The Instructions:
Short, sweet, and straight to the point: So, here's what you do... you will want to download the app called Screen Filter with the market link provided below. After you do that, within the Screen Filter app you will want to drag that brightness bar to say 85.1% and then hit enable. This won't lower your current screen brightness very much so no worries there. You should hopefully notice a difference for the better all around, especially viewing from an odd angle. It helps to reduce that white backlight look you get from a side view. I will typically set the in app brightness to either 85.1%, 75.5%, or 72.5%, and my actual system brightness to 50%. It works quite well without being too bright or too dark. And it goes without draining much, if any battery life. Feel free to try other brightness settings to fit your personal needs.

Try it on other Android devices as well, it works great! The best way to test it out is to use the widget. You can turn it off and on while changing your viewing angle to compare and see the difference for yourself on your homescreens. Forget about a complicated method and get yourself a better screen today with Screen Filter!

Screen Filter Can Be Found Here:
https://market.android.com/details?id=com.haxor&feature=search_result

Showing Off Side Angle View:
You will be able to notice that in the after screenshot the green bar across the top of the market app is quite a bit more vibrant and has more of a green color than the before screenshot. And you will also notice that the white back light color will be enhanced as well, giving a better appearance from the side viewing angles. A nifty little quick fix, if you will.

Before:


After:


Screen Filter Known Issues Reported By Users:
*Being completely stock and using the stock system apps seems to be causing some major lag issues (Xoom)
*Cannot seem to click install when you are manually installing an apk without disabling (Xoom)
*Cannot compose emails without disabling (Nexus S)

You can add to this list. If you find anymore issues please post them here and I will add them to my list above. After we gather most/all issues that we are having I will let the dev know what we have found and we can make some positive results for all! Maybe we can even have some new features added in a new release. Once the Honeycomb source gets released and we start getting custom ROMs, expect user interface tweaks such as what you find in Cyanogenmod. Until then, use this. It's the easiest and best tool we have for now. :)

Note For Screen Filter:
This method may only be effective on the 3G version of the Xoom. It appears that it may not be noticeable as much, if at all on the Wifi model.

Make That High Def Screen Even Higher:
For this you will need to be a root user, and always be sure to have a current Nandroid backup handy just in case.

You will want to download the free app called LCD Resolution (Root). You can find it on the market here. Open the app, and then you will see your current density setting as well a list of density options for you to choose from. The default density value for the Xoom is 160. I do not recommend that you go below 140, as certain screen elements may become misaligned. Just dropping the value down by 10 to 150 makes a nice noticeable difference.

Basically: The default density value for the Xoom is 160. I recommend using either 150, or 140 as your density value and nothing less. I think 150 seems to be right where most people would want their screen to be if they wanted to go just a bit higher def. It makes the resolution a little nicer without going too overboard. After you choose your density setting, don't forget to check the "Always Set on Boot" box. This makes it so much easier so that you will not have to worry about setting this up with every single time you boot. Then hit apply, reboot your Xoom, and then make sure that the settings stick. Done!

Apply one of the density settings I have listed with one of the Screen Filter settings also listed for a nice effect. It's almost as if you have a whole new tablet when you combine the two!

Currently: I am using the 140 density value on my Xoom, and I couldn't be happier! :)

Default Density Value 160:


Density Value 150:


Density Value 140:


If these tips have helped you out toss me a thanks. If I get more positive feedback I will be adding some more great helpful tips for us Xoomers. Thanks for stopping by! :)

im not really seeing a difference.
The difference is there. Try viewing from different angles instead of straight on and compare. I added my own screenshots of my Xoom just now and you should be able to see a nice difference from the before and after. This method really helps the side viewing angles a lot by reducing the white backlight that causes the screen to distort when not looking directly down on it. But it looks really great all around, not just from the side.

so what do i put the system brightness at? and what do I put the screen filter percentage at?
You can customize and set it to whatever you like. Me, for normal usage I like to use 50% for the system brightness and 85.1% for the Screen Filter brightness. I think it works quite well this way without being too dark or too bright. I use this setting on both my Xoom and my OG Droid.

wow, makes a huge difference for me, thanks
How does it impact battery usage at the 50/85?
It really does not impact the battery life very much if at all. In fact it possibly might save a little bit of battery life if anything. I've been using this setup for months and it has been working great.

my home screen n browser seems laggy when using it. Anyone has the same issue with me?
Hmm.. interesting. I use it all the time without any kind of problem. What launcher and browser are you using? And are you stock or rooted?

I'm using both Adw Launcher and Launcher Pro depending on my mood and they both work great with Screen Filter enabled.. no lag of any kind. And my browser of choice is always Dolphin HD and it also works without any lag. I'm on a rooted 3.1 Xoom with the latest tiamat kernel. Maybe I can help solve the problem?

i am curious why one would jack their screen brightness up to 85% in the first place, 33% gets a perfectly view able screen indoors. Not to mention the savings wrt battery life.
The 85% is for filter not brightness.

Yep, nice for off angles but for sure adds all types of lag. Bonse stock 3.1 no root. Factory launcher... isn't their a color control like what's available for the Nexus S? You would think with the screen wash out complaints someone would have come up with an answer by now.

Just tested another app. Really liked the effect on off angles so I'm searching the market for other stuff. There is another app called back light filter. It alowsyou to adjust the Alpha levels along with individual colors. Have to tinker to find the best fit but no home screen lag.

I've tested this app before and it's so so. Most users will want something easy to use without much tinkering or setup. It works pretty well through, but it could use some more features, it lacks a widget, and there is no notification bar icon for fast access. Good comment though. Maybe the people who are completly stock everything should give this a go since they are reporting lag issues.

I agree with you on the simplicity of the app in the original post. If the developer can dial out the lag it is definately the best tool for screen filtering on the xoom. I just wish the OEMs would provide simple calibration tools for screens.
