This is my first application. I appreciate any bugs or feature request you might have to be posted through a positive review rating and comment. In doing so, I promise to ensure this application will be updated to fit your needs and remain free of cost and any ads.
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.

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 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 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?
- Find and fix stuck pixels.
- Find and fix dead pixels.
- Repair the AMOLED burn-in effect.
- Find and fix LCD mura effect.
- AMOLED Ready.
- Unlimited blinking time.
- Totally free, without PRO Version.
The application will attempt to fix problems in the screen by stimulating the screen with a colour flash
To change the colours, use the volume rocker. No touch is needed.
Touch the screen to change modes.
Small gradient line on the top of the screen removed.
Can be installed on SD card.
NB: You can use this one for tablets, but for the best results it is better to download ScreenTest HD
This is a useful application for developers and the curious alike. This app does nothing more at this point.

# 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.
This app is probably only useful for android developers.
The launcher icon shows the screen density of the device, i.e. ld, md, hd, xhd, xxhd or xxxhd.
When the app is started it shows information about the display and display metrics. More specificly, it shows the information from:
Send the information displayed using e.g. email by selecting Share form the action bar or options menu.
This stop watch can measure 1/100 sec upto 9999:99:99'99.
The stop watch can run in background, quit without pausing clock,
the stop watch continue to count up.
In settings window, you can select font to display.
The paid version without advertisement, and have additional fonts
and alarm vibrator is available here.
* 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.
