has anyone else noticed that when you answer a phone call the screen turns off ...I hate it ...I have to hit the power button to wake the phone up and end the call .. does anyone have a fix for this ? thanks in advance
thats how all phones have been
is this your first smart phone bro?
if u dont cover the sensor it wont shut off
The screen should only turn off when you put it to your face . Once you pull away the phone the screen should wake . Check your settings you shouldn't have to use the power to wake it .

yea I know right lol ....I looked into the settings and haven't seen any controls for that feature
Yea I noticed the same thing. During a call pulled phone away from my face and screen stayed off. I thought something was wrong but if the call is active screen will come back on, if person hangs up and ur not quick to uncover sensor the screen stays off.
do you guys have screen protectors on your phones??? zaggs perhaps??
If anything is "blocking" your sensor, then it assumes that your face is up to the phone. The phone would then only wake up when the call is ended or the power button is pressed.
You must not have ANYTHING covering the sensor
I would say that this is most likely the case
Mine doesnt do that unless I put the phone up to my ear. Normally I just answer the phone and click it to speaker. When I do that the screen stays on....unless my hand/finger happens to be covering the light sensor.
I have Invisible Shield HD. And there's a cutout for the prox. sensor. Have the same problem. Hopefully HTC will fix it on the next firmware update

I'm not so sure about that. My OG Evo has a standard screen protector that "covers" the sensors, and they still work just fine. Maybe those crappy Zagg orange peels will interfere, but I still don't see that being too likely, as they're not really blocking any light.
I have this issue as well and after reading all over for the past two days it appears some units have this issue and some don't. Further complicating the issue is the fact some have screen protectors and some don't. Some have made cutouts on their screen protector and then it works as it should. Very weird.
As soon as I make a call the phone screen goes black while laying on my desk. When the call is over sometimes I can hit the power button to disconnect the call...sometimes I have to hold the power button down 10 seconds to soft reset the phone or I cannot get back to any screen and the call stays connected. Very weird. I got my phone at BB so I am going to stop back and see if they have had any returns and what their thoughts are.

Yeah I wish that was my issue....I don't have a screen protector on my phone and it doesn't work as designed.

I bought a Zagg and had the issue. They left a hole for a sensor but I think that's the light sensor with the proximity sensor being just to the left and covered. It's a small red light that turns on when making a call. So I made the hole bigger by making it a rectangle uncovering the proximity sensor. Now my phone goes on and off like it should when putting it to my ear. Maybe that'll help some of you? Though I have read some people having the issue without screen protectors.

Not sure if this will help or not, but in settings/accessibility settings there is an option to end calls using the power button. Might help.
OK, this is a bit OT so I apologize. But I can't figure it out and really dont feel it warrants a new thread. I hope you dont mind me dropping this in here.
Yesterday, at some point, this icon came into my notification bar and i CANNOT, for the life of me figure out what it is.
It looks kinda like a hearing aid or Bluetooth headset icon. But I use neither. I've looked all thru settings trying to figure it out. Checked thru accessibility . Just stumping me, and making me feel REALLY stupid.
Much thanks to anyone who knows.

I experienced the same issue with the screen turning off as soon as I placed a call. I pulled the Zagg HD off and the issue was resolved. I'm going to best buy today to exchange the Zagg for a new one and I will cut a little notch into it to see if it works.
After the screen goes off you have to press the power button but that little red dot next to the proximity sensor stays on unless you flash a bright light on it. I think regardless the proximity sensor is really sensitive and the Zagg HD just makes it that much more finicky.
Being in a dimly lit area makes it worse too.
**Update**
I went to bestbuy and exchanged my Zagg HD for a new one. I got home notched the cutout for the sensor a little more. Installed it and now I don't have any issues with the screen turning off.

LOL anytime......and no worries we all get stuck at some point.
I've been using my sgs3 with smart stay enabled and noticed it doesn't seem to be sensing me looking at it.. I wear glasses.. and I'm wondering if this is a limitation ?
Sent from my GT-I9300 using Tapatalk 2
I also wear glasses and i find it works fine for me. Remember it doesnt work in low lights.
I Just tested it and it's not working without glasses on either. I see the 'eye' in the notification bar flash after 15 seconds, then it dims the screen, then again 5 seconds later and then screen switches off.
I've had smart stay enabled since day 0 and the phones had a few power cycles/reboots.

Doesn't work for me with my glasses on or off. Must be my face!
doesn't work for me either. not smart
maybe the galaxy just doesn't like your faces?
maybe that's what samsung meant with it being smart. hehe
seriously i have read somewhere it is the face it is tracking not just the eyes.
It even worked when my Dogs were looking at at a few times, and it's annoying because often I put phone off to the side not looking at it and still stays on and wasting battery.
I'm sorry, I didn't realise Samsung required users to look like dogs for this feature to work.
I'm thinking of flashing a custom Rom anyhow.. be interesting to see f it works on another Rom.

Well I do look a bit Ruff.
I just got my Galaxy. Seem to have the same issue, it's not working. Well I think there will be a software update soon enough.
If I consciously blink every so often I'm able to keep the screen on, but if I don't move or blink it turns off - at least that's how it seems to me.
Can't really get it working consistently yet.
I've had my phone since launch and it dimms but never turns off. I wear both glasses and contact lenses.
If the front camera is.nt pointed towards your face it may turn off however which is annoying sonetimes

Hi,
I got smart stay working!
I opened the camera, switched to front facing and positioned the camera so that my face was in the centre of the screen and taking up about 50% of the area.
Now when switching to home screen the little eye kept popping up and going away and the screen stayed on!

I noticed it works flawless. I have it set too 30 seconds.

Great
I find it very useful and works great, I don't wear glasses and I'v only had it two days but does as expected, I can look at it for 10 minutes and it won't turn off, if i point it away from me it turns off after my timeout.
I found if I closed my eyes and squinted one eye a tiny bit open it still didn't turn off though, but it's not like I'm playing hide and seek with it.

Doesn't work for me
when i watch the screen, the screen didn't turn off, -> ok, this is work
but then i closed my eyes about 2 minutes, then when I opened my eyes, the screen didn't turn off
It works for me. I don't wear glasses though.
Correction, it has problems in landscape mode.

I find it is a mixed bag. It rarely turns off when I am looking at it. But on lots of apps the screen dims meaning I have to touch the screen anyway. This rather defeats the point if you ask me!

I'm hoping someone has a solution to this very annoying issue I'm having with my Note 2.
It's Verizon - stock - 4.1.2
When I dial a phone number and put the phone to my ear the screen goes black - as it should. But when I move the phone away from my ear the screen doesn't come back on. It stays blacked out and I can't get it to come back on with the home or even the power button.
This means I can't hang up, I can't put the phone on speakerphone mode, I can't use the touchtone pad to navigate through menus. It's made my phone a real pain in the arse.
Anyone have any thoughts on what to do or what's going wrong?:fingers-crossed:
A couple things I'm thinking... Try pulling out your spen when it happens.. Do a battery pull if nothing else.. It might be the proximity censor... Do you have a screen protector on it?

I'll try the s-pen, maybe that will work.
I've got a screen protector, but it's the same one I've had on since I first bought the phone months ago. I've pulled the battery several time, it's the only way to hang up!
I too think it's the proximity censor, which sucks because I don't want to trade in my phone for some refurb that's gone through God knows what.
Good luck...those were the only things I could think of. ..

Check your case and your screen protector. and clean the proximity sensor. Know it sounds weird, but have problems before with screen protectors getting oil on them when placed to the ear and the sensor thinking you are still close. Also lighting from cases makes the sensor go fruity. Not a science but worth a check.

What I found out is that the timing of the two knocks is less important, what is more important is to keep the finger on the screen after the second knock. After the second knock just keep it on the screen until you see the LED lights up, and you'll see how more efficient it will become.

I noticed most of the time when Knock On fails for me is because the phone isn't on a solid flat surface for example while I'm holding it in my hand or while it's on my bed.
This makes me think the accelermeter is used for this feature. So if you have too much "suspension", it won't trigger.
Just my thoughts!
Edit: I just tested with incredibly light touches and it still worked so perhaps it isn't accelerometer enabled. =S

Great tip
Exactly what i was looking for although still a bit slow compared with what i had with my Nexus 4 and the touch control app. But at least I just do Knock knock once.
That really does work everytime.
Nice tip. I have been playing around with suggestions that I have seen elsewhere but yours seems to be the most consistent (I've done it 25+ times now in a row with your technique). I've even tried changing the rate at which I do the knocks (fast versus slow) and have also tapped on different parts of the screen. It seems like the key is leaving your finger on the screen on the second knock.
Previously some things that I read to increase the success rate were (each with mixed results):
- Always tap on the top of the phone (where the notification bar would be)
- Always tap three times instead of two
- Tap once and then pause slightly and then tap twice
On a side note, does anyone know how this feature works exactly? Is it simply the digitizer detecting the taps on the screen or is there something else going on?
I tried tapping on the back of the phone. This didn't work so the at least use the touchscreen for the knock knock feature.

Ya, after doing some more testing, it must be the touchscreen. The reason I thought it may have been something else is I have gotten it to work by tapping in the top right corner of the phone (presumably not on the screen) but that's probably b/c the bezel is so small. I haven't been able to get it to work along the bottom of the phone (over the LG logo).

I hate it bc that's how I was when the first iPhone came out...made me want to pinch to zoom my laptop screen. Now I find myself tapping the iphone or laptop to unlock but get mad when they don't lol
Knock On feature to turn screen on doesn't work if proximity sensor is covered (try to cover it and tap the screen - it will stay off). Also phone needs a short while to detect the sensor is not covered anymore. So if you pull out your phone out of a pocket and immediately try to turn screen on it simply won't work at first try. Second usually does the job. I've never really had a problem with unlocking the phone while it's on the table or something, when the sensor isn't (or wasn't two seconds ago) covered by anything.
So the reason of our problem is slow response from proximity sensor, it's super fast to detect the sensor is covered, but a lot slower to detect it's uncovered. (You can test it during the phone call - you'll see what I mean).
The solution is just wait a second after you pull out your phone from pocket or after you holding it the way it covers or is near the proximity sensor. I don't think guys triple knocking or keeping your finger on the screen is really helpful. ?
Maybe it can be fixed somehow by our devs, make the proximity sensor reacts quicker.

Probably does that so it won't come on by "knocking" in your pocket. Not a big deal for me at all. And the OP's method is working 100% of the time fur me. No need for 3 knocks any more.
I'd like to confirm what don't others have said and say that the most common mistake is tapping too fast.
Correct that the knock on only uses the sensor to avoid turning the screen on in your pocket.
However, if the touch screen constantly listens for these knocks while it is turned off, shouldn't that consume at least a considerable amount of battery?

This tip however, does not apply to turn off the device. Two quick taps (and release) takes care of that always!

sorry for this really really dumbass question but when u say "After the second knock just keep it on the screen until you see the LED lights up"
i infer 1 knock (tap and lift finger) and then 2nd one is not actually a knock (tap and lift finger) but just tap and keep ur finger there itself
or
is it 2 knocks and then (after second lift of finger) jst touch the screen again
good i really feel like dumbest dumb on this planet asking this question but please do reply
i dont yet have g2 but planning on buying it so i cant confirm myself what u meant
My phone's always-on display will turn off. I can't bring it out of it's 'slumber' anyway other than plugging it in. It instantly pops out of sleep and works fine. I'll lock it and while I can see the always-on display the fingerprint reader will unlock it with no problems. This just started in the past hour for me. I've tried resetting the phone and the issue still pops up, and quickly at that.
Are you using a case or screen protector? Could be something interfering with the ambient light or proximity sensor causing the phone to think it's in your pocket at all times?
Edit:
Actually just tested this. Covered the top sensors and the always on display turned off and fingerprint sensor no longer worked just like you described

You may be right about that. I'm using a lifeproof case and I had just opened it up to clean off the inside (I had shown someone the phone earlier and dog hair found its way to the inside of the case). Funny thing is I turned it completely off and let it sit for a time, as opposed to the restart I did earlier, and it's working alright now. Maybe I just needed to reset it's calibration by resetting it?
Anyone know how to disable this weird dependence on the light sensor? I just don't understand why it would ever disable itself because it's dark.

I read this is a feature of the phone. The always on will turn off in your pocket or in a darkened room. Nice idea since you do not need to be using the juice then. You can test this in a dimmly lit room by cupping your hands over the display to block the light.

Sure, but it won't turn on even when I press the back button. Pretty obnoxious when I'm sitting in a blacked out room and I have to hold it up to the computer screen to activate it.
Yeah, I'm sorry I didn't read the thread carefully. That sucks. I'm in a dark room now watching video. The display turned off, I heard a notification, when I picked up the phone it came on. I do not like that that the led notifications stop. I'm not sure what happens to sound notifications when the always on goes off. I prefer to set the phone silent until a certain time in the AM and then use a sound profile to get notifications and a low volume.

I'm thinking it was the Lifeproof case I have on it. It all worked fine for a week then when I tested the case for waterproof it failed (the phone wasn't in it). I sent for another one and it seems to be working alright now. Maybe it had something to do with the inside of my case getting wet? I don't know.
Great! Enjoy your phone g why are we still calling these things phone?). I like the G5. Now that we have torur I am hoping their for some nice tweaks.
I've had this happen too and it made my life proof case useless because I couldn't use my phone with it on it I still have the issue once in a while but not nearly as often anymore
