[Q] Capacitive Back Button Sensitivity

I noticed that the back capacitive button is not as sensitive as the multi-task capacitive button. At first, I thought I wasn't pressing the back button at the right place, but after testing it, it turns out that the bottom of the lit area requires much more pressure before it registers a touch. I compared it against the multi-task button and the Galaxy Note 3. Unfortunately, it appears that my Galaxy Note 4 capacitive back button does not register touches on the bottom half unless more pressure is used. Interestingly, the back capacitive button responds to the slightest stylus touch.
I do have a Spigen screen protector on, but it does not affect the sensitivity of the multi-task button, so I figure it doesn't affect the back button, either.
Is anyone else experiencing this? Thanks in advance.

I dont feel like mines sensitive enough either sometimes.i have to press twice

I thought I was going crazy staring at every press on the back button. I have the same issue. Have to press it more then once. I just used my spen and noticed that the top of the back button above the arrow does not register a touch. The multitasking button does on the top and bottom.

So is this a hardware issue? Should I return phone?

Glad and sad to know that I'm not alone. It looks like a hardware issue to me, but it might be something that affects most of the phones. I'm waiting to see if other people reply to this thread without this issue.
This issue is annoying, but it's not worth exchanging if I receive a unit that's the same, worse, or has a bad screen (I read a review where the reviewer said his unit had dead/stuck pixels near the top, though it could be a review unit concern). I'm going to the Sprint Store to check out the display unit to compare it against mine. If the display unit has a proper back button, then I might consider.

Checked out the display unit and its back button was far more functional. Exchanged mine and the newer one also has a better capacitive back button.

I think I might return mine too. It seems like the top of mine is not very responsive at all. Did you have a glass screen protector on?

Mine is also not as sensitive as I'm use to. Maybe it's meant to be that way though? It's a possibility Samsung did that to reduce the instances of accidental back button presses, but that's just a wild guess.

That makes sense but why don't we have many people complaining about it? Is this a real issue or people are thinking they are not pressing the button correctly.

I'm sorry to hear about that. I had a Spigen Crystal screen protector on, but it did not affect the sensitivity, as the multi-task button worked perfectly. It was definitely a hardware issue solely. I applied another Spigen Crystal to the new phone and there are no issues (it came in a 3-pack).
I don't think many people are complaining about it because it's only affecting a small percentage.

I don't think that it's intended. When I took it back to the Sprint Store, the sales rep tried it out and instantly recognized that it was defective. The display unit and my new unit both have proper sensitivity.

Well, I'm trying to get my unit replaced for a separate issue(screen is green towards the bottom and pink towards the top), so I will report back. Too bad every store in a 30mi radius is sold out.

Put it on "glove" mode ... helped mine

Same Issue Here
I am having the exact same problem with the back button... my struggles with getting it to work properly led me to search for others with the same issue. I'm glad that I am reading that it is not all the devices and that exchanging the Note 4 for a new one may solve the problem, as it did for a previous poster. It is frustrating that the local Verizon store does not have them in stock, and doesn't know when they will... so I guess I'll wait it out - kills the high of getting to play with/setup the new Note 4...:

OK I exchanged mine today will report back. So far it seems a bit better but not by much. Also replaced phone and got one with a gap. Oh well rather gap then a bad back button.

What kind of gap does your new phone have?

I have seen that screen uniformity issue in both the Note 3 and the Note 4. As far as I can tell, every Note 4 is going to have it to some degree. I was pretty upset about it with the Note 3 and exchanged it for one that wasn't as bad. I noticed it on 3 Note 4s, with some being worse than others. I hope you're able to get an improved one!

The gap is around the top left corner. Not bad but the first one I had was pretty much gap free. Doesn't really matter that much cause I have a case that covers it. Out of sight out of mind. So the back button seems to be better with new note. Glad I made the exchange. The only thing is that I lost my glass screen protector. Didn't want to take it off cause it would be useless to me anyways. So I applied a screen protector from my note 2. Works great covered the entire screen. The only thing it doesn't reach to the top. Just something to hold me over until I get some news ones. Also this phone seems to be much quicker than the last one. Could be a placebo effect. I also lucked on a new charger and spen tips. Guy at best buy left charger and tips. I just exchanged phone. :thumbup:

Wiggly unresponsive home buttons

I came across a bunch of threads and videos on YouTube of people saying that their home button is loose, wiggly, and sometimes unresponsive. (as in my case)
My s6 has an issue where it didn't respond to normal pressing on the left side of the button, and since I'm left handed caused a lot of miss clicks for me.
I went to samsung today and they've sent it to the technicians, hopefully I'll get a replacement.
Here's an example from youtube of someone who has an issue on both sides of the button. (only responds in the middle)
https://www.youtube.com/watch?v=R5IIAIl0Dfw
Since this is a manufacturer problem, I think Samsung should recognize this issue and replace units that have that issue.

Yup, had the same with mine, but only left side.
So many quality issues with this phone that I went back to iPhone6.

Mine is on the left side only as well, I'm not sure how the 14 days return policy apply to electronic devices in my country, I didn't even notice the problem at first, now that period has passed anyway so I gave it to Samsung under their warranty, hopefully they'll either fix it or replace the device and won't just claim it's not a real issue or something, it's a premium device that I paid a lot for, there shouldn't be issues like this with a premium phone.

They hand out refurbs under warranty. I would've kept it for something that minor.

I wonder if that's an issue that can be repaired though, like replacing the button or something. (using the manufacturer warranty of course)

Mine has the same issue. Left side presses do nothing until I get towards the centre. Right side is perfect up to the very edge. The button doesn't feel wobbly. But I put it close to my ear and tapping I could then hear the left side is rattling but the right side there's no rattling. I'm going back to the EE shop tomorrow about this. Two things concern me though. Is it possible to get one that doesn't have this issue because many people have said they've had a few replacements with the same problem. Secondly, I hope Oliv3 is wrong and I don't get a refurb replacement.

My first S6 had the exact same problem. I got a replacement with a fully functional home key. Too bad a third of the screen had a really bad case of pink tint. Getting a replacement tomorrow. I wonder what will be wrong with that one...
I am getting a bit fed up with the inconsistent build quality of these phones.

This has ALWAYS been the case with the Galaxy series of phones.
I had 7 replacement S4s, YES 7!!! Because each replacement I got had a fault be it pink tint, green tint, banding on the screen, wobbly power buttons, wobbly home button etc
I finally gave up on my 7th handset and made do with a defective power button as it had a near perfect screen.
So basically, I would rather a wonky home button than half a screen that's pink.
Think twice about sending in for replacement.
My S6 has very unresponsive capacitive buttons, the back button especially doesn't register i've touched it 25% of the time.
But, the screen is good, so I'm living with it.

Refurbished phones like Apple does? So if i send my phone that has a little scratch on the frame i'll get one without it? Because i have the wiggly home button that doesnt respond to clicks on the sides, but i didnt want to send it to repair and be without phone for a couple of weeks, but getting rid of the scratched frame would make me send it.

They repaired it, though it took two repairs.
First time they've replaced everything besides the home button, which was the problem I've sent it in the first place. (They've replaced the entire display, charging port and god knows what else)
Second time they've replaced a bunch of stuff including the home button. (Random stuff like "battery sticker(?)")
Oh well, at least now it responds like it should, it's still a bit wiggly but nothing that bothers me as long as it works well.

Probs they send out refurbished products in the US only, you know to be on the same level of Apple. I think i'll wait then, the problem doesnt bother me that much.

Crooked Home Button?

Currently out of state so I'll try to post photos when I get a chance but does anyone notice their home buttons being ever so slightly crooked? Could just be my OCD but I'm going to hit up Best Buy when I can to compare with the demo models.

Mine looks crooked also.

Not really crooked but the home button on my girlfriends s7e is lower on the left side and won't register when pressed. Some others are reporting this issue and could be related with the crooked issue you're seeing. If it doesn't impact functionality it should be fine but if it doesn't register when pressed sometimes I'd get it exchanged.

Mine is not crooked but the left side and right side do not register as press, you have to hit it dead center and press harder until it clicks.
Just got my 2nd phone in the mail (BOGO offer) and it does the same thing, so hesitant to go in and exchange it for another one that would do the same thing?

Yeah I ended up getting it replaced and the replacement I received today has a loose and very loud home button... Clicks even when you tap it. Tmobile is sending another one. Hopefully third time's a charm.

Loose Home Button?

Received my S7 Edge Black a couple days ago in the UK direct from Samsung online, all great apart from the Home Button feels very loose as in tapping it lifting your finger/thumb off quickly gives a loose feeling and the sound as if it is loose the same as if I shake the device you can here the button moving around slightly. My previous S6, S6 Edge, S6 Edge Plus and S6 Active (I know, I was trying to find the best one and settled funnily enough with the Active!) did not have this issue. It doesn't particularly bother me but does doesn't feel particularly premium because of it and I was just wondering how widespread this this?

Definately sound like a fault. Mine is nice and stiff.

It's not a problem..
Hey,
The Home button will have play in it since its raised and actually depresses into the phone. Other brand have had the same type of button but had the button sunken into the display and was round and convave, so you wouldn't feel it, but most still did wiggle. I have the regular Sammy s7 and the home button moves in the slightest on the left side if I make it move.
I've tried roughly 4-5 stores in the montreal area and every single one did it regardless if it was the regular model or edge. So I wouldn't be concerned about it. If you look at the home button's diagram online, you'll see that the Button's flex cable is to the right side of the button creating less space tolerence. So since there's isn't anything on the left of the button, you'll notice that there is less resistance creating slight movement.
Some phones will have it more than others but you can count on all samsung s7's to eventually have some kind of play/wiggle on the left side of the button. So In my opinion, I wouldn't exchange the phone for this type of issue unless the button didn't register being pressed properly. For example, the s6 was indeed manufactured differently and felt loose when lightly touched or tapped on. So it wouldn't always register presses properly. But thats not the case here and I wouldn't worry about it.
Hope that helps!

Home button issue

Hi
I have my s7 edge for 3 weeks now, and I started to notice that when I press the edges of the home button it sometimes won't register a click.
What I do is just press an edge of the button with my fingernail with low amount of pressure to create this issue.
I can't return it because it's been too long, and I'm afraid to use my warrenty because I'm afraid it won't remain water proof...
What would you do?

I have same thing. It's waterproof. Don't worry about it.

No. This is absolutely not normal. My old device had the issue and I made a video of it and exchanged it. My new one doesn't have the issue.

Mine doesn't have that issue. The "edges" react the same as the middle of the button.

Had this too.... It drove me nuts...its a button shouldn't have to think about pressing it in the middle everytime.... If your still in your grace return period I would exchange it....
I thought I could live with mine but after 2 days I had to return it.... Replacement was perfect...
Edit* Oops noticed you've had it for 3 weeks.... Most companies give you only 14 days...... Guess you may have to just live with it........Is your fingerprint sensor working good?.... The biggest problem I had was I always hold my phone in my left hand then use my thumb to press the home button.... But hitting it on the left part of the button worked 1 out of 5 times.... You'll just have to get used to pressing in the middle

I have the exact same issue with mine, strangely it only became more apparent after about 3 weeks of owning it, meaning I would have to send my device off for repair now; I've decided to live with the issue for now and see how it goes.

Personally I don't think they will say anything.... Samsung quality control has always been a little shady.... Actually this was the first Samsung phone I didn't have to take back since the S2.... But after a couple of days I realized people could barley hear me cause my microphone was I supposed to and out.... Got replacement and everything was perfect ? except the damn home button!.... So one more return later and now I have a perfect screen and a buttons work great
....... I'm really picky and OCD about phones when I get them.... I took my S6 back twice also.... Had a home button rattle and also dust under the screen...... If you ever get sick of it... I use button Savior app.... It replaces all your hardware buttons but you can gesture it or put an onscreen trigger to open it..... I like it better than other onscreen buttons because its always hidden until you need it

Mine does the same thing even when I pressed in the middle. I had to click twice since it didn't register the first one. Happened about 5 times but since I received an update from Tmobile, it doesn't happen anymore, or yet... Hopefully it'll stay that way.

This is something a certified repair center can easily handle without losing the waterproofing. Certified centers have been trained to fix these models, and they have all the tools to do so, while uncertified repair centers won't necessarily have the training, and they won't have the official tools, so they can't guarantee that the waterproofing is still intact after a repair. If an official Samsung rep told you it could be fixed or whatever, then I'm sure it should be fine. You have warranty, and it should be used for things like this.
If you send it in, you'll probably sit where you are now in a week or so with a fully functioning device, or you can just ignore it and still sit where you sit now in a week with a defect device. I would do it.

I would send it in too..... But sometimes it can take 6 weeks... I had to send an S4 in once and it came back almost 2 months later.... If it's something you can't live with send it back..... But you should have a 1 year warranty if anything actually goes wrong with it...... It is a pretty widespread issue in the Galaxy S7 edge line hopefully they get it fixed in later batches.... But if it were me I would probably deal with it rather than send my brand new phone out... Unless they can guarantee you a return date
