I have had my S8 for about 3 months and my previous S7 for 2 years, that have both seen this same fault, so I am posting here to see if
A) Other have seen same
B) If there is a complete solution
C) If there is a workaround
Basically the screen stops responding on the lower third maybe quarter of the screen. I can drag down (such as when scrolling in browser) and the input stops being detected in the 'aforementioned non-responsive zone'.
I experienced this on the S7, thought it was a phone fault and tried to clean it and things like that to no avail.
Since experiencing *identical* problem with my S8 I am convinced it is not simply a HW fault, and i think this for two reasons:
1) I read somewhere someone with a similar issue and advising to run *#2663# and performing the TSP FW UPDATE (GENERNAL). This seems to alleviate it for a short while, as does restarting the phone
2) Restarting the phone causes the pre-boot encryption prompt, to enter my pin. The same zones that are not responsive above are completely fine after the restart.
This leads me to believe this is a SW issue common across certainly the S7 and S8 and I assume both + versions also.
Discuss.
Thanks.

I started a thread before, but found out it could be a software problem as a lot of demo units' compasses don't work all the time.
S4 has this problem too.
I have the N900W8 device, if that makes a difference.

Hi, nicholaschum.
I've the same problem. Mi phone is a N9005 (europe free note 3).
I agree that is a software problem, as if you calibrate the compass sensor (*#0*#) it runs without problem until I restart the phone.
I've also tested several demo units at a samsung store and all of them (galaxy s4, note 3, s4 mini) presented the same problem.
The technical service guy told me that they can change the motherboard of the phone, but I doubt that itgonna fix the problem.
There is a lot of threads, here on XDA, but also in other forums reportinf the same problem on several samsung devices...but unfortunately without solutions.
I'm very pessimistic about this problem, due to that we're more concerned about getting new versions of android instead of get this kind of issues fixed.
Sorry for my english!
Mine's accurate in Smart Tools. DBT N9005 4.4.2 NB7
The calibration does seem to get lost upon a reboot, but you do not have to go into the service menu to recalibrate it.
When you are in google maps, simply rotate your wrist (not your arm). Rotate your wrist around and around about 3-4 times (no need for anything more than this so only takes 5 seconds). And then I find everything works just fine.
You shouldn't have to do that after every reboot, but its not too bad if you realise you don't need to go into the service menu and the right movement to recalibrate it quickly.
I'm running stock android 7.1.1 on a Nexus 6p and there's a dramatic lag in scrolling response. When the screen is scrolling quickly and I put down my finger to stop the scroll there is a huge lag before the scrolling stops. About half a second or more. It seems to occur in all apps (and even system settings menus). I've had this problem since buying the phone a couple weeks ago. It's driving me nuts. I never have this problem with my iPad, MacBook or even my ancient nexus 4. The odd thing is that if instead of just putting down my finger I drag my finger slightly (in any direction) then the lag almost disappears, but obviously that's a very awkward thing to do, especially when none of my other devices require it. Does anybody else have this problem (and hopefully a solution)?
I've talked to Google customer support. They told me to clear the cache of every app (yes that does take quite a while) and to clear the partition cache. This did not resolve the problem and now they want me to do a factory reset, which apparently is the last step before hardware warrantee measures. I'd love to know if this is a common problem.

Hi, I made some tests in your issue doesn't occur on my 6P with stock 7.1.1.

You aren't the only person who has experienced this issue but I haven't had it happen. I don't know if anyone found a solution but if you do a search in this section you should find a thread very similar to yours with a lot of responses. I think some people experienced the issue after updating to 7.1.1

Thanks, I'll have a look. (Tried searching before but didn't find anything.)
For me the problem predates 7.1.1
I found the source of my scroll lag issue. I sometimes enable the magnification gesture in the accessibility settings (because I often use a particular transit app that has insanely small icons). I realized that when I have this setting turned on the scrolling gets laggy. Turning off the magnification gesture seems to solve the problem completely. Not sure if there's any workaround other than disabling the gesture setting.
Hello to everyone,
I am a new forum user even if I follow you by many years.
A few months ago I bought a Axon 7 (A2017G) and since then I've encountered software and hardware issues.
In particular, I upgraded to Nougat (versions 7 and 7.1.1) and I have experiencing loss of data connection and phone line. A simple restart of the terminal has always solved everything.
The fingerprint reader is no longer responsive as before and the camera focus has worsened significantly. I tried to make, several times, a factory reset but it did not do anything.
So I decided to return to marshmallow (B10).
The other problem is display related.
Everything is more clear when using the virtual keyboard. In practice, it is as if the display were disturbed, for a fraction of a second, by a sort of electric discharges. The phone works normally but it were annoying me a lot.
I have already taken steps to replace the device but nothing has changed. Which is your advise except to make a return of the phone?
Sorry for my english.
Just picked up an Android version, touch pad... Is it just mine or are they all wonky like this? Random vibrations, half the time it thinks I'm clicking something, scrolling is just ridiculous.. This can't be how it was designed, is it?
The trackpad shouldn't be behaving like that. I was describing the YB (on MacRumors of all places) and how well it worked but another member complained about the same symptoms that you described. Their issues were resolved by updating to Nougat. I suggest doing that if you haven't already. If the problem persists after that, try a factory reset.
I've just purchased a Tab S5e but appear to be having some issues with the touchscreen. I first noticed it when scrolling, occasionally the scrolling would stop and the device would click on anything that was under my finger. I also noticed this when playing a game where a finger needed to be held on the screen, it was sometimes appear to the game that my finger was removed.
I recorded a video of what i'm experiencing here: https://drive.google.com/file/d/1-33ixSpHRijjhb8g-MNLvbjMvuPRuGrQ. I did not remove my finger at all whilst drawing in white, but gaps appear.
I guess my question is has anyone else experienced this, or could this be a hardware fault? I thinking of returning this and waiting for the S6e or similar rumoured to be out soon.
Thanks all!
I'm experiencing touch screen problems where I sometimes need to tap the display 3 or 4 times before the screen will register the touch. I've only had mine for a few days but Im thinking about returning as well.
I was going through the threads for the first time to see if there were similar issues reported or tips to minimize the issue.
After switching from the Huawei Mate 20 Pro to the Samsung S10+ and from a Huawei tablet to this I have to say I'm seriously underwhelmed with Samsung.

Did you somehow solve the probelm?

Nope. The problem doesn't occur when playing games or using apps that test the display--but does with pretty much everything else. Some apps also have very pronounced jelly effect while scrolling including the Samsung Members App--scrolling through posts has so much jelly effect it makes me feel like I'm going blind.
Earlier Galaxy Tab devices had a calibration setting to adjust touch sensitivity but the type of panel used in the S5e apparently can't be user calibrated. Some people have claimed that the pointer speed setting is the same thing but touch sensitivity and response speed aren't the same thing and increasing that setting to the max didn't improve anything for me. If you want a faster response that's one thing but if the touch doesn't even register in the first place then there isn't anything to speed up.
The game optomizer service running in the background clearly ramps up the kernel when playing games to eliminate or minimize the touch issues and display test apps are treated like games and also get the extra performance boost--but with a locked bootloader I don't think there are any user options besides not purchasing Samsung in the first place.
Would a custom rom solve this?

I always check before buying a tablet to make sure there is developement of custom ROMs in XDA. And the first thing I do when I get one is to root and install one. Are there still "touch problems" with my ROM? Yes and no. I've noticed with this and other tablets that when the tablet first boots, there can be a lag in touch response. But I don't think it has anything to do with "touch sensitivity". I think the problem is that the OS is still "setting up" and just isn't ready to accept touches. (Try it on a Win 10 box. There is a terrific delay between the time the desktop screen first appears and the time it is ready.) This can also be true of apps. The screen can display before the app is ready for input. IMNSHO, I think some people just love to find reasons to knock "the vendor they love to hate".:crying:
Since I bought this tablet, I noticed that issue, the screen detects the touch, but it does not perform the action I want, open an app, select something,etc. I learned to live with it, but that is annoying !!, I installed a Custom ROM specifically [ROM] [UNOFFICIAL] [gts4lvwifi] [10] LineageOS 17.1 and I can confirm that the issue disappears, the problem for which I returned to STOCK, is the cut down quality of Amazon Prime Video, Netflix, because Widevine Level certification . and now in STOCK, I lost Samsung PASS, because it detects that I have the rooted device. fyi, my model is SM-t720.
