[TIP] How To Enhance Screen Quality For Xoom [Updated: 9/5] - Xoom General

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.

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!

Thank you for a great tip. My Xoom screen look better now. This is why I love to visit XDA everyday.

Will check with Acer A500.

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.

I see what your saying, the viewing angle is alot better now, thanks OP

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.

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.

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 don't see any difference.

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.

[Q] Dark screen app (?) to reduce brightness? Is it possible?

Hello
I have a Samsung I9000 Galaxy S which is way too bright even at the lowest setting.
Anyways so I got an idea of an app but I dont know whether its technically possible or not!
So is it possible to create an App that works just like a transparent dark glass which covers your screen and you see through it and can perform all functions normally but due to the app the screen becomes dark so that it doesn't strain the eyes?
Also current "minimum" brightness on the Galaxy S is "10" even with 3rd party apps. Is it a limitation of Android or Samsung firmware? Also is it technically possible to go into - values such as "-30" ?
Ah, great topic. I have the same problem on my HTC Desire. Interesting to hear what the experts have to say.
Yeah these amoled screens are uber bright!

I have read on the net that it doesnt work for Galaxy S.
The app is called screen filter. Don't really know too much about it other than it works fantastically well and its free. Reduces brightness to almost nothing if you want, and the app functions as a widget for toggling as well.
I've been going around posting this in as many places as i can because this freaking app really helped me out, I could hardly look at the screen in the dark at all but now its good to go. Hopefully help some new galaxy purchasers out.
You can't go into minus values but you can set it to 0, which is 1 above the screen actually being off.
You need to be rooted, then you can just adjust the value with adb.

Power Consumption vs. Screen Density

I'm in the middle of doing a major 'power overhaul' and was wondering if scaling the screen density from 240 to 160 would hurt/help my quest.
Attached is the basic density, and of course i try to keep dark colors or white on black themes. Obviously not done yet.
I will say this... In my experience, on my own phones and others (many others at work I have rooted), that task killer will drain you worse than anything.

I tweaked my build.prop file to reflect 160 density, and haven't noticed any significant battery save.
However (as noted in a previous post), changing the density in our build.prop files as of now seems to cause all sorts of clusterf*** with many HTC apps (people, calculator, mail, footprints, peep). I haven't figured out why that is, and for now I've just replaced them w/ 3rd party apps because I can do without them for the sake of having the LCD density I want lol.
Hopefully one of us lands on the answer of how to mod the build.prop w/o causing numerous HTC FC's in the process.
Agreed with the HTC apps, I went 3rd party too. Most have similar (if not better) functionality. Thanks for actually getting back about my op.

Np.
BTW, I tested out 140-180 densities, and 170 seems to perform the best on our phones in terms of widget responsiveness, while maintaining a clean pixelation. I also keep the brightness @ a cool 20% (unless i'm in bright sunlight). No complaints so far.
Oh, and "contapps" from the Market = what the HTC "People" app should be. Check it out.

[DISCUSS] Screen brightness sensor a joke!!

Sending this straight back, I cannot believe there is no option to disable auto brightness settings on this heap of ++++.
It has got a mind of its own and is extremely annoying to suddenly see the screen get dim and bright every 5 seconds without any change in actual lighting condition...it makes the phone almost unusable.
Hope someone can make a hack for this soon.

It's not a "software bug", it's SE dictating to us that in order for the paltry battery to last a day, we need to use it in the dark, or disco mode!

It does have Auto Brightness as if you put a finger over the light sensor the phone screens dim.
The phone had an update pending the day I purchased it so most of the reviews I have seen are out of date. This phone is excellent at playing games.

I hear that. In love with my Xperia Play.
Guys can someone tell me. A lot of reviews say that the screen is very dim even on max setting and a lot of reviews say the exact opposite. So what is it?
Mine is perfect in the sun. I'm starting to think there are 2 types of screens involved, anyway to check what screen you have without opening the device up?
Screen brightness is ok for me, but just remarked the display have some ghosting issues. Slide beetween programs screens and observe carrefully the icons.... with red "Adresse" one this is very visible. i can't belive sony use a high response time display on a gamer device.

Having problem with auto brightness

I got note 3 days ago. I notice that The brightness always jumping, sometime happen with open application with white background.

I got the same kernel but without the auto brightness jump you are experiencing, unless I move my hand over the camera.
I suggest goto Settings --> Display and un-tick "Auto adjust screen power" if it's on and see if that makes any difference.
Auto-brightness is hopeless anyway, turn it off, as well as the setting Bigmile mentioned. Then, to make quick on-the-fly adjustments to your Note's brightness long press in the notifications area and slide left and right till you get the brightness you want. Much better way IMO.

Poor Samsung. First, everyone *****ed about the panning box they used to allow you to move through a note you're working on. Then, they changed it and replaced it with a scroll bar and people are *****ing about that too. I don't know which version of S-Note you're on but in the version included in JB with "only recognize the S-Pen" enabled it's really really hard to inadvertantly hit the scroll bars so maybe that'll solve your problem. As for the brightness being ramped up in S-Note I get the logic and it shows how much they think about how people use their devices and apps. If you think about, since the Note's a drawing device, people could be using it at any angle and in any position. Disabling auto-brightness kind of makes sense so that the screen doesn't fade in and out if someone's hand is over the ambient light sensor. Oh well, you can't please all the people all the time.
"version included in JB"
Jelly Bean? I thought the US Note 10.1 were still in ICS

Doesn't mean that you can't flash another rom...
I don't use autobrightness so it changing the levels drives me absolutely nuts. E.g. I'm working in a dark room so have the level turned down to what suits me best. I open snoteb and up it goes. I turn it back down manually, jump to another app for a moment for whatever reason, say to read some info in a pdf, switch back to snote and, bam, blinded again.
There's a reason why autobrightness can be toggled on and off, and one app ignoring that convention is infuriating.
actually if you use autobrightness, the brightness levels still change
"Disabling auto-brightness kind of makes sense so that the screen doesn't fade in and out if someone's hand is over the ambient light sensor. Oh well, you can't please all the people all the time."
If this is the case, then there are definitely better solutions than the one Samsung implemented. For example, putting a timer on the ambient light sensor so it doesn't react to accidentally being covered up. If it's only briefly covered up, the brightness won't change. If it's really in a dark room and sensing low light with no interruption for say 1 minute, then change the brightness.
So, it's hard to believe that Samsung would make SNote change the brightness autmoatically as a "feature". Samsung makes great products, but we dont have to idolize them the way that iOS Sheep idolize Apple.

If you're referring to me I chose the Teg3 One X over the SGS3 and am very happy with my choice. Here's a demonstration of my lack of idolization. In JB, putting the multiview selector to the right of the more important and more often used "settings" selector wasn't very well thought out from a usability perspective.
S-Note turning up the brightness works fine for me and I kind of like it since auto-brightness tends to be on the dim side normally. I'd probably like it less if I frequently took notes in a dark room which I don't. I don't assume everyone uses their device like I do so I certainly wouldn't invoke my opinion of a feature on others.
This is why I use lecture notes.
There is no brightness ISSUE.
They increase brightness on purpose to make drawing more precise.

You can't upgrade or downgrade S-Note with just the single APK. There are supporting files that have to be changed along with it. When PDF import was borked on some versions of S-Note folks tried to update it with a newer version of the APK alone and it failed.
Actualy, I did the backup with titaniun but when I tried to restore now I am getting FC. Any idea how can I fix it then?

Yes they can, they can let us make up our own mind as to what level of brightness we want, the same as we do with every other app. Why bother having a brightness setting at all if that's the case, just get rid of it entirely as they know better.
