Hi guys, I have a very strange problem that has been occurring over 3 different firmwares on 2 different S2's. If i swipe my finger over the top right hand corner of the screen (like where the time, battery %, etc. is) the brightness of the screen automatically increases to either half the brightness bar or 3/4ths, or sometimes 90% of the bar.
I have tested this on 2 phones in several different apps, home screen, etc, and even in landscape mode (landscape mode shifts it to the top left of the screen which would be the top right of the UI) which leads me to believe it is a firmware problem and not a hardware problem. However considering it was an issue on my brother's phone running stock KG6, my phone running Sicopats rom based on KH3, and his phone after flashing stock KH3 then on cognition 1.5.1, i am confused as to how all of these rom's could have this issue.
Is it because the issue hasn't been addressed? am i doing something wrong? please help me out guys i know this seems like a small issue but now that i've noticed it it's bothering me quite a bit
It's a Samsung feature. Sliding your finger on the status bar while in manual brightness mode adjusts the brightness of your screen.
I thought so too at first but its so unpredictable that I dismissed that as a possibility. do you know if there are any mods which disable this?

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.
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
Hello together
I have kind of a strange problem. Yesterday I got my new tablet (IRULU X1S) and it's a pretty neat thing, runs fast and everthing was working fine.
Then I have been using the chrome browser and let the tablet lie around. When the screen was darkening (because of idle) I turned the tablet and the screen tilted. Since then there is a bright bar on top of my screen (if I hold the phone upright).
When I tilt the Phone the bright bar stays at the same place, meaning the bar is now on the side.
Its almost as thick as the status bar and it's way brighter than the rest of the screen.
One could say the rest of the screen still seems "darkened".
What is really really weird is, the bright bar is even visible if I enter the phone "root" menu (pressing vol down und power). The top pixels seem brighter than the rest.
Is this a known Android poblem? It can't be a burn in, because it happened after tilting the screen and is there since then.
I tried to remove all apps that I installed and even factory reset the tablet. The bright bar is there in every screen, on the bootscreen and also in the "root" menu. Is there maybe a way to reset the phone to all defaults, e.g. putting a new OS on the phone? Because it has to be a software bug...
Thanks for reading and I hope you have some ideas how to fix this!
So recently the bottom portion of my phones screen, about the size and place of the nav bar, has started flickering. The nav bar is disabled, I'm using pie controls, though I did test turning it back on and it did nothing. It's running CM12.1.
Can anyone help? Any idea what's causing this?
So about a quarter of the screen up there is now a flickering line, everywhere below that line now produces afterimages as what's on the screen changes.
Pretty sure it's a hardware issue, I can even see the effect during the CM startup animation.
Hi, I bought new "Cubot Note S", what I discovered in the first use was "display whitish" lines lying vertically, when set to high brightness.
At first, I thought it was hardware problem, but later I observed, actually those white(ish) lines are present when:
- screen brightness is higher than about 70%
- and when display is showing darker colors (mainly for notification bar)
- or when using camera.
And also, when moving notification bar up and down, those "whitish" lines moves sideways!
I found one solution for this problem, with the help of "MiraVision" user mode settings, by altering "Color temperature, brightness, and contrast".
You can see the problem and solution in the VIDEO.

Questions:
1) Is it really software error, or hardware problem?
2) If it is a software problem, is there any stable custom rom for "Cubot Note S" ?
Thanks!

Send the phone back to where you got it for a refund.
Many traits with the cubot note s include -
Doesn't boot up and hangs.
Boots up and the sim icon is missing.
Screen burn.
Boots up and sdcard missing.
Problems connecting to wifi.
The ota updater is dangerous and should never be used.
It has a couple of malware apps in system.
Volume button not working as it should.
There are also lots of pro's of course so it is worth £50, but only £50, no more than this.
