through and app and it says "near" and never changes.
I'm pretty sure my S7e had the option to turn the screen completely off when in a pocket or face down, even when AOD was turned on. I can't find any way to do that on the S9. Even on auto brightness it stays on, very dimly. On manual brightness, it stays on at whatever brightness you've set. What's the point of having AOD use even a little bit of battery if you can't see the display at all?
Anyone found a way to shut AOD off in these circumstances?

Thanks, but that's not it. I do have that turned on. It's not that AOD turns off but comes back on because of touches. Unlike the S7, it never turns off, even in a pocket or screen down.
Is this just a rant? Cause it seems like you've answered your own question.
Actually, it does turn off completely. If you cover the proximity sensor for around 30 seconds, the AOD turns off completely.
Same as the S7, same as the S8.

I've been trying to solve this as well. It seems some models have different wording in the block touches option. My tmobile device says something like prevent touches while in a dark place, pocket. I've been told the wording for that option on other models is more like disable screen in dark places, pockets. I hope it gets changed in an update.

Actually it does not. What's weird is I swear it did when I first got the phone but it seems like an update broke it or something because it no longer does it.
Really hope a future update brings it back because I haven't found any settings that enable it.
Anyone figure this out?

What I've figured out is that it works 100% on my S9+.
And my wife's S9+.
And my daughter's S9+.
And my other daughter's S9+.
You may wish to review the settings on your device again.
I hope you find the missing configuration, because I can understand the frustration when something appears to not work as it should.
Having had a number of S7 phones that featured a stuck rotation-lock due to a borked accelerometer, and "glowing" screens while turned off due to bad display drivers, I would not discount the possibility that your device could be defective, if you have turned on the appropriate feature-set and the AOD still does not turn off when the proximity sensors are covered.

Nope. If I put it face down on a table or desk in a completely dark room, I can see the light from the screen reflecting off the surface. (My case lifts the screen slightly off the table.) And if I take it out of my pocket, I can see the AOD is very dim immediately after coming out, and then brightens after a split second.

Have you checked it in a totally dark room (say, a bathroom, at night, with the shade closed and the door closed)? Because that's when it becomes clear the screen is just very dim, not off. Also, if you set manual brightness on the AOD, instead of auto, it's very obvious that it stays on even when the phone is face down.
What do you consider the "appropriate feature set," because I've looked all through the settings and there is no setting for turning the screen off when in a pocket or face down.

I think I see where at least some of the misunderstanding is now.
What you describe is expected behavior in the dark/low-light scenario.
Note that the AOD turns off (if you've enabled "Block accidental touches" in the display settings) only if the >proximity< sensor detects that the phone is, well, in proximity to something - such as when it is face-down or in a pocket.
If not in proximity to something, what can be expected is that the illumination sensor will simply adjust the AOD brightness (if in the automatic mode) in response to the ambient light it detects - bright in bright light, and dim in low or no light. Just as you've described your experience.
Again, if your "Block accidental touches" feature is on, and the AOD isn't turning off when it is in proximity to an object (in a pocket, face-down, etc.) you may have a defect.

I don't have block accidental touches on but it does turn off when it's in my pocket or faced down. It might be just your device. It always turns off for me when it should.

Interesting. I was always under the belief that the setting was required in order to assure AOD would turn off in those situations.
Turns out, it does work regardless of the state of that feature!
I still think that having that turned on just makes sense for those times when it is in a pocket, but you are correct in that it does not preclude the AOD turn-off feature.

I have that setting on but it still won't turn off AOD in my pocket. I was worried my proximity sensor was defective so I tested it but it appears to be working fine.
What model/carrier do you guys have. I have the attached branded snapdragon model. Like I said before it used to work but now it doesn't. Not sure if it coincides with an update or not

You could always factory-reset the device and see if the functionality returns.
With an SD card and a SmartSwitch backup, it's not that painful to reset the phone and get it back to (more or less) the configuration you have right now.
After a reset, I'd probably test it >before< restoring the SmartSwitch backup - just to confirm that it isn't some app that is breaking the AOD turn-off deal.
Best of luck with this.
