For the sake of completeness (most of you will have noticed this app already): For a change, Samsung have done a fantastic job and released a great app called "Game Tuner". It's simple to use, doesn't even need root, and renders all of the stuff I wrote below obsolete!
What it does is, it renders each game at an individual screen resolution, frame rate, and texture quality (texture quality only working for me since MM upgrade).
All you have to do is install Game Tuner from Google Play (above link), start it, follow the instructions to install GameMode through Galaxy Apps, and you're good to go. Create a custom profile, set default values (e.g. 75% resolution=1080p), activate the profile. Set different resolutions for other games. And if you want to control apps other than games, tap top left menu, and chose "Apps".
I've done the same benchmarks as with the method below, and the results were exactly the same, so it's really working, but without messing up the UI or impairing system apps like the camera.
Hey folks,
I've decided to put together a little wrap-up of the stuff I found regarding the sometimes rather poor 3D performance of the Note 4. This is only for experienced users who are familiar with things as rooting, backups, adb, in general: unbricking their phone if bad things happen. As usual, I don't take any responsibilty if you brick your phone or destroy it in any other way. Just make sure to activate USB debugging, and if anything goes wrong, either follow this guide, or simply reflash your ROM.
Just make sure you make a Nandroid or at least Titanium backup before you try this. Better safe than sorry...
It comes as no surprise that running a cpu at almost 3GHz takes its toll. Demanding games such as Real Racing 3 or XCOM:EW, or emulators such as PPSSPP cause the cpu to heat up rapidly, until it reaches ~80°C, before it gets mercilessly downclocked to cool down. At this point, you start noticing more or less pronounced performance drops. There isn't really much you can do, except using a custom kernel to downclock cpu & gpu, before your phone does.
But apart from that, there is another, even greater performance hog, which is also one of the main reasons for the overheating issue: the QHD resolution of our Note 4's screen. We're talking about a 3.69 megapixel resolution, that's almost twice as much as Full HD (2.07 MP), and exactly four times as much as HD (0.92 MP). Gorgeous and brilliant, beautiful to look at during everyday use, but pushing the Adreno gpu to its limits when it comes to gaming.
So, an ingenious guy called NOMone has created a nifty little tool called "NOMone Resolution Changer", already some time ago. It's available for free at Google Play. It's been widely discussed here on xda and on other forums, but I want to share my experience specifically on the Note 4.
Btw, it seems he only posted here two times, so he's most likely not active anymore, but you should head over and thank him anyway.
Now, if you're thinking "no way, why should I deliberately sacrifice my QHD resolution?", read on nonetheless. Because this tool is extremely easy to use, and if you only switch the resolution before playing a game, and revert afterwards (it's only one click), you won't have to sacrifice any visual quality. The settings stick after a reboot, so make sure to really restore defaults if you want to go back to QHD.
The trick is to use the appropriate resolution and dpi values, so your screen doesn't get mixed up.
The results are impressive, sometimes even staggering. Has anyone ever wondered why PPSSPP doesn't perform better on a Note 4 than it does on a Note 2? Here's the reason. PPSSPP gains so much performance , it's almost unbelievable.
I've also done some benchmark runs to measure the improvements (yeah, I know, benchmarks are bad, but still :angel: ). The improvement is clearly visible and, even more important, reproducable:
GFXBench GL Benchmark 3.1 (Manhattan):
1. 1440p: 449,4 frames, 7.2 fps
2. 1080p: 800,6 frames, 13 fps (+78%)
3. 720p: 1621 frames, 26 fps (+261%)
4. 480p: 2728 frames, 44 fps (+507%)
This is plain awesome. The Note 4 is listed even lower, with 434 frames, in the device list, while the 1080p Galaxy S5 reaches 775 frames.
AnTuTu (gpu score only):
1. 1440p: 16210
2. 1080p: 21253 (+31%)
3. 720p: 22524 (+40%)
4. 480p: 22523 (+40%)
Obviously, by comparing scores 3 and 4, the Note 4 hits the fps limit at HD resolution, so there's no more room for improvement in AnTuTu.
Seascape Benchmark (detail setting: Very High):
1440p: 26.9 fps
1080p: 46.6 fps (+73%)
720p: 53.4 fps (+99%, sometimes hits the frame limit of 59.0 fps)
480p: 59.0 fps (+119%, hits the frame limit constantly).
This is a beautiful OpenGL ES 2.0 test, so no cpu scores interfering with the result. Again the fps limit prevents a higher score, but nonetheless, this is pretty amazing.
Other benefits: if you're using a custom kernel, you can run gpu-intensive games at lower cpu speeds to keep the cpu temperature in check. In my case, XCOM:EW runs smoothly @ 30% (!!) cpu speed. This way, the cpu doesn't heat up to more than 60°C, which means it doesn't get downclocked while playing. If you like, you can also automate the process of setting the cpu speed with the aptly named app "Automate" . Which is fantastic, btw.
Now what about visual quality?
Seriously: it's hard to tell the difference. If you look very closely, you can see the display isn't as sharp in FHD as in QHD. But if you look that closely, you're in constant danger of triggering some random app with the tip of your nose. At normal viewing distance, especially while gaming, it's impossible to tell the difference.
So, are there any drawbacks?
Yes, there are: the UI gets messed up a bit (e.g. bigger status bar, some Samsung apps don't fit on screen anymore), and NOMone Resolution Changer doesn't seem to work with CM12.1. Well, at least for me, and other users reported so as well. I tested it some time ago, while I was on CM12.1, and even thought it was a fake app, which it isn't! Seems that the resolution is somehow hard coded into CM12, and you can only switch dpi. There's probably nothing you can do when you're running CM, except try your luck.
But if you are running a Touchwiz ROM, stock or custom, it should work as intended (Emotion Revolution ROM r10.1 in my case). And you can simply ignore the UI issues, as long as you only switch the resolution for gaming. It's not a real issue then, because the status bar is hidden anyway while the game is running.
If you want to keep your device running at FullHD permanently, it's a bit more complicated: first, you'll need Xposed, so you can use the App Settings module to set Android System and SystemUI to 480 dpi. This'll fix the UI (Not needed. Just reboot)
Some apps like phone, contacts, S-Note scale down to the lower dpi setting, whereas Samsung keyboard and the camera won't (camera works, see post #10 below).
So you'll have to install another keyboard like SwiftKey (if you don't have it already), find a working camera app (3rd party or hacked Note 4 camera), and clear your Google Play data (at least I had to, it wouldn't install any apps after the changes), and you're good to go. There might also be other issues I'm not aware of yet. But apart from the ones I described, everything's working fine so far.
Have fun!
you don't need root to change the dpi and the resolution.
enable usb debugging and adb the following:
adb shell wm density 480
adb shell wm size 1080x1920
adb reboot
if you want to revert back:
adb shell wm size reset
adb shell wm density reset
adb reboot
the changes persist after reboot.
I am using it like that for some time. Everything is much faster. Even the browsing..
the only 2 bugs I noticed is the Samsung keyboard (i switched to swiftkey) and the action memo (c'mon Samsung devs, code properly..)

You're right, you don't necessarily need this tool. All it does is simplify the process. And you should really be able to use adb commands to fix your phone when you mess it up. But NOMone's tool comes in very handy when you're away from your pc and need to switch resolutions quickly. In my case, it's when I want to use the camera: the UI is messed up at 1080p and I haven't found a way to fix it yet, except switch back to QHD. Or the other way round: if you want to play a demanding game on the train at lower resolution, but go back to QHD again.
I'm using 1080p resolution permanently now, because I get a smoother UI, a cooler phone, better battery life, and much better performance. I hope they don't give us 5" UHD screens next...
Could you please explain what is wrong with the camera on 1080p 480dpi? I am using these settings and have 0 problems with the camera. Just curious.. If possible please attach a screen shot. Cheers
The UI is messed. I can't see most of the buttons, and can't take a photo, see attached screenshot.

very strange indeed. My device is n910f as well. Not rooted and fully stock. I used the Debloater app to disable all unused apps (works via adb) and the method descried in my other post to change the resolution and dpi. The camera is working absolutely fine i.e. no visual changes or glitches. As I am not rooted I am not sure if I can give you the camera apk. It is basically the same apk as in the stock 5.1.1 BTU rom. Try my method on the stock rom with my values and I am sure it will work.
Cool

Well, I went ahead and downloaded _alexndr's COI3 stock debloated rom base (Deodexed), extracted SamsungCamera3.apk, replaced the one in my /system/app dir, set permissions, rebooted, and everything's working fine now. :good:
No idea what the Emotroid guys did to the camera app.
I've attached the apk to this post in case anyone else is having this issue.
Man, I've been playing XCOM:EW at 720p, and my phone didn't get warmer than 59°C, even after 2+ hours. And the performance boost is just so incredible... Turns out I don't even mind the 720p resolution in 3D games, it didn't bother me at all.
Just a warning:
I just managed to render my phone useless with this. After changing resolution and DPI, the phone did a soft reboot (as it should), startet booting, then, after the initialisation of systemUI reboots. Has been Bootlooping the past hour. ADB doesn't work, as reboot it's unauthorised and boot loop doesn't allow for any authorisation. Tried resetting via build.prop and userinit.sh. Even Direct Script Injection into init.rc didn't work.
Cache wipe -> no chance
System wipe and reflash -> Nope
In the End i ended up factory resetting and reflashing complete rom. This did work. Not to rant or anything, just a little story for those that are not capable to troubleshoot problems: This might screw your Installation!

Hence the warning at the beginning of the thread.
But seriously: which method did you use? The NOMone app or the adb commands? Because only the adb command needs a reboot to take effect, NOMone does not reboot: it changes the resolution on the fly, then waits 10 seconds for confirmation and switches back to default resolution otherwise.
It's impossible to tell what went wrong in your case, might have been anything from a bad adb command to a malfunction of the app or your rom. I guess if you enter bad values, both methods might break your SystemUI. I managed to do so by using Automate to activate the shell commands on app launch (no bootloop, though, only permanent FC of SystemUI), but I was able to fix it with adb easily.
It's a shame it didn't work for you, most people who are using this method are very happy with it.

Yes, it does, at least a bit. The screen does still burn a lot of juice because it's so big and bright, but the cpu stays much cooler. Less heat=less power consumption.
Thanks alot , i'm on simplrom v5c and googy max kernel v2

It was completely my fault. I knew what i was getting into, so no problem. It's just that, the "mistakes" i did could easily be done by accident by some less experienced users.
First off, i'm on CM12. NOMones Sollution doesn't seem to work there. CM does a "Hot Reboot" to reload the system UI. No matter what you set in NOMones app, the resolution doesn't change. DPI does though. This seems to be a CM related issue. Maybe they hardcode the resolution at build time...
After that i tried another app, which had the Orientation labeled backwards. So it set 1920x1080 landscape instead of portrait. After that the Phone Bootlooped the System UI. It would always boot up to the PIN Enter Screen and then reboot.
As said, no big Problem. I knew what to do and was able to bring my phone back to working state. Just make sure that you are 100% sure about the numbers you put into such apps and keep in mind that even with such "small" changes you should always have a up to date Backup of everything.

It should, unless SimplROM is CM12-based. NOMone Resolution Changer, as well as similar apps and the adb method, aren't limited to specific devices. In theory, they may all work on all Android phones. You'll have to try it out yourself, just make a backup before you do so!

Right, thanks for clarification. I don't remember the hot reboot in CM12, but I know the resolution switch didn't work when I tried it on my Note 2 some time ago. Funny that for once Touchwiz is more customizable than CM.
If you're still interested, but hate the Samsung colour scheme (like me), you can try out Emotion Revolution ROM r10.1. It's based on the latest COI3 TW firmware, but they themed the notifcation/status bar and toggles to somewhat more like stock Android, see attached screenshot. Looks pretty sleek, performance is easily on par with CM12, and the Emotion kernel has tons of great tweaking options. Or you can go for their Port Note 5 r2.1 ROM, also based on COI3, which should offer full Theme Store support. That's the one I'll flash next. :good:

Here's a quick way to boost Z's performance so its on par with the Z1, including the graphics performance.
1. Change resolution to 720p - personaly i dont see any difference between 1080p and 720p, even if there is the huge performance boost is worth it.
A. -Go to build.prop and change density to 320
***Make sure you change DPI in the build prop and not with ADB or other apps***
***When using ADB the change is made while booting and leads to issues***
B. -Connect to pc with debugging on, in adb -> adb shell wm size 720x1280 ->reboot
It will look weird before the reboot, if still looks weird try "adb shell wm size 1280x720"
Use adb for the resolution and not terminal emulator, if anything goes wrong you can revert to stock with adb easily
2. Freeze apps
Thats what I froze, if youre using any of the apps obviously leave them out

Optional but recommended:
-Seeder with all options on and light profile
-Greenify donate - this way you have notifications from whatsapp etc without it running all the time
-Disable animations, use AOSP lock screen to get rid of black wallpaper bug -> browse to system\app find Xperialockscreen.apk and change to Xperialockscreen.apkk
-Nova launcher
-In apn settings dont use proxy for apn or mms -> this way you dont have ads if you use adblock

Zero lags and AOSP like performance in setting menu
Revert to stock
1. Go to build.prop and change density to 480
2. Connect to pc with debugging on, in adb -> adb shell wm size 1080x1920 ->reboot (it will look weird before the reboot, if still looks weird try
"adb shell wm size 1920x1080")
Use adb for the resolution and not terminal emulator, if anything goes wrong you can revert to stock with adb easily
I don't see any difference between 720p and 1080p too. More and more pixels on a screen is useless *cough*2K display*cough*
yeah especially from a distance when watching movies, progress is good and we have the option to reduce the resolution for better performance, so we really shouldnt complain.
But lets not turn this thread into resolution wars
I don't know about the adb shell thing, but changing density DOES NOT change screen resolution. It just changes the density of the elements rendered in the screen.

But when my phone rebooted,no anything changed.

apologize for my poor english.
Thank you very much
@quadraiser if you changed DPI it should look like nothing changed.
Check antutu benchmark device info see what it says about screen resolution
would this also positively affect battery life?
Change into HD may improve battery life ??
What happen if i change 480 -> 400 ??
@Incanity @sonconvn
720p is easier on the cpu\gpu so you get better battery life, I defiantly noticed an increase in battery life
@sontran_vietnam
Change to 400 and its going to be all big and ugly
You can change with "adb shell density *value*" to see what it looks like, but make sure you change it in the build.prop as well when you decide whats best for you.
Xperia home doesnt work well with anything but stock density 1080p->480, 720p->320
@Pandemic
Saw your post before you edited
All stock roms are basically the same, I like the extra options in settings menu (appops\auto starts) and theming he has done
You recommend Xposed, but it slows down the system, also you can simply rename the stock lockscreen.apk to get AOSP lockscreen.

Didnt know about the lockscreen, thanks.
I dont see much of a slow down with xposed, besides gravity box is awesome

May be, but its a fact that xposed as well as any theme engine will slow down the phone.

Hi guys,
i tried many things to change the display resolution(to hd instead of fullhd), google'd a'lot ... but whenever i try to change the screen res with CM13, the phone restarts or doesn't apply the res.
the reason why i like to change is because of some heavy 3D games run much smoother (more fps, the phone becomes not hot, lower battery usage) which is working very good in TW roms.
If someone knows a method, or atleast a "per app resoluion change"(don't care about system UI res) please share your knowledge, thanks in advance
things i tried already:
'resolution changer'
'NoMONE' resolution changer
'Screen Shift'
result all in a phone reboot or bootloop
Update:
Ok, it did work over adb wm size, testing some things
I thought it would be good to have this in one seperate thread. The PRIV has a great qHD display but I don't think qHD resolutions make any sense on mobile devices. Problems like framedrops, low framerates, heat and battery draining can be the result.
Luckily, although the PRIV is unrootable, the commands wm density and wm size still work when applied through adb shell with USB debugging turned on. (If you don't know how to do this, there are many tutorials out there).
The PRIV has a native resolution of 2560x1440 @ 560ppi. We will change this to 1920x1080 @ 420ppi. To do so enter the following two lines:
Code:
adb shell wm size 1080y1920
adb shell wm density 420
Then reboot your device manually or simply enter:
Code:
adb reboot
To reset everything to normal enter:
Code:
adb shell wm size reset
adb shell wm density reset
Then reboot.
Hope this is helpful to you. Now I really like my PRIV and get stellar battery life and SoT:
WORKING ! thank You for that
After applying and rebooting, only a third of the screen was filled by the UI in the center and was very small. The rest was blank, not even navigation displayed.
Tried on the Priv bought from Blackberry direct on the latest update.

Setting a higher density enlarges the fonts for better readability (which might be important for people in their 40ies ). I experienced setting values 450 or 480 is still OK. Higher values hide some things from the productivity bar.
Unfortunately, picture password is not working any more.
It seems that the display needs about 150 mAh per hour with the reduced resolution. Can someone check the initial energy consumtion to quantify the gain (if any).
Thanks
Here is a screenshot of the current energy consumption.
I will try out the commands later.
For comparison:
Time on: 2h 4m 25s
Computed power use: 436 mAh
With default resolution.
Anyone know how to correct the corrupt BBM icon in the HUB after the resolution/DPI change? The BBM icon turns huge on any density change and it looks incredibly ugly.
After having the reduced resolution active for one week, I'm switching back to default. It seems that for daily use there isn't much difference. I observed a couple of scaling issues (mainly with BB apps but also others) and decided it's not worth. I guess it will make one for sure when playing 3d games, but that's not my device usage.

The reason why BlackBerry apps get affected is because they don't follow proper Material design guidelines. Sadly I feel that this is something that will plague devices for a while to come. So far I too am not noticing much difference in performance or battery life.
is there a way to pin the image on the bottom right of the screen?
also, does it completely ignore touches outside of the image? ...or am I reading wrong and the image will be stretched over the entire screen?

The screen uses only almost half of the energy when it's in FullHD mode. That's a HUGE difference I can live with those little scaling issues here and there.
priv resolution, dpi
i change just the resolution, does it have a point, i do not wana change the dpi for the fact that is going to overscale a lot of thing, and for exemple i can not change my whatsapp photo if i change the dpi....
What about 720p-mode which is more natural to upscale on qHD than 1080p? Has anyone tried?

I tried but it's very ugly so I prefer 1080p

Interesting thread. I just bought a new phone because the priv battery is dying, and I couldn't find a new one. But I had to drop screen resolution to do that, since I didn't want a physically larger device. I miss the sharp resolution and greater "real estate" of the priv screen.

Using an A2017U B29 stock rooted. I find the phone to be generally laggy, especially in opening apps or switching apps, but even in things like SwiftKey appearing… My OnePlus One felt faster. And also (separate issue, I understand) double-tap to wake is slow, as is screen-on in general.
Please share your tips for speeding up the phone. If you can include links to tutorials or explanation threads where relevant, even better!
Thanks :good:
That's sorta unanswerable but my first cheap tip is to disable window and menu animations. I imagine some manufacturers tweak the timings so you don't feel the lag- I mean... animations are intentional lag, right?
Just go into developer settings near the bottom and turn them to whatever the next to lowest setting is. Personally I just disable the 3 animation settings because they're dumb. A window fade-in/out effect is telling your computer to do a math equation each time you switch a window. I'd rather the window simply open.
The same goes for 3d and transparency.. Unnecessary math. Even Microsoft got rid of the Windows Vista orb start button in Windows 7 because it shaves a few cpu cycles off to render a square versus a circle.
get fstrimm from the playstore
Thanks! I had turned off some of the animations already but turned off the other two now as well. Didn't see a big difference. Not sure how to turn off 3d and transparency (and wouldn't that affect how apps look?).
Moved my photos and videos to the SD card… that helped, too.

Thanks — I did. Not sure yet if it made a difference... Moved my photos and videos to the SD card… that also helped.
Upgrade to the ZTE Axon Dmix7 custom ROM. You can dirty flash it and continue using your software since it is just an optimized Stock ROM. It is by far more agile than the Stock B29. It is fully reversible, since you can also dirty flash the stock B29 ROM again.
On top of that you can increase your user experience by more than 10% by reformatting your data partition to F2FS. This process is also reversible and very easy following the guide you can find in my signature.
I am using AKT kernel tweaks for SD820 since 3 days. My phones feels blazing fast now, and batterylife improved too. Check it out!

(you need to be rooted and unlocked to use this)
When it comes to screen Sony definitely tops the list above other manufacturers but our Xperia Z5 Premium doesn't always use 4K HD Resolution Screen, only when watching 4k video or things right? so why not to make it work in always 4K mode? more pixels- more fun
Warning: Note that on high brightness battery usage will be much more than 1080p screen mode
it requires Rooted device also
1.Download Terminal Emulator from play store
2. open app and write "su" without quotes
3. give it root access and write " wm size 2160×3840 " also without quotes
Screen will became "ugly", to fix it now type "wm density 820" also without quotes. after that all should work fine, play any video and you'll notice color changes and much More improvements, however there's always a way back to 1080p
to do it
wm size 1080×1920
wm density 420

感谢楼主的分享，支持楼主！
Just thank you! It gave it a different and nice appearance but I noted two things. First the phone works a little slower and the other thing is when I tried to make a call the caller interface didn’t open so I was not able to make the normal functions like turning off the microphone, hanging up the call, etc. Unfortunately I had to put it back to 1080p.
you don't need root for this, you can do it with adb command though a pc without root
"adb shell wm size 2160×3840"
"adb shell wm density 820"
cheers

Hi Guys! I know you have lurking about that unutilized 4k screen of our phone, Why not enjoy "1440x2560" density of 534 works perfectly fine the only down side are glitchy looking start-up since it was designed to in 1080p and multi tasking has no thumbnails on it about it looks and feels good!
Just do
adb shell wm size 1440x2560
adb shell wm density 534 <-----------IMO this is the density, fonts looks smaller but legible.
ENJOY!
"You can do the same also on your Z1, Z2, Z3, Z4 Tablet, Z5, Z5 Compact ..... and on your crapold device, because this is not changing the display resolution
Seriously guys..... this is changing the resolution of the VIRTUAL display (not the physical one), so like this you are getting 4k emulation on 1080p physical resolution.
To change the physical display resolution you need to do "quite a few more steps", which cannot be done in a simple way like this (and surely not without root).
Moreover, even if -- yes, there is a way -- it's not doable on stock ROMs, as it misses the required implementation.
I am almost done here so, on Open Devices, you will be able to get real [email protected] whenever you want."

I wana buy Xperia Z5 Premium only for VR to watch 4K videos. Is still good? Can I play UHD 180° videos smooth, without any reboot with this mod?
hi does anyone have issues taking screenshots with these settings enabled? every screen shot says error app does not allow?
