[HELP] Screen Dead Zone - Nexus 4 Q&A, Help & Troubleshooting

Is there anyway to resize the screen to the working zone only?? My phone's bottom ~1cm has been touch unresponsive for about a month. Been using it with pie upto now, but the dead zone is increasing in size making typing and such very very difficult! I have searched the net for resizing the screen but haven't found anything i've been able to use..

Anyone????

This is most likely a hardware problem on the phone. I had the same problem with mine, only with me, it was the whole left side of the screen from top to bottom. I suggest you contact Google Play if your device is still under warranty. If they want you to send the device back, they have to inspect it and that means you can't have it unlocked or running a custom ROM. If they find the cause, and it isn't your fault, they will give you a new phone in the mail. I did this and the the people I spoke with on the phone were really nice. I got my new phone in about a week.

Yeah it is a hardware problem no doubt. Unfortunately my warranty period is over (the phone is 1.5 years old) and getting it's screen replaced would be quite a hassle as i don't live near the US or anyother place that google operates in. That's why i was looking for an app or mod of some sort to resize the screen to the working region only..

You may want to search some infos about the "wm size" adb command.
That should do the trick for you

ok so i've been able to resize my screen with this app https://play.google.com/store/apps/details?id=com.nomone.resolution_changer&hl=en . lowering the resolution puts two black bars on the top and bottom of the screen. Would have been great if the bars was only at the bottom

Help! Stuck on Align Screen!

Guys, I hope you can help me!
I was using my Imate Jasjar when it was accidentally bumped by another person. the Jasjar fell but it wasn't that high and the floor was carpetted. However, I noticed that whenever i try to tap on the Start button on landscape mode, the calendar application opens up! And when I try to tap V-Bar on the other corner opposite the Start button, the Contacts application opens up. Basically, the soft keys on the bottom screen are the one opening up even if I'm tapping the ones on top! If I tap the bottom soft keys, I thought the Start button or my V-bar would come out but still the Calendar and Contacts applications were the ones that opened. Basically the everything on top cannot be tapped!
On Portrait mode, I can tap the start button but when the V-Bar was tapped it still opens the Contacts application.
I went to Settings then Screen to re-align the screen. I thought it would solve the problem but apparently it didn't! I was trapped in the Align Screen section giving me an endless loop to tap the 5 areas of the screen.
I now did a Hard Reset, and now I'm forever got stucked to the Align Screen part.
What am I supposed to do??? Please help!!!
Hi,
Seen the same problem... Try to guess the error margin of the alignment...
for example instead of tapping in the center of the cross try tapping on left or right... Since your screen isn't aligned you can't press on the center...
Now the problem is hardware, not the MB but the LCD...
After tou figure out the margin error, the Universal will resume and then you ca align the screen via Start->Settings->System, align screen
I'll try to know more about this problem asking my friend.
Best of luck
thanks for your reply!
i also believe that it has something to do with the LCD. there are no cracks whatsoever. problem with the aligning is i have to keep on guessing. and if ever i do align the screen successfully, i'm not sure if re-aligning the screen in Settings would solve the problem.
i would appreciate though if your friend or anybody else can shed light to a solution.
This is a simple problem to solve ;-)
When the allign screen is ON and you have to make the first tap on the crosshair (just before you start clicking away to allign your screen), twist your display from landscape to portrait mode...
Now continue to allign it as usual, and you should finish successfully!
Cheers,
San
unfortunately, after following your instructions, i still went on an endless loop on aligning the screen. i'll try to reflash the rom and see if it would work. i hope it does...
i updated my ROM. still stuck on the alignment screen!
any more ideas?
To be honest, sounds like your screen is broke. Even if you got it to align, I doubt it would be very usable. I think you are looking at repair - if there's no visible sign of damage, you might get away with a warranty repair.
Cheers,
Steve.
Hi
Few months back i've got exactly the same problems (odd LCD behavior, impossible alignment, etc...) with an HP4700. I went to the service center and they had to replace the LCD screen. They did not charge me and take it under warranty. In my case the unit did not drop and i made it clear to them. I would suggest you go back to the service center and forget about the drop in your problem description .
Cheers,
Bruno
I had the same thing happen on a HP 3700, I did not even drop it all i did was install the Quake game for it and after a few days the screen alignment went a bit out. It was usable but definately out by about 1 cm in each direction. The unit had not been dropped. I went into the allign screen utillity and ended up in the infinite loop. The only way to fix was a new screen. But unforunately it was no longer under warranty. The screen consists of 2 separate parts the lcd and the touch screen bit. In my case the lcd had no issues just the touch screen. Very annoying but there you go.
Search your soul and do what you feel comfortable with.
Good luck
Charlie
thanks for all your replies!
i've made several searches yesterday with similar problems (even if they're using different PPC models) and they all ended up sending back their units for repair. there's even one who posted in expansys with the same exact problem!
we'll be sending it back through expansys (we got the unit from them) and hopefully get it back before the end of the month. and yes, i won't tell them that it was dropped, he he :twisted: and they won't find evidence either on the outside because there are no physical damages. what a start of the new year for me <sigh>
right now i'm back using my XDA IIi.
thanks for all your support! this is my first thread/topic in this site and it's so unfortunate that it had to be sort of a negative one. looking forward to be active more here!
Hello there
This might help (I am currently wrking with 200 PDAs so have had this a few times)
THere may be a iece of dust/biscuit crumb etc, under the edge of the casing above the screen, try using a post it note or paper and go around the casing/edge of screen, this should clear the screen of anything that may be causing this problem.
THis worked for me on the majority of non-aligning screens

My story was, one day when I needed to twist the screen, it was a bit stuck so I twisted a bit harder, yes it went back. Then few days later, the mis-alignment started and since then I have been keeping to do re-alignment my screen.
My screen is mis-aligned once every 2 or 3 days or even few minutes then I have to re-align by using WM5's alignment program. It sometimes takes me 2 or 3 times or even one time.
The most anoying thing is it keeps forget after aligned screen.
Now, certainty, I don't think it is a screen problem because after running alignment app, it correctly pointed into the right spot but then it forgot where the right position was.
I have done the upgraded ROM ( even tried Ivan AKU 3.2 ROM ) but problem still persisted.
I just tried clean up the edge of screen, finger cross, hope it fixes my problem.
Bad thing is, I bought my device from UK and I am living in Australia so therefore, my warranty is definately invalid. I don't want to spend 200 AUD for the new screen ( unless I am 100% sure that LCD is faulty ).
Anyone has any idea or even a better suggestion because I don't see many people having this problem.
I suspects that maybe the flex cable got ripped but not totally ripped. Don't know , please help me out on this one
Best regards
Anyone has any idea about my problem ??
One question :
I know that the flex cable has 2 connectors ( one is for LCD display and another is for LCD function ). Now does LCD function relate to the touch screen function ? and if one tiny wire of the function cable got cracked, but not totally cracked, will it affect the touch screen function ?
Other thing, does WM5 store any setting relating to screen alignment setting ? If yes, where is it ?
Thanks
Hi, from another forum, it only help to bypass the alignement loop:
"here you go theses are simple steps to bypass the touchscreen alignment.
Install you activesyn blah blah blah when it finds it go on my computer and go into your PDA device
go to windows startup and delete the Welcome file
after that give your PPC a soft reset and BAM u by passed the screen now get a free desktop program liek pocket controller from the internet it will automatically install on your pda and BAM you can control your pda add music and whatever
but now if you want to click stuff on the road get pen irazu just search on google and send it to your PDA then go to file explorer and double click it and you got a cute little mouse program that you can use like a stylus"
also try this little soft:

Hi godtakeit!
I've had the same problem a few weeks ago (and still having it from time to time) and for me a slight (very careful) bending of the screen makes it work again. It seems to me that there are connector behind or near the display which has some loose contacts.
Did you notice any other problems which came in conjuction with the alignment problem (e.g. speaker not working)?
.ox
Hi oxident
No, I don't have problem with speaker ( it was not working before but it is because of the jack plug problem - it solved ). Yeah, I did notice if I bend the screen carefully, the problem is gone. The funny thing is when I aligned the screen, it worked but if I closed it off and left it over night, it started again when I opened the lid.
You may right about the connector between LCD screen and mainboard. Well, I have no choice but openning the device and check it up.
Also, I read the thread somewhere in this forum and somebody advised this problem maybe relates to magnet around device. My brother aslo advised me that LCD charged and reserved negative electrons. Wierd but I am experiment it at the moment ( taking off battery and leave the device for a few days so that it can release the negative electrons ).
Hope it fixes
please help

Problamatic LCD screen on my Wing looking for help.

OK I have had my T-mobile Wing aka HTC Herald since last April.
Just a few days ago I encountered a problem with my lcd. And I would like your guys feedback if possible before I purchase an lcd replacement.
My problem is when I slide open the wing my screen starts to fade, (almost making it look like a negative from a picture) after that it starts to fade to different colors.
Now the problem persists when the phone is closed, however if I tap the top of my wing and hold it the screen becomes normal, but once I let go it starts to fade again.
I would like to know if any of you experienced this with ur phone and if a replacement lcd screen will fix the problem or am I sol?
If it helps im running my wing on Open Touch v6.0 WM 6.1 Build 20273.1.3.3
Thanks in advance.
LCD problems
Hello,
I too have some weird LCD problems and instead of creating a new thread I thought of posting in this one.
For the past few months, whenever I get a call or resume my phone from standby mode using the power button the entire screen goes white or sometimes it has green or blue colored lines all over them. I have to keep on pressing the power button few times to get proper display. Also whenever I open the qwerty keyboard the display goes blank. Since I am out of warranty Tmobile is not ready to replace the phone and I contacted the HTC customer service and they told that the display unit and some hardware stuff is gone and it needs to be replaced and will cost a minimum of 170$ and will increase if they had to replace some other hardware.
Please note that, my screen is NOT broken and the touch screen too works fine. Recently the display has gone completely blank or too faded even to see whats there in the screen I could barely see the today screen.
I searched and I did not find any similar issues that other folks have faced. Since the LCD and the touch screen is not broken replacing them is not going to fix the issue, correct? I was using open touch and recently I updated the latest official Tmobile release of ROM 6.26.xxx. I also tried the hard resets too.
Any other ideas/suggestions will be of great help for me. Thanks in advance.
I am having some similar problems as well, but my problem is much more severe. My screen is completely black and it just happened this past weekend. When i slide the phone the screen used to flicker but now it black as well. Phone works fine but is useless due to the fact the the screen is out. I remember seeing a program where you can interact with your phone via your pc when something was wrong w/ your screen (cracked, broken, etc.) I have searched the forum but to no avail. The program was very simple and effective. I plan on replacing my phone but would like to retrieve some info off the one I have. I just need that program! Anyone please HELP US!

[Q] Dead zone at the bottom of the touchscreen.

My U8800 has a small dead zone across the bottom of the touchscreen.
I can see the stuff there, no problem. But an area about 32 pixels high (about 3mm) at the bottom of the screen doesn't respond to touch. This makes apps with a bottom toolbar a pain to use (such as Opera, various games, even most launchers...), as I have to touch the very top of the buttons to activate them.
Does anyone else have this problem? Is there a way to fix it? Some parameters in a config file I've not yet seen that I can just tweak or something? I imagine it's just a fault with my device, but it can't hurt to ask...
Update - it responds to tracking (I can drag/scroll/move into, the area) just not tapping.

Same problem I think it's just the old atmel touchscreen so I'm gona take mine back tomorrow and hopefully the warehouse have new stock that have the synaptics touch screen installed even though I bought mine on boxing day can u download elixir 2 from the market go to information scroll down to input devices the more information then hit the arrow twice and tell me if yours say atmel-rmi-touchscreen or if it has synaptics instead please reply asap
if you are on stock rom -> warranty
but if you have custom rom, try reflashing.. i have some problems sometimes with cm7, but just flashing same rom again usually helps, and if didn't, MIUI never lets me down ^^. and if it still doesn't work, flash stock rom and... warranty

Lol yea I'm gona go with the warranty coz I'm already on latest miui but I just wanted to find out if it was a problem with synaptics aswell or it was just atmel
Ah, yes. Mine's an Atmel. While the 'dead' zone is only a couple of millimetres, it can be an inconvenience... I might consider returning mine to the Warehouse too.. Warranty permitting, of course.
Haha yea gona be hoping I get a synaptics

I have the same problem with my screen, a stroke of 4-5mm on the right of the screen doesn't respond. I have a synaptics screen and I'm going to send it back next week.
It could be hardware problems or not ? i have this problem and i'm finding the replacement, but seems it's hard to find a touchscreen with the frame in Vietnam

[Q] Top half of screen is unresponsive. Is it possible to fix?

So I cracked the top corner of my screen and now the top half doesn't respond to touch. I was wondering if it would be possible to fix this without purchasing a new screen. I'm not too sure how digitizers work, but I was guessing since the bottom half works fine, maybe a connection came loose and I can fix it without purchasing any parts. Does anyone have experience with this?

I`am afraid you have to have the screen replaced. Can`t fix this any other way. The digitizer is part of the screen and will be replaced as well. Had that once with a S3. It will cost you about 200-250 euro`s.
Your only option is to get a screen replacement or send it LG to do it for you. I had to replace my screen a couple of months ago. I did it myself. Really easy to do, its just expensive. I paid close to $200 for my screen replacement.

Was about to start a new thread when I found this one. Here is what my first post would have been (seems to be software rather than hardware issue):
When I try to pull down my notification bar, I can't. My phone recognizes my touch, but only as it would be just below the notification bar. When I add a second finger, it works perfectly. The same goes for the bottom of my screen. These "half-dead" zones move with the hardware when I turn the screen, not the UI. A restart made it work for about 5 seconds.
Any ideas? Could be a service/app that starts and blocks something, but haven't installed anything in a while now. Also have been going on this ROM for about 1 week now without any problems.
About my phone:
Nexus 4
4.2.2
ParanoidAndroid 3.60
Attachements
1. Here I have my finger on the very top of the screen, but it only recognizes my x-coordinates properly
2. Dito, but in the bottom
3. One finger in the middle, then trying to pull downwards with other fingers and it recognizes it all, both using two and three fingers in total.

Ghost touchscreen

Hi to everyone.
From 1 week my Mi9T has a ghost touchscreen.
How can i resolve it?
What do you mean by ghost touchscreen?

Screen responds to 'touches' you didn't actually make - like, there is a ghost touching your screen
oh, well i dont know how to fix that sorry. But maybe you touched the edge of the screen accidentally?
i have the same problem for about a week now! did you find any fixes?
me too
Me to. I have tried every possible solution. Eventually whole screen has been replaced on warranty.
No guys i dont find any solution. And now? How we can resolve it?

replacing the display is the only solution
i have the same problem, ghost touches in the upper side, near clock.. specially when phone is hot or i press the top of the phone
Im so angry ??? bc we have this phone not usable!!
It's a hardware failure. Faulty display. If you suffer from "ghost touches" you should back up the data you want to keep, and return your Device to where you have bought it from as it might still fall under warranty (depends op what the cause is, and where you live). This can also get worse over time making the screen partially unusable (which was in my case). contact the seller, or contact customer service from Xiaomi.
I suffered ghost touches at the beginning of December (owned the Device for at least a month). Tried every software options i found around internet that could resolve it, but it was to no avail. I proceeded to unlocking the bootloader, install TWRP, flash a custom rom... For a couple of days i was fine. After those few days the top part of the screen (the part with the status bar) rendered unusable, on custom rom and stock miui. Tested it and it seemed that the area increased and also decreased from now and then, which is strange. After contacting my seller they agreed on sending it back including screenshot and the tests i ran. 1 day after they received my device they contacted me to say that it cannot be fixed (or at least they didn't seem to bother as the phone's pricerange is low) and i am receiving a complete new one (this was in the weekend btw). After that weekend on monday i received the new one and it's running better then ever, even the fingerprint is much faster.
Now just as a warning, I don't say you still have warranty. i live in the Netherlands where unlocking, rooting and all that does not void warranty, and returning a product is very easy to do. But in other parts of the world the companies can screw you over so you'll have to check that.
For those who are asking what is it, juste have a look at mine in dev mode to show the touch : https://www.youtube.com/watch?v=-ZApYI9otJI
This happens to me only when I'm charging the phone, still annoying, , I think it's something to do with the voltage and could be fixed with a software update.
