Screen Dimming Obervation - XPERIA X10 Q&A, Help & Troubleshooting

Have just changed over to Global Generic 2.1 having tried both Nordic and UK Generic and have noticed something i didn't notice on the others.
If using an app such as Handcent or K-9 mail if I put my hand over the proximity sensor the screen dims slightly.
Not a big deal really but just curious as this didn't seem to happen on the other firmwares.
Anyone else on this or other firmwares notice this???

Whyl reading ...sms or jst ..leaving the screen open
it dimss sumtyms ..it luks lyk there is problem in the screen
its nt a bug
set yewr brightness to highest level nd lev the phone on home screen
nd w8 before the phone gets lock itself
before the phone gets lock. its screen autoadjust the lowest possible brightness it is a signal that the screen is gng to turn off
nd if yew always use ur selfphone in low brightness ul fink that there is sum problem in firmware or yewr cell screen
chillout there isnt any problemm

Have you tried to close the ambient sensor with your hand? If you're on dark room it should automatically lid. but if you're on the bright room, it is of course turned off. there's an app on Market to monitor the ambient sensor. Play with your thumb above the sensor to see if it's working or not.

however my keyboard light dont lid while using it or opening it as usual any help please
well, maybe reflash? dunno for another solution.. if it still persist, maybe you need to reflash with SEUS.. if it still like that, maybe you can ask to Sony Center i guess..

actually my fone fall into the water 1 week ago..than i opened it & than close it after removing water etc.. from whole fone after that its working fine no problem at all..
but keypad lyts not working from last 2 days i think (but lights gets lid when we unlocked the fone either by sliding up the keyboard or by lock key but only for 2-3 secs than go off automatically even in dark)
so i want to know is it hardware problem?? that does not seems to be
or any software problem..
i update via seus 2-3 times but no works
is any other way to light it up the keyboards while we open it & ambient light sensor is also working
i cant find wat to do.. & due to water damage i think warranty also void..
no 1 to help frnds?
is there no 1 to help friends?
my keypad lights are working all are lid but only for few seconds may called it for 2 seconds that also when we unlock the phone either by slideout the keyboard or by pressing the unlock button...
i flash my fone 2-3 tyms by seus but no sollution...
is there any solution via changing drivers etc to enable keyboard lights only when we slideit out without the use of sensor or else..however my sensor is working
or any 1 please provide me there folder files of "sys/devices/platform/msm_pmic_misc_led.0/"
Hmm i don't know any other solution manjeet. But i want to share you the same experience like yours..
I have just reflashed into the normal firmware. but when i tried to test the light by closing the light sensor, i am surprised to know that the keyboard was not lid too! It just works for 1 second when i open the keyboard, and turns off soon. i was in panic then, but i tried to be calm, and when i tried to hide into a dark room, it works again. Fiuhh..
I don't know but maybe you need to really go to the dark places. Seems that the Proximity sensor and Light sensors work in tandem. If it still fails in the dark, then i guess you really need to have it serviced.. Dunno bout the cost, but it shouldn't be too expensive..
Good luck with your u20i bro.
thanx hansip......

[Q] HTC Amaze Screen Goes Black After Ending Phone Call

I have Speed Rom 5.1 on my Amaze. When I am finished with a call, the screen stays black. I try to hit the power button, but nothing happens. I have to remove my battery in order to reboot. Can someone shed some light on why this happening? I am thinking that it may have something to do with my CPU Tuner settings, but I am not sure.

Probably that or a bad flash, just reflash, see if it solves the issue.
Most likely it's something simple, like an issue with your proximity sensor. I know there was an app that could calibrate that but I forgot what the app was.
Stock Rom - Black screen while phoning
There is a similar problem on my wife's phone with a stock rom (not rooted Amaze from T-Mobile). When making or accepting a call, the screen will instantly go off even without leaning the phone against anything and won't turn on unless the power button is pressed. Sometimes the screen would turn on by itself after a while after the other phone was hanged.
I've downloaded AndroSensor app: the proximity value does't change even when touching the area near the earpiece. It keeps showing ( 0.5mA ) 3.5 in.
I've found a thread which is there since april 2012 and describes quite a similar problem.
okay.. i just the original post date for this thread.. please don't bring back threads that are 6 month's old which issues might have been solved already since no ones been posting in it for 6 months...
(anyways) this is what i was gonna say
on my current s3 when my phone is placed to my ear it cuts off the display.. and if you pass your hand anywhere near the sensor's to the top near the camera it cuts off the display.. maybe there's a feature like that enabled on the stock rom also.. or you could possible check with the system settings to see "screen" on/off settings in display or power saving mode.. or something...
Thanks for the answer. I didn't notice that the thread was that old. I think I will keep up a newer one. But the current issue isn't likely to have been solved.
The problem doesn't seem to be triggered by wrong sensor measures (because the screen will go off even after disabling the sensor) nor does it depend on the rom version (same thing on the CM10).
Resolved:
It will sound stupid but I have found a simple solution:
I have just wiped the screen in the upper left corner where the proximity sensor is located and it started behaving normally. Though I don't use any protection tape on the screen it seem to have become less sensitive because of mud or sweat.

Is this Android, App or Hardware

Hi Everyone,
So I noticed not to long back that my phone has been changing brightness without the brightness bar moving. For instance I unlocked my phone moments ago and my screen was very bright. I went into my brightness settings and looked at the bar was set at 60%. As soon as I touch the brightness bar the screen dims back down to where it's supposed to be.
Now I am thinking this is purely a software issue but I am still a little worried. I have a Galaxy S3 Optus AU. It is running the LF2 firmware and is not rooted or modified. I have turned off auto brightness and power saving for the screen and this problem still persists.
Has anyone else suffered any such issues with there device?

sry my fault...read to quick
hmm the only thinng i can imagine on the go is...has been your battery been on a very low amount of percentage
because i think the power saving mode is changing the brightnes on its own
No the battery was at 90% when it happened last. I have factory reset the device to see if it fixes the issue.
OK the issue is still happening. Altho I have now noticed that it happens when unlocking the phone. If I re lock the phone and then unlock it. It's back to normal.
Well...even stock firmware is not protected to crash or do sth it shouldnt do by the way
so think about a clean install of the rom or a software update this might fix your problem

i updated mobile phone to android versiopn 4.1.2. this morning. Unfortunately the problem still appears.
Maybe its a hardware defect?
Try to disable somehow light sensor and change settings to non auto brightness.

i disabled auto brightness and set the brightness to the highest level. But its still same: very dim and after a while a black screen; after a few times of unlocking, the display works normally
I have just seen the same issue on a friend's S3.
Anyone else? I feel like this is a very big issue that is still lurking in a lot of devices.
I tried it myself and I toggled the power button to turn the screen on and off.
It doesn't take long but sometimes when the screen turns back on, it's super dim and you can faintly see the lockscreen image.
You have to cycle the screen several more times to get it to the 'correct' brightness, and no it is NOT a brightness setting.
It's some hardware issue in the phone.
Sorry for the necrobump, but I only found this thread. I have this problem too since about a week back. It makes my phone useless at times. I first thought it was a software issue. I have an app (called Twilight) for dimming the screen more than normal settings and also toning it, for nightime use, and I thought that was the culprit first, but nope. I have flashed rom, recovery, wiped all caches I can think of. Still happens, just now I was in the middle of installing android revolution hd, and the screen ultradimmed on me so I can't finish the process
Thing is, a few months ago I managed to crack my screen by way of gravity and concrete. I let the samsung brand service centre in Stockholm repair it for me (it is out of warranty) and this issue with the dimming never happened before that. Then again, it didn't happen directly afterwards either... but still. So, I am thinking: either me dropping it caused more damages and this is because of that. Or the service center did a bad install of the new screen. Or, the replacement screen that was installed has a defect in itself. I am leaning a bit towards the third explanation... maybe different batches of screens?
Does anyone have any ideas? If I am to contact the service center and complain about their work I would like to be able to point towards a "known problem"...

Take it back, if it didn't happen before then the new screen is most likely.
It isn't a common problem

I9300 ads turning the screen black

I recently updated my i9300 to paranoid android to 3.97 and I'm having two issues... First one is that apps that have border ads down the bottom.. Facebook.. Cheeseburger.. Astromanager etc if you take your finger Off the screen the screen turns black with only the ad showing..... The other issue is that the screen brightness can't decide if it's full of low. You press the power button the lock screen comes on Instantly dims.. Doesn't matter if light Meter is covered or light shining on it.. Disabled all power options.. Auto brightness is off... Tried lux app set all to 100% still dims.. When you run it after the screen dims it shows still being 100% touch the maximum and it comes back again.... Anyone have ideas. Googled ads but came up with nothing for black screen issue... Tried other solutions for the brightness issue still no luck.

Go to PA Q&A thread next time: http://forum.xda-developers.com/showthread.php?t=1887819
Due to lack of graphic driver on 4.3, the black screen thing could appear. There are two+ solutions:
1. follow this step by dontwannabehere

The fix is the following:
On your build prop file
There should be a line that says something like this " hwui.render dirty regions = false "
Just add the word debug at the beginning of the line "debug.hwui. render..... "

for your first problem: the glitches should have been solved with newest cm sources. But look in your build.prop if you have the entry "hwui.render_dirty_regions=false" if yes then change it to "debug.hwui.render_dirty_regions=false" without the " " )
for the second problem I cannot help you, as I am not using paranoid. Look if there is an update or ask in the paranoid Q&A thread http://forum.xda-developers.com/showthread.php?t=1887819 (you could also have asked there your questions )
EDIT: sorry. I am ALWAYS to slow in writing aaargh
Appreciate the quick response... I tried the build.prop editing and this is where it got interesting... I cant edit it ... I've tweaked in the past with ES file explorer or root explorer but on this occasion the apps wont allow it ...does not allow the changes to be saved.... checked the root and thats fine, busybox is installed and working fine... my workaround was to tweak build.prop of the 3.97 rom of PA and apply it it from recovery.... this seems to have fixed the black screen in apps... so thanks for that.
I also just grabbed the 3.99 nightly of PA and build.prop already has the change applied, applying now.... result seems the brightness quirk is still there ... I tried the android sensor app and the lux settings seem to be correct so the light sensor is performing as expected the brightness is just not doing what its told... even if I set it to automatice brightness change the sensitivity and apply 100% to all different lux settings it just ignores it and dims the screen regardless... !!
