Hello,
I just noticed a couple of days ago that a section of my screen has become slighly unresponsive. It appears to be intermittent, and Swype in Landscape mode is primarily affected.
In landscape mode, keys m, j, and u are not responding. During shutdown as well, the power off confirmation both yes and no button locations are unresponsive.
These areas of the screen are responsive usually, except during power off confirmation and using Swype. Could this be a software issue?
Does anyone know what might be the cause, or how to fix it?
I have not yet tried any fixes, though I may just restore using a backup ROM I made shortly after I rooted my device. If that doesn't work... then :|
EDIT: This appears to have started shortly after I installed LauncherPro, or it may have also occurred since I removed all pre-loaded Google Apps to replace with the newest versions off the Market. :\
EDIT 2: Restored my ROM, m key has regained some responsiveness, other keys no good. Using Swype, the line goes near them, and then just breaks, sometimes. Other times, if I swype really fast, I can passover and include the key, but cannot swype up vertically among them. Unable to press them directly either.
Switch to Android keyboard and things seem to be ok again... fully responsive... this is weird.
EDIT 3: Crap... one row in the middle seems to be affected... somewhat. Downloaded a drawing app, and this one row doesn't want to play nice. It responds properly in most instances, yet there definitely seems to be a problem.
EDIT 4: Appears that a section of my screen is non-responsive. A whole row. Argh. When I move shortcuts, passing nearby this 'dead row' the icons jump. In swype, it acts like an invisible barrier, either I move really fast and it sorta jumps across that key, or I move really slow, and it's like my finger is lifted off the screen. Android appears to be compensating heavily for the non-responsive section and guessing my inputs. Tapping in this area still appears to be somewhat responsive, dragging or swiping across this area is producing very mix to bad results.
I need to have the touchscreen/digitizer replaced, right? The LCD panel appears to have no issue. Argh. Could it be due to the InvisibleShield I put on top?
I had a similar problem with my G2. I tried putting one of the Zagg protective covers on it and immediately afterwards the touchscreen would not respond properly. I would have dead spots on top right of screen and bottom left. At first I thought it might have been from the solution seeping into the phone, but I think I might have used too much pressure and damaged the digitizer. I ordered one earlier this week and will update you with my results.
The screen is capacitive... which means that your finger completes an ELECTRICAL CIRCUIT. If your screen protector is blocking current at all, this will manifest as a loss of sensitivity.
The second thing to understand is that you can't just touch the screen with your finger to complete the circuit, the other end of the circuit has to be completed as well. The metal ring around the screen is the other side of the circuit! You need to be touching that metal ring in order for it to work properly. Even with the phone just resting on your hand, you may not be contacting the ring and may experience a loss of sensitivity. In portrait mode, try clamping your fingers around the back of the phone to contact the ring on the far side. In landscape mode, use your index fingers to touch the top part of the ring.
If these suggestions don't help (including removing the screen protector), then you most likely have a bad digitizer. Check the ribbon wires to make sure that they haven't pulled out at all before replacing.
Just replaced my digitizer and it works great now.

I've just discovered that my gyro sensor doesn't work. I am running rooted stock 4.1.1. The phone can not detect tilt movements. And under Settings->Motion->Sensitivity settings->Gyroscope calibration, the blue dot does not move from the center, no matter which orientation the phone is held. All of the options under Motion don't seem to work. I just want to see if anybody else has the same problem before calling TMobile.
Firstly, this should have been posted in the q&a section.
And the blue circle isn't supposed to move. You lay the phone on a flat surface and it calibrates itself.

Sorry for posting in the wrong section. You are right about the blue dot not moving. I downloaded a few apps that detect sensors and all built-in sensor seem to be working as they are supposed too. I have problem for example of taking screenshot with a palm wipe or zooming picture by tilting the device, muting phone by turning it over, etc. None of these features work on my phone. Will try to explore more to see what the real problem is.

Do you have the switch turned on next to motion in the settings?

Before you go off the deep end, run the test on the sensor.
in the stock dialer:
Quick Test Menu
*#7353#
select the accelerometer tester and ilt the phone whatever way you want. If the arrows don't change, then the sensor isn't working. If the Arrows do change, then all good, no panic necessary...
Good Luck
Aloha
Thank you for your help. I ran the sensor test and the sensors work. I also turned on the Motion switch but the Motion features still don't work for me. Maybe this is a software issue. I will continue to explore and will report back if I've found something.

Hi,
Please do the following:
Pull the top notification bar down by using a downward swipe.
Tap on the Toothed Wheel in upper right corner
scroll down till you see the System divider (below the Add account line)
is Motion ON on the right side of it? if not, turn it on.
Tap on the word Motion
Are any of the options you want to use set with a check in the box?
if not, put the check in whatever you want to use by tapping on the box on the right of the function.
Example:
If you want to use Palm swipe for screen captures, tap on the box on the right of the option.
the boxes toggle these options so if you want the option off, then tap on the checkmark and it'll go off.
When you're done, click on the back button on the right side of the menu bar below the screen till you get back to the homescreen.
You are done, and the selected options should now function.
simple huh?
Thank you, bobolinko. I've been doing exactly what you described and no motion feature works for me. I begin to think that my software has a problem, because it does crash occasionally and software upgrade check hangs forever in the "checking for software updates..." screen and never comes back, no matter if I am on wifi or on 4G. Let me reinstall stock firmware and report back.
Try it like this:

Also, has it EVER worked?
Thanks!

Thanks for the video. I did exactly as shown and nothing happens. I never tried Motion before until I needed to capture my screen and discovered that it doesn't work for me. In the mean time, using PWR and HOME button at the same time does allow me to capture the screen, so I don't really need Motion feature working for me. I am just thinking that my software has a problem and I will need to reinstall stock. Thanks a lot for your help in any case.

im having the same issue. tried the accelerometer test and tilt the phone every which way but the arror didnt move at all. does that mean the accelerometer is done with. any fix for it?
also tried tsp dot mode, tsp grid mode, proximity and light sensors and nothing seems to happen during the test
Hello.
i imported a nexus 7 tablet from a local market because its still not officialy available here yet. anyway everything is fine except when i want to move an icon to the right page or anything that come close to the right edge of the screen.
i tried to use a drawer app to see what is the problem, it seems when i draw a line from left to right, the line stops just before it reach the right edge of the screen. now if i only draw a vertical line on the right edge, it will work. so i am not sure what is the issue when i swipe/draw a line / move an icon from left to the right edge.
i then tried the mutli touch test program, it detects my fingers on the edge of the screen however, i find it very point of the screen is jettry ? like it shakes as if its not detecting a single pixel and detecting the one beside it.
i duno do i have a dude or they are all like that

Try the touch screen fix if your device is rooted and you know the basics of tinkering!

I noticed after upgrading to Lollipop that it was difficult to navigate menus near the top of the screen in some apps. I turned on the "pointer location" option and sure enough I found very strange results.
i.imgur com/tPdVowo.png (you'll have to add a period after the domain name, new user status prevents me from posting links)
This first screenshot is me running two fingers all the way to the top of the screen, and once i reached the top i ran them towards the edge of the screen. As you can see there is an area where the pointer location bugs out.
i.imgur com/bh5hWeV.png
This image is just a single finger running horizontally across the top of the screen. The top line is where my finger actually was, but the phone also registered extra touches as you can see from the line below. There's even a section where the top line didn't register at all.
This is a Verizon phone, never been rooted, and hasn't been dropped or wet. I noticed while making this post that the area i am having issues with aligns almost perfectly with the top part of Sense's notification menu.
Is this normal or do I need to exchange my phone?
I am having the same issue with my phone. When I turn on show touches in developer options or install a multitouch test app, it'll show an extra touch just below where I'm touching but only when I'm touching at the top of the screen. Stock lollipop, never rooted, no water damage.

same problem. do you have s-off? downgrade firmware and rom - maybe this fix problem?

I don't. I didn't want to do that yet. Was hoping to see if anyone else had the issue and if they were able to resolve it.
Just want to see if anyone was able to resolve this issue.
fixed!
we need the old piezo lighter's element. The phone must be turned off. A few strokes on the screen near the problem area, and voila, the screen works again. Do not be afraid, the phone will not be damaged

So, last week I bought the P2. So far I'm very pleased with the device. Next to the known audio sync issue I ran into one other thing that still bugs me after a week of use: the bottom edge of the touch screen doesn't seem to respond to touch. When I slowly slide my finger from above the screen over the edge of the screen, it immediately picks up my finger, even when only a small part (maybe a millimeter) touches the screen. When I do the same thing at the bottom of the screen, it will only start registering my touch when I'm about 6mm in.
6mm doesn't sound like a lot, but it's enough to make me miss-touch the space bar half of the time. I thought I'd get used to it, but it is still quite annoying... Is this the same for all P2's? I'd like to hear if anyone can confirm this.

Same problem here, it seems that when you hide the on-screen buttons that area is effectively useless. On 6.0.0 and 6.0.1. I have no idea how to fix, but you definitely aren't the only one
i too had experienced same problem, while playing Asphalt extreme, it doesnt let me press the NEXT button
Well, I'm glad that my phone isn't broken. Let's hope it's a firmware issue and not a hardware one!
Check your keyboard set up. I have hidden buttons and the whole Spacebar is active to touch. Right to the bottom of the visible Spacebar. There is a gap slightly narrower than the Spacebar beneath it at bottom of screen. This does not respond to touch. My advice would be to be a little more accurate with typing . As there is no way to fix this and keep hidden buttons. Gesture home button, hidden navigation buttons and big battery are best features of this phone!
I wouldn't even have noticed this issues if you hadn't pointed it out. It's present, but it doesn't really bother me too much. Especially since I switched from my G4 which had me miss the spacebar and hit the home button way too often lately for no particular reason. Not having those softkeys is still an upgrade for me ^^
i am sure its definitely a SOFTWARE problem, official lenovo forms also has a thread about this problem..
so lenovo would patch up in their next update
It is software, but it won't be patched. There needs to be a certain amount of space at edge of screen (dead zone) to allow swipe up of navigation buttons but also avoid unintentional swipe ups. They could tweak the size of the dead zone I guess, but I don't see it happening. Alternatively they give an option to totally deactivate on-screen navigation buttons and accept some apps may have issues.... I guess it is a trade off. As I say, I cannot see Lenovo changing it.

The last option would work for me I guess, although you do need the navigation buttons sometimes for older apps that still use the menu button.

Ah, found it. They say it's required for the "swipe up" gesture... Seems strange to me, but let's wait for another reponse from Lenovo...
I have the nav bar enabled all the time so I didn't noticed this issue.
But why there is no option to turn the swipe function off, because we can use the full functionallity with the home button?..

Have u checked through Lenovo app in the phone? Run diagnostic through the app, if any point in the screen doesn't register the touch, you should be able to claim warranty with Lenovo. I had the same problem, and Lenovo service centre gave me a new unit....

That is not the problem. And if you try the touch screen test in the Lenovo app you see the the bottom area of the screen is white and it cannot be tested. What he is talking about is not a hardware error, it's just a poor implementation in software.
---------- Post added at 01:33 PM ---------- Previous post was at 01:23 PM ----------
Is there anyone in here that have root that have tried Immersive mode? There are apps in Play store that lets you activate this. Does this help the bottom of the screen to register touch?
Is any custom rom resolve this problem? Because I will unlock my bootloader and root my phone to increase the headset volume.

I understand that there's potential issue with the software as many has reported as well... However it's good to confirm that it is not a hardware issue... In marshmallow, you should be able to test it, it won't be whitish... I tested before when I'm claiming warranty for my previous unit... Same issue, space bar does not respond...
