[Samsung Galaxy S7 Questions and Answers] goTouch:
I have to confess that it is my second Samsung but never trust them. When I am using the phone I feel like it is going to stop work because of the low quality components. They know how to do all that hype, but I think they deceive us as much as they can.

And here in Brazil it costs $1000. And they use this garbage of touch panel.

Same problem, only it seem to be a problem with certain hands some people cant reproduce the fault on my screen and i can
[Samsung Galaxy S7 Questions and Answers] chriskwarren:
Interesting... Im going to see if this happens to my wife as well. My fingers are pretty dry from doing work, etc... Maybe the engineers and testers at Samsung have soft, delicate fingers and hands unlike the hardworking folks like ourselves ;p

Edit: you might be on to something... Using the touchscreen testing software, I can easily show that about a third of my taps are missed... Wifey tried it and never missed a tap.

Anyone else with this issue care to have someone else try your phone?

Also, I wonder if there is an app that works with our S7 on marshmallow that can increase the sensitivity? There was one called the SGS screen booster that we used on the LG G4 before the touchscreen issues were resolved on the G4... https://play.google.com/store/apps/details?id=br.shop4apps.touchscreenbooster.com
[Samsung Galaxy S7 Questions and Answers] -GK-:
Tried the app but for me there is no difference :rolleyes:
[Samsung Galaxy S7 Questions and Answers] schumi_84:
This is basically my same feeling.

Had 3 units, let some friends try. I had issues and some of them not, less ones yes.

What I really can't understand is why demo units available into big electronics shops are working fine with me as well ?

[Samsung Galaxy S7 Questions and Answers] brane871:
That is strange because the demo units in my country are 930X not 930F and the units sold to customers are F, btw the point is all demo units that ive tested about 10 had the same problem some more some less AND even more important, install Phone INFO app, its green adroid logo...see when its manufactured, mine is 2016.02.18 (probably the first batch) maybe the first series of the phones are defective !

I'm still waiting to hear back from the company i bought my phone from & returned it to.

If they claim they can't reproduce the problem, I will ask them for a refund and settle for paying them $55 restocking fee.

I simply dont want the s7 now. after so many people having this problem, i think the phone is a piece of ****.
[Samsung Galaxy S7 Questions and Answers] schumi_84:
Who of you is having touch issues like me, has the same kind off issues with S7 edge?

[Samsung Galaxy S7 Questions and Answers] May82:
I've been researching the issue. It looks like S6 owners had this same problem and it was fixed with a touchscreen firmware update.

I've tried updating the firmware using the following method but no new firmware has been released yet. Hopefully this will work once new firmware is available:

-In dialer type *#2663#

-TSP firmware update (general)
[Samsung Galaxy S7 Questions and Answers] meat6111:
So i heard back from the company with my phone.

Absolutely raging right now !

I sent them this video - https://youtu.be/MLUi6hFl7c0

And they eventually sent me this - to "show that they test same way" (in your best asian voice) lol - https://www.youtube.com/watch?v=WbeisOWY1i8&authuser=0

What a f**king Joke. It's like they didnt even want to test it properly.

Then they have the balls to come back and say that because the app is third party, its reliability cannot be trusted (and copy an email from samsung saying the same)

so essentially, the built in software (which cant test this way) is the only software they trust.

DO NOT BUY FROM BEXECTECH !!!!

Same issue here with 2 different devices (onyx black). They were bought from different shops and both where produced in April, so they weren't first batches. First one had AUT CSC code and second one has XEH.
[Samsung Galaxy S7 Questions and Answers] chriskwarren:
Something worth investigating;

I am using the Spigen Crystal PET screen protector. Been using these for years, where a glass one is not suitable.

I decided to replace my protector as I had a few scratches in it already, and I was wondering if this issue could be exasperated by a protector in my case.

I had the protector on, and I was missing the odd tap as shown in this thread. I took the protector off, and I never missed a tap (and believe me, I tried). I put a new protector on, and sure enough, the issue returned.

I am not blaming the protector here, as this is a high-quality, very thin protector, and the issue is only in the bottom-right of the screen. A bad protector should cause the issue in various areas I believe. The screen should work with a well-known, quality protector.

What my experience here tells me:

- If you are thinking of putting this through warranty, you should make sure that you try it without a protector first before returning or sending in. Samsung/vendors will try it without the protector, so you should verify how bad the issue is without protector before sending back.

- Some people here have duplicated this in-store, no protector. This suggests that different screens have different tolerances. Mine seems to work no protector, while another device might not.

- Some people might be able to correct the issue with a different brand protector. I personally am waiting for a good glass protector to become available. Maybe this will help my situation, or make it worse. I think we should keep track of the protectors we do use, perhaps there is a type/brand, etc that can alleviate this for us.
[Samsung Galaxy S7 Questions and Answers] vdanasto:
Truth is that I had a Nillkin Tempered glass on the screen which made the problem quite worse, so I decided to remove it. The problem is still there, but not to such a great extent. Some taps are still missed when typing.

I find it unacceptable though, that a flagship phone of 2016 has reduced touch sensitivity when used with a screen protector. It should not happen, my S4 and S5 had stellar touch screens with no such issues, they registered even the softest touch without error.

Such serious issues greatly reduce everyday user experience.
[Samsung Galaxy S7 Questions and Answers] schumi_84:
Totally agree

Inviato dal mio SM-G920F utilizzando Tapatalk
[Samsung Galaxy S7 Questions and Answers] chriskwarren:
Agree 100%. I'm not making an excuse for Samsung, a flagship device should work great with a screen protector.

But I'm hopeful that software can fix this, and in the meantime perhaps there is a way to cope for now. Also, very important to try your screen without a protector before sending it in or returning it.
[Samsung Galaxy S7 Questions and Answers] goTouch:
I have never used a protector. And the issue clearly exists.

But as I said before, it is odd missing a few types near P, Enter and Space bar (using SwiftKey).

I love this phone, great battery after disabling almost everything from Samsung, great camera and very fast. But we obviously have a problem here that Samsung will never do something about it.

The point is, how many touch manufacturer did Samsung use to build and which one is the defect one and how to identify.
[Samsung Galaxy S7 Questions and Answers] meat6111:
So i got my refund from becextech. (reminder: dont ever buy from them) It cost me a $55 restocking fee.

And now I'm reluctant to even upgrade to the S7 because I don't want to run into the same crap again.

Did everyone with this issue buy online ? or did some of you buy direct from store ?
[Samsung Galaxy S7 Questions and Answers] goTouch:
I am from Brazil and did not buy at a Samsung store. But I think it it doesn't matter
[Samsung Galaxy S7 Questions and Answers] May82:
My wife and I both got ours in-store at T-Mobile.
[Samsung Galaxy S7 Questions and Answers] meat6111:
hmm.

so perhaps it's just the build of the phone rather than where we have all bought them >?
[Samsung Galaxy S7 Questions and Answers] vdanasto:
Seems to be so.

I took the phone back to the shop I bought it from, since I was under the DOA period. The owner sent it to Samsung Service to have it checked, but the service center claims there was no fault found. What is infuriating is that I showed the problem at the shop when I delivered the phone. I asked them to send it back to be rechecked. I am so disappointed by this whole mess.
[Samsung Galaxy S7 Questions and Answers] raj_p:
For me the issue becomes worse when putting the phone on a table and then test. Testing it in my hand makes it difficult to reproduce the fault.
[Samsung Galaxy S7 Questions and Answers] schumi_84:
Did anyone of you try if the same issue is existing with S7 edge? After the 3rd faulty S7 I was wondering if Samsung will never fix that and if upgrade to S7 edge.

Hi, I'm from Argentina , and I have the same problem, in the lower right corner , I have problems with the letter P and sometimes with the letter L , and backspace , my device is 930F, if I write slowly the problem seems to be less frequent . I have placed the film that came with my device , and with or without it keeps happening
[Samsung Galaxy S7 Questions and Answers] humblehyper:
This is exactly what is happening on mine too, I have a United Arab Emirate 930F unlocked that I bought from Amazon. So frustrating. I hope it's a software issue.
[Samsung Galaxy S7 Questions and Answers] NicoKlius:
you tried to return to the factory firmware ? before the OTA? I remember that with it , I had no problems , I think , I'm not sure.:cowboy::cyclops:

I discovered something

Hi !!! again... :P

I discovered something when I turn on my device the first few minutes after turning on , I have no problems with the touch screen , but after a few minutes, about 5 to 10 minutes, the problem appears. If I restart my device , the problem disappears again for a short time.

I have S7 ITV and the touchscreen has the same horrible problem. I wait for the next update of the FW and then take him into care.
[Samsung Galaxy S7 Questions and Answers] goTouch:
Anyone else?
[Samsung Galaxy S7 Questions and Answers] chriskwarren:
About the same for me. Misses about 1 in 10 taps for me if I keep track right now, both before and after a reboot.

That said, I switched to a new screen protector earlier this week and I don't seem to have as many issues. I was using a spigen crystal protector, and now I am using the crystal curved HD plastic. Last time I tried testing tapping down in that area of my screen I would sometimes miss a series of taps in succession... Now it's just one tap here and there (but I have not played around enough to determine if it really is any better... The screen could. Just be behaving better today).
[Samsung Galaxy S7 Questions and Answers] alisaGrg:
From what you guys are sayin I think only US versions are having this issue mostly. Global version here, does have have some display issue but not touch screen issues.

I tried the same with S7 but I couldn't have any improvement. Maybe a new touch firmware was not released yet, or worst case it was a hardware related issue

Hi.. Did you confirm that it was a hardware issue?

I'm having the same issue with my s7

is there a chance that the is a software issue and will be corrected with a firmware update in the near future

Is this an issue with all s7s?

I just tried the TSW firmware update

Will let u guys know if the issue is still there in a few days.

It is very disturbing that a phone of this caliber has such issues.

I checked and updated my G930F today with what looks like the H6 update. No difference whatsoever, problem remains. I've also updated the fw using the dialer code, and cleared TouchWiz data. The "a" button on my Greek keyboard (tiny bit to the left of the UK "a") does not register oftentimes.

Phone's under warranty but this thread doesn't keep my hopes

EDIT:

Using a touch screen tester it looks like the problem occurs waaay more during multitouch. Don't know if this makes any difference

[Samsung Galaxy S7 Questions and Answers] goTouch:
Just received H9 update and the release notes did not mention anything about LCD, touch screen or anything related to it.

But since the update, I've been trying to reproduce the problem trying to find the blind spots and for my surprise I did not find anything. The touchscreen is perfect and I can feel it is more sensitive.

Before the update I could reproduce the problem very easy! Now it is perfect.

The update here in my region (Brazil - ZTO) was about 170MB. Samsung Cloud was introduced.
[Samsung Galaxy S7 Questions and Answers] shotgun10ga:
Is this update already in Canada?

As always with Android updates (especially those on Samsung, and especially those on Bell again..) never hold your breath waiting for an update, as it will only breed disappointment, leading to despair, and possibly even a serious case of existential angst/nausea.

[Samsung Galaxy S7 Questions and Answers] Gabiann1992:
I've also reported this problem, I noticed however that removing the glass protection the defect is almost gone, I emphasize "almost" because I think in those particular areas of the screen there is actually less sensitive than others. Personally after removing the protection it becomes difficult to notice the defect, unless you are looking specifically to reproduce it. I must also add that I tried two universal glass protections and both have been a marked improvement in the sensitivity and response of the touch than the first one I used.

[Samsung Galaxy S7 Questions and Answers] Monrad:
Problem also persists on HJ update. I'm beginning to believe it's a hardware issue. I've already tested 4 devices and all of them have the same problem. You can test it using YAMTT (download it from Play Store). Using 2 fingers, slide vertically on the edges of the screen and your digitizer will start to act funny. Sometimes it won't register your fingers at all.
[Samsung Galaxy S7 Questions and Answers] madermike:
Your suggested test is EXACTLY what happened when I tried the yamtt app (maybe a month ago).

This is so wierd, some people claiming the H6 update fixed their problems, now you say there is no hope even for HJ...
