# You can do a backup of your configuration file and then restore it if you want.
# The app also backup automatically at each change the file, in a different file that the one you've manually backup.
# When apply, just use "Reboot device" to make change append (or it will be done at next reboot).
# Root Required !
# Please, mind to check "How To" and " Important" in the app, thanks.
# On some devices, the first try on «Apply» can fail, just press «Go» again and re allow root access.
The "Root DPI Changer" lets you change DPI of your device. This allows you to gain extra space to work (in case of reducing DPI) or increase the size of the elements (in case of increasing DPI).
- Changing the DPI by modifying the build.prop file,
- Creating build.prop backup files,
- Checking current DPI on system boot,
- Automatic DPI restoring (Experimental)
IF YOU NEED SUPPORT PLEASE EMAIL ME!!!
I try to respond to ratings, but it's a very slow and inconsistent process. Emails are immediate and I can push a fix for you right away. Lose your /system/build.prop? There's a backup in /data/data/com.oumugai.densityadjuster/, just copy it back from there.
Type in a new density, reboot to test it, and if you like the results, go back to the app and store it permanently. If you don't like the density, or something crashes, just reboot the device to restore your original settings.
I wanted a way to test different densities, but be able to reboot if the results were bad or broke my launcher and just have my old density back. This app does this, by simply restoring original build props during the boot sequence. It's not the most elegant solution, in fact, it's kind of gross, but it does mean you can change your screen's DPI while out on the town without ending up in a broken state (or having to bust out your laptop, USB cable, ADB and emacs you sad, sad person).
I don't like having to do extra work. You shouldn't have to either. Don't get stuck with a device with an unusable display.
You can write a review, and wait 24 hours or so for it to get to me, and then I can push a fix which will take hours to propagate. Or you can email me at email@example.com, and cut hours (or days) out of the equation. Either way, please report any issues you encounter. I typically can push a fix immediately.
Want new versions before they arrive here? Of course you do. Join the open beta on G+:
Want the source? No you don't. It's on GitHub, regardless of how you feel about it.
Things to do:
- Could (still) be prettier
- Notification if your current DPI doesn't match persisted
- Better su twiddling
- Disclaimers? Speaking of which...
THIS IS EXPERIMENTAL SOFTWARE. I WROTE THIS IN AN AFTERNOON. IT WORKS ON ALL MY DEVICES. IT MAY NOT WORK ON YOURS. IF IT DOESN'T WORK, FILE A BUG. HOWEVER, I CAN'T GUARANTEE ANYTHING. OK?
A particularly useful feature for developers is that it displays the configuration qualifier names that may be used to supply alternate resources such as layouts, drawables or strings.
For both users and developers, it shows you:
- The default display size in pixels (px) and density independent pixels (dip / dp)
- Reported density in dots per inch (DPI)
- For known devices - approximate physical dimensions of the screen in inches and cm.
For developers, it shows you some device details from the Android.os.Build class (MODEL, PRODUCT, BOARD, and DEVICE), and all the current configuration qualifier names in the order that they are used:
- Mobile country code (derived)
- Language (derived)
- Language / region (derived)
- Layout direction (API v17 / 4.2 and above only)
- Screen size
- UI mode
- Night mode
- Screen density
- Touchscreen type
- Keyboard availability
- Primary text input method
- Navigation key availability
- Primary non-touch navigation method
- Platform version
- The sizes are given for the *default display* - which is the area of screen that is usable by apps. On devices where there are soft buttons on the screen (i.e. back, home, and task manager), this will not correspond to the whole display.
- The xdpi, ydpi, and category densities are *as reported by the device*. These can often differ considerably from the true screen density for your device.
- Due to the density issue described above, the screen size (which is calculated from the resolution and density) is only given where the true screen density is known. If your device is missing, please provide the device name and the details shown in the "Device" section: Model, Product, Board, and Device), and I will add it to the database of known devices.
- Where the configuration qualifier name is described as derived (in the app these are shown in brackets), the device is queried for these values. For the others - the values are selected from actual resource folders using those suffixes (e.g. values-ldpi, values-xlarge, etc.).
NOTE: Sometimes SuperSU/Superuser forgets the app has root (even though it should remember). Just remove it from Recents menu and start it up again.
Resolution Changer is an app that lets you change the resolution of your device.
With the latest update you can now also change resolution whenever a second display is connected through HDMI! Experimental for now, but has been tested and working on some devices.
Ever connect your device to your TV or monitor and get black bars? Not able to get full resolution output to your TV? Well IN COMES Resolution Changer! With this app you can set your own resolution to fit your second display or monitor. It has both 16:10 AND 16:9 aspects!
This works independent of device! Tablet or phone; it doesn't matter.
Do you have an old device that won't play your newest games without significant lag? Again Resolution Changer can help you! Set your resolution lower to be able to play the LATEST and GREATEST games! With Resolution Changer, playing the latest FPS, racer, whathaveyou, will be no problem.
####### THIS APP REQUIRES ROOT AND 4.0+ #######
####### TouchWIZ launcher will behave oddly -- install an alternate launcher BEFORE trying this #######
####### Android versions LOWER than 4.2 may not fill the whole screen. #######
####### HTC devices without physical buttons may lose the use of its buttons (use on-screen nav keys instead) but will return when you reset the resolution back to normal. HTC One cannot install this app #######
HTC One has been excluded due to the digitizer being bigger. Touch-buttons get turned off even when reverting back to default resolution. Also reported on HTC Sensation, but the Sensation is left included because it returns to normal upon changing back to default
* Density of this application after changing some equipment may not be able to see properly. *
You can change the DPI of the application helps you more quickly and easily.
Enter a value in the input box to the desired DPI, then the Apply button or the Apply button to apply and reboot is complete!
In addition, when you click More button, the unit reverted to type after the change DPI mount features discomfort when you can return it back.

- Gamers: Some games feel choppy? Decrease the resolution while you play to improve performance significantly.
- Developers: You can test your application UI for different devices by changing resolution and density to match your target devices. The application provides many templates for flagship devices to select from.
Two Android shell commands control screen resolution and density (dots per inch):
For Android 4.3 and higher, these two commands were moved from am to wm. Now they are:
This application nicely wraps these two commands so you can try different settings quickly and easily. It doesn't implement these functions, it merely uses them. So, if they don't behave well on your device then there is nothing we can do about it, please don't rate us down. We are just trying to make things easier.
- This application is not intended to change your device resolution and density once and for all. Use it only when needed then restore the default settings.
- When applying new settings, if things get messed up, don't do anything and the normal settings will be restored in a few seconds.
Some launchers don't feel the changes immediately and may show broken icons and other visual artifacts. Restarting the launcher manually should fix this. Some home screen icons may cover other icons due to lack of space. Try moving them around to reveal the covered ones. Some hardware vendors design their software to work with the devices' native resolutions and densities only. If you experience problems, consider installing different launchers and keyboards to fix the issues.
- If your device doesn't have hardware buttons and depends on on-screen controls, the controls may have problems on certain resolutions. They may appear in both portrait and landscape orientations or only one of them. Try increasing the size of the smaller dimension a bit and they should appear in both orientations. Otherwise, you can just enable the virtual buttons and ignore the entire problem.
- Choosing resolutions with the same aspect ratio of you device's original screen resolution maximizes the usable screen area.
- If you are using a mobile phone, the width should always be the smaller value of the resolution (width, height) pair. If you are using a tablet, the width should always be the larger value of the resolution (width, height) pair. This allows the resolutions you select to cover the largest screen area possible. You can still do the opposite, but then less screen area will be used to display your applications.
- The display resolution isn't the only factor affecting games' performance. Reducing resolution will significantly increase the frame rate up to certain limits, after which further reduction will not produce notable differences. For example, here are the results of nenamark 2 benchmark of a certain test device:
34.1 fps at 1280x800
41.2 fps at 1024x640
47.0 fps at 800x500
49.0 fps at 480x300 => the pixels count decreased dramatically from 800x500 (64% less pixels), but achieved very little performance gain for the huge quality loss. Experience with different resolutions until you find the best trade-off between quality and performance.
- All templates are based on information from gsmarena.com. Tell us if you to add a certain device to the list.
This tool gives you the ability to change your screen resolution, density (DPI) and overscan.
Why do I need to change my resolution?
# HDMI / TV-OUT / MIRACAST:
You want to adjust your screen resolution to fit your TV or External Monitor which is connected to your HDMI output to get rid off the black bars? With Resolution Changer, you can set your resolution to fit perfectly to the external monitor.
Additionally, with the HDMI Auto Resolution feature enabled, your device will detect your external HDMI Monitor and sets the screen resolution and density automatically to a chosen preset.
With overscan set, you can adjust your screen output padding to match excatly the External Monitor.
You are developing apps and you want to test your app on different devices? Just use a device preset or create your own one to simulate the screen resolution and density of every possible device.
Your device is too slow for the latest games? Just change the resolution to a lower one and enjoy your games with a higher framerate.
If the device has problems with a choosen resolution, the default one will be restored after some seconds. Some apps like the launcher or the keyboard might not always scale correctly with every resolution.
The application is still restricted to the technical conditions of the device. That means, you wont be able to choose a resolution your device is not capable of displaying.
This is a useful application for developers and the curious alike. This app does nothing more at this point.
