[Q] Phantom screen "taps" error

I have a very constant "phantom tap" on my Note. It is always in the same place on the screen - the very center, bottom area (I get to see a lot of S Memo). It was not a problem until today and does not happen very often when charging.
It makes the Note almost unusable and I bought mine off of eBay so don't think I have a lot of choices for returning.
I have seen reports of these phantom attacks on other devices but not on the Note. Don't know if it's hardware or software related.
Any thoughts?

Could it be a batteey issue as it works better when being c harged?

I have similar problem, I can not use the Swype because it is happening all the time as if lifting a finger or tapping en Another place and the words are wrong

This is an example of what happens. If you look at the pic you will see a group of dots in the upper right corner. I had the phone in landscape and the dots appear at the very bottom edge consistantly as if I was tapping the screen. This is a real annoying problem. Makes the n7000 almost useless.

Before I throw the towel in on this phone I am going to try a new battery on the hope (small) that this behavior has something to do with power delivery from the stock battery.

Does this graph look reasonable? It seems to me that the battery temp gets hot quickly and there seem to be a correlation between high temps and phantom screen inputs.
Thoughts?

Same issue for me on the standard (now old) XXKKA rom. Just at the bottom, left of centre - plays havoc with my wordfeud!
It was only occurring at night when I used my phone more which made me also think it might be temperature related, but now happening more frequently during the day.
Loathe to have to take it back for repair, warranty covered or not, so if anybody has any ideas about whether it might be software related I'd be grateful to hear them..
Thanks

Hey Phil
Yep, sounds like the same symptoms that I had. I thought temp was the issue for a while and then maybe battery because it did not happen when the phone was charging. Even after buying a new battery the problem continued however and ultimately the Note became unusable.
I was lucky and had a good seller via eBay who helped me return the Note to NewEgg as it was within 30 days of purchase. The bad news initially was that NewEgg was sold out and so I could not get a replacement unit. The good news is that going with the AT&T branded Note will be a better option for me at the end of the day so I am looking forward to getting that.
Good luck with the issue but I could never get any worthwhile information on the issue.

Anyone else having a line down the screen?

I have had the N7 for 5 days and after an hour of gaming (on the 23rd) I found the battery got very hot and that a line appeared down the screen. At first I turned it off thinking it could be solved, but that did not work. The line is a red line that goes down the screen form the camera down and is perfectly straight. The other thing is that it is above the battery where the device got hottest.
I am returning the N7 and getting a replacement.
Anyone else having this problem.?

Not mine, but someone else reported a red line on their screen out of the box.

Ok, I am replacing it but have not yet received the shipment sheet via email to stick on the box. Overall the service they have is quite good but i am a little concerned that they are having a lot of people returning.

I have an black horizontal line in the bottom section. Just sent an email to Google asking what to do.

I got a red and blue line going down my cell phone screen. The replacement screen should be coming today. If my N7 has something wrong with it after I have waited this long for it I'll be real bummed.

I have the same problem. What do you mean 'replacement screen', google just send you a new screen without returning your pad?
I prefer they sending me a new screen and I fix it by myself too.

I thought people did lines down mirrors? Nexus 7 could work..

I had a rainbow colored line down my screen new out of box, Google sent a new unit the return process is painless.

Odd lock screen issue/glitch (white line across screen)

Just noticed an odd glitch on my Nexus7. When I press the lock screen button I notice a 1px heigh white line that varies in length, but normally about half the width of the screen and can be seen about half and inch up from the very button of the screen.. The line is visible approx 9 time out of 10 when locking the screen.
Has anybody else noticed this? I'm currently undecided if I should return due to a slight screen flicker in gmaps but if this is a real fault I guess this will help me make my mind up.

Does it show then go away with in a few of milliseconds? Mine does that very rarely
Sent from my Nexus 7 using xda premium

Yes that's it... To be honest I wouldn't normally see it as I rarely lock the screen manually, but I did this morning and noticed it. Think I may just leave it then.

I think I have a different issue from you guys and was wondering if you ever experienced this. Occasionally I get a vertical white line across the screen for a couple millisecond after I wake the device from sleep into the lockscreen.

I get the exact same thing on mine. I thought I was imagining it at first as it happens so fast. I would be interested to find out what it is.

Do you get a vertical white line or horizontal?

I'm glad I'm not the only one.. Mine is only horizontal and stays the exact distance up from the bottom of the screen each time. I'm guessing its not a major problem and I'm quite happy to live with it. Just hope I haven't stumbled upon another Nexus7 issue.

LG Service Center complaints

I bought my N4 on 22-3-13.
it is a great device and i tried calibrating the screen before sending it in.
i had a REV11 unit.
anyway my problem was that i was having really yellowish tint on all screen but specially from left lower corner.
but the most annoying were the huge black spots especially on the upper side-center of the screen.
ok i did not worry cause some told me that that was just glue waiting to dry (well that is just BS).
the spots became larger and easier to spot when phone was getting hot( normal hot) and my eys were getting tired by that ( i guess because knowing where it is was making me concentate on that).
so i sent it to LG service here in Greece-Athens explaining the problem and along with the phone i sent a comparison pictire with another N4 of a friend.
their response toward me was " We see nothing. it is perfect. we are sending it back to you"!
lol. i asked them to keep it and contacted the customer protection agency.
2 days later LG calls me and says they are exchanging my motherboard. i asked them why, 2 days earlier you found nothing?
the responded it was the fault for the bad screen.
so they sent it back and guess what, the problem is still there and they sent a REV10 which i δon't minδ that but the previous board was flawless.
so now i am very pissed and will send it back on monday but to conclude, how dumb do you have to be not to exchange the screen and instead chang the MB when it is clearly the fault of that?
P.S: which one you think looks better?

The left one for sure is better

that is my point. they said it is the same. everyone i have asked say the same.
also a third one looks just like the left one. great

Personally, I don't see a problem with either. There will always be minor variations with screens.
If you want to be really picky about things, the left one that's "better" has a blueish hue on the top 1/3rd of the screen. I'd rather take the right one, but that's the point it's all subjective.

It looks like gamma variation. IMO the right one looks better. It looks like it has deeper blacks.

Are the brightness levels the same on both of the phones in that picture?
I know there are screen variances with this phone, though many don't believe. My coworkers Nexus 4 scree has washed out colors, whites aren't white, and just plain doesn't look as good as all of the others I've seen.
Some reviews you see on the web talk about the screen of the N4 seeming washed out. My phone isn't washed out in the slightest bit.

it's not even close.. the one on the left looks great, the one on the right looks like sh*t
You'd have to be blind not to admit that.

I just replicated the exact same thing with my friend's N4.
1) Gamma/Saturation can make it look exactly how yours do.
2) Brightness, I've got one set low and one set high and they do the same as what yours do...

I like the one on the right

Personally seeing issues like this makes me understand why companies lock bootloaders, and try to chase away modders like most on XDA. We are the most pickiest of all cell phone uses. We create problems that don't really exist and brick more phones than anybody else.
Having two phones with two different color tint is perfectly normal it happens all the time with big screen TVs. A manufactured doesn't always use the same supplier to supply a LCD screen Hance the different color tint.
Just get on with your life enjoy the phone and stop looking at a white screen

I was in the cell phone industry for over 10 years and this is a normal variation. Literally it happens all the time you probably might not have noticed if you had not had two phones next to each other. If you had brought that back to my store we would have told you it was normal. If phone manufacturers replaced phones for minor variations they would not be. If you don't like it sell it.

Yellow tint goes away after one week of using the device. Or root it and put your own screen values.

If they did that successfully, your phone would suck bro. The "modders"as you so elegantly put it are the reason things improve. Don't believe me? Look at how many 3rd apps turned into features that Android uses now as part of their OS. Linux is beautiful because of open source and sharing ideas. Go buy an iPhone and "get on with your life". It's consumers like you that allow mfgs to cram crap down your throat

Nothing against "modders" as I'm one myself. And I do appreciate the work that some have done on certain devices. But I mostly talking about the nitpicking, OCD'ing flashaholic that return devices after devices for minor imperfections like a squeaking volume rocker or yellowish tint, I can name a million more things but lets leave it at that.

yes they are absolutely stock. brightness 100% manual mode

it is not only the colors, it is the black spots too if you read my OP. they make my eyws suffer just by knowing they are there.
it is not a taboo to ask what you payed for, which is an perfect working gadget. and i payed almost 500 euro for that.

just so you know i am in the mobile phone industry.
i have a service center for mobile phones. i do not want to mention which one i represent.
i am not talking about color variations or lcd suppliers, i tried to calibrate it, but nevermind that, as i keep on saying the spots make the difference.
and i never asked the service to change the MB. i was very specific describing the problem.

you can just peel the mylar of the on/off button and scratch it or clean it with glass fiber.
remont the mylar, remont the switch, assembly the phone.

with that line down the middle it seems like it's a permutation of the screen tearing effect.

Known issue on the Nexus 6. Some devices the screen will "split" or tear down the middle and be unresponsive. I've had it happen. Your picture shows a definite line down the middle of your screen and I wonder if it is just another version of that issue.

line through screen
Hi guys
I too have the same issues with the Nexus 6. I notice it every time I watch netflix. Watching it horizontally, I will hat a horizantal line in middle and then sometimes even a vertical line. SO it looks like 4 window panes. I have to shut off phone to correct issue. Please let me know if you come up with a fix.
Thanks

Does the screen go black, or does it freeze. If it is the latter, most people say an RMA will resolve it.

It continues playing the movie with the black line. I have read this happens often w Netflix our this phone.

Happened to me too. I've read that for some people locking and then unlocking the screen solves it but I had to restart it to bring it back to normal. The screen stayed responsive though.

I can only assume that no fix for this has been found. I also have the issue, though turning off the screen and turning it back on fixes it until the next time it messes up.

My nexus 6 started having this problem from a few weeks ago. I think I saw the black-line-in-the-middle issue initially as well, but the prevalent issue for me right now is shifted or wrapped-around screen (need to figure out how to post a picture - this is my first post). The amount of shift sometimes varies (as much as half of the screen), and the video playback is not affected (phone works fine other than the screen shift), and screen is not frozen. I have had the phone for about 6 months (T-mobile) and it's not rooted and it has the latest android version (5.1.1 I think). Initially it showed up when playing netflix for a while (like 10 minutes), then it happened in youtube as well. It only happens when the screen is in landscape mode, and it does not happen every time. Turning off the screen then turning it back on does not make the problem go away. Only reboot can fix the issue, but the problem will come back after some play time.
I haven't seen any post talking about the same problem, let alone people talking about this kind of problem 6 months after using their phones (most screen problems reported are within a few days after the phone was received). Anyone has similar experience? I haven't talked to t-mobile yet but I will. The last android update on my phone was from a while ago so it shouldn't be related to that, but it could be related to netflix/youtube app updates but I don't remember when I updated last time. I am also using a phone cover with a lid which I expect would make heat dissipation situation worse but I started using that cover many months ago so I don't think it should be related either.

Not same issue I'm quite sure but I had a small think black like going across my screen, just appeared one day... This line didn't quite touch the edges of the screen but had an even gap on each side where it ended. I did a factory reset and no dice so I ended up taking it back to Sprint and after attempting to tighten a ribbon and they could not fix it they ordered me a new one and I see now that my og N6 was indeed defective as the speakers sounded completely different and on this new one speakers don't sound like crap.. Tk God for insurance. :thumbup:
