Potential million dolar app idea

i dont want to give to much info away. But it has to do with auto screen brightness on lower end phones.
I dont know how to program it, so i can't make it.
Bassically the App would start running when the user turns his screen on. when his screen is on the camera would be instantly activated , then scensing the light of the nearby enviorment. Then auto tunne the light of the screen for best viewing
what do you guys think?
i dont know if this idea has been integrated into other apps like brightness motion or something

I'm sorry to tell you but it's not a million dollar idea
A) the camera will use some battery
B) there is some sort of brightness sensor which uses less battery already being used

Ya the camera might consume more battery than a light sensor....but if this can be done then who wouldn't want to try it out on their phone....without those sensors!!...

Its been done anyways, never understood why...

Its called an ambient light sensor and just about every Android phone has it.

And also problem, that it is too slow procedure, while your camera turn on...

The app Lux already does this. If the light sensor is blocked, it will use the camera and vice versa.

Screen constantly adjusts brightness...

Just received my tf700t and updated to the new firmware. I noticed that when switching from any screen back to home screen and even throughout watching movies on my tablet, the screen brightness constantly adjusts even with automatic brightness turned off. Its pretty annoying esp. while watching movies. Is there a solution to this problem?

Can't say I have noticed that, and I've used it both with automatic brightness on and off. Maybe try a factory reset?

I noticed the same thing - I believe it's the LED backlight adjusting when you go from bright-to-dim and dim-to-bright screens. It is annoying though. I'm assuming that I'll just get used to it (I just got my TF700 yesterday)...

So your saying that taking off the auto and setting it to the brightest setting and it still adjusts by itself.

Yes, I have noticed it as well. Doesn't bother me, though -- I'd rather have the system tweak itself for brightness than just picking a brightness off-hand and sticking to it.

I've previously owned the tf101 and never had anything like this happen. I use my tf700t at about 30-40% ips, and it constantly adjusts. I haven't tried it at full brightness, but it still is weird that it would keep adjusting even throughout watching movies. It almost like 3 or 4 subtle brightness changes when going from say the apps screen back to the home menu (on default wallpaper). I went through all my settings and googled it without success, so I'm figuring that people either don't notice or just aren't bothered by it. It's driving me crazy though

I noticed this...and thought I was going crazy. Thanks for confirming it's not just me and yes it drives me nuts. Hopefully there comes out a way to stop it.

Auto brightness was way too dim for me. So I've disabled it and set the brightness myself.

What I'm talking about has nothing to do with auto brightness. When it's turned off, there seems to be some type of secondary auto brightness that you have no control over because it constantly adjusts when switching through certain apps/screens and playing movies. Look closely at the screen and you should see it. I'm glad I'm not alone as a few others have confirmed this discovery as well. I don't understand the point in setting your own brightness when the tablet will still adjust itself with auto shut off. I hope a fix of some sort will come soon.

I have not noticed any change in brightness levels with auto brightness turned off.

It reminds me a bit of the brightness/contrast adaptation my SGS2 does -- only there it can be toggled under the display settings, whereas on the TF700 you're just stuck with it.

I don't think that the screen is actually changing brightness - just that the backlight is adjusting as needed depending on how much bright/dim colors are on the screen...
What's strange is that if I enable auto-brightness (which works great in the bright office), that effect seems to go away... Very strange...
I'm assuming that it's a battery-saving thing, but I'm really not sure...

I actually watched this happen (without auto brightness on) without transitioning to a new screen while scrolling past a dark image on a light forum thread. I think it's a tegra 3 thing. I know I read about t3 dynamically adjusting the backlight during video playback and saving more energy in the process than the t3 soc itself consumes during playback.
I've been using mine on power save mode so far. I'm betting the brightness changes would be more fluid and less noticeable at higher speeds.

Read your user manuals. It discusses the feature in its entirety.:good:

So that's probably your answer,
You running on maximum power saving mode. What you expect?
You asking tablet to save all power it can, and that's exactly what's it's doing.
Of course there's a chance of defect, hardware it software. But that could only be tested on a group of other tablets using same settings, to try to recreate what you describing.

I've noticed the same, as well as a few other users, we actually had a (sub)thread about this a few days ago here.
This is in fact very similar (or equal) to dynamic contrast we all know from LCD screens. Unfortunately I do not know the solution, but setting the brightness to as low as I need in any given lighting conditions helps.

Video: Samsung seems to have introduced black clipping/crush with software

It seems to me that Samsung has screwed up the screen calibration inadvertently in their cluster-F of an OS. The S4 shows black clipping in images, gamma test charts, and videos, but I found some remnants of a more capable screen here!
http://youtu.be/V7T4rEQt27o

Seriously Samsung, don't give a crap if it gives somewhat better battery life, FIX THE DAMN THING! What's the point of releasing an FHD phone and having that black clipping and blue tint? At least leave an option to switch it on and off.
Will be fixed with custom kernels as with S3/Note 2, hopefully.

Noticed this last night while multitasking.
Kind of annoying, I do think its software related because my SystemUI crashed at one point, among other things, and it stopped happening.

Correct. Whereas before going from one screen to the other would cause a momentary jump in brightness, then a quick lowering of brightness by a noticeable but nearly insignificant degree - post a ton of errors/crashes, it stopped happening.
At one point the phone jumped a few notches in brightness (without my touching anything). And from then on out, all my screen swaps from light/dark, dark/light, different apps stopped having that ever-so-slight adjustment.
So it *seems* like it is an adjustment made on-the-fly of sorts, and I would really love to just be able to disable it...

This was a major problem in the OG Note and was never fixed.

Samsung needs to fix their screen because it's terrible compared to other phones. I can barely see the screen in daylight when I'm outside.

As an experienced Android and iPhone user, this phone is the biggest disappointment of my life. The lag is horrible and there are so many annoyances like the screen brightness changing all of a sudden (with auto brightness off). We need CM10

I can confirm that this happens in Netflix as well. If you pause on a scene with clipping, and hold down the menu button, the clipping goes away or atleast improves substantially, right before the Netflix app fades away.
There definitely seems to be something crippling the gamma across the OS

Is it me or am I the only one happy with the screen? It's not that bad in daylight as long as you bump up the brightness and you can adjust the color mode on the screen so it mimics the HTC One color saturation.
Also I don't notice any clipping, fault screen perhaps?

I leave auto brightness on all day I live in sunny Miami Florida and I see my phone perfectly outside. I never have any jump of brightness but in the settings menu I do get a little bit of this blue smearing and whites go a little darker but its minor not enough to make you annoyed. I don't know but I'm having no problems with my phone and I love it

Go to the Play Store and watch the Trailer for Django Unchained.....no clipping? Clipping is present on every AMOLED, just to different degrees
As far as is my understanding, either the screen smears on grey on black, or you have reddish blacks. Some might not notice it or care really

The smearing can be reduced by using the appear app Scream Adjuster and setting red green and blue to + 5 to +10 depending on how badly it smears.

Yea it sucks. But an update can easily address this issue

can someone give me a specific example of where they're having problems?
I just ran the black/white/APL clipping patterns from AVSHD-709. Movie, Photo, and Standard all show no problems. Dynamic however, crushes blacks. Those who are having issues, are you all running Dynamic screen mode?
edit: upon further inspection, it would appear that 17 and 18 get clipped in movie/photo/standard. It's not perfect, and that's all this guy seems to be demonstrating, but I can't imagine a situation where any of you could be legitimately noticing it. It's well below 10% luminance. Just leaning back in your computer chair can clip that many shades of black or more on an LCD monitor. Just as an example; this would not show up on a calibration report, even if gamma was done in 5% steps instead of the typical 10%.
If any of you are really seeing crushed blacks, I would bet that you're using dynamic mode.

Then you need to exchange your phone. I got the 32GB on the 10th and installed the Titanium backup setup from my GS3 and the S4 destroys it in every way. Absolutely no lag, much better battery life, more natural screen saturation, although still oversaturated on the greens. I havent changed the default setting for the screen, which was set on adapt. I am a full time video editor and I just watched the Django trailer off the play store and it was flawless, blacks were crisp, no pixellation or overcrushed blacks and the brightness did not pulsate with changes in luminance from scene to scene. With auto brightness on in a dark room or fully lit room.
I do remember when I got the S3 with ICS stock how terrible the autobrightness was and terribly laggy camera was but after wither the JB update or custom ROMs, all that went away. But none of that exists on this 32GB one I have, so if you applied the latest update and you have the same probs then def get an exchange.

the black clipping is a known issue, and if you're still complaining about lag, swap your phone as everyone who's done that hasn't had any since. as for random brightness changes, noone's mentioned them since the ota

Got rid of the lag by switching launcher to nova and froze a lot of **** from AT&T and Samsung. It hasn't freeze ever since.
The smearing is present but only in the settings menu when I scroll up/down. Not a big deal but I hope it gets fixed.
Besides that the screen is gorgeous and have no complaints. Excellent battery life.

So how's the Gear 2 wake up behavior?

One of the most annoying things of the Gear 1 is the motion to wake up the watch. Is it improved? I watched a bunch of hands on but they all tell the same story. No word about the fact that the display can't be lit all the time and that you have to do some abracadabra to wake the device. Most curious about any improvements in this department.

well you can't have screen all the time due to technology used. AMOLED. if it would be LCD then you could have screen on all the time, but without background light (like in sony smartwatch 2). i already got used to blank screen, and i just turn the screen on/off with a single button.

I know. I'm wondering if they made the watch more sensitive for motions, introduced a new or better wake up motion etc . Definitely want to know more about that.

if samsung did not mention it, then probably it's the same.

That would be a detail for people coming from the Gear1.
If the battery life is better they might have add a more sensitive option.
Btw personally I dont mind to charge the watch every night. Just some routine. I like it even better than checking the battery to see if it needs to be charged again. So if they made the wake up motion more sensitive and could still pump one day out of the battery, it would definitely be a reason for me to upgrade. Otherwise I see no compelling reasons.

I understand what OP is saying. I'm interested to know that answer as well. I actually had to turn motion off because the watch constantly stayed on while driving all day. It would kill my battery. With it off and me pressing the on button as needed, I get at least 3 days of battery life. A better motion sensor could possibly solve this issue.

what kind of issues did you have? i had none with nova.

I read a hand on today where the reviewer said it does turn on with the flick up of the wrist but that it doesn't turn on right away, like a couple of seconds delay. That isn't good. I want it to be quick like the pebble when you shake the wrist slightly the light comes on. Hopefully they tweak that before it is released....

That's what I want. I move my arm to that wrist up position to much so the watch is almost always on. I wish it had the option to shake the wrist instead so I have better control.

Personally the only good thing about this watch is the motion thing. It works like a good 90-95% of the time. Wake up is excellent on it. However, it goes crazy when your driving.

Question How to fix pwm on this device?

It has pwm even on full brightness. I tried the pwmfree app https://forum.xda-developers.com/t/app-amoled-pwmfree.3898070/ but it still hasn't fixed the problem.
Doesn't it bother you? My eyes hurt while looking at the screen.

I've read a bit about it on the link you've provided. How did you know if our phones have it? I am quite interested in this!

You use the camera from another smartphone or another device to look at the screen of the a52. And you change the shutter speed or exposure in the camera until you will see the bars pulsating on the screen of the a52.

Oh well then it seems like most of my phones since 2015 or so have had that, and I've never really suffered from headaches from it, not that I've noticed.

You can't notice it consciously, but some people, including me, are affected by it. The thing is this could easily fixed by samsung, but they wont do it. Other companies have removed the pwm effects on their amoled screens.

Damn that sucks, especially when you know its an easy fix from the OEM to implement.
One thing though, from what I've read off the PWM Free apk page, it uses a transparent black overlay and increases its opacity as you decrease brightness. If that's the case then you could use Twilight to acheive the same goal, right? Just max out the brightness and turn off auto brightness, then use Twilight as your brightness adjuster, turning the bluelight option down. Could that work?

The weird thing about the a52 is that it has pwm even on max brightness, so probably twilight wont work as well. I will try it later though. Same problem on the premium samsung range: https://eu.community.samsung.com/t5...been-addressed-on-the-s21-series/td-p/2641628

Yeah, it still flickers even at full brightness. Maybe setting it at 60hz could fix that? I'll try it later to see if that could work. My previous phone doesn't have that issue at full brightness, so I'll gauge the difference based on the difference between the two.

I use mine only on 60hz and it still flickers.

Yeah, I've tested it and there is a difference between 60hz and 90hz, but the flicker is still present.
Edit: I also re did the test on my old device, a J7 Pro, and it stops to flicker altogether at peak brightness. So yeah, this phone has very prominent PWM.

I suspect you didn't actually have the brightness set to maximum. This cannot be set manually, but is only set when the ambient brightness sensor (front camera) is illuminated by a very bright light - the sun, or a very bright flashlight. The brightness of the display is then visibly increased above the normal maximum.

Well, if the max brightness can't be controlled then it's not relevant. In this review https://www.notebookcheck.net/Samsu...ntly-more-affordable-without-5G.539956.0.html they tested the pwm on the display with an osciloscope and it shows that when you manually set the display at 100% brightness it still has pwm. This is one of the worst pwm out there, and a shame for samsung to do something like this.

is a shame unless samsung make a change in the firmaware the a52 is a pain in the eyes i need to sell mine now i cant play any video game unless i want a eyestrain

Pwm sensitive here.
Samsung A71 was OK pwm 240 hz.
Samsung 21fe was OK pwm 240 hz.
Samsung s6 edge was OK pwm 240hz
Mi 11 ultra not OK pwm 480hz. Not OK even with anti-flickering or pwm_free / oledsaver app. Mi 11 ultra has Samsung display E4.
I really don't understand. Maybe is the highs and Bottoms in the amplitudes.

Works well on my galaxy s8

Hi. I realised the negative effects last year after a year of using amoled display on redmi note 10. It gave me headaches and also my eye power changed from 0.5 to 1.5 for both the eyes in just less than a year. I do 3 hours of use a day. That's how I learnt about PWM and the headache it gives to people.
edit - REDMI NOTE 10 died a week ago and I am searching for a phone which doesn't have PWM issue in it. For past 7 days I am using LCD screen and my eyes feels a lot better.
