REQUIRES ROOT! AND ANDROID 4.x!!!!!
The init script it relies upon doesn't exist on Android 5.x, so either I have to fix it, or you can submit a pull request on GitHub. Don't expect it to work on 5.x.
IF YOU NEED SUPPORT:
I try to respond to ratings, but it's a very slow and inconsistent process. I check the email as frequently as I can, 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 firstname.lastname@example.org, 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...
