If you are having a problem or you have a suggestion about a missing feature, the ONLY way it will get done is if you email me! :)
Do you need to check your phones LCD screen for dead and stuck pixels. Usefull especially when buying used phones. Install this very small and simple app. This application will cycle colors that will be able to display non-working pixels.
Tap the screen to view next color or to stop color-cycling when it is running.
Stuck pixels are often incorrectly referred to as "dead pixels", which have a similar appearance. In a dead pixel, all three sub-pixels are permanently off, producing a pixel which is permanently white for TN panels and black for other types of panels. - Wikipedia
Disclaimer: This application will not fix dead pixels. Due to different LCD manufacturing techniques and technologies, this application does not guarantee to fix all found LCD problems. The fast color transition effects may potentially trigger seizures to people with photosensitive epilepsy. Viewer discretion is advised.
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 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. IT RELIES ON SYSTEM SCRIPTS THAT YOUR PHONE MANUFACTURER OR CARRIER MAY HAVE ALTERED OR REMOVED. NO GUARANTEES.
This app serves two purposes:
1. Your fingers touch a portion of the screen, but the touch screen only registers a single pixel. This allows you to see exactly where your device registers your touch.
2. Find out if there are any areas that do not register your touch. For example, your device will likely not register the far edges of your screen.
* Touch anywhere in the black screen.
* The EXIT that appears on the left in random spots can be touched to exist the app if you don't have physical back or home buttons.
* The back button can be used to exit the app as well.
* The Flashlight you will never forget to bring when in need!
* With the most elegant design and the fastest startup
Main features :
• The brightest illuminator ever
• Fastest startup flashlight
• Strobe mode with sensitive frequency controller
• Built-in SOS flashlight signal
• Intuitive and elegant UI design
• Use the cam LED light!

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)
