Sony Xperia T on Bell Screen flickering. - Sony Xperia T, TL, TX, V

Now I'm on the latest stock software 4.1.2 but I'm rooted. All I did was install titanium backup.....anyways
The screens color flickers when in androids gradient screen. You know the splash screen when an app loads? The blue grey gradient? Flickers like mad. Also, I feel like the Bravia engine is always on and affecting the ui. Brightness will change by itself and so will the color sometimes. This didn't happen when I played a game!!! Software issue? I also loaded up gradient images in Google no issue there.
It's annoying, whenever a grey android menu pops up sometimes the brightness and color will dim then go back up again when I exit the prompt or menu. Help??

Ugh like right now, the loading circle spun when I posted this topic. When it disappeared my screen brightened up.

Prompts or menu things like this dim my brightness and color. Then when I exit it the brightness shoots right back up and color as well.

Is the brightness set to auto? Try setting manual brightness.
Edit : bootloader unlocked?

Brava engine and auto brightness turned off, brightness set to max
Fir example you press the power button and the menu opens right? You don't shut off and exit the menu. The brightness seems to have dimmed but goes back up again. This happened whenever grey menu pops up I think. Or when I pull down the notification center and exit it, the brightness seems to have dimmed.as well but goes back up again after.
How can I check fir bootloader unlock?

I'm sorry that I don't know what's exactly happening on your phone right now.
You could try resetting your phone to default settings and see if the problem still persists.
And forget about the bootloader part.

Ah it's okay, I've tried that. It seems like an overly aggressive Bravia Engine/auto brightness, except it doesn't apply to just photos and videos but the system as well.

on my xperia t it looks like the background ui elements get dimmed while foreground elements, like popups are still bright. This looks like a compositing effects with a nice dim transition and this looks pretty normal to me.

Why is my xperia t u able to render gradient images properly?
I mean the screen shots are low quality but clearly you can see that the edges of the glow look bad.

Dim screen further.

I find that my screen doesn't dim enough when I'm in a dark room. I've obviously taken manual control over brightness. I k ow its possible for the screen to to dimmer because my alarm application can dim the screen. But is like a way for this to be system wide. Does anybody know a way of doing this?
If you can share I'd be most appreciative.

I use something called screen filter from the market. It puts something similar to a black screen overlay on the screen and allows you to control how much it dims.

You can also get an app called Curvefish Brightness Level which will dim your screen lower. The phone controls only allow you to bring it down to 8%, I believe. This app lowers the brightness to 0%, which makes a difference.
For further dimming, use the app recommended above.
My eyes thank you both. I tried Curvefish's solution and it couldn't do low enough (works well, but my room is pitch black at night. Would work for someone in a theater which is why I'm keeping it). Screen filter works extremely well for my needs. The only downside is it does some funky things to blacks when enabled. I can live with that, and its a small price to pay for might time reading comfort.
Thanks again.
EDIT And if anyone wants to know, I'm using Alarm Clock Plus. I like it a lot.

Screen keeps on getting Auto-Dim

Every now and then, my screen brightness keeps on lowering automatically. Sometimes, brightness gets reduced to half, sumtimes even lower!
All the settings under power saving is turned off + under display -> Auto adjust screen power is also unchecked…
Anybody knows wht can be this issue ???
I believed you could try disable this option too. As it also dim your screen according to the image or program showed on screen.
Hope this help.

Hi again, I just found another thing to make the screen dim after I set screen to low light.
When I set light to low. Any program I used will not effect to screen light except the build-in browser. When I open the browser my screen dim itself to high brightness.
As I recalled, build-in browser have function to dim the screen too. Maybe other programs may have this function and can effect screen dim.
Hope this may help.

I also have this problem of ramdom screen dimming.
Auto brightness unchecked. The same thing with unchecking auto config screen.
May be it's a conflict with the inner brightness of the default browser.

color too bright

For same software,iphone display words as dark red,but note is bright red. My eye is very tired. How to adjust it?
Go to settings....display....brightness -and then adjust brightness. Alternatively, swipe your finger from left to right on the notification bar on top of screen to lessen brightness. You can also change screen mode (settings...display...screen mode) which can make colours less bright.
If you try and all these options fail, try some ray bans. They work for me ;-)

Also try changing the display mode to movie since the others are very oversaturated.

I advise you to use the free widget Screen Filter.
With this widget you can set your screen to every brightness you wish.

Warning for those who use "screen filter"

It's a great app that dims the screen and make it easier for the eyes, but I found one major bug today. While the filter is on, you wouldn't be able to install any apk's. The button is there, but you can't click it, you can only cancel. Basically it feels like your touchscreen has a dead spot right on the button.
Anyways I was panicking thinking my nexus 7 went crazy, and I uninstalled a lot of apps just to find the culprit. So this is just hoping no one else panic like I did. I also already emailed the developer.
1. It was discussed before, use search.
2. Stop using that crappy app and use https://play.google.com/store/apps/details?id=mobi.omegacentauri.ScreenDim.Full for reading.

Um, I use that app, but it doesn't dim it lower than the system does. I just use it to quickly adjust the brightness instead of going into the settings.
EDIT: Yeah, I'm an idiot. That's not the same app I use. Just looks very, very similar. None the less, I tried the free version and it did not get noticeably dimmer.
I'm using the app '2x battery' which also has a screen filter feature, no problems in use, also seeing as I paid up for it it allows to filter by colours, so have set it to fade in a purply filter which basically reduces the green tinge my screen has, took some fiddling to get nice result but got double whammy of screen a little dimmer for indoor use and better colour balance, no lag or Faff so far.
Free version just allows a standard dimmer fine for most scenarios

Well I think screen filter is simple and it e works very well. I'm going to continue to use it, just have to turn it off if I'm installing apk's
I use 'Night Mode'

I am using screen filter with Sony bravia engine and it all works great. screen filter still gets blurry at lower dimness though.
Try Root dim or Voodoo display filter. Both are great for the purpose.

This thread I'm only taking about the specific app named "screen filter" though, just so people won't get confused. It works great btw, the screen can get as dim as you want.

The app you want to use is Custom Auto Brightness by Dmitry Matuzko. It lets you set brightness levels based on your light sensor and has the option to use screen brightnesses lower than the programmed limit without using overlays. Obviously you won't be able to go lower than the hardwares limit, but in most cases the manufacturer sets the software limit much higher than the hardware limit.
Onibabar UpdateUpdate
Thanks for posting this thread! I don't even use a "screen filtering" app BUT I was having the same issue were my INSTALL BUTTON was no longer working, and because of this thread I now knew at what sort of 3rd party apps to start looking at. At first I thought it was the ROM I was on, then I thought it was only on 4.2.2 ROMs since it happened on more then one of my setups, and finally, I thought it was a Mod I always use, that gives my phone inverted apps. In the end though, it turned out to be the latest update to the Onibabar app from the Play Store. Its a app that places a battery bar on your screen and the latest update allows it to be positioned going down on either the right or left side of the screen, in addition to the top or bottom. So whenever its set to go on the left or right side, it disables the INSTALL BUTTON when attempting to install an app from a file explorer...

Does anyone have a solution. .

I have used many jb roms but still have an issue when I go to browser the screen dulls away down..is there anyway to sort this in a setting that i've overlooked or is it a feature or bug in j.b itself..?

Open the browser and click the menu touch button and go to brightness. now disable the auto brightness option.

Thanks for reply but why do I need to disable auto brightness I never had to in gingerbread or ICS...its not a big issue just wondering why it does this..
Sent from my Xoom using xda premium
In ICS as well browser and video player has its on brightness settings.. So disable individual auto brightness to make it dim and light up as the other screens
My stock ics has its own video and browser brightness and its auto brightness. So even when i am on auto disabled mode like in the dark room. Its sometimes annoying.

Cheers for the replies guys I got it sorted..its a power saving setting I had to untick to stop the dimming its a setting that must have been added..)
