How to make your Android device's screen look less or more zoomed-in by changing its PPI value

How to make your Android device's screen look less or more zoomed-in by changing its PPI value
Say, ever used someone else's Android device for a while, only to come back to yours and get the strange feeling that the icons and text are way too big, or too small? Curiously, users of the Sony Xperia Z3 and Z3 Compact have discovered that they get to see the same amount of content on each, even though the former measures 5.2 inches by diagonal, while the latter is just 4.7 inches. It's not your vision, there might is a real problem there, and it lies in how your device's manufacturer decided to scale the content shown on its display.

Take the LG G3, for example - its display's native pixel density is 534 pixels per inch, but LG artificially set the value at 640ppi, which makes everything look big and zoomed-in. Although it looks perfectly fine, you are not getting the most out of the screen's spacious 5.5-inch diagonal. By reducing the ppi to 540, a value that LG G3 modders consider very comfortable, the available screen real estate is utilized more appropriately - icons are less cramped, you can see more lines of text, and it feels like your display grew a little bigger! Here's a before and after comparison:

The best part is, you don't have to do anything complicated to change your display's pixel density for the better. You aren't losing image quality either, although some UI elements might not scale correctly - in this case, it's the app drawer button. Still. here are the steps you need to take:

- Download and install Minimal ADB and Fastboot v1.1.3 for Windows - download here.

- Enable USB debugging on your device. And if you haven't done any modding on it before, find and install an official Windows USB driver from its manufacturer.

- Connect your device to your PC via USB cable. Then start Minimal ADB and Fastboot from the desktop shortcut. Type "adb devices" (without quotes) in the command prompt to check if adb recognizes your phone. Don't worry if you get a server or daemon error message.

- Use this pixel density calculator to find out what your device's native PPI is.

- If your connection is alright, type "adb shell wm density n" (without quotes) where "n" is the pixel density value you want to try. You can start with your screen's native value, which will probably make everything tiny. So try increasing the number from there and see where that takes you! Mind you, the change will disappear when you reboot your device.

It's the same. DPI (dots per inch). PPI (pixels per inch). In a screen, one pixel is one dot.

i want to ask because i dont understand, when i did google a long time ago, ppi = dpi, but the spec said Note 4 has 520 dpi, but when i use resolution changer app and some device-info apps to check, they said 600+ ppi , why?

No, it's not the same. A dot can have more or less pixels.

You can kind of do the same thing in Nova launcher (and most other launchers) by choosing more or less columns and rows and by changing the icon and label size. Just saying.

Yes, but that is not device wide. That only affects home screens and app drawer.

Yeah, but pinch-to-zoom basically takes care of the rest.

I use ES file explorer to set DPI in build prop. Adb way can be done without root I believe. Otherwise yes it's needed

Permanent change to DPI need root. Edit - /system/build.prop Set property to whatever value you want, ro.sf.lcd_density= I have made this modification to my Oneplus One...default is 480 and I have set it to 420. This simple change makes best use of 5.5" screen.

I'm still trying to find the real difference between ppi\dpi and resolution for android. Ever drop your resolution for a faster framerate on your computer? It's the opposite with dpi. It's counter intuitive. I think chainfire had an app for that before. Can anybody recommend am alternative?

Chick on the wallpaper on the right is looking mad sexy in those Air Max 90's.

I personally like the bigger icons (Google Now Launcher, etc.). I've never been a fan of large, high-res screens with tiny text and small icons. It almost defeats the purpose of having a larger screen.

Did this on my s5 with stock TouchWiz and the fingerprint was not in line with the home button, there was unusable space above the dock and the stock gallery app was messed up.

That's a lot to do just to change the ppi. Should be able to it in settings like on a computer

So that's why iPhone screens feel bigger than Android screens. Not anymore :)
