[Q] how to disable part of screen - Nexus 4 Q&A, Help & Troubleshooting

Hi there,
first i am sorry if i am creating this thread on wrong place, i am new on the forum.
Problem i have started when i dropped my N4. I have Ringke Fusion case and it did good job - no cracks no broken screen - everything is at perfect shape...
But, my 3 bottom soft keys are going mad right now. It is like somebody (ghost) is constantly pressing all three of them Then, i figured out that not the buttons are problem but that part of the screen. While it looks OK (colors and everything) touch is not working. Sometimes it does but only if you hold your finger long enough. All other time it is like it has mind on its own. So problem is that lower part of the screen. It is making me issues with every single application i use - always like someone is pressing that part of the screen constantly... you can imagine what it feels like... I have tried to hard reset the phone - same story.
Now, i know that replacing the complete screen will probably fix my problems but this is not an option at the moment. No money for that. My question is: is there a way to totally disable just that part of the screen? Totally disable it? Or perhaps you can offer me any other solution?
Thank you in advance!

Does the bottom part work during Wizard Setup but not after appearing of navigation bar?

It seems it is more like a HW problem. If i press button and hold it for sec or two then it can work but not every time. In the meantime it is pressing by itself - look at the video i made just now, cannot paste the link here since i am new but name of the video is: Nexus 4 - ghost buttons on YT
Honestly, i cannot remember if it was working OK or not during wizard setup... is there a way to start wizard again so i can answer your question?

Dead keys

First of all, sorry if this or a fix to this has already been posted.
The keys on of my hermes are dead-just the 6 and top 2 (msg & ie), the centre scrolling thing works. the outer keys;comm mgr, camera, jog dial etc. work.
i had this problem a few months ago and it worked itself out after a month or so i think. i've opened it up to but it looked fine.
it's a little annoying, especially the lack of the endcall button.
Anyone else have/had this problem?
thanks
merry christmas everyone
strange, its fixed itself
sorry i wasted this thread.
my advice to anyone to whom this happens: leave it be.!
ooh..dead again
It could be related to the white-screen issue. This issue is apparently caused by a weird connection to the d-pad itself (which also controls the mail/internet buttons at the top of the phone, as well as the send/end call keys). I'm currently in the process of trying to fix my phone. Anyway, for some more info, check out this thread: http://forum.xda-developers.com/showthread.php?t=321163&highlight=white+screen
If you start seeing a white screen soon, then you definitely know that this is it.

Touch Screen Not working.. plz help.

Hi mates yesterday i bought a used herm...with excellent condition. but when i opened any dialog. the window closed automatically. and the screen light remains always on. and touch is creating problems.
and after some time the touch screen totally stop working. i dont know what happened. al the buttons are working fine. i upgraded my t-mobile herm to its original t-mobile wm6 rom. and again the touch screen is not working. and the screen light always stay on..
so is this hardware or software problem.?
guide me if you have any clue about this..
according to my thinking.. i think some button is pressed continuesly.. but everything is working fine.. only the touch is not working.
broken digitizer for the touch screen, buy a replacement lcd/digitizer together and replace yourself, about $100Aud. Use Mike Channons site to download the service manual. Use the search function and type in "htc service manual hermes".
As for the light, you will have to use your buttons to navigate to settings>system>backlight>battery power and external power. you can select how long the backlight remains on for.
Cheers...
Hi mate thanks for your reply.. Actually the situation is that. the screen is working perfectly. all buttons are also working perfectly. but suddenly the touch feature stopped working.
that time i was just opening some menus and they closed automatically. it looks like that there is some button pressed. and the screen light never stops. it continuously remains on. all buttons are working perfectly and everything. on the touch feature is not working.
i upgraded my device with genuine shipped t-mobile wm6 rom and again it stopped at the starting screen where i have to click the screen and the device brings the window for stylus adjustment.
so i wanna ask that is this also possible that some touch drivers are corrupted or something like this.? or is this a hardware failure.?
Kind Regards
I had same problem, it was hardware. Thats why I said to change the lcd. It is theoretically possible to replace JUST the digitizer, BUT, it is a MAJOR hassle.
As for getting past the alignment stage, look up Remote Screen Alignment. Its a cab file that stores the alignment settings on your pc. You WILL have to have a friend that has the same phone so you can get their settings as you need to copy them to your pc first. You can then copy the settings to your phone so you can use it until you replace that pesky lcd...
Cheers.....
I had a similar problem with my hermes. After a lot of investigating, I found out that this is a heat related issue with the hermes. The unit will heat up an some connection somwhere gets messed up and continually registers ghost taps on the upper right corner of the screen, which causes the continual opening and closing of programs/task manager. This overloads the phone which then causes the screen to eventually become unresponsive due to excessive computing.
With my phone, it must be heat related because it will only occur during or after heavy use or overcharging. Other people have had this exact problem with the conclusion being overheating. The worse part is, there is apparently no way to fix this, replacing the screen doesn't change anything. setting your screen alignment very far left will fix the problem but then everything you tap needs to be compensated for.
Good luck, hate to be the harbinger of bad news, but it's better to know whats wrong and that you can't fix it then not know whats wrong and keep trying to fix it.
same problem here... only my hermes is overheating already after 5 minutes use...
in the morning it works and when i put it in front of the airconditioning the touchscreen also works...
somebody who has an idea where to look for a solution??

Some of the suggestions in the white screen thread/s might help. The problem is that those who have the heat related problem will find it very difficult to trace the actual fault. The heat may be causing miniscule expansions on the boards / components and connectors. The tiniest of cracks or poor connections can therefore break with the expansion.
Another theory is that rather than heat it might be a capacitor that is breaking down either over time or again through heating. Unless you are a skilled electronic engineer that is virtually impossible to check, particularly since schematics are not available.
You might just be lucky if you dismantled and re-assembled - it might just re-set a connector or adjust a board so it does not get affected in future. That would be very much a matter of luck and of course potentially the situation might be made worse!

Hi mates. I am back with some issue.. i moved my device to a repair center and he said that its a software issue. and he fixed my device without changing any rom.. i dont know how..
but again when i open some window like programs. the right scrollbar make a problem... when i move scrollbar it automatically press the top close button..i aligned my screen 3 times but same problem with right side scroll bar.
and after playing with it. the touch totally stopped.
now the thing is.all the buttons are working fine and everything is working fine. even sms and calls. but when i check sms and press my scroller button. it displays the right click menu instead of opening the sms. and the screen light is continuesly on. as something is pressed. so. i think this thing wil help. i am now trying this method to check my pc.
http://inuchanbt.blog54.fc2.com/blog-entry-99.html
check this out as well.
i will send you details soon.
might just have something lodged between the case and screen.. also to get rid of the screen alignment, cable it up and delete welcome from the startup programs and then reset it.. should get you past it so at least you can use it until you repair your screen

Weird Touchscreen behavour - Video Doku.

Hi, I'm a big fan of the HD2 but in the last two weeks, since i own this device, i'm getting confused by some screen imput behavour that i will present you.
I want to figure out if this "screenbugs" i have to fight with every day, are normal or a hardwaredefect. To make you guys an imagine of what i mean, i uploaded some youtube videos for each bug.
1. The first one i call: The painting edge
This bug is only present if i not have installed the less sensitive CAB from this forum.
Explaination:
Many of you have notice that the glass of the screen doesn't fit exactly in the case of the device. The right bottom of the glass protrude a very little. Then i lightly press on this position, the screen notice a press on the right top...as you can see in notes on my youtube video:
Video 1: http://www.youtube.com/watch?v=c49x9vB4bzQ
------------------------------------------------------------------------
Beforce you say...my device doesn't having any of the following bugs, REMEMBER, This bugs are not present every second. Sometimes i can use the device for 30min without having some of this.
------------------------------------------------------------------------
2. The Electrocardiography
This bug, i think could be the reason for the following bugs.
Explaination: Trying to draw a straight line an you think you device will get a heart attack soon.
On the half of my second try you can see how the device suddenly works normal again.
Video: http://www.youtube.com/watch?v=t54m1dSLnV8
3. The shaking Screen
Explaination:
I have notice that some other guys have this bug too. You can see this on every scrollable screen, like opera, IE, zoomed pictures, the manila tab, startmenu...etc. etc.
Best seen on minute 0:54 in my video.
Video: http://www.youtube.com/watch?v=6hIE_wV4djs
4.The non pressed key
Explaination:
You are cofused about keyboard reaction while writing a text message? You type an "a" and getting a "t"? Than you have "the non pressed key" bug how i call it.
you have to watch on some key input where my finger is totally out of range. I don't mean the fault input next to the key i pressed...
Video: http://www.youtube.com/watch?v=_B1GiyMp_O4
----------------------------------------------------------------
There is a fifth bug i didn't get on video yet because it is very rarely.
I had have this bug only 5-6 times since i own this device, but it sucks realy hard.
I call it
5. The self-typing keyboard
Explaination:
Then i'm typing some text sometimes the keyboard begins to typing without having the finger one the touchscreen. it can be have a duration of 5-10 seconds or 20 letters/numbers.
It can also be watched, without keyboardaction. Then the screen scrolls wild in any direction without any finger on screen.
Video: http://www.youtube.com/watch?v=-fdXU8SoPTg from htcracer211
----------------------------------------------------------------
If someone can tell me if i can embed the youtube videos in this forum...
Go get a replacement, the screen is perfect. Although I admit it does not fit correctly but it is great. I only need the earpiece fix
please watch the videos before you comment anything...
...You're too much electrostatically charged...
...Or something of electrostatic is in the range of your device...
But it's like your touch panel is faulty. Get a replacement (warranty rules)
Have brought it back today...but couldn't get a replacement...no devices
tryed all your test and get no errors on screen, electro worked perfecly, keyboard keeps presing same key without leaving the range, and i cant notice any shaking effect.
So probably your screen is faulty , change your device as fast as you can matte
I have brought it already back, but it seems to be that others have all my listed bugs too. take a look at the poll results. On another forum a guy has tested the "painting edge" on 3 devices after he saw my video and all devices have this bug!!!!
Hey Guys,
I have the first 3 bugs on my HD2, too. But with BSB Tweaks 1.31 i solved the first 2 one by activating the option "Screen Sensitivity".
Hi,
If you look in the sticky thread here somewhere in the LEO section about tweaks and registry changes there is a topic on reducing the sensitivity of the screen.
I think what's happening here is the electric current in your fingers is playing havoc with the screen when your fingers are either close to or on the screen.
Let us know if this helps you.
WB
whow, that's a lot of problems for one device.
I have the "non pressed key issue" : (that's annoying as hell, typing a message is a heavy burden now) and the shakey screen. should i bring my handset back or try the tweaks... I didn't expect this from an 600€ handset

When i was made this video my finger was always with the same pressure on the touchscreen. It was not close...and not weak on screen...normal pressure. And you can see at the middle of my second try where i'm drawing lines in notes that the screen suddenly works normal.
I also wrote in my first thread, that this bug is not every second present...but then it's present its also the reason for some other input errors, like the "non pressed key" i think.
Quick question: How much pressure do you apply to the display (what is "normal"?)? Scince your display is reacting weird to pressure on the bottom right corner, any pressure might be linked to erroreous behavior. Do the shaking related errors remain when you don't press at allk?
to the OP: what ROM are you on ? have you tried 1.48 ?
I can recommende you to use screenprotector film and install cab for less sensitive.
But even without this all I had not this problem Looks like your sreen very sensitive for electrocharging and not have normal ground contact. This is way to warranty service.
lmao >.< sorry mate but get a replacement NOW!! I've never got these problems, everything works smooth and properly, sorry about that...
do u have a screen protector? i am wondering if the screen protector does anything bad to it...
You have the exact same problems I had when I first got my device, the main concern was the device having its own mind and making random key presses, even without you touching it or even being near it. I got my unit replaced and the new one works like a charm.
I noticed today that MY PERFECT SCREEN starting acting weird !!!! Its jittering !!! Damnnnn !!!!
I'm totally spooked by your video's!!!
I personally never experienced these bugs so I spend the last half our replicating your bugs.
The only thing I noticed was that Electrocardiography but I think you have your finger too flat on the screen (it has a too large surface area) because when I write on the screen as if my finger where a pencil (straight up instead of flat) the screen is working as it should!
I think you must have a faulty device. Perhaps try to flash it with 1.48 if you haven't done that already.

On iPhone with exactly the same finger it draws almost a precise straight line. This problem comes directly from HD2's screen, not from fingers, weather, humidity and so on.

touch screen issues

Anyone else having their touch screen stop working property until they have to reboot? It's like it gets way off on where I'm actually clicking.
I have experienced that, but only after I had flashed the modaco rom. I basically returned to stock firmware this morning and am having to re-root my phone...
I have had a couple of occasions where it doesnt seem to respond correctly.
For me its like it looses the calibration, seemed to noticed it when the device is tilted horizontally.
reboot sorts it, only happened once or twice though.
If the phone is in your hand, make sure your other fingers aren't curling over the screen around the edges to much.
I noticed this happening, and backed my fingers off around the edge of the screen and it started working fine immediately.
I think the screen is just extra sensitive.
Curious if that helps.

I read somewhere (maybe on this forum even) that non-multi-touch systems have this problem. Have the same issue with my HTC Magic, but after a while you learn of a way to use the device single-handed while not touching the screen.
I dont know if this helps or not but I have no idea what you guys are talking about

The calibration problem (the screen registers a wrong spot than where you touched) comes up if you try to use a non-multi-touch phone single-handedly, so part of your palm (between the thumb and index fingers) touches the edge of the touch screen. Especially if you are trying to reach a top area of the screen while holding the phone with just that hand, likely some part of the palm touches the bottom of the screen.
If you want to try having the problem, you can touch the edge of the screen with a finger and try to click a link with another. It won't register the right spot.
Supposedly the problem should go away as soon as you lift that body part up from the screen.... so I don't know if this helps the OP or not.
same issue
http://forum.xda-developers.com/showthread.php?t=615711
does not look like its happening all the time. Ran few tests and still can't duplicate the problem in order to find the cause. so far this happened about 3-4 times on my phone.
i hope this gets resolved soon and that its not the touchscreen issue.

I've had this exact thing happen to me a few times. I notice the tip of a finger on the edge of the screen, move it, then it works fine right after. Sometimes happens with the base of my thumb hitting the bottom left corner too.
Just make sure you're not accidentally touching any of the touch area and it'll work fine.
same here

I have had this same issue on my G1 as well a N1. This problem only happens from time to time, as happes with stock ROMs and custom ROMs.
For the N1, I was initial pulling the battery; however, I have found that if I hold the power button down (don't let go) and then touch the screen to unlock or power if off.
I have a friend with the Eris who was having the same problem; Verizon released a patch earlier in the week that seems to have solved the problem for him.

You can perform a soft reset on the Nexus One by holding volume down, the trackball, and pressing the Power button on top. A half second later, your phone will reboot.
I am also having these touch screen problems, and I can confirm I am not touching any other part of the screen to have it interfere with the non-touch-screen interface. I been testing with what people has been saying on here with having any other part of the screen being pressed, so I have been testing it out and I can say its a different response then what I'm experiencing.
Here is what is going on with my nexus one:
1) it happens at random times (my device is on my table and I am pressing buttons with one finger)
2) it only affects the bottom-left portion of the screen when it happens, touching everywhere else is fine
3) it thinks I'm pressing an area around the soft keys, an example is if I press 'A' it thinks I press either the '?123' or the 'back' button, same if I press 'd' it thinks I'm pressing the 'menu' button.
I can conclude that since not all nexus one owners has this problem it is a device issue, which what is going on is probably the same as if someone was accidentally pressing a part of the screen, but it could be part of the device is assembled incorrect or deformed. The physical form of my phone is off on the right side, I can feel the gray plastic part next to the black border next to the right of the screen is a little more raised then the left side.
But there is my experience with whats going on to me and my two cents.
Ive had this a little bit on my device as well, but I think it's a software issue since it went away when I pressed the home button.
edit:
Also it has happened exclusively in Dolphin browser
here too
Sporadically, it happens with my N1 as well. When pointing at the middle of the screen (in a list for example), the input registers 2 cm below my fingertip. Rebooting fixes this temporarily but it is annoying.
A SW update could perhaps cure this behaviour?

I just had this happen for the first time, all my presses were registering way below where i was touching, tilting into landscape in an app then back to portrait fixed it for me.
So now it happened to me too. I have the Nexus One for almost two weeks and I never had the unresponsive touchscreen. Of course I noticed that the center of the softbuttons is shifted upwards and that they don't register very well in the middle where they should and I had the problem before that the sms text input box didin't registered in the center so that the keyboard wasn't popping out but that is all only a problem of adjustment. Today in the morning after my phone was on standby over night I put in the charger to charge it and I got an email with pictures. I scrolled through the email and all of a sudden the screen became totally unresponsive. I tried to scroll and the screen registered at a complete different place. All of a sudden the email was gone because the phone registered the delete button even though I never pressed it. I could close the gmail program but I had a hard time to scroll between the home screens and the live wallpaper became unresponsive too. I decided to do a restart but I had a hard time to press the shutting down button because it was unresponsive too. This all happened not after heavily usage of the phone but after maybe 1 minute usage.
I am sure that I didn't touch another part of the screen when this occured because I realized before already that the screen becomes wacky if you touch it at two different places (lack of multitouch, so stupid to disable it). I hope that this is a software issue too. I can live at the moment with the 3G problem because it doesn't stop me from using the phone. The unresponsive touchscreen scares me more because because it becomes completely unusable.
i've noticed this with low battery. Twice its happened to me, the first time was when i first recieved the handset. and secondly was this morning when my phone was off with no battery again.
anybody want to leave their battery to empty out and try test if this is correct?
I've had this happen a few times in the ten days i've had the phone. I always make sure I'm not double dipping on the screen, and its easy to do since it will exhibit this behavior for a few minutes.
In my experience battery level has no effect on it.
A reboot always fixes the issue.
I figure it's software based.

Touchscreen loosing input.

My touchscreen is almost suttering, like i hold my finger down it will undetect it for a millisecond or so every few seconds, this makes it almost impossible to do my pattern (unless really quickly).
Tried multiple roms, all the same.
Can someone install multitouch test and tell me when they hold there fingers down if it resets, every 1-60 seconds? You'll notice a very quick dissapearance of the blue dot / text.
Thanks,
Ryronz
Okay ignore me, im being newb. Appears to be Digitizer, if i press firmly on the bottom half of the screen it sets it off. Will see about replacement.
If you're talking about the unlock screen, did you see my thread which describes similar symptoms to yours? There's a fix there too.

Well I have a pattern lock, its not so much that its unresponsive. Because its perfectly responsive, so it just keeps thinking i've lifted my finger off.
For example, if I want to long hold an app to move it, it'll just open it, because after about 1 second it resets input, so it thinks i've just touched the app as opposed to actually holding on it.
