This will NOT trip Knox.
You can change DPI without root but will need to use adb on a computer.
As some of you may be aware, changing dpi in build.prop does not work, therefore I have also now included a method to change DPI with root, without the need of a computer. Scroll down to see how to do this.
Since the April update, Samsung have included a menu in the settings screen which allows you to change between 'Standard' (640 DPI) and 'Condensed' (560 DPI). If you have not had this update, you can still access this menu using this app.
(AT&T users have confirmed that this menu is not available in the display menu but still available via the the app route.)
If you would like a different DPI other than 640 or 560, please follow the instructions below:
Change DPI without root (Requires Computer):
To do this, follow the steps below.
- The first thing you need to do is to install adb. The quickest way to do this is using the adb installer. You can download it from Here. If you follow the steps correctly in that thread, you should have no issues installing adb.
- Now you will need to enable USB Debugging. [If you have 'My Knox' installed, you will not be able to do this so you will need to uninstall 'My Knox' First otherwise USB debuggin will be greyed out.]. Go into Settings > About Device > Software Info and keep tapping Build Number until Developer Options is enabled. Then go back into the Settings screen and go into Developer Options (located just above 'About Device'). You should see USB Debugging, turn the slider to on.
- Connect your S7E to your computer. You will see a notification asking for you to Allow USB degugging for that computer, select 'OK'.
- Now open Command Prompt (CMD) on your computer. (If you're not sure how to do this, Click Here to find out how).
- First thing to check is if adb can detect the device, so type the following command in CMD and press enter...
- If this command shows the device (a line of random letters and numbers), then it has successfully detected your device. If nothing shows, then it cannot detect the device and you have either not enabled USB debugging, not allowed USB Debugging for this computer (as per the prompt when plugging it in)or the drivers have not been installed. (Most recent Windows will automatically install the Drivers, but if you are having Driver issues, then install Kies, connect the device to Kies to allow the drivers to install, then remove device from the computer, disable Kies then start again from Step 3).
- If the device is detected in adb, go ahead and enter the following command to change your DPI. 560 is the most commen used but you can change this to anything you like (I find 520 to be the best).
adb shell wm density 560 && adb reboot
- Your S7E should now reboot and the new DPI will be applied. To confirm this, install DPI Checker from the Play store. The prop file will still show the default DPI of 640 so ignore this.
If you want to revert back to the default DPI, enter the following command:
adb shell wm density 640 && adb reboot
Change DPI with root (No computer required):
1. Download a Terminal app (such as this one) and open the app.
2: Type the following:
Then tap enter. This will prompt root permission, make sure you allow permissionCode:su
Change 560 to your prefered DPI.Code:wm density 560 && reboot
Then tap enter.
3. Your phone will reboot and when booted it will have the new set DPI.FAQ:
4. To change back to stock DPI, use the following in Terminal:Code:wm density 640 && reboot
Will this affect Samsung Pay?
No. But I recommend you make sure the initial Samsung Pay set up is complete before changing DPI as some people have reported that the initial set up does not work after changing DPI. After that it works fine.
Will this affect Android Pay?
Yes. You will not be able to use Android Pay after changing DPI
Will this affect the scaling of Samsung apps?
The camera shifts slightly to the left.
Using the stock wallpaper will leave a blue gap at the bottom of the lock/home screen.
The Edge screen will have a small gap at the bottom.
Other than this, I have not noticed any other scaling issues (see screenshots below).
