I was thinking that since the OLED screen does not use any backlight, lighting up a few pixels just to form a little led blinking would not tax too much the battery.
I don't know, however, whether waking-up the phone entails significant increase in battery usage. A middle solution would be to wake it every 2 minutes for 10 seconds in order to display the notification and the let it sleep again.
What do you think?
Sounds good good but im not to sure about that... there was another post about having the illuminating back button flash, maybe both menu and back buttons.. alternating between each one with a speed setting?
i love the idea, but the screen is 'off' for a reason...
first of all i don't know if oled screens can 'burn' (meaning the pixels are still showing when they are suppost to be 'off', because they have been 'on' to long)
Also, if it means the chips that control the screen have to be active instead of inactive, your battery drain may be kinda big....
I don't know that OLED would have burn-in (that's more a CRT thing), but they might well burn out - they do have a finite lifespan.
But you're probably right, it would likely mean that the phone couldn't completely go to sleep.

well, in such a case we could rotate randomly the pixels to be lit up (as in real old time screensavers).
With regard to out of sleep battery consumption you have a point. Maybe we could just wake it up for a few seconds and then have it sleep again. In any case if we assume that the major battery draw is the typically screen, then such an arrangement might prove to be acceptable - at least in some cases.
Why not use the backlight on the menu and back button? They shouldn't use too much power or get burned?

Yes - I agree this is a very good alternative - yet I do not know how bright these leds are.
Nevertheless, I noticed that the screen is able to display a big animated icon of the battery charging even when the phone is off! (I just received it and I put it in the charger). Thus, I assume there is some kind of control of what the display shows without having to wake-up the system (at least the whole of it).
If this is the case, we could have some led like notification even when the android is in sleep!!
what you say is not necessarily true.. that icon is when the phone is off. which does not translate to being able to display something on a sleeping phone when it is on.. two totaly different issues ..

True. I will check whether it is displayed when the phone is on sleep (still off and charging). It implies, however, that the screen can be controlled (also?) independently of the OS.
(all in all the touch buttons respond / light up when touched though the phone is off and charging).
Go guys!
I'm waiting this modification to buy this phone!
I belong to you!
Up !
Very funny topic one year later !
NoLED, BLN ...
The community is very powerfull !
Thank you all
Guys, just search NoLed on market and it's already made ^^. However, following neldar thread on BLN, NoLed use about 10% more battery per hour than off screen. BLN which is found in most of the kernel ( Except damianGTO one ) use about 1% more battery per hour and turn on the backlight of the touch key. Hope this will help you
I'm no developer so i have really no idea if this would work.
But, as this mobile is a AMOLED screen, each pixels are lighted up and so not much battery is drained on a black screen.
What if we could somehow make something when a new sms has not been read and screen turns of, a black screen like this appears
Is something like this possible?
pic example, could even be smaller or just 1 blinking pixel.

I think to display a message on screen the machine would need to be awake, so it would be using more power than with an led notification (afaik the device can normally go to sleep then).
Your idea would still save power over just showing the lock screen though because you are right that using fewer pixels would proportionally reduce power usage of the screen.
I guess the hardest part would be making the device appear off - It would need to ignore screen and button touches (except power).
I was thinking about this the other day, is there a way to display the battery level while the phone is off? and not the led light to show a battery or a number with a %?
Nope. Lock screen percentage is as close as you can get.
As the title says, I want to be able to close the case and still be able to see the Clock and the notifications. I have made sure the lock screen has not code and the screen does not time out, but I hate that I need to eithe ropen the front or tap the circle just to see if there are any texts and stuff.
bump.
I am interested in this as well. What's the point of having beautiful clock faces when it only shows for a 3 secs?
Mine shows for 3 secs, dimms for 1 sec, then turns off.
I would like to see this too.
i need this badly
Could a pro tell us how?
I have searched long for the answer on this question as well... No luck so far...
Yeah, this should be changeable somehow.
now why would you want to do that? The G3 doesn't have an amoled display so i'm pretty sure this functionality would eat up your battery like crazy because whole screen is forever turned on.

It doesn't have to be on forever, just being active 10 or 20 seconds would make a massive difference in perception.
Install the app Keep screen on.
Works well for the quick circle clock as well
Hi, I'm a new amoled user. I've bought a op7t and I'm pretty happy with it.
But I read everywhere about screen burn problems.
I know this is a tech issue with amoled. And this is my first amoled display.
So do you have some tips for me to avoid screen burn? Someone talk about notifications area? Using maps (absurd), time-lapse and fingerprint is that all true?
Thank you in advance
I'll make an effort of sharing my experience with AMOLED screens and what caused the burn in
Persistent screen elements like the status bar icons and navbar at the bottom left permanent ghosting on the screen. The causes I think were the increased screen timeout (30 minutes) and using GPS with the screen on as well as having a navbar that wasn't translucent or changing colors.
Mind you this happened over a period of 3 years and I didn't notice anything unless I really looked for it. I watched videos and the ghosting didn't affect anything. Only on bright backgrounds such as a white screen or gray did it pop up. Not enough to be noticeable or hinder my viewing experience and I am very particular about that.
Tips I've since been using after getting that experience for my new phone (7T 1907)
1) Keeping screen brightness under 50 percent unless absolutely required
2) Quickly switching between various different apps for a couple of seconds when using my phone for a long time
3) Keeping the screen off while using GPS and occasionally turn it on for looking at directions
4) You can turn off status bar icons from inside the settings to prevent them from causing the burn in under the status bar settings
5) Not increasing the screen timeout to anything over 2 minutes
This is what I know and have researched about OLED screens in general. If you have anymore questions I'll be willing to help.
It has been over five months since I got it and replaced my old phone. So far so good
