Problem "screen pixel" - Nexus 5 Q&A, Help & Troubleshooting

Hi everybody,
I've Nexus 5 with original rom Android Lollipop 5.01
I've a strange problem and I'd like to know if it is a software or hardware problem.
Sometimes, and only with Facebook app, in a part of the screen appear few pixels and they disappeared when I close the app or I move between tab.
Enclosed an example, I reproduce it in photoshop.
Any idea?
Thank you very much.
Ciao!

Its probably a damaged flex cable. Cheap to replace.

Tky for reply. This appears only on Facebook app, and sometimes.
If cable is damage I think always I had this problem.
And if the problem is the app? It's possible?

Not really sure if it only happens in Facebook then.
I'd say ignore it a bit for now, but if it happens more and in other apps then replace it.

Ok tky very much.
Latest question, is there a way to test this problem? For example by a benchmark app or other?

Don't think so, no. Unless you know which exact colors in which exact pixels are causing the issue, which is pretty impossible.

This is a bug in Lollipop and has nothing to do with a hardware defect. I get this in several other apps as well. A fix from Google is already on the way and will be released with a next update of Android.

It shouldn't be any hardware bugs at the start when buying a expensive phone like this.
I have this on my phone too, just took it out of the box...dang this post, I was looking for it from the start.
Are people waiting on this in hopes it's a software/refresh glitch, or exchanging their phone?
I don't have a T-mobile store here in town, just a stand at the mall How do I convince them to stare at the screen long enough to notice it?

It could be a software bug too.

I dont have the details..but there must be possibilities since it has something to do with the color panels or such. Again, it didnt not came from me, i just read it somewhere..
One thing for sure, using another app like that will somehow cause battery drain.. its a background process that keeps on running whenever your screen is on. Imagine how much juice is being lost watching a movie, games, etc. - Just a logic of mine btw.
Its just that, Sony somehow gave us a headache for that tint issues. Hopefully they will have a solution for that if could be done via software updates. Other than that, Goodluck to those who got an item with yellowish tint screens. White Balance ported app for Z1 hopefully will be done by @krabappel2548 or other great devs and it will be fine I guess because the source came from Sony itself, to be modified to run on different devices..
Thank you.

the screen adjuster i used b4 is a very very light apps, barely noticeable when it's running. of course, theoretically, any apps running is the background will consume additional battery. but in practical, the battery consumed by this apps, i personally have not felt any noticeable drain.
as mentioned, this screen adjuster is just a temporary workaround. a white balance port will always be better. a permanent fic from sony will be even better (hopefully)

[Q] Touchscreen issue?

Hello! Sorry if my English is not great, it's not my first language.
I have a Prestigio 3400 Duo and I have two issues with my touchscreen, the multitouch function in particular. My phone is freshly factory reset, done while trying to solve this problem, and
The first problem is pretty apparent, when I'm holding two fingers on the screen in a horizontal line it registers only one point at the center of the two I'm actually pressing (that's what a multitouch test app sees, at least). This happens exclusively in an horizontal line.
The second problem I have is when I'm holding two fingers on the screen and I let one go, the other one - the one that's still holding - is not getting registered for an instant before appearing again. So when, say, I'm playing a game on the phone and my character walks and I press a button at the same time, the character stops for a second. Really annoying stuff.
Is there any solution for either of these? I saw some fix for other phones but they're exclusively for those, not mine.

Well I don't know if it was something that I've done that caused this, I don't play many games so I've noticed it only recently. I can tell you that for a while the phone was rooted - now it isn't - but I've never installed CFWs or stuff like that.

Thank you, but there's no stock rom or a tutorial there, so...
I'm bumping the thread, hoping that someone that knows how to fix the problem can see this.
I'd like to at least solve the second problem, because the first one is barely noticeable to me. I basically can't play any game with the second issue because it's really annoying. I read that sometimes these kinds of problems are when you have an app that is used to block the touchscreen of the phone, but I've never used any of those so I don't know.

Faulty touch screen when typing fast

Whenever I type fast the screen registers touches that I don't do or small swipes. I originally thy thought it was my fault but now I'm noticing it more often.
Does anyone else have this issue? Maybe its a kernel issue or hardware? Using PA with Franco kernel
Sent from my One using XDA Premium 4 mobile app
Here you can see when I'm taping each side alternatively it registers another touch further in the middle, doesn't always happen but enough to be annoying.
OK its pretty hard to see, try yourself using screen touch test

I thought I was the only one with this issue. I was gonna reap my fingers off. Wow.
Anyways, I heard CM is issuing a fix coz it has to do with the kernel.
So let's hope there's a fix.
Sent from my One using Tapatalk
i've noticed this as well - can't wait for a fix i hate having to type slow -.-
omg this is one of the BIGGEST issues i'm having with the phone
when i type fast it sometimes registers a swipe left or down which will either delete the last word (Swiftkey) or make the keyboard disappear
its SOOO annoying...
i really hope this is a software issue that can be addressed
i'm coming from the Nexus 5 which was super solid and accurate for typing
i even tried disabling all screen gestures as per the other OPO threads but there isnt any difference
Same here, but for me some times the app i am typing on gets minimized. Does this happen to anyone else?

Personally I've never had that but I was only using cm11s for 1 day before I moved to Paranoid android. Maybe that's a ROM issue? I've heard of someone else having the same issue as you though
Sent from my One using XDA Premium 4 mobile app
I installed SwiftKey keyboard and see if it helped that issue. Sorry to inform, not by much if at all. Coming from a nexus 5 too and I thought I just wasn't adjusted to the screen size but it is happening regularly enough to make me suspicious.
this issue is becoming a showstopper for me
its like...70% accuracy or less
either it will have a phantom swipe to left or down for me, which will either delete the last word or make my keyboard disappear
i didnt have any of these issues with my N5. I have my N5 right beside me too and i type the exact same speed and its 100% accurate
something is totally off with the OPO touchscreen and i REALLY hope its a software related issue..

SwiftKey only helps the issue because it is better than Google keyboard at correcting errors when you type. The screen still had the same issue.
Surely hope this is a kernel driver issue that can be fixed. It has been noted by many people and apparently they are working on it or it has been at least acknowledged. I would be surprised if they we would let these phones go out faulty like this without knowing there was a resolution that could be reached....
Got my OPO in the mail on its way. Yet another thing to be concerned about.
Also currently running a nexus 5.

I thought it was my own personal error this whole time. Hope it can be fixed with a software update!
Guys, please help us all out and vote on this issue in JIRA to make it as visible as possible to the CM devs. Create a JIRA account, and then on the right, Vote for the issue and then watch it as well. Also, if you can, comment on it too.
https://jira.cyanogenmod.org/browse/BACON-55
There are a LOT of people complaining about this issue, and many of us are nervously waiting to find out if it's a hardware or software issue. I'm personally hoping it's a kernel fix that needs to be done on CM's side, or it's something that can be fixed with a firmware update from JDI.
BTW - for more visibility , I found this official JIRA ticket for the issue:
https://jira.cyanogenmod.org/browse/BACON-55
I hope it gets more exposure. I'm surprised more people haven't complained about this because it's awful.
It's really the only major issue for me though, everything about the phone has been pretty great
*EDIT
oh lol, looks like someone beat me to it haha
I am actually relieved to see other people experiencing this. I use Swiftkey almost exclusively, installed it first thing, and I thought they must have done something, because I have had to focus on slowing down how quickly I type. I am bummed to know it's my phone but relieved to know it's not just me.

No one said its a kernel issue on JIRA. I was the one who posted the issue first on XDA and someone replied to me and took the initiative to put it on JIRA. I've been following this from day 1, and the CM devs said they're looking into it. Never said if it will be fixed or not. We can only hope.
Also please notice the CM devs may have accidentally merged two issues into BACON-55. Please only talk on BACON-55 if your issue is related to fast typing and the multitouch issues.

app called 10292

Hi, I think I'm probably being thick (easily done) but could anyone tell me what the app called "10292" is and what it does?

If your phone is rooted perhaps you can use a 3rd party app to find out what this is

This has happened to me a lot. It usually happens when you remove an application which was on that list, the OS can't find it anymore so it shows the app ID or something like that.
