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.
How do I allow the screen to remain on during a charge?
I use my phone for music in my car, but find it irratating when I have to constantly turn the screen on and enter my unlock pattern.
On other android devices there is the option to Leave the screen on during charging under Applications > Development.
Any Ideas on the Galaxy S2?
Kind Regards

I'm pretty sure they took this out because you'd get burn-in with SAMOLED screens...
Even if you do figure out a way of how to do this I would advise you not to. The screen can get pretty bad "burn in" pretty quickly, as I had found out with my old galaxy s.
I'm having the opposite problem the screen will remain on while charging. Cannot find a setting , four example woke this morning and left the phone in the charger returned a hour latter and the screen was still on, dimmed down but still ON.
is there a way to fix this, I'm worried about burning the screen early
This is a standard android feature that was originally found in the SGS but removed in the froyo firmware upgrade, there was no reason given but it was speculated this was to minimise screen burn.
There are a number of widgets on the android market that does the same, Widgetroid is one from the top of my head but even that's a bit of an overkill. Just install to restore the functionality.
Hi folks
I have just changed the mainboard from my TF201 with one i bought off ebay (TF201 with badly damaged screen).
Now i have a heavily flickering, dark screen. The flicker goes evenly over the whole image, that turns on and off, so i assume it's the backlight. The brightness resembles the lowest setting. The screen flicker frequency is dependent on the brightness setting. Lowest Setting: about 4 on-off-cycles per second. Super IPS+ Setting: i would say about 25/second (still a noticable flicker, but the tablet is usable).
When there is just little stuff to draw on the screen (like at the "power down?" message) the flicker becomes even less noticable (ie. faster) while the brightness stays low.
The problem seems to be on the mainboard, because both my screen AND the broken one work just fine on my old board.
On close inspection I found a tiny burnt out IC close to where the WIFI-related circuits are on the board. Please take a look at the attached pictures.
It's a weird place for a display-related IC, but everything, including WIFI works absolutely fine. It's just the damn flicker. So maybe this is connected?
Anyone an idea / solution? Maybe even an app/kernel that messes with brightness settings?
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.

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.
Screen burn is a problem on AMOLED Displays. After 9 months my S8 had significant burn in due mainly to gaming activities. I don't enable AOD and limit screen time on to 30 seconds. What other measures can be taken to help save the beautiful display on your S9 device?
Use lower screen brightness. I try to use 50% or less depending on environment and my GS7 didn't run into any issues with screen burn-in.
... Seriously?
I've used nothing but OLED phones since the Galaxy S2 and none have had screen burn. Even my old S3 that i have as a spare is fine. I game quite a lot on my phones too, some times for hours with no breaks but still haven't got screen burn. I never even purposely try to avoid it either.
I know that constant high brightness levels can cause burn-in on OLEDS much faster though. I use around 30 - 65% screen brightness in general, but only because of battery reasons. My S7 Edge is ok as well and i had AOD enabled for 15 months.
Screens are not created equal though and some burn easier than others. Even when they're the exact same model. There's a channel on YouTube called "Rtings" and they're testing multiple OLED LG TV's, and some are burning faster than others. So maybe you just got unlucky with the S8.

Burn is inevitable with AMOLED, but newer phones seem more susceptible to it. I never had LED burn problems until migrating to the S6. Also, white backgrounds such as on YouTube tend to be the most damaging, because white color is made using all RGB pixels at once.
My AOD burned the number 2 into my screen. It was quite evident. Brought it to T-mobile and they confirmed it was definitely burn in.
Luckily I was within my 14 day protection. Had it replaced with no charge.

Just don't use the phone at maximum brightness for prolonged period and you'll be good. Never had burn ins on my S4 and S7, at least not yet, screens are still perfect to this day. I rarely set the brightness above 50%.
None.
If it happens I'll return it and get a new one. I use the device as intended.
I set full immersive mode globally using adb, AOD is off, screen brightness on auto but kept below 50% as much as possible, screen timeout is set to 1 minute. I don't play games more than 10-15 mins usually and I try to move 100% of whatever is being displayed on the screen after 30 seconds to 1 minute (even if I have to turn the screen off and back on to accomplish that).
A bit much, I know. But I had a Galaxy S4 back in the day using the screen very moderately, and within 3 months it had terrible blue burn in from the status bar and icons on the home screen Im guessing...
Taking no steps. There's no need whatsoever. People are still using Galaxy S3, S4, S5 devices with no burn in.
This whole burn in thing is taken way out of proportion.
If you get burn in so quickly, you should contact Samsung to get it repaired under warranty, because it's not normal for it to happen that quickly.
I had my S7E on 100% brightness 24/7 for over a year, with AOD, everything.....and saw not a single sign of burn in.
My S8+ had no burn in after a year of usage with AOD always on, with high brightness. There's literally no need to take any preventative steps. That's just overkill.

I use my device as I see fit. Not taking much in preventative for burn. More towards batt life. I have never really burned any device. My wife's s5 had Facebook burned in pretty good. I used aod for several hours at night. But it's been great on every Sammy device I ever owned
Way out of proportion. I mean any static image can and will eventually burn to a oled. But I'm sure I'll have a new device before it ever gets as bad as a several year old s3 s4
Well, first thing I'm doing is NOT using a dark theme. (With totally black portions). I found that using such a theme will create uneven screen wear (burn in) , because there's portions of the screen that just wont be affected, like for example think the YouTube app's video portion.
Everything I can...
This is my third Samsung with AMOLED. The first was a Note 2. I started playing a geo-location game that needed to have the screen on to get credit for moving around. So it ran for hours each day. Annoyingly it has a bright green box in the upper right (it's a button you use all the time), and it got burned into my display within a few months. When I got my next phone (Note 4), I took every precaution. I ran an app every night, all night long that cycles through all the colors, full screen, to aid in preventing it. I tried to mostly use my geo-location game at night with the screen brightness turned almost all the way down. It helped a lot. I went over 2 years before screen burn in started appearing. I think I made a mistake with the overnight app. I had the brightness turned way way down when perhaps I should have turned it up instead. I changed that and the burn in faded out for a few more months, but I would notice it whenever I used the game outside during the day (hiking and such), because I had to turn the brightness up to see the screen. Now it no longer fades and is every present on my screen. The phone is almost 3 years of use at this point though.
My last step I have been doing is using one-handed mode to change where that button shows up on the screen. I figure if I can prevent it from sitting in the same place all the time, it will go a long way to preventing the burn in.
Feedback from many different viewpoints is good. However it sounds like some people are saying 'screen burn in is no big deal. I've never had it'. Just because it hasn't been a problem for you, doesn't mean it's not real for other people or that's it's blown out of proportion. We all use our phones differently.

Screen burn in in less than 2 weeks from an always moving display (AOD)? Sound fishy.

Agreed.
It is what it is though.
Haven't turned it on once with my new phone.

I think that for the typical phone user, the only place burn-in is likely to be a significant issue is on the status bar, and maybe the nav bar. The S9 is my first AMOLED phone with soft buttons instead of Samsung's capacitive buttons, but the only place I've ever noticed any burn in before is on the status bar, and really, who cares about that?
If, OTOH, you frequently keep the screen on for long periods using an app with fixed in place, high-contrast items, there's probably not a lot you can do beyond reducing screen brightness. If the app allows any customization of those items, like changing colors, try to make them less bright.
Well.. having owned a few devices with AMOLED/OLED displays(S2, S3, S6, S8+, S9+), all those devices had burn ins, some worse than others.
Since the S8+, I made a habit to not max out the brightness(I'd go 100% manual on all my previous devices before S8+), l left it on auto brightness, and if I figure that it had gone too bright, I'd move the slider back to 40~50%. And also hide the navigation bar. While web browsing, I hide the status bar too. Throughout the one year of using S8+, I'm happy with how it was holding up. And continued with these habits on my current S9+. Won't say that those are compromises to the experience, if anything it's even better, with hiding the navigation bar and status, it gives it more immersive experience while protecting the display.
