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 flicker on low brightness

Do you experience screen flicker for your tablet when;-
1) Brightness set low manually. espicially at night !
2) Auto brightness set but flicker comes again when screen brightness is low in dark room.
3) Wifi is turned on and signal is low.
note : i disable the "auto adjust screen power" and provlem still exist on low brighness !!

My friend has the same problem and he can't figure out the reason :/

In GT2 i don't have this problem but with nexus7 yes.

is that individual problem for this tablet or all of galaxy tab 2 7.0 have this problem ??
please what should do ?

i noticed somethings :
1-screen flicker on low brightness under 20 % when i rise it above 20 % it gone !!!
2-it show clear on background color white !!!
3-that happen sometimes not all time and when i Lighter down screen a little by little the problem gone !!!!!!
waiting your answer ..
thanks

Reply me too. I have flicking problem (flicking on low level of brightness) on my P3100.Android 4.1.2 Official.

Since you are using the official firmware, then we can rule out the possibility of a bad modification from custom firmwares as the cause.
First thing to try usually is to see if the problem still occurs after a fresh factory reset, so do backup your stuff first.
If the problem still exists after a factory reset, then it could very likely be a hardware problem with the LCD backlight & you should send the tablet in for servicing.

the problem almost solve when i use app ( screendim)
www.4shared.com/android/h9Qv3UW8/ScreenDimFull.html
why is that ?!! what do you think ?

I have noticed this same problem with GT2, but no where near as often as with my Nexus 7. Ive also noticed my polarized sunglasses have less impact on the GT2 than Nexus 7 when the device is held in landscape position. I've just gotten used to the flicker I guess, because I rarely notice it anymore.

AW: screen flicker on low brightness
Same problem on my tab below 30% of brightness. I'm using Custom Auto Brightness to solve the problem.

I didn't change anything else in Advcanced preferences.
I use CM10.1.

i use app ( screendim ) like i said about one week and it is very simple and the problem almost gone when i put on low brightness !

Actually these are considered workarounds rather than solutions.
I use my Tab 2 at below 30% brightness as well on stock (albeit rooted) ROM, it works just fine.
If the root cause is likely to be a hardware problem, then you should send it in while the device is still covered under the warranty to replace the LCD.

actually it happen with me only on lowest brightness and only sometimes not all the times and only sometimes when i turn screen on for 30 seconds and then it gone !! and when it gone it isn't come back until i turn screen off and on again (and not all the time ) !!
really that made me crazy !! but after use app ( screendim full ) the problem don't show almost time on low brightness !!
what do you think ? is that wrong to use apps to soleve problem or should take it to SAMSUNG service ..because it will take week to diagnose problem !!
is there any apps that can make backup to all apps and all settings and all homescreen settings and games saved for restore it if service make data reset for tablet ??

Right, I've tried 4 tabs at my local dealer and everyone had screen flicker on low brightness - more or less. Especially when it's dark it is easy to see. 2 of them showed the screen flicker after a short period of time while the screen was activated. The other 2 tabs showed the screen flicker after about 10-20 minutes. Every tab came out of the box. I think it is caused by a cheap LCD panel.

On my panel screen brightness below 30% is too dark for me. So it doesn't matter for me. So I set the minimum brightness higher via Custom Auto Brightness.

That's what I'm afraid of. If I sent it to Samsung and the screen flicker doesn't show then I get the tablet back.

Make a nandroid backup for example.

Interesting, I was wondering which country/region do you all reside in from which you purchased the Galaxy Tab 2 ? This sounds like a batch problem if so many people complain about similar issue.
From where I hail, & based on the local forums, I have never heard of this issue with Galaxy Tab 2 in general until here on XDA Developer forum.
I may not be an expert but from the description of the problem by various members, it seems to be a serious hardware flaw that ought to be replaced under warranty.

if problem stop at this point that okay and it isn't bother me anymore when i use app ( screendim ) ...but i am fraid to developed to more than that !!!
if there is expert tell me will be more than that with screen or not ?

[Q] Tune auto-brightness

What's the best way to tune the auto-brightness on the N5?
It's a bit too bright at night, I want it to go lower. I tried a couple of apps, but didn't really work too well, or maybe I couldn't figure out how to configure them too well.
Otherwise it's mostly fine, other than being too quick to react to only slight fluctuations in ambient light.

Yeah, its waaaaay to bright. I had to go manual on it. There is no way to control automatic brightness on stock android. You would have to wait for custom roms to be able to adjust automatic brightness levels... except you know someone at Google working on Android project?

[Q] Galaxy Note Edge Tmobile. Brightness Issue/Overheating

Just got my Note Edge 2 days ago and when comparing the screen brightness (at max/no auto) it is much dimmer than our note 4. now I am not talking about the super bright setting that occurs when its on auto and outside but instead indoors. I also have been seeing a message in the display brightness settings "UNABLE TO INCREASE THE BRIGHTNESS FURTHER. THE DEVICE IS OVERHEATING" Could this be due to a faulty battery or something else? This is my only complaint with this phone but its a big one especially if i'm receiving this message. Should I return to Tmobile or is it most likely a software glitch. It is very cold where I am at so it has not been out in the sun or plugged in too long. minor use has led to this overheating message usually only seen in the summertime when in the car too long

why you need turn on full brightness? I only use brightness like 20% on that slider. it also save battery.
Sent from my SM-N915T using XDA Free mobile app

I typically enjoy and have always used max brightness and even if i didn't this issue probably shouldn't be happening. It's the fact that i think something is wrong with my new phone already. I want to make sure by asking questions

Yes something is wrong if you're not gaming intensely or something like that. It should never overheat just from full brightness I have the T-Mobile one and I use max brightness all day no problems.

Guys the samsung NoteEdge on lollipop has that issue. Basically you can't switch auto brightness fully off it will control your brightness even if uncheck the box. After weeks of searching and trying I found a kind of solution because I love to see my screen in all his power and brightness. Solution is call "screen filter" can be found in the play store for free. Set the brightness at 100% and switch it on. You'll see the difference.

Sensor next to front cam?

Hi guys,
Noticed a very interesting thing today: suddenly a white light started to pulse next to the front cam every time I was tilting the phone. It was quick 3-4 pulses with strict intervals as if a sensor was working. It didn't pulse when phone was in a fixed position, only when tilting, in all apps.
A reboot fixed this, but I wonder if there is any sensor there that activated because of something? Never experienced this before!
Any thoughts what it can be? Thx.

Sounds like proximity sensor to me.

Thanks. I also thought so but the phone didn't turn off the screen when I was placing my finger on that sensor. The proximity sensor should turn the screen off as far as I am aware. Maybe a glitch after doing a video call via Viber?

A glitch with viber thats causing excessive proximity sensor usage. It will eventually burn the pixels around that area like the other post posted today.

Hoe bright is it?
Normally it could blink during SOT and with that duty cycle it will outlast many of the other screen pixels.
Or is there something I'm missing???
Are it's pixels IR?

Who's a hoe?
Probably much ado about nothing. But I can't test it. , The only thing that came to mind was screen being full brightness and proximity sensor being on for hours causing this. But just a hunch .

Even at full brightness because it's flashing, it's duty cycle is less than the surrounding pixels plus it will "flash" by darkening its pixels depending on screen color.
If it has specialized IR emitters I could see that happening maybe; if there's a design or manufacturing flaw.
Because it's flashing visible light it would be hard to use a cam to detect IR... which is how I normally check IR emitters.

Interesting. Maybe it uses IR diodes?
If it doesn't display when it's active maybe that's why some think it's "burnt out"?
Lol, until someone mentioned the flashing circle I never noticed it.

I don't know.
I've read that they replaced all the sensors with the front camera, and that′s one of the battery killer since a few were completely passive like the ambiant light one, that's now active.
When a passive sensor needs no electricity to operate, an active needs to, and the camera can't work passively so it drains battery.
They advised to turn off all the features that use the front camera as a sensor like the auto brightness, smart stay (and also what can use the accelerometer like smart alert and raise to turn on the screen), etc. to avoid the process Android System to take to much battery.

Even passive sensors use some current although it may be in the microamps.
Autobrightness is a trash apk anyway.
Seems highly unlikely that the whole cam be used for these functions if at all.

Not sure if anyone told you this sorry haven't had time to read the thread but I would suggest avoiding viber calls on this phone. The proximity sensor is damaging the screen when on viber. It seems viber is accessing the sensor too aggressively.

You know this is most likely a digital circuit; a fixed voltage of an either high or low value... those values are fixed and don't change. Even firmware can't alter that let alone apks. Duty cycle rate/length maybe.
This urban rumor about the proximity sensor causing screen damage has been around since at least 2015, long before OLED screens.
A Google search yielded nothing except this:

My opinions.
There certainly are long standing Samsung issues that span more then one generation of phones. The proximity sensor trashing the screen doesn't appear to exist at all. If anything it conserves screen life.
Auto brightness was always twitchy even on my S4+.
Auto brightness was never truly adaptive... and still isn't. Lol, all it does is give me a headache and waste resources.
The other thing is I always try to avoid using my phones in direct sunlight. Very rarely do I ever go past 65% brightness.
Direct sunlight+high ambient temperature+high power consumption can really overheat a phone fast.
Even worse...
Auto brightness on+charging+sunlight+accidental screen turn on that's not noticed, can fry a phone in a few minutes. Real easy to do in the car... been there.

Thanks, i never thought about that so it's a very valuable information.
Just in case if it can be useful :
A few years ago I found an app called Underburn which is a complete new approach about adaptive brightness.
https://play.google.com/store/apps/details?id=com.out386.underburn
Instead of adjusting the screen brightness from the ambient light, it set it according of the amount of white pixels displayed on screen to avoid binding you, and it doesn't care about sunlight.
The more white is displayed, the more it will dim the screen (by reducing the screen brightness, not by applying a filter ; even if there's also a setting for that if its too bright for you even at the minimum level) by the amount of your choosing.
It can play a role to save battery too somehow.

Thank you
I'll take a look at it. I'm running on dark mode but since it's Pie it's not native to all apps like Gmail which burns my eyes out.
*I'm playing with it. It will run on Pie. It takes some time to set up but definitely has potential.
Haven't been able to fairly gauge it's configured battery usage.
