If you're using a custom Marshmallow ROM, whether it's Resurrection Remix, Vanir, CandySix, Bliss, Xenon, or any other, and you're experiencing calls being dropped, I think I might have found a solution for you, and it's easier than you think! After hours of downloading, flashing, and testing different ROMs, calling friends and family to test for calls getting dropped, google searching everywhere, etc. I found out that a particular combination of settings might be triggering the phone to drop calls, or as I'll explain in a minute, to hang up.
As it turns out, there are a couple of settings in the new custom ROMs that might cause the problem. The first one is the "Tap to Wake" setting. This nice little feature allows you to turn on the screen by double tapping it. The second setting is the "End Call" by pressing the power button. Thanks to our lovely LG G3 back power button, it's really easy to finish a call by pressing the power button.
Both settings are wonderful and harmless on their own, but when they're combined they will definitely cause problems. Let me explain. You see, when you're making a phone call, once you dial and hold the device near your ear, the proximity sensor detects your face and turns off the screen. This avoids unwanted touchscreen taps (Your ear might accidentally touch the hang up button if the screen was on). However, when the screen is off, your ear still touches the screen multiple times while you talk, your ear becomes like a finger, tapping and double-tapping the screen while you're happily talking to your other half.
Now, normally, this ear-tapping doesn't cause any problems, the screen is off after all, right? Well, bear with me a little longer and you'll see what's going on here.
You might think that when the screen is off, double tapping it sends a "turn on screen" signal to the phone, right? Well, not really. The double tap only simulates a power button press... That wouldn't normally cause any issues, right? But, if you're in the middle of a phone call, what does the power button do? Yes, you guessed it right. It hangs up.
So, that's what's happening, calls are not getting dropped, you are literally hanging up! with your ear!
FIX: Do not have both "Tap to Wake" and "End Call Power Button" enabled. You have to disable one of them.
I really hope this helps a lot of unsuspecting users like me that were concerned about this call dropping issue. Hopefully ROM developers notice this too and help us fix it for real so that we can have both settings enabled.
and so in the sense that i never enabled that to begin with what is the countermeasure?

If you don't have any of those settings enabled, then you're good! If you're still experiencing dropped calls, it might be the modem, or the kernel, the signal, the ROM, it could be anything... that's why I spent hours trying to find the cause of my calls getting dropped... hope you find yours...

Hi Guys,
Ive noticed that sometimes when i use the speakerphone (either by pushing the on-screen button or flipping the phone over), it works fine. However, once the call is over, the touchscreen is deactivated it seems. Nothing works. Cant press anything. As for the hardware buttons, the windows button works, and the power button works. The volume, call, and end call buttons do nothing.
Not sure if this is relevant, but I only notice it if the phone was flipped over (with touchscreen down). If i used speakerphone with the phone facing up, doesnt seem to happen.
The only ways ive found to fix this are to soft reset with that little button under the cover, or to miss a call. (obviously, if a call comes in, I cant answer it as none of the ways you'd use to answer a call still work). After the call is missed though, the touchscreen comes back to life.
any ideas??
thanks
havent notice quite this.. but something similar...
when i wanna make a quick phone call
i open the keyboard type name of contact,
select the contact and hit enter to make the
phone call.. when i close the keyboard to turn
the phone to my ear, half of the screen looks
normal and have of it looks all MESSED UP...
im sure is not a hardware problem or anything.. ( well i hope so )
i think is not bcuz it only do it on that situation..
besides that my screen is normal..
bump
phone been around a while now...maybe someone else noticed this problem...
I've noticed that sometimes my phone will go into "sleep" mode like when you quickly press the power button. Maybe a quick tap of the power button to wake it up will help.
does anyone know of a way or an app to keep the screen off and stay off during a call unless i hit the button to turn the screen on? the proximity sensor sucks and at least once a week i end up muting someone with my cheek without knowing it and it ends up being the 2 of us screaming "CAN YOU HEAR ME?!??! HELLO!??!? HELLO!!??!?!" ... as a matter of fact my girlfriend has it way worse with her g2. her proximity sensor is horrible and she's always putting me on hold, mute or hanging up on them.
my ideal situation (and i will love you forever if you tell me a way or an app to do this) would be if the screen turns off and stays off when on a call, but when you hit the screen on button, it bypasses the lock screen (a totally unnecessary step when you're in a call and would have had to hit a physical button on the top of the phone itself to get the screen on) and turns the screen on, ready to do whatever it is you need to do in the middle of a call.
thanks everyone.
Yeah, hit the power button once and the screen will turn off during your call.

but won't my face going against and away from the sensor eventually make the screen turn back on at some point? i haven't specifically monitored my attempts to try that, but i'm sure i've done it before and it didn't last thru the call. or it did one time and not another or something.
Works for me.

just tried that today and as soon as you take the phone away from your face the screen comes back on (so if you moved it away for a second then back, you've got a phone with a turned on screen right up against your face)
I have the same problem. I do it all the time. Suddenly can't here someone only to realize they are on hold. I'd love some sort of solution or work around as well.

So my DHD seems to not be turning the screen off properly as I hold it against my ear, and for the third time in a week I've just hung up on someone as a result
Firstly, am I holding it wrong? Should it be touching my head?
And if that doesn't work, are there any alternatives (i.e force the screen on or off)?
press the power button to shut down screen display during calls.It happened to me too.
Ah why didn't I think of that?! thank you! That won't affect the call in any way though will it?
You may also try application: Proximity recalibrator.
It is usefull in case proximity sensor doesn't lock screen when you are talking.
I just got my new AT&T S3 a few days ago, and there's a problem I seem to be having with every single phone call I make or receive.
During the call, the screen goes dark, and none of the buttons seem to be able to wake it up again until the other party hangs up. I've literally had to rip my Otterbox off and yank the battery out to hang up during one call to an IVR system that just wouldn't hang up on its own (I guess I could have pressed the right combination of buttons to force a reboot, but at that point I was in no mood to spend 5 minutes experimenting with different permutations of power, vol-, and vol+ to find the magic combo).
Here's what I think might be happening. Note that I haven't exhaustively spent lots of time debugging it yet, on the theory that if it's a common bug, somebody else already has:
Call begins.
Hall Effect sensor triggered by proximity to face. Screen turned off, touchscreen input disabled.
Display settings ticking away in the background force timeout after N seconds. Ignores the fact that the display is already off, and puts the phone to sleep "for real" (at least, the part handling the UI), neglecting to re-enable the power button first.
I'm done with my call. I move the phone away from my face to hang up (or pull up the keypad to enter a selection). Hall Effect sensor broadcasts intent to turn on screen and re-enable touchscreen, and its intent falls on deaf ears because the phone is officially asleep and ignoring it.
Panic. Press power button. Seemingly ignored (though the phone might be waking up enough to see a note telling it to ignore the button, and going back to sleep without further action).
Anger. Press home button. Press volume buttons. Swear violently, and get really mad.
(other party hangs up; lock gets released, phone is awakened and problem seems to go away)
or...
(furiously press various two- and three-finger combinations of power, vol+, vol-, and home until either the call terminates or the phone reboots)
For what it's worth, the same bug show up if I make a call in my car, but the bluetooth call-control button DOES work, even though the phone itself appears to be a darkened unresponsive brick, and triggering a hangup via bluetooth wakes it back up again. I KNOW this isn't due to Tasker or anything, because I've had this problem literally since I made my first call on the new phone to terminate my Sprint account, when it was 100% stock and virgin.
I had the same problem with my white s3 . Then I changed the screen protector and cleansed the proximity sensor with a dust free cloth and haven't had any problems since

Well, I found the root of my problem: the S3's proximity sensor isn't a Hall Effect sensor, it's near-infrared... and the plastic shell on my case is yellow, which meant it was reflecting too much near-infrared light back into the sensor and triggering it continuously from the moment the LED turned on. I ended up blackening the plastic that surrounds the sensor using a Sharpie marker, and it solved the problem.
Samsung S3 won't hang up
I have the same problem and found that I can insert earphones to phone to make light come back on. After looking at this forum I also noticed a setting (which I haven't tried yet). It's the 3rd from last under settings. Settings-Accessibility-Answering/ending calls-The power key ends calls.
I'm hoping that will work.
Just got my Optimus G Pro a week ago, coming from several years of iPhone usage (and upgrades).
As of yet I've not rooted or anything, it's totally stock aside from some play store downloads.
Here's my question. (I don't know if it's by design or if my phone's messed up.)
When on a call, if I hit the lock button, it darks the screen but the phone is not really locked. Any button press takes me straight to the call screen. Is this by design?
The problem I'm running into because of this is; randomly while on a call I'll hear two faint beeps and the screen will turn on. But there is no notifications (no mms, no emails, etc) and I don't have minute minder (plus the beeps are random, not on the minute) so I don't know why the screen is coming back on.
Both of these issues basically means the phone is going to call screen when in my pocket (I use headphones a lot on calls) or on my desk or whatnot and I have accidentally hit buttons.
I'm used to the iphone where when I hit lock, it's really locked. You cannot accidentally activate the phone unless you first unlock the phone. This is a big deal to me because I'm on conference calls a lot. I need to be able to trust when I lock the phone that it's locked (lockscreen).
Outside of calls it works fine, I lock it and I have to do the unlock action to get back to the phone from the lock screen.
Anyone have any insights or suggestions? And is the no lock screen while on a call by design? (cause that'd be a little lame)
I love this phone and really don't want to root (/ custom rom) yet, at least not until I have vetted all the stock issues to make sure custom romming later didn't cause these issues. To me, the lock button should always lock no matter what the phone is doing. It's such a basic expectation that had I rooted or rommed before this I would swear it was cause by that and not a stock function.
The first question yes it does that by design you can hit the home button in call and go back to the.home screen......and if the phone sees light it.thinks its away.from your.face and wakes back up to.do stuff like text or input numbers for call centers and stuff

Hitting the home button while on a call does take me to the home screen, but the phone still doesn't lock. Lock button takes you to a blank screen but the phone is still not locked (at the lock screen).
I believe it's by design, but it sure doesn't make sense. Why would a developer think "Hey, you know that dedicated hardware lock button that all phones have? How about we just not let it work while people are on calls? Why would anyone want to keep their phone from being messed with while on an important call, that'd be silly... Maybe next update we can make the home button randomly take you somewhere other than the home screen."

I don't know but why would you lock a phone during a call? you won't be able to input numbers during a call or just remove it from your year for a second to glance at the call time.....and when the call ends the screen lights up to show you call info and reminding you if you want to lock your phone............so what i am trying to say if i cannot understand the usefulness of locking during call.......if you want the screen to turn off the proximity sensor does that.................can you please give me an example of its use.....thank you
