Back light on capacitive keys. - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

Just picked up my note 4 two days ago and the first thing I noticed was the only key with backlight is the back key. Is this normal?
Sorry if this has been discussed, I was unable to find a thread on it.

That's a defect. Go back and swap it out.

Not normal.

Thought so. Thanks.

[Q] Search Button Pushing Itself

Has anyone else experienced the search button pushing itself? I can be touching no where near the search button, or not touching the screen at all, and I will feel the haptic feedback and the button will light up, and screen witl go to quick search.
Anyone have any ideas?
I have the same issue. Not sure why.
yup i seem to have this issue as well, doesn't happen too often though.
Thanks for posting this. I thought I was crazy when I would notice the quick search screen pop up, not thinking I had hit the button. I figured maybe I was grazing it en route to one of the other buttons.
I had the same problem with mine. I thought it was something I was doing, maybe an app, and then suspected the Body Glove case... maybe it was too tight. None of the above. Finally replaced with my 3rd and current Captivate (8/2 build), and it has been rock solid (other than the GPS).
Yeah, it drives me crazy. I think I am going to return my phone today. i have to see what they will do for me since I am outside the 30 days. Then it is time to reflash back to stock...
I had a similar issue and was able to fix it myself. See this thread: http://forum.xda-developers.com/showthread.php?t=767666

[Q] Back button backlight not working?

I have a brand new Lumia 920, and I note that the backlight of the "back" button rarelly turns on....home and search backlight works fine, but the back button only turns on once or twice a day.
Is this normal? how to fix it?
Sorry for my english.
All the backlights should come on together. Sounds like you may have gotten a faulty model; warranty replacement should be no trouble. These things happen, especially when the problem is intermittent and may have slipped through testing.

Capacitive button worries

So on Monday I went out and got a shiny new Turbo. I'm loving it so far and hoping for root and or bootloader unlock eventually. This morning though something odd happened. For a period of about ten seconds my capacitive buttons quit working completely - no vibrate when I touched them, no nothing. The phone wasn't frozen or anything. Then they suddenly started working again. About five minutes later it did it again, but it hasn't done it since. Should I be worried? What should I do?
I'm having the exact same issue, seems to be random.
Ok I have the Moto Maxx and noticed that too... then I figured that in my case it happened because I was touching the screen with my palm while tying to reach for the capacitive buttons. The buttons stop working while you are touching the screen. Check if that is what is happening to you.

I've even had it do that if there is any liquid on the screen...like maybe a few small drops of water after you just washed your hands or something like that.
Does the proximity sensor disable the buttons? Thinking that if the phone thinks it is near your face for a call, it might shut off the screen and buttons to prevent accidental presses.

They will automatically dim and turn off when in a well lit area/room. If you are in a dark environment they will always be on.
Just hold the device under a lamp and watch buttons dim slowly off. Turn lamp off or go to a dark room and watch them illuminate back to life after 8-10 seconds.
Pretty standard, however, if they are going on and off constantly in the dark, than most likely a defective unit.

I'm pretty sure this is what happened to me, after playing around with it I noticed my phone does the same thing. That's a load off my chest, I was a bit worried about it. thanks!
Screen pinning vs Long press for menu
Just a note, I recently discovered that if you have lollipop screen pinning enabled under the security settings and also the "Use long press for menu" setting enabled under display settings, they seem to conflict and cause all kinds of key lag with any of the capacitive keys. Must be because both utilize a long press of the recents/overview key. As long as you only enable one or the other it should be fine. Just thought I'd throw that out there.
I have had this problem too, it simply has to do with the fact that the screen is and capacitive keys are combined. You can use one or other, but not both. If you encounter this, just mess around on the screen for a few seconds and the keys should work again.
Clear cache. That usually fixed the problem for me.

Anyone else note 4 recent and back touch keys flicker?

Just got my replacement note 4,not sure if old one did this,but when after having screen asleep when hitting power or home button to wake screen up the touch keys will sometime lightly blink once before coming completely on with screen,doesn't do it every time,it's a bit random,wondering if anyone else see's this flicker?
To test if you turn off touch key duration completely in display settings,and then turn screen off and back on u can see the touch keys still ever so slightly light up,at least on mine,just trying to figure out if normal or not.

It's really faint can't see in normal light,have to be in dark.
Really?Noone?
Yes, I see this on mine. And it doesn't really bother me.
Ok lol as long as I'm not alone
Mine do as well. Hadn't noticed it until I read this thread. Also, I couldn't really tell until I covered tje the screen and just focused on the touch keys.

I didn't notice till I was up late a few nights ago and all the lights was off.

touch screen sensitivity?

Anyone having touchscreen sensitivity issues? I'm having ghost swipes galore while trying to scroll up and down a page like Google now or Facebook. Try swiping left and right on the home screen. On mine it just started to not respond anymore after a couple of times. Even if I go to the multitasking page, I'll try and swept away each open app and it'll just start to not register. This is while not plugged in btw. I really love the phone otherwise and want to keep it but I'll have to return it if this is a common problem. Is this an issue with the phone or just me? If it is just mine then I'll just exchange it and hope I get a better one.
Actually it is much more prevalent while charging. I also forgot my Moto mod battery pack charges constantly and my cause grounding issues also. Let me know if it's just my phone y'all!
I had these issues initially, especially with the bottom of the screen and the back button, but after a couple reboots they're totally gone. Try a hard restart (hold the power button until it restarts). I use a turbopower mod so i don't think its that.
My charging cord doesn't work.I just bought 3 days ago and it will not turbo charge

after reboot initially it's better but then it returns after a few minutes. is it the same for you? does it return? anyone else having this problem because I'm trying to determine whether I should take this back or not and get it exchanged.
Problem was an isolated incident and I'm happy to announce that I exchanged the faulty phone for another and this one shares none of the problems said above. So in short, if you're having screen sensitivity problems, send/take your phone back for a new one.
It's flawless now! I freakin love this phone!
