Flickering/jumping horizontal lines, is my A8 (2018) faulty? - Samsung Galaxy A8 (2018) Questions & Answers

Hi all, I am new here so please bear with me.
Have had the A8 2018 for 3 weeks now, in the past two weeks flickering/jumping horizontal lines started appearing on the lock screen and home screen and it's getting more and more often.
I did my best here to try capture the horizontal flickering/jumping lines, I hope it shows ok: https://www.youtube.com/watch?v=NMroTU85rDQ (*please ignore the diagonal shades, it's just my crap camera)
I seem to remember it only started doing this after a 'system update', which I think is a security patch as it's not got the Oreo update yet.
I've tried wiping cache, factory resetting the phone and turning on the GPU overlay option in developer menu but it's still happening. Is the phone faulty or is anyone else having the same issue?
Any advice will be much appreciated.

yeah i'd replace it

[Q] Swipe back from Magazine to homescreen

I'm going to buy S6 but I would only go for the unlocked/non-carrier version so I'm still waiting. During the time, I try S6/edge several times at Bestbuy and did find something very strange when I swipe the screen left or right. I didn't realize it's the problem(actually I was thinking my finger was too dry) until I tried the S5 right next to it and didn't find anything wrong.
It happens when you swipe left back to Homescreen from magazine app(Flipboard integrated). It's playing animation and don't let you do anything during this animation. So basically if you swipe left twice quickly, it is supposed to go to the second screen on the right but it didn't. That works fine on S5 but not on S6. On S6 the second swipe(or any extra swipe after that but before the animation is over) didn't work and didn't react to your finger until the animation is played completely. I am not sure if it's the problem of display phones or a general problem.
Did anyone find the same problem?
Thx
A general issue, even brought up to attention by several pro-reviewers. Really lame.....

"Ghosts" on the display

Hello everyone, this evening when I play with my s8 plus, i notice that when i swipe from one screen to another, there are "ghosts" goes from top and bottom of the device. The worst it is, when the bringhtness is set to center/low and bluelight sensor is on, ist that normal? I try to make a video and take the screen when I took the password. Phone is after latest update QDD, after I install it, i clear dalvik cache, after that I make factory reset. The phone after the update is little bit slower, and how i remember, befor update the antutu was showing acros 175000, now it is about 172-3000. Where can be problem?
The new video and photo what i take:

What ghosts?
Could you please draw in the picture and Mark the places with the ghosting?
Hello, yesterday I was in Samsung Service center, and they told me, that is normal display functionality. So I was going to the near shop and compare it to another galaxy S8+ and lets see the differences, my display is little bit purple, what i should do, they said I should wait to another update, but last update QDD im currently download and install it and the phone have still a little bit purple colors on some angles. PS: my phone is after QDD update more lagging than before, some ideas what I should do? I made Clear dalvik cache and after that factory reset.
If you are unhappy with a device costing 1k€ then take it back, I certainly would. I am not suggesting you have a lemon but let the retailer see the problem and if you are not satisfied insist on a new mobile. Mine, so far, is fine, zero problems (touch wood). If it misbehaves it will go back as it should.
Let us know how you get on.

Use the red green blue test under *#0*# and check if your problem exists there

I would suggest getting it replaced. However, if you have as much trouble showing them what the issue is as you are us, I doubt they'll swap it. You need to put up some solid color backgrounds and see what it does. The pics you're posting could just be banding in the original image. Not sure what to to tell you.
That's the problem when I try the service code and turn on the red, green, blue screen, everything looks OK. As soon as I go to the main screen or I go to the application menu, and the brightness is set to less than half, the problem is there. This is not a static picture, the "bubble" above moves. When I turn on the blue light sensor, so it's even worse, but if I give more brightness, the problem is not. Also, there is no problem in any application. It would be good to have someone who has s8 plus orchid gray, to check if have the same problem, or at least try setting the orchid gray theme. Anyway, when I compared it with the other s8, the display was more pink, and I did not notice the problem what I have.

I´ve same problem with the "ghost" when i try unlock
Believe me. I cant swe any hosting.
What I see is a dark screen where it should be dark.
I have orchid grey and I can check something for you.
PS. I checked every single picture posted here.
BTW. On yt video the animations are very slow. It looks like you turn on the specific option on the developers setting.

Maybe it is just software, we should wait. But at the night it is really annoying.

OPO touchscreen error, lagged response, only showing piled fragments

Hi all,
Since a couple of days my OPO is doing crazy things on the display. Unfortunately I cannot post here any pics or video.
BUT you can find a video of my screen issue if you search for "OPO touchscreen error, lagged response, only showing piled fragments" on forumsDOToneplusDOTnet
It started out of nowhere, sometimes it goes back to normal and works flawless for some minutes only.
Issue: Touch responses are lagged, it's hard to impossible to navigate on the screen, the display changes constantly showing random fragments of the same piled up.
Has anyone seen something like this before?
Is it rather a hardware or a software issue?
Any suggestions of how to repair it?
Thanks a lot.

Rez Infinite: black screen issue

Anyone else having the problem that only a black screen appears when Rez Infinite is started? The middle indicator for the Daydream is visible, also the "X" on the upper left and the settings gear on the upper right, but nothing else is happening. It doesn't matter how I installed it (Playstore or within Daydream), how I start it. I have tried rebooting, deleting app data from all involved apps, nothing helps. What I haven't tried so far is a factory reset, and downgrading to Android 8.0. In the Playstore there are two reviews which describe the exact same behaviour on the Pixel 2 with Android 8.1.0, so it might be a problem with this constellation. Several other VR apps work fine, I haven't found another VR app that does nothing but a black screen so far (tried a handful).
This is really a bummer, I basically only bought the Daydream for Rez Infinite...
Hi kendong2! Yes, I have the same problem wit Rez. Also happens to me with Darknet and a few other daydream apps. I'm on a Pixel XL though. Also latest official 8.1. And I'm also really looking forward to a fix for this. Anybody else experiencing similar issues? Or maybe someone already has a solution or we can figure it out?
Hello again. I just came back to report that the game is working now. I did a fresh install of Android P DP2 when it came out and decided to give it another shot last night and it worked.

Scrolling problem on android 11

Hello
I have a problem with my f2 pro. After updating to android 11 I got some weird scrolling problem. When I'm scrolling it suddenly stops and I need to take my finger off screen and put it again. I'm attaching video with that problem.
Rebooting phone helps for a while but after a while the problem returns.
My current miui version is: 12.2.4.0(RJKMIXM).
I don't know if it is software problem or maybe hardware issue.
Thanks for your help
deleted.
I have the same problem as you have as. It started after the phone was upgraded android 11. As you said rebooting the phone is solving the problem temporarily, then a few hours later it repeats.
I think it should be software problem, not a hardware problem.
Anyone else have this problem?

I had the same problem, I couldn't even drag and drop icons from one screen to another, it looked like the digitizer "thought" that I removed my finger, reset to factory settings solved it in my case. Setting everything up from the scratch was a pain though...

Hi, i reset the factory settings on saturday. It's solved on that day but today (4 days later) i have the same problem again. I think it should be android 11 problem, it mustn't be hardware problem because it started after android 11. And it's very annoying. I have to restart the phone after i see the problem.

Is it possible that it's one of the apps that you installed causing this?
Did you try to replicate the problem using your phone in safe mode (without third party apps)?
