Bottom line Display flickering

Hi,
im new to this forum
and i´ve one big question that really concerns me.
After two days of using my new XDA Diamond i see a flickering of the bottom line of the windows task list (telephone and programs). This flickering does not occur all the time but normally starts when i use themes with gradient, bright colors like the stock themes installed (Mobile 6.1 and so on).
If i use a theme with only one color this flickering is not observable anymore.
I´ve read some forums for these problems and mainly found them just for the Touch HD.
Is there any way to get around this problem or do i have send it back for repair ?
All and all i´m happy with this phone, so i don´t want to wait for a new one.
But if somebody tells me this is because of defective hardware i would like to have it replaced.
thank you very much for your help

No idea ? Would be nice if someone could answer.
thanks

screen responsiveness problem

Every couple of days I have a problem with the screen becoming VERY unresponsive. It seems to affect the whole screen and requires touching characters on the keyboard, web buttons, app icons, etc. multiple times before the touch is registered. The problem persists until I reboot the device.
I haven't rooted yet or otherwise modded it at all, but maybe I have a poorly optimized app running? Haven't tried to capture a logcat yet either (and frankly wouldn't know what I was looking at).
Has anyone else experienced something like this?
Thanks!

Looks like mine is suffering something similar to the problems discussed in this thread:
http://forum.xda-developers.com/showthread.php?t=1779652

I also have this issue. Was able to reproduce with multi touch tester apps. When I cross axis the touch points freak out. I think it's a grounding issue. If I touch the headphone jack or have headphones in the issue goes away. Called in a RMA request yesterday. Hope this issue isn't present in the next device.

Getting a better look at this multitouch issue, with some good ol' community feedback

Hey guys,
Thought I'd post this here and keep you guys updated on further developments.
I live in the Netherlands and bought a 32GB version at Dixons at the 13th of November 2012
I had found the touchscreen a bit unresponsive sometimes in the past.
But couldn't really find out why it was acting up. I finally isolated the issue.
It is exactly the same as this guys vid:
(Thanks for the vid injahnet)
Together with a little backlight bleeding, I decided to send for repair.
(The problem persisted after a factory reset, no other apps were open when testing.)
I went back to Dixons and showed the problem to the Dixons dude.
He acknowledged there was an issue and sent it for repairs or replacement.
Due to the holidays this can take some time. Maybe even next year
I was about to open my tablet for a look inside one of these days, boy am I glad I didn't do that yet
Anyway to get a good view on this issue globally, are there more people that have the same issue?
You could go to: Settings > Developer options > and then under "Input" you can enable Show touches. and try to to the same procedure as in the vid. (Thanks Peterk-1)
Or you could test with MultiTouchTester like Injahnet.
The weird thing is, my dad's N7 16GB does the same.
Update 17-12-2012: Please do not test while plugged in as the device will be grounded and the issue will not occur. (Thanks dad)
Feedback is really appreciated!
Please vote in the poll above!
Cheers,
Daan

I have zero problems with multitouch while using my Nexus 7. Working just fine, but you must disable any apps which interfere with gestures or it'll steal events.
Can't say I've ever used multitouch with the N7 laying on a random object however.
But sure, send it in for repair......... I'll keep using mine.

If anyone thinks they have multi touch problems then loading an app isn't required. Just go into Developer Options and under Input you have two options to display touch and track detail.

I've done a factory reset before I tested No apps are open except MultiTouchTester
It's in for repairs

Well... Over 200 views. And only 4 votes, which includes mine
Community feedback is failing hard.
Anyway, I'll keep you guys posted on the repaired Nexus.
At the moment of writing we know that three people are having this issue.
I know someone else with a nexus I'll check if he has the issue too.
Cheers,
Daan

Yes, i have this problem. And only while device is laying on the table.

Wow, this is bizarre, thanks for pointing it out. I can confirm it happens when it's laying on my pillow, and doesn't when I'm holding it.

Thanks for the vote guys.
By the way, it seems obvious that the Nexus should not be plugged in while testing.
However I cannot test this 'cause mine is at the shop
Would anyone be willing to test?
I'll add that in the original post (+ a mention of your name and a thank you of course))
Cheers,
Daan

Mine was unplugged while testing.

if the two touch-points got the same X or Y coordinate my nex7 does only detect one of them. i don't think this is an issue.

However, zooming in Google maps for example will become quite difficult

Anyone try and see if taping the ground pin on the wifi antenna fixes the issue? This seams like a grounding problem.

Exactly! I was also thinking of this.
Do people who have this issue also have the flickering issue!?

ecoviws buttress
Just an FYI, I installed CM 10.1 with Trinty Seven. Now I get 10 touches on pretty much any surface.

I don't have a multitouch issue, but I do have an entire band on my screen which has stopped responding to touch at times. It all started when I let my tab shut down due to low battery. Initially, the Nexus 7 neither charged (when put on charging, obviously), nor did it boot up. After trying for several hours, somehow it started charging. And since then, sometimes certain areas of my touchscreen become unresponsive to touch. Since the band which is unresponsive is towards the upper part of the screen, using notifications becomes completely impossible. It keeps 'snapping back up' when I try to pull it down, cos while I am pulling it down, the notification tray encounters an unresponsive area, so it just goes back up. Called up Google and they will be sending a replacement device. All I am afraid about is that I have an 8gb version, and they would be sending an 8gb as well, so I hope it isn't refurbished or something, as Asus has stopped making the 8gig model.

I'm having an issue where the screen, ( mostly in a webpage or document,) starts moving up and down and zooming in and out without my input.

Just tested this out and yes, my device is doing it too. Interesting. No other issues like screen flicker (except the auto brightness bug in 4.2). My n7 is c9O

community feedback is not failing hard, more like you're just starting a new thread without bothering to search if issue/topic already exist.
this isn't new and there is no fix, that is just how the touchscreen function. the N7 isn't the only device to have this.

Don't feed the trolls!
Must... not... feed... aaargh....
You are kinda missing the point of this thread.
It is to see how many people have this issue.
There is no thread capturing that in an easy way unless you want to count every post.
Now please tell your brain to start functioning again and leave this thread alone if you have nothing to add.

Asus Google Nexus 7 32GB touch death zone
Hi DaanJordaan,
Found out that my brand new N7 seems to have a similar "no touch zone" issue; an area the size of my little finger on the left lower part of my screen does not seem to react to touch! It interferes with typing the keyboard in portrait mode (no keyboard problems in up-side-down portrait mode).
When I use the Easylabs Multi Touch test I can see the dot changing color when I move over this area, doesn't happen anywhere else on the screen..
Using the developer tools (turning on the two options that allows to show touch/leave a trail of touch) it becomes even more clear that this area does not react to touch! I can "paint" lines around the "no touch zone" (it actually splits into 2 touch areas using one finger around the "death spot"), and the "no touch zone" reveals itself by not showing any trail/history line of touch..
Oh yes, and it does not matter if I lay the N7 on the table, or hold it in my hand, the issue is always there.
Therefore I returned the N7 back to the MediaMarkt, and they will send it in for repairs...
I've got a bad feeling about this | - )
I am curious to hear about experiences with your N7, once you have it back!
I'll report mine here, in three weeks or so (that's the outlook...).
Cheers!

[Q] htc one screen problem

hi i am in the uk.. on three network. i got my htc one on the 3rd of april, and 4 days later the screen started to flicker? not all the time? but browsing? esp facebook or anything page with white? i guess the white shows up the flicker more? like i say NOT all the time but soo annoying!! not what i expected from a high end phone? Now let me just say i love this phone.. but thought i cant have this.. so i fill out support form for htc and they reply quick advising me it should not do this and to get it changed. i contact three go through the whole call centre thing (like pulling teeth) anyways the upshot was.. three sent me another brand new phone the next day (yesterday) and took back my first one. And guess what? as soon as i switch the phone on, same screen flicker? i treated the first phone like a new born baby didnt drop or bash it 4 days=screen flicker. another new phone as soon as i use it = screen flicker!! i so love this phone but im so gutted!! any suggestions from ANYONE would help.
kind regards
shep

This isn't helpful but you must just be unlucky to have had it happen twice because mine's been perfect and I've not seen anyone else on this forum mention that problem with theirs.
I guess you'll have to get a new one sent out again and hope for the best :thumbup:

Could you make a short video clip to illustrate your problem ?

hi.. to be honest i dont think a video would pick the problem up? you know i could just be being a kill joy? ive watched videos etc and there really isnt a problem with that at all.. in fact the quality of the picture is fab? if i could use an analogy? remember when the volume control on your stereo would get dust in it? and you would have to twiddle the knob to cure it? its a bit like that? like i say it does not do it all the time but i notice it with white in the screen? like facebook google and when i am navigating thru the screens on the phone like settings etc? the white flickers white/slightly darker white? hence my example? now ive changed my text messages colour scheme so that doesnt annoy me now with it.. but obviously as a electronics layman.. i cant help but think if it was a problem with the screen itself, other colours would do the same as they would if there was a loose connestion? and also if it was a power flow problem with the battery? same thing? not just the white on screen? so i can only conclude as a layman again.. that it is some sort of issue with the os? screen refresh rate maybe? i just dont know? and i cant help think stupidly or not that when htc finally get around to an os update to 4.2.2 (or whatever it is) from 4.1.2 the whole thing will be resolved?

Could it be the auto brightness doing its thing? Try turning it off maybe that might solve it.
I might be totally wrong, be great if that fixed it though. Good luck

well well well!!!! And there you have it!! or at least something like that? ive always used the multi widgit for wifi bluetooth brightness etc? so i have brightness preset on that. instead ive gone into display settings, adjusted brightness with slider? no more flicker!! NO MORE FLICKER!! who ever you are!! thank you!!!!!!!!!!

Was this happening when the stock power widget brightness was set to medium?
If so, I have the same flickering ( http://forum.xda-developers.com/showthread.php?t=2243483 ), but I've found out that its not the power widgets fault per se, but the the the level that it sets it to. The widget set the brightness to 33%, and that the level which I'm getting flickering at, regardless of if it was set with the power widget or by the slider. The flickering happens on screen with a good amount of white. Google search result webpage is a good test case; it shows the flickering clearly at 33%. It also seems to depend on where the white is on the screen. For example, I can induce flickering at 40% brightness by moving a light colored icon from the bottom of the screen to the top! Moving it back to the bottom causes the flickering to go away. I can also do it by moving around or resizing the Gmail widget. Flickering happens for me to some extent at brightness values between 33 and 45 under certain screen conditions. Above or below these brightness values, the screen is top notch, no endless flickering at all regardless of how much white is on screen. I'm starting to think this has to do with the dynamic contrast feature of the One. It seems as though it falls in an endless loop of trying to change the contrast, as if it cant decide on what to set the contrast to. Or it could be that the dynamic contrast is fighting for a certain brightness value, but the manually set brightness is not allowing it. I might be wrong about this, and it could just be a hardware backlight problem, regardless, I wish HTC had the Sense (ha ha!) to allow us to disable dynamic contrast if we wanted to. I'm pretty sure this is whats causing the issue where people see flickering when the keyboard pops up.

screen issue?
hi..
i had the widget set on the third setting, the fourth being the brightest. i had the same problem with my first phone and thought at the time it may have been a backlight problem? or power flow problem? i sent that phone back and the next phone did the same? after posting on here.. i removed the widget and manually adjusted the brightness. i like the screen quite bright, manual adjustment cleared the problem for me. i gotta say yep the flicker was more visible on screens with alot of white, google, facebook, texts? and way way annoying! i can only suggest you try the same as i did? perhaps it is just a quirk with the htc? or maybe the os? you never know, when the update to keylime or whatever it is called comes out the flicker may go totally?

JUST had this on facebook? hope it helps?

HTC One Camera problem purple spots

Hello,
So lately when taking pictures in low light conditions I've been noticing purple spots in the right top corner of my pictures.
I did some research and I found a problem with a purple haze but I think this is a different problem.
Here is an example of what I mean:
Picture 1:
http://imgur.com/k3mUpsL,J9p0geX#0
Picture 2:
http://imgur.com/k3mUpsL,J9p0geX#1
As you can see it doesn't matter when or how I take my picture the spots seem to be in the same place.
I have the international version and i'm running Viper One 6.2.1 android version 4.4.2.
Does anyone know what this is and if there is a way to fix it?
Thanks on advanced!

No FIX.
I had same issue with the phone (at&t version). since i was under warranty, at&t replaced me with a Refurb one. Try installing AOSP based rom, or ARHD and see if the issue still persist.

HTC replaces phone with another defective one
I recently discovered my HTC ONE M7 has dead pixels on the top of the screen (notifications bar, which sucks as you cant access any shortucut to the notifications and need to look for the app on your own) and in the middle of the screen (when there is something to click on that spot i have to scroll up or down where the screen actually works. In some cases the page can't be scrolled down or zoomed therefore I am just screwed without options).
Turns out this happens 6 months after I got this phone exchanged by HTC (because the original phone I bought had a defective camera with purple color bug). This means the screen of the "new" phone I got has a life span of 6 months without defects only. SIX MONTHS!!
It seems when HTC replaces your phone for a new one they are just giving you defective products or refurbished products, which will break shortly after.

So nobody knows what is causing this problem and if its hardware or software related?
