CM12.1 support DPI adjustment natively (if you see some apps still show bigger font, then try modify the build.prop to same value, this may help.)
========================
B320/B322 update screwed up below DPI adjustment. Thanks @medwatt testing, see #45 for details. For values like 240 or 260, the phone is completely blank, and if you do 'adb shell logcat *:E', you can see the resource not found error all over the place.
========================
Edit on July 3, 2015:
On Lollipop B309, the ro.sf.lcd_density is in build.prop already and set to 320, we can change it to smaller value: (make a backup first)
Code:
ro.sf.lcd_density=240
you can use any number between 240 to 320. Save then reboot. (Thanks @ArkAngel06 point out this entry still works)
Then everything is working fine. No expose needed and didn't see any big problem so far.
One problem we noticed is stock 'Browser' app FC, pls use your favorate 3rd party browser instead. (The one i currently use is boat browser)
========================
Following is original post for JellyBean 4.3
===Normal disclaims applies, be careful and know how to use adb to restore /system/build.prop before you try this=============
You phone may brick if this file got corrupted.
ROOT is required to change the LCD density.
Today trying to play around the DPI of display, and noticed the stock value is 320:
Code:
getprop | grep dens
[ro.sf.lcd_density]: [320]
But our 720p display native DPI is 240. That's why all the stuff display so big??
Anyway, I backed up /system/build.prop, and play a little bit.
I recommend simply use Root Browser with "RB Text Editor" to do the task. Other DPI changer app may work and convenient, but it is more risky and may do some change unknown to the phone. Due to lack of backup/restore recovery right now, I prefer manually editing the file myself.
Adding following to the end of /system/build.prop.
Code:
ro.sf.lcd_density=264
For some different varies like Consumer Cellular version, or MT2L05 version, you can try following if above doesn't work:
qemu.sf.lcd_density=264
Not sure it is a bug or what, when I use ES file explorer to edit the file, If I select edit mode right after open the file, it won't scroll to the end of file. I have to scroll to the end first in view mode, then select edit mode. Anyway, Root Browser editor works without any problem.
Following is some test result:
Code:
______________ System UI________ Settings__________ Gallery
180__________force close
200______________ok____________ force close______ force close
220______________ok____________ force close______ force close
240(native)______ok____________ force close______ force close
260______________ok____________ force close______ force close
264______________ok________________ ok____________force close
280______________ok________________ ok____________force close
320(stock)______ ok________________ ok________________ ok
Also, for all DPI less than 320, the stock lock screen shortcut is not displayed properly.
I think I will stick with 280 (update, now I am using 264) for a few days and see if I found more problems. And it should be easy to find an alternative gallery app.
The smaller font and everything actually make the display more clear and sharp
PS. I know there is font size in display settings, but the DPI change will make system zoom everything based on this new display density.
Thanks aragon257 and others feedback, some info from below is collected from the replies. Thanks.
MORE INFO/UPDATE:
. There is Exposed framework modules (like app settings) to do per app DPI settings. Please see end of this post for more info.
. The app force closing caused by lower DPI is purely software (view layout arrangement) issue, so lowering DPI will not do any harm to hardware.
. List of Apps that Force Close. I list them from higher DPI to lower DPI, The apps that crashes in higher DPI will also crash in lower DPI.
DPI 264 or 280: Currently I am using 264.
Lock Screen: No crash here. The app short cut moved to center of the circle, and requires less distance swipe to unlock.
Gallery (Also affecting camera since it start Gallery when you view pictures)
Alternative: "Galleray KK" and "Camera KK" from play store works pretty good, though it is Ads supported.
DPI 240:
Settings
Phone app when receiving calls.
Use Xposed Framework
OK, set DPI to 240 in build.prop, I need use Xposed module "App Settings" to set following App DPI to higher value to make the phone fully work:
Code:
Gallery(com.android.gallery3d): 297 (dp: 320x480)
Phone(com.android.phone): 264
Settings(com.android.settings): 264
SystemUI(com.android.systemui): 264
This number is set to lowest possible value, of course you can set to 320, then related apps will be bigger.
Please see attachment for some screenshot: (Left is stock 320 DPI, right is 264 DPI)
Thanks for doing all the research here
Use xposed and install app settings. Use it to give those apps that crash the default DPI. Just tried working great. And thanks about the tip of adb build.prop backing up.
Running at 240 DPI here.
Edit: Play store wouldn't download anything until I cleared the cache.
Edit again: Actually viewing images and trying to use the camera causes the gallery to crash... Ill fix it
FINAL Edit: Installed the kitkat camera and gallery. I had to unisntall the old gallery first. This works for me
Great, that xposed module is pretty cool, but for now I must resist as we don't have recovery yet
BTW, I have updated first post to correct the System UI FC number, it is 180, not 220. ie, DPI can be as low as 200 and the phone is still usable. So, native 240 is a pretty safe value.
Also, the "Huawei home" FC start showing up from 220 and below, though I am using Nova launcher.
Cheers.
I was having problems with incoming calls crashing the phone app. So back to 320, but using App Settings to change my downloaded apps to 240
Admired by this thread:
http://forum.xda-developers.com/galaxy-nexus/general/info-official-galaxy-nexus-lcd-density-t1392089
Call me bored, today I have tried more DPIs, and found 264 is the lowest number that Settings is working. Since the crashing is just cause by GUI view arrangement issue, nothing to do with hardware etc. So I will stick with 264 for now.
For the past few days with settings 280, I only noticed gallery is the problem. I didn't try too much widget/apps. Everything else I tried works pretty good.
Please refresh my memory, is lowering the DPI making the image smaller? If so, im interested.
yes, everything (font,icon,layout)will be smaller. but image actually maybe different story. try and see yourself!
so what apps are better in tablet mode for me to try?

I didn't use any particular tablet mode etc stuff, the lower DPI gives me more space asset, thats all.

ok, so Chrome, gmail, what would be good DPI for those? I'm a little worried about f'n up my phone and don't just want to do trial and error.
Is 240 the standard you all are using?

264 or 280 should be safer. 240 the settings app wont work.

ok, now with a twrp backup taken, I installed xposed and now i got exact same problem. 240 is really sweet dpi, even the lock screen layout is good.
I tried complete delete phone.apk, and contacts.apk, but looks like not easy to find a good replacement. other dialer app from play store still requires these two apks. And i checked my other phone 4.3 rom, they force close. will continue to the search.
Have you tried it with the xposed programs? I know it worked for gallery but not sure for settings.

Thanks. Didn't try gallery with app settings module yet. For 240 dpi, call out/in problem is what I am focused on right now.
Was trying app settings with 240, I set phone dialer etc. at stock setting but forgot had face lock so when I restarted, crash due to camera (what a [email protected]!) Thank you guys for TWRP so I could restore! . On vacation and no PC to try and adb to modify build.prop.

yes, with exposed module, at 240 dpi, gallery/camera works fine, settings also worked, only phone app still FC. so now i am at 264, and use exposed to fix gallery.
Silly question, app settings didn't work on dialer?

when calls come in, phone apps FC when dpi is 240 ( and app settings use 320 for com.android.phone)
EDIT:
OK, Maybe this defeat the purpose, set SystemUI to 264 resolve the incoming call problem. The incoming call crashed the phone app because the StatusBar trying to get a phone icon resource but failed.
To summary, In build.prop DPI set to 240, I need use Xposed "App Settings" to set following App DPI to higher value to make the phone fully work:
Code:
Gallery(com.android.gallery3d): 297
Phone(com.android.phone): 264
Settings(com.android.settings): 264
SystemUI(com.android.systemui): 264
This number is set to lowest possible value, of course you can set to 320, then related apps will be bigger.
>Change Screen Resolution<
Introduction:
I'm going to write this guide to teach you how to change the Screen Resolution of your Xiaomi Mi3/Mi4 AOSP/CM Based ROM to improve the graphics performance of your Mi3 without stressing your CPU/GPU while playing games.
What you need to Download:
Resolution Changer by NoMone:
https://play.google.com/store/apps/...apk&pcampaignid=APPU_1_TXl1VcrLFoWB8QXozIGIBA
Root Browser:
https://play.google.com/store/apps/...ser&pcampaignid=APPU_1_oXl1VczIG4_s8AX7-YLQCQ
Note: Default Screen Resolution of Xiaomi Mi 3 is 1080x1920FHD @480 DPI, well what we are going to do is Change it into 720x1280HD @320 to improve performance. (Don't worry about getting the icons bigger, the reason why we have to reduce the DPI on the Build.prop is to avoid glitches and make the Icons and UI at the normal size when changing the resolution, because using the Resolution Changer alone will cause some glitches on other apps )
Steps:
1. Open Root Browser; and find /system/build.prop and open it using RB Text Editor.
2. Find ro.sf.lcd_density=480 and change it to 320.
3. Click Save.
4. Open Resolution Changer; Enter 720 Width, 1280 Height, 320 DPI
5. Click Apply and wait for it to change.
6. Click Yes to Confirm and Skip on the next dialog.
7. Now exit the app and Reboot.
After rebooting, you'll see that you've changed the Screen Resolution to FHD>HD. :good:
Congratulation, to prove it do an Antutu Benchmark test and you'll see the difference. :good:
Additional Info:
(OPTIONAL IF YOU'RE USING CUSTOM DPI ON FULL HD)
If you were using a custom DPI on FULL HD for example;
You're using 400 or 380 or 370 on 1080x1920FHD Resolution,
Do these to properly change resolution to avoid getting the UI or Icons Bigger than Normal.
Example;
If you are using 400DPI on 1080x1920FHD.
400÷3=133DPI
400-133=267DPI
so the right DPI that you're going to use would be; 267DPI on 720x1280HD PLEASE, DONT FORGET to CLICK THANKS!
Everything is working almost perfectly. Some icons are larger than they used to be. But that wasn't problem. Real problem is that SwiftKey keyboard didn't scale. So I had to revert back to Google original keyboard to reset resolution back to 1080p

Oh I forgot to write something about Swift Keyboard, Sorry since I used Google Keyboard. but aside from Swiftkey everything is fine :good:
I have done this years ago. Not only CM/AOSP but all rooted phones.
Thanks for putting some guide though. :good::fingers-crossed:

I wrote this guide for those who are confused and experiencing glitches when using the Resolution Changer alone and of course for the beginners
added additional info.
I just noticed. I used 294 DPI for 720x1280

Alright! ?
Initially tried this with MIUI v5, turned out to be very bad. The icons became very large and going to back to native resolution didn't help either. Fortunately I had nandroid backup.
Later I tried it on MIUI 6, it worked!
Some glitches are there:
- On recent apps screen
- camera effects selection screen
- Calender and clock icons turned invisible
- Minor glitches in clock app
Otherwise everything looks good, and performance bump is noticeable. Excited to find out how much it improves battery life.
Thanks for sharing.

No problem
that's why it's for CM/AOSP Based ROM but I'm glad that it worked for you though there are some glitches.
Hi im using a a33 tab with screen dpi 160 and 480x800 resolution. Can I change this to higher resolution and dpi?

You can but, I won't recommend it because it would just stress out the processor and gpu of that low-end tablet, just leave that be.
Better use gl tools
While everyone gets larger icons,i am getting small icons,small screen,and all the app including resolution changer itself says the current settings is 1080x1920 with 320dpi.
Where am i doing it wrong?
I am on cm12 latest nightly.
same problem as Jongla here, running the same CM 12 nightlies. I guess the problem is that resolution changer doesnt change anything after you apply, current settings are kept as FHD res. Maybe try a different app to do it.

Try this method.Its easier and works just fine.
http://nexus5.wonderhowto.com/how-t...xus-6-by-lowering-display-resolution-0159881/
thanks buddy, this one works like a charm
cool trick..
It's become blurry, not clear like before
Guys, if you're using a CM rom, just install Xposed and install the App Setting module. Then, you just choose the app, turn on the custom settings, choose the resolution and dpi you want, and the app will run with those defenitions without having to mess with the entire UI on the device...
Now that we have root and kernel adiutor, we might be able to change the dpi to the screen dpi with it.
Has already someone changed this?
According to the dpi calculator:
https://www.sven.de/dpi/
We should have ~197 dpi, but there is 280 in the build.prop
Actually how many dpi does our watch have?
I set the calculator above to 2.3 so the result reads 1,63x1,63 display.
But other calculators are different...
Change it for whole android is not perfect. Try instead the Xposed module app settings to change dpi for specific apps.
Anyone using custom DPI on stock? What value are you using?
Edit the build.prop and add the line" ro.sf.lcd_density = 480 "and only change the value for whatever resolution you want. You have to be root and have a txt editor.
I recommend the file Explorer fx
ro.sf.lcd_density=480 <------stock, DPI Oxygen os
