I love the n7...mostly. I want it to succeed
But the issues where the touchscreen will have dead zones / drop touch / not work properly are killing me!
Is this driving anyone else nuts? I have had two different ones, and they both have the problem.
I'm hopeful that either this will be a software fix, or that there will be a later hardware revision that I can rma for.
But man, this is a big problem!
Edit.....
Here is a post on the problem

ok, return and get a new one or demand a refund. I doubt no one here thought defects in a product were awesome, contact customer service
Are you not having these issues? I have had them on two different devices... Reports are starting to show up on the blogs.... I figured this was a device wide problem.

I'm holding two of them right now, no touch screen issues on either.

Im not having any issues either, but i havent played any tegra 3 specific games on it yet.
It only seems to happen sometimes... Particularly bad after playing intense games (dead trigger, e.g.).
Seems worse on the right side for me.
I in fact only took delivery of the 2nd one in the hopes that it wouldn't have the problem.

No issues here, played a few games and not a prob
Never seen any touch issues myself.
I had the issue this morning after powering up with the charger attached. The right hand side of the keyboard was very unresponsive. I was concerned the rooting I performed last night was contributing to the problem.
After powering off again it seemed to reset and has been working fine the rest of the day.
While it was unresponsive I downloaded a touch test app and it was struggling to see presses over 1/4 of the screen primarily the bottom right when in portrait orientation.
Thankfully it seems to be OK at present.

I've received much from xda-developers forum, so I wanted to give a little back.
My Nexus 7 8GB had the flicker issue and some screen separation on the left hand side, I contacted Google and did the RMA process, yesterday I received the new one, and the change in hardware has eliminated the flicker issue. I know many people are waiting, hoping it's a software fix (and there may be one), but there is definitely some hardware change that fixed the flickering.
The panel in the new Nexus 7 seems different, as the color temperature is significantly cooler than on my original Nexus 7.
I recorded a quick video, which shows them side by side, it's hard to tell unless you're running full screen and HD, but the flickering is visible. Hopefully this helps those waiting for a software fix not get stuck with a bad screen...
Other than the flickering problem, this tablet rocks!
Could you post your serial# and CSSN off the box?
Doesn't have to be your exact serial#...just a rough one. E.g., mine is 338Kish and it still has the flicker issue...
What makes you so sure there's been a hardware revision?
I have one of the first N7's shipped from Google, and it's flicker free.

Do you have the 8 or 16 gig version?

I'm not sure there's been a hardware revision at all... It could just be two batches of the panels, one faulty? Or something else. All I know is that one panel is distinctively warm in color (the original) and has the flicker issue, and the other panel is cool and with no flicker. Maybe just a bad batch of panels? Or some of the other accompanying driver hardware? Assembly?
I'm just saying that a hardware change made a major and distinct difference for me.
When I get a chance I'll post the CSSN/SN.

My dads Nexus 7 16gb has quite a yellow tint to the screen and the left side of the screen is sticking up - although I don't think it flickers.. He's getting a replacement tomorrow although it won't be directly from Google. (Tesco's)
I'll post up whether the screen is any different.
This is good info. Once we get more confirmation that perhaps a RMA will solve the issue, then we'll see how good Google is at doing exchanges from the Play store. This entire issue has been so hard to pin down.
It would be nice if Google was more proactive about it and just offered a solution, but that is wishful thinking, I know.
Thanks!
PS my SN on a 16GB model that demonstrates the flicker is:
SSN: C60KBC226---
I just got off the phone. Was on hold for all of 2 minutes. The whole phone call was 8 minutes and 18 seconds. Hopefully it all works out.
heh I did the map test too and saw flicker and planning my return, but I saw some other users were saying tegra devices had this problem. so I turned OFF the wifi, and there was still flickering!
so.. before anyone jumps to conclusions maybe try the map scroll with wifi off

I had wifi on for both of them in the video, brightness set to the lowest setting, and the auto brightness checkbox off. It was happening to me in all applications, the map just seemed the easiest to reproduce in, so it may actually be related to the wifi receiving/sending data.
The new one does not have the issue at all.
can you try them both with wifi off?
I just got around to trying to find this issue on my Nexus 7, and I do see that the Maps app has some "flicker" (i.e., color or brightness changes). If this is what everyone is talking about (sorry, haven't kept up with this particular issue), then let me say that the EXACT same thing happened on my Transformer Prime.
I remain pretty sure that this whole issue is related to the PRISM power-saving tech that's a part of the Tegra 3 platform. I've seen too many wonky issues like this on too many Tegra 3 tablet to think it's not related (that includes the Prime, the Toshiba Excite 10, and the Toshiba Excite 7.7, the latter of which is even an AMOLED screen and so not subject to LCD-type issues).
So I tried to reproduce the flicker on my N7 and was only able to reproduce flicker upon panning in google maps. When I drag the map around and the street names are loading I can sometimes see a minimal flicker (generally when I a lot of loading is occurring). Its pretty subtle and only visible when brightness levels are low.
Don't see any flickering at any brightness level besides that.
To OP, can you see any flickering at all upon panning in your new device? my N7 doesn't flicker like the old one you have, I could probably bare with it.
In a dark room with a Strong wifi full bars and barely and WiFi signal had the same Flickering issue with google maps. It is something else.
So for me it doesn't appear WiFi signal effects it.
Going to be calling Google tomorrow.

The change in colour temp is probably just normal variation. No mobile devices are calibrated (including the iPad3) and they all show a fairly wide variety in their white balance. It is possible, though, that the flicker has some sort of causal relationship with the screen lift.
My search led me here after noticing the flicker issue while browsing the web on my n7 at night.
I just did the map test and it flickers every 5 secs with the WiFi ON. With WiFi OFF there is no flicker. Same with all the apps that use WiFi.
So is a this a HW or SW issue?
There's already a large thread on screen flicker. Not sure why we needed another. Maybe a mod can merge them.

Thanks for the post. I received mine on Tuesday and noticed the screen flicker with the auto brightness. Called last night and they're sending me another. If the RMA flickers, I'll wait until Google's new Motorola division begins creating actual PURE Google products.
Here's my Nexus serial: xx0KBC019770
My first device had the screen separation issue. I have since had this replaced and the new one has the screen flicker.
It is most noticable when the brightness is at its lowest, above 20% it _almost_ disappears. turning wifi off seems to stop the flicker.
In the video did you have the brightness the same on both?
I bought the Z1s about 2 days ago and have since then noticed that there is a column of pixels that appear faint going down the mid-left side of the screen. It can only be seen in very high brightness setting and is easier to spot on top of grays. Also I have the erratic touch issue i've been reading about where the screen doesn't properly register a continuous touch. Is it worth starting an exchange chain with tmobile or am i just more likely to get the same or more defects on subsequent phones?

I'm absolutely sure a malfunctioning column of pixels is a definite reason to exchange but I've read that the erratic touch responsiveness of the screen is a common issue with Z1 owners. Just out of curiosity, do you have any such issue?

Yes, I had that issue and I sent back to repair mine but they didn't fine such a issue and they scratched my phone everywhere. I solved after the FW .136 fixed the problem and I don't see the issue anymore. Sometime seem like it losing the touch but slightly. No problem at all when I gaming.

I think everyone has that issue. Especially if you took off the ASF. It happens on mine sometimes, but just turning off and on the screen fixes it.
Has anyone seen this issue after the update? There is a little notch in the bottom right of my screen. My wife's Pixel 4xl is not doing this. apologize If this is something that im not familiar with
Nope. Mine is fine. That's definitely a hardware related problem
Confirmation of above, no such issue.
Looks like a defect to me, get it exchanged
Had the same issue with my Pixel 3. Oled hardware defect.
Got it exchanged.
It's a shame this kind of issue still exists in the 4xl.
Hello there (General Kenobi)
Just got my brand new Galaxy S20 FE 5G a few days ago but I'm experiencing the touch screen issue. My phone is up to date but I still have the problem. When I have to scroll, the screen doesn't respond at all or thinks it's a tap on the screen and it suddenly goes crazy.
It does only occur on the bottom part of the screen after I unlock my phone from a long period of non use.
I contacted Samsung and they told me to get it to a repair center. But I don't know if this will work and I'm a bit scared that getting it to the center would make things worse.
I saw that Samsung already rolled 3 updates out to fix this problem but I'm still not sure if it is a hardware or a software problem.
Did you guys face this issue? Do you think it is a hardware problem and I should repair it?
It is a good phone and after having left the Pixels because of hardware problem I'm annoyed
*WELL hello there
I get the occasional unwanted zoom in a browser or failure to respond to touch, what you're describing sounds worse than the multitouch issue others have been reporting.
I'd give serious consideration to returning that phone for a replacement or refund. the current reckoning around here seems to be that this phone got a digitizer from a cheaper price range compared to other S20s. what you describe sounds like a faulty digitizer.
is putting up with it for a couple of years not going to bug the crap out of you ?
if they offer only to repair it, accept only a new screen / digitizer / glass swap out.

About the famous multi-touch problem I have to admit that I tried to reproduce it but it only appeared when I was using 5 fingers (instead of 2 in the videos I saw)
I think you're right and I should get it repaired. And I'll see after that if the problem is still here I'll ask for a replacement. I will post an update as soon as I get it back
Thank you!
If you don't mind, could you let us know your phone's hardware revision number? An app called Phone Info *SAM* can show it. People would be interested to know if Samsung has made any hardware changes to the FE line.
Okay guys I'm sorry I couldn't reply before. I had to sent my phone for a repair THREE TIMES ! The first time they didn't do anything but damaged the back of my phone (replacing the screen and the battery) and the problem was still here. The second time they sent my phone back with the battery literally filled (the back of the phone was also damaged due to the battery that had filled).
I got my phone back on last Friday. Seems to be OK. They told me they couldn't reproduce the problem. They just repaired what they did wrong but didn't seem to do anything with the touchscreen.
The phone looks OK. After 1 day of use, the touchscreen seems to be OK but I would like to wait a bit before adding [FIXED] to the title of the topic
Does anyone know if the 2021 version of FE the 4G Snapdragon (g780g I think) has the same problems with ghost touches and jittery scrolling? Can't find info on that anywhere. Deciding between the FE and 8T, but the risk of bad touchscreen is driving me away from it although it's better phone.

I'm sorry I couldn't tell you. I bought my phone around February and it has the problem. This is the 5G variant with Snapdragon 865. I didn't even know there was a 4G variant with Snapdragon (in France, it's either 4G/Exynos or 5G/Snapdragon).
The phone is great though and now my problem seems to be fixed I'm keeping my S20FE over the Pixel 5 even though I'm a Pixel fan.

actually it looks like that's the only issue he didn't have.
That all sounds like an Exynoss version He might be wrong, maybe it is Exy?
Haha I don't feel concerned about the problems that he had because coming from a Pixel 5 some of the problems he had was worse on the P5 (reception, sound quality and the fact that the device can get warm)
