HP Touchpad Ghosting Issue? - TouchPad General

I've noticed this for a while (since the minute I turned it on), I noticed there's a slight ghosting issue..

Anyone else have this issue?
Best example of this:
http://gyazo.com/74b225ace1a4ea1c370730a384b29e67
I was scrolling through, and I paused the video. That white ghosting is the issue.

My Droid 3 does this as well. I'm not sure if its caused by the pentile display or if its just software lag. Without HW acceleration in ICS it could be software lag.

[Q] Video frame rate issue

I'm having weird issues with video recording. If I start filming in bright light, the frame rate is abysmal (about 2 fps). In normal room lighting there is no problem and the frame rate is good enough.
The weird part is that if I start recording in the room light and step out side to very bright day light, the frame rate stays good. And if I start in bright light with bad fps it stays bad no matter the lighting.
Anyone else having this issue?
edit: my phone is stock and is running OS version 7.10.7740.16
Hmmm, my phone has the same configuration as yours: Stock rom and everything. I tried what you said, recording from bright light to room & vice versa, but my transitions seem to be smooth with no lags :/ I believe your camera is on it's default settings?
When in camera mode, try panning the camera from bright light to dim & vice versa, see if there are any lags of choppiness in between the transition. If there isn't, there shouldn't be any problems. If there is, I'm not sure what's causing it.
Does anyone here has had this issue as well?
I've tried to do just like you told and I have some example videos but I can't link to them as I'm new member (joined 2008, never written anything before
Couple a days I did some filming outside and I had to start recording by covering the lens with my finger every time to get normal fps. This way it works fine and I get good quality.
I don't know if it has something to do with that there's really bright outside during day because all the snow here but I can also replicate the problem by pointing camera to my monitor.
This is new issue for me too as it was working fine untill now.
btw. It seems to work fine if I use VGA quality.
I just hope I don't have to reset my phone.
Hmmm, I guess no else has had this problem. But this is a really unique one since VGA works, there's no reason why 720p isn't working. Perhaps bringing the phone to the service center might be of help? :/

Hi joaquim! Dont feel lonely, i also have this problem on my mozart phone. I've made a search on youtube, and i also noted that there are several users with the same problem.
I also have another problem, it gets difficult to change from the phone mode to video mode. Every time i press the cam icon to change the mode to video, i hear some clicks inside the phone and the imagem starts to focus. I have to click several times until i can change the mode.
Also, i see no solution for this
your not alone i have this problem too and it happened on my stock rom and even now on the latest custom rom that i installed. I have not tried the finger trick though.
I also tried doing some searching and the only thing i found pointed at possible sd card issues...i have swapped out the deafault 8gb sdcard for a 16gb one and they state that if it is not class 5/6 then it could be too slow writing 720p data.
but like you i have no problem recording 720p indoors just outside or in bright light....
I have noticed that this only occurs in 720p mode, in VGA mode works fine though

Still getting screen flickering issues after the latest update..

So the latest update did correct most of the banding issues but im still having some glitches when doing some things like half the screen will go away for a second them come right back, it does this very randomly. i also noticed this when playing games like shine runner, it will completely lock up. I included a video of what its doing, its weird in the video it would only do it by using the mouse but when doing it on the home screen if the recent apps filled up all the way to the top of the screen it will do it every time whether I use the mouse or touch. I have only had any of the problems since ICS so i know its probably a bug, anyone else having these issues?

here is the issue that it still has with using the front camera, and using the silly faces feature.

I have exactly the same issues.

ok i figured it was a bug, its not too big of an issue but i would like to see it fixed soon.
i have this same problem also. it mostly occurs when i'm using youtube. hope they fix it soon because its annoying!
have the same issue it does it for me as well in Google talk, but YouTube is the worse i get a constant flicker for like 2 seconds.
Same for me too, I think I read that Asus stated it was some of the Prime's hardware drivers having incompadability issues with Ice Cream Sandwich (hence no problems with Honeycomb). Anyhow, I believe they stated that they should have an update to fix the issue in February...hopefully early Feb.!

..same here and only seen with Youtube..
Anybody pinged Gary Key or ASUS about it?
Regards
Ditto, only rarely and seemingly random but I feel it might be after I've just plugged or unplugged the dock.
Similar issue here though it manifests as very thin bands covering only the left 1 inch of the screen and only when scrolling up and down. This is not a constant problem,but not rare either. Shows up in either orientation. I also occasionally get artifacting usually in the form of a momentary white triangle when I use the task switcher button.
Both of these only started occurring after the most recent update: .11 on 1/17. Before that I had never noticed any screen problems.

I have this bug like you... This bug is on ICS. But my bug is like triangle on screen
Just wanted to be added to the list of users having this problem. The longer i have this tablet, the more issues i run into.
Hope a fix comes in the next few weeks, or Amazon get's it back.
Wanted to bump this thread because it seems like an issue some people are having, but it's not widespread enough that it's gathering the attention that the GPS/WiFi/Bluetooth issues are getting.
Personally I'm getting the diagonal screen flicker on the home screen, especially when pressing the recent apps button. Someone noted in a thread somewhere that this is most common when there are a lot of apps stocked up in there. It also seems to happen a lot more frequently when the dock is plugged in, even without touching the recent apps button - it just happens randomly.
Has anyone tried a factory reset to assuage this? That's probably my next step.
Edit: Come to think of it, I didn't notice any screen flickering until I plugged my tablet into the dock for the first time. Can anyone else with this issue confirm they've been using a dock? I might try something like a factory reset with full battery on both dock and tablet, maybe that'll make a difference...input, please, someone
Still having the same issues after todays update...
Ok, so...apparently, when I touch the recent apps button or when I click down on the mousepad, that's when the flicker occurs. When I just touch the touchpad without clicking, the flicker doesn't happen. What the hell? At least that's got me pretty well convinced that it's a software thing.

Before the update everything was fine. No issue at all. It starts for me after the update. Also made my GPS worse. Wifi is the same (they just change the signal icon to look that my connection is full). So far no reboots or lockups.

I have the screen flicker on
1. Youtube
2. When I am using the dolphin live wallpaper (one that came installed stock)
AS of now youtube is still crashing
Im having the same issue. I just bought my prime yesterday and noticed it while running the SKYRIM live wallpaper. I don't have a dock either so i can confidently say that's not the cause to MY problem (can't say for sure about others) and it happens when pressing recent app list or the settings in the bottom right corner.
Not functional threatening but visually annoying. I love the TFP though I have it next to me at work and im ITCHING to just play with the damn thing. We need more atttention to this.
I just started getting a screen flicker about every 10 seconds with a live wallpaper on. They must have "fixed" the problem with the last update.
Anyone found any solutions for this?
looks like the latest update fixed it, will know for sure after i put it through its paces.

screen problem - text is flickering

I have a problem with my gtab. the screen is kind of flockering. Not the problem with the screen flicker when the tab is low on ram, which was solved with the latest kernel. It is some kind of ... grainy effect. I notized first when I read a Pdf file where the background was black and the letters white. The letters were a little bit moving, as if the pixel were not constant. then I notized it is the same in the taskbar when on landscape, but not on portrait. the numbers of the time were grainy. furthermore the letters of the Apps in the Appdrawer, grainy but only in landscape, not portrait.
How can I solve this problem?
rom is Infamous AOKP latest kernel 1.9.1
should be p7510 - p4 wifi

If with grainy you mean that you can see the pixels, that is normal as or device doesn't come with the highest resolution. If it is really moving, that would be odd and is not something I see. Did you check whether it is also present on stock ROM?

I know the screen. I mean not the normal grainy letters coming from low ppi.
The pixels are definitly moving, not all pixel of a letter/number only some of them.
I didnt see something on stock, no.

Perhaps, it is repairable, I already opened the GTab.

Hi,
I am facing the same problem. I watched your videos and its the same.
Did u get it checked. Please let me know if you solve this.
Thanks,
AV
Nothing as of yet.
Tablet can be switched on but lies somewhere around
Now I am on a KK Rom - Omni.
Not suprisingly, the flicker is still there...
push?
Any help?
It looks you have a faulty digitizer and/or screen. Since you tried almost every ROM you can safely rule out a software problem (you did test this with a stock ROM as well, right?). So I'm guessing it's hardware related.

Itsa me again...
My tablet seems to be fine again :good:
What did I do?
Two things:
1)
I left the screen on with power plugged in. Nothing else
I do not know if this did the trick.
2)
I overclocked the tab to 1.4 GHz, activated WiFi Bluetooth, max. brightness and ran a stability test with graphics.
I then wrapped the tablet into a blanket (heat generation).
After 15 minutes I heard the battery (it was charged only to 15 % before)
And it was quite hot.
After cooling the tablet down i read a few PDF and no flicker...
Now I have two tablets, one Asus and one Samsung
Any comment on that procedure?
Unfortunately it is back again.
I burned the tablet again, but nothing. Didnt work this time.
Do you have any suggestions how to fix this?

Jelly effect while scrolling

Has anyone else noticed a slight jelly effect while scrolling quickly on the Tab S3? It is most noticeable in facebook but I can see it in other apps as well. (mails, web pages etc...)
I have had my tablet for about 2 months and only recently started noticing this effect.
The only cnange recently is that my Tab received an update recently. Perhaps it is related?
The S2 had a similar problem.

John.
Yes, just did a slow motion capture to see what is happening
https://youtu.be/7H13L47uhvk
Yes, the effect is as shown in your video. It actually occurs while scrolling slowly and not only when scrolling fast as mentioned in my post above. It also seems that it only occurs in portrait mode.
Strangely, I did not notice this before the last firmware update. It's a very annoying effect and very noticeable. Certainly not something I would expect from an expensive tablet like the Tab S3.

Just editing the link to the youtube video for a higher resolution version.
It happens on all the Tab S range. Even the S1. It seems the S2 and S3 are actually using screens which are native landscape as it only happens in portrait mode on the Tab S.
It's probably due to the high resolution and frame rates of these devices as it doesn't happen on my Tab A with lower resolution screen.
Happens on mine too!

PUBG screen issue on S9+

Why is there a gap between the actual screen & the controls of the game? Any fix? I checked with another friend of mine & same issue persists.
This makes it difficult to switch from other devices as controls are shifted by a considerable margin.

Started getting the same issue from about a month back. Tried quite a few things, but nothing seems to work. Just got used to it.
Still is very annoying though.

When I switch from OnePlus 6 to S9+ it keeps bugging me & affects the gameplay.
No one else?
I thought maybe it's happening to my device only. Can't even find a fix anywhere
That's because you might be frequently changing the display resolution. Keep it in 1080 or 2k and restart the phone

Nope, this isn't the cause. I never manually change resolution and I rarely use power saving.

i have the same problem than i solved the problem with change the resolution of my samsung s9+ from FHD+ to WQHD+ Vice Versa. If your first try is failed, close the pubg and try again to change resolution back to FHD+ or WQHD+. sometimes i try to change the resolution twice than the problem solved sometimes once.
