c6833 black screen and how can I fix it? - Sony Xperia Z Ultra

Hi, I have experienced black screen as soon as I call someone. I read the forum and someone posted to do proximity switch test and I followed, only to know that the proximity switch is always on. How can I fix it?
I am considering to downgrade from stock 5.1.1 to earlier firmware to do proximity caliburation. It is doable?
Thanks.

[Q] Galaxy S2 infrared led error?

Hey
I have this simple question about this weird infrared led next to my front face camera that is showing when im talking in the phone.
The people im talking to, says that i have a bad signal/voice in the microphone
Im running the nordic NEE ki8 firmware android 2.3.5.
The error is just like the one in this video, except mine is only showing when im talking with other people. look closely at this error in 0:10 in this video
http://www.youtube.com/watch?v=8MI7ftudEEo&feature=related

I dont know if this is supposed to be a feature or even an error at all.

It's the promimity sensor. I have no idea why it's flickering away on that video though.
Thats a proximity sensor

Okay do you know how to make it stop.
I dont think its normal.
its annoying that it is flickering when talking to people.

Double posting and large, unnecessary signatures are annoying too .
Oinkylicious, frankly, i don't give a damn.. Save the criticism for someone who cares.
I think you are here to help instead of criticising, aren't you?
Ontopic; i don't know a way to make the flickering stop. Also, om my phone, the flashes are very very dull. You almost don't see it as in the vid where it is extremely bright (compared to mine)...

Well maybe other sgsII users arent aware of it yet
dont know if it depends on which country/carrier the phone is bought.
Mine is originally a 3 mobile branded.
In anyway we are screwed, unless samsung support can help.
thanks for your positive response :-D
i have tried flashing originally 3 mobile branded firmware xwke1 and upgraded to 3 mobile xwki8 branded firmware via kies, but that didnt solve the problem.

funny because most people on xda have a signature as large the way you describe it.
I have found out that this is a light sensor according to the manual
its placed like this: frontface camera - proximity sensor - light sensor.
I remember that i turned off the automatic light in the screen settings and then manually adjusting the light. i turned the automatic light on again.
dont know if this is related.
If it is an infrared signal, can it be used to control the TV?
Have you tried switching off proximity during calls (Check box in settings > Call )? Will leave the screen on but might solve your blinking sensor problem...

Lumia 920 Blinking Screen (no one can fix it ?)

Dear All:
I just got a new Yellow Lumia 920 and I upgrade it directly to Amber GDR2 as I got it through Wifi.
My Lumia 920 Info:
1-Manufacturer name: RM-821_apac_Malaysia_316
2-Mobile operator: 000-MY
3-Carrier: CV Malaysia
4-OS version: 8.0.10328.78
5-Firmware version number: 3047.0000.1326.2009
My problem is when I press lock key to unlock the screen (specially under fluorescent light) the screen will start to shake and blink for some time.
My setting is Auto Brightness off , Glance off, magnifier off & brightness set to low.
I believe that the issue is about ambient light sensor
I tried soft reset and turn off then turn on the mobile in dark room , cleaned the mobile in spite of it is new.....nothing work.
so is some one know how to fix this issue & Is it a software or Hardware issue ?
Note: I live in Middle east and there is no warranty for my mobile
By the way
I installed more than one screen pixel test and after i run the test the screen was blinking much more than before and now it is back to it's normal faulty manner

Maybe a data factory reset will help you. If it doesn`t reflash the firmware with Nokia Software Updater for Retail from here http://jkorondy.com/Lumia920, also is a tutorial for how to do it. If that doesn`t help also it may be a hardware issue bro. Good luck.
I tried soft reset then hard reset but still
turn off then on in a very dark room and it is still the same
I notice when using black image as lock screen it will not shack or blink .....................!!!!!
some Nokia 920 owners said it is a normal problem ????!!!!
why Nokia & Microsoft doesn't pay attention for small things ??????????
Ok I just contact windows phone 8 support & they told me that the problem can be fixed If I flashed the firmware correctly in Nokia support !!!!
Hi Guys .
I'd like to confirm that I already flashed my Lumia 920 with latest Firmware available for my device {Downloaded through Navifirm}, but that didn't solved the issue as the Microsoft team promised.
I believe now that the issue in the Hardware Side now
Not sure But still I hope that soon some one will figure out what is this issue and blinking screen is about, Hope soon
Nokia .................... I will think twice before I will buy anything from your produces in Future.
So what happens if you put your finger over the light sensor and keep it there for a moment? Does it get worse, better, or stop?
If it is hardware related, then this is what a warranty is for. Send it in.. If you don't have a warranty or can't send it in then the best you can do is take it apart and maybe clean the sensor and around it and that might help or fix it. Otherwise you are out of luck.
If somebody had a fix for you they would have posted as this is a popular forum. Seems you are the only so far that has posted such a problem. So you are the first and it is up to you to tell other how to fix it if they encounter the issue.
Man I gave up
that's it . there is nooooooooooooooooo fix, there was many threads in different forums and no one could find a fix.
screen replaced , firmware flashed ................... what else
it is sound something even Nokia can't solve it

Got same problem. I sent my phone in warranty and they recalibrated my screen
Are you using screen protector? Try remove it and then do a reset. It fixed my problem. The screen protector that covers part of the sensor making the screen flickering.
Anyone know how to fix that issue..i have the same issue on my Lumia 920..please give me some solution for that...

I don't understand the question, maybe you didn't get what I said ?
There is no proximity sensor, instead they use some gimmick, like accelerometer + AI or else to simulate a sensor effect, which is crappy if you don't use the phone in the planned position/situation...screen going black mainly if you use phone while lying down according to my own experience.

Thank you for your reply Shokmah.
I actually understood exactly what you meant. I thank you for that valuable info.
I was wondering if there was an app in Google App Store which would actually prevent my screen going black while I am on the phone.

Question RMX2202_11_C.17 problem with proximity sensor

Hi,
there are two problems after updating to C.17. The proximity sensor began to work in reverse. During the conversation, before I put the phone to my ear, the screen turns off, and when I put my finger in the place of the sensor, it turns on. Another problem is AOD, it worked without a problem before, now only works for 3-4 seconds after the update. Do you know what's going on? Factory settings were made. Please help.
Is it the Chinese version?
I also did an update C.17 China. My vibration of my phone started giving problems.

EU
Man I'm sorry to hear android 12 has given me so many issues that I had to revert to android 11. Also on EU version. It's really sad how terrible and buggy the updates have been from Realme. Not impressed.
