DPI/Resolution Changer Program NO ROOT NEEDED

I got tired of messing around with DPI/Resolution combinations by typing the adb commands every time. So I wrote a nice little batch file that should work for any phone running 4.3 or greater. It doesn't require installation of the android SDK or even ADB - all files necessary are contained in the 7z file. Just run the file and follow the prompts - everything is taken care of for you, including finding the default values for your device in case you mess things up. The program also fetches your current DPI and resolution so you don't have to go digging for it in build.prop or dumpsys to see where you are presently.
Download here goo.gl/YTsHQp
I used to run unrooted on my Verizon GN4 N910V. A resolution at 1080x1920 with 360 DPI forces *some* apps to run in tablet mode, and gives a very large increase in screen real estate. I can live with the small dialer problems (can't be fixed without rooting/xposed as far as I know) and change my launcher, in exchange for a cooler running phone (average 7 degrees cooler under benchmark load) that uses slightly less power (average +27 minutes per charge according to Gsam), scores an increase of 16% in AnTuTu (52077 at 1080p and 45085 at 1440p), and has WAY more screen real estate. I don't notice the difference in resolution at all, even if I'm trying to.
Note that turning animation scale to a value greater than zero may be required for running some launchers nicely while screen scaling is turned on.
The included HOWTO file gives instructions and outlines some acceptable whole number 9:16 ratios and DPI settings for stock DPI ratios - and outlines how to calculate the numbers yourself. Open source on the code, modify, redistribute, etc - just give attribution to zediiiii.

I'm not sure i understand how this improves performance when you are scaling down the objects on the screen.

How can I change the DPI/Resolution per application?

You can't without root.
This program works well. I have noticed some issues when running at 1080p using the DPI provided in the readme. Certain things (boots screen, movies in games) won't play because, I'm assuming, it is relying on the build.prop but the resolution defined in that file is not accurate. It's a minor inconvenience in light of the fact that running at 1080p and with a heavy deploy it getting me nearly 7 hours sot on lollipop.

Nice job @zediiiii.
I tried it on a Galaxy S4 with KitKat and a Galaxy Note 4 with Lolipop. On both devices I just tried to lower the resolution while keeping the stock DPI to resolution ratio, the goal being to save some battery. On the GS4 it definitely reduced heat while playing games and increased the Antutu score. Unfortunately it also broke the stock keyboard and camera. I didn't see any problems with 3rd party apps. On the Note 4 I didn't test as much, but the stock keyboard was also broken.

My understanding is that driving less pixels per square inch (PPI - I incorrectly used DPI in my program...) means less bandwidth through the graphics processor and thus more headroom. So you either slightly increase performance or slightly save on power - depending on how you use your phone.
I use it for the slight power save, because I can't tell the difference between 500 PPI and 300 PPI, and so I can trick apps into thinking I'm using a tablet on my GN4.

When you say broke the stock keyboard, you mean that it's scaled incorrectly and far too big on your screen? How did the other stock apps fair? In my experience, if you stick with the correct resolution to PPI (DPI is the wrong acronym; I was kindly corrected by a fellow programmer) ratio, the stock apps continue to work as expected. Stock apps crash for me when the ratio is lower than it was before, and simply get smaller on the screen when the ratio is higher than before. If stock apps are crashing, you could try incrementally raising or lowering your DPI and checking for results. I made the program so that this was easy to do incrementally for this very reason.

Yes, exactly, sorry I wasn't more clear. On the GS4 i tried multiple resolution and DPI combos, always keeping the stock ratio. The stock keyboard didn't scale properly with anything other than the default settings. On the Note 4 I only tested with 1080x1920 and 480 dpi, and saw the same scaling issue with the stock keyboard. This is not the fault of the script, so it's not a complaint. It's just a note to warn others that if you want to tweak these settings on a Samsung phone, then you may need to use a 3rd party keyboard.
On the GS4, some of the control buttons were missing in the stock camera app, but the Note 4 didn't have that issue. I didn't see any crashing on either device, perhaps because I was always keeping the stock ratio.

Thanks for the good information. My guess is that anything touched by Samsung, eg, the dialer, the home screen, the camera etc will not scale correctly and may be buggy even with the sam PPI:RES ratio. Oh how I miss Xposed (which I think @locolbd knows is the best way to change ppi per app if you have root, among other things)... Not hopeful for a real root solution for VZW GN4 at this point.

not sure if i'm going blind where where is the script located or was it taken out?

Because I mentioned my lack of hope for root on the N910V earlier - if anyone hasn't noticed, there is a great guide for permanent root (start here, it links everything for 6.0.1 upgrade) on the N910V Verizon Galaxy Note 4. I'm running 6.0.1 on Jasmine Rom 7 with all the rooted trimmings and no serious issues to date.

Screen resolution change ?

I see that samsungs and v30 got the option to change screen resolution to save battery. Is that option in the G6? (I currently got an LG G2 and want to upgrade)

No all we got is the option to change the acpect ratios for the apps

That's exactly why Im asking. Its a shame if you cant tune down the resolution and loose performance. Perhaps a custom rom may steal that function from the v30 now that is released.
My LG G2 never get hot. I wonder why new cellphones got this problem.

Yeh my phone geta hot after 15 min and loose fps....almost to unplayable state.... I need underclock cpu or lower resolution.... To keep it little more cool

Just tried the otpion from battery settings...game battery saver..custom. And for the game i play (mobile legends) i lovered resolution to minimum and i lovered the fps as well.. Its much much better.... But will test it more... It says resolution lovered .... So i asume it must be doing something... As i am sure we cant notice 2k and 1080p drop on such a small screen....but cpu should stay cooler... Test it as well and let me know how you get on...please
Note i launch the game from the menu itself...by choosing option play....

I think that only works with 3d applications but not affect daily use in wich the cpu/gpu need to move full screen resolution.

I still dont own the phone so cant test it but see a few videos/reviews about it and it render games at lower resolution. But only that, games, so all other drawing functions from normal aplications are not afected. It works as intended and indeed it help a lot in fast demanding games (like racing, shooters ,etc)

Yes like you said...did today hevay gaming over 1 hour.... No heat like before....warm yes...but no even close to it.... The resolution is noticeably lower..but i went to max fps and min res....
Defo a good feature...better then lower all res....
Cheers

I havent had any heating issues with g6. But resolution change would a thing nice to see with oreo update.

I bet we gonna get this in oreo update

https://goo.gl/UKaif3 This will help for the resolution but you have to be rooted

Oreo should bring resolution change option.

Non-rooted option: search Google for adb shell wm size and adb shell wm density commands. I haven't tried the size command but density gave me little bit nicer look and feel.

Bit of an old thread, but right now I'm running this res for better game performance:
adb shell
wm size 1080x2160
wm density 480
Notice that this causes the viewfinder in the stock camera app to be zoomed in and you won't be able to see the full image being captured. But I use the ported Google Camera which doesn't suffer from the problem.

Does it even run smoothly on pixels? It never ran smoothly on any of my phones, especially when zooming out during navigation, pathetic.

Has anyone successfully used this yet? I'm more interested in tying it to the power mode like high performance or optimized. Is that possible?

That being said I installed kodi and it seems like 120hz.
Easy to tell 120 from 60.
I don't think worth running video playback apps in 120 as video won't run in 120 anyway.

I don't understand how to import this into Tasker. When I click on the link from my phone, it doesn't give me the option to open it with Tasker. Is there any way you can post the actual file here?

When you click link in thread, click import and then click yes, this should open in tasker. Then you click on choose apps and pick which apps to run in 120 and rest go to 60.

I don't think this is working at all for me. There's a noticeable difference when I enable/disable the setting manually regardless of whether the Tasker profile is applying (which it says it is).

Someone said it does and they're wrong. It seems to run at about 15-30fps, just verified on my Pixel 4XL.
Places where this is evident are any in-app animations, for example if you tap on your blue location dot, it will animate to fill the screen with blue. Or if you search a location and tap its card, it will animate to pull the card up. Or you can just fling the map around. There's no way anybody with decent vision can confuse this with 60fps let along 120fps.

Hi Kev,
first of all thank you for the thread's and tasker profile regarding the 120Hz tingz!
The 120Hz experience on the S20 line imho is ULTRA disappointing!
Not the Display itself but more the way stupid Sammy implemented it Software wise.
First disappointment, the limitation of only FHD+
but this was known even before the S20 line was officially announced so I actively decided to look pass that. Even though most people say FHD+ is enough and you don't see any pixels or whatever, I have to say coming from a S10 with a smaller display and and higher dpi, I do notice how much softer the image quality on the S20+ is! It's noticeably less sharp.
The Second disappointment no one warned me about is the fact that half of the apps revert back to 60Hz!!!
No one told me this! and I ****ing hate this. Maybe I was naive, maybe it's the fact that I had no experience with a phone that has a high refresh rate display, but to my understanding if I set my phones display to 120Hz, everything, the UI and all apps would be displayed @*120Hz! But no! this already is like on the leaked Firmware Screenshot wich shows the "Dynamic" option in the middle! it's not locked.
Just shows again how important root is. The ability to take control of the device you own and not giving control to stupid Sammy dev's...
Your method with tasker works fine, but I had no experience with tasker prior and I only using it during it's trial period. After the trial ends, I'm not going to buy the full version.
Is there maybe a adb command that can globally set the phone to a fixed 120Hz refresh rate? Since I don't need a per app selection.
again thank you for this tasker profile so far.

Thanks for the profile! But there is one issue: it's works only once for my S20, then after launching few apps refresh rate drops to 60Hz ((( Even rebooting my phone doesn't help (

They have been, but on a different device and have worked well,
I have been looking back and forth to aosp how they are managing the refresh rates. to force x fps they use min_refresh_rate & peak_refresh_rate. What i have done here is that i made a custom task when you open an app to set this variables to these values for example peak_refresh_rate value = 120.0, variable min_refresh_rate value = 120.0. Then when you exit the app to set this variables to these values for example peak_refresh_rate value = 60.0 variable min_refresh_rate value = 120.0. These are system variables so you have to make sure that you select system and dont just leave at global

So let's say I have it set to open x app at 75 it will do it, but it won't reset it back down to 60 so it would just be stuck.

There is an App available now that someone created: https://labs.xda-developers.com/store/app/sszb.s20.refresh

This mod works fine, but why SAMSUNG don´t add this option in the menu?? Cause screen damage??? I don´t know... I revert to 120 hz.

Installed and trying... Works perfect at the moment, will see if cause less battery drain...

I did the adb commands early this morning before work and battery life has taken a small hit, but the extra smoothness is absolutely worth it. I considered installing the app, but I probably won't go back to 60 Hz, and 120 Hz is overkill. I think 96 Hz is the sweet spot

I used this adb command:
adb shell settings put system peak_refresh_rate 96.0 && adb shell settings put system min_refresh_rate 96.0
Phone web browser confirms 96-97 HZ on testufo.com
Battery drain is still just over 1%/hour, so 96 Hz hasn't significantly impacted battery, but makes a *huge* improvement in scrolling smoothness and overall experience. Putting my S20+ next to my wife's Z Flip, you can definitely see the difference when scrolling the browser and Twitter. I won't be going back to 60 Hz, so I don't need the app. But I appreciate the work that went into the app, for those who want to use it.

I use tasker with selective 120hz over all time 96hz. All video streaming apps I use 60hz and rest set to 120hz. I tried all time 96hz but battery is better my way bc if I watch a lot of video, it won't run higher than 60hz so 96 or 120 is a waste. Using tasker profile for selective 120/60hz giving better /same battery as all time 96hz. And 120 is noticeably smoother than 96 at least to me.

The app caused some problem in my S20+ Snapdragon. I installed and set to 96 when I'm normally set to 120, and 6 hours later my phone had dropped 47% percent battery. Nothing else unusual running in background or foreground. No idea why and I haven't seen anyone else report it, so maybe a fluke. Just thought I'd mention it.
