[Q] going negative why should it be bad? - Android Q&A, Help & Troubleshooting

I've looked everywhere i can think of for an app that will turn adobe reader or the the phone's screen in general negative to reduce battery usage while reading. any suggestions?

I use Moon+ Reader.
It lets you slide your finger down the left side of the screen to increase/reduce brightness.. and when you toggle Night Mode (black bg) and slide down past 0% it turns negative. Or what I call night vision...

Please use the Q&A Forum for questions Thanks
Moving to Q&A

yes i tried that program but it won't let me open pdf's
I Have a kobo as well as the Kobo app but it's useless for PDF reading as well.
PS my apologies to the forums i had to stop watching the disclaimer video halfway through to change a diaper and didn't bother finishing it till today.

Depends on your phone. If it is not rooted than probably no. If it is, lots of roms have screen filters in them (cyanogenmod being the main) .
If your phone has any kind of screen other than OLED, the only thing that saves battery is reducing brightness. LCD screens use the same amount of power to render black as they do white.
OLED screens use only 20% of the power rendering pure black as they do rendering pure white.

Superdim root required

Check out superdim (root), its in the market for free, it works amazingly well. I always noticed the atrix was particularly bright even at its lowest setting. I never *****ed because I was just happy to have a bright screen visible in daylight. Now we have best of both worlds.

Sweet! thanks
AdjBrightness works well too.
Nice, I will have to check these out. The blindingly bright "dim" setting was one of my pet peeves with the Atrix!
I have check it now, and it works like a charm, very low bright. excellent.

Thanks! I was actually just noticing that super dim didn't stay dark. What a great idea
Edit: I noticed that super dim actually darkens the screen while this new deal simply puts a dark patch over the screen. That's the difference between root and no root lol
Ps use both for super reading mode!

I've been using Elixir which does all sorts of stuff but one of the options is a tggle widget that lets you shuffle through up to 5 brightness settings. I use Auto, 5%, 12%, 40%, and 60%.

Well after playing with screen filter, I'm not crazy about it after all. It does nothing to the backlight but puts a grey tint to everything which makes it hard to read at the lower levels.
However, I've been emailing the author of superdim. He's already put out a version with the home screen profile shortcuts I asked for.. wish more devs were that responsive!

If you talk to him again tell him his app rocks and he's got the atrix communities thumbs up.
Side note I somehow got the dimness to stick through a screen off. Start at boot would be nice tho..

I actually just found him here. [APP] Superdim
It seems like the brightness after wake sticks as long as it's at 20 or above. It's like 20 equates to 0% in phone settings.
It's funny, most noticeable at 0. Hit the power button to shut the display off, and you notice it gets brighter before turning off.
Just tested this on my MT3GS, I can set it at 0 and it stays there. Even after a reboot.
[EDIT]
Working with the dev some more, I think he's got this fixed in the next beta! It restores the dim settings after wake! Stay tuned!
Seems to be fixed... my phones lowest is 30... very weird

automatic brightness bug

Hello,
theres a bug in automatic brightness: if you turn it on and hold it against the sun the brightness will go to maximum but it won't get back (darker).

I can't help myself, 3 thanks virgins in 2 days!!!! Owned!!!! last time I held something up to the sun it melted. Its kinda hot!!!!........
Ok in all seriousness I have not had this issue....did you try rebooting your prime? I have noticed some hicups from time to time, like touch tones stop working....but if I reboot it will work again. I am sure its just the newness of ICS, these things will get ironed out in time.
I leave it off anyways. Its a known automatic brightness is a battery drainer. You'll get better battery life with it off.

I think this is more of a feature than a bug, although I keep mine at one certain level anyway.
It's to give you a more seamless experience, as soon as the screen goes off and back on it adjusts. It's so when you're reading an article and move from one area to another, you don't get a surprise mid-sentence. I always hated reading things off my phone with auto brightness on, couldn't just focus on the words had to keep tripping up on a constantly changing screen.
With sun i meant that you can hold it against a bright light
Sry for my bad english...
I've actually noticed some differences in the sensitivity of the light sensor on various units. Some do seem to get "stuck," where others maintain an accurate measurement of ambient light. This seems to be correlated to newer units (e.g., C1 units).
The one I'm using right now does switch lighting both more quickly and, it would seem, more accurately. The ones I had previously would get stuck either on high or low brightness (with very little adjustment in between), and I needed to toggle the auto brightness button to get them to adjust to new conditions.
I found auto brightness on the device to be an annoying burden if anything. I just keep it pretty low all the time. Better that way anyways.
Same problem here - The brightness goes up under bright light, and won't readjust until the next screen off/on or reboot.
Does anyone have a Prime that adjusts back down without turning the screen off?
I swear it's intentional and not a bug, although they should offer you the option of controlling its parameters. Just have to wait for the unlocker and some custom ROMage.
But seriously, I think it's to keep a continuity in your current session, so that if you're gaming or working (the two things this tablet's for) you're not plagued by an ever-changing screen that distracts you...

I can see how the concept of continuity can be good. But in my case for example, switching the bedroom light on - followed by a certain increase of brightness on ATP - then switch the bedroom light off to go to bed - the persistent brightness (tested for >15mins) can be a little straining on the eyes. Although readjusting the brightness is as simple as 'clicking' the 'auto' icon on/off again so that the brightness comes down to appropriate level (it only takes 2seconds to do it) - I think this is defeating the purpose of having the auto-brightness setting in the first place.

Oh I whole-heartedly agree. Going from my living room anywhere else in the house causes blindness with auto brightness on. And it acts completely opposite on this device than all others I've touched that use the feature. And like you say, if it's "automatic brightness" then why would it not be totally automated?
I'm just saying there's definite reasoning and programming behind it, it's not just some bug per se.
Therefore, don't expect ASUS to do anything about it, it'll all be up to our wonderful dev's here; they'll say it's properly functioning even though it's bass ackwards from everything else in existence.

Screen burn in

So on my gnexus i always loved having the screen brightness cranked all the way up to show the beauty of the display but sadly i soon realized the horrible burn in that came with it a few months later. My question is how likely is a screen burn in to occur on the gs3 if i have the brightness all the way up? Also as a side question how drastically does full brightness drain the battery as well?
Yes and Yes
If you even bothered to search the forums, you would have seen that I already posted a Screen Burn In post that would have answered your question instead of opening up another needless post.

WTF??? Screen burn in??

I was trying out a compass app on my LGV10. The app has white lettering, etc and a black back ground. The phone needed to be charged so I just plugged it in and set it down. I didn't pick it up again till the morning. I killed the app and then noticed very lightly I could still see the image. You you can see a very,very faint image of the compass app. I tried turning it off for a couple hrs but it is still there.
I"ve never heard of LCD screen burn in; but there it is.
Anyone dealt with this before??

yes, with time the screen get "ghost images" but they dissapear if you turn off the screen for 5/10 minuts. Mine is getting that kind of "ghost images" from apps i opened and mine is on the sides they get a yellowish tint in both sides and some in the top of screen, nothing to be scared of...isnt burn in...but overheating of the screen.
Use BLUE LIGHT FILTER app (on play store has icon with a phone with blue screen) and set "filter opacity 15%" and "screen dimmer 50%" on color BLACK. I read that in 3d v10 of my model (h962) and ghost images never happen again with min o max brightness in every use.

Reply; thanks for the info guys.
Day 2 and I cannot see the latent image from the compass app anymore.
Not exploring the woods or anything, but I need to install a TV antenna on the house and have to aim it dead on 115* from true north.
That you cannot truly ascertain without a compass. From standing in my yard, what seemed like true north to me was actually NNE.

Wow that worked. Thank you. The trick seems to be to use black color. Been trying with red filters but did not work. I only need to set black filter to 5% only and all ghosting is gone. This keeps brightness high. I had some pretty horrible yellow permanent ghosting on edges of screen that appeared very fast. Now not at all.

I will have to try this. I cracked my screen on my V10 and picked up a bootloop one on eBay that still had a perfect screen. Did the swap of my motherboard to the new screen housing. All went fine except I noticed excessive ghosting on the bootlooped display.

Please report back if it works for you too.
I used this app: https://play.google.com/store/apps/details?id=jp.ne.hardyinfinity.bluelightfilter.free
All my screen needs is a black filter set to 3% (might even less, have not tried lower) opacity and I never see the heavy yellow ghosting that came after minutes on edges and top of screen before in the same places. As a result my whole display is now cooler and cleaner most of the time because the ghosting was pretty severe when the phone was used for a while.

Avoiding screen burn-in while Tab-S6 sleeps

I notice when the screen on the Tab S6 sleeps, text notification of the battery charge level will persist on the screen. This only happens if the USB power adapter is connected to the tablet and "screen saver" is disabled. The text remains fixed at a consist location (bottom center) of the screen, and remains for the whole time the device is sleeping.
My concern is that this text will eventually cause SCREEN BURN-IN.
MY PROBLEM ...
Display off, with wall adapter powering ON
. Screen is blank except for battery charge state is permanently displayed
. Bottom of screen shows "100% / Fully charged"
. My fear is this will eventually cause SCREEN BURN-IN of the displayed text.
MY SOLUTION ...
Make a black JPG file, which is used for screen saver, during sleep.
. Place a JPG file in folder: \DCIM\ScnSaver
. JPG file should be sized as 2560x1600, with pure black content.
Display > Screensaver > ON/OFF
. Photo frame ON.
. Select photo frame from folder "ScnSaver"
APP FOR SLEEPING
. Optionally, Install from App Store, "Screen Off Trial", by Iwashi Soft.
. This app will sleep the device and activate screen saver.
. Many other "screen/power off" apps will not activate the screen saver.
Yes. Same issue with the Note 10/+.
No need to worry. Assuming Samsung is still doing the same thing, it will occasionally move the text around.

I watched the charging notification on my N10+ and it does not move. At all.
And even if it just moves a pixel or two in any direction,nitnwikl still burn in over that area.

It will not burn in that area. It does move the pixel around, it's the same for Note 10 series. I'm sure Samsung should by now already know how to combat screen burn in.

Even if it moves a little (it doesn't), it doesn't move the whole charge icon. Just a couple pixels to the side leave about 90% of the pixels in the same place, so Ilit will eventually burn in.
By the way, I'm holding a N10+ in my hands right now, and the charge notification does NOT move.
I found this issue last night as well. I share your concern. I'm likely going to be powering the tablet down for overnight charging till this is addressed more completely.
I really don't understand this. I have changed of course. All time screen off. When wake it up, it said fully charged...
Then it must be a question of a setting. I'll go looking for it tonight.

If it's like the Note 10, there's no setting to turn it off. But there is a work around.
Go to Display settings and turn on screensaver. Set it to "Photo," but don't hit the settings icon next to it or point it toward your Google Photos. That way, it won't have a pic to load for the screensaver and will instead load a black screen.
When you plug it in, it will time out to the screen saver, which will be a black screen WITHOUT the charge notification.
If it doesn't time out to screensaver, just wake the screen up then let it time out on its own.

Thanks for the information, but if I understood the previous poster, this issue is not happening on their tablet. Tells me it may be a settings thing.
