[INFO][HOWTO] Official Galaxy Nexus LCD Density Modding Thread

***REQUIRES ROOT***
This thread will serve as a discussion for modifying the LCD Density of the Samsung Glaxy Nexus. Stock density is 320 dpi, and the preferred modded density is 240 dpi. Please feel free to discuss lcd density, and notify me of anything you want added to the list.
Why modify the lcd density of your phone? Simple answer: more screen real estate.
1. How to modify you lcd density
Note: You can always go back to 320 dpi at any time by following these same steps and putting 320 back in for 240!
240 dpi is the recommended modded dpi for the Galaxy Nexus. You can however set it to whatever you want. Just know that many dpi's will cause the on screen buttons to disappear, and even possibly cause the launcher to crash. In both cases you can use the adb method to restore to 240 or 320.
241 dpi is also a good number to try. It fixes the problems some apps have when running at 240 dpi. Credit goes to g33k3r. However it will cause market incompatibilities. Read #6 to fix this.
246 will fix the contact widget, and quick contact, but it will use the old style contact info which shows a large contact image above their info, not small and to the side. Credit goes to maddler.
250 dpi OR 260 dpi OR 280 dpi are also good values if you would like a smaller than stock value, but 240 is too small for you.
Method 1 (Using an app):
Download LCD Density Modder (Free) / LCD Density Modder Pro from market. Set density to 240 or 241, apply, then reboot. There are multiple different apps that can change your dpi, but this app is guaranteed to work on the Galaxy Nexus.
Method 2 (Modify a file):
Using Root File Explorer or a similar program, modify /system/build.prop file (must mount /system as r/w).
Replace:
ro.sf.lcd_density=320
With:
ro.sf.lcd_density=240
Save and reboot.
Method 3 (Using adb):
adb pull /system/build.prop C:/build.prop
In build.prop, replace:
ro.sf.lcd_density=320
With:
ro.sf.lcd_density=240
adb remount
adb push C:/build.prop /system/build.prop
Reboot phone.
2. Apps where UI is different on 240 dpi (for better or worse, ui elements have been rearranged, but none are broken)
Launcher: Home screen icons are still 4x4 and squished into the center of the screen. App drawer and Widget drawer do not fill. There is a mod that fixes this in this thread: FIX HERE
Market: Now has 2 columns instead of one when listing apps.
Gmail: Quick access icons have been romved from the bottom and placed on the top. Only first two icons are visible, other are collapsed into the drop down menu.
People: Contact info now has a two column layout: a small icon of contact on left (static) with all of the contact info as a scrolling pane on the right (no visible divider). Favorite contact icons are much smaller.
3. Apps where UI is broken, but still useable
Sports Tracker: Some interface items dont stretch to fill the screen.
ADW /ADW Ex Launcher: There is a blue line and a menu icon above the homescreen at all times.
Speedtest.net: App shows up centered on screen, not filling whole screen.
Kindle: It still works but the text is now centered in the middle and there is a large amount of paddling around it.
4. Apps where UI is completely broken
Music: App displays incorrectly at 240 dpi. Run at 241 to fix this
5. Android UI glitches
Sometimes when selecting text the menu bar on the top of the screen will have a weird blue streak across it.
Stock ICS keyboard the popup when you press a key seems like it gets clipped off a little on the bottom.
Clicking the picture of a contact either from the people app, or from a 1x1 contact widget you no longer get the quick access popup, instead it is now the person's contact picture blown up to full screen and half cut off on the right side.
6. Market apps incompatable with device (according to market)
None that I know of. Since 240 dpi is a standard dpi for most android phones, I don't envision very many apps being incompabile. If you find an app that the market say is incompatible, you can try setting your density back to 320 temporarily in order to download it.
For those with market issues on a non-standard dpi (241, 250, 260, 280 etc.), try this:
1. Boot your phone into 320 or 240 dpi mode (depending on which kind of compatibility you want).
2. Find the Market app under manage apps. Click uninstall updates, clear data, clear cache.
3. Find Market Updater under manage apps and click Disable.
4. Open Market and accept terms of service.
5. Change dpi back to 241 and reboot.
Alternatively, LCD Density Modder Pro has the ability to download and install a modded market apk to fix market compatibility issues.

can you provide a screenshot?
like a before/after pic.

I think this is crazy.
The stock DPI is amazing.
Get an SGSII if you want an old-school resolution or have bad eyes.
My stock DPI is absolutely beautiful...

You are completely missing the point. On Android when you change the DPI, you are essentially telling android the size at which to "scale" all objects on the screen. Notice how the Galaxy Nexus has a 720p screen yet you can only fit 4x4 icons on the desktop like the Galaxy S2? Well that is because the 320 dpi is telling android to scale those things bigger. Setting it to 240 dpi will make everything smaller and give you more screen "real estate". The resolution is still 720p.
You mention having bad eyes, but when you lower the dpi you actually need GOOD eyes because everything is smaller and harder to read if you have bad eyes.

YouTube crashes on launch for me when set to 240 DPI. I have not performed a wipe, though I have tried wiping the settings and cache for the app.

Ah yes, thanks for reminding me. YT crashes for me as well, however if you have the widget you can click one of the videos and it will open that video. You can search for videos from there, but you cant access the home page for some reason.
EDIT: It turns out if you open youtube in landscape mode it will work!

Well thx for the Tip with the density. But however...When I start DPI Changer I get an error "Unable to read configuration file"
Any ideas?

Do you have Root File Explorer? You can use the second method i listed to change the build.prop file. You can also use adb to pull the file locally, edit it, and push it back to the phone.

Oh ok then I will do it manually
I will report back soon ...I hope xD

Awesome. Make sure to check out my modified home screen launcher to get the full effect:

Also, if you find any apps that don't display properly or something else is wrong with them (when running in 240 dpi), please post back in this thread to help inform others.

Mhh I use adb launcher... but on top of the screen is now a blue horizontal line with the three dots for options on the right side....
Will your mod take care of this? I hope you know what I mean...

I have ADW Ex launcher and i see that as well. It is the default titlebar and menu system for apps in ICS. Did you experience this when in 320 dpi as well or only in 240? I haven't tested it in 320.
And no, my mod only affects the stock launcher so it will not fix your problem.

No with 320 dpi that line doesn't appear its there since I have 240 Dpi...
Tested your Launcher replacement...
Great Work
But as you said it will not fix this "line affect" in adw
Maybe in a future update in adw launcher it will be fixed.

I added photos to the main post now. Click on any photo to view the original size image!

Awesome, really cool. Trying it out today to see if I like it.
Another noticed bug - if you have a contact on your home screen (single icon version), which normally pops up the quick box for the contact, this now just seems to pop up their display picture and nothing else.

I see what you mean about the contact. It also happens when in the people app and you click their picture. I added it to the first post. thanks.

I thought changing the DPI would enable the ICS for tablets UI?

change resolution with rom toolbox?

So there's a setting inside ROM toolbox under build.prop tweaks. It let's you choose the resolution of the device. So this got me wondering if you can actually change the resolution of a phone or is the resolution of a device a limitation of the phone's screen. I know on computer monitors its really easy to alter the resolution and wasn't sure if a mobile device could function the same way. I tried changing the resolution from 720*1280 to 768*1280. It didn't brick my device but I'm not sure if it actually did anything.
Can anyone shed some light on this?

I don't think you can change the resolution
You can change the DPI but that's about it

Recent apps issue with DPI & Resolution change

Just flashed Lee 5.0 and on Oreo now and no issues yet and I finally decided to lower my resolution to 1080x1920 to see if it improves battery life. So far no change but I'll give it a couple days.
My issue is why are my recent apps previews and when I initially open an app it seems to open to a higher dpi then quickly goes to the one I have set. Also my lockscreen clock is bigger than my unlocked status bar clock and even the other icons like wifi, etc. It's not too much of a major issue yet but I'd like to see if there's an easy fix. Ive searched the 10 forums and also the rest of XDA to see if other phones have had this issue when changing doing but found nothing.
Also rebooted and cleared cache a couple times
Here's some screen shots of the kinda useless recent app - previews now

What are you changing your resolution/dpi with?
Should be zero negative side effects when using the settings > display > display size
options that are built into the native Settings...

Yes but that doesn't lower the resolution. I used a root app called "easy dpi changer"

Any way to make screen scaling smaller?

I saw the phone in a store today and wanted to buy it. But got annoyed that the smallest screen scaling option is still bigger than my p20 pro and feels like a waste of screen real estate.
Does anyone know of a way to make things on screen look smaller without rooting?

connect to adb and use wm size option. whatever size you set make sure aspect ratio is same as original device. it works better than wm density.

It’s even simpler than that. There are adjustments in display as well the option in developer options to adjust dpi.

You can change the minimum width setting to a higher number in developer options but it will mess up the SystemUI a little. Certain apps will become too large. It also resets every time you restart the phone. Huawei needs to fix this. It's one of the worst things about EMUI.

try using wm size. it works perfectly.
apart from some apps, like camera. use tasker to reset back when using camera

Thank you so much Guys! Is there any difference at all between using minimum with in developer options, and using vm size in adb? Cheers

It really doesn't work any better than using the Minimum Width setting in developer options and like you said it even screws up the camera app.

I'm using 600 DPI and I have no problems. I wouldn't recommend going higher than 640 as you might get glitches.

Does anyone have a link on how to use that wm size setting?

Font size reduction / Quick settings icons

Hello All,
1) Just as the title reads, is there a way to reduce the font size further than the lowest option from Settings > Display > Font size ? I just want maybe a little bit more. (PS: I'm trying to get the same font size and consistency as my OP7 Pro)
2) Is there a way I can change the quick settings icons's to reflect Google stock icons or Oxygen OS icons ?
I think for 1) above, rooting might be a way as i've done this in the past with my HTC phones. I havent had to root my last few phones but on the Note10+ the font seems to be absurdly large and its bothering me. My OCD is not helping either.
Any suggestions on getting around this will be much appreciated !

I like small fonts, and status bar icons, I set the dpi to 549 in developer option

Amazing, thats all i ever needed ! You saved me from rooting

Yes the only way to reduce fonts is to change dpi... but what dpi number is another problem..!

If you use the samsung keyboard, yes, a problem arises, as the keyboard becomes smaller when you increase dpi, I use AI type keyboard, it is not affected by dpi settings, appart from this I have not found any other problem

I noticed that, but it's much better than dealing with abnormally large text and icons everywhere. I'll probably use swift keyboard or keep tuning the dpi until I find a sweet spot.
