Proximity sensor not working after iPhone 6 screen swap.

Hello my Ifixit Friends.

Changing the screen on a customers Iphone 6 and I can't seem to get the proximity sensor working. I've taken it apart 8-10x now, ensure that the plastic "holders" for everything is positioned correctly and that the proximity sensor is dust free. It just doesn't work..

Front camera works, the light sensor works. (Auto adjusting brightness) everything except turning the screen off during calls...

Any tips? :)

P.S: All componets appear to be fully functional and I have no other screens / parts to test with currently.

I used to have issues all the time, Then i changed up how i pull the Proximity Sensor out, and have done 100's over the last 3 months with out a single one not working, and no i didn't need tape or heat. The way i do it, is to take your tweezers, and place it right between the two cubbies that divide the proximity sensor and the other sensor up. and gently lift it out of that cubby. After that is free i take my pry tool and slide it under the speaker microphone. If it doesn't slide under it easily, i stick the pry tool under the rubber housing, and remove the whole rubber housing that the speaker microphone is stuck down to. I have bent them kind of good some times trying to get it out and have cause no damage. I believe its just all in the technique you use to pull the prox. sensor out of its cubby its stuck down in, and i also transfer the little plastic frame that holds it in place. Hope this helps everyone out.

Hello my Ifixit family.

After having repaired quite a few Iphone 6s now I've found a solution to the most common problem with the sensor.

While extensive testing I found out that the light leakage is caused from inside of the phone. Simply adding a piece of electrical tape between the internal speaker/camera where this is a large gap stops the light from the LCD from reaching the sensor, which is the problem. (Note, this leakage can easily be tested by making a voice memo, changing the speaker in the top right so that sound comes through the internal speaker and put a tape piece/something dark over the sensor on the front side of the screen. Then take your free hand to the internal part of the screen and cover up areas until you find the leakage. :) )

I take a piece of electrical tape, double over it (so both sides are sticky, so to say) and place it over the ESD protection of the battery contact. When you place the screen down the tape covers the hole perfectly and I've yet to have a problem with a sensor flex since.

I hope this helps some one!

Here's the pictures of OUR stores normal "leakage" spot where we place tape.

However, the leakage may vary. I had another problem today which was on the opposite side of that of which it's normally on.

The circled area is the entire area you need to ensure is "tight" so that no light leaks into the area.

Please note, the Iphone 6 in the picture is a water damaged phone that is irreperable. We are aware of the water damages you may see in the pictures. ;)

Unfortunately any of your solutions did not work. I called my supplier (they are refurbishing the lcd's) and he told me it is caused of the wrong placed proximity plastic stuff.

Thanks to all who contributed. I had similar issue with the proximity sensor on iPhone 6s. The ear piece heats up and sensor fails to switch off the screen . I replaced the complete screen from another iPhone 6s with has faulty a board and it's works perfectly. I tried interchanging the sensors. The sensor fails to work on the new screen . The sensor works/screen goes off when I placed my finger on top of the screen but not on the sensor.

Most at times Sensor is not the problem.

Problem : Screen ( most of the screens are the cause)

Solution: Quality Screen / New Sensor

Hello every one,

I would like to say that I solved the problem by changing out the sensor. The parts I'm currently using for Iphone 6 are original, so no worries about quality. I have no idea why/what caused the old sensor to stop working as I inspected it very closely with the new part I bought and they were identical.

However, after several hours of changing back and forth I deemed the old sensor broken and replaced it.

Thank you for your tips reguardless and I apologize for my late reply. :)

You lot are just about to love me to bits, because I'm going to save a !&&* of a lot of money and grief.

I've checked out the sensor and the cause of this problem and it's none of the answers above.

If you look carefully at the old screen, left behind is a double sided foam where the prox was.

What's happening is as you lever the flex out, no matter how carefully, the foam pulls on the prox such that it damages either the solder connection, or the leads of the actual device.

If it's the solder connection, a quick all round with a rework wand or possibly soldering iron will remake the dry joints and get you working again.

If the leads have broken, game over sadly, you'll need to replace it.

The theory of putting tape around it and it then working isn't to do with light, simply that the tape is putting pressure on the joints and they work again.

Prevention is better than cure though right?

Just before removing the flex from the old screen, simply heat the front top of the glass until it's too hot to touch, be careful not to melt the flex leads!

Leave for 30 seconds

Gently pry the prox out. The foam is now soft, it'll give way easier, making it less likely to damage.

I'm here all week, don't forget to tip your waitress ;)

can you provide a photo? I only see glue residue, no foam.

The biggest issue I've had with the proximity sensor on iPhone 6 (and 5/5C/5S) is that is breaks off from the flex cable if I'm not careful enough. Sometimes it seems like it's already broken off when I simply touch the flex cable. The plastic holder for the sensor just doesn't want to let go go of it.

cheers.

さんによる

Surely there is no foam in the 6 and 6plus. I've encountered two different solutions to the issue:

1. Replace the flex cable because it's damaged.

2. Relocate the sensor or fix the bracket with a bit of glue to make sure it's in the right spot.

Sadly I destroy too many flexes, so I aways have a few in spare.

This issue happened with a 6s I was repairing and the only solution was to replace the screen. We spoke with our supplier and they said some manufactures have a proximity sensor issues with the 6s screens.

Hello,

On iPhone 4 this problem occurs often when the screen quality is not good and the sensor filter on the screen lets too much light arrive on it.

Did you try with the broken screen again to see if it doesn't come from the quality of the new screen ?

I've repaired over 200 iPhone 6 screens since the beginning of the year. I still contend that the front camera/front mic/proximity sensor flex cable is extremely fragile and that extremely slight bends, pressure, etc. will damage it. The main part of the cable that sits directly under the ear speaker (when installed) is very stiff and I believe that the copper wires inside really don't want to be tweaked in the slightest. The best method I've found to remove it and not damage it is to use an iSesamo tool (because it's the thinnest) and insert it under the main part of the cable. Position the tool so that it's corner matches the corner of the flex cable (see photo). Then place the finger of your free hand on top of the flex cable and hold firmly while you very gently, pry straight up with the iSesamo. Your finger will help keep the cable from bending while you pry up. The goal is to lift the proximity sensor out of it's hold and then go back and pry the hold off separately. This is different than a 5/S/C where you can pry in a way that keeps the hold attached to the proximity sensor when you remove it. The new problem I have run into with the iPhone 6 is that apparently the front mic can test just fine immediately after the repair and a few days later it stops working. Replacing the flex cable fixes it immediately. I'm not really sure what causes this to happen but I'm trying to be even more careful when removing this flex cable.

  • I (think) I uploaded the photos but it doesn't seem like they are posting.

That's why you need to heat it up.

Some don't have foam it seems yes, but all have adhesive which has to be softened up. It won't rip the sensor off then, it just kind of turns to goo and it slides away.

Was the screen replaced due to water damage ?

I had an iPhone 5S that I changed the screen on, due to water damage - the screen I bought was also apparently a genuine Apple item and I had no reason to dis-believe this.

Everything worked on the phone apart from the prox sensor that turns the screen off when it's against your face.

Reading through these sorts of forums, I doubted the screen and tried various fixes without any success.

I then bought a new £5 front camera, loom and sensors and they worked straight away.

Moral? It's not always the screen! And next time, buy the pre-assembled one which had all the parts on but was £50 and not £25. Would have saved me a lot of time and grief in hindsight.

I have replaced about 8 iPhone 6 4.7" Screens so far only have had 1 original proximity sensor work after replacement. To fix the issue I have had to replace the Front Camera and Proxy Sensor Flex Cable. Replacing this fixes the issue. As stated above by another user, No idea why this happens, I have tried Screen replacements with the Battery disconnected and connected and makes no difference.

if anyone has any more info would be much appreciated. Thanks

I agree that this is because the replacement screen assemblies let too much light through the prox sensor hole. The aftermarket prox sensors are probably less sensitive, which is why they are working. Something to try that worked on older iphones: use a piece of black tape (or scotch tape sharpied black) and poke a very little hole in it. Then place this over the prox sensor window on the phone assembly. Haven't had the chance to try this but will later this week...

I know what you are talking about but in this case I believe something else happened, we here in our store think we had a dodgy batch of iPhone 6 screens initially. Because I tried putting the sensor flex back on the old screen and testing it and it stopped working on the old screen as well as the new one. I even tried putting my finger over the sensor while it was attached and still nothing. We have done another 15-20 since my last post and not one has had an issue. We also changed supplier for screens after my last post.

== Hello.

I too have had the same problem, but I solved without having to replace the proximity sensor. In practice, in addition to the filter "white" that should be removed from the screen original, must be added also the filter "reflective" that is used on the proximity sensors of iphone 4 and 4 / S ==

Another person here with the same issue first time I attempted an iPhone 6 repair. Upon extremely close examination, even though I was quite careful, the flex cable was damaged upon the removal of the proximity sensor, and aside from not working, the proximity sensor would get VERY hot when you put the phone up to your ear. Tape did not work.

There is also another piece that doesn't usually come new iPhone 6 screens that could be easy to miss and cause light leak. Directly adhered to the speaker earpiece mesh is a black plastic cover that needs to be removed from the old screen (which you can do by pushing out the mesh from the front of the screen and separating it afterward.) Here it is pictured on the bottom (yours wont have the red tape on the corner) The piece will clip into the mesh on your new screen, that is of course if your new screen even came with a mesh.

To prevent issue, use extreme caution when removing that ribbon cable from the old screen, make sure you don't lose the rubber piece over the ambient light sensor, and the previous recommendations of the iSesamo tool, along with carefully heating the front glass by the earpiece are great. Overall, I fixed my first shorted out one with a replacement flex cable, since I didn't want to bother with micro soldering of the leads / flex cable copper wires, and I haven't had a repair not work since.

TLDR: Proximity sensor is probably broken, buy an aftermarket replacement on eBay for $8 and be extra careful.

Hi,

Yesterday, after a mesh replacement I had the same problem. (The old mesh was very dirty and it was impossibile to ear other people during a calling)

I tried the scotch, another sensor, re-assemblate.

I was very careful with all and I don't think that I broke the connector on the motherboard.

Camera, light sensor, speaker..are all working great.

Maybe a phone recovery can help?

Please help me!!

I'm an amateur, and this is only my 4th iPhone screen replacement (have done 5/6 times on iPad as well, since iPad is that mostly used by kids).

Now, all my previous attempts with iPhone 5, 5s, and 6plus has resulted in this very issue; i.e. Proximity sensor not working.

Even for this (i.e. iPhone 6) l faced the same issue. I genuinely hoped this won't happen this time as I had took extra care.

Coming to solution, it took me close to three hours trying various things posted in this forum as well some others.

What it finally worked for me was, GLUE the proximity sensor cabin (sensor was inside that) to the proper place. I know, this might not have worked for some, whereas something else might have, or maybe none had (just as it didn't for me in my previous 3 attempts).

Nonetheless, given that this is an easy solution, and the relief that came along with, I thought to share it over here. Good Luck

I had this problem with a few phones I repaired.

If you are using a non OEM sensor with a non OEM screen, make two small scratch holes in the paint on the screen where the proximity sensor sits. You should clearly see light through the scratches. Always glue the original sensor holder into the correct position.

If you are using a working OEM sensor with a non OEM screen, darken the inside of the glass where the sensor sits with a black sharpie. I have noticed that the OEM sensors are prone to faults once removed so I find it better to use non OEM sensors as they are far less sensitive and cost very little.

I have not had a problem since adapting this method on 100+ repairs

in rebuttal, i strictly use OEM screens and OEM sensors, properly re-glued brackets and when possible re-use the VERY small foam gasket that sits within the bracket and have had very high success. little bit of heat goes a long way with re-using the foam gasket. (theres a reason Apple added this gasket)

So i work at a batteries unlimited store, of course I've been doing screens for months and never had an issue. I soon ran into a problem that had me stumped. I replace 5 to 6 screens a day and never have a problem. So the other day i did an iPhone 6 and have to switch everything from the old screen to the new screen and then ran into the problem of the proximity sensor not working. Usually we have a check list of things we check before we change anything to make sure everything works properly before and after, with the screen in the condition it was in i was unable to check the sensor to see if it was working. Switched everything over and not working so tried a new sensor and still having the same problem with it not working.....HELP!!! Mind you my customer drove miles for me to fix his phone so any answer or possible conclusion helps..

If you tried a new sensor, the problem must most likely come from the new screen. Have you tried another screen ? Since you repair 5 to 6 phones a day, you must have other screens, right ?
