Touch sensitivity - Nexus 4 Q&A, Help & Troubleshooting

Since Nexus 4 has been released one thing is key problem of this phone is touch sensitivity.
So anyone knows how to fix it or is that a hardware problem.:thumbup:
Thank you

If you take a look in the Original Android Development section, you'll see that there are kernels that claim to fix it. You could always try flashing one of those. I never had any problems with the touch sensitivity anyway. Yes, the screen's a little less sensitive than my Galaxy S's screen, but it's only a minor difference. It didn't even take any getting used to.

Defect Question: Touchscreen Jumpiness

Hey everyone,
I have an issue with my tablet that I'd like to confirm is a hardware defect, if others have seen a similar issue, or if what I'm seeing is really a defect at all.
When I use the full pad of my thumb or index finger on the touchscreen, the touchscreen doesn't seem to recognize there's only one touch input on the screen (or one touch input staying in one place). Check out the video I took of it:
Does the problem happen when you've got a finger touching the headphone jack? If not, this is a known grounding problem. More info in the topic about "crossing axis" in the discussion forum.

This is a known problem and nexus 7 does this when one use his whole thumb. Mine also do the same and I have discussed it many people here before and people have most confirm to have this issue. Some people fail to accept that their device has faults so they just say no to anything.

Agreed. I can confirm this issue as well and it's likely to exist in all devices.
Thanks, everyone. Bit of a shame since it's such a high quality tablet otherwise.
Asking a mod to close the thread. I'll follow the 'crossing axis' thread instead.

Nexus 7 LCD question

This question was triggered in regard to the folks out there (myself included) who have experienced cracked SCREENS in the early models. I'm curious, what is it about the design of the n7 LCD that causes all touch functionality to stop if a crack occurs? I remember seeing touch screen devices in the past with cracked screens that still responded to touch... Just made me wonder what made the n7 different. Then again maybe it's not so different and I just haven't come across anybody who had a touch-working cracked LCD... Any insight?

according to my personal knowledge, the touch sensors are built into the display itself, or if you prefer, the glass. so if the glass does shatter, this is a fair chance that the touch sensor will be damaged.

[Q] Anyone also having the Nexus 7 "touching itself"?

So just this morning, something wierd occurred with my Nexus 7. It seems that another finger or the nexus 7 touching itself. I manage to restart the device and it seems to be ok (for now).
So I turned on the "visual feedback for touches" in the Developer options and this is the result (quick video)

Does anyone also have this issue?
I've had this issue, cleaning the screen fixes it for me.

I was lured here by a kinky sounding title. That's messed up though, is the screen lifting on any side?

LOL. I do have a slight screen lifting on the left side when held in portrait but its not worse(It is somehow fine with me) compared to the others.
Tried cleaning the screen(Thanks to neonghost) and it seems to work properly now... so far.
try a different kernel.. i was reading that one of them had that issue.. started with an M i forgot the name.
I have it and it seems to be related to screen lifting as I've found holding it on the left side causes ghost touches. The left side is the same one which is prone to screen lift of course. My unit has zero screen lift but it seems there may still be too much pressure or something on that one side.

That would be motley or metallice.
But it wasn't their Kernels causing it, it was Clemsyns (however its spelt) which was stock but underclocked.
Seemed the underclocking was too severe.
But yeah can also be a dirty screen.
Thanks for the into. I do use a custom room and kernel. And i have a very slight screen lift which i can ignore.
And yeah the pressure theory you have might be plausible as i do hold the nexus on the left hand corner when in portrait.
As of the moment cleaning the screen solved the issue for now. I'll look into your suggestions once it occurs again.
I think your nexus is HAUNTED!! Could be the "ghosts in the machine" that they talked about on iRobot. This is an OS called android after all.

The nexus 4 has the worst build quality I've ever seen

I don't care what anyone says. The nexus 4 is a really cheaply made device. But what can you expect from a device with good specs at that pricepoint? Answer: a lot more than what I got, that's for sure. Anyways I have a huge list of defects on mine, so I hope I can cover all of them here
Screen banding: greys look quite poor and inconsistent, almost like the ribbon cable is damaged. Similar to this issue is that after turning the device off for a few minutes then turning it back on the sides of the screen, especially the right side, look way brighter than they should. Almost like backlight bleed, which I have as well
creaking: An issue mostly for the nexus 7 that somehow arrived on my nexus 4 as well. My nexus 4 for the longest time creaked like you wouldn't believe. You know when you pick up an old SNES controller and twist it a bit and it creaks? Yeah, like that, except it was every time I touched near the power button. I tried to fix it, but I only caused 2 other areas to creak and only partially fixed the first one
multi touch issues: Another issue thought to be exclusive to the nexus 7 but was transferred over to my 4. I first noticed it when I was fooling around with an ocarina app on my phone and I couldn't cover all the holes, so I downloaded a multitouch app and noticed a problem. When I have 4 fingers touching the screen, one of a few things happens. It either only registers 2 or 3 touches, or if I move my finger it will move the finger that I have parallel to it the opposite direction that I moved my finger. And if I have them all in a line it just goes f*cking nuts, sometimes having one finger, sometimes having 4 but not in a straight line, sometimes 2, etc. It was even worse than my nexus 7.
I could go on and on about how there's a dead pixel somewhere on the screen, or how there's sometimes a green spot in the middle of my camera, but let's stop there. You may be wondering why I haven't returned it yet. Well that's because the glass on the back completely shattered, like spiderwebs everywhere. But I didn't drop it, nor did I put the hot phone on a cold table, in fact, I just squeezed the side a bit. I took off the cover to fix the creaking issue, since I figured out how to fix it, and I wasn't pushing that hard, I've put far more stress on it just from taking it off, and I hear a loud "pop" and my hand is covered in glass, and there's really bad crackage on the back. I also put a tiny crack in it earlier from letting it slide off of my pants TWO INCHES OFF THE GROUND. *heavy breathing* I've never had such poor experiences with devices in my entire life. It's even worse than my experience with my nexus 7, which had similar issues, like the creaking, and the backlight bleeding, and the multitouch issues, and my nexus 7 had at least 40 stuck pixels on it that weren't fixed when I got a new screen. I don't think I'm ever going to buy a Nexus product ever again. I don't care if it's stock android, or if the performance is good, or if it's easy to root, or whatever. What's the most important part of a device? Being able to f*cking use it. And I can't use any of the devices I've owned because they've all been defective! My galaxy nexus had HUGE scratches on it just from it being in my bag, and stopped charging even after replacing the USB port, my first nexus 7's battery didn't work, my second nexus 7's screen had at least 40 stuck pixels, the oleophobic layer started to come off and it creaked a bit, and after getting it RMA'ed most of the pixels were still there and it creaked like a SOAB, and my nexus 4, I've already explained in depth. So now whenever I hear "oh, the nexus 4's build quality is comparable to the iPhone 5" or "the nexus 7 is soo much better built than samsung tablets" I just chuckle and say "yeah, I believe you"
What do you expect it sells for 299$only

Sounds like more of an issue of how you take care of your devices rather than the device itself.
I have every device you listed and they look brand new while never using a case.

I took superb care of it, the vast majority of issues I have with it were there when I got it, and sorry put it in the wrong thread.
My phone is in really good condition. I bought it on launch date and I have not had a replacement get. I really don't know what you are talking about.

Well that was a poorly-formatted paragraph, and after sifting through it for your complaints, I can tell you that half of those issues can be "fixed" with kernel adjustments. I put 'fixed' in quotation marks because they aren't really fixes, more like tweaks.
As for the rest of your complaints, it seems like you don't take very good care of your phone. My Nexus 4 is in mint condition and I don't use a case or screen protector. If it's not in my hand, it's in my pocket. I don't set it on tables or anywhere, really. Treat that phone like the high-end piece of electronics that it is instead of the way you treat your car keys.
Also: prepare for this thread to be closed.
Idk man it sounds a lot like ur just complaining .. I've had a lot of devices so little stuff doesn't get me anymore but you could've gotten unlucky too but honestly I've had my phone since November and I just haven't tried to hear it creak . .I'm sure it does but I could care less you might have OCD though if ur noticing all that small stuff you might wanna get that checked out.
And the other stuff sounds like u did it ur self cause that first crack is always the hardest after that ur screens pretty much shattered honestly

I don't have any issues with build quality mime is great!! Flash a kernel to make the colors great!! If you don't really can't what people tell you about the build quality what post this when you know people are going to reply.
Sent from my Nexus 4 using xda premium
You're judging the build quality of a device sold globally based solely on one defective unit that you happened to receive? That's simply not logical. I for one have a device with no issues and I consistently throw my phone onto my bed (easy 2-3 feet down) and absolutely nothing has happened to it. I can get a creak but only if I press the back of the phone with amounts of force that would never come up in a normal usage scenario. You're hugely exaggerating here, and while I understand your frustration there's really no point complaining about bad luck.
You don't care what anyone says and nobody cares what you say. Let's call it even and move on.

Well I'm glad to know that other people are having better luck. And I already said I take superb care of it. I don't throw it around, or whatever. I treat it really well. I'm just really frustrated that I always have such bad luck with things like this. I'm just gonna remove this thread as it's not doing anything productive, nor is it necessarily an accurate opinion.

Yeah I apologize this thread really shouldn't exist. I just got a bit angry and didn't know where else to put my anger into. The nexus 4 is really a fantastic device, just not MY nexus 4. Besides I'm getting a new back which will fix the creaking issue and cracked back issue which are the two issues that bother me the most. The rest of the issues are fairly minor (except maybe multi touch, but who knows, that could be the back as well, maybe it's a software bug) and I can live with them. I've already calibrated the display so the banding and bleeding issues are a bit less pronounced.
I tested this multitouch thing:
I can place all my 10 fingers on the screen and it will recognize them. But put 4 on it and place them in a line: every "touch" will be gone ..now move one finger (while 4 are on the screen): 1 finger is recognized.
Yes, very strange.
I too have slight creaks on the screws and a bit on the power button. And a lot of small scratches on the back since it just lays on the glass :/
How often does someone need to use their screen like a retard unless u have no fingers
I really shouldn't be complaining too much because it could be much worse. And it only cost 350 dollars.
I don't care what op says. My n4 is the best phone I ever had. And mine build quality is iphone like. I had to rma my first one due to some problem. But rma process is too easy smooth and fast not like iphone.

At least you realised and admitted this rather than doing what some people do and arguing fruitlessly. If you want this thread to be deleted or closed report the OP for 'maintenance' and ask for it to be closed, or PM a mod.

Exchanging the Nexus 7 Twice?

Hey all,
I bought the Nexus 7 from Best Buy on release day. The first one I got had banding issues (so I thought) but it turns out where I was seeing it in the settings is common and has to do with the background used from what I found out after I exchanged it. The one I got now has bad backlight bleed and the screen seems blurry. Not sure what's up with that.
My question is, will Best Buy care if I go exchange the device again? I'd rather not be stuck with an actual defective one. Thanks!

I'm about to return mine and wait until they get more in stock, the screen on my Nexus 7 32GB is sometimes not recognizing my touches , sometimes have to press really hard on the screen just for it to recognize, and even then it isn't 100% accurate.
Something is off with the touch sensitivity tuning. I remember reading that 4.3 brought increased sensitivity to the N4, maybe the N7 is starting out extra sensitive. I've noticed it most with the default keyboard. It sometimes double types a single character. What's happening is that it recognizes my finger before I actually hit the glass, and then again when I hit it. But this should be fixable with an update.
I wish android would allow touch sensitivity user customization, something like on Nokia's Lumia WP8 phones.

I exchanged mine today for this exact issue and the new one has the same problem. Wonder if this can be fixed with an update?

I'm unsure about the touchscreen issues. That typically results from bad connections or somewhere. Have you tried Yet Another multi touch App?
It has 2 functions, one tests inputs the other is like a paint. I recommend trying to color the entire screen. This will tell you if you have any dead spots.
If your touchscreen isn't working well I highly recommend you swap it out. What good is a tablet if the problem gets worse?

I'm having the exact same problem with the keyboard... while typing, i would get rapid taps and some letters would show up 3 or 4 times. just wondering if this is a hardware issue or software issue?
If its a software issue, i can wait it out... but if its hardware.. i'll go and exchange it for a new one.
