Is there a way tio get a clock in the screensaver? my just turns totally black.. in my old nokia and SE it was possible to put a clock in there.. i have tried but cant find anything about it.. / Jörgen
It's not a screensaver, that's the screen being turned off to save battery. My guess is that on smaller screens the power drain involved in displaying the clock is quite low as the backlight wasn't on. On the screen on the hero (and pretty much every other colour screen phone brought out in the last 5 years) the screens need to be backlit to show anything and the power drain would be huge.
In short, there might be an application to do it but you are far better off just pressing the on button when you want to see the time.

Really? Why is that?
Modern LCDs all have a backlight and the image you see is obtained by filtering this light through individual switchable filters (these make up the pixels). In the past some screens worked by varying how light is reflected from the screen using these filters but these are inferior to modern lcds. We are now seeing a return to non-backlit screens with the new OLED technology but this is still actively lit at the individual pixel level.
If you don't believe me then take apart a laptop or LCD screen and disconnect the power inverter which is responsible to supplying the power to the backlight. The screen will appear to be completely dark unless you shine a very bright light on it and then you will be able to see the image very faintly. Just don't do what I did and snap the inverter, felt very silly.

I really like the GTX version of NRGZ28's CHT rom, but it strikes me that with all that wite in the screen it will use more power.
Can anyone confirm that's the case?
cheers
hmm maybe I missed something but why would a color cause more battery drain.
you could also use the leocpuspeed to unclock your cpu thus saving some power.

Technically, your assumption is not correct. Your HD2 comes with an LCD, displaying the white color does not affect power consumption here.
In an LCD, the backlight is always on when contents are displayed - power consumption is only reduced if you dim the backlight, or the device goes into standby mode.
In a simple description: The LC molecules actually turn like a shield to let the backlight through or not. Each pixel on the screen is divided into three subpixels (red, green, blue) to produce the colors.
If one pixel (eg all subpixels) gets the full shield, it shows black - but the backlight is actually still on.
In the sum: Maybe the power consumption with your new theme goes up just because you look at it more often... isn´t that a funny side effect?
From my understanding of how LCD screens work the backlight is permanently on and energy is used to block the light coming through the colour pixels thus more energy is used to produce a black screen than a white screen!

That sounds interesting. Any source for that?
makes sense (no pun intended !), for some reason I had it in my head that these were amoled screens.....wishful thinking I guess!
Yes, black uses more power on this type of screen (on a CRT it's reversed, the black uses less power than white). But you won't notice any real gain (a few minutes a day at best) since the power hungry part is the backlight, and because when the device isn't in standby you are probably using it (I'm not someone who look at the home screen and do nothing more all day, and don't know anyone doing that ). 10 minutes of web browsing will use more power even on a white background than 30 minutes of full black home screen.
My screen dims in programs like mail and explorer when i open them. I have it on high and auto off but it dims whenever i go into these programs. The home screen and everything else stays bright. Is there something i am missing.
I'm talking out my ass, but the only thing that would make sense is that it's a "safety measure" because all white screens kill OLED screens, like what the Focus has.
I called Samsung about this issue the other day and was transfered to level 3 tech support.
I have my settings like you where automatic brightness is turned off and is set to High..
He had a Focus with him and I showed him that when you set the theme to light instead of dark (to see the transition).. The home screen is set to bright white but anywhere that you navigate from there (i.e. the application list).. the screen dims.. making it harder to read text.. He saw what i was referring to and agreed with me on the problem. He thought it was something to do with WP7 but i told him I tested the HTC Surround and it remained bright white on any page (I know its a different kind of screen)
He put me on hold and spoke to a product specialist assigned to the Focus and said that was how the phone was designed.. He passed my concern along with hope that we may see a patch that fixes this.
On a positive note, I asked about the amount of RAM in the phone and the specialist confirmed 512MB.
I hope this answers your question.
Thanks. I hope they fix this. It is hard to read e-mail in any kind of light.
I'm glad for the dimming, personally.. the all white screen would be uncomfortable to look at on the super amoled, imho.

Thanks, I was trying find that one out.
Noticed the dimming right away as well. I read this on Anandtech's WP7 review:
Microsoft mandates three discrete display brightness settings on all phones: low, medium and high, coupled with an automatic brightness mode.

To me, it seems like Samsung tried to artificially inflate battery life by programming dimming conditions into the firmware, while still adhering to Microsoft's front-end mandate.
Tried the other two at&t WP7 phones today and they were much much brighter in email/internet explorer. Would a vanilla copy of WP7 theoretically remove this? Since the home screen doesn't dim, it leads me to believe that it's OS level.
is this only when the white theme is active? or is it when dark is applied as well?
this is pretty lame

It does it on both.
Just a heads up if you're planning on buying a Focus S (or Focus Flash), they do white-screen dimming as well.
Hi
not sure if anyone else has noticed this but it seems that the call end button, the button to view the dial pad and the button to view speaker options are burned into my screen!!! viewing in most apps it is not noticable but if you open internet explorer and go to a new page without loading a website the images of the buttons and very visiable in a brownish color I have had my focus since it was released in the US, I have also checked my wifes focus and it also has this burned into her screen.. Has anyone else noticed this?
Yes, I have the call tile, message tile, and the little circle/arrow burned into my screen. As you said, it's only visible on light colored screens, but it is visible. Unfortunately, unlike the temporary burn-in on new plasma tvs, this burn-in will not go away.
If you want to see something really bad, go up to the at&t store and check out the Focus that's on display. The Focus at my local at&t store looks horrible. I can't imagine anyone wanting to buy that phone if they saw that display model...
edit: by the way I love your weather app, I have had a few problems with it over the time i've used it, and you have always been fantastic with your support. Thanks!
Are you using blue tiles? I heard Blue OLEDs burn out faster than other colors and changed my tiles to green.
I have been using the brown almost exclusively; occasionally I'll go with blue, green, or lime, but the brown just looks the best to me.

thanks for the comment. on to your screen you have the actuall tiles burned into your screen? wow i only have the call end and function buttons burned i think its related to having my display on bright i took it off the automatic.
It's actually not the tile, it's the icon inside the tile that is burned in, but it's only visible on white screens. It's still quite annoying. As soon as the hd7s is out I'm going to compare screens, if the slcd is close to the samoled then i'm jumping ship I think...
and yeah my screen is on bright (not automatic) also. I think my problem is that I have the time out set to 5 minutes, and I never locked it myself

Based on HTC's latest track record with the Desire HD and Inspire 4G, make sure you analyze the viewing angle of the HD7-S. HTC has said it will have a Super LCD but, according to an answer they gave to a customer complaining it wasn't true S-LCD tech, the display will likely be what HTC is calling "Super" LCD...meaning it is their name for the super-sized display...and having nothing to do with true S-LCD tech.
If the viewing angle isn't as good as the iPhone 4 or Focus...or other SAMOLED/AMOLED equipped devices...then it isn't the higher-tech display but just an ordinary non-TFT LCD.
Super AMOLED is a great screen. But the pixel life span is still way short. The Blue pixels are the shortest. The old stats are 2000 to 4000 hours. New information point it around 10000 to 14000 hours. But Samsung didn't release any spec on this.
You should always keep the screen dim and keep it on as short as possible. Reportedly use a red theme will not only preserve blue pixels but also prolong battery life.
No burn in here. I have the phone set to turn off screen within 30 seconds, and have always used Lime colour tiles since it matches the Xbox Live tile.
Just a follow up on this issue, and possible a "what not to do" post. The burn in on my screen is getting worse. On a white screen, I can now see the phone icon, message icon, small circle/arrow, the word calender, and my google mail icon. I have the screen set to time out after 30 seconds, and I have the brightness set to high (not auto).
After long consideration I decided 2day finally update my (amazing) Galaxy Tab 7 to the new 7.7. I saw 5 units in hand but they all suffer from a screen issue. Even with Auto-Brightness OFF, when displaying bright images or there are large portions of white, the screen always self-dimms. I tried all possible settings, all units the same.. nothing 2do w/settings or the ambient-light sensor.. its the nature of this Tab. Ad a real-world test I tried displaying a small white square in the center of the screen w/maximum brigtness and as I enlarge the image the whole screen darkens progressively. By the time the image is in full screen (all white) brightness is less than 1/2..
Is this a hardware/ software issue? Has everyone else noticed this? Is there a fix? Its an absurd flaw.. needless to say, Im not buying the 7.7 till there is a remedy for this behaviour..

Thank you. That makes sense because its under full white that AMOLED screens use more power. Where is that setting? Im used to Gingerbread.. Honeycomb is a mess, I cant find anything I wanna get to

Its a tick box I cant recall exactly where it is but I think its like 2-3 options under screen brightness.
Though you have to take note that the white levels on the Tab7.7 are lower than compared to the 8.9, 10.1 and almost all other high-end Galaxy phones.
Last night, I went to use my night clock app with my new LG v20. On my Note 7, the screen was totally 100% black except for the numbers.
On the v20, the entire screen was stil lit - faint, but clearly still lit up in a light light grey.
Is this just how an LCD screen works, or is there something I have to do in order to get the rest of the screen to go off.
(Note, this includes the 2nd screen which was also lit - and I had the brightness at 0%).

BTW, this may need to be a separate thread - on my phone I notice that the auto-brightness tends to be too dark. Any way I can adjust it to be brighter when in auto mode, or should I just go to manual ?

Try turning off second screen and see what your results are.. Second screen has a seperate black light that slightly bleeds out to the rest of the screen. It was horrible on the V10 but much improved on the 20..

The night clock app has the option to turn off the notification, which also turns off the 2nd screen.
...oops. It did, until I followed your suggestion in the other thread about the more setting to enable time/date when in full screen or notification bar hidden. I'll have to get into the habit of turning *off* the more setting at night.
(Either way, doesn't help with the slight gray background color. I can probably just get used to it as long as I'm not damaging the screen by having it slightly on all night. I need to google if LCD screens have burn in problems I guess.)

Use comfort view on low or medium. Will help lower the ~9000K color temp some and help blacks a hair. Faint glow is typical on LCDs. Higher quality LCDs and higher quality led's can help. Lg skimped here. Sucks they didn't even give us color modes to pick from. The colors are waaay off. But using comfort view dims the blue pixels and helps considerably.

That's just how LCD works, they need CCFL or LED back light to lit up the screen, it's not possible for it to be completely black while turned on. With AMOLED the individual pixels can turn off itself which is why the black are blacker on them. OLED screens also have very high refresh rates which eliminates flickering, this is good for people who are concerned with eyes health.
Lcd doesn't get burn in, but it can get ghost image retention. It was f***ing horrible by the end of my V10 usage.. Never had the problem on the G2 3 or 4. Just the V10, even after factory resetting.

Had the same issue my V10, that is my biggest V20 concern. . My v10 was not even a year old.
I get the engineering and cost reasoning, but not sure I like the lcd screens.
