[Q] Does anyone have dead spots in their touch screen? - Nexus 7 (2013) Q&A

I have the Nexus 7 FHD 32gb model, and as of late my patience for the device has been wearing thin. There seem to be strange responses to the touch screen where certain zones have no response, or some times the touch and hold gesture glitches and upon lifting my finger the screen will respond as if I'm still holding my finger down. I also enjoy drawing with my new tablet, but here lies a problem as well. The problem seems to only be persistent when in vertical orientation, upon switching to horizontal the screen seems to respond slightly better but still misses a few finger taps here and there. I'm on the newest OTA available, have little problems beyond that. If possible, can this be resolved via software? I do have knowledge of rooting, and if the required fix for the time being is to run a custom rom so be it.
Thanks in advance

Just decided to finally root my tablet and install a good old favorite Paranoid Android, hopefully there are noticeably good changes!

There's a thread here with a fix for some devices. By sfnub I believe. Mine does the same.

[Q] Screen sensitivity Issues??!!

I noticed an issue with the screen of the galaxy nexus.
-It seems that it does not regester the touch of my finger as good as my nexus s. " once you touch the nexus s screen very lightly you see a direct response. In the GN the light touches does not regester. Is that normal??
-Another way to test for it is using a stylus... the nexus s works perfectly with the stylus touch. In the GN you have to push slightly for the touch to register.
Finally.. when touching the keyboard very slowly... the button does not register no matter how hard you press. weird!
Have any one noticed this issue?

This simply scientifically doesn't make sense. If the nexus was a resistive touchscreen you would have to push hard, but, it's not. On a capacitive touchscreen it picks up the electrons in your finger, so, the lightest touch registers. It is impossible that pushing harder works better, that's not how the screen works. This is the case on the GPS in your car, not on your phone. It's probably your messed up brain ha ha jk

I know what I'm talking about!!. what I meant is: you need a larger surface area of your finger to touch the screen for it to register the touch.
there is a significant sensitivity difference between the GN & the nexus s
Here is a quick video demonstrating that slow touches does not register:
http://youtu.be/3a8rMJvI7zs
Personally, my nexus allows me to barely touch the screen to register. BUT, in past experience with capacitive screens, when my fingers were particularly dry the screen wouldn't register unless I put more finger surface down. I do a lot of wood working and all the saw dust really sucks the moisture out. Now, whether its the lack of moisture, or the capacitance between my dry static-y finger and the screen surface making mini lightening bolts, I don't know, but there was a big difference

This could be due to the fact your not holding the phone in your hand while interacting with the touchscreen, on nexus ones the touch screen/capactive buttons didn't work too well when the phone was placed on a desk and interacted with.

I have seen the same issue as the op, it is especially noticeable on the system soft keys where they require more finger surface area before they register the touch. The worst offender is the three dot menu key in the soft key area.
Hope they tweak the screen sensitivity a bit.

It also happens when I'm holding the device in my hand. I noticed that the lower screen is less sensitive than the upper part.
me too can confirm this issue.... it's like in the posted video:
trying to touch the screen on the Gnex sooooo slowly/lightly some times the screen don't take the input
you can verify in dev setting on the option that show you touch screen coordinate when you touch.... on the bottom of the screen you can see 'PRS' value (pression): try to touch so light you can the screen, you will never see number lower than 0,26/0,27 values.... now, if you can, try out on nexus s on other phone you have... you will see a very lower number. Lower is the number, better is the touchscreen sensibility.
and..... i know the difference beetwin capacitive and resistive touch..... soo, why can appen this issue to a capacitive one!?!?
p.s. i think this could be a software/driver isseu..... then could bee adjusted by a dev
there is app usefull for this problem, but only for Gnote/Gtab and transformer:

i think some dev can look into this and make one app for galaxy nexus too
can i make....?
Up! XD
To add to this. Overall theGnex touch screen is excellent. The driver seems to be configured to reject touches that are under a certain level of "distinction". If you slowly touch the screen and slowly spread the area of your finger skin over the screen, the touch is rejected. Generally it has stopped some inadvertant brushes, however if using the phone in bed holding it with one hand, it can be hard to use the touch since it can be hard in certain positions to be a bit "snappy" with your touch. It definitely seems intended.
yes.... thanks for the reply
i hope some dev can look into the driver and increase a little bit the screen sensibility.... as you had spoke, on the bed it's harder use the softkey.... and when i put my gnex in cardock it's the same....
you can try this app too it can change the sensitivity, minimum motion and duration to register touch. i have it installed and it does make the touchscreen quicker and more accurate for me. Need root for this one.

it seems only for samsung galaxy S....
yes but it's reported to work for the galaxy nexus as well. im using it with my nexus.
I posted this in franco's thread but it didn't receive a response.
http://forum.xda-developers.com/show....php?t=1559015
It seems you can edit the touch screen driver in the kernel for the Galaxy S2 and improve the sensitivity.
It has to be some sort of setting to ignore slow touches.
We have to find the equivalent driver code for the nexus. But definitely interested in this, looks like the solution we need.
Noticed this on my Galaxy Nexus as well. Thanks for the confirmation
did anyone find a solution to this problem? I tried the SGS Screen Booster app and i still can't get some touches to register. (i.e., the App doesn't seem to make a difference)
R: [Q] Screen sensitivity Issues??!!
Yeah i can confirm this!
My Nexus is D1 production (jan 2013) and i noted that in general bottom part is less sensitive than upper part!! Quite obvious in the corners and the nav bar. It is not linked to accidentally hit buttons, because you can try to rotate and that part will always be less sensitive.
Even in the upper part, my s2 is far more sensitive than this!
I hope it can be tweaked via software, but I smell crappy hardware here (Samsung Samsung....) because I already returned two devices.
Now that i know someone else noted it, I feel less crazy

3 phones within 1 month..lol

First nexus had a charging port issue...Verizon sent me a refurbished one..Second phone had the lower section of screen sunk in and soft keys not responding to touch...third phone received today wouldn't call out or take calls but data was working..went straight to where i bought it tried 2 new sim cards level 2 tech support with employee......to find out if you go through 3 phones you can receive a new one that's what they did for me.....how can Verizon send these refurbished phones out when there supposed to meet regulations a pass a certain requirement before releasing these?...wow

Wow. Sorry to hear that. Thankfully mine appears to be working great and no sunken screen here.

Could you elaborate more on the "sunken screen" problem?
The soft keys on my Nexus doesn't seem to be responding too well. Turning on the "Show touches" under developer options indicate that the touch area of the screen where the soft keys are is not as accurate as the rest of the screen.
Thank you.
i know..i had Motorola Droid,Droid x,and x2...then just went Samsung i waited for this phone for months...this phone is the best i think....its the Verizon inspection dept that stinks releasing phones not being fully inspected and tested..lol...

If you go to developer options and click on show touches, you can see that the touch response near the bottom edge of the screen (where the softkeys are) is less as accurate as the response on the other parts of the screen. This is not a software issue related to the softkeys because if you go to the browser and rotate so that the softkeys are near the earpiece, the same inaccurate response issue can be seen.
Anyone else have this problem?
To me the sensitivity on the soft keys seems a little less responsiveness ..i was playing around with the apps that show sensitivity on press and touch locations seems to me there not the same from the soft key area and right above it..or is it just me?.......

The second phone i received from Verizon was refurbished the screen was not flush with the case almost as if the screen was sunken in more then the top half..i should have been more specific ..they took it back though..so. i was happy

You see this only on your third device? For me, the touchscreen is less sensitive when it is close to the edge of the screen (near soft key area).
I wonder if i have a faulty device or if that's the way the hardware was implemented

Help, screen issues

So ive had my g2 about two years now, its got is scratches and what not, but for the most part it functions well.
The largest issue is that sometimes when using the touch screen when i pull my finger away that area will stay activated like my finger is there. Happens a lot when using the on screen keyboard, and it seems to be getting a little worse.
Sometimes a good cleaning helps, but before long it comes back.
Anyone have the same experience, or able to recommend a fix.
Was thinking of doing a digitizer/screen replacement but figured id see if there were any experienced suggestions.
Thanks in advance!

since my phone is new I have this ''issue''.
I got it on the motorola milestone also.
But for me, the problem appear when I have sweaty hand ( stress or too much cofee). It looks like if I still press a key even if my finger is off.
My brother had the same problem on is galaxy SII , he put a plastic film (protective glass) and the problem is gone.
In inverse, if my fingers are too dry, the screen has difficulty to respond.
My solutions : wash my hans often, dont drink coffee, dont stress and wipe the screen on my jeans.
Thread moved to Q & A section, post in the relevant section next time.

Anyone else having this shaking issue with the screen? Happens with finger, not spen

Whenever there's a webpage or app where I can scroll, if I start to move my finger up (or down) and then stop, the screen starts to shake. It gets really annoying after a while.
When I use the s pen, this does not happen. Everything is nice, smooth, and just great.
But when I use finger, I get the shaking.
Anyone else experienced this? It only shakes like 2-3mm up and down but it gets annoying..
I've never had such issues on any of my other devices: LG G2, Droid Razr, and iPad (my mom's)
Yup this is an issue with plenty of people. I'm sending mine in for repair in a day or 2 for this problem. If they can't fix it, I don't want it back. Supposedly there are those who don't have this shaking crap, so maybe if they just replace the tablet with a normal one, I'll be happy. That's another thread on here with more info and more people experiencing this. Multi touch problems, basically. Who knows. I'm planning on updating the status of my note over there once I hear back from the repair center.
It's a software problem, Al, out everyone with this tablet has this problem

I never noticed this, because usually I put my finger off the screen after scrolling. But you're right, I tried it by scrolling then stop and keeping the finger in position. The screen starts to shake or more like to vibrate up and down.
But to be honest, I don't care, as I won't experience this in my normal usage.
None here ..

[Q] Touch screen sensitivity problem

My touch screen is too sensitive. Sometimes it "presses" itself alone but if I clean the whole screen it gets better for a while. Now i have tried a multi touch tester app and I couldn't make it to recognize more than 5 fingers. To be honest it drops all touches on the third one but the app shows it got five different touches. I've tested it on my htc one and I could press it by all my 10 fingers.
What am i supposed todo? Take it back to the store? Buy a screen protector what makes it less sensitive? How about yours? I even tried the calibration.ini method suggested on other forums.
It is worth trying a screen protector. I am not seeing the same issues but I do have one on mine.
