Hi,
just recently updated to the stock/official V12A (euro) update and while I must say that everything seems to run smoother and faster, I noticed poorer video quality capture now compared to the froyo performance. I am noticing maybe only 24fps while recording in FHD with video stabilization on and the problem worsens when panning around.
anyone else have this problem? I might try out one of the customs roms if this problem does not exist on them
thanks
I haven't played much with the camera yet with GB but the decrease in image quality is probably due to the use of the image stabilisation.
Because the O3D doesn't have a hardware stabilizer (I can't think of any phone that has one) it crops the image a bit so it can compensate for the shaking by moving the cropped frame within the full image and when the video is done it blows it up back to 1080p.
If you want to compare the image quality to Froyo builds you should disable the stabilizer option.

my concern is not much on the actual quality per se
it's the framerate that has gotten worse since the update (where framerate was nothing to brag about on froyo to begin with )
Thanks
Hello! Was wondering if there was a way to change the resolution of the S6 from QHD down to 1080p. I've found the Nomone Resolution Changer, but I was wondering if there was a more trustworthy way about getting the resolution to get to 1080p. Long shot, but still! Recommendations, please?

Actually I was wondering the same thing until I remembered the fact it has a small battery and a 5.1" screen that really doesn't need the QHD resolution with such a small battery + screen
There are some apps available to change the DPI, i know that skydragon roms come pre baked with a DPI changer, but this will require root.

But that's not how it works. The phone will still have the same qHD screen, and will still have the same amount of pixels, and require the same amount of power. You're basically just changing the DPI to make everything larger, using 4 pixels to display what 1 used to.

No he actually wants to change the proper resolution, not DPI.
Less resolution = Less processing power required = Less battery spent.
That being said.. OP no there isn't a way

Right, that's what I meant. You can't change the DPI (which would what he'd be doing) and have it magically change the physical number of pixels used.
No that's not what he's asking. He's asking this much like a TV. Instead of having it be QHD he wants it to display in 1080.
It's a clever way of thinking but that wouldn't help really. It'll still have the super pretty screen just everything would be smaller. Even if there was a way

But that's the point: Even if you wanted to display in 1080, you still have the same amount of physical pixels in the screen, and the same amount of power needed to light them up. Unless, of course, you wanted to only use 1920x1080 pixels, at which point only 25% of the display would actually be lit up.

You're missing the point.
First of all, lowering the resolution would make everything appear larger. You have to lower the DPI setting in build.prop to scale things back down to the same size (or lower).
Secondly, lowering the output resolution will save battery power and increase performance because the CPU and GPU are working less. This is fact and just how computers work (the screen is not the only power draw in a phone). The amount of physical pixels in the screen is irrelevant because that will draw the same amount of power regardless of what the resolution is. (However, since the is an AMOLED screen, it will draw less power when displaying blacks due to the nature of the technology. Not that this has anything to do with the resolution discussion.)
Thirdly, the amount of power you will be saying varies. Mostly you will gain performance and power-savings while playing 3D (rendered) games. The GPU will be able to perform at a higher framerate as well as save you power. This is tested and true, although some applications will be glitchy due to poor coding. The amount of savings while on normal screens is subject to the efficiency of the SoC. I am not sire much will be gained here. Performance in these screens is said to be slightly increased, although I believe this phone probably has snappy speeds already.
Lastly, if you do this there may be a visual issue that could get on your nerves. Since you are altering the 1:1 resolution of the pixels, a blur will naturally occur. Since the screen is relatively small for the amount of pixels in it, the blur will be minimal and you will hardly notice after your eyes adjust to it.
Using Resolution Changer Pro (free app) you can set res to 1080 and dpi to 480 for a significant improvement in gaming performance. (phone doesnt heat up like frying pan anymore)
Difference in quality is completely unboticable.

Yes after resolution changed, everything go smoother

Hello Thoth33,
I used Resolution Changer Pro, but it didn't change the resolution!
What do I do wrong? I use Android 6.0 beta on my Galaxy S6 (SM-G920F).
It even tells me that it gets root access!

Solved the problem via Android Terminal Emulator!!
i changed the resolution on my Galaxy S6 Active from QHD to just HD!! Did some graphics benchmarks and the results are more than 2 times those of QHD.
Oh, and I did this without ROOT.

How to do it without root?

You can do it via adb.
These are the 2 commands for both screen resolution and dpi
adb shell wm density (insert dpi here)
adb shell wm size (insert resolution here) && adb reboot
The reason for using both commands is that you have to use the correct dpi with your desired resolution and screen size, so that the icons and UI is neither too large nor too small, otherwise, the UI will crash
For example,
For Galaxy S6,
If you want 1080p, you have to choose 480 dpi as that is the correct dpi for a 5.1 Inch diaplay.
If you want to go back to QHD, just repeat the same commands with your stock dpi and resolution, which are
640 dpi
1440x2560 resolution && adb reboot
I did it via adb because currently there is no root for the S6 Active.
Hi,
Wich resolution you use ? (1080P/1440P)
And why ?
Please say if you have an S8 or S8+.
It would be Better if you are on Oreo (Samsung have working on it in Oreo for less difference on both resolution )
I use 1080p cant see the difference im on s8

1440P oreo. can see the diffirence in resolution, but not in the battery

Yes im on Oreo
1440p for sure. If I need to last battery like for a long time (and forget my powerbank) i´ll just probably use battery saver - 720p. Don´t see reason why use 1080p anyway...
Problems with facebook on 720p. Pictures and videos are cropped.
I have seen big difference in smoothness .
For compared in fhd+ my s8 is more fast than mate 9 of my wife and In qhd+ the mate 9 win .
There's minimal battery difference between running it in fullhd+ and qhd+, the only way you would find some battery savings is if you play games a lot. I'm on oreo beta exynos
1440p. I'd rather it look better than get an extra 15 minutes of battery life
Wow...I can't believe people aren't using the full quality of the screen. You do realise the battery difference is negligible right? Whether you use FHD or QHD+, the display is still having to power up all the pixels. You save maybe 15 minutes of battery, nothing more, by using FHD.
Personally I can definitely see the difference in visual quality.

Yes agree with you but in term of performance the difference are no negligible.
Wtf are you guys talking about? The gpu is always running and rendering for full resolution. From what I understand, this "Screen resolution" setting is nothing like the "Screen resolution that you observe in Windows OS...". The difference is just the percieved resolution (BY APPS!!!) similar to what is done on MacOS..

Sorry but I don't agreed with you .
The operation of the gpu is the same as that on video games. If you play in FHD or QHD the request for power is not the same and you need a gpu/cpu more powerful .
A pixel is a pixel is a pixel. The higher the resolution, the "smaller" they seem.... You are still powering on all the pixels regardless ofthe resolution... The resolution, as it was mentioned before, is for the apps to use for scaling (if you ever develop anything for Android, read this article https://developer.android.com/guide/practices/screens_support.html)
Resolution has little to no effect on battery, everyone stop crying about it...
1440p because I wasn't raised in a barn.
Haha! I just had to put that. I do use it but I have no good reason.
I have to agree with an earlier post that the higher resolution would impact performance.
I tried the highest resolution and I agree, everything looks much better and has close to 0 impact on battery life (if that's your thing) but I did notice a significant drop in performance.
That being said on 1080 there 0 lag, while on the higher resolution there's lag even in basic apps like messaging or contacts.
But that's my experience.
I don't really care that much about battery life on the s8 as it always got me through a whole day of usage, regardless of the settings, but I do care about performance.
I am 99% sure changing the resolution has an impact on gpu.
It's correct that I doesn't impact display power consumption but the gpu has to render more, so it will impact gpu performance.
Just my 2cents
Hey, All...
Has anyone noticed any performance or functional differences between 1:1, 4:3 or full screen mode on the stock camera.
I'm trying to see if either has better photo quality output.
I have been comparing the three and I believe I notice some slight difference in quality. I'm not sure if this can knowledge help in quest to make sure that the camera performs as best as possible...
I noticed a full screen pic was a bit grainy in low light situations. I usually stick with 1:1 myself. On latest 9.5.7
4:3 is likely the real aspect ratio of the sensor. Use that
