On occasion when I'm viewing stuff on the n7, I'll get a vertical line of what I can only describe as feedback or something about 1.5-2" from the top of the screen (portrait mode). It looks like its just one pixel strip. It's very fast then gone. Anyone have a sort of issue like this?

Does anyone know of any way to get better digitizer accuracy on this tablet? If I draw diagonal lines with any kind of stylus, the lines are always wavy and it's extremely frustrating to attempt to draw anything. I rooted my tablet in order to use the screen calibration tool in the market only to discover that it doesn't work on the tab 2... I guess I'll have to stick with drawing on my much smaller galaxy nexus for now.

The screen is accurate enough. There's no need to calibrate your digitizer, because the problem is - STYLUS.
Try to draw something with just a tip of your finger, it would be more accurate than a draw with a cheap stylus.

I have to disagree here. I've tried both dagi and cheap stylii, both have the issue on this tablet. If I go to my galaxy nexus with the same stylii, guess what? They draw straight lines.

The original galaxy tab 7" had the same issues, and the screen calibration app in the market allows adjustments to it to make it better. I have done a lot of reading on this and the difference these adjustments make is drastic. I wanted to see if anyone knew of anything similar for the tab 2, but instead I am met with people who are eager to reply without even doing the minimal amount of research or even have any clue what they are talking about.

It looks like the tab 10.1" also has this problem:

The touchscreen calibration information seems to be stored in melfas.bin firmware file since the tab 2 uses the melfas touchscreen driver. There's nothing to be found in the driver source or in sysfs. I've looked.
But you're right, I probably don't know what I'm talking about.

Was referring to the guy who told me I was using a cheap stylus when I never stated what I was using, and used both cheap and high quality stylii. It's frustrating to look for answers first, then ask questions, then have someone answer with false assumptions.

Dralanmage, did you ever find a solution to the screen calibration issue?
I notice that the majority of the screen is accurate. However, the edges are out by almost 0.5 cm. I verified this by tapping settings, developer options, show touches. I'm using the Samsung Galaxy Tab 2 7".

Nope. The screen is fairly accurate with a finger, but always draws wavy lines with any kind of stylus. Even with a finger, the lines are wavy. However, the amplitude of the waves is much lower so it's not as noticeable.

Same with the vzw tab. Scrolling in landscape is annoying as hell unless you add more finger surface area..

I got my Nexus 4 yesterday, and just today I've noticed that when in dark screen (locked, or simply the settings page) and outside of the house I see kind of weird black lines on the whole display screen, going form top to bottom making some 3 small square shapes after the others all over the display, can be obviously seen when display facing bright sky outside in almost any angel, but in room light barely can see them with certain angels.
will make a photo of it asap.
p.s. I've never seen a notification light yet on the middle bottom of my device.
Anyone same "problem" with display?
Its the digitizer.

Could you link an example image from goolge or something to make sure it is what I mean? can't seem to find something alike..is this normal?
I can confirm that its the digitizer I too have found that with this phone it is very easy to see even with weak light I see it when I get the right angle. It looks like you described but the vertical lines look more like dots arranged neatly than lines on mine.

Just noticed the same thing on my device. Thought I was tripping out maaaaaaan

Its the digitizer, its normal. I think its because of the "zero gap" technology thing ; the display and the digitizer are right below the glass.
As for the notification light, download Lightflow from the Play Store. Works great.
Sent from my Nexus 4 using xda app-developers app
For the notification LED, make sure you enable the " Pulse notification light" option in Settings->Display. Using Lightflow on top will give you lots of customisation options though.

I am now noticing the same issue in my nexus 4. If it is because of zero gap technology then why it is not there in iPhone 5 and other phones which use this technology?
I also notice that my brother who got the phone some time in November 2012 is not having this issue. I got the phone in Jan 2013...is it issue with only the new lots?
What google and LG are doing to address this issue?

Its the digitizer. I mean seriously why are y'all complaining about that, its normal.

I have 2 Nexus 4 (one for sister and one for girlfriend), which were both purchased last week and arrived this week. Both their serial number starts with 301K.
Here is the weird part: for one of the phone, it is very easy to see under the glass. When there is adequate lighting and the display is off, it is very easy to the see the circuit-like component just under the glass. This is not true for the other phone. The display also has a more of a yellow tint than the normal one. Otherwise, the display looks and works fine.
Anyone else also experiencing this, or know what's the cause of this issue?
Thanks!
This is how the pattern looks like under the screen:

It's because the touch screen sensor (I don't know the correct term) is closer. Basically it isn't an issue, it's a design. Nothing to worry about.

Alright, noticed that a few days ago - bottom part of screen, a navigation bar, is burned out, and that's kinda sucks!!! I can clearly see it in full screen mode (YouTube, games etc). Looks like a burned out old ass crt monitor lol.
So, if anyone having the same problem? Is this a reason to RMA? (Bought my phone through Google, December 2015)
Upd: top of the screen is the same, just not that noticeable than bottom(...

It can also be just an after image, not sure how its called exactly, but long story short if you leave screen on with white red green etc colors on for some hours it will go away. There are apps designed to do that
This has happened to some extent on all my amoled phones. It's the compromise you make for such amazing blacks.

Just wondering if anyone else notices screen flicker at low brightness on the Oneplus 5. I noticed it immediately as I was setting up my phone, and while I haven't used an AMOLED-equipped phone since the note 7 briefly last year, I don't remember seeing it on that phone.

It is because of AMOLED.
Is it all the time or only when there is animation?
All the time. I've actually gotten used to it pretty quickly though.

AMOLED has that problem. Not an issue for me, but try this to see the effect.
yes
yeah, i start seeing this for 3 days specially when i put reading mode, until today, it changes to black color and the screen stop working
I've completely gotten used to it now - don't notice it at all
