Screen locking turns antialiasing off - can this be disabled? - Amazfit

Hi all from the new Stratos owner.
Screen is great. What anoys me is that antialiasing is off when screen gets off. Can it be disabled and keep better qualy of graphics despite screen being locked/off?
Thanks and apologies if this is duplicate - search did not gave me any results.

Its something that helps saving battery juice.. I dnt think it should be turned off... You can always use digital watchfaces that look comparatively crisper

Thanks for the effort, not really answer to my question.
P.S. My Garmin 935 has over 2weeks battery life with antialiasing on constantly (and even keeping second hand on all the time)... I apreciate hardware differences between them, and Stratos being more powerful, but screen itself (with brightness off) is not that much cause of a juice spent.
Any other thoughts or tweak possibility?
All - please avoid oppinions, instead post solutions or guidance if they exist.

[Q] What can we do about the screens brightness?

I've search for both "screen" and "brightness" without any results.
Is there anything we can do about the brightness of the screen? It's very low, even if you have it on max. Is it a hardware or software issue?
I've seen a lot of reporst of bad screen brightness, but can't say I've ever experienced a problem. I had more issues with my HTC desire, I could barely see it outside on a cloudy day. The XP I can see fine most of the time.
What are you using to turn the brightness up/down? There is a widget to turn it up and down, but it only makes it go up to 175 (iirc). I use power manager. This changes my brightness depending on different scenarios. Similar to juice defender type things but a lot more basic. The best part of it is the screen timeout and brightness settings.

oh cool, will check that out
Thanks,but don't disable sensor :-(
Brightness don't change :-(
That's one of my problem also, the poor brightness of our phone, At first I thought there is an app to increase it, but there's none..
When im using it under the sun, I cant really see what I'm doing to my phone especially when there's my finger print all over my screen, so i always bring my cleaning cloth.
Yeah i have tried every app out there in hopes one would work but that sensor just has to much control i guess.
Hopefully someone will figure it out eventually.
I guess some people are not bothered by it at all so possibly the people who would know how to fix it just dont care enough to.
On the R800x, there is no auto-brightness to enable. It is all manual. 100% seems to be bright enough to read stuff outside in the sun. I don't know that there would be a way to push it even brighter.
A number of people have been claiming that if you remove the pre-installed screen protector it becomes a lot brighter. Maybe that might help you if you are willing to risk the screen scratches.

Yeah by removing the protector the screen becomes much more brighter.. The toughened glass seems to be holding up quite fine though.
For a short 30 seconds experience with factory superglued protector, all I can say is remove it. Much better light sensor response, better contrast and much much much better finger swipeability on the mineral glass under the plastic protector...
Also now as I have phone, I'll see how to disable LS.

I was talking to Doomlord the other day about this, the ALS seems to be part of the kernel. The exact location of the sensor parameters is /sys/devices/i2c-0/0-0040/leds/lcd-backlight/als. You can edit those parameters but nothing sticks on save/exit.
If you want to see how crazy the ALS is, fire up logcat in adb and watch what happens when you pull the phone away from a bright light source.
The only problem is some people love the ALS, and some people hate it. I'm in the hate it camp. I'd rather be able to adjust full brightness manually. It would peg the CPU a lot less too in certain lighting conditions, actually improving performance.
To that end, wondering if there is some kind of kernel extension or module that can be flashed, or if it has to be the whole modified kernel that is replaced.

I found it in kernel. I'll publish it today. Stable, OC, and light sensor will be separated as module.
Everyone who likes it, will have it automatically on, and who don't can remove module from /system/lib/modules.

Problem: lightsensor and proximity are one device with one driver. So it'll have to be disabled in hw_config.sh

I tried to solve it through editing the hw_config file, but had the same problem of results not sticking/working correctly. Enable would switch to 0 for a limited time before switching back to 1, and definitely after a boot, but still seemed to be functional and operating as if it was enabled, i.e. the functionality appeared to happen more slowly than rapidly on the fly. Also, the 254 variable never stuck at all, so that test failed, heh.

Because some people still like it, so I can't disable it for everyone.
Now this is where problem starts: no LS config in hw_config so I can't manage power modes like on older Xperias.

I would imagine we could alter the settings.apk framework to include a checkbox to enable/disable Automatic mode for light sensor, and if off, revert to manual change. Is this a correct assumption? It might be easier for the end user than enabling and disabling a module at terminal prompt or yanking things from the system image or (heaven forbid) the running OS. It would certainly involve a bit more work, to be sure. However, could also just alter the framework to run insmod commands through BusyBox so that we can insert and remove modules. *shrugs* Just thoughts, not mandates. ^_^

Hello Blagus're really good, really compliments for the work you do for us now;-) I think that you release the modified kernel for the brightness?

Screen auto brightness problem

Ok i wanted to start new thread with this issue
got a question about the screen. Some times I can sense and see that despite of auto brightness off that the screen adjusts its brightness by itself. It is a little change but my sharp eyes can see this... Do you have a similar thing?
I can easly notice this when playing my country game. When I click on the building menu the screen gets brighter. When i cancel the menu the screen makes darker
Also in sprinkle when I use water the screen gets little brighter
I think this is because the Tegra 3 (or ASUS's implementation of it) adjusts contrast to conserve power. The changes in contrast make brightness seem to change.
I think their settings are too aggressive and they should either scale them back or add an option to turn it off, if possible. I'm sure it's nice for battery life but it does (in some very specific instances) seem to impact the experience.
Note: this is not a doom-and-gloom post. The Prime's screen performance is the best I've ever experienced on a mobile device, maybe any device, overall. So this is a bit of a nuisance but nowhere near enough for me to have an inkling of regret about buying the Prime.
This only happens on mine while in power saving mode.

I'm not sure, I'll have to do some more testing. I seem to remember it happening across the board.
I'll note that Battery mode really does make a HUGE difference in the screen's performance. Colors become very washed out, so much so that I'm really surprised by the impact.
Well in my case this thing occurs on every mode with the same strenght... That sucks
so anyone of you can confirm if this is normal? Do you have the same isue on your primes?
It seems the light sensor has high resolution and Asus needs to smooth up a bit the auto-brightness algorithms If your screen goes up and down then simply disable auto-brightness or change lightning conditions

Like i said auto brightness is off. Can anyone install my country and check his out for me? Just enter build menu and chec if the screen gets a little brighter
it has nothing to do with auto-brightness... Its a feature of tegra 3, it can change the brightness of each pixel to give you the best image and use the least amount of power.. unfortunately its just annoying and not implemented well.
And you cannot turn it off.
Ya I noticed this too last night and thought that I had a defective screen. Made a thread about it earlier. http://forum.xda-developers.com/showthread.php?t=1421002

I have had the same issue. Clean ur screen often. Static electricity is one of the bigger reasons this touchscreen becomes too sensitive. When this happens, grounding myself usually fixes the problem.
I read about this in another post....Go out and get yourself a ZAGG screen protector. Doesn't matter which phone model or make, as you will have to cut it down to the TS size. You can find many of these on sale from earlier released phones...the best to find is the Note 2....this gives you the largest sheet of their protection material. Just in case you have to do multiple tries.
Good luck

When I receive my watch I'll build mod for lower brightness (longer battery life) and touch screen sensitivity tweak...
For now, root your device and wait for mod - we have to edit few files, cleaning screen or applying screen protector won't harn but won't help either.
It's ridiculous that developers edition comes last, but that's the way it is...

Mine was originally WAY over sensitive as well... but after installing Loki's ROM and/or the patch I don't seem to have the problem. Don't know if it is related but if you haven't patched or updated.... DO IT!

[Q] Screen flicker problem

Hi everyone.
I love the TrueSmart but I've got a problem with the screen.
There's a flicker on it. The whole screen flickers and it's particularly noticeable when the background is white or any other light colour.
Has anyone else experienced this and what are my chances of getting it fixed or replaced under warranty?
Thanks for any advice in advance,
HRH.
sounds normal, mine too

Now that's a helpful comment. Thank you. If I set the screen brightness to maximum then the flicker goes away. Not ideal, as I've never set any device to max brightness in my life. Never needed to. But at least the flicker goes away.
I just hope it doesn't make the rubbish battery life even worse.

Ah. I was thinking more in terms of down rather than up (but I didn't say so...). Indeed, it's bright in the first place and raising it will probably have an impact on battery life.
I think Lokifish reported some time ago that the screen was ridiculously over bright even at the minimum setting and that there was no change in brightness if raised over 50%.
I used Lux on mine to drop the brightness way into negative values. I have noticed no annoying flickering, but there were early reports of nasty flickering on some samples back last Fall.

Repeated burn-in issues.

Hello, recently i sent my phone to warranty because of serious screen burn in issues, they replaced my sceen, which had more light bleeding issues, but i wouldnt mind that, as the burn-ins were gone, but to my surprise, yesterday after about 3hrs of constant on screen texting in whatsapp, the burn-in started appearing on the new screen, i am seriously pissed off, i really like this phone overall with the features it offers and so on, but the quality control... Wtf LG.. I now have bought a phone which i should just send for warranty repairs after a period of time?
Just wanted to share my experience with you, i still have a gpad 8.3 thats is still rolling on the latest 7.1.1 and has no quality issues and a robust metal build whatsoever, but this is just annoying...
Im sorry to hear about your issues with g5. Its a great device, whats wrong with your screen? Light bleeding whad do this mean?

i think it would be interesting for all of us to know the period when it started to happen for the first time and then when exactly after the replacement?
I for myself got the screen replaced about 2 month ago having the screen burn issue as well. Phone IME starts with 604. Since the replacement no issue for me so far..but i am not so sure if it the problem is solved with that and the screen burn in starts again after a while again......

Its indeed interesting as it really seems to not appear at the beginning, and once it shows up it starts to get more noticable over time, for example as i said, it occured after heavy using whats app for about 3hrs most of the time with auto brightness sometimes hitting the highest levels, right now i can notice the burn in, but its not at levels where it would become disturbing, ill see how it goes, if it progresses and so on..

...that some users have installed "sFilter BlueLight" app to prevent this issue!
...as some users reports,it is not granted, that this issue never returns on changed displays because it seems to be a general fault...

Sorry, but to me the reply seemed non-friendly, as it would be addressed to a rookie user, who hasnt done his research, maybe im wrong about your post...
But overall, yes i have seen all those threads, and unfortunatley, as i have mentioned in some other LCD display threads, the app could basically be a temp fix for the issue, when its not at a disturbing level, as its a cause of a faulty panel.
At this point where my panel has been already replaced, i cant really keep track of its model.

Okay so lets go through this together.
A burn-in only happens with amoleds as this is permanent. We have LCD panels so we have image retention which is non-permanent.
A LCD is a liquid crystal display. Means you have a certain state of the crystals. When you apply a voltage the crystals rearrange themselves and block light. This is why we need a background illumination. Anyway once you use it for a longer period with a semi-static or a static picture (like whatsapp typing bar, google maps info boxes, keyboards etc) the crystals start to shift in their relaxed form towards another state. Blue light is due to its short wavelength energy consuming -> high voltage applied -> faster image retention.
That's why blue light filters do work to some extent. (With cf lumen and root you can adjust to use less blue instead of having an overlay draining additional energy)
This liquid crystal thingie is dependent on a lot of different parameters, that's why some get it faster and some slower. My 1,5k$ thinkpad has the same issue with the navigation bar being a persisting image after 10h+ of browsing.

So this is actually not a warranty issue. LG also returned phones unrepaired as this is the negative side of a lcd and considered standard behaviour. Go for an AMOLED the next time as they can't suffer from this, but once you have image burn-in you will never get rid of it. So doesn't really make a difference.

Okay so lets go through this together.
A burn-in only happens with amoleds as this is permanent. We have LCD panels so we have image retention which is non-permanent.
A LCD is a liquid crystal display. Means you have a certain state of the crystals. When you apply a voltage the crystals rearrange themselves and block light. This is why we need a background illumination. Anyway once you use it for a longer period with a semi-static or a static picture (like whatsapp typing bar, google maps info boxes, keyboards etc) the crystals start to shift in their relaxed form towards another state. Blue light is due to its short wavelength energy consuming -> high voltage applied -> faster image retention.
That's why blue light filters do work to some extent. (With cf lumen and root you can adjust to use less blue instead of having an overlay draining additional energy)
This liquid crystal thingie is dependent on a lot of different parameters, that's why some get it faster and some slower. My 1,5k$ thinkpad has the same issue with the navigation bar being a persisting image after 10h+ of browsing.

Thanks for the interesting article on LCD artifacts, however, i wanted to say some things:
As my for my first panel, that got replaced, image retention was pretty hard, as when the phone got warmer, it became really disturbing and barely usable as the keyboard and status bar started to ghost on grey background apps such as xda, the only way was to let it cool down and wait till everything disappears, as soon as i started using my phone a bit longer, the problem resurfaced very quick. So it clearly wasnt a normal reaction. Just to add, no CF.lumen like apps were able to help back then.
My current replaced panel is showing only minor signs of this, it becomes more apparent on longer usage times with the same elements and the ghosting is barely visible with not so intense usage, so i hope that this wont eventually get stronger as before. As it would seem to be a natural usage reaction, i still consider this an issue however, cause none of my previous LCD phone had anything like it, not even my LG Gpad 8.3. So im gonna try to apply warranty again if needed, as repair services seem to be pretty helpful in my country at least, as long as they have spare panels in stock.
And about amoled, i think ill pass that for a while, i have seen enough samsung demo units in stores have serious homescreen burn-ins.
With LG G5 the quality really seems to be an issue, yes there maybe lucky people with good units and so, but overall it is pretty disappointing, as feature and hardware wise i really love this device.

I see the so called expert stopped responding like a retard. I had the same problem I just lgup and flashed stock all over again about 4 times and it started to show improvements. As of now I got rid of the burnt images on my lcd
