Increase display brightness to the max? - Galaxy S 4 Q&A, Help & Troubleshooting

You know with the last firmware we got a limitation on the maximum brightnes due to "solving the overheating problem"... Is there any way to revert it back to a very bright screen? It's very bad right now to see this awesome display rouined....

Configure Automatic brightness

Hi, does anybody know if there any possibility to configure min/max level of automatic brightness. All I need is to increase the min brightness (it's too dark for me) - is there any app or some kind of "registry" hack for that?
Hmmm... the minimum brightness on mine is too bright, IMO. Laying in bed with the lights off, it's almost blinding...

Try to see anything on a screen in a room, filled by a sunlight. Is it still too bright? I mostly use this device while sunlight, not in bed
I find both cases annoying.

Bump.... Anyone able to figure out how to do this?
Now Froyo has improved the auto brightness somewhat we really need a hack to increase the minimum brightness or just increase the auto brightness level by say 2 notches. Its always just a bit darker than I want it.

Couldn't agree more.
New autobrightness is pretty much perfect for me during the day! I haven't tested it at night yet though.

Heating when taking pictures?

why does cpu temp reach nearly 60 degrees when i only use camera to take photos for minutes?
is it ok?
I read a chinese news reported that it is vulnerable to damage by overheating in darkness cuz it has to raise voltages to keep white balance.
discuss.

about dpi

For good battery life what amount dpi should I set? I know the default dpi for note 3 is 480! And if I want to increase my battery life should I reduce the dpi?
Need to know about mobile screen dpi

I can only say, DPI has nothing to do with your battery life.
It is your phone usage, installed apps, running in bacground apps which will affect the most.
If I set lower DPI (Dot Per Inchi) so my device regulation goes low, whenever regulation is low, isn't battery consume lower energy?

No, your phone display uses still same amount of energy to display. The only change appears in objects size on your display.

CPU utilisation with auto-rotate on is high

Hi,
I've tried monitoring CPU frequency with auto rotate on and off and noticed that with auto-rotate on if that phone is being moved about then the CPU cores all ramp up a bit.
To re-create:
use on-screen cpu frequency monitor
*shake* the phone in front of you whilst watching CPU frequency
with phone locked portrait I have 4 small + 1 big at 384 Mhz.
with auto rotate I get 4 small cores at 1500 and 2 big core at 1.5-1.8
The only record I can find of this kind of bug online is some entries in Google's bug databases for the Nexus S back in 2013-2014.
What does this mean? well, assuming you don't have rock-steady hands, or perhaps you want to use your phone in a dash-clamp in the car, this random CPU spiking with drain the battery and heat up the phone for no reason!
I've been able to get a notable increase in battery and reduced heat output of my phone by leaving rotate off unless I really need it, but this is clearly an issue that needs to resolved.
Well the "auto rotation" is really fast in this phone, could it be because of this?
it could be related yes, almost like they ramp up the cpu on ANY movement so that the rotation occurs without stalling due to lack of immediately available cpu power
seems excessive though, and definitely dents battery somewhat. I've filed a report with Sony by email and the forum now. see what happens .
Yes but If I compare this rotation speed with other phones (like my ultra fast nexus 5), this rotation speed is awesome, one of the best "performance advantages" of this phone
Anyway, maybe this is a "real bug", and the "fast auto rotation" in the Z5C just exists thanks to the sensor quality and will continue rotating fast even at lower cpu clock speed.
Who knows...
I'm on xzu and in my experience, this is clearly how Lollipop does it. Don't know if it's originally coded by Google or Sony, but i actually prefer the old one on Kitkat. The new one is overly sensitive. Even if i just slightly nudge the phone to the side it changes the rotation.
This isn't a bug at all but a feature introduced by Sony.
When you are rotating the phone the cpu is boosted during a little amount of time.
You can see that by analyzing the code.
This can be turned off easely.

A cpu-frequency increase doesn't necessarily mean a cpu-usage increase. This behaviour is perfectly normal and may prevent sluggishness.

Lowest Resolution For S4

Yup, you read that right, lol. I'm going to install the app that downscales the screen resolution but I want to go lower then 720p if possible, for maximum power saving.
I'll be installing Linage OS 11 over the weekend.
I use the phone for GPS/Waze and to make calls. I've always hated the fact that it was full HD as I know from using 720p phones that there is no visible difference at all! Most importantly, I want to save battery life as the screen is constantly on for navigation.
What is the lowest resolution it can support without getting distorted? its a 5.1" screen so odd screen size. Would 480 x 800 work? If so, what DPI would that be?
Thanks!
480 X 854 is what I'm using for some games.
Any lower and you will have black bars around the screen.
Do note that not all apps downscale well. I also considered using the device in a permanent state of low resolution, but some apps simply did not look good.
Also, I'm not really sure if there is any big battery gain from this; I simply did it for the performance gain in games.
Thanks for the reply.
Theoretically wouldn't it be using double the CPU (thus more battery) to generate double the pixels at all times?

By that logic, my OnePlus 5 should have double the battery life of the S8, because it has half resolution.
In reality they are fairly close in regards to battery life. Or so reviewers say. Battery drain tests also show the flagships not that far apart.
Most power is consumed by the screen itself, not the CPU.
Sorry I meant using double the CPU/SoC in the processing of pixels, not double battery usage.
Example, to process all information at 1080p the SoC will use 10% of its power to process it, however at less then 720p it would use 5%? In theory anyway.
I think.... Lol.

As I said, the screen itself uses the most battery. Doesn't matter if it's 4K or HD.
Yes, higher resolution requires more processing power, but it's negligible.
You might as well reduce the CPU frequency to about 1 GHz and you will have the same result.
It won't make a huge impact on the battery life. Not the one you expect at least.
Or you can simply test it yourself. The app I'm using is called Screen Shift.
See if
