Screen stays off while on phone call. - G4 Q&A, Help & Troubleshooting

I've noticed when I make a phone call the screen will sometimes stay black and won't come back on. Horrible when the person does not answer and I have to wait for the voice-mail limit to be reached or I have to pull the battery. I recently added tempered glass but I doubt that's what the problem is. Any ideas?

I've also notice that if my screen is off for a while, double tapping the screen won't work but if I press the power button on back then double press the screen it shuts off and if I quickly double tap again screen turns back on. Temper glass the culprit you think? I mean sliding through pages and pressing screen items works perfectly.

I had a same problem started but after i put tempered glass as it block proximity sensor hence you get problem. I removed T.G now it works smoothly.

Don't be too quick to dismiss the tempered glass as the culprit, if it covers the proximity sensors. A lot if people have reported issues like this, if using TG protectors that don't have the cutouts for the sensors, near the front-facing camera.

Someone just told me the knock on feature might be affected by the sensor as well which I didn't think about. The sensor is definitely covered by the glass. Guess I need a new one. Thanks guys.

[Q] Weird Square Mark on Back Button

I am having this weird square mark on my back button that can easily track fingerprint. Let just say my screen is now totally clean without any fingerprints. With the phone turned off, if I started tabbing my thumb on the back button my finger print will be noticeably shown as a square. The size of the square fingerprint mark will be just big enough to cover the light of the button when you turn your phone on. It seems like there is a square portion on top of the back button that are easily tracked with fingerprints. I tried to wipe this particular part with hot moisturized cloth and alcohol but it doesn't seem to work.I do not notice this on the other side, and I am just wandering if any of you having this same problem. If you do, are there any ways to fix this? Thanks Alot!
me too man (but I got on back button, under home button, and next to "back" button !! LOL)...we can't clean. I try everything.
maybe we can remove only by glass polished (but we got gorilla glass so I think it will not work). Also you can put ultra crystal screen protector.
I will try tonight clean with gasoline...if that will not work also....than we can do nothing about it.
I often use my glass cleaning cloth to clean the entire front including the back button and it seems to work great on its own

No its still there.
I have been using alchol to keep wiping it everyday and it seems to lighten it a bit. I also tried blowdrying that particular part and wipe it with alcohol right after. It seems to lighten it a bit but it is still there. I guess we just very lucky -_-

samsung flip cover + smart cover app

works great! open the cover shuts screen off right away and open it turns the screen on. no modification to the cover or phone required!
the app is called smart cover and is in the play store
you mean close* the cover and the screen turns off.
Haha yea. Close the cover shut off the screen

I've been enjoying this app just for a few hours. After a couple of days, I've noticed it consumes a lot and it also provokes annoying issues when I approach a finger to the proximity sensor accidentally. This can happen while playing for example.
It'd be better with a config menu to choose a minimum elapsed time between turning the screen on and off.

[Q] S4 and Conductive stylus on soft "menu"&"back" button

I have:
1) Tmobile S4 (M919) White
2) Galaxy Tabâ„¢ Conductive Stylus ($19.99 now)
3) OEM wireless charger back cover
4) MIME ghost glass version 2
5) Spigen Neo Case
Using finger, the screen and soft button work all the time.
Using Stylus on the screen works all the time.
But there is a problem on "soft button" with "stylus"
1) sometime the stylus works with "soft button", but sometime won't.
2) sometime it works for 15mins or less then stop working on "soft button"
3. in order to have it working again, i have to turn the screen off then on. (but not 100% will bring it back to works)
I also tried with an aftermarket capacitive stylus that it used to works with my ipad 1, the same thing happened.
Do anyone have any idea about this? any physic behind this? thannk you.
The soft buttons aren't meant to be used with a stylus. Unless you have the galaxy note 8, then you are out of luck. The stylus is functional on the screen but not the capacitive buttons..

But how come it does work sometime? 99% of time it will get back to work after the screen off and on?
Works fine for me every time. And I have a 99 cent stylus

have you installed a glass type screen protector on your S4?

Ah, no i haven't. That might be your issue. The stuff on the tip of the stylus might not be strong enough to reach the capacitive buttons as the screen uses a different sensitivity level.

yeah, that's what i thought too. but it does work for few minutes after the screen on, so it's hard to conclude that the issue is solely caused by the screen protector. Maybe the sensitivity level on the "soft botton" is decreasing over time, has more sensitive right after it turned on.

Go into your display settings and check the box next to High touch sensitivity.. see if that helps the sensitivity issue

I tried it, but it makes no difference, maybe it's for the screen only?
But if i am lucky, i can bring it back to works for once if i keep tapping it with 2x more force. what i mean is, it will works on one tap after i tapped it for more then 10 times.
maybe the heat accumulated between the "soft button" and the screen protector is causing the reduction in sensitivity.
anyone has any idea?

screen turns off after I turn it on

I'm having a problem where in low-light areas, my screen turns off a second after I turn it on. The only way I can get it to stay on is by plugging the phone in or unplugging it if it's already plugged in. It seems like there's an issue with the light sensor / proximity sensor that helps keep the device off when it's in your pocket. I'd like to fix, disable, or remove this feature. Anyone else having this issue or know how to fix it? I've encountered it before with the lightflow app where the solution was to remove lightflow, but this is built in which makes it more difficult. Fyi My phone is rooted.
No suggestions for a fix, sorry. I saw behavior like this (screen turning off) when I put mine in an arm band case with clear plastic covering the whole front of the phone. I assume the proximity sensor thought the phone was in a pocket, etc.
The only thing I can think of to simply learn more about the problem is to install CPU-Z and look in the Sensors section to see what the LGE Proximity sensor is reading.
A screen protector that covers the sensors can also cause this.
I get this in low light, too. I have to point it at a light source to get it to turn on. Very aggravating. The longer I use my G4, the more flaws I find.
Do you guys have a tempered glass screen protector on? I have this too, and confirmed this is what it's from. When I had one that didn't directly cover the sensor I had zero issue. It may also be that the sensor isn't that great or polls on too slow of an interval.

Interesting. Does this happen in no-light situations as well? Or is there is a "dead zone" between normal light, and pitch dark?
I tried mine in an almost-fully-dark scenario, in a closet with the door almost fully closed. It turned on normally using both the power button, and double-tapping the screen. Mine is a Verizon model, 610B software.
Thanks @RedOCtobyr for pointing out it could be the screen protector

Yes! I have the tempered glass screen protector. I'm going to remove it now. Besides this whole light sensor issue, I absolutely hate this thing. Compared to a plastic screen protector, I can barely move/drag my finger across the screen because it grips my finger so much. I also feel like it messes up the touch sensitivity so that a lot of lighter touches don't register. Whether that's true or not, the excessive grip this thing has on my fingers and this whole sensor issue is reason enough to tear this piece of crap off.
...
Yep. Light sensor now works in low-light situations but detects when it's being blocked in close proximity. It feels a lot better to touch the screen now as well. Anybody know of a good plastic screen protector to order off Amazon?

I love my tempered glass. Just not ones that cover that silly sensor. I can't say for sure but I feel my G3 glass also covered it without this issue, or at least from what I remember.

how did you over come that issue with the armband. i am having the same problem right now thanks.
Follow steps below to re-calibrate proximity sensor(must with the glass protector is installed and which is sensor covered up)
1. TYPE "277634#*#" in phone dialer. Hidden Menu screen will show up.*
2. Select "Device Test"->"MT", it will show "system will be restarted", then choose OK.*
3. After reboot, GENESIS MiniOS 3.1 screen will show up, press "individual item+power" while power button is pressed.*
4. Next, find "sensor test", enter it(do not block the proximity sensor), the proximity sensor will be automatically calibrated. Then block proximity sensor two times to exit.*
5. Find "Back to the MainList", enter.*
6. Press "Normal boot+power" while power butten is pressed to reboot system, done.
Now the problem should be solved.

Thank you for this. Although on Marshmallow the Hidden menu code has changed. I found this on reddit which helped.
User: Tramagust (I can't link because I have not made enough posts yet )
"It is *#546368#*MODELNUMBER#
So for the international version it is *#546368#*815#
For the Dual sim version it is *#546368#*818#
I assume for the NA version it is *#546368#*811#"
I will see if it makes a difference. Cheers

Yes that code is for lollipop.it is different as you said for marshamallow.

Anyone else having issues with the capacitive buttons?

I checked the Q&A section beforehand to see if anyone else was having similar issues, but didn't see any similar threads.
The Problem:
Sometimes, when pressing the back button (and to a much smaller extent, the home and recent apps) it double taps. For example, pressing back to go back a page in Chrome will result in it going back 2 pages. This double tapping behavior.happens with all the keys, but is most noticeable with the back button due to how often it is used.
Possible Causes:
I suspect that the current screen protector may be causing issues with the buttons. I am fairly certain I have seen this issue before in other devices that used capacitive buttons. I'm currently using a glass screen protector that covers the entire face of the phone. As it stands right now, I value the protection of the screen protector enough to keep it on despite the potential issue it may cause.
It is possible that the buttons themselves are defective, but hopefully that is not the case.
Other Observations:
If I take my finger and slide it onto a certain part of each button, it causes the button to be pressed rapidly without having to lift my finger. Also, I can sometimes overload the buttons, to the point that the backlight of the buttons turns off and they become unresponsive for a few seconds.
The Questions:
Has anyone else noticed similar behaviors with this phone?
Can any users with and without glass screen protectors test out the spazzing button glitch?
Thanks! :good:
I have the same issue with the buttons.
Sometimes, when press any buttons, it detects two or more pulsations.
I have tempered glass screen protector.
I have no protector and do not have this issue.
