[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!

My screen goes blank while making a call

I just bought a Galaxy S from ebay and am facing this problem. Everything works fine on the phone and it doesnt look like there is any water damage. When I try to make a call the screen goes completely blank. I cannot disconnect the phone or do anything since the screen is blank. The only thing that I can do is remove the battery and install it again. Based on my research it seems like its a proximity sensor. I even went ahead downloaded Z-deviceTest and all hardware seems fine. I also upgraded to the official 2.3.3 from Samsung so I dont have a custom ROM, no root nothing! What can it be? Should I ask the seller for a refund or there are any tweaks for it. Any help is appreciated.

I'm not an expert, but seems related to a faulty proximity sensor indeed...

I am pretty positive that it is the proximity sensor as when I insert the headset calls can be made without the screen going blank. I dont have a screen protector and I tried to put some compressed air to see if that changes anything.

When making a call and the screen goes blank can you cover the proximity sensor for a while and see if its turning on the display? I kinda have the same issue sometimes and covering the sensor would normally do the job.

Same problem here, seems that plugging headset does the job. It is kind of lose or lose situation, even turning off (any idea how?) proximity sensor would not help as screen would be touched by ear Any other solution anyone? Or some kind of calibration? Check? Most applications from marked I have checked are crashing or showing 5cm from sensor regardless.

Screen not waking up after call ends or during call.

This started happening about two weeks ago. During a call when I pulled the phone away from my face in order to press the end call button, the screen did to wake up. I could not end the call. This has been happening quite regularly now. The screen simply does not turn on after or during a call. Even if the other person ends the call from his side, the screen on my phone does not start.
I was using the stable version of the official CM7 at that time so I flashed the rom again. Since that did not work, I did a clean installation of Mebitek's CM7 without restoring any backups. But I am still having the problem. I am now using the power button to end the call like a handicap person would.
I think something might be wrong with the proximity sensor or my battery. Since, I have absolutely no expertise of how the phone functions, I seek help from you guys. Please give me some suggestions.

try changing the proximity delay

Flash new rom.

Do u use a screen protector? I heard some might cause problems with proximity sensor.

Screen protector and wakelock

I used to have this same problem. The problem seems to be a combination of the screen protector/case getting in the way of the ambient light sensor and therefore not allowing the phone to accurately measure ambient light, and the phone going into some sort of sleep mode. I usually wipe my ambient light sensor off, and adjust my silicone case to allow the light to come in, but the thing that solved the problem for me permenantly was running the small app called wakelock to keep the system from going into complete standby. I am sure that this solution affects battery life, but I still get 10-12 hours between charges which is enough for me.
This thread talks about a similar problem, and this is where I got the idea to try this fix for our problem: http://forum.xda-developers.com/showthread.php?t=1491223

No no no guys.. don't bother with reflashing and stuff, that's not the problem.. I had the same problem and I googled it for months until I've learned its a Samsung wifi hardware related problem and mostly Galaxy devices are affected. Something is wrong when phone goes in standby. It continues to work but you can't wake it and you have to reinsert battery to get it on again.
The solution is to install a tiny app called Wake Lock, it's there on market.. it keeps phone awake even when you lock screen. My phone doesn't shut off anymore and I can finally rely on it. I don't have to think anymore and check all the time if the phone is off and if I'm going to miss a call...
The alternative is to turn off wifi before you lock screen but I think that most of us need wifi on all the time to get mails and messages on time

Galaxy mini doesn't have ambient light sensor.

My mistake

I am of course mistaken. It is the proximity sensor that is malfunctioning due to the screen protector and case.

Where to locate that setting?

My screen always turns off during calls . . .

. . . and I have to hit the power button to turn the screen back on. To be more precise, the screen turns itself off when I hold the phone towards my ear during calls, and it does not turn itself back on when I hold it away from my ear.
This is obviously some power saving feature that doesn't work as well as it should, like a gimpy proximity sensor. Anyone know a workaround for this ?
I'm on Three Musketeers Sense 3.6 ROM.

Well, ther is a proximity sensor there, near the camera on the top of the phone, on the screen side, and this screen-off thing is more like feature to save power and not to anoy you during the night when you talk to the phone
Don't know why it does that, maybe your sensor is faulty, but try to flash a different ROM and see if something changes, also make sure you don't keep your hand or finger near that sensor, just to be sure, i personally use this ROM and i don't expierience this issue.
Hope this helps

I actually have this EXACT same issue and it is really annoying me.. I have a feeling it is the senor that is faulty, because I haven't even rooted my phone yet.. so everything is all on stock....

Oh, dear
If only there was some way to turn off the proximity sensor like in my Galaxy S2.

If it is possible on Galaxy S2, then it is possible on any android phone , and it is, but there should be made a tool for that or a flashable zip, i'm not that experienced to tell you exactly what needs to be changed, but it can be done, that i know

Same problem here.
Changing roms didn't solve anything
Anybody have solution for this ?

If you have a screen protector covering it then it might be wise to make a cut out or take the protector off altogether.

as i remeber , you can write something in the build.prop that will disable proxy sensor

Im having problem that is almost same. After a long call(when screen is turned off) it turns off but screen or softkeys dont reply any way.
I have to turn of the screen with power button and let it be around 10-15 seconds and turn it on. Then lockscreen appears and everything
works. This is really annoying because I cant cut the line any way.
Not using screen protector and tried couple of custom roms. Allways have the same issue.

No I don't have screen protector or cover.
Problem is identified with proximity sensor itself, on App " Android sensor box " if you select proximity sensor it reads always 0.0cm no mater what you do with phone.
It seems like HW failure, will have to look at it in more detail.

I have tryed few Apps that will lock/disable proximity sensor but without success. It either acts the same or don't light the screen at all.
Anders can you help us with writing some code, I'm willing to be beta tester if you like ?

If you have issue with black screen after a call or something. Explain in detail how the error and what ROM and kernel And if you are s off and what hboot , then I will have a look

The problem is when you try to make a second call display turns off, phone is working you can talk, but you can't end the call or nothing because screen is off, so you have to turn it on or wake it by pressing power button.And it's happening only on every second call, so I make a first call, as soon as I try to make a second display turns off, and only power button wakes it, after that you can make the next call normaly, but problem repeats on second call.
Phone was stock on ICS 4.0.3, and making problems there. So it's now fully unlocked ( S-off ) Hboot is 1.28. I have tryed many custom roms, but the problem repeats
I think it's the hardware problem with proximity sensor.

I think too. Sounds like your proximity sensor is weird.

To continue the story, I removed the MB and when the proximity sensor is out of the case, it works ok. When I put it back in case( behind screen ) it doesn't respond again.
Cleaning didn't help, will have to find another one to make sure what is the problem.

I have fixed my problem thanks to this thread

Black screen after call - growing tired of this phone

Does anyone else have this issue? It's really driving me crazy to the point where I feel like ditching the Nexus 6. It's not even every call, but it is enough to annoy me. Pull the phone away from my head and the screen wont wake up. All I can do is long hold power to force a reset. It's really annoying. I've tried the proximity fix for 5.1 but it still happens. I can't set "power to end call" because also sometimes the phone doesn't wake the screen when there is an incoming call so I have to press power to wake the screen to see who it is.
Does anyone have any idea how to get around this other than the two solutions above? This has happened on both my devices (Original and RMA) and I just can't take it any more.

I sounds like a faulty proximity sensor. And I've observed intermittent behavior like this on previous phones (but not my N6). You can test this with a number of apps. I've used "Sensor Box for Android", but there are several more. Prox sensor is located near the top LH corner. With the app open and on prox sensor, passing your hand over it should register on the app.
You are so active on this forum that I won't even ask about a screen protector....

The proximity sensor seems to work fine under all tests that I have done. I actually use Tasker to utilise the proximity sensor to set ringer volume based on whether it is activated or not (eg in my pocket, proximity sensor CLOSE, set ringer high).
Its not every call either and multiple Nexus 6 devices have had this issue for me too. Proximity sensor works in every test

That's weird. I've had no issues at all. I assume you have the issue on the stock ROM too.....

I suppose I'll have to test though I don't really want to run stock.

What about disabling Tasker and trying it out.

Happens with or without tasker. It's pretty much always done it since 5.1
There are known issues with the prox being flaky on this device. I just need to find a way to overcome this.

Remember, we need to separate problem solving from the idea of how we want our phone to look and perform. Once you've identified the root cause, you can then decide what steps you want to take to solve it.

*Sigh* Yes I know. But it's so intermittent I won't know if it solves it for a looooong time. It would be quicker to return to stock, sell it and buy something else
I've literally never ran stock on the nexus 6.

Like Camera indicated, I'd try removing the screen protector if you have one and see if it's better.

It's not a protector issue.
Let's assume I've done all the obvious things except flash stock
Edit. I'm going to try and use power button ends call. Just to see of its an active call that causes it.
Hopefully it will happen when I can take a log cat but inise the phone very rarely.

Try this app in the Playstore.
https://play.google.com/store/apps/details?id=com.vorlan.screenoncall.free
I had a similar issue where the screen would time out while I was on a call and wouldn't wake when I moved the phone away from my face. I had to hit power button to wake phone and enter pin just to end a call. I make/recieve over 100 calls per day and it was getting old til I found this app. Works perfectly every time.

Thanks but that's not the same issue. Mine will not wake at all. I have to force a reboot to get display

You might give the app a try just to see. It keeps the screen on during a call but the proximity sensor still shuts the screen off unless you are on speaker phone. It may not work, but worth a try to keep your N6!

I've seen the same thing with my N6, display goes black (randomly, not even related to a call) and the only thing I can do is reboot. Haven't wasted any time looking for a solution, 'cause I don't think there is an easy one and there is no way to know if something you try is even going to work! I just reboot and move on.
Just posting to let you know you are not crazy and there is someone else out there with the same problem!!!

I'm not sure what you mean. I've been recommended this app before but I don't like the idea of mybscreen being on.
What do you mean it keeps the screen on but proximity still shuts it off? .

Thanks for confirming

Basically it doesn't let the screen timeout. Proximity sensor still functions like normal.
I would try it and see.
If it helps good, if not no harm. It definitely fixed my issue, even if my issue wasn't exactly what you're experiencing.

Well power button end call didn't help. I don't think it is a proximity sensor issue. Let's hope it happens when I can get a logcat. Unlikely. Maybe a job for tasker.

I had this issue too. I eventually thought it was tied to UV, but then I installed all stock and didnt change anything and it still happened. Maybe a bug in lollipop.
