Need help building screensaver MOD as found in Nokia N8 & N9 - Samsung Galaxy Nexus

Nokia phones such as the N8 and N9 that use AMOLED screens have the ability to display "screensavers" when they are locked, meaning they'll constantly display the time, date, and notifications using a minimal amount of pixels even when locked. Since the screens are AMOLED, you only have to power the relevant pixels and the impact on battery life is negligible whether the screensaver is on or off. A handful of LEDs displaying only the time would not waste that much battery really. It's not like an LCD screen where it's all being back lit. If done right, only the few LEDs being used will be draining any battery as something like time is always maintained whether the screen is on or not so it wouldn't result in a wake lock. I know the Galaxy Nexus has an AMOLED screen so the hardware can support it, just need to apply some heavy knowledge that i dont have at the moment.
But it's possible, I don't know if there is anything in the Java layer of the Android OS that lets you directly turn on and off individual LEDs directly. Looking in the c/c++ libraries for something like that would be where to start.
I need help from devs that can get this up and running. I feel like this could be a great addition to all ROMs out there for not just the Nexus but all Android phones!

[Q] Just got my nexus, the screen dimming is annoying. help please.

I just got my Galaxy nexus (an hour ago), and I'm getting around using it pretty well except for one thing which is annoying me big time.
The screen seems to dim or change its color balance when viewing certain things. Whites are usually dimmed at most times, but when I view other things, the dimness goes away and whites become very radiant.
It seems like the phone is adjusting automatically to things on the screen for the sake of energy saving. How do i disable this!?
Yes, I have my Brightness on manual and set to full. That is not the issue.
okay wow this is getting annoying... Two more issues:
1-The thing won't transfer files while im using windows 7 "the device has either stopped responding or has been disconnected". When using OSX Lion, it isn't even detected.
2-There is chinese text here and there no matter what I do for language settings.
This is my first android phone ever, and I'm not liking the experience so far...
Look, I've tried searching for these two issues, and I did not find any threads with them resolved. Maybe I'm computer illiterate. Maybe I have a very low IQ, but can you just help me resolve these issues IF you know how to resolve them without just going into my thread and be like "Oh look, another noob", and proceed with leaving?
PS: I AM A NOOB.
Protip 1. Read up on amoled technology a little. And then read some of the issues some phones like galaxy s2 had. Your dimming is normal. It sounds like you're just more sensitive to it.
Protip 2. Download the appropriate drivers. In device manager, you want it to say android adb interface when you're phone is plugged in.
Protip 3. Take a chill pill. It is okay to be a noob. It happens. Your attitude comes off as annoying or you're freaking out over nothing. Solving problems take time and we are not sorry xda can solve them instantly for you. Patience, amigo.
My grandma beat me down and took my nexus. Sent from a jitterbug with beats by dre.
You might try turning of Auto Brightness and set it somewhere you feel comfortable... I just decided when I got this phone that I'd make myself get used to the adjustments and it's worked out well.
IMHO the adjustments going from white to black are less noticeable on 4.0.3
As far as the dimming, you have Auto Brightness on. Go to settings, screen and set the brightness to something else.

samsung drivers
for the drivers use this post

PDAnet installs the drivers for you nice and easy, then you can remove from your phone and pc and the drivers will stay behind.
at this time there is no way to disable the screen dimming function. samsung's other phones have this feature as well, with an option to disable it in settings. its a power saving feature. for whatever reason google did not give any option to turn this on or off. so for now we have to wait if maybe a ROM can disable it.
For OSX you need to download Android file transfer for it to be seen.

Thank you everyone ...Sorry for the attitude earlier.
It seems like I got one of the GNexus phones which have a really good screen (The colors are just mind blowing), its only the dimming thing which is getting in the way. Also, I've tried to update to 4.0.3 and checked out the developer's section of the GNexus forum, but the steps are kind of overwhelming and I'm having my final exams at university right now, so I'll have to wait for a week to just sit back and read everything slowly and correctly.
One more thing, is there a download link to the official 4.0.3 mod ? It seems like everyone here prefers modded images one way or another.
lol. the dimming you are referring to is probably from current draw or a trait inherent to amoled. some people have mentioned they notice "dimming" like on white background browser and you pop up your keyboard. the white will get dimmer or yellower, or black more grayish. this is what you're talking about?

Its the opposite. When you draw the keyboard out, the whites get brighter and stronger. I don't have yellowing on my phone (thank god), but I do have dimming.
top make it simple:
The more the blacks = The brighter/stronger the whites.
Clearly a voltage issue for power consumption's sake. As the phone physically switches of diodes to achieve true blacks, more energy flows to lit diodes and they in turn become brighter.
Isn't there some sort of tweak deep enough to give full power to all diodes at all times regardless of what's on the screen (Full power even if the entire screen is white) ?
Firstly, welcome to Android. Once you get used to it you'll love it. I gave the same problem Windows 7 sometimes usually large video files and need to say that the adb drivers are not required to transfer files to the phone - I don't have them installed and I can still transfer data.
I have to say this is my first amoled device and I haven't noticed any dimming unless I have auto brightness on of course which I understand you don't.

ah yes. you're correct. i had it backwards.
I have the same issue with transferring large amounts of data using Windows 7. Looking for a fix too.
Investing the time to learn how to setup the SDK and using ADB will be well worth it.

Out of the three results I found searching for this topic, I'm glad I checked this thread.
The exact thing I was wondering was:
Is there any way to disable the screen from getting brighter when my keyboard comes up on the screen?
From reading your response, it seems that the screen getting brighter is a result of the design of the screen, suggesting that there is no way to stop it from happening. The only thing I've been able to do to make the screen remain at the brightness I set it is to change the theme of my keyboard to a brighter or lighter color based theme.
I'm using Swiftkey with the Neon keyboard, it looks great and I love it!
I had a Samsung Vibrant previously to the Galaxy Nexus, and there indeed was a "Power Saving Option" in the settings and if I remember correctly that stopped the screen from getting brighter with the keyboard on screen. Has any fix / ability to change this on a stock Galaxy Nexus running JB been found? It's just barely annoying enough for me to notice it, plus I'm a stickler for more battery life and I can feel my battery dying the brighter the screen gets. ( I know this last part may be a mental thing, but still. Haha. )

Anyone with a VZW Gnex have screen burn-in? I have 0...

Just wondering because I've seen a few posts already about screen burn-in, but I've had my Nexus since launch and have no problems at all. Is it because the people that are having the issue are using the GSM version and have had it longer? Is it because those people have their screens on all day?
I'm just trying to get a baseline to understand where the problem might be coming from. Don't get me wrong, I'm not in highschool so I have no need to keep the phone screen on 4+ hours a day (I average somewhere around 1:30 a day, but most of that is reading and answering texts/emails)...but just curious.
For anyone with burn-in problems just post which version you have (and when you got it, if you could) and the average screen on-time per day that you have. Maybe this could lead to a "best practice" document to keep it from happening to others!
I am afraid that this might be a redundant post you just made.
There is no physical difference between GSM and CDMA variation's SAMOLED screens. There should be more difference between which factory and/or country it was made than between GSM and CDMA.
I know you have already, but please refer to the posts made on:

And I'll re-post the post I made over there on here as well for your information.
----------------------------------------------------------------------------
This will probably happen to all of us to some degree sooner or later.
The image retention that lasts 1-3 seconds we might see within a month or two usage is actually one of the characteristics of AMOLED "Ghosting effect"
which is not the same as AMOLED "reverse led fatigue" (or although technically incorrect but more widely understood term "Burn-ins") which maybe seen as permanent image retention shown as yellowish outlines of icons / keyboard outlines, etc.
Sadly, there's really nothing you can do about this problem after the fact, except to change the screen itself if it is really bothersome. Or you may try to change/delete/make transparent of the permanently placed icons/other objects/pictures to try to reverse these effects.
The only preventive measures would be changing screen rotation from vertical to horizontal, and make sure you don't have the screen on at a stay still image (preferably set auto screen off to 30seconds or so.)

I'm sorry, you misunderstood my point of the post. I realize the hardware is identical (as far as the screen is concerned), I'm more interested in kind of how much screen on-time has a strong chance of creating permanent burn-in. I have a max of around 1:30 of screen on-time per day and I haven't seen a hint of burn-in...so I'm wondering if there's some magic number of on-time that will cause the problem to a much higher degree.
What I'm really hoping for is that, for instance, if we find people with 2:30 of screen on-time seem to really have the issue but people with 2 hours or less don't...then it might be a helpful practice to kind of keep screen time to a minimum above that. I realize it's not really helpful for most people (because nobody wants to curve their usage), but it's a limitation of the hardware.
Or maybe if a majority of the people with the problem seem to keep on the screen for 15-20 minutes at a time...that would help, as well.
Its going to happen. All amoled screens get it. The 2 verizom demo units at the store here have it really bad cause the screen is on all day. If you use transparent top and bottom bar, full screen in browser, and rotate your screen periodically, you can avoid the issue.

Oddly enough none of my previous amoled based devices (captivate, SGSII, Galaxy Note) shows any signs of burn in but GNex shows slight ghosting/slight burn in of the notification bar. It's feintly visible when i open the xda app

Smart Stay on the GN. Possible?

So the Galaxy S3 will soon be available, and by far my favorite feature is the Smart Stay that tracks your eyes to keep the screen on as long as you continue to stare at it.
Now, we all know that ICS has built in face recognition via the face unlock, and obviously it has the capability to track your eye movement so that way it knows when you're blinking. I wouldn't be surprised if Samsung is is just re-using that capability for the Smart Stay, the question is whether this can be implemented on the Galaxy Nexus without any significant performance hits.
You basically have to figure that the front facing camera is close to being always on as soon as you turn on the screen, which begs the question of what sort of processing power it would take to keep that service constantly running in the background. Obviously the S3 isn't going to have any problems managing that thanks to its brand new processor, but the Nexus is now almost a year behind in terms of processor hardware.
What do you guys think? Would you still use it if it made a significant impact on the battery life or general performance of the OS? Any developers care to comment on the feasibility of implementing it on the Nexus?
no i wouldnt use it. it would cause a strain in the battery life. if it could be activated for CERTAIN apps like dice player, youtube etc etc i might consider it.

Well, I already use Tasker to adjust the screen timeout to different values for each of my apps. And of course, most video players will keep the screen on by default while a video is playing.
The point of this is to eliminate the need to manually set the timeouts for 99% of your apps. There are only a few that you're going to want to keep the screen on indefinitely, but for the rest it might actually yield better power savings, because then instead of a default 30 second timeout the screen might end up turning off more quickly and frequently, negating the power loss from keeping the FFC on.
Basically Smart Stay is doing for your screen what stock Android and most ARM processors already do for background apps and your CPU cycles. Anything that's not in focus gets turned off or gets lower priority, in turn leading to massive battery savings over the traditional "always on" approach with old x86 processors.
I too would really like to see this ripped from the GSIII rom to play around with. I doubt it would save a measurable amount of battery life but its possible and I love playing with new features.
any one with SMART STAY APK FOR GN
No significant battery drain increase
In fact, the front facing camera is not always on. It just turns on and checks your face presence at the very last moment just before the screen timer runs out. So, if your face is detected, then the timer is reset and the camera goes standby till next check, else - the screen goes off.
Turning on camera for a very short period will not affect battery.
I would love to have this feature on my GNex too.

It is not an apk. It is a feature built into the framework of Touchwiz. It would take some major hacking to get it to work on our cameras and AOSP for that matter. I'm not saying it won't be done, but it will not be as easy as just installing an apk. The eye icon showing that it is on is in a place that is reserved for system stuff(right half of the notification bar). I really want this too and think it is a great feature. You have no idea how many times I have been reading blogs and/or certain webpages and the screen starts to dim and I have to hurry up and finish reading or touch the screen which interrupts my reading. It is an easy task, but this smart stay feature just makes so much sense to me.
Hopefully it'll be a built in Android feature on Jelly Bean!
I wonder if this works well in low light situations, like reading in bed.

I doubt it will. But then again, that's useful feature. Hope, it'll become de-facto for future Android releases, so that all coming flagship smartphones, including nexus line, will have it just right out-of-the-box.

From Cyanogen (Steve) on his Google Plus page of him describing the SGS3:
2. Smart Stay. Probably my favorite feature. When the phone is about to time out and turn off the display while you are reading, the camera will snap a picture (with zero shutter lag) and do a face-detect. If it finds a face, it stays awake. It works brilliantly.
I've found Screebl Pro to be perfect for keeping the screen on while i am using the phone.
Well worth the money.

I want my watch to look like a watch. Any apps for always on mode?

So like the title says I want my watch to always be on. So not ambient mode I hate the on and off crap. I want a dimmed but always on watch face if possible. Not worried about battery. Any suggestions?
There's a launcher (?) I think called Swipify I've seen mentioned multiple times for this. There's also at least one face available for purchase on the Play Store that allows you to choose how long it stays on, including always on. I bought it for that gimmick but never really used it. I think it's the "A06 for Moto 360" face.
In any case, understand that "always on" won't make your watch any more a watch than it will a brick, as you're looking at probably less than one hour of battery life with the screen always on.
1 hour is exaggerating. Either way the whole point of these things should be to be a watch first and foremost, and a notification hub second. LG G watch has a always on option built in and it lasts all day just fine, so I do not think what im asking is too absurd.
Well, you're asking if there are apps to do that. I answered that much.
But as far as what you're hoping you'll get, you seriously need to readjust your expectations. It sounds like you didn't do your homework prior to buying this watch. Undoubtedly this is the nicest looking smart watch now. But the battery life is not great. I get about a full day's worth with the screen turning off constantly.
I can guarantee you, you will not get a full day's battery of this watch with the screen always on. I don't know much about the LG G Watch, but I also highly doubt the whole day of battery you're talking about is with the screen on always.
I get what you're saying. It would be ideal. But battery technology is not at a point where it can power a full LCD screen for a whole day on a single battery charge. Try either of the ones I suggested and see how far it gets you. I might do it just for testing purposes at some point.
Take it down a notch bud. I did a lot of research before I bought this device. Perhaps you should do some with the way screens operate. You can in other similar watches like the G watch have everything turn off and throttle down but keep the time on the screen. The g watch turns everything to black and keeps the time and date still on screen. No reason this watch cannot do the same. I was merely asking if an app was released yet that does this. As most apps like the one you listed does this but keeps the CPU throttled up and the screen drawing more power. Hence why the battery gets killed. Do some research before talking next time. there are a million videos on youtube showing you exactly what im talking about.
Love the watch not complaining, I just want to squeez all the goodness out of it I can.

The difference is because of the display technology. As you know (or may not?), LCDs illuminate the entire display, whereas OLEDs (LG, Asus, Samsung) only illuminate the individual pixels, thus reducing power consumption by utilizing a simpler display graphic to use as the 'always on' portion.
To have your Moto 360 always on would be a huge drain on the battery life because of the power consumption to illuminate the display. LCDs are simply not capable of selectively illuminating pixels.

The reason the g watch is able to is because it's built with a larger battery. I had the g watch briefly and it was nice in terms of battery but just didn't hold a candle to the 360 IMO. It is a quality device though.
I'd like an always on option as well for my moto 360.
The always on mode ...is not actually a always on totally. ..it just dims to show only the dials and not the back ground. ..the lg g watch R and the gear live with oled screens will burn in if they are totally always on. .
But yes. .using apps like facer..you can select which layer you can keep dimmed on always on mode on the lg g watch. ..but that will eat battery up.

Not sure if this helps but like you I like a watch to be a watch and very close second I really like all the features for notifications that the smart watches make. I have had my Moto 360 for a little over a week now and I use it for keeping time and getting the basic notifications like SMS, Emails and Google Now info like weather. I do not have any other apps installed and with the Ambient Mode ON and brightness set to 2 I have been able to get 36 hours (at most) out of it with light to moderate use . The watch face I use is the preinstalled digital one. It dims just right but it will go to a black screen when there is very little movement detected. I can very slightly move my wrist and it will activate the dimmed time mode so I can see it without having to drastically twist my wrist and bring the watch up to my face.
Hope that helps.
If you find what you are looking please be sure to share as I am interested in this also.
Just to satisfy curiosity, I went ahead and tried this "always on" thing. I used the "A06 for Moto 360" face I mentioned in my initial reply, which is paid for on the Play Store so I won't link. It's not that great looking either, but it does have the option to have the watch Always On.
So, fully charged, I disconnected from the charger at 12:16 PM and changed the face to the one in question. I enabled Always On and set Brightness to max. With no usage of the watch other than to swipe away notifications and to use as a watch (i.e. looking at it for the time), the battery ran out exactly at 4:54 PM, or 4 hours and 38 minutes later. Admittedly, this was longer than my estimated one hour battery life, but again I wasn't doing anything with the watch. I didn't reply to messages, I didn't play games, I didn't check my heartbeat, I didn't control music. Only swipe away notifications and look at the time. Not quite 5 hours.
I guess it may be worth it if you're using a fancy face and going out for a date or something and you're fully charged before going. But it's useless as a daily driver with that kind of battery life.
Your very wrong. First and foremost it should be a watch. I bought a pebble for that same reason. Now before you go saying it's different due to it's e-ink display, I also own a Microsoft band and it's a color screen. I have my band with the watch always on and I user the sleep monitor every night. It easily lasts through almost 2 days and that's with constant notifications and checking pulse often.
It can most definitely be done.

So what's the point of wanting the screen always on? Are your eyes on the screen with your hands at your sides? Are you trying to show off? I don't think the whole "it should be a watch first & foremost" thing is a good enough excuse. As far as I can see, I can tell the time just fine without the screen being on 24/7. As a matter of fact, I guarantee I can tell the time every single time you can if we check our watches at the same time. No added functionality. Decrease in battery life. I see no win here. But to each there own. Charge your watch every 3 hours. I'm happy charging mine every night.
It's definitely wanting others to see his watch when he's not looking at it. Otherwise they see a black screen. I wanted that too but then realized I couldn't and moved on.

I only get 10-14 hours out of mine but I have a bunch of apps installed. Not sure where the battery drain is because its not like most of them stay running. Maybe google fit is the big drain, but its a nice feature and I don't need much more than 12 hours. Hopefully in the future this will get an easier root (without the interface clock) and an underclock for more battery life. That's very possible. I don't need my watch running at 1 GHz and I'm willing to bet the kernel is a huge part of the battery problem (as well as the smaller battery). But hacks could fix the watch I think.

[Q] Show clock without even activating screen. Possible?

Hello everyone.
First of all I'd like to state that I'm a massive noob on this forum, so if I'm being stupid for not finding a thread about this subject yet, please refer me to it. My apologies.
I've recently bought my LG G3 like 2 months ago. Now, I'm the type of person that likes perfection, so I've already tweaked my phone to the max (without 'hacking' into the system though), for as far as I'm concerned.
I was wondering if any of you know an app or trick to always show a digital clock on the screen, even when it's locked (untouched). I've read on forums that a lot of people complain about battery draining owing to the latter. Though I'm searching for just a tiny, dimmed clock on top of my screen so I can always look up the time without even tapping the screen. My logics tell me that those few pixels used will never really benefit to massive battery draining, and even if it would, I'm still curious whether it's possible yes or no.
I've tried the NoLED app. But like most apps, this is just another Daydream tweaker, which obviously is not what I'm looking for.
So in conclusion, I'm looking for a tiny little clock destined for the top of my screen, always visible, dimmed (to save battery life), not in the way Daydream does (since this leaves the entire screen on [draining more battery life than my idea IMO]).
Anyone know a trick, app or tweak to achieve this?
Thanks in advance!!

With the LCD screen on the G3 (and most other phones), you can't really do what you want. Whenever the screen is on, the backlight is turned on for the entire screen. So even if the clock only takes a tiny bit of screen, the backlight will use the same amount of power as if the clock took the whole screen.
Only OLED screens, as used on Samsung, Moto, and the Nexus 6 allow the device to light only specific pixels.
