Unresponsive screen during incoming call?

Hi,
Every now and then, while my phone is in my pocket and I do receive a call, I pick it up to answer and the screen is totally unresponsive. I can't slide to answer or do anything at all. I tried to power it off and on again quickly, and then it seemed to get back to normal and I can answer the call. Most of the time this happened during incoming calls. Anybody noticed this behaviour as well?
I read in the HD2 Android forum that it was due to the light sensor. But I'm not sure.
Thanks,
-Gus

I'm experiencing the same issue...

Me too. anyone?

Same here. It happened on the Nexus one as well. Perhaps is a stock android issue.

I have created a bug report. Please help me by staring this report so that it gets Google's attention.
http://code.google.com/p/android/issues/detail?id=13853

Any update/fix on this issue yet? I'm having this problem on stock ICS, CM9 & AOKP as well.

I have this problem even without having the phone in my pocket, when I have it on the table and someone calls me, I have to wait for five seconds before answering, because before that the phone is irresponsive and it FC's, which rejects the call. It gets very annoying.

I've seen a lot of problems on the web about this. It might be the proximity/light sensor.
As a side note, have you cleaned the upper left corner of your screen (where the light sensor is located)? Or at least make sure nothing is actually over it (maybe a case or plastic, screen protector, etc).
Any update on code recently? Are you on stock ROMs or it happens on different custom ROMs/Kernels (good to test with several kernels instead)?
Some apps like AndroSensor or Phone Tester can give you insights about the proximity and light sensor. You might want to check it out and test this with a flashlight or something, and see if values change.
From the bug report, has someone actually tested comment 44 and 46?
Or tested this app DHD Proximity Sensor Recalibrator?
Some have even noticed missed connectors when phone was dissembled (this requires more effort).

Am I the only one having serious proximity sensor problems (hang ups)

this has gotten to be a real serious problem for me - hanging up with my face while on a call. i am surprised this isn't talked about more here. any help would be appreciated! is it possible for the dev's to not only remove the end call button but the mute as well?

so far you are the only one that has ever reported anything like that,ya know it could be a hardware defekt

Nope I'm in the same boat as im sure are many others. I have only ever had it actually impact me I think twice on phone calls out of almost a hundred or so that I have had since I purchased the phone. All the others times though it was extremely annoying to keep hearing the click sounds of the screen turning on and off on and off on and off etc.
I keep hoping for a software update that addresses the sensitivity of the sensor, but still no
I also wonder how much the battery is affected by the screen turning on and off repeatedly while in a phone conversation...

I get the same. More on my right ear than my left, but it will often take a digit that I just typed for an automated system and try to dial it, resulting in an alarm tone in my ear during the conversation.

sorry but i have 3 different bolts,the 1st one was rooted stock had that problem but it also went into the brick loop so it got replaced,rooted that one but never had the prob again,this one has the bamf 2 prev 3 on it and no probs that is why i suggested harware cause my first one had major hardware issues

i get it too. but i dont call so much. so i dont really care lol

I too had this problem, and did some quick searching on Google. Stumbled upon someone who said to spray it with canned air to clean it out. To my surprise, it worked. There is just enough room between the screen and the body of the phone for dust/crap to get in and it hinders both the light and proximity sensors.

You might be holding the phone in a weird position?
THUNDERBOLT

Damn, you lean something new every day, this thing makes phone calls too!

I've had the issue too recently. But it only started when I returned the last phone to stock. Before that, I had a small issue with it, but it didn't happen often.

I have the screen turn on during calls, but I've never had a face hang up. Honestly I think the screen turns on for me, but can't be interacted with.
Scratch that just did a test. I guess I'm lucky. Then again I don't hold the phone flat to my face. So I guess I would never hit it...

i have had hangups, the mute button pressed, and a 3 way call started. i just tried blowing the screen out with some compressed air as someone suggested. it seems better - will give an update after some testing.

No issues with hang ups for me. Had that problem all the time coming from the X.

I have the same problem and have had it with every Rom I've run and stock. I'm surprised we don't have a way to adjust the proximity sensor yet, that's something I really miss about my Droid X.

After answering a call and putting the tb to my ear, my screen stays on.
Sometimes my ear dials numbers, sometimes the screen stays illuminated but doesn't respond to any touch! I have to toggle the screen on/off with the power button to get the touch response working again.

I have never had an issue. Been on mostly whatever the latest bamf release since rooting.

It happens to me whenever I forget the bluetooth especially after working out or anytime facial area is warmer then normal. I have a screen protector and clean the screen frequently.

I am having the same issue, so I called Verizon yesterday and they are sending me a new phone. I hope it works, because it makes talking on the bolt almost impossible.

this is the first I am hearing of this. No problems for me.

Have the same problem...its really annoying man....will not get a refurbished unit until they fix the reboots

Proximity Sensor

Hi, I have an issue slightly different than the ones I've found from searching. I have an unrooted Nexus 5 on Tmobile. the proximity sensor SEEMS to work, it turns the phone off when I talk but it CONSTANTLY hanging up, muting, or putting calls on speaker. I didn't have this issue with my previous nexus 5 and since I've gotten the new one (new out of package, replacement for previous which was stolen) I've dropped maybe 40% of my calls on accident and maybe 10-15% of calls accidentally put on speaker/muted.
Frustrating when you're in a phone job interview and you keep hanging up on the interviewer. I tried using a friends bluetooth ear piece for awhile just to see what would happen and it just did the same thing except in my purse/pocket.
Is this maybe a sensitivty setting I can adjust or should I take it to nearby T-Mobile store to be serviced/replaced?

Do you happen to have a screen protector on?

There isn't any settings you can change unless you root. As the other poster said, the most common culprit is a screen protector that doesn't have a hole for the sensor or is misaligned.

No screen protector but rooting isn't an issue I've just been lazy and haven't done it yet.

[Q] Bugs while on a call

I've had 3 Nexus 5's so far due to one RMA and lastly because of a mistake on Google's part. But with all 3 Nexus 5's I have had two bugs that have been driving me nuts. I was curious to see how many people have had the same problems and if anyone knew of a fix. Bugs:
1) Keypad buttons being pressed while on a call. This happens almost every call. It seems that the screen is still active even if the proximity sensor turns off the screen. I haven't been able to reproduce it on purpose, but every single call I take I hear buttons being pressed. Sometimes it's like my notification bar get's pulled down, then the clock is clicked and I feel all these vibrations and ringing sounds and I look down at my phone and I'm in the date/time settings. This happens even if I don't have the dialer keys open. Weird.
2) Say I'm laying in bed and I answer a call. It seems as if there is some sort of setting for the accelerometer that if my head is tilted too much it's as if the microphone stops working... almost like the phone tries to switch to the second microphone (the one not normally used for phone calls). I can't tell you how many times I've been in bed and get a call from my wife (who works night shifts) calling to say goodnight and if I ever put my head back on my pillow she can't hear a word I say. As soon as I lean forward again she can hear me.
These are two problems that I have had with 3 different Nexus 5 phones. I've experienced the same problem with both Franco Kernel and the stock kernel. I don't know what else to do but it's driving me crazy. Anyone else seen these problems or know of a fix?
Thanks in advance.

Try turning your screen off during a phone call and see if there are still key presses being made. Depending how you hold the phone, the proximity sensor might switch the screen on during your call and could register key presses from your ear. The sensor is on the right side of the phone and will "miss" your head if it's behind it.
Unless you're leaving the digitizer enabled (tap2wake etc.) it shouldn't happen.
The mic issue while lying down seems to be common. Your head/pillow blocks the sound and noise cancelation wigs out. You could alter the way you hold the phone while lying down so the secondary mic at the top sticks out more. Personally, I just sit up and haven't had an issue with the noise cancelation since.

Inconvenient Mute button during phone call

Anyone having the same problem? When I'm picking up the phone and pressing it against my ear to talk, sometimes it hits the mute button.

Ditto... I do it DAILY!
Oh my word, I hate that... I do it all the time. I wish there was a fix. My #1 issue with the phone

Yup same here! It happens daily, so much that I need to almost automatically check phone to make sure it isn't on mute before I answer or make calls. Hoping someone has some kind of fix.
EDIT: Just occurred to me that the proximity sensor is responsible for turn off screen before it hits your face precisely to avoid this problem. I looked at mine and the hole in my case to sensor was filled with dirt. I just cleaned it out and after 5 mins, it seems to be much better. Time will tell, but just wanted to pass it on
