Hi. Is anyone else annoyed by the high illumination of the screen whilst driving, especially at night? Does anyone know if there is a fix out there for it?
Apart from keeping the screen closed..! like to have it open so I can see who is calling, setting it so the screen is at minimum illumination and shuts itself off after a minute whilst on power, but it's still too bright and well the next setting down ain't much help.
Great toy, but it's really starting to annoy me. Any advice, greatly appreciated.
Cheers
You could always wear some sunglasses :lol: or put it in a dark plastic ziplock baggie...hehe

sounds like u need:
1. fag lighter charger to prevent shutoff
2. a dark theme to reduce the brightness
- edit -
I have the charger. That's fine, what I meant was I had set the settings to dim the screen after a minute (that's the minimum you can select whilst on charge), not that the unit was switching off. Sorry for confusion. My issue is the difference between the two lowest levels of brightness. With one you can see the screen, with the other you can't. What's this dark theme you mentioned? Is it between the two?
What would be great would be a night level similar to what TomTom offer on their gadgets.
Alternately you can use a profile management program such as pocketzenphone or the still under development phonealarm and set a profile for night driving with reduced screen brightness.
Kind Regards
Hey guys,
do you think it's possible to wirte a program which automatically can change the backlight according to the actual daylight condition.
Maybe it is possible to start the program when you wake up your device. then the program turns on the built in (front) camera for about a second or maybe more. The camera "checks" out the light intensity. If its very bright the backlight condition is set to the max.
his is only a idea. I'm thinking of it because for example today it's a very sunny and i can almost read nothing on the display of my touch cruise!!
What do you think about it?
greetings
any idea?
Or does any software like this exist?
Maybe the guy who wrote this program below could be of assistance:

Well, it doesn't have to be so hard...
All we need is a small service that reads from a file the approximate sunrise-sunset time and alters the brightness accordingly. If anyone has the time, he can additionally take advantage of the current time zone and calculate those limits automatically all year long!
Destinator 7 does the exact same think by turning night colors on and off. It is actually better than a build in brightness sensor because it never fails!
Nevermind...did not read the question thououghly
Yeah good ideas,
but a time sceduled scenery has also disadvanteges. When its clowdy outside it causes unnecessary battery consumption.

I come from a rather sunny country (greece) so I really missed this!
Anyway, those PDAs have actually very low brightness screens. In a bright day you cant actually see anything. On the other hand, I have yet to see a rainy/cloudy day that requires a reduction to the maximum brightness level. Overall I think that a time scheduled solution should be the best solution for no sensor-equipped devices.

I second that! Even though I'm not from Greece but it's never too bright during the day. Right now my solution is to map the camera button to backlight so I can change it quickly.
Changing the brightness according to the time of day would not be as helpful as changing it according to the ambient light level. If you walk inside a dimly lit building during the day, you don't need the backlight to be as bright as if you were outside. Also, even outside, a cloudy day can be considerably dimmer than a sunny day.

I totally agree, but given the fact that there is no ambient light sensor in our devices I dont think that we can do any better. Two scales, one for day and one for night and we are OK for most cases. Yes, as you point out this strategy fails but it is better than:
1. No brightness change at all
2. Manual changes.

Thats the crux. Some devices especially the newer ones have a camera on the front. I'm no photo-expert but i think every camera is a "ambient light sensor".
The camera also reacts on different light conditions. You can see this by turning on the fps function. But i agree that it would be a lot of work.
Maybe we have to wait till more people and programmers own htcs with such bad displays like the polaris.
Titan Photo Sensor
I found myself thinking about this auto-backlight topic on my way home tonight after a long trip using my 8600 as a GPS. The screen went from being a clearly-visible screen during the day portion of the trip to a flashlight in my eyes at night. While I knew I could adjust the backlighting manually, I didn't want to mess with it while driving. Also, living in Arizona, I can barely make out the screen when in daylight unless the screen is on maximum brightness, but max brightness is horrible on battery life, so I would rather not set it to that by default.
Anyway, the Titan has a photo sensor on the keyboard which is used to determine dim lighting conditions and automatically illuminate the keyboard. I'm not sure if the exact lighting value being detected by the photo sensor can be read, but if it can be, then it should be relatively easy to write an application that would automatically adjust the backlight setting whenever the keyboard is slid open.
The application could both use location-based sunrise/sunset algorithms to set the default backlight value based on time of day, and also allow the setting to be overridden momentarily (perhaps only until the screen is turned off again) by opening the keyboard and sampling the ambient lighting conditions.
who knows how to turn off the light sensor? should that be always at maximum
Is it that thing that make my screen going dark sometimes and then bright again ?
I thought it was a bug in Android about the screen light management...
I'm very interested in turning it off me too.
I didn't look very hard, but from what I can see, you can't.

Yes, it does just that hinders and tired eyes!
The above sentence makes absolutely no sense.
sorry,I mean ,that light sensor kills my eyes
Still it makes no sense at all!

Ok guys, we all agree that his english is horrible, but it is understandable that he is saying that the changing / blinking of light, all the time, is not confortable for eyes.
I admit... for once, I understand his words...

Turn the brightness down if it is uncomfortable? The reason why it changes automatically is to adjust to the amount of light in a given place. Otherwise, you'd have to constantly change the brightness yourself in order for the screen to be visible in all conditions.
Yes, I think we all know what is that function for, that's not the point.
The problem is that, in the same place with the same light, if, for example, your head make a shadow over or if you put your finger on the little hole up right the phone, the light of the screen will change as if you where in a place darker.
So according how you move the phone or hold it, your eyes will have to accomodate very often and it's very uncomfortable.
Maybe covering permanently that little hole will be the solution... but I would prefer just to turn it off.
Covering it permanently will also permanently place the backlight in the darkest mode. Personally I like this feature, once you know it's there it doesn't give a 'wth is happening'-feeling anymore and I believe it saves battery (no need for full brightness in dark places). Also for me it kinda gives that viewing-on-paper feeling, the device is quite okay in maintaining a balance between minimum visibility and overlighted eye-blasting power
Though yes an off-feature would be welcome sometimes ^_^
I would also Love to Disable this sensor.. More Brightness! MORE more more i tell ya! lol
Hi Guys,
With the torch app you can increase the light power ? (high voltage?) is it possible to decrease it too?
I take pictures and the flash is far too powerful and would like a setting or percentage to decrease it?
If its possible per-se I'll look into the code and have a play?
Cheers, Sarkie

Hmm, the flash is never too powerful. What you want is to decrease your camera expose time or the iso-sensitivity.
In stock camera app, you have the settings button, choose exposure -1 or -2. You'll get what you hope for.
Today, for the first time, I've noticed that the N1 is adjusting the flash intensity. It seems to have 3 or 4 different levels, and while taking a photo, at the time of the auto focus, the led comes on at various intensities, and the best one is chosen.
I have never noticed it before (but I don't take many pictures.
Maybe it's a 2.2.1 feature. I am not sure.
Hi everyone
I want to share a workaround to all of us who owns a defective S5
Symptom: You unlock your phone and it doesn't show anything. Actually, the phone is working. Capacitive buttons light up and you may heard some activity in the phone
Your phone has a defective screen. There are a lot S5 which have this problem, according to several forums. After several tries, unlock and lock over and over, the screen light up and you are able to use your phone. The problem is when you receive a call and you want to know who is calling you, the screen doesn't illuminate and you won’t be able to know who is.
Here's a workaround which makes your powerful S5 usable and take out from your drawer.
Solution:
The more effective way to fix it is: change defective screen! But sometimes it could cost as much as a new phone, or simply you can't afford it, and it's better to change your phone instead, and you put your S5 in a drawer.
The technical explanation of this problem is: Screen doesn't receive enough electrical current at low brightness levels (maybe the flex is defective, get old, etc)
Most probably the wake up problem exist together with screen flicker at low brightness levels
The wake up problem rises up more in dark environment, when light sensor make low bright screen
The lock screen light up screen, with a dim effect: when you lock the phone, it slowly turn screen off, and when you unlock, it make and effect of dim screen.
When you are is in dark environment, the effect is very slow, preventing the screen illuminate because the technical problem explained before.
When you are in very light environment, you lock screen and sensor light make the screen very brilliant and chances are you defective phone wakes up correctly.
We can use an app which give us complete control over brightness subsystem. I use an app called Velis AutoBrightness:
Once installed from Play Store, it shows a Setting Wizard. Follow the instructions. Below are some notes
• 1/7: Welcome Screen
• 2/7: How bright... Most probably is your phone always have flicker in low brightness. Choose "AMOLED" or "AMOLED bright". By the way choosing any one of those cure always minimum brightness failure!
• 3/7: Choose High sensitivity
• 4/7: On, if you want additional brightness when charging. Irrelevant for this thead. Choose your favorite setting
• 5/7: Same of 4/7
• 6/7: Choose enable: That enable the app
• 7/7: Some additional notes: Press Done
Now important settings: go to Menu > Settings > General: Settings Mode > Advanced
Service Activation settings:
• Disable system handler > ON: When you use Power saving mode, you surely noted screen flicker, which is very annoying, and make unusable power saving mode. By set this ON: Android doesn't set screen too dim; instead Velis have a minimum of brightness set by Wizard 2/7. (Surely you find out that you avoid screen flicker, by setting autobrightness off and slider in 8-10%)
Sensors settings:
• Screen-on sensor value override: Set this value to 30000. Read below this post if you want technical explanation of this setting
After you establish these settings, you'll be able to unlock your phone all the time!
This is the trick: When you unlock your phone, you'll note that the screen is very bright (because Screen-on to 30000) and quickly adjust to the environment light. The failure is that electrical current to screen is defective, and when exterior light is dark, the screen make a dim effect and doesn't light up.
Note to Marshmallow users:
• This app make use of Screen overlay permisions: And marshmallow is very restrict with this kind of app. This is specially true when you are installing an app. All you have to do is deactivate the app in notification screen: press "OFF" button, adjust system brightness upper enough to not flicker the screen, install your app, and activate Velis Autobrightness again
• Because of Doze mode, wake up from this mode may avoid your screen light up, the first time you use your phone. Let 10-15 seconds your phone wake up, lock again, and unlock again, and velis will make its work!
I hope this post make your smartphone usable. I barely apply this trick to two phones, but I think this is a good workaround!
I used this app & the flickering is still available
What worked for me is downgrading the firmware on my g900f all the way back to Android 4.0. My phone came with version 5.0 and I noticed the problem only after I kept installing samsung's system updates. Will report if the problem starts up again but I'm running rooted and running nougat just fine so I don't see a reason to keep upgrading the firmware.
Edit: nevermind, this didn't work

Does anyone know for sure if it's the flex cable or some capacitors? I notice only the lower half of my screen flickers.. I bet there's a simple electrical fix for it instead of replacing the whoooole display

Hello,
Have you change jour battery? If it s old it could cause some issues...
But try to buy a genuine one, I think that your battery must be old now.
Bye

I noticed that screen only flickers at low brightness when using Boeffla kernel for LOS14 and others based on it.
No issue for the same device with LOS or Stock based kernels.

+1 to that , i even went back to stock and the screen flicker appeared and such issues are well known already with samsung amoled panels back in 2014-even some panels from 2018 . So def not kernel related.
I was using los 15.1 and this problem got worse. The phone was barely usable as mentioned by the op. In my case, the screen would start flickering below 60%. Then I switched back to stock marshmallow. I noticed that 100% brightness in los 15.1 is actually only about 70% in the stock rom.
I have been using the phone at 80% brightness for some weeks now and the problem has significantly reduced. But not completely gone, it's much much better. Also, you might want to avoid using dark wallpapers.
