Weirdest Nexus 7 screen issue - Nexus 7 Q&A, Help & Troubleshooting

Ok i dont have much light bleed from the edges of the screen, i dont have (so far) screen separation, but on the other side, i have one weird issue with the screen, this issue just started about 4 days after purchase. Now I see some light (you read well) coming in the form of two little filaments, very short about a quarter of an inch, separated by black, now these light filaments are on the left side of the screen about in the middle, But they do not show where the screen is, they are on the black bezel, in vertical fashion, aligned to the screen about halfway from where the screen ends and the side begins, right smack in the middle of the black bezel, i believe that is the right word.
My question is obvious, what could this be??? ps. i know it is light coming from these cracks or whatever they are because when i turn up the brightness these spost appear brighter as well.
I am not sure i have explained the problem too well, taking pictures might not help....this is my issue, im asking you all for you help..
Thanks
Daniel

I've had the same issue. Strange light bleed from underneath the black bezel under the screen:

(This issue isn't visible in this photo. I marked where it is located).
Today i received my Nexus 7 from ASUS Repair Centre in Poland. They replaced the whole screen (LCD+Touch+Silver bezel) due to screen lifting. Now i don't have any lifting and this strange light bleed.

Did you resolve the light issue by sending the tablet to asus for the screen liftin problem? is it fixed now? could the light issue be a sign of a screen lifting problem in progress that is gonna manifest soon? i just dont know wether to think this is a big problem or a small one..

As I wrote earlier:
"Now i don't have any lifting and this strange light bleed." - after screen replacement.

No, I don't think so. That strange light bleeding was "out of the box". My screen started lifting after 1-2 weeks.

is this possible in WM phones, when you take the phone outa ur ear the screen lights comes on? just curious
I don't think there is a WM phone right now that has this ability, however most WM phone are set to turn off display automatically after few seconds when a call begins, and it turns on auto when you finish the call.
I just don't get the point of wasting the battery to power the IR sensor just to turn off the screen when its near your ear! when the OS can do that job in an easy way.
I'm not saying it's not cool thing to have , but it's not necessary.
cheers mate
Phones with light sensors can do this, such as the diamond.
Please ask your questions in the Q&A Section of the forums.
Touch HD/Blackstone has a proximity sensor, like the oh-so 'lovely' (ugh) iPhone.

yes there are wm phones with proximity and light sensors such as the the diamond/light, touch pro or fuze/light, touch HD/I think prox. the lg invite has a proximity sensor, I think the omnia has a prox too.
I think the light sensor is more versatile because u can have your phone adjusts it's backlight according to the amount of light around it.

Well, I wouldn't exactly say that. It has happened to me a couple of times that I accidentally ended a call with my cheek or by shifting the phone from one hand to the other and accidentally touching the screen. I have a Blue Angel, which is not exactly a small piece of equipment so changing hands during a long call is kind of a must (if you don't have a BT headset that is)...
Not a bad concept, however, duke911 has a good point. You can do this by software without having to have the IR, which is a pretty good drain in the battery, on all the time. Maybe a small script to change the lead time between the time the phone call starts and the time it takes for the screen to turn off. I don't know jack about programming but it doesn't seem like a difficult task...
Please move this discussion to the Q&A section

A surprising fix for Proximity sensor problems

Hi there,
Quickly after installing a new screen protector sheet on my Motorola Defy, I discovered that it is causing my proximity sensor to be next to useless.
By peeling off the screen protector off the proximity sensor I verified the source of the problem. (The sensor worked properly without the protector sheet on it.)
I used a black permanent marker to mark out the proximity sensor area, to cut out a little window through the protector sheet with a knife.
Drum roll please, we arrive to the part where Newton got an apple to his head and Archimedes ran naked out of his house yelling "Eureka!",
The black permanent marker fixed the problem. once I painted over the proximity sensor (On the screen protector sheet of course!!), It started working fine again. Yeah. Weird.
Yes, Yes, I know, this is life changing information for many of us who just couldn't hang up after dialing the wrong phone number because of sensor problems...

wow.. epic fail on the part of the screen protector maker. did you bring this to their attention? good thing it has an easy, albeit, chinsy fix!
Long ago, I discovered something similar on the myTouch 3G Slide. That phone has a small rubber box cover over the proximity sensor, with a small hole for the sensor to peek through. When I changed the flex ribbon cable, the sensor wasn't working anymore. I eventually realized that on the old cable, there was that small rubber box over the sensor, & the new cable didn't have that. I put the rubber box over the sensor, & now it worked again. It seems that if the sensor is left wide open, it won't work right. I notice that on newer phones, the sensor is usually encased in its own little box in the housing. I guess they need most light around it blocked off in order to work right.

-nah, just a cheapie on ebay
This is a well known fix for the proximity sensor issues with aftermarket replacement iPhone glass that doesn't have dark enough tint over the sensor.. (cheap import products not oem) good to know it works in this case too.

New display shows vertical line

Hello! I had 1st gen nexus 7 laying around with smashed lcd. I ordered new one from china and changed it, but my new display looks faulty. I wanted to ask if someone had similar experience.
New display is split on vertical axis. and left side looks a bit darker. most visible is on white background

sometimes there is a thin line seperating both parts.
line disapears if i switch windows or re- wakeup the device.
there is also a flicker on the left side when i wake up the device.

the dark and bright sides do not change when I turn the tablet around. display orientation changes but vertical split stays in the same place.
when I first changed the display and turned on the tablet it started to flicker like crazy and un-readable after few seconds of loading screen (google logo was fine and few seconds of spinning colored bubbles too)
I got it working only after full wipe/factory reset.
any chance the vertical split could be software issue? or should I return it?
Thanks!

Or you broke something when changing the display or the display is garbage
Typically this is from dirty, damaged or not fully seated connectors in my experience.

+1 Exactly what I was going to say. If it were a faulty display, most likely the issue would be constant and on all views.

Proximity sensor...

Hello.
I would like to ask about the operation of the proximity sensor in S20 (Exynos).
It sometimes happens to me during a call that the display does not go out when I hold it to my ear.
It's really few times, but it will happen.
Does the proximity sensor work at 100% or is it a defect?

When you are at a call, you'll see the top part of the screen flickering next to the front camera.
Thats the proximity sensor. Put a finger there to see if the screen goes dark.
If it does its working fine.
If it doesn't it's defective.

When I move the phone, the sensor flashes, when I don't move the phone, it does not flash, but the display goes out, but sometimes it happens that it doesn't go out until the next movement.
When I select the code *#77692#, the sensor still flashes and works at 100%.
When making a phone call, the sensor flashes only in motion, the pixel does not flash at rest, a lot of people have written to me that they have it the same.

Try going to settings- advanced features- motions and features. Then disable the lift to wake phone. That might be causing the problem.

Heat damaged display (Samsung S8)

I‘ll really appreciate if anyone can explain or possibly fix the damage of the AMOLED display/screen on my Samsung Galaxy S8. The screen has a few odd characteristics after it was accidentally damaged by heat. (Because I put hot takeway food into my bag that has my phone in it.) The screen started showing the following problems after the accident.)
1) the screen has a permanent yellowish/greenish tint
This tint is visible even in the boot up device name & Samsung logo screen, so I don’t think it’s caused by software. This makes the colours on the screenlook less vibrant and less saturated.

}
2) the screen cannot display pure black.
In the black background of pictures in gallery and especially while charging when powered off, it is easy to see that what’s black is now gray. (Refer to photos below) When the phone is off, the bezel and the display is the same black color. When the display is on, the grey color makes the top and bottom bezel of the phone visible. On all Samsung AMOLED display, the black part is not supposed to light up because it’s an OLED display, but now it appears like an LCD with backlight bleed.
3) always on display doesn’t work anymore and show something like a static screen during always on display.
(refer to the video:
)
The clock and home button doesn’t show and the screen will show that weird static effect slowly. (takes around 30 seconds)
4) the screen is unusable at 20 to 80% brightness
(refer to the video:
)
At 20-80% brightness, everything on the screen become blurry and any animation causes ghosting of the image. On a non white image, the display will form horizontal white lines across the screen, obscuring the content on the screen. Strangely, none of the problems occur when the screen is at 0-20% and 80-100% brightness, the display appears normal and perfectly usable.
(This is the dealbreaker that forced me get a new phone to replace this S8)
Looks like a blown driver(s).
Try clearing the system cache and a hard reboot but I doubt this will help.
A hard reset will do nothing.
I had sunlight + charging blow out the drivers on my S4+
$hit happens...

I was hoping that the display could be recalibrated for the brightness and color issues, but I don't know if the display itself or the driver embedded in the motherboard is physically damaged. Replacing either component is close to the resell value of a good condition S8, so I don't plan on doing that.

I assume the damaged drivers are on the display assemby* but not sure if they're drivers present there.
It seems the logical place to put them though.
White papers for these devices seem nonexistent. There should be service manuals but I've never seen one.
Blowing out a display sucks...
* most likely fully integrated into the display itself.
