Just this evening I noticed when I put my phone under a lamp with a bulb, the phone thinks the lamp is my face and doesn't turn off the screen. Are you guys experiencing the same thing?

I experienced the same thing though it happened randomly. I tried to put my friends sgn2 side by side with mine and his phone doesnt have this problem.
Is this hardware problem? How to fix it?

I don't know. Seems to happen on my note 2 randomly.
Today it happened to me in dim litted situation. So it seems not limited only on bright situation.
Yes, I had this problem some days back! Damn, I was going to wipe my device for this, then thought about un'smart' stay and just rebooted the device, got fixed!
Btw- The smart alert feature is also not responding for me sometimes! When I pick the device up from the table beside my bed it vibrates sometimes, but most times it don't. Don't know what's going on!

These smart features use the front camera as the sensor to determine the condition. Should there be any defect on the hardware, itu must be the front camera. But I find my front camera to work well on taking photos. So I wonder what caused this? software? I don't think so since I was using the same version firmware with my friend and only mine got that problem.
I have no idea what is the cause of the problem.
If anyone had these problem, please describe it here so we can get an idea what might caused these.
The software does what it can. It confuses our eyes with other things. it has happened to me. I think it's more meant for you to look at your phone and not turn off rather than being able to 100% distinguish your face in all situations and know to turn off the screen. Most of the time it works though. I'm happy! But usually to not waste battery I turn off the screen when I put it down.

So whenever I talk to my wife she always ends up hitting buttons on the screen. (mute, speaker, etc) I told her that the screen should automatically turn off and that maybe something was wrong with her device. As soon as I got home I tested it and it worked just fine. I couldn't get it to happen, light sensor was very responsive.
Somehow she manages to hit buttons and I have no idea how. I covered up the light sensor and tried hitting every button/screen area and nothing happened.
Has anyone else experienced this before? Is there something I can settings/mods wise to help?

Another funny thing is she said her boss at work has the same problem (female) and her husband has no issue.... Ha! I don't think they have Evos though.
my wife was having the same problem and we narrowed it down to her hair causing interference with the screen sensing that her face was against it. dont know if that makes sense but seemed logical to us and now that she tries to be aware of it and move her hair out of the way the problem doesnt seem to exist. hope this helps.

Weird! Does the screen actually turn on then? I should watch the screen next time she makes a call on it.
yeah the screen was turning on while she was using it. i think whenever she would basically readjust the phone against her head it would happen if the hair would cause interference...again i'm not claiming this is some scientific answer but its what we found seemed to be causing issues for her

How would the earrings affect it?
I think it's actually the proximity sensor being highly in tune to how close it needs to be to the ear/face. It takes very little movement of the phone during a call to trigger the sensor and turn the screen back on. They probably don't even realize they're moving the phone as much as they are.

During a call, I pulled the phone away, moved it around, etc and watched for screen to come one. It did not come on easily. I don't get it.
I need to watch her during a call and test some things.
My sis has the same issues with the moment, and I tried it out and it was fine. She does seem to use it outside her hair and does have a lot of earrings. Though this is the Moment, it still runs android and has the sensors. I'll let her know and see if she'll enjoy her phone again lol.

Still not sure what the issue/solution even is.
She picked up my phone last night and accidentally hung up on the person during the call! I didn't get a chance to see what happened...
She's starting to hate these phones. I need a solution.
Not a joke...but are these ladies blonds? At start of thread I was thinking hair color or earrings too. But earrings shouldn't impact the sensor as it is up top of phone and earrings would be down toward the screen.
But...if their hair was very light color...and they had phone only loosely pressed to head, I could 'guess' that the hair had enough light reflecting through it to set off the sensor.
Another thing to check on the earring side....what part of phone contacts first...do earrings hit the screen before head covers up the sensor?
My wife had dark brown hair :x
My wife too. Dark brown hair. With and without earrings. Swapped out one device, same problem. She even made it happen on mine.
I have seen it get in a mode where the proximity sensor seems to get reversed. Near head, screen on, away from head screen off. A button gets pushed at some point and then when the screen is on you can't un-mute, un-speaker, or answer a returned call from the one she just hung up on.
I think we are going to have to get her a different phone
I have the same issue but it only seems to come up with AOSP ROM's (Cyanogen & UD)
If I call Sprint and hit the prompts followed by putting the phone to my ear it presses other numbers. I think there is a delay in the proximity sensor that's causing this. I don't have long hair and my face is clean shaved so it's not that.
If I go to show someone that when everything works perfect. It's like when you call tech support for Dell, Netgear, etc. It works when you're on the phone with them and when you get off it doesn't.
I've noticed this in the past. If you are talking on the phone and you cant it just a little bit away from your ear, towards your face, you can see the backlight come back on. Also, hair can carry a static charge. So if your ladies cant the phone and the screen turns on, their hair could trigger a button press.
Good day,
It seems this issue has been discussed widely and regularly but I couldn't find a solution that works and I hope you can assist.
My -rooted/Redux- Desire's screen goes off when calls are made regardless of whether it is close to face or not, in addition it doesn't come back on until the call is ended -or battery is replaced- and obviously this can only be done by the other party as my screen stays blank and unresponsive..
Any thought or help would be greatly appreciated..
Regards.
Do you use any kind of sticker or a case which is near to the sensor ?
I had similar experiance with a sticker before. for 6 months it didn't cause any problem but after 6 months it caused some with problems with light and proximity sensor.

Maybe the proximity sensor is knackered. Could be your phone that needs repairing. On the other hand you should be able to turn the sensor off if its getting too annoying by going into settings calls or display can't remember precisely buy there should be an option there to turn it off. Hope it helps.

There might actually be a dust particle under your digitizer, which caused the proximity sensor to malfunction
That's what my Desire has for a few months now.. Drived me crazy, until I started using CM7 which allows me to switch the screen on by pressing the power button during calls. But sometimes it still doesn't respond. Plugging in a powered USB cable is another solution then.
Anyhow, check if your proximity sensor is working by using Z-DeviceTest for example. If the sensor is indeed not working properly, there might be some dust on the sensor. Take off your backplate and blow around the power button area. Worked on my phone the first few times it occurred..
Hope this helps!
Hey guys, I just picked up a sgs2 and the phone is amazing. The only real problem that makes me want to throw this out the window is the darn proximity sensor every time I talk to someone. If it is on my left ear, the screen goes blank and everything is fine. If I try to talk using my right ear, the screen goes blank and then after 3-5 seconds, turns back on and then off, etc. It is a never ending process and I have tried to position my phone in different ways on my right ear to stop this with no luck. Sooo frustrating. Anyone else come by this issue or heard of anything like this before?
never had this issue....what rom are you on?

Maybe your right ear is way smaller than your left jk. I dont have this issue but the sensor is on one side of the phone it could be an issue with the way your right side comes in contact with it.

Just stock, I am beginning to believe I am deformed Lol must be the case
OMG! sorry but that made me crackle in LMAO
anyways... if you notice on the phone the sensor is on the Top left, where the FFC is located
so probably when you use it on the other side, it's not detecting any face/ear/obstacle for it to activate itself
The screen on my note 3 suddenly showed a green hue color. I took some screen shots to show but after I pressed the power button(standby) to turn screen off then back on again the green hue disappeared?
So thinking the pictures would still prove the issue, no I was wrong the screen captures I took with the green hue are also fine . Not sure whats going on...Perhaps it is hardware related hence why it does not show in the captures. Basically all the blacks had a green hue to them / in fact were green .
Today is the 14th day for me to return or exchange the device at t mobile. Please advise. I did install some dark wallpaper apps but deleted them yesterday, was using normal stock wallpapers. I am not rooted.
Do you think it is hardware related? I believe if it was software related then the screen captures ( which I took when screen went green) would also show the green hue.
Had the same problem here but mine had a pink hue.Try to reset the colors. Just type *#0*# on your phone dialer and use the 3 colors for 5 minutes each, it will reset the pixels.

It went away when I pressed it on standby and back again.
What gets me concerned is that when I took a screen shot when it was green it didn't show on the picture after it remedied itself.

So have the problem gotten worse since then?
I have seen it now and then. Often happened when I was on the phone and closed and opened the lid.
Happened now that I opened the lid after attaching it to the charger.
Should I expect it to get worse, and therefore return it for a new one or will it be a rare bug now and then?
Reading mode enabled?

Hi,
I bought mine in October 4th 2013, has occurred twice so far. Taking screen shots does not show it. I am thinking it is a software glitch.
Reading mode was not enabled. All dark areas of screen goes green.

If you are doing a screen shot, it is reading the state from the device and saving it. So later if you look at that screen shot and it looks okay it most likely is not software. If you look at the screen shot while the unit is displaying the green look and it looks right, then you most likely have a software issue.
Sounds like a hardware issue or perhaps some weird mode being set by software. I still think it is hardware though.

I perhaps hoped that you had answered my question when I first posted as this occurrence first happened on the 14th day of my purchase, so I had a choice to return to T Mobile store for swap out. Either way, only occurred twice so far, so I am not worrying too much about it. Shelf life for phone for me is approx 12 months max, so all is good thus far. Pressing the standby button afaik cleared it up at the times it occured.
I too have had this happen twice now and months in between. Happened after mj5 update could that be a cause

Doubt it, as mine is stock N900T that has no updates as of yet.
The first time I rebooted and it went away. The second time it was only like that for a few seconds and cleared up on its own. I'm on the at&t version

Mines does this once every few days apart, if I just turn off the screen and turn it back on it goes away. I also took screen shoots but they show fine in the gallery. I only seen it once on my wife's note.
I have exactly the same problem, the green hue appear, and turning off the screen or dial *#0*# and select one of the color to test the screen can clear that away. it happens once per one or two weeks for me. I'm worried that may be a hardware issues and that is a symptom before the device fail. Does any of you have this happened then your phone became not working ?
btw, It's seems happens after I changed to a magnetic flip case ,not sure if that's related, will try not using that case and see if that will gone away. Are you guys having this problem also using a case with magnetic flip ?
Hi, everyone. So I have an LG G4 for more than a year now and I am very pleased with its performance. I did have an issue with sometimes the audio is stuck after a call but I think it more has to do with bad reception as I noticed so its rare this days. However, lately something happened with the knock on feature which I cannot figure out at all. Sometimes it just doesn't work. I tap and nothing happens. The power on button is working perfectly but the knock on is unresponsive. I fiddled with the proximity sensor but it's not it. Sometimes it just stops working for 5-6 times and then it works and the again it doesn't. There is no pattern. When it's powering on the feature works with no hiccups but after that it's like the cpu forgets to monitor the process. I don't know. I have tried calibration and it works with no problem for a few minutes and then it goes back again to this stutter. Does anyone have any ideas about this? I am thinking factory reset but the hassle would be pointless if the problem persists and I am in no mood to install all those apps I have from the beginning for no reason. Any hep will be really appreciated. Thanks in advance.
I am experiencing the same issue but mine Knock on is a bit delaying.. for an example, I double tap on the screen and it gives response in 3-4 mins or not... I am suspecting from screen protector which has been mounted for almost a year, it could be corrupted(scratch) Give a try on removing the screen protector(if you have any)
It's a hardware problem. Many threads online about it

Is your case or temp glass protect over prox sensor. That can affect it bad. Also scratches on glass over prox sensor. If not. Then more than likely hardware related.
No the screen protector does not cover the prox sensor. It's cut out as it should be. I am starting to think it's a hardware problem. The thing is why now?!

They are mostly sensors just like on a car. Sometimes it's just there time. Electrical components fail all the time. Are u rooted. Modified anything recently?

No. I haven't touched it at all yet. I am pretty satisfied with the performance so I left it alone. The only thing worth mentioning is that I overheated taking a lot of pictures during an event. Maybe this did a number on it!
I have been discussing the issue with a technican today. It is a hardware issue, you cannot fix it. Apparently, the proximity sensor dies after ~2 years - at least somewhat. Why somewhat?
Check this out: You can check the status of your sensor using MINIOS, type *#546368#*815# (n.b. - swap 815 for your model number).
Now click device test - MT - ok - Individual Item - Sensor test - WAIT!
The proximity sensor will run a test and likely come up with a figure between 60~90. The actual value should be 220+.
Meaning: Your phone thinks it´s ~6-9 cm away from your face, that is not enough to trigger knock-on but it´s far enough to be triggered using the backside button.
My knock on doesn't work, but knock off does. Not a major issue, just annoying!
