Nexus 7 touchscreen dead spots

So i've noticed a very strange issue with my Nexus 7. If I wake the tablet up while touching the screen I get some very strange touchscreen behavior. It's almost as if there are dead areas on the touchscreen that don't respond to touch. If I put it back to sleep and wake it up without touching the screen the issue is gone. I've made a youtube video demonstrating the issue but I can't post the link yet since I haven't had 10 posts yet. If someone PMs me I will message them the link so that they can post it to this thread.
Has anybody else experienced this issue?

I'm having the same issue. I noticed it while typing.

Any specific areas that are less responsive? I wonder if there's a touchscreen calibration app for the Nexus. I know there are for other devices.

+1 Definitely noticing this. It appears to occur randomly and inconsistently in different regions. The same region will not go dead again, necessarily. It seems as though the screen simply does not register those touches.

It seems to be towards the center most of the time and the dead zone appears to vary in size. It's possible the dead spot may center around whatever part of the screen was touched when waking the device. I'll have to do some more testing to see if that is the case.

Just got mine and it was sitting outside in the heat and the touchscreen was not responding well when I first turned it. After it cooled off and installed the update every thing is working fine.

Here is a video from the OP. He asked me to post it for him.

Is it possible that the capacitance of the screen is calibrated upon wake or something? Not even sure if possible, but it's a thought.
Edit: a drawing app may allow you to demonstrate a little easier.

I don't know if my issue is related but scrolling is totally inconsistent on my n7. Usually when I swipe it'll work correctly but one out of five times a swipe will be registered as a tap. This gets really annoying when you're trying to scroll but end up clicking something instead. Wonder if my n7 is defective.

I don't have my N7 yet so I can't test it out for you but that's definitely weird. Can someone with an N7 try to duplicate the issue?

I've also seen this happen on occasion when I trigger the issue. Swipes will sometimes register as clicks...

A good way to confirm the dead spot is to download a drawing program and see if there are breaks when you try to draw a straight line. Even though I can replicate the dead spot when scrolling, everything seems fine in the drawing program.

This is an Android problem as far as I am concerned. All of my android devices have typed funky while charging.

I tried this out in two drawing apps and got different results. In "Draw Free" when drawing vertical lines my line would stop at the beginning of the "dead" spot and pick up again on the other side of the "dead" spot. I could not replicate the issue when drawing vertical lines in the "Picasso" drawing app.

Not seeing this issue on my Nexus 7. Not very helpful in tracking the problem, but I figured it was worth mentioning that this doesn't seem to be global. I'll post again if I manage to replicate the issue.

I enabled show touches in developer options when it started happening, and I saw ghost touches nearing the middle left side of the screen when nearing areas with dead spots.
Seems like a grounding issue internally causing the touch driver to short in some places.

If it is due to a internal grounding issue I don't think it will be as simple as a software fix
I am on the fence on whether I should try and get mine swapped out with a new one at GameStop...At a minimum I am going to try and call google support at some point today and get their take on the situation.

I would definitely swap it out.

Hello to all. I don't have an Nexus 7 but i do have Nexus S and i noticed from some time when i take out the phone from my pocket if i touch the screen and then turn it on the display was not responsive on touch but did not make some tests to see if the touch before turning on the screen was the exact problem. Now i saw this thread and tried the "pointer location" in Developer options and got this:
Turning off the screen.
Put my finger on a chosen spot.
Turn on the screen.
Unlock.
Try to draw a line passing through the exact same place where my finger was when i turned on the screen.
The line get to the point and then make a half circle around the spot or it break the line and then continue after the point where my finger was.
After turning off and on the display again the non responding spot disapear.
Sorry for my bad english

I too am having this problem.
I bought one at Sam's because i was sick of waiting on the play store....now I'm trying to decide if i should take delivery in the hopes that the touchscreen bug is only on some...

Screen Brightness issue

My phone keeps turning brightness way down by itself with this message. All temperature readings are fine. Any ideas?

I too am having the same issue, however i believe that my issues is slightly different from yours. I noticed maybe about 2 days after i purchased the phone that mostly anytime I am using the browser, whether it be Chrome or the stock browser my screen automatically adjusts itself. I went into settings and made sure that the brightness was not set at "Auto" and turned all the way up. I also made sure that reading mode, auto adjust screen tone, and color adjustment were all turned off. I also changed the screen mode to dynamic and I seem to still have this same issue. I read on another forum for T-Mobile users that there are a lot of consumers experiencing this same issue, not sure if carriers are doing swap outs for the phones as this may not be related to a HW issue but rather a SW issue.

That sounds exactly like what I'm experiencing. Except I work outside, so when it does this it's impossible to see my phone. If you get a chance the next time this happens can you go into settings and open the brightness slider to see if you also can get this error message to appear? That seems to be the only place I find the message, it doesn't just pop up or anything. I too have checked like 10 times to make sure all the other display settings are correct, like automatically adjust tone and such. It sucks that auto brightness cannot be fine tune with the slider like it could on the note 2. I'm finding it very strange that instead of adding to features of the Note 2 to make this phone better in every area they chose to remove some great features leaving me wishing I did not upgrade.

It sounds like thermal throttling. LG phones have this, in particular the Optimus G and G Pro. I haven't had the problem on my G2 yet. It's designed to lower the brightness and lower the cpu speed in order to keep the phone from overheating.

True my LG Optimus G pro does this but there is a way to turn it off in the system menu accessible from the dialer. I have turned mine off and the phone no longer does this and has not gotten hot or anything. Wish there was a way to do this on the samsung as my S4 exhibits this same behavior.

I'm thinking about getting a Note 3 today so I'm hoping can be shut off too. I shut it off on my G Pro and the G2 doesn't do it, which I'm very thankful for since I work outside as well.

Since we're on this subject, how often does it happen on the Samsungs? I would figure less often due to amoled not being as bright as LCD.

You may be better served to leave the auto brightness checked when your working outside. When on auto, it gets much brighter when needed than with the brightness slider cranked all the way up.

Note 3 automatic brightness settings problems
I have a Samsung Note 3 phone bought in Germany. I have the some strange problems with brightness settings too. Typically from time to time the phone screen just get too dark. Particular in economic mode the phone can get from time to time very dark and even setting auto brightness to +5 does not help.
I was using before both Iphone 5 and the first Samsung Note and some other phones and automatic brightness control was always working fine. In my new Note 3 the brightness is jumping sometimes suddenly.
JVogle: You can adjust the automatic brightness by pulling slider up or down. It can by set from -5 to +5. But in my case this thing do not help so much. Particularly this is a bigger problem again in economic mode.
This is rather a software issue, because when I switch to manual brightness it stays constant all the time.
Anybody knows how to cure it?

This is so annoying. Gotta wonder if it's a bug in one of Samsungs ****ty features causing it to happen so much. Even without brightness all the way up it happens

You have a different phone than me apparently. Also a different issue, as I'm referring ONLY to manual screen brightness setting. I would expect fluctuations with auto brightness. I've never had a device fluctuate when manually set to a desired % though. I also can't believe they removed the ability to adjust slider with auto brightness. Sadly the only thing better about this phone than my Note2 is the specs. The software and user experience has been sub Note2 for me in every aspect. I will most likely be switching back to the Note2.

brightness issue
I have tmobile and I've had my phone for about a month and now I notice when it's in standby and I hit the power button to wake the phone the screen is really dim for about 10 seconds or so and then it brightens up. My brightness is on max and the auto brightness is disab

[Q] Note 3, Google Maps, & Arrow Pointer

All
I've been having a really annoying issue with my Note 3 and Google Maps: the dot-arrow that shows my position is pointing in the wrong direction. Yes it does track me per the gps location but the issue is that as I am driving instead of the screen moving from up to down, usually along the length-wise direction, it moves at an angle or across. The only option I have is to hit the location button so that I can always have the top be North. That's not as good as having the heading pointing to the location of travel. Now, I calibrated and recalibrated the compass with GPS Status App (turns around the axes and figure eights) which seems to have worked for some, I have restarted numerous times even after turning on/off location-based services. I have cleared the cache and the google maps data. I have reinstalled it. I have even checked the compass versus real settings - seems to be pointing in the right direction. I still have the same issue. This is very frustrating and disorienting when driving. Looks like a crab moving angled to sideways across the screen.
I am on the latest Stock KitKat 4.4.2 version and Maps 7.7.0.
So, does everyone have this issue? Does anyone think is is a unique configuration issue? Is this a google maps issue? Any thoughts on how to fix?
PS...other Map Apps seem work fine (but like to use Google Maps due to the excellent traffic option)

If other apps seem fine, it might be Google maps. I don't have that issue, but I use Google maps version 6.14 (the old style with location arrow). The note 3 is notorious for all of its gps issues, but if you have good signal and it doesn't cut out then all I can think of is that GMaps is the culprit.
Sent from my SAMSUNG-SM-N900A using Tapatalk

I noticed this issue too! I believe it has to do with being inside a vehicle. The metal may be interfering with the gps signal. If I sit in my car and hold my phone so it points north, the arrow points south. If I open the door and step out (while still pointing north) the arrow magically flips! I can fix it by doing figure 8's in the car, but what a pain!!

Well, I do agree it is a google maps issue. I wonder if I can install older version to check. It only recently happened to me. I do not think it is an in-car issue because I never had the issue before when I was navigating in the car. Will come back if I can side load an older version of gmaps.
By the way, this issue is all over the internet but none of the foxes suggested seem to work for me.

No luck in getting it fixed. Did back down to earlier version of 7 but still had the same issue. Driving me nuts.

navfree... can preload maps but just uses google search for most things. some things arent great but its getting better. ive had the same issue with google maps. its been super sporadic. not a deal breaker...

So excited when I started reading this thread, figured someone would have a solution...lol Had this problem ever since my GSII Skyrocket, the gps works great but the direction is always off in my car... Can't understand what the problem is. Done the calibration to no effect... Hopefully someone who knows how to fix will pop in and steer us in the right direction...lol

I'm also waiting for a fix for this..
Ever since 7.0 "update" its been like this. I tried everything but no luck.
I'm using Exynos Note 3.
I was using an HTC EVO 3D when I recieved thr 7.0 update. Before it was fine but after the update even my HTC started doing the arrow pointer bug, and its still happening on my Note 3 even after the yesterdays maps 8.0 update. So I'm thinking this is all Google's fault but nobody is admitting anything.

Hit *#0*# , then select sensor, little black compus will have red line in middle on bottom left of screen. Shake phone vigorously, line will turn green..... This will fix that issue;however, if you reboot phone, you will have to do this again.
Hope this helps someone.

Any solution that needs to be applied again after a reboot is not a solution at all (nothing against you, just frustrated at no solution).
I have the same issue as the OP, and GPS status app fixed it, but I lose the fix after a reboot. This is unacceptable and I don't think it's just a few of us experiencing this issue.
Could more people post and say whether they have this issue and if not, how they fixed it?

Sick of samsung's bad displays

So my display after being replaced 2 times in 6 months started flickering. My phone is very hard to be turned on because of the green flickering.
I just want to upgrade to a S6,S7 Edge or non edge. i just want to know if they have the save problem with displays ? I want to have a phone at least 2 years, can you recommand me a phone like that ?
I was just considering switching to a iPhone even though i prefer android on phones ... o how are S6,S7s displays ? Samsung still have the same problems?

Samsung improved a lot on screen quality in S6 and after, so you should be okay

Wow that's amazing. Been using samsung s5 exynos version for the last 1yr. Never had that kind of problem till date. And it have the same display as snapdragon version. And on comparison I found that this is by far the best display out there when compared to other brands.
Maybe perhaps you might be having a faulty unit from the begining.

I have the same problem here with the display and it's not a software problem (same by original os 6 and same by cyanogenmod 14).
After the temperatures are under 10 C. i can't open my s5 with home button i must do it over the power button.

Using S5 for more than 28 months still I have not faced any issue. I just had to buy new charger apart from that not a single problem and yes I mess up with my phone so much but I still working and no display failure yet. And also I have dropped it many times, it still refuses to die.
You are just having a defective model or some internals of the phone are messed up. Because Samsh*t produces one of the best displays..

Its not a good sign. Try disabling your light sensor. Even then if you experience such a problem than it means that your flex cable that attaches the screen with the motherboard needs to be changed.

Hi,
Yes and expect the same problems with the following generations. It's an amoled screen thing. The green colour happen when there's a colour displayed on the screen for a very long time (for example, I have a green on my screen of the size of my keyboard).
I think a solution to this problem is to set the display to turn off after 30s (it saves battery too) and maybe, if you're using a custom keyboard, change the colour from time to time. Use the brightness of the screen to a lowest which would still be comfortable to you (and auto unticked).
This last tip alone is enough to prevent greening. My flickering happened after an incredible fall (it had a tempered glass so the screen was safe). The flickering showed green what it had in memory.
Samsung has a 2-year guarantee for its products so you shouldn't worry for that period of time. Problem not solved, replacement.
Best of luck

The funny thing is i already did "by mistake" all the tips you said and still have this. Never dropped the phone though. This problems seems very big though, i expected a burn in to be the biggest problem, but to have flickering at a level that i cant turn on the phone. I wanted recently to switch to a Nexus 6p, but knowing that it uses Amoled too, its a bad ideea. So the only "solution" is to switch to IPS screens? (btw i want a phone that holds on for at least 3 years)

In my research thus far, the AMOLED screen technology is to blame. When the display circuits get old or damaged, they don't sustain current at low power settings. In LED screens, a back light controls brightness, but AMOLED screens send current to each pixel for brightness control. If the circuit is damaged, or any corrosion has built up inside, this could attenuate the current below the point required to sustain light flow. I see this problem with some LED and CFL lights on motion sensor switches. Just enough current goes through the motion sensor to keep it's circuits active, and that current causes a flicker in the light.
With the screen though, since the problem is only resolved when you increase the brightness just a bit above minimum, it seems anything that lowers the display power (auto brightness for example) will cause it to flicker if this setting gets too low. I also noticed that before the screen locks on timer, it dims to low power for a few seconds and flickers as a result. There are apps that attempt to resolve this by putting a translucent black screen over your desktop and apps. This keeps the power up on the pixels but adds a black overlay, kind of like a screen filter. You can adjust the darkness if you need it to save your eyes when reading in the dark but it doesn't help save power any. They also require a rooted device, which could void warranties. The reason for this I believe is because apps are supposed to operate in a way they don't intrude on each other, and a filter that lays over your screen does in fact alter the output of your display rendering. With the added security concerns of these apps possibly collecting screen shots and sending them to another site, I would avoid this. Best to use a physical screen overlay you can put on or remove as needed as long as it doesn't interfere with your touch screen options.
Ultimately, these devices were meant for replacement every 2 to 3 years so if you're like me and you like to make your investment last, best thing to do is apply any work around you can come up with. A repair shop may be able to wipe the circuit boards down with a solution that clears away corrosion, but it won't repair any weakened pixels. I'm still using a Samsung S5 G900F
- And i finally got this fixed. it sounds like the reason for this is that since the latest update your phone cannot decide whether to use hardware or software back light settings. I managed to make the problem go away by doing this:
Go to settings >> system >> About device.
Find "Build number" and click 6 times fast on it.
You will then get the message saying: "You are now a developer"
and then go back to Settings >> system >> Now you will see the "Developer Options"
Now go to Developer options >> Drawing Section or Rendering Section >> Find "Turn off hardware overlays" or "disable hardware overlays" >> This will force the phone to always use GPU for screen adjustments. no more flickering.
but If I turn the brightness ALL the way down, it still flickers like crazy, however, if that's the only time it'll do it, I consider that a win.

Ghost touches

This is a pretty big issue that blue up on the OnePlus forum and Reddit. People are experiencing ghost touches in apps. It's very easy to also experience this by opening cpu-z and letting it sit there for a minute or two not doing anything. It seems not everyone is experiencing this though. I have tested and do experience it. Do you?

Yup. Mine does with cpu-z open. what do we do?

Depends if it's a hardware or software issue. Personally I already submitted a return request with OnePlus.

I just cancelled my order.. hopefully there is a software fix for you guys

This only happens to me on cpu-z and not in any other app. So I guess a future software update is gonna fix it.

Left it for a minute and didn't notice anything. On 9.5.3, bootloader unlocked and patched boot image with root.

I haven't experienced in a few days, it was happening a lot until I disabled pretty much all gestures.

I installed CPU-Z just to check on my International 8GB/256 model and I've got no issue with ghost touches. Not sure what is causing this for you all, but I do hope it is sorted out for you all.

When I turned off NFC the issue went away for me glad I don't use it whatsoever haha

Well that's not a solution disabling a useful feature to not have ghost touch issue.
On screen/off screen gesture are one of my favorite using it, so not a solution to me.
Simple will return the device.
I haven't order yet but i will next couple of days.
There's many reports across oneplus forum.

I left CPU-Z running for at least 10 mins.
And all is OK. Maybe it's a rouge program or something to do with the unlock\twrp?
The only way to be sure is to reset to stock and only install CPU-Z

Wow that's seems real bummer.
Why would OP use Novatek display controller since had bad reputation and bad track record.
So the question is how do we know if all that units effected having all of the them Novatek display controller?
Or if there's another supplier for those units that don't have that issue.
Man things are getting much worse if it's hardware related and not software that I thought.

It's extremely annoying it has happened to me a few times even when I was boasting about the new device to some colleagues at work. I thought it was me at first until then I read IRS an actual thing. I won't return it yet but I might if it's not sorted soon. It's extremely irritating.

Looks like ghost touches are related to NFC. Try with NFC turned off.

Can confirm. My Ghost touches seize when NFC is disabled.

I've started yesterday experiencing that ghost touchs and also screen not responsive to touch in some panel sections (mostly the upper right zone). The phone didn't gave me that problem since I bought. I noticed when this happening, pulling the notification bar down to the tile settings makes that zone work again. Same thing happened when that random ghost touchs happens.

Didn't had any problems, don't use NFC, tried turning it on, ghost touches started appearing on cpuz, but not on other apps. As i don't use NFC i probably won't return the phone.

I just tried with CPU-Z and a few seconds after starting the app, the screen turns crazy tapping here and there. Can confirm also disabling NFC solves it.

Turning off nfc or not using gestures or not using cpuz app is just temporary solution.
And there's multiple reports that ghost issues happening other app too.
And we never know if thing get worse over time.
I'm afraid it's a more common issue than we thought but many users simple didn't notice it until now.
Oneplus should clearly take attention on that issue seriously and fix it ASAP.
Shouldn't be happening at all with any kind app or scenario of usage.
