[Q] Screen Jittering When Scrolling - Focus General

Hi. I've recently noticed more screen jittering and periodic flickers when I'm scrolling. I tend to keep my thumb on the screen and slowly scroll when I'm reading. The problem isn't as bad if I just tap quickly to scroll, but if I do it slowly, text is shaky or almost shimmering.
Anybody else get this effect when scrolling? Opinions on whether this sounds hardware or software related?

Thanks.

depends if you are talking about the home screen or in applications...regardless it is a software issue.

You didn't mention if you have a microsd card installed and how full it is.
Secondly, this is known to happen immediately after reset, and is somewhat normal.
Background apps might also affect performance.

Touchscreen sensitivity problem?

I've had my elocity for a few months now and use it on a daily basis (with the dextor mod) and it's great except that lately I've noticed that the screen seems to be getting touchier. I mean, if I breath to hard it does false touches. Also, it just appears to do random touches sometimes (activated apps or bringing up menu in apps, etc..) ... it is getting to the point were it is starting to drive me a bit nuts. Anybody else experiencing this?
yeah, i've noticed excessive touch sensitivity at times, but its been off and on. i know having greasey/dirty/sweaty hands/screen causes lots of probs, so a clean screen is highly recommended.
i haven't put a screen protector on mine yet, but i suspect putting one on would give a slightly insulated layer to indirectly lower the touch sensitivity a bit. might be an idea.

OP5 system update now touchscreen issues

I only got the phone today but noticed there was a system update as soon as I got to the home screen after setting it up, now can't help but feel there's some jittery touch latency issues at random, hard to explain but depending on what your scrolling on sometimes screen lag, hardly noticeable I have a good eye for it, anyone else notice this ?

Touch Screen Unresponsive

I don't expect there's much that can be done if the hardware is to blame. This reminds me of my Galaxy S3 -- so it's a problem that everyone else fixed ages ago. When I touch the touchscreen, very very often, it doesn't register that touch at all. Sometimes you get a delayed response. This leads to all kinds of fun where you tap the screen again at the same moment that PH-1 responds to your first touch, so it applies your second tap to whatever is going to come up on the screen a half second later.
Does anyone know if this can be fixed by firmware updates or is this a hardware issue?
same here! my huawei honor 8 is much faster
Touch Screen unresponsive is a hardware issue. I had the same problem with my HTC U11 until it was replaced. Essential phone does not have this issue assuming screen is working properly.
Sent from my Pixel XL using XDA-Developers Legacy app
Touchscreen responsiveness, having to tap more than once for the screen to register a touch and awful light bleed caused me to send it back. But it was from the first batch that were manufactured. No issues on my U11, but I bought it in early August.
Confirming u installed the most recent OTA (NMI64C)? Because that fixed my touch issues.

Yep that's what I currently have. I think the phone found that update on its own a few days ago. Touch issues seem to be hit or miss and maybe less frequent since that update. We'll see how it goes from here.
touch unresposive is due too thermal trottling or like me the launcher stock.
Solved with Evie launcher
Using a different launcher and such didn't help me out, unfortunately. Besides the tap issues, scrolling through a web page in any browser or with apps was extremely slow and laggy. My PH-1 was already being returned, so I couldn't test the latest software update they pushed out. But my device also had some horrible light bleed all along the left and right edges.
No light bleed here. But [email protected], the responsiveness of this touch screen is worse than any other phone I've had. And the new software update hasn't helped at all!...
Same issue!
I too am having touch screen issues. Today, I was on the phone and went to go back to the screen and the screen stays black. I tried everything including pressing the power button and I got no response from the phone whatsoever. The only thing that finally worked was to press the power button and the volume down button and hold them at the same time to shut my phone off after the call already ended. In addition to that issue , I also use Swipe to type and when I do so it often skips over letters and types words that I am not even trying to type . It should be mentioned that I'm a very experienced swipe user and I have not had this problem with my S7 Edge or my Wellington . Also, I should mention that I have the most recent OTA. Also, has anyone else noticed that the camera shutter has a serious delay in it even with the Google camera mod?
I've noticed my touch screen freaking out sometimes. It has more to do with the screen having too many prints on it. Guess it's a bit too sensitive. I wipe the phone screen off and it's fine. Doesn't happen very often. I have one of the latest batches, pure white.
Already looked into this?
Sensitivity:
1. Tap on the "Settings" icon on the home screen.
2. Tap "Language and Input".
3. Scroll to the very bottom of these settings and tap "Pointer Speed".
4. Increase the slider to make the touch screen more sensitive and easier to tap. Decrease the slider to make your touch screen less sensitive and more difficult to tap.
5. Tap "OK" and then experiment with the results.
Essential Support still working on that and they send me this instructions for now.
I think it makes the user experience better.

Same.
Hope it will have a fix soon.
Early on I got the black screen that required a power hold reboot, since moving to Oreo I've not seen that

This I have experienced too
edit : solved with oreo beta
basongwe said:
When I touch some letters on my keyboard, it's unresponsive. Same with some apps. I don't know why this phone is so frustrating to use even if it's a very good smartphone.
EDIT : I'm on Nougat's lastest version, not on Oreo beta.

Had it on both versions to be honest, but hoping it's getting resolved as time goes on!
Just got mine..same thing but...
My screen was doing fine until i installed "All in one gestures". I was messing around with side gestures and this caused the screen to be non-responsive. I un-installed the app, reinstalled it and set it up differently and now it is fine.
I hope this helps.

This helped me. I have mine set at approximately 3/4 and I'm happy one day in. Seems to work great now. I would still like smoother scrolling though. Thanks a million.
I was also having trouble with Android Pay and then found a post about the NFC being located near the bottom of the phone as opposed to the top as on my Nexus 6p.
With these problems fixed I'm completely pleased with this phone.
ugh! Flashed back to stock on 7.1.1/NMJ32F/436 as that is how my phone came, and now I have no touchscreen after re-boot?!?!?! any advice? Please?
Thanks,

Jumpy/Shaky screen while holding finger on my new S8

Hello,
When I scroll down/left/right in my phone and hold my finger on display, the screen automatically shakes left and right or up and down (depending on how I was scrolling my device). This also occurs while charging and while moving an icon on home-screen. I had this issue previously with Asus Zenfone 3, Samsung Galaxy J7 and a HTC Desire (dont remember the exact model though) and a similar issue with iphone 6 (which was registering that my finger was moving on home button). Is this a software problem or hardware problem and how can I fix this ? I have read on web that many people are facing this issue on various phones. but couldnt find any solution yet. Is this my screen sensitivity/touch/display driver/ battery or something else ? If anyone could suggest something, would be really helpful.
Edit: Exactly the same issue as this https://www.youtube.com/watch?v=kxysauxJ5Yk&feature=youtu.be but mine shakes a bit less, still annoys me while playing 8 ball pool and other aiming games like angry birds, etc.
Thanks
There is an app which you can use to test your touch screen by drawing on it. You'll be able to see exactly what it's registering. From what I've seen it happens on a lot of phones with bad digitizers. Try to get a warranty replacement.

Hello,
Sorry for delay. I went to service centre and they said that it is normal because of smooth and silky touch and slight movement of fingers. I explained him that it occurs more while charging and he had to take my phone for inspection.
Here is the correct video : https://youtu.be/PmQ2lra4RXU
My hand didnt have tremors. I agree that human hands are not 100 % stable, however, none of my other phones do it. And if my hand is shaking, then it should shake also while the phone is not charging. When I unplug my device, it stops shaking (almost stops), but when I replug it, it starts to behave weird again when I am holding finger stable. Also, this shaking will move your aim pointer in gaming and it really is annoying while play games with pointer moving.
Is it really normal that your pointer moves while your finger is stable on screen ?

very buggy quick frequently repeated scrolling

Sorry if this was discussed somewhere else, but I couldn't find it.
May be someone could confirm this:
When scrolling frequently one time after another moving your finger repeatedly up or down quickly for vertical scrolling in a long page in chrome for instance, it's very buggy for me.
It has some sort of delay. The screen doesn't react many times.
If the movements are slow and not so frequent, its almost OK. But if you do it quickly it is very bad.
I keep thinking if it is the original Samsung screen protector, I had pre-installed.
It's like that in all apps, I think (Samsung internet, PlayStore, chrome, Samsung store, etc).
Has anybody noticed the same and did removing the screen protector solve this? Or is it something else that anyone found?
Edit: By the way touch sensitivity under settings, screen is enabled.
So try turning off screen sensitivity, are you sure your palm isn't touching the sides also while scrolling?
