IPhone :: Proximity Sensor Malfunction
Jul 13, 2010
I've noticed that when I talk on my left ear (which is how I always talk), I have CRAZY problems with the proximity sensor. I cannot go through even ONE call without either putting them on speakerphone, hanging up, going into contacts or dialing numbers by accident.However, when talking on my right ear, no problems at all it seams. I don't know why but it's annoying as I can't talk on my right ear, it just doesn't feel right and I'm not used to it.What have your guys' experiences been with this?

Noticing someting wierd with my new iPhone 4 - the proximity sensor doesn't seem to work well (or at all..)When the phone is up against my ear or if I'm cradling the phone between my ear and shoulder the proximity sensor should disable the screen and touch controls until it detects that I've pulled the phone away from my head. My iPhone 3G excelled at this. My iPhone 4 however seems to want to keep the screen on at all times, causing "cheek dialing" issues, mostly trying to initiate FaceTime.
Anyone else experiencing this?

So I've had my iPhone 4 for a day or so now and have noticed the proximity sensor is much weaker and you have to be pushing your head against the actual phone and that when I have speakerphone turned on the mic does not work. This problem is only confined to speakerphone, the mic works in every other situation even on skype speakerphone works.

I have fixed my proximity sensor and can now make calls without hanging up/muting etc. I was having severe problems with the proximity sensor on my IPhone 4. During calls my ear was hitting mute, end call, face time etc. Today I had the hardware replaced at a retail store and restored a backup. The problem remained. Then I read a post on this site suggesting resetting the network settings and thought, why not, Apple had no fix.
Before I started I tested and recorded that the proximity sensor required my hand to be about 5mm above the sensor before it kicked it and blanked the screen. Then I used Settings/General/Reset/ Reset network settings. After this the proximity sensor worked at about 3cm under exactly the same conditions. I have continued using the phone including setting my WiFi password which had been cleared.
This wont clear everyone's problems but: As it takes 30 seconds and doesn’t wipe your phone, give it a try before sitting on the phone to Apple, driving to the Apple store etc. Besides they don’t have a fix yet. My testing pretty much proved that for me, changing hardware didn't help but a configuration change did. Therefore even though other users may have other setting, which in combination with a complex bug mean this fix doesn't work for them, it is a software bug in some cases, probably most. So Apple should work this out in the end and post an update to the OS.
If this fix doesn’t work for you and you want to do something, test your sensor by starting a call, leaving the speakerphone off and putting three fingers over the top of the phone covering the entire phone above the screen. If the screen blanks when your hand is close but comes on when less than a couple of centimetres away, then see if a software fix helps. Take a backup and then wipe the phone and then retest.

My big beef with the phone is the proximity sensor and if I'm in a call longer than 5 minutes, I can pretty much rock the phone off my ear ever so slightly and the screen comes on. My only fear is that once I get it there, the genius won't be able to replicate my problem and tell me it's fine.
Basically I'm asking for advice/tips on what to say to this guy (I've never been to an Apple Store and I haven't heard how nice the people are in the Florida Mall) so I don't overreact to whatever this guy is going to say to me.
I'm also curious to know if anyone else has had Apple replace the phone for this specific issue because I seem to be the only one out of my batch of friends that is having this problem. Even when I use their phones, I cant seem to find an issue.
Again, any advice is greatly appreciated.

So I recently upgraded to IOS 8.1.1 and since I made that update with my iPhone 5 32gb my proximity sensor has stopped working and has caused me to face time or end calls or mute conversations with my cheek while on a call. I have done a soft reset, and rebooted numerous times and the problem persists.

I've had an iPhone 3G for one year and a half. I Opened it up a few months ago to change the back cover, which was broken; and I broke a bit the plastic piece of connector 3 of the mother board (see at the Attached image); However, It worked perfectly... Until now, that I've reopened my iPhone to change again the backcover (false covers aren't very good...), and when I finished... Noticed that the earpiece is not working! I can't hear anything while calling! I know that the connector 3 of the screen is the cause, because proximity sensor isn't working neither...
But my question is:
Is there any way to know which part of the "connector 3" has been broken? The MoBo, or the Screen Flex? Because if it's the second, I can replace it for a few bucks, but if not... :S Or... Is there any other connector that I could damage or put badly, so they are doing contact with wrong pieces, etc etc? Notice that I had to disarm the whole iPhone to change the cover... So perhaps.

Earpiece and proximity sensor do not work. I can hear people fine when they are on speaker. The screen does not turn off when I place my hand over it.

I wonder if majority of dropped calls on iPhone 4 is the result of "proximity sensor issue" and not "antenna issue."

The proximity sensor on my iPhone 4 has been driving me crazy and I've been holding the phone to my left ear the same way as I've held every iPhone before with no problems. I thought what would happen if I moved it up a bit so the sensor was at the top part of my ear instead of at the hole part of the ear. So far, in the 3 calls I've made, it seems to have fixed it. Will have to see some more of the next couple days and it does require you to think and focus on how you are holding it but at least I can use the phone.

I noticed that if I cover the sensor with my head or my ear, it does not work, but if I use just about anything else that does not interfere with the capacitive touch screen then it works fine. Does your new phone do this too?

I thought everyone might like this one. My wife has incredible problems with the proximity sensor on her i4, and last night she came up with a solution. I thought it was pretty clever, so I am passing it on here. She said that when she was in a call somehow she got switched to contacts (we all now how this happens, but she was unsure what she had done to make it happen) and had the green bar at the top (press to go back to active phone call bar). I explained she had gone into the contacts section of the phone while on a call. She found that since the phone activities were no longer on the screen, no more mutes, hang-ups, face dials, etc. occurred for her no matter what she did. So for the time being her resolution (although this is basic, it will work for everyone) is to leave the active call, while still on the call, to keep the phone actions from being activated by her face while on a call. it works for her, makes her happy, and we were able to talk for an hour without any of the past problems (she is across the country and no where near an Apple store to have them look at it, so in the meantime this will work for her). So if you find yourself in this position, it may be a handy work around in the meantime while waiting for the official fix from Apple. I just though it was a clever idea (usually she doesn't think about things like this) and since it works for her and enables her to make calls without problems, I am ecstatic (at least maybe she will stop complaining about the issue, yet I have to remind her that SHE was the one that wanted the phone so bad, and now she has it so bad!)

Ok heres my problem. About 2 weeks ago i went to the Apple store because i got an iPhone 4 with probably the worst proximity sensor on the planet. Literally i hold it up to my face and dont move a muscle and the screen flashes on and off. Its literally caused me to add calls at 3 a.m and hang up on 50% of my calls. So i asked if i could swap it out and the guy working said i should wait for the software update and getting a new phone would still have the same problem. So the problem is now my 30 days is up, and what if the update doesnt fix it? Do you think theyll still let me return it? ATT store wouldnt let me swap out either.

When i'm on a call, with the phone to my ear, the screen wakes up and FaceTime/Speakerphone suddenly turn on. Anyone else getting this? And I had the 3G before so i'm not 'holding it wrong' or anything..

Got my dodgy iPhone 4 changed at Regent Street Apple store today. Should I set up as new phone or use the backup? Genius in store, after prompting, thought maybe best to start from new. Any ideas anyone out there who has had to get a swap? Will probably restore from backup but will I reintroduce reception and proximity sensor issues?

Got my Defender the other day. I noticed that when the phone is in the case the proximity sensor stops working. I take the phone out and it work fine. I emailed Otterbox and the guy said to clean the plastic window. Really?? you dont think I tried that before sending the email? I am going to try my brothers case to see if its the case. My brother told me that he had the proximity sensor issue before the case and now his works fine. My last step is to reload 4.0.1 but I have to figure out how to get a video off the phone first.

LG g4 proximity sensor always on when screen is turned off.
If the screen is on, but before unlock, proximity sensor is on as well. It will turn off only after unlock the screen to home screen.
Will it cause battery drain and infrared light burned out/dead after being *"ON" all the time?
It is infrared, so you can only tell if you use another camera or phone look at it. it is easy to test, just look proximity sensor with another camera or phone camera (that can see infrared, can be test with your TV remote)....

My problem is the screen goes blank when making a call and does not wake up. I cannot therefore use the keypad or terminate a call.I replaced the screen a while back and everything worked fine for 5 months until now.I am looking to disable the proximity sensor as it does not work so the screen is then on all the time when making a call.I have not been able to do it through settings so is there an app that would do the trick.Model is D855

I have an LG G4 since December 2015 and like many people I found out that "Double tap" to wake the device does not always work.So, I ditched this feature and used only the power button to wake the device.The problem is that even the power button does not always wake the device, many times, a second push being needed to successfully wake the phone.I even called LG support and scheduled a visit to the service center.
Today I think I found the reason why the power button does not always work, at least for my device.I usually leave my G4 with the front facing down, on the desk.When I hear a notification alert or the phone rings, I grab the phone and press the power button while it is still facing down on the desk. Many times in this situation the phone will not wake up.So I started thinking it has something to do with the proximity sensor.To test this, I covered the whole top of the phone (front side) with my palm and pressed the power button. No matter how many times I would press it, the phone will not wake up. At this moment, I will start distancing my palm from the phone while pressing the button every second.Only after the palm is at a considerable distance from the proximity sensor would the phone wake up.I thought about a feature in Android "prevent accidental wake up" but Marshmellow does not have this feature or I could not find it in Settings.
I tried searching the web for other G4 users having the same problem, but found none. Found a couple of posts about the button being defective and a couple of posts about screen protector causing the screen to not wake up after a call or interfering with taps on screen.
So the question is: It is normal for the phone to NOT wake up using the power button if the proximity sensors detects something close to the phone, like the surface of the desk?I could understand "Double tap" not working while proximity sensor detects something and that is why I am not using that feature anymore, but power button?It is working as intended? It is only my device?

 So I cracked my phone a while ago, had the screen replaced at a local place and the screen looks fine, the phone functions almost 100% perfectly.Â
Â
The thing that bugs me is that the phone seems to have the proximity sensor always on. When I answer a call, the screen turns black, and I am unable to turn the screen on until the call ends. I would rather just have the proximity sensor completely off. I just want my screen to be on when I'm on calls, or at least able to turn on with the power button.Â

I accidentally dial a number and the entire phone locks, I cannot end the call and I cannot do a hard reset.
I really do not want to learn how to live with this sensor. I would just like to switch it off.

I have just bought a Torch 9800 but am annoyed by the failure of the proximity sensor to detect my face during a call. I cannot say that the sensor doesn't work because when I made a call to myself and use my finger to cover the sensor, it detected it and blank the screen. It also worked when I place my palm near it. However, it never works when I actually put it next to my ear. I think may be it's because I have black hair and blackberry designers never expected that. To solve this problem temporarily, I need to cover the sensor with my thumb during calls but it's uncomfortable to hold the phone that way.

Where the 950's proximity sensor is located? I want to make sure my screen protector isn't covering it. It appears to be to the left of the camera. If that's the case then my problem shouldn't be the screen protector as whatever is to the left of the camera is not covered..
Whenever I dial a number my screen goes black as soon as I hit the call button. It does not wait until I put the phone up to my ear as my 920 and 640 do. I have to hit my power button twice to get the screen back. It's acting as if the proximity sensor is stuck on activated.
