[SOLVED] Phone freezes/screen doesn't turn on while calling - Nexus One Q&A, Help & Troubleshooting

Hi,
I dropped my phone once, the camera glass broke and then the camera and the flashlight stopped working. The flashlight then flashed randomly at random times, I couldn't turn on the flashlight anymore. Most importantly, at calls the screen turns off and doesn't come on anymore, even if the other side already dropped the call.
So I decided to take off the broken glass. To my surprise when I dropped the device it started working again! But now, after a few months it just doesn't work anymore. I don't really care about the camera anymore, but I do need to be able to use the phone as a phone. Does someone know how to fix this? I don't care if there is a fix for me by removing the camera drivers or by removing the code that turns the screen off during calls.
I would really appreciate it.
Edit: Solved! After a week of looking around, my friend told me it was because of the proximity sensor and I had to edit build.prop and add the line
Code:
gsm.proximity.enable=false
After reboot, the screen didn't turn off anymore.

[Q] Call Issues

Hello. I've had this device for awhile now and it's probably the best phone I've ever had.. except I started to have problems with regards to calls just recently. I actually rooted the device about 2 months ago and am currently using the Rombie mod v2 (JPC), if that helps. Anyway, the problem happens in the middle of a conversation, where the proximity sensor somehow disappears and the speaker mode is activated on its own (or maybe it gets in contact to my skin, I'm not sure, since the screen is supposed to remain blank). After that, the device becomes unresponsive: the touch sensitive menu and back keys don't work, and neither does the screen itself..but the hard key home button works and I could still hear the other caller via loudspeaker. I force a reset and everything goes back to normal (I mean this call issue doesn't happen all the time). I don't have any screen protector to affect the performance of the sensor. Anyone can help me out with this? Thanks!

how to disable Htc sensation xl proximity sensor?

I have replaced the lcd/digitizer on my htc sensation xl and my proximity sensor has stopped working. Every time i make calls it goes to a black screen and sometimes the battery needs to be removed just to get it to turn back on. i was wondering if there was a way to disable the sensor through the software? or completely replace it?
anyone??

i once had the issue with screen protector on, but once i took it off, it worked fine.
definitely gotta be the screen's problem, it has nothing to do with softwares.
maybe you can try this app to disable the prox sensor http://www.androidzoom.com/android_applications/tools/proximity-screen-off_pjwz_download.html
if the app works for u, rmb not to touch the screen when u are making a call.

ok ,i will try this app and i will see if the phone respond positively .
I have a HTC Sensation XL and have also found the same issue when replacing the screen, both the speaker and Proximity sensor stopped working. After looking around for a while i found the comments on this site from a guy that obviously has come across the issue often:
psytechrepairs.tumblr.com/page/6
It sounds like a common occurrence that they fail with a screen replacement. I've also found that the light sensor and proximity sensor seem to both be on the same removable replaceable board (some sell it as a light sensor & others sell as a proximity sensor but they are both together):

Hope this helps.
I know this is an old thread however I have found a solution which i would like to share.
When replacing the lcd the way to fix the proximity sensor is to cover BOTH parts of the proximity sensor with Scotch tape and color the Scotch tape with a black Sharpie felt-tip pen.
works 100%
Hi,
sorry for posting here after so much time, but I have a problem. I smashed my display and ordered myselve a new one. Once I have changed it, the phone looked like everything is working just fine. Than I noticed that my Google Play Store is crashing, and a few apps were on my phone that I have deleted months ago.
My phone is ROOTED!!!
I decided to flash it again, the problem with crashing Play Store was solved.
After I realized my phone is acting crazy,first when I call someone the display goes black, and I cannot hang up or something. It looks like the proximity sensor failure. And even worse, sometimes the phone acts just like someone was using it, it writes opens apps, just like when someone is using the phone.
Any ideas???

[Q] screen going black when making or receiving call / camera no longer working

using HTC Google Nexus One, Android 2.3.4
This is very strange, but I noticed today that my camera is no longer working. I have no idea why, but it just goes black when I select camera. I have restarted my phone, took out the battery, etc. and nothing. Also, I even tried downloading other camera apps, and they won't work either.
Even more frustrating, though, is that my phone goes black when I make or receive a call. The calls do not get dropped, but when the call is over, I can't even hang up, as my screen is black. It's weird because my phone is still "ON," but I obviously can't do anything. The only thing I can do is take out the battery, put it back in, and turn the phone back on. Then, it works perfectly normal...until I make or receive another call. I have no idea what to do.
Can anyone help? I'd really appreciate it, as I use my phone for everything!
Hi,
I had very similar issues after accidentally dropping the phone (landed exactly on its face) . The sensors no longer worked, nor the camera and the flash light.
The problem during the phone calls is most probably related to the defect of the proximity sensor. However, I managed to use the phone with a bluetooth headset. The screen could be turned on any time, and, of course, I could terminate the call using the headset's hardware button. I used my N1 this way for over a year...
Few weeks ago I dismounted the phone, and realized that upper motherboard's connetor was detached from the main motherboard. After fixing it, everything is fine again.
I followed instructions from here: http://www.ifixit.com/Guide/Installing+Nexus+One+upper+motherboard/8025/1
I hope it helps.
Cheers,
Zoltan
Thank you for this thread
I created an xda account just to post about how this helped me.
My Nexus One camera had stopped working, auto-rotate no longer worked, and my screen was remaining dark after completing phone calls. So annoying. Was about to pony up some money for a new phone.
BUT... I followed the ifixit instructions that Zoltan posted above to take my phone apart, and low and behold, I had a loose connector. Plugged it back in, reassembled my phone without breaking anything, and it works! I have camera and auto-rotate again, and my screen acts normally when making phone calls.
Thank you!

[Q] [HELP] Proximity Sensor Problem leads phone to be Un-wakable! after any calls

Hi,
well i've looked in the similar threads but they were not this problem!
my Power Button was broken for the third time (that's a common problem for nexus one users i guess)
and i fixed it this time with another way (a repairman did it. the previous method, which i used twice, was replacing the logic board with a new one)
but after fixing it, my phone slowly began to recover that problem PLUS losing my camera,proximity sensor and LED flash. i'm sure it's because it felled down once and after that they happened.
He fixed it again but again...it dropped :|
well that person is no longer available and the thing is I just wanna use some commands or whatever else to disable the use of proximity sensor,
because i face screen off and no way to wake it up after any sorts of call! (unless i remove the battery,Use VOL DOWN+TRACKBALL+POWER BUTTON to reboot or connect my phone to a USB or a Charger.)
can anyone help???
PLEASE i'm really exhausted about this phone...i can't sell it...neither can afford more money!

Display stays off during call

Hi,
I just got my XZ a few days ago and experience only one issue: When doing a call the display turns off immediately, but when I put the phone away it's still off and doesn't turn on again. Service menu says the proximity sensor is turned on.
Anyone else with this problem and maybe the solution?

Most of the time with proximity sensor not functioning is because some Screen Protector is blocking it.
Make sure your custom screen protector isn't blocking it first, then if it still doesn't work properly maybe it's a hardware failure, should contact SONY then....
If it's the sensor or the screen protector (which has cut outs for the sensor), then why does it turn off the screen correctly the moment it put the phone to my ear?
It was the screen protector. Strange, other people don't have any issues with it.
So sorry Sony, your are great
Might be a little bit late, but maybe for others
worked pretty well on my Samsung S4.
download the app "proximity fix" from the playstore and run it.
Job done.
Hope that helps you or anyone who stumbles upon this!
