Touch issues (only in corners), worse without navbar - w/ video!

hey guys,
the videos and the title speak for themself. rest of the screen is fine touch-wise, perhaps with a slight limitation at the left and right edge. since the latter could be software related, do you think that touch registration issues in a particular area (like left and right bottom corner) can be anything else than hardware.
https://youtu.be/Yy5xoOXfm8s
https://youtu.be/d6q90SkSFYc
its getting even more massive, when disabling the navigation bar with custom navigation bar from the playstore (root required). see here:
https://youtu.be/kyVwnlnNeFY
what do u guys think? anyone having the same issues? perhaps someone could test with root and no navbar?
contemplating on just rma-ing or going with a full return (and my old n6p) to wait out the issues and a potential hardware revision.
thanks everybody!

I've noticed a bit of this as well. I believe this is an issue recognized by Google and has something to do with software implementation to reduce ghost touches from the curved screen. If I recall, this was supposed to be addressed in the December security patch update. I'll see if I can find a source for this info.

This is the exact same problem I had with the essential phone. Mine doesn't have this problem.

The touch response is much better on the new 8.1 beta 2.

This is good to know. I figure I'd ride it out until after the December security patch and/or 8.1 is released to determine if I need to RMA. It hasn't much interfered with my use with the exception of gaming on a couple of occasions.

yea going that route too. since then there would also be some time for quality control to be more efficient since i dont think i would have much luck with a new replacement device right now.
but an argument against the software related explanation would be, that some arent experiencing these touch screen issues. would a software update which adresses the issue for the owners with issues then provoke issues for those who havent had any at all since then?

Both good points. I am almost past my 14 day return period, but I have no intentions of returning the device. If I do RMA, I would like to wait a little while so Google/LG can get some of this nonsense sorted out with later batches.

Had the same issue on my device, but running newest december build (9.0). have an exchange from Google on the way. The chat agent also said something about software, so I assume it didnt make it into the 9.0 december update.
Hopefully my replacement device does not have the same issue.

Touch screen issues

I've had Honor 7x for about a week now and I love the phone. I experience no lags or any other issues except one. Touch screen sometimes acts up and is not responsive and sometimes I have to touch the same spot like two or three times to get it to work and it's so frustrating.
The only way that I'm able to make it work well as it should again is by restarting the phone, and then it's all good until next day or so.
Have you guys noticed the same symptom?

May I Ask....

Short Answer For Me.. No.
Are you still within your return period ? Swap it out for a new one.. and see if it's any better.
If Not... Sell It.

Didnt have any issue as such..
Get it checked..

I am having the same issue now I believe. Phone worked great for about two weeks then started having screen issues. I have to push a little harder and slower than normal or touches don't want to register. The buttons along the bottom and the pull down menu at the top of the screen seem especially bad. A reboot clears it right up for a time. I'm past the return period so I have to send it in for a warranty repair. Were you able to get the issue resolved with your phone? I'm a little worried with it being a sort of intermittent issue they won't be able to reproduce the issue and won't fix it.

Yes it is buggy !

Hi,
Yes, I'm also facing the same issue and thinking that removing the tempered glass may help.
Also, there are lags and lack of responsiveness in this device time to time and I don't feel it as a Hardware issue. Its just that if you are not used to clearing out apps from recents, unlike 90 percent of the other users and if you ever felt the phone's hardware/software competent enough to handle those by itself and at the same time, maintaining the performance, then you are wrong.
Now after a good 2 months of usage, I can say that we will have to wait for a slim pure AOSP rom for this device to please us. Its not at all a balanced device and indeed its a total flop. I feel no joy( and sometimes want to throw it on the wall also) in using it now because of these 3 issues :
1. Time to time lag/hanging - due to not clearing recents frequently - Since I do not believe it is really required for a phone with 4GB ram and Kirin, equal to SD 652 processor. My OP2/ Mi Max and all others used to be much much better than this piece of sh**.
2. Touch not snappy and feels like less responsive for a fast user. May be perfectly fine for the one's using it in a relaxed way.
3. Notification quick reply screen timeout because of not recognising it as an active function.
- From a quite unhappy first time honor user !

I got in touch with customer service and they advised me to factory reset it.
After that phone actually felt better with no issues.
However, I was still within the 15 day return window and I didn't want to take the chance, I sent it back and bought another one.
With the new phone all I can say is that I love the phone. No touch screen issues, no lag what so ever, it is extremely fast and even after I cranked it up with apps it didn't get any slower. I can say that it's faster than my broken Nexus 6p.
Love it

Glad you got a new one sadly I missed my return window. I tried a factory reset and only installed a podcast app different from the one I normally use and actually Uninstaller a few factory apps like Facebook, Instagram and couple Google apps docs and sheets. Still had the issue after some use. Always seems to happen after 20-30 minutes of phone calls. I have contacted support and will most likely be sending it in. I'm getting the b140 update as I type this and the change log says "Performance optimization changes has been included in the current software" so maybe that will fix it. What are the odds. Is it hardware is it software I don't know but I would think if it were hardware a reboot wouldn't make the issue go away for a while but that's probably flawed logic. Also I'm using the US variant (L24) 32gb/3gb.

I was having a touch issue, but changed in the settings-Smart assistance-touch disable mode (un toggled it)

Well it's been a couple of days since I received the b140 update and so far my screen hasn't acted up. I'm not 100% sure it's fixed but so far so good.

This seems to have resolved my issue also. Thanks for the tip!
Since it seems software related, and I imagine this 'feature' is to detect whether you 'meant' to touch the screen or not, it would make sense that this is potentially the problem. In my case especially, I would describe the issue as it seems like my screen falls asleep if I take too long between interactions.
Edit: this actually didn't resolve the issue

Unfortunately after further testing the issue persists. Most noticeable in clash of clans, Facebook, Snapchat, other slightly higher resource usage apps.

Still digging in on this, I enabled Show Taps from the developer options and the malfunctioning taps actually do show up when they occur. I sent an email to support 2 days ago with no response yet. Will probably have to call I guess. womp.

got my phone more than 15 days ago, issue started becoming more prevalent this past week. notably when i'm playing rhythm games (lol). thought ir was the tempered glass screen protector but its now happening with a film/wet application protector. i can't replicate it consistently either. would be interested in updates, this is really frustrating.

I still haven't received an email response, however if you go to the site via mobile you are presented with a live chat option during their business hours (listed on the site https://www.hihonor.com/us/support/index.html). I used that to arrange the repair return for the phone. They don't simply replace it which is kind of frustrating, so I guess it's back to my trusty nexus 5 for a week or two. ?
-tg

i've done some looking around -- i know this thread is much older than the recent UI update, but it looks like the most recent update has messed up the touch sensitivity completely. loads of people are complaining on the hihonor forum. hoping this'll be something they can fix with a patch.
really hoping that i won't have to send it in, this is a replacement for my old phone since the charge port was completely shot. so i'd have to buy a new phone anyway...
thanks for the update, hope this all gets fixed soon!

This appears to be related to the most recent update. That is when it started becoming more of an obvious issue.

Oreo will fix this surely... I had same but now its fixed ?

Touch sensitivity
I'm having the same issue, my screen touch is not sensitive I used to have moto g4 it's been a couple of yrs since I bought it even that screen touch sensitivity is better than this. But overall features camera screen everything is good except the touch sensitivity, I need to click everything a couple of times to respond and even while texting I'm missing out some letters. BTW I won't use any screen guard or tampered glass and it's been a week since I'm using honor 7x.Apart from the screen sensitivity issue I'm damn satisfied with the product.
Thanks,
Aditya

I can also confirm that this is a software issue and is resolved by the Oreo update (currently beta, link below), at least for my case of ghost taps registering on different parts of the screen than what I am actually touching. I've been running Oreo for a week now and this is definitely the phone I was hoping for when I bought it :good: I've been emailing details regarding this issue with a member of their beta support team and it has been relayed to development. Hopefully they can/will release a hotfix for nougat in the meantime.
Oreo is currently in beta. The forum post regarding beta enrollment :
https://forum.xda-developers.com/honor-7x/how-to/how-to-beta-test-emui-8-0-oreo-based-t3757323

I used to have similar problems, particularly when I try to scroll by sliding it would actually open the link if there is one where I first touched. Also writing was difficult on SwiftKey, it would jump over and behaved as if I hit enter.
I joined oreo beta and upgraded yesterday, all these problems seem to have disappeared. Fingers crossed, will wait and see a few more days.

Ghost Quick Scrolls, 8.1 issue?

Hi all,
I have recently been noticing ghost scrolls, where I would be slowly scrolling downwards, say, in the XDA app or reddit app, and randomly it would scroll quickly upwards when I lift my fingers. I was thinking this was a hardware issue so I got a replacement device on the way. However, I saw this https://www.reddit.com/r/GooglePixel/comments/7rczu2/scrolling_up_when_scrolling_down/.
Has anyone else been experiencing the same thing? I posted a vid and pic https://imgur.com/a/ny8fT. The second pic is touch input trace enabled in developer options, you can see there was a ghost long fast drag down to the bottom below the navbar.
Have been away from XDA for a while, please let me know if I am going against any rules about posting images hosted on other sites.

I wonder if something like this is what causes Twitter to randomly show me a different tweet when I tap on one. (maybe it's doing a phantom scroll briefly).

yep, thats happened to me a few times before as well. Not twitter specifically, but in reddit I would click on a post, and somehow I would end up on some random other post like 2 post below it, and if I hit back once, I get to the post I originally intended to click on instead of the subreddit list.
So there must be some sort of ghost touches/scrolls on finger release, causing the unintended post to be queued up just before the intended one.
I'm surprised there hasn't been more people bringing up this issue (assuming this is indeed a software 8.1 issue and not an isolated issue in the touch panel).

Reddit has done that to me too, come to think of it.
Agreed that it's surprising we aren't hearing more of this. Makes me wonder if I should do a warranty swap.

Yea, I have a replacement device on the way, but after hearing a few others experiencing the same issue, I'm starting to think it might not be a hardware issue after all.

definitely doesnt sound like a hardware issue.. ive experienced this on more devices than the p2xl and more so on stock.. u also might get it when ur data lags..
on the available custom roms i cant say i remember the last time it occurred.. either way, it cant be that bad to even remotely consider replacing it

Oh really? Have you only experienced this on 8.1 only, or also 8.0? I had the pixel 2 xl back in October/November on 8.0 and didn't experience any of this. I just repurchased the 2 xl several days ago and immediately noticed it within the first few hours of playing around with it.
I think it definitely is a software bug, if not a hardware issue. The touch input trace shows a ghost drag of a perfectly straight line to the bottom of the touch panel with an incredibly high Yv, I got one as high as 179. Normal hard flick scrolling would top out at around 30 or 40, so definitely something fishy going on here, whether it's software or hardware.
It happens for me like between 5 and 10 times within half an hour to an hour, and they are usually annoying enough where I lose my place where I was scrolling.

prolly 8.1.. i got mine around december late nov. pretty sure its software related.. they had an issue with touch on the lockscreen right?

It seems like so many touch issues with 8.1 release. For this reason, I am still using 8.0.

Any update with the replacement device? I am having the same sporadic ghost scroll: I'll be scrolling down a page on reddit or slickdeals app (happens with other apps as well), and randomly it'll perform a strong up-scroll... I notice it more often when I lay in bed on my side, and have the screen orientation locked to portrait, resting the phone on the bed horizontally...

Replacement device has the same issue, so this is definitely a software bug. Hopefully Google fixes it soon in the next patch update.

Nexus 6P here. I started getting these ghost touches with the last security update. 8.1 is the problem, not a solution.

My mom has the same issue of touch on places she doesn't touch, on Pixel XL.
Could it be the same?
Here is a video about it that I took, just by scrolling in the settings screen:
https://drive.google.com/file/d/1JCsTuMDvMNHh0CO7sF7yoLFT26uNIhUp/
It's a bit hard to reproduce, but it occurs eventually.
Has anyone tried to use Android P, and see if it helps?
Anyway, I've reported about this here too:
https://forum.xda-developers.com/pi...h-pixel-xl-t3807188/post76879468#post76879468

Any fixes yet?
I know this is old, but I wanted to know if anyone found a fix for this. I eventually found an Oreo 8.1 Rom that I like and this is the only issue that's bothering me.

Samsung A70 screen touch delay

Anyone here experiencing a sensitivity issue on samsung A70?
I had mine like few weeks ago and notice there is a lag on screen sensitivity. I used to play games (call of duty mobile and PUBG) on this phone and it is lag whenever i tried to make a minimum/fine tune movement. It is annoying and almost useless to play.
I believed to those who are using this phone for photo editing or painting or drawing will experience the same thing.
I compare with my samsung S9+ and note3, they works perfectly. No issue at all.
I also did a test with other demo set A70 phone in samsung store, they appears to have the same problem.
Not much info i can get from the net as for now.
I did report to samsung service center in Malaysia, unfortunately they said i'm the only one who is complaining about this matter. They ask me to check if there is a firmware update in future.
Please share your experience with me.
Please help.
Thanks

Same problem here, was looking all over the internet to find someone who experienced the same issue.
Just for the record, I have also switched on the 'Touch Sensitivity' option in the settings.

I've got this issue too. I've talked to Samsung about it through Samsung members app, and they told me to take the device to Samsung customer center, but they told me that there's nothing wrong with the device. I kept bugging them about it on Samsung members app until they told me that they're gonna pass the feedback to the team.
My advice would be that we all write them feedbacks about this issue, that way they'll listen to us. Also it's important to tell them that you don't have any screen protectors on, cause they're gonna put the blame on it.

I've also posted about this issue a couple of times here and there, on Samsung's Reddit and Twitter also. And I was trying to get some YouTubers attention to this issue so they can talk about it and get Samsung to listen, but YouTubers don't respond to me.

I am tired enough to contact samsung. I even did email their ceo through samsung email. No news from them yet.
Anyway, do you think it is a hardware problem or software problem? Or that is best performance a70 can do?

I am pretty sure this is a software issue. Because Snapdragon 675 should have no problem with this considering my sisters’s old Lenovo P2, with the Snapdragon 625, is perfectly fine.

Definitely software issue. The touch used to be worse but they fixed it, and now it's like this. Also, if it was a hardware issue they would've noticed it when I gave my phone to them to scan it.

I just came back from samsung service center. They told me it is like this due to screen type.. S9 and note3 having a better screen quality. So for A70 screen type there is a limitation of the delay.
I really dont agree with them but this is what they told me. I insist to have a report on this and ask them to highlight this issue to higher samsung representative. But i forgot to take the report number. Grrr...
Imo, this issue wouldnt solve unless you able to talk to someone who is 'working in a software department' and able to explain to them correctly.
And i guess they only take a very good care on their flagship model. S and Note.

That's not the case, they just don't wanna talk about it so that's their way of shutting you out.
I've just updated my phone to September security patch and I can see they're fixing the issue. It's not 100% fixed, but I feel like it's 99% fixed. The touch is better, but not the best. I compared it to my A50 and it's indeed closer than ever to being like it, regarding the touch response latency.
I'm gonna send them a message again to tell them that they're on the right path but it just needs a little bit more fixing. The sooner we report it, the sooner it is fixed.
+ No, most of their phones have great screens, I've been with Samsung for a decade now and I can tell from experience. It's just that this device has a software issue because they're so busy making new phones and giving updates to the A50.

I updated the phone manually through Odin. I used the Israeli version since it's right next to Jordan where I live. The touch has improved, but it still needs some work. The fingerprint scanner has also been improved, it's faster now.

Tell them about this thread so they know it's a widespread issue.

Have you tried increasing the mouse pointer speed in the input settings? I bumped mine up a bit and it helped a little bit but it doesn't solve the problem of hitting a small target not being registered as a touch unless you zoom in. My old phone, LCD was able to hit small targets.

Anyone here experiencing a sensitivity issue on samsung A70?
I had mine like few weeks ago and notice there is a lag on screen sensitivity. I used to play games (call of duty mobile and PUBG) on this phone and it is lag whenever i tried to make a minimum/fine tune movement. It is annoying and almost useless to play.
I believed to those who are using this phone for photo editing or painting or drawing will experience the same thing.
I compare with my samsung S9+ and note3, they works perfectly. No issue at all.
I also did a test with other demo set A70 phone in samsung store, they appears to have the same problem.
Not much info i can get from the net as for now.
I did report to samsung service center in Malaysia, unfortunately they said i'm the only one who is complaining about this matter. They ask me to check if there is a firmware update in future.
Please share your experience with me.
Please help.
Thanks

same problem here bro???

Question Touch screen issue: scrolling happens when I release my finger from the screen?

Could you guys please test something out for me on your S21 FE phones? In Chrome (or any web browser) try scrolling up or down slowly, then hold your finger still and release it from the screen. Your goal is to avoid scrolling the page at all when you release your finger.
For me, the screen often scrolls when I release my finger. My phone seems to be detecting subtle movements in my finger as I release it from the screen, and incorrectly interpreting that as a scroll action. I'm starting to worry that this is a software bug. Is anyone else experiencing this?

I have the same problem, but it kind of started after the protective glass sticker.

I dont have this issue. Scrolling is working fine even with a tempered glass

You are right. The same thing happens to mine, when I lift the finger slowly, the phone scrolls erratically. I said it before in another post but I absolutely know that thie S21 FE does not have the same snappy, scrolling speed that I had on my S21 Ultra. It is a 120hz display, no doubt about it, but something is making it seem laggy or erratic sometimes.

Yeah, I have the same behavior on mine, but I thought that's normal, that's how Samsung One UI manages the scroll. Never had a Samsung until s21 FE, came from a OnePlus 7T.
Still, what's the problem with this behavior? Why does it bother you?

I dont have this issue. Scrolling is normal for me.

do you have any updates on this? I have the same issue.

None. I'm guessing Samsung might of used the same manufacturing process as on the S20 FE (which had the ghost touch issues) and in order to fix it they made some software modifications to the screen sensitivity. So it might be the panel is flawed or purposefully made to feel less flaghsip to make us buy the ultra ) I'm rambling I know, but in this day and age, I think these companies can do such things. I vividly remember not having any display issues on the S21 Ultra and I remember holding both the S21 Ultra and the S21 FE and scrolling up and down. OneUi felt so right and fluent on the Ultra, I have no idea why. On the FE, even when I am typing words I often have spelling errors and typing feels very uncertain and laggy.

I've made a screen recording in 60 fps using scrcpy and the touch debugging enabled while viewing a grid paper PDF.
You can clearly see on many swipes where there is a random 1 or 2 sample points extra when the finger lifts off. It seems to be mostly triggered when trying to do precise movements, like trying to align the grid to the edge.

It's great that we have proof regarding the touchscreen, however I am not sure what we can do to solve it. You could show it to samsung support but I doubt they will recall every single unit and fix it if it's a hardware issue.

I wrote to Samsung support, but they didn’t give me a clear answer, they said that this is a feature of the phone. I think you need to write a lot to Samsung support so that they fix it with an update

That's exactly what they do all over the world. I think they know very well what they are doing. Why bother with defects that only a small percent of people actually perceive. I find this to be really annoying and frustrating. I have no idea what to do to get through them. They do the same thing with the HDR function too. It's always on, you can clearly see it in action after every photo but they'd rather send you to the service center than admitting they know about it and that it is something they did on purpose. Most probably they are going to brush it off and hope people forget about it while new phones will take over the attention of the customers.

I dont have this "feature".... S21FE snapdragon Czechia 6/128

I just got my s21 FE and I'm having this issue. It's annoying. As a scroll webpages, the page hops up after I lift my finger. It's been happening all day. I really hope attention could be brought to this and that it's fixed in an update.

Are you on June update? I'm trying to reproduce it on June update but I can't, it seems to be fixed.

I just got the June update a few minutes ago. In these few minutes of use, I *seem* not to be having the touchscreen issues anymore. But I'll update if that changes. Thanks.

Can anyone else confirm? I am trying very hard not to update the S21 FE from the stock ROM unless it's actually worth it )
