I have the VZW gs3, running the stock rom with the motion lift to ear to call enabled. I've noticed that during a call, when you go to input numbers, such as if you are on automated call center, if you try and press the 1 key the screen goes black as soon as your finger gets too close to it. Then comes back when you are a little further away. Not sure about 2 and 3, but the lower keys did not have the same problem.
I thought maybe the phone is attempting to shut the screen off, thinking I'm holding the phone to my face maybe? Either way really annoying problem, has anyone else noticed the same thing? Is there a workaround or fix?

It's because when you're moving your finger to the 1 your hand gets in front of the proximity sensor, which turns off the screen. Just be aware of where the rest of your hand is and it won't happen anymore.
Yes, it's the proximity sensor so watch your other fingers and you go to press a key. I must say this is one of the most annoying things of the SIII I have found so far.
Alright, thanks, is the proximity sensor the two small dots next to the samsung logo?
One of them, yes.

Does that mean I can just bring my finger up to the sensor to make a call when texting? so that I don't have to press my face into the phone?
Hey. Thanks for reading!
I got an s4 recently and have not had any problems with it till now. I had to call a company today, and I thought the problem I had would not reappear. I'm posting here so...
On two calls lately I'v needed to input numbers during the call to give information. When I try to enter the numbers the screen turns off until I move it a little, then it turns on... until it detects my finger about to touch it, then it turns off again. The call continues through all of this. I could barely input the ten or so digit number I needed to provide. This only occurs during calls. Even when dialing my Voicemail I have a struggle to put in the 4 digit pin because the screen acts like a grinch, turning off when I try to press numbers. I turned off all the s4's "eye-monitoring" features and it still does this. Any ideas?
Thanks!
open your dialer
press the menu button
select call settings
uncheck "Autoscreen off during calls"
voila

This will work.. but then it'll produce another problem when your cheek starts to press buttons.. ending in a txt msg to your mom whereas the msg was created with speech to text... while you were talking to your g/f.
Found the option. I may just have to turn it on and off as needed.
Now to find the on screen keyboard sensitivity! Thanks!
I have s similar issue where my screen turns off when I start a call and doesn't come back on wheni pull they phone away from my face. It only comes back on wheni puts power button or home button, but then the screen doesn't turn back off when I put it close to my face again. Turning off auto off feature does what is supposed to but then what's the point of the auto off anyway. Still searching for answers for the last 2 weeks.
There should really be a way of adjusting the sensitivity of this. My wife's S4 just recently started doing this, and my guess is that it's picking up the palm of her hand as her cheek and preventing her from being able to actually press any buttons on the numpad while on a call.

This is exactly what is happening to my two week old gs4. I make a call put it up to my face and the screen turns off correctly. Then when I pull it away from my cheek it stays off. The only way to turn it back on it to hit the power button or home button. It's like the sensitivity of the proximity sensor is off.
I just disabled the thing. Really sucks for my conference calls that I mute and unmute and also use have to key into the calls.

does anyone have an actual solution for this? i've tried like 5 different custom roms trying to fix it without any luck it's so bad now that i can't even hang up anymore.

You guys try using a can of air to blow into the ear piece? Dust gets in there and screws with the proximity sensor. People have fixed it that way. Also if you have a case on try making a call with the case off and see if that happens. Sometimes Even though you wouldn't think it...its too close to the sensor and messes it up. Had that happen to me

I'll try it later today and get back to you on how it worked
Let us know if that works. I've been having this problem as well. However, I feel like it started happening after the last update to VRUEMK2. After that is when I noticed it, although that may just be a coincidence.
Basically no matter if I call someone or answer a call, the second I put it to my face and the screen shuts off(or if I hit the power button) it stays that way forever until the other person hangs up on their end. The screen won't turn back on until they hang up.

My girls sprint s4 was the one doing this and like I said the compressed air thing worked. Poor design if dust can get into the ear piece and mess with a sensor that's not even right next to it. Oh well. Let me know how you guys make out

compressed air works
Just tried the compressed air. It works. I agree that this is stupid.
Huge thank you to whoever mentioned compressed air in this thread. This was driving me nuts at work trying to manage through phone trees or switch calls without being able to get the screen back on. Compressed air was the fix.
THANKS!!!!!
Method 1.
As it happens due to dust so blow Air from ear speaker that will clear the dust from your sensor and solve your prob hopefully.
Method 2 (Root Needed).
go to samsung code *#0*#. then SENSORS and Read your Proximity sensor values.
Calibration is not needed if
your phone doesnt vibrate in normal but does so when u physically put your finger on the Sensor.
Calibration needed if
your phone is vibrating in this menu no matter what, you put your finger on the sensor or not
Follow these steps
1. download Android Terminal from store
2. type these commands to calibrate automatically
$ su
# echo 0 > /sys/devices/virtual/sensors/proximity_sensor/prox_cal
# echo 1 > /sys/devices/virtual/sensors/proximity_sensor/prox_cal
Reboot and see if it works.go to *#0*# and check if it continuously vibrating or only does so when you put your finger on the SENSOR.
I still continuously vibrating even after putting the upper comments use this manual maethod which always works
you need to manually put values in ur /efs/prox_cal.it Reads Hexadecimal value. so you have to convert your decimal values into HEX (which can be done by any online decimal to Hexadecimal converter).
FIND YOUR Decimal Values and pushing them into /efs/prox_cal
Method : finding two values for calibration . offset + normal value.
FINDING OFFSET
cat /sys/devices/virtual/sensors/proximity_sensor/prox_cal
note down the values it returns.. mine is 5,64,100.. you only need the 1st value which is 5.
FINDING NORMAL STATE
cat /sys/devices/virtual/sensors/proximity_sensor/state
note down the value if returns. mine is 64
now ADD OFFSET value + Normal Value
5 + 64 = 69
Convert in Hexadecimal which is 45.
Pushing the value in /efs/prox_cal
# echo -en $'\x45' > /efs/prox_cal (if not working try giving "space" after $ i.e. $ '\x45)
then
# chown system:system /efs/prox_cal
# chmod 644 /efs/prox_cal
# sync
# Reboot
All done. after that go to *#0*# then SENSORS and move your finger on the sensor, yout phone will Vibrate only when you put your finger on the sensors.

Every time I make a call, the screen dims and then blacks out in a matter of seconds. It's in an Otterbox Defender. I have tried every setting I could find and have it set to turn off display after 10 minutes but something is overriding that for this phone app.
I'm new to LG and the V30 but on my last device it detected proximity to the screen during calls so your cheek doesn't mistakenly hang up or something. I believe it uses the front side camera to detect your head there. Could that be what os going on?

Mine does the same and I dont think it's to do with proximity sensor. When i make a call on speakerphone or Bluetooth with nothing near the phone, it still dims and blacks out
I agree it's likely not the proximity sensor in this case as I always have it on a desk and use it via bluetooth but thank you for that suggestion. But, in many cases, I need to enter in several series of #'s for conference lines and changing options but the screen blanks out way too fast. When I double tap it to open the screen, I sometimes accidentally hit a # and have to start over again...

Do you mean it turns pure black, or just dims? Mine dims if I'm on a call utilizing the speaker. Just touch the screen to brighten it up, then type your conference numbers.

I have the exact same problem with my V30. I use Bluetooth, either on a headset or in my car. After a few seconds, the screen dims, and then a few seconds later, it blacks out completely. When it dims, I can tap on it to wake it up, but the screen still responds to the tap, so if I happen to tap where the hangup button is (easy to do in a moving car), I end up hanging up on myself. Or, if I'm navigating through an automated attendant, when I tap the screen to wake it up, it invariably hits a button for a choice I didn't want, and I have to back out or start over. Very frustrating! If the screen goes completely black, then I just hit the power button to turn it back on, but once again, it'll dim out in a few seconds. I would LOVE to have a fix for this! I like this phone better than the past Samsung phones I've had, but the Samsungs don't do this.
I want to add my frustration to this issue as well. I also have a V30 and this happens all the time. My mom has a G6 and says the same as well. It is simply unacceptable. If this is an LG-specific issue and it isn't fixed (or at least given an option to change the screen time-out) then this is a deal-breaker for another LG in the future. (same goes for the glass back as well, but that's another issue...)
Eagerly awaiting a fix or workaround....

I have the same problem on my V30+ since the oreo update. Before it was OK.
During call screen blacks out and then when I take my ear off screen it does not light up again.
I need to press the power button to have the screen displayed again during call. I wonder it this was not done on purpose in order to preserve battery
Nowever It's frustrating because I was not used to this.
Any ideas?
Thanks Anndy
Same frustration for me. I make regular use of speakerphone and it is very irritating.

No fixes yet that I'm aware of. The "solution" I use is to tap or double-tap on the very top of the screen where there are no buttons that will affect the call. But this is by no means an acceptable solution.

I, too, want to add my frustration with this problem. In my case, the screen goes black immediately after touching the phone icon to connect a call. I talked to the T-Mobile people who said they never heard of this before. This has been an issue since 2012, so that was useless. This started happening with the last update. Hopefully if more people complain, a fix will happen.
Same here...

I hope we can get a fix or an option to this soon. It really messes up calls when options are needed during the call.
I've had the exact same problem with my G6 ever since I purchased it (February 2018). It's really annoying and a problem when you are calling an automated voice system and it dims before you can make your selection and double tapping to wake can cause you to hit a wrong number selection (which happened the other day when I was refilling a prescription). Please fix this!
Happens on the V20 also with the latest update from Verizon. The only way around it is to tap in an area you think won't affect the call every few seconds. The number bar on the top seems to work. defintely need a fix for this. Really annoying

Me too! The solution? NONE, NONE, and NONE.
I called T-Mobile today about this very problem after my frustration hit the roof. I complained it's impossible to hold business conference calls on my phone because the dialpad screen dims in exactly 5 seconds. I need it fully lit so I can mute/unmute at-will for clear-sounding and respectful meetings. Yet, as every smartphone user knows, computer screens are no match against sunlight. I inevitably fumble my way around the dialpad on a bright day.
I did every configuration possible to mitigate the problem: Screen Timeout (none), Auto Brightness (off), Brightness (100%), Battery Saver (off). Nothing stopped the dialpad from dimming like usual. However, to my own surprise, all other apps respected my settings during a call. So is the LG phone/dialpad app itself ignoring my system settings? Yes. Yes it is. My theory was soon confirmed....
T-Mobile offered to do a 3-way call with an LG representative. The conclusion? I was told flat out it's a "feature of all LG phones", it's the "default", and there is "no way to change it". SERIOUSLY, LG?!?!? Shame on you, LG!!!! I didn't say that to the LG rep, but, I did tell her I will be "forced stay away from future LG phones" if there really was no solution for this and every other phone LG makes. She offered her scripted apology to me several times but, alas, there was nothing she could do.
PS: This is so, so, so disappointing. They could have kept their default but provided a system option to enable the app's FLAG_KEEP_SCREEN_ON. They could have taken my customer compliant seriously. So, for anyone reading this, if you want to do any active use of the dialpad during a call, stay away from LG phones.

Root, use Google dialer? Does it dim also? I have it installed, I'll check tomorrow morning.
Google dialer "Phone" app doesn't help...nope!
I gave a workaround in an identical thread somewhere else in this forum. Use Waze navigation app during phone calls. The screen won't dim. Drag the phone call thingy over to the Waze screen.
Found it:

If I need to mute, unmute I just click that to go back to call dialer interface for a few seconds. Then I go back to Waze screen to keep display on.
Yes, it's a wonky workaround, but it works. When I use this while driving, I make sure my phone is plugged in for charging -- because the display will stay on for the entire duration of the phone call.

My LG G8X does the same thing, goes dim after a few seconds, then blacks out completely. In the day & age of "press 1 for this, press 2 for that" it really should allow for more time before the phone becomes disfunctionable...
New auto update on LG phone times out too fast
My LG phone auto updated to a 3 sec. screen blackout and can't be changed in any settings menu. The solution is to install the "Keep Screen On Free" app which completely solved the problem and lets you change the time out settings too.
My screen dims rather quickly with the dialer on and then turns off. My default screentime out is 2 mins, but this doesn't apply to the dialer. It gets really annoying if you have to get through a couple of prompts and the screen keeps dimming. Any suggestions on how to address this? Either have the same 2 minute delay apply to the dialer, or even not have it turn off at all.
Thanks!

I got my Mate 20 last week and I have a nagging issue that I am trying to find a solution for. When I am in the car i have my Mate 20 in a cradle. When I make or receive a call the call screen appears, then about a minute later it will turn off (go black). When I touch the screen it will come back on. I have my screen timeout set to a minute so I understand why this may happen. However, the screen time out I don't think should do this when using the phone call app. Is there a way to keep the screen on during a call? I have looked at the settings and found nothing. I am coming from a Blackberry Priv running andriod and there was a setting the allowed to keep screen on during calls.
On my last 4 Android phones (Samsung) I had the same behavior...which I actually liked as it saves battery. There is no setting AFAIK to disable that on M20P, I mean besides extending the screen timeout.
You could use MacroDroid to set a couple of rules: one to increase screen timeout while a call is active and another to change it back when a call ends.
There are also some apps that are supposed to let you keep the screen on while a specified app is running (like Keep Screen) so don't know if that would work.
