LCD Density Changer is not giving me the options to set it as default density. I'm guessing it has something to do with Busybox as I cannot update my Busybox. Anyone else having this issue or know how I can fix it?
EDIT: Fixed it please using Titanium backup
i noticed that i was having issues on my tab as well, so i decided to delete the app even though i have the latest Busybox.
use root explorer to open /system/build.prop
find lcd densitry and change it to whatever you like
remount, reboot and enjoy
I just hit the problems button in titanium and it fixed whatever was wrong cuz it gave me the density setting back
Guys I heard by changing the DPI of Oxygen OS reduces lag..
It even improves the laggy camera app..
Never heard before..
If yes best way to change DPI & how much wil be better?
Root, then install le dpi changer.
It's just "ro.sf.lcd_density" property in build.prop file.
No need to install all kind of special apps. Just edit the file (root needed for editing system file) and reboot.
I found ro.sf.lcd_density=400 to be good enough zoom out,
so more stuff can fit on screen but still things are readable.
Use adb command from your PC: " adb shell wm density XXX" where xxx is your desired dpi. This can be done on rooted or non rooted devices.
I currently use 240 dpi but you can try different ones to find the right one that suits you.

First of all you need root and init d support.
Second i will not take responsibility if something happens to you're phone.
I tried screen shift for a long time, but it kept disabling the set at boot and i got sick of it. Now im using 1600x900 with 360dpi with init d script and could not be happier that it works perfectly.
1. Download the file.
2. Open your preferred file manager with root priviliges.
3. Browse to your download folder and search the file.
4. Remove the txt extension from the file by renaming it.
4. Open the file with text editor and change the resolution and dpi to what you want.
5. Copy or cut the file into /etc/init.d
6. Reboot your phone and boom! You have you're desired resolution and dpi set at boot.
Stock 1900x1080 480dpi file attached.
You can change the values with text editor if you wan't different resolution and dpi.
1600x900 360dpi setting file also included.
Eh?
Code:
adb shell wm density “INSERT_DPI” && adb reboot

What about the resolution?
I think that that only changes dpi.
I want more performance with lower res.

Code:
wm size "resolution"
wm size reset
wm density "DPI"
wm density reset
Does that also work with every boot?
I thought earlier that it just changed the value and after boot it would not stick.
Maybe i should not make guides since im a bit nooby with this. I just thought that it would make life easier for people like me.
I will just add the adb commands to it and call it a day.
Hey guys was just wondering if anyone can post a video with a changed DPI? I'm not routes and I heard it can be done without root but wanted to see what it looks like first would really appreciate it

Not sure where you heard it can be done without root. Because it simply can't. Without root you cannot modify system files.

It can be done without root but needs to be done using ADB on a PC.
On your PC while the phone is connected:
ADB shell
WM density 480 (or whatever you want for your device)
Restart your device to complete.
Just try it. U can easily go back to default. But i promise, u dont want :b
I am rooted on my Nexus 6P, although I cannot get it to change the dpi settings.
I tried using texdroider_dpi, tried the adb method and even went to /system/build.prop and changed it via ES File Explorer.
When I set the DPI to anything but 560 my SwiftKey Keyboard breaks but the overall screen density doesn't change.
The value I entered is still displayed in the build.prop though ..
I had it changed already, but when I updated to the latest security patch 2016 I had to reinstall my phone since I flamingod something I guess.
Went ahead with Heisenbergs guide and followed Step 11 (http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928) to get my phone back to work. Only thing not working now is the dpi change ..
Any help?
Are you mounting system as R/W and saving the build.prop after you change the value?

I didn't specifially mount the system as R/W - but when I restart the device afterwards the change is still persistent.
Try using another File Explorer (Fx with the root add-on for example) and make the change with that one mounting as R/W before doing anything else.

I do this but my Swiftkey is broken and some image elements are huge.
Does anyone know why something like texdroider used to work perfectly scaling everything and now it does not?
Before this update, after flashing the SuperSU 2.66 my twrp would give me the warning my phone was not rooted. Now, I do not receive this warning.

I have rooted my BTV-W09 model. When I use 'adb shell wm density 320' from my computer terminal, the dpi setting is adjusted correctly, but it doesn't survive a reboot.
I tried to change the dpi setting with a build.prop editor directly on the tablet and with the Textdroider DPI app, but it doesn't work, it goes back to whatever DPI settings was implied by the display settings (from Small-400dpi to Large-480dpi).
Is there a way to permanently change the DPI setting to 320, or at least a way to do it directly from the tablet (without a computer)?
Why you not reading neighbor topics? Install Xposed, install App Settings module from here for example, activate it and setup whatever DPI you wish.
Thanks Slavon, but I'm speaking of a system-wide change, not just app by app. English is not my first language, sorry if it wasn't clear.
Sorry if I was a bit rude. Try "Pimp my rom" utility. Find it on Google Play. I worked for me and now I'm thinking of how to revert
Edit: if I got it right, this utility adds (modifies?) this key in build.prop: ro.sf.lcd_density
Not at all, I understand how it seemed like I was asking a duplicate question without looking in others threads, sorry again
And thanks a lot for the advice, I'll try Pimp my rom right away !

If you just need to change density, you'd better try changing the value in build.prop first. And in case of any problems after, change the value of the key I wrote previously or restore the original build.prop from backup. Good luck.

I've tried this morning to change ro.sf.lcd_density to 320 in the build.prop and reboot. After reboot, ro.sf.lcd_density is still set to 320 but the display is still at 400dpi.
It's like ro.sf.lcd_density has no impact on the display dpi except for the display mode (tablet, phone, etc.).
Screen settings/Small + ro.sf.lcd_density=320 -> tablet mode in Chrome and 400dpi
Screen settings/Small + ro.sf.lcd_density=400 -> phone mode in Chrome and 400dpi
Screen settings/Large + ro.sf.lcd_density=320 -> tablet mode in Chrome and 480dpi
Screen settings/Large + ro.sf.lcd_density=400 -> phone mode in Chrome and 480dpi
I think maybe the DPI setting from build.prop is replaced during boot with the screen setting (Small:400dpi, Medium:440dpi, Large:480dpi). Could a init.d script could change the value after boot? I'll try tonight if the tablet allows init.d scripts to run.
Well, ok. I only quickly looked through the decompiled code. Change dpi with the app then, it'll make a backup of build. prop and try to compare both files - new and backup. I could have missed something. Just to mention, I didn't like the way tablet had behaved after changing DPI. EMUI is not well-designed for this. It's much better to set DPI for apps and leave it unmodified for system.
@wlausrsker this is covered in the apps running in phone mode thread. I posted there that the adb dpi change settings will stick after rebooting if you run the command "adb shell wm density 340 && adb reboot"*
*Use whatever density works best for you, I have found that 330 works best for me with the view mode and font set to large.

johje, thanks but I tried it first and it doesn't survive reboot ("./adb shell wm density 320 && ./adb reboot" since I'm on Mac, it reboots in 400dpi).
Slavon, I've compared the files from before and after changing the dpi setting with the app, only ro.sf.lcd_density is changed, so you didn't miss anything.
Since methods successfully used by you and others don't work for me, it must be something I did differently on setting up my tablet. I used greatslon mod of TWRP and then flashed via TWRP the latest SuperSU (v2.79-SR1). Finally, I installed XposedInstaller and got xposed-v87-sdk23-arm64. Did any of you with reboot-surviving custom dpi setting used something different? (like the SRK Tool)
I'm off this weekend but I'll try next week to start over from scratch.
the reason adb change dpi and even build.prop change doesn't work is because huawei has set lcd_density in boot image. check content of /init.6x.rc
these init files are part of boot.img and will be overwritten at every boot. so what u need is a modified boot.img where this set lcd_density line is removed. Once you install that boot, you can set whatever dpi in build.prop and it will work. even adb dpi change will be persistent.
if you are on b026, i can share my edited boot.img
Thanks for the explanation bark1234, I now understand why everything I tried didn't survive reboot!
Thanks also for proposing your edited B026 boot.img but I'm on BTV-W09C100B005 and I can't find any B026 download for BTV-W09. From what I understand from other threads the latest Chinese OTA for the BTV-W09 is the BTV-W09C233B022, so I couldn't use it. Nevertheless, if you could maybe share it for others, it could help someone with the same problem on a BTV-DL09.
I tried to edit my boot.img but I'm a newbie. I've tried to extract my boot.img but I have no result with "cat /proc/mtd", so I extracted mmcblk0boot0 as a best guess. I tried to install abootimg to edit it but there's not blkid.h on Mac OS so I can't build it. If I give you what I extracted, could you maybe edit it like you did with yours? You would save me from applying at random a bunch of tutorials like I just did and hoping it will result in something usable In the meantime, I'll try and learn how to edit a boot.ini with my setup.

Just as an FYI, the adb dpi change initiated along with the reboot command has stuck for me after multiple reboots.

If you are rooted, use flashfire app to get ur current boot.img from ur phone. and then copy it out to edit.
The tool i use for editing works on windows. i too have mac only, i have windows on vm in it.
https://www.dropbox.com/s/x46q5nzv49iauwi/Android Image Kitchen.rar?dl=1
Use above link to download tool i use.
unpackimg.bat will unpack boot img.
your init.x files will be in ramdisk, edit it there.
and then use repackimg.bat, it will create new boot.img.

johje, it won't stuck for me, no matter how I try. Did you root by flashing the latest SuperSU? Did you installed xposed framework?
bark1234, thank you very much for the detailled explanation, I'll use Flashfire app to extract my boot.img and I'll try tomorrow at work on my Windows machine to edit it.
@wlausrsker I have not yet rooted my tablet. Once I got the dpi/phone apps issue fixed, it reduced my urgency for rooting. However, I will be rooting it soon, since a way has been found to enable the 5Ghz wireless adapter for the US version of the tablet. I will let you know if I am able to keep the dpi settings after rooting.

Thanks again for the link and the explanation, it was really a painless process.
I used Flashfire app on my tablet to backup my boot.img (it resulted in a boot.lz4 file).
On my Windows machine, in a cmd window:
Code:
lz4 boot.lz4
unpackimg.bat boot
I then opened in Notepad++ the /ramdisk/init.61262.rc file to remove the line setprop ro.sf.lcd_density 560 in the on early-init and on boot sections of the file and saved.
In the cmd window:
Code:
repackimg.bat
rename image-new.img boot.img
I now have an edited boot.img to flash in TWRP. Does it seems to you that I did the editing correctly? The edited boot.img is 13.35Mb (about the same as the boot.lz4) but the extracted boot file before the unpacking was 32.77Mb. Is it normal?
13.9 is correct size. install this boot.img
For those of us following along. Does the edited boot image have to be flashed by TWRP in zip form? Or can we use Fastboot to flash it? or both will work?
I've done the edit's and have what I believe is a flashable zip. I personally like to use fastboot.
I have DPI set and holding by adb as I mentioned before but this is still nice to have.
Thanks
OP - here's a really easy way to change dpi and make it stick: https://play.google.com/store/apps/details?id=com.texdroider.texdroider_dpi
I'm using it on my MediaPad M3 without issues. PS - 320 is my preferred dpi as well, but I found it caused some issues like Settings would crash. I'm using 322 now without any issue for the last couple weeks. Enjoy
