Screen flashes on/off during calls - Galaxy Note 4 Q&A, Help & Troubleshooting

I've had two Note 4s, w the first one I could make a call & whenever I pulled my face away from the screen it would turn on & vice versa. That one eventually had hardware damage & I replaced it through AT&T & got a "lightly used" one. It was guaranteed to work as good as new, but this one does not have the same feature. Instead, whenever I place/receive a call, the screen continues to flash on & off no matter what I do. I won't even block the sensor & it flashes. I press home, the power button, adjust settings, try anything - nothing works. It turns on & off when I have to dial addtl #s or use the phone at all. It's making me incredibly upset. I can't/don't want to replace it at this point. Are there any software hacks, or do I have to give up?

If you have xposed, there is a module that you can use to disable the proximity sensor. There may also be some in the play store.

preventing accidental phone dialing

Today I had this problem for the 2nd time. My Qtek 2020 was in my bag and the phone button got pressed, calling my friend for 51:18 minutes!! How do I prevent this from happening?
There are (at a minimum) two ways of doing this.
1. Start -> Settings -> System -> Button Lock -> "Lock all buttons except Power button" -> OK
2. Place the device in a case (I use the Seidio hard plastic XDA case) while not in use to prevent inadvertent button-press.
2 is easiest, but 1 is pretty much guaranteed to work.
the case
I received a leather snap-case with the device. I believe the inadvertent press of the button (or tap of the screen) may have happened while I was using the device (CALENDAR, TASKS, etc.), although I don't know how. I do know that when I press the green talk button to switch over to the phone, it seems very easy to press it twice and redial the previous number.
As for button lock, how does that affect my ability to answer the phone when it rings?
Button lock does not affect your ability to take a phonecall.
The phone turns on when you get a call, then you can simply press the green button.
I am still wondering why button lock is not activted by default...
I've put my phone in my pocket before, and then found it to have powered itself back on almost straight after being powered off. Then, in my pocket alongside the Jabra and the wired hands-free, I get all sorts of wierd scrawled notes & stuff. I had a new Task yesterday, and at one time my Personal Details had a load of gibberish written all over the place.
The Faux-leather thing the XDA2 came with just seems too bulky to me.
Best bet is to power it 'off,' leave it on the side for a minute and power it 'off' again if it wakes up on its own. And, if you leave it in a bag, check for messages/missed calls when you get back. And make sure to turn it off even after a call you don't pick up.

Phone-likeness of TyTN?

Gday TyTN folk.
I have an iMate PDA2k and am thinking of moving to TyTN, but being a bit frustrated with my current unit I'd like to know whether TyTN makes a better phone than BA does.
My specific botherments are:
- notification light (green/red/orange) where the functions over-ride each other. e.g. if I miss a call while its charging, it starts flashing red, but then it completes charging and goes green. Actually, even if it's not charging it seems to stop flashing red after a while. I want it to keep flashing red until I actually handle the device and should have noticed.
To me it makes more sense to combine the bluetooth light with the charge light, and leave the phone notification as a separate item.
- notification icon space in start bar. Currently it's ALWAYS showing a multi-message bubble icon (I'm always in CDMA 1x coverage, and also have an app running that puts its own notification icon up) so I don't see a new one for SMS or voice message. It looks like the best answer might actually be a 3rd party start-bar app, but still.. is it any better under WM5?
- waking up. Incoming calls, messages, and bluetooth connections, wake up the device completely. If it's in the pouch, or worse, in my pocket, the screen then gets bumped, thereby performing actions I don't want to. Even getting it out of my pocket without bumping the screen is a challenge. I tried setting an unlock password (some time ago) but that wasn't satisfactory; I don't remember whether the screen still unlocked on incoming calls, or if unlocking was too much a nuisance.
Ideally, it should wake up enough so that the firm hardware buttons are unlocked but the screen isn't active until you've used a button.
The voice-recording button used to annoy me with accidental presses when removing from pouch; I changed that button to do screen rotate which I find more useful, and no big deal when pushed accidentally - just push it again.
- Sound quality, especially for the person on the other end of a call. I've had people tell me I'm faint on the iMate. Positioning is a little interesting as I don't really want to rub my face all over the screen. Does the TyTN pick up any better?
- turning the phone off. (Like Windows' contradictory "click start to shut down") I really don't like the fiddly actions required to "turn on flight mode" on pda2k, especially when I don't want to get out the stylus. People with normal mobile phones can turn them completely off using one hardware button, and they don't have to look hard to see whether it's on or off. Some have mentioned wanting an easy way to switch to/from silent mode.
Is there a quick, sensible, easy way to turn the phone on and off, preferably also to/from silent?
Thanks

First a corresponding icon (envelope, phone), after more notifications, you get a bubble (?). Not a bubble all the time.

One hardware button for standby, hold it to turn the device off completely. You get a window where you can just hit the d-pad button.
There's also a button for comm-manager, there you can select silent/vibrate mode and flight mode.
Hi, you speak of not wanting to rub your face on the screen, I actually use my TyTN in speaker phone mode to prevent this, I just quickly enable speaker on a call, and flip the phone to where the back is by my face, it puts the speaker in a good spot also, I know it sounds a bit weird, bit works pretty well.
Granted I don't do this with every call, mostly I use it when I know the call is gonna last for more than a few minutes.

You're right about the notification icon, but if I was watching the screen at the time of the additional notify then I'd already know what's there and wouldn't need the icon. On the pda2k cdma, being in a 1x coverage area generates a notification, plus mNotes puts one, so there's a bubble even before I receive any sms, voicemail etc. Combine that with the behaviour of the flashing light, it means if I missed something I may not know about it unless I go looking.
Thanks re the hardware button, that's good news.

Screen Lock issue with HD2

After i hang up on a call (when the phone is in sleep mode and the screen is locked) the screen unlocks. this is quite contrary to what is mentioned in the phone manual chapter 1 page 45. this becomes an issue since i use a bluetooth headset and the phone remains in its sleeve/case and after every call, a whole bunch of applications will launch since the case is in contact with the screen. have i overlooked some settings or are there other owners who have faced this issue?
ideas and suggestions welcomed
did you check it out if any of the hardware buttons being pressed against the case hence wakening up the phone.?
i had it to only closed al my apps in taskm and it stoped flickering
My HD2 is also behaving in the same way even in controlled test conditions - the phone unlocks when a call comes in (I'm presented with slide to accept or reject call) The phone unlocks during the call, but fails to lock again on disconnect (either by pressing "end call" or hang up via bluetooth).
Can anyone verify this? Is it interacting with something I installed?
I believe I found a (complicated) workaround.
What I want: leave HD2 inside pocket, answer calls with bluetooth headset, hang up and phone will go back to lock.
Problem: After I hang up using bluetooth or press the big red "End Call" button or the other party hangs up, the phone stays unlocked! It stays powered on and all kinds of buttons gets clicked.
Practically all lock sw uses their own lock screen (which I don't want to install). CSDevCtrl does not trigger by phone. TouchLockPro uses its own transparent lock screen but can respond to phone events. Using the !SUSPEND for TAPI\Ended under settings does not seem to work when the screen dims about 50 secs into the call.
Solution: Use TouchLockPro together with LockAndOff. Get TAPI\Ended to run LockAndOff will turn phone off, whether by bluetooth, big red "End Call" button, or the other party hangs up.
BTW: I think there is some confusion on whether the phone locks when you
1. press the big red "End Call" button, or
2. the hard "End call" button
in the forums.
I noticed that HD2 have a light sensor next to the top ear speaker.
During a call, if the phone is put near the ear and cover the light sensor , the screen become non-active which is good.
If anyone can come up with a lock sceen using this light sensor , then the problem with random launch of program when phone inside pocket will be solved.
This lock screen should only activated right after an end of call, beacuse , sometime you may want to use the phone in a dark place.

It's the proximity sensor that turns the screen on and off during a call, not the light sensor. How else would it work in the dark? (which it does)

My proximity sensor does not work, when I am getting a call my screen turn off and when I am taking the phone out from my face it turn on only when I am out side at the sun!! the screen stay off when I am inside room. I tested it with flsh light and it is working also.
I have a T-Mobile US version of the HD2. I am having the same problem when using the bluetooth system in my car. After answering or making a call the phone stay unlocked. And then starts making random calls while I am driving!!!!
There has got to be an easy fix for this!!!
Buy pocketshield, problem solved.
i have this unlock problem with 1.48 rom and i solve it by pressing start button and lock. after that everything works fine unless i change theme in settings. then just repeat first step.
Solved
Same trouble with me until I use the following software. I tried it and it's almost perfect. unzip it and just copy to your HD2, run CallerLoc.exe and click Yes, you'll find:when you hang up, or he/she hang up a call, or a call is established, the screen will turn off.
Why say 'almost perfect', the software is in chinese, but the filename is in english. and it's a call location software but with the function we need.
To stop or before you delete the software, run Callerloc.exe and click Yes again.
Hope this will help you. Sorry I don't find a English version of this software. I esure and I'm using this software perfectlly with my Leo.

Same for me
Greetings.
I understand this is quite an old thread I'm digging up but I need a little help as well and I didn't want to start a new topic just for that.
I've this silly problem, appeared right out of the blue:
You all know the standard manila behavior, when the phone is idle, the screen first dims and after some more time, depending on your preferences, the screen locks. It also locks if you press the power off button. This all was happening to me till this morning.
I added an event in the calendar (the only change I made today) and after that, my phone dims and then goes in sleep mode after the designated period of time, but DOESN'T lock!!! It doesn't even lock when I press the power off button. I can still lock it by pressing Start and then lock or by press and hold the power button and choose the lock phone option. So one would say that it's still operational, so why bother about it, but I kinda liked the standard function and I have to freaking idea why it changed!!!
I'd be most appreciative if you could offer some help with that.
Oh, I forgot to mention. Soft reset didn't solve the problem. Erasing the calendar event didn't either.
My phone runs the factory ROM (1.66.482.1 ELL), I haven't changed anything other than user settings (yeah, I'm a noob... )
Thanks in advance!

Pocketshield could be the end of your problems. You can try it for 10 days and see how it goes...
But why do I need to buy third party software in order to revert my phone to it's original operation?
No, this is not the answer I am looking for. I was wondering if you know of any kind of settings that might have changed by accident and caused this undesired behavior.
Thanks.
The best to return to normal operation would be a hard reset. Or you can spend a while trying.
You can try
HKLM\Software\Microsoft\Shell\Lockscreen\Enable=1
HKLM\Software\Microsoft\Shell\Lockscreen\Active=1
Thank you very much. I opted for the hard reset option... I hope it stays ok this time!
My HD2 also had some strange unlocking and unwanted calling.
I noticed it appeared when using the android style lockscreen.
When I changed back to the original one, problem solved
i had this too. the andriod lockscreen seems to be a bit buggy last time i used it, i accidentially called 7 random numbers

while on a call random programs open up

how do i stop this? i'd like the phone to automatically lock or something to prevent this from happening. it appears that first, the screen with all of your apps opens, then my cheek or whatever hits a program. any ideas? thanks
Does this happen when you make a call, or when a call comes in?
If you phone is locked and you get an incoming call, after you answer it remains locked except for the calling options (i.e end call, flash, etc.) but I'm not too sure if you dial out though but ive never had this problem...
this happenes to me too. my cheek will hit the screen and either open things or call someone else while on the phone. It is annoying.
This really should not happen, as the device has a proximity sensor that should turn off the screen when the device is held up to your face. If you make a call with the phone held in your hand and you cover up the top of the phone, say the top 2 inches, with your other hand, does the screen blank? It should. If not, the proximity sensor may be bad and a replacement is in order.

[Q] phone locks during call so I can not hook it

I am using the European Tab, but that probably makes no difference.
For security, I lock the phone automatically after 3 minutes of inaction. This works fine for all apps except phone. Strangely, after dialling (or after picking up a call) the phone first turns off the screen, and briefly thereafter locks the device, within 10 seconds. I can continue the call, but as the screen is off, I can not hang up, unless I first switch it on and enter the password.
I have not found a parameter to influence this behavior. But I know it is not related to the proximity sensor, as the effect happens the same way even when not moving the device from the desk.
Is this a confirmed behavior or does anyone know a cure? It's ok if the screen goes dark, and even if you must turn on via power button, but the password?!
Thanks for any help,
Rolf

It happens to me lately after I flashed a new Rom but I highly doubt that has anything to do with it...it feels like a proximity sensor issue, and a autolock issue as well . I am Clueless sorry
