Touch panel type - EVO 4G Q&A, Help & Troubleshooting

Can someone please tell me how I can tell which type of touch panel I have

It says it in the bootloader menu at the top.
We're comin from a pure power source.

So did you find it?
We're comin from a pure power source.

Also there is some command you can type into terminal emulator to tell if you have a novatec or Epson. I don't remember what it is tho...

If your screen dims by fadding, you have novatec. If it just jumps levels, Epson

Use the brightness widget and place it on your home screen
click it - if your brightness fades slowly (where you can see the transition) you have a novatec
if it jumps meaning when you click the button its instantly brighter or darker you have an epson

how do i know what panel my phone has? my friend and i both have 003 but there are obvious differences in the screen, how can i find out if i have the epson or novatec?

sry bout that thanks for the link
not a problem
for those that dont want to read the thread, or do the adb work..
the easiest way to see what screen you have is by using the power control widget, and pressing the brightness button.
If your screen fades between brightness, you have Novatek. If the screen brightness changes instantly, its Epson.

ScreenDim

New on the Market:
https://market.android.com/details?...mkub21lZ2FjZW50YXVyaS5TY3JlZW5EaW0uVHJpYWwiXQ..
"Is your minimum screen brightness still too bright? Dim your screen below what your device normally permits for comfortable use in darker environments, reading in bed, amateur astronomy, etc.! No root required."
I find this app indispensable for comfortable reading at night.
Thank you so much for this, I was just thinking last night that even the dimmest setting on the A100 was still to bright

I'm the ScreenDim developer. Screen Filter is free and clever, but it doesn't do the same thing as ScreenDim, at least not on LCD devices. Screen Filter basically just alpha-blends a dark box over the screen, without lowering the backlight level below what the OS normally allows. The result is that Screen Filter lowers the contrast and the color resolution, and in a dark room, the blacks will be gray because of the backlight shining through them.
ScreenDim allows you to both lower the LCD backlight level below what the OS normally allows on many devices and, if that's not good enough, to control the contrast just as Screen Filter does. Furthermore, because ScreenDim allows you to lower the backlight level, it will save on batteries in a way in which Screen Filter will not, again on LCD devices. (On OLED devices, there is much less of a difference.)
Moreover, my testing on my Archos 43 indicates that Screen Filter lowers the 2D rendering performance by about 30%. ScreenDim at 100% contrast shouldn't affect the 2D rendering, and even with the contrast adjust, I couldn't measure a noticeable 2D performance loss.
For real free alternatives to ScreenDim on backlit devices, there are AdjBrightness and my RootDim, both in the Market. Both require root, however. And ScreenDim's dual brightness-contrast adjustment feature is found in neither.
+1 for root dim, I use it and it works well on this tab and my atrix
be careful not to set it to 1 because its turns off the screen but the tablet is still on. i got stuck trying to find the slider to slide it back so i can see the screen again. nice find though.

Tapping random places on the screen should quickly restore the brightness.
Also, if the tablet has volume buttons, you can adjust brightness with them.
Once you figure out what the lowest you can go is, go to Options | Set minimum brightness. Then you won't have this worry any more.

Love screen filter it works great and its free, super simple, plus pop notification bar too. Awesome app. Screen filter is

ahem. I'm not sure exactly where those buttons were when I needed them to try to get the brightness restored, but I couldn't find them on two occasions. I had to hard power off.
Great idea but it won't work for me unfortunately. I want something that will turn my tablet into pure darkness except for a small, dimly illuminated, clock on the screen. No matter what I find, an app always has too much backlight on and it bothers me when I'm trying to sleep.
If only I could get this app to interact with my alarm clock app somehow!
Status bar
Is there any way to remove the status bar icon of the ScreenDim?
I thought the app was designed to reduce distraction while using a device, but the icon being in the most prominent spot (upper left corner) draws attention constantly.

Screen Backlight ??

Hi
I was wondering if there was an app with which i can turn off the backlight like when u click on clock app and put on desk clock mode by tapping or few secs before the screen goes off ??
is there way to toggle that ?
What exactly do you want to do? turn down brightness when on desk clock? that is already done automatically as far as i can tell.
AMOLED screens don't have a backlight. Each pixel has it's own light source. That's why the blacks are so black, the screen is actually off in black areas.

The clock just makes everything darker. The GN doesn't have a backlight anyway, as it's a (super) amoled screen.

AMOLED/OLED screens also burn when left on the same image for a long period, would not recommend using as a desk clock as stated in OP, you will end up with burnt images where your buttons are, and any other static part of screen

The are a few brightness toggle widgets available, android comes with one built-in, power control allows customization of the brightness level so that you can go say from Max brightness to min brightness in one tap. Rom Control in the Android Open Kang Project allows for adjusting the brightness, order, and number of navigation bar buttons independent of the overall screen brightness.

ScreenDim 1.10 beta -- need testers

I apologize if this violates forum rules.
ScreenDim is my (paid) app for dimming the screen beyond standard OS settings. On OLED devices, it basically does what ScreenFilter does, but I think in a rather more friendly and useful manner, including pre-sets. (On LCD devices, it's much better than ScreenFilter, as it actually dims the backlight, thereby improving contrast and battery life.)
I just finished making a beta of ScreenDim 1.10. The main new feature is Easy Mode which combines the brightness and contrast sliders into one. Currently, Easy Mode only works on Galaxy S2 (including Epic 4G Touch and other versions) and Kindle Fire. You can toggle Easy Mode with Menu | Settings | Easy Mode.
I'd be grateful for any beta test results. To the first ten people who send me useful reports, I'll give give free copies of the paid ScreenDim 1.10 once it's released, as well as free copies of my LunarMap HD and Force2SD apps, if you want them. (Alas, I don't have a gift-code setup arranged, so the free copies won't auto-upgrade.)
I would be more than happy to be your first beta tester!

Buggy at times, when at 0% it doesn't work with volume keys --- only min: 0.0% and Max 0.1% when put down to 0.0% with volume keys...
Same applies when pressing min (highest will go to 0.1% when holding volume up and repeatedly hitting volume up...)
When screen is too low a dialogue should pop up saying if you do not confirm this brightness within 15 seconds, it will go back to your last setting...
There should be an option to disable notification icon (not invisible, just not at all) totally when using and/or not using the application.
A more detailed About/Help menu would be more useful...

If I've helped, I am interested in free paid versions of your apps... I believe that if you send a check in the mail after the person buys the app as reimbursement would be more easier than consistently updating via email. (Not to overstep you or anything, just a suggestion.)

App works as promised. Some screenshots attached.
Suggestions: have way to disable notification icon.
Also when not in easy mode the lowest you can go is 11.8 on both sliders. Not sure if that is design or a bug.

When did you download? I think I fixed that problem around midnight last night and uploaded a version with that fixed. (But I forgot to mark a version number.)

Can't be done without sacrificing reliability. Unless you do something root-ish (and I really want this app to be non-root), the only way I know of keeping an app from being killed in low-memory situations is by using Service.startForeground(), but the OS requires a notification icon when you do that.
Also when not in easy mode the lowest you can go is 11.8 on both sliders. Not sure if that is design or a bug.

If you want, you can make the brightness slider go down to 0.4% by using the "Set minimum brightness" menu option. But you will find that below 11.8%, the brightness stops changing, so there is no point to that, and that's why I set the default minimum for the Galaxy S2 series to 11.8%.
You could make contrast go below 11.8%, but the display would probably be dimmer than anybody wants (I am about the pickiest user in terms of darkness, because I am an amateur astronomer, and I don't want the device to destroy night vision), and the display quality would be low. Unfortunately, given how OLED devices work, at low brightness levels there are much fewer colors available.
Technical stuff in case anybody is curious:
The way Easy Mode works is that 30% on the Easy Mode slider is equivalent to 11.8% on the brightness slider and 100% on the contrast slider. When you go above 30% in Easy Mode, you're increasing brightness and keeping contrast at 100%. When you go below 30% in Easy Mode, brightness stays at 11.8%, and contrast goes down, hitting 11.8% when the Easy Mode slider is at 0%.
On LCD devices, the brightness slider controls the backlight and the contrast slider controls the white level (by drawing a gray rectangle over the screen). On OLED devices, both of them have a similar visual effect, namely they both reduce the intensity of the miniature LEDs that make up an OLED display. But at low brightness levels, you have fewer color intensities available on the physical display.
Works great. I have been waiting for this so I don't have hear the wife complain that my screen is too bright at night and keeping her up.

everything works really well, tested in easy mode... only issue was the " + " button didn't work the first time I pressed it, and the n I pressed " - " and they both started working again. I could not get the issue to happen again, don't know why it happened the first time.
works as expected. only problem, and perhaps this is intentional, is that if you change the brightness in the android display settings (as oppoposed to the app), then it goes back to the standard android brightness scheme. in other words, the app and android settings dont seem to correlate with eachother? lemee try to give you an example...
i go into android display settings and change it to 100%. then i go into your app and set the brightness to 0%. this dims the screen down tremendously, which is exactly what i like. okay, now if i go back into android display settings (still leaving the app still at 0% with ultra dim display), and lower the android screen brightness setting to say... 95%, the app seems to disable or something and the brightness will jump UP to android's 90%. instead of the display getting further dimmer, it instead shoots back up to almost full brightness when it should be going down. i hope that makes sense.

Right, the system settings partly override ScreenDim's brightness setting. I can't lock in the settings without root.
this app rocks man, thx
I found a bunch of bugs when using "Quick activate" and loading presets and changing settings starting from a disabled state. I fixed the ones I found in 1.10c (now up), but there may be others.

Yup. Notice it in YouTube videos. A line all the way across where the soft keys end and sometimes you can see the outline of the home button.

What colour home button have you used the most? Blue by chance?
White.
However I understand blue pixels die/burn easily.

It's not technically burn in. Think of it as reverse led fatigue The leds that make up the navbar are burning brighter due to less time on them and where you can see the button images is where the leds have been used. On the first gen galaxy's some would make entire screen white and put it at full brightness and let it sit on overnight.
good day.
We've posted this many times, yes the screen gets burn in. That's why I hide the top and bottom bar each day to use those pixels frequently. I also reduced the height of the buttons. My burn in is basically gone.
I know the screen burns in. This thread isn't about a new discovery. This thread is about what I should do about it. I disabled the soft keys and am using LMT Launcher now.
I'd like to use the normal keys, but want them to hide. Like how the task bar in windows will hide. Any apps you may know of that do said feature?

SAme problem here... I have some icons ''burned in'', im trying a 10 hours white screen youtube video now, maybe it will work.... You guys have other ideas?
I can recommend using Display Tester by gombosdev Its free and supports ics fullscreen option in settings. Use the dead pixel test to display a single color. I got burnin for red only for the pixels that have not been 'exercised' top and bottom.
I was expecting burnin eventually but not that the 'black' pixels would burn in and certainly not that the red color would be affected and not the blue.
I started seeing this after only a few weeks

Sounds more like a result of dead pixel.
Cause of the nature AMOLED's working, a dead pixel causing an entire line of pixeld distorting and then dead after some time.
P.S. Oh sorry, its not, readed it wrong
Yeah I hide the bars once a day. Also I make my button color green, and signal and click etc green since that is the most robust color, and also green text looks sharper since there are twice as many green pixels as blue and red. So it looks good too.
How bad it is, when I have a lot of blue on screen? How long it can last ? And is damage permanent? Stock JB has quite a lot of blue pixels and I would also like to use some themes like http://droidviews.com/2012/iphone-4s-ios-theme-for-miui-v4-update/
Does any ROM have the ability to set white notification and soft-key areas? I'm very keen to try and even out my reverse burn-in problem.

For notifications and the soft key bar, I believe you would have to use a theme. The only rom I know that has nav bar coloring abilities built-in is Codename Android.
