How to change Screen density - Galaxy S6 Edge Q&A, Help & Troubleshooting

Hi everyone!
I'm triyng to improve my s6 Edge performance and hopefully also battery, decreasing the density of the screen trough adb. Commands I'm using are:
adb shell
wm size 1080x1920
wm density 480
But I think something is going wrong because when I have this resolution I can't manage to trigger the edge people on the right side, but only on the left side. I've also tried to change density but without results. Hope someone can help because GPU improvements are really remarkable as you can see here http://www.xda-developers.com/the-z5-premiums-resolution-is-not-always-4k-and-thats-a-good-thing/

no one can help me?

[Q] i want to change my lcd density to 200 (ish) but want to resize the dialer too

hi guys..
i have seen a few posts on the SGS side of things about resizing the dialer / camera etc... correctly when the LCD denisty is changed to a lower than standard figure..
is there a way of these apps "ignoring" the LCD density values set in the build.prop files?
just thinking.....

This ROM has a modified camera app for 200 dpi: http://forum.xda-developers.com/showthread.php?t=1149713
Just extract it from SkyROM and replace yours via adb or root explorer...

[Q] want to change screen DPI

hi all i want to know that what is the benefit of changing dpi od screen. i checked lcd density modder but i m afraid will it help in savind battry of yes then how??
No it does not help you save battery. It lets you see more things at once by making everything smaller. It is a "high res" effect.

[Q] Decrease Resolution for Gaming?

Hello Tablet Z community,
This is my first post in this devices forums since getting mine last week. It's a great device, love it, etc.
I've never owned an Android device with a screen resolution this high so I've yet to encounter this problem - some of my games (specifically the emulator PPSSPP) have relatively low framerates (compared to my less powerful Samsung P6810 @ 800x1280). I know with computers in particular it's trivially easy to change resolutions in games/the OS, especially to increase FPS but I've never seen a method to do this on Android and Google searches turn up people mentioning device resolution without changing them.
Does anyone know if it's possible to, ideally, force a different resolution for a particular application? A less than ideal solution would be a system wide change but I would be willing to endure temporarily to increase FPS.
Any advice and suggestions would be greatly appreciated
I would be interested to know about this, iv just loaded ppsspp however havent been able to play any of the playable games listed, I did see a few videos of the xperia z playing well, however that has the same resolution and specs.

This is very different, setting the DPI to a non-stock value just resizes the userspace, the resolution is fixed and unchangeable as the OP is thinking. Compared to a Windows PC where you can change the resolution, in Android you only have the ability to change the dpi, which states how large the pixel-to-screen size is. A smaller number indicates a smaller pixel-to-screen size, meaning the information shown on screen is sized for a laeger screen (making it smaller, since the screen is a fixed size). And a larger number has the reverse effect. Android UI guidelines set the optimal dpi for resolution vs. screen size, to mainain a similar experience across devices (similarly sized icons and fonts, etc). Again, this has nothing to do with adjusting the physical resolution of the device, which (to my knowledge) is not possible in Android.

Heh. Thanks for the schooling, but it was unnecessary, I didn't just fall off a turnip truck.
Thanks for the replies guys, at least now I know for sure..

[WARNING] Changing LCD density and then resolution

I just thought I would give everyone a warning about changing LCD density with "adb shell wm density XXX"
(only applies to us non-rooted users -- rooted users can edit build.prop on the fly)
If you change the density, and then decide to check out the other resolutions like 720p and 1080p, it will fully erase your set density and return to stock resolution, even if you change the resolution back to stock (WQHD)
I myself didnt know this. I thought it would keep the resolution and recalculate the density, or reduce / increase the density based on the difference between WQHD. This is not the case.
So for those who set a custom density, DONT CHANGE RESOLUTION!

Android 9: Space/ Padding below status bar after changing screen resolution (Sam A40)

Hi,
I hope this is the correct forum for my concern. I own a Samsung A40 device and I'm very happy with it.
For performance and battery life I changed by screen resolution from 1080 x 2340 to 540 x 1170, set the density from 439 to 220 and removed the rounded corners via ADB from PC:
Code:
adb shell wm size 540x1170
adb shell wm density 220
adb shell settings put secure sysui_rounded_size 0
And it works pretty well and I'm happy with it- it's enough resolution for me. But one little thing annoys me- With the lower screen resolution the space/ padding below the status/ notification bar in every normal app is too large and it looks ugly. The A40 has a very small notch in the middle of the status bar and the empty space is below the notch. Is there a way to change it? I have uploaded a image showing a screen shot, I painted the notch in black and the red space I don't want to have:

Thank you in advance,
