Nokia N9 light sensor stopped working
 

Nokia N9 light sensor on the top right corner has suddenly stopped working. Yesterday the phone fell on the the floor (screen downwards). I noticed that the screen from that side came out a little bit. When i push it, it gets inside. Basically the screen is not perfectly fitted. I did a soft reset which didnt worked. Then i did a hard reset which ( i dunno how ) completely removed the meego os, however i could boot to android through dual boot nitdroid. I then somehow managed to flash the dead n9 through phoenix.
the phone came to life but the problem persists..
the two problems that incurred were,

1. Double tap to unlock screen is now completely workless and i am compelled to use the unlock button

2. When i make a call , the screen becomes totally black , the other party picks the calls and i cant end it, even the unlock button doesnt works, the screen becomes completely black just as it was on my ear and the sensor was activated. The light comes when the other party ends the call. This is bugging me the most.
please helpppppp.



p.s . Just as u, i also believe it is a hardware issue and i cant take to nokia care bcoz it doesnot have warranty and they do not take phones wdout warranty here.

i would like to advice all n9 owners to take full care of the device bcoz it is fragile compared to other nokia smartphones. And yes, the nokia black cover was on when it fell.

the phone fell from knee height.

Sorry about the issue, but two suggestions for your problem.
To check if it is indeed a hardware problem, use a digital camera's viewfinder (another phone would do) and point it at the proximity sensor, you should see it blinking if it's working.

To disable the proximity sensor, edit /etc/mce/mce.ini as root, remove "proximity;" from the Modules= line, then restart mce (or reboot)

Re: Nokia N9 light sensor stopped working
 

Thank you very much bro. I thought it was the end.
your suggestions are highly apprexiated and i will get back to you as soon as i try both the methods.
thank you for the quick reply.
:)

i used a camera to check if it was working or not. I couldnt see something blinking..

hey i found the solution

WARNING : BACKUP YOUR DEVICE BEFORE DOING THIS

download you firmware files through navifirm
both the oem( almost 1gb ) and emmc ( almost 2gb )
Change oem file name to " main.bin "
Change emmc long file name to " emmc.bin "

flash with this command:

flasher -f -F main.bin --erase-user-data=secure
flasher -f -F main.bin -F emmc.bin --flash-only=mmc

problem solved :)))

My phone was sent to Nokia Care and after I claim it back, I have this issue!
I will try to flsh emmc now, thanks for the tip!

Re: Nokia N9 light sensor stopped working
 

For those you have this issue, is hacky brightness installed on your device (notably coming from N9Quicktweak)?

Re: Nokia N9 light sensor stopped working
 

Nope, its a clean device now..
Anyway how long will secure feature erase takes? What will happen if I plug it out halfway?

Re: Nokia N9 light sensor stopped working
 

OMG. im having the SAME problem! i dropped the phone and now it goes to blackout when i make a call. what is the problem? please help me fix it!

FIXED: Nokia N9 light sensor stopped working
 

Hi all. I had a similar issue where my clock was disappearing from the low-power mode standby screen, no double tap to unlock, and could not end calls. After reading this thread I realized that a drop (fairly gentle onto carpet while sitting) might have caused the problem.

I then noticed my screen was bulging up a bit. Hard to tell with the case but I could press the screen down about a 1/2 mm.

Having replaced my screen once I figured I would pop the screen off and see what I could see. If you want to do that, watch this: http://www.youtube.com/watch?v=9dxsTGpGRhs

I noticed the white plastic frame around the screen (that holds the screen down as shown in the video) had become detached from the screen glass allowing it to bulge up. This meant the sensor(attached to the white frame) was a 1/2mm or so away from the glass and likely was not getting a good reading. (you migh try simply pushing your screen down to see if the sensor works, though this probably wont work).

So to fix it, with the screen off, I used some CA cement (aka Crazy Glue) and a small brush (tooth pick would work) to reglue the white frame down to the screen.

After reassembling and rebooting, IT WORKED!

That is awesome, the trick with the camera is nice! The same trick I use to check wether the batteries of my remotes' are empty or not. Working the same way here!
Now I now that the sensor is connected to my phone correctly! Awesome

Awesome dude I won't disassembly as long as I'm not sure that it will work. But now I did the same! I pushed my glass and was able to bring it half of an millimeter closer to the frame. Which was enough to bring proximity sensor back working correct!
Quite good so I know I just have to disassembly und fix the issue with the white frame and glas!
