Nexus 4 touch screen defect (dead zone, phantom touch)
I have the same problem, I have a permanent ~1cm tall dead zone spanning the width of my Nexus 4, right about the location of the SIM card tray.
On occasion it is not a dead zone, but rather a "very haunted zone" where there are MANY phantom clicks/drags on different areas of the dead zone in VERY QUICK SUCCESSION. When this happens I have found that constantly resetting the phone (maybe 5-6 times) until it returns to normal (see: dead zone) is the only way to fix it.
That whole situation can take up to an hour to sort out, especially since during the orgy of phantom clicks/drags on the dead zone, the touchscreen is essentially a write off and turning it off is next to impossible, meaning that my phone is bricked for a portion of the day. This happens arbitrarily about once every 5 days.
I purchased my phone from Australia one month ago. Was not aware of any problem until I had returned to where I am currently living in China. I'm absolutely gutted that my first android experience has soured, especially after shirking apple because of (living through years of) their own hardware/software issues.
Why can't I just have a quality, working piece of tech?
So far the warranty options available:
1) Store I bought it from says: Send it to LG Australia (1 non-international warranty)
2) Google says: No google store purchase number, no return
3) LG China? - Can't find any information about LG warranty claims in China.
If I send it back to Australia for repair I will be waiting without phone for weeks, AND I'll get taxed at least $100 by greedy China customs when the phone comes back in. (not to mention the postage there and back)
The problem has become worse and worse as have used the phone. Can any of ye android bros possibly offer any sort of advice or even better, a fix, for solving this problem?

I have this right now. It's about a third of an inch located near the middle of the screen. It spans the entire width of the screen.
I sure hope it's just a software and not a hardware issue. I bought this in the US and I am now halfway around the world.

I had the same problem. For me it was right where the middle row of keys on the keyboard are or where the ring is on the lock screen.
5mm thick bar across the screen. I sent it back to be fixed and it's been fine ever since touch wood.
They replaced the entire screen on mine. This is definitely a hardware issue. I did a factory reset before I sent it back and the problem was still there.
Digitiser is too close to surface I think causing problems.

Guys i have the same problem since this morning.
I tried everything change roms 4.3 / 4,4 and finally returned to stock.
Nothing worked although i had never the same problem before.
So i tried my last chance. Changed radio image with the help of a Toolkit of our forum ( thanks N-Cry Toolkit )
It seems to be fixed for now , i just rebooted.
Hope it will be ok and you could fix yours too

Well it worked. I cant understand the reason yet but it keeps showing after some time. I m trying changing roms / baseband / bootloader and return to stock trying to identify when it doesnt work and why. It's really annoying and i m tired of it.

Had the same touch screen issue for months; had a dead spot in the middle of the screen that would interfere with browsing and games.
Updated OTA to stock KitKat just last week and the problem went away. Hope you guys get lucky as well. :cyclops:

Ok... i created an account here because ive had this same problem for the past month at least, but I think i found a fix. It may take a few people to try it as well to see if its definitive.
I have the same 1cm high deadzone spanning the width of my device just lower than halfway from the top.
My troubleshooting led me to this: If its hardware, its only because the software is telling it something it shouldnt be. I'm sure nothing is broken (i.e., from being dropped, etc.) Something is wrong, for sure, but not broken per se.
I took screen shots of temperature and voltage (using CPU-Z app) trying to figure it out. I paid attention to when it happened and when it did not. I boiled it down to two possibilities: temperature and/or voltage (i can explain how i came to this conclusion if you want... would take a bit more explanation).
I charge my phone with the charger plugged into the wall typically. I live in asia so the voltage is a lot higher (but within the appropriate range of the phone). Yet, lately when i go to sleep, I plug my phone into my laptop to charge, rather than the wall... when i wake up the problem isnt there. About 2 hours later or so the problem comes back.
I tried this for a week (charging my phone with my laptop) and the problem is dissipating. As quickly as it escalated (getting gradually worse) it is now getting gradually better.
Try it and see if it works for you. At night when your phone is nearly dead, charge your phone with your USB port attached to your laptop. Try this for a few days. Maybe it will help. Im still troubleshooting specifics to see if it is definitive.
UPDATE: today, the day of writing this, i haven't had the problem at all and it's been nearly 7 hours and the 3rd consecutive night of charging with USB on my laptop.
Nexus 4 - 4.4.2

My dead zone appeared post-Lollipop update
I created an account for the purpose of also reporting this "dead zone" issue.
I elected, on the Tuesday before Thanksgiving, to opt into the OTA Lollipop update. During the process of updating, I noticed my battery drained all the way to 0, while I thought nothing of it.
When the update was complete, I started to notice a dead zone in the middle of my screen when in portrait mode.
Actually, my dead zone spans an inch of my screen.
I have performed several hard resets, soft resets, learned about the ADK & adb, and downgraded all the way to 4.2.
I took the phone, this morning, to a cell repair shop and the technician said that it's not a hardware issue (although I'm not sure he's right).
So, that's my story. If I find a solution, I'll post it.

these dead spots IMO , are because of bad battery or bad charging ...
have any of you facing these issues have used any wall charger other than the default nexus 4 LG charger ?? maybe ur battery was not charged the way its suppose to be .. or maybe ur battery is getting bad.. can sm1 with the problem replace the battery and see if the problem get solved ???and u can try charging it from the original lg charger for 12hrs straight .. it may(temporary) fix the problem /...

i could try the battery replacement on my nexus, when i get the time, ill get back to you if it works....

ok got the dreaded dead spot where the sim card is, i can't unlock my phone. i dont have usb debug enabled, i can push/pull files in recovery but not much more.
ive tried to change the dpi to move the pattern away from the dead zone by editing build.prop manually and pushing it to the phone but cm13 doesn't seem to take the change to build.prop so the dpi is stuck at 320.
now, im trying to set up usb otg and unlock my phone using a wired mouse and y-cable. but quanta doesn't have otg for marshmallow enabled out of the box and i dont have root access to enable it in an app.
is there a file that i can edit and push to the phone to enable otg_hack?

[FIX] Crazy colors (Yellow/Blue) on LCD

Hi all!
I've seen some guys here with my same problem: the HTC HD2 started to show wrong colors, yellowish display with blue stripes.
Mine started to have this problem when I've dropped it: first it was a temporary problem, pressing on the display would fix it for some hours, but then it became like PERMANENT... and my HD2 isn't over warranty anymore.
So, I've started to search and I've found many ppl with this problem.. I was about to buy another HTC HD2 but luckily mine was temporairily fixed for another time.. and UNTOUCHABLE!
Prior to the last temporary fix I've opened it to see if it was a wrong connection of the flex cable, but nothing.. it _really is_ a mainboard problem, maybe a broken connection of a point
Anyway, when it was temporairily fixed I thinked: well, it is already ****ed, I can only try my last chance...refluxing... so... this is what I've done:
1. Android booted
2. HTC HD2 on the bed, rolled in my duvet
3. Activated a native stability test using my CPU at 100%
4. Waited for 20 mins, my HD2 reached 54°C
5. Another minute at 54°C...
6. Okay, connections should have been refluxed..
7. Stop the benchmark, shutdown the device
8. After some hours I've taken it, and the display was okay.
I've made this 2 days ago and my display seems to be permanently fixed.
NOTE: This procedure is really risky: you've got a lithium battery in your device that MAY explode! Don't be a fool like me and don't make this thing on your bed!
Hope this helps someone
Does it still fix the issue after 10 days? If it does, I'm gonna try to do the same tomorrow.
Other people who have already tried this?
Greetz, and thanks for sharing the info
I have android installed now, but I don't know which application to use to run a cpu stress test. Which one did you use?
Thanks in advance.

Help with Unresponsive/Somtimes Crazy Touchscreen - Might need to unroot....

Hi everyone! Unfortunately, my run with my T-Mobile G2 appears to be nearing it's end.. I've had this phone since November of last year, so fortunately for me, I'm still within the 1-yr warranty. I couldn't find a legit answer on the forum so far so hopefully someone will have the information I need to know now.
Lately, my phone has been getting crazy. Sometimes it would start pressing random things by itself. Apps would start by itself, things would type by itself, etc, etc. Then, at times certain areas of my screen wouldn't work at all, most noticeably the "y," "b," and "h" on my keyboards. And this doesn't matter whether I'm using the stock Gingerbread keyboard or Swype.
To answer any questions, yes I am rooted and I have been running CM 7.0.2. I tried to flash 7.0.3 to see if that would correct my issue but it didn't. I also tried to reset the phone via Privacy within the Android UI and via Recovery, both with no avail.
My question to y'all is how can I fix this if at all? If this problem is not fixable, can someone provide me with the MOST SIMPLE guide as to how to unroot and restore my original T-Mobile stock ROM if necessary for me to send it to claim warranty.. Finally, if I resorted to claiming warranty, does anyone know if T-Mobile will be sending me a refurb G2 or a new one or a completely different one?? Thanks ... This is EXTREMELY UNFORTUNATE.
it happens to me plenty. keep the scroll pad on the side from changing angles in direct light or it goes nuts. if theres any water on the screen at all touch commands work funny. its errors in the optical touchpad and cpacitive screen technology, not the;phone itself.
edit: im stock if youre wondering
It happens even in the dark though. I think its problem with the screen.
Any word on this? the same thing is happening to my phone.
Hui,
I was also having this problem for some time and was reallythinking of replacing the phone until I finally got rid of this last week. To start with I think this is a software issue but I'm still not sure what sw is causing this. n order to fix it I had to install the rom again from scratch and did not restore anything from google. Because independent from whatever ROM I installed the issue appeared soon after I set up the phone. So if you wnt to give it try, do a clean ROM install or factory reset to your phone and then while setting up your device uncheck the option to backup and restore settings to your google account. I know that setting up everything manually does not sound great but it's better than the crazy touch screen.
Digitizer issues
Sent from my HTC Vision using XDA App
Digitizer issues, T-Mobile just replaced my original release date G2 because of it.
They will send you a refurbished model and you have to send yours back in within 7 days or they bill you $400 I believe.
Sent from my HTC Vision using XDA App
I had serious digitizer issues last month and thought for sure that my G2 was finished. Come to find out I had gotten some oil on my phone, probably from answering a text or phone call while eating at work. I took it out of its case and completely cleaned it with a cloth dampened with peroxide...not soaked just damp, and now my phone is back to normal. Give that a try and rule that out first before you replace the digitizer or phone. Make sure you clean the inside and outside of the case/skin if you have one too.
I finally figured mine out. I guess the digitizer is really really sensitive to moisture. I usually take my phone into the bathroom with me when I shower in the morning, once I stopped doing that and gave the phone some time to dry out (in a dessicant container, but rice would work just as well) my screen is back to normal. I guess the steam from the shower was enough to bring up some bugs.

Weird HD2 unresponsive screen

Now I've read about a problem of the hd2 having digitizer problems and that only a replacement will fix the unresponsive touchscreen issue. But why is it that when I can get my touchscreen to work that it works flawlessly until it goes to sleep? Then i have to continually wake and swype and sleep over and over until it responds. It just seems very weird that after it wakes that it never seems to have a problem. I'm using the miui rom right now and have set the screen to never go to sleep. So I want to see how long it will go without this problem. Has anyone else seen this happening with their phone as well?
Make sure the kernel, and Rom are up to date.
I have that too on an AOSP Gingerbread rom. The screen is not unresposive per se but calibration seems off some times, strage for a capacitive screen.
ive had the problem with android before and there were a few different fixes ...
one fix was to turn off compatibility mode
another was kernel
ive also had the problem with wp7 ( nothing a few hard resets and patience couldnt cure )
either way good luck
well since my first post, i hadn't let the phone go to sleep once and it worked perfectly fine. so i decided to turn off compatibility mode and let it go to sleep.... and when i woke it and i slid my fingers down it actually worked. so far it's worked every time. why would compatibility mode mess up the touchscreen though?
i have NO earthly idea! just a little tidbit i picked from a dev. i would speculate but would end up looking and sounding foolish. so im going to quit while im ahead and have actually been of help :-D cheers
Where can i disable compatibility mode?
I get the same problem. I've used a ICS rom for a day or so and suddenly the lockscreen was unresponsive. I thought it was ROM problem, so I flashed Cyanogen 7, but the screen didn't respond as well... I flashed everything to stock (removing magldr and hspl) and the problem stayed... After several restarts the screen started to respond and now it works (sort of). The tricky thing is: sometimes when I go out from some app in android, the screen doesn't respond again. Locking and unlocking the screen fixes this, but only temporarily.
Did this ICS rom screw something (...hardware?!) or is it a pure coincidence that a few people encounters the same problem for the first time in such a short period of time...
And one more thing... my warranty expired 5 days ago... please help!!!
I had this same problem with my phone before my warranty expired; before I flashed any android roms on it, and while it still had stock WM6.5. I called HTC customer support and they had me send in the phone for repair. They replaced the digitizer and I haven't had the same problem since. It was wierd because in my mind is seemed like a software problem because it would respond nicely as long as the screen was unlocked and the instant it was locked the response was very crappy, sometimes it took forever to unlock my phone. So it might somehow be a hardware issue

spare parts!
I repair phone myself and i can say that i get A LOT of hd2's with this problem. For the most part it is the hardware because no matter what software you put on the phone it is just a matter of the luck you have to get it working. My hd2 broke 2 times b4 and it was always hardware. Htc must of messed up with the hd2 digitizer

from what ive seen in photos of the leo mobo it looks like the connection for the screen/digitizer (not sure on hardware) is located right behind red end call/power button and from being mashed off,on,off,on,etc loosens/damages connection.
or is the hardware screen issue just a complete shot in the darks chance?
OH ... ive had the software issue (fixed as i mentioned earlier) AND unrepairable (with my limited tools and balls to physically tear into this badboy) hardware issues.
well, it's been a few days and my phone still seems to be fine. it hasn't once locked up on me yet. i don't know why turning compatibility mode would fix this. or maybe the phones connectors were loose and are now miraculously back in at the same time i unchecked compaibility mode. the only bad thing was that this was happening the last couple weeks and i had given up and already ordered a sensation 4g. or well, guess i have 2 phones now
Its seems possible. Every since I replaced my digitizer with a non OEM one its has never failed on me again. And I hope it never does. There dam expensive.

Compatibility Mode
I also have this issue, therefore I just recently flashed my hd2 with Tytung's 4.0 ICS Rom. As expected, this didn't help very much.. What I am now going to try before I send my phone to HTC is to disable compatiblity mode. BUT, I can't seem to find this compatibility mode check anywhere. Could someone please guide me there?
..
Windows 7
I will be flashing my phone with w7 now, to see wether this is an android kernel bug / softare issue or if this relates to hardware. I also see a lot of people saying that after fixing the digitizer it works again, so it might actually be a hardware issue. I will post my feedback when I have tried with w7.

problem with optimus 7 device. would appreciate the help

Hey,
So here`s my problem.
2 days ago my phone just switched off, no warning, no nothing, and won`t switch on ever since.
I already looked around for people that may have the same problem, but every thread talks about the device that won`t go pass the logo screen. It is not my case. My phone doesen`t even show the logo screen, nothing. You can press the power button for as long as you want, it just won`t start. At occasions, it starts up by itself, only for a minute or two and then turns off again.
At first i thought it may be a software problem, so I`ve cold started it and reset it but it didn`t make any difference.
After, I`ve thought... maybe a battery issue, so I`ve talked with a pal that has the same device, switched batteries. Apparently his phone started with my battery just fine, but mine didn`t work with his either.
Does anyone have a clue about what`s happening?.. If yes, please do share. As much as I like having a phone with a mind of it`s own.. it`s just not dependable XD
Thanks
Probably just broken / defective - if under warranty go and ask for repair or replacement (money back probably). If not under warranty sell as broken or throw to the bin - not to worth repair in my opinion.
I spend the same thing to my myself, LG stinks.

Thanks for answering.
Yes, it was a problem with the motherboard.. got it fixed on warranty. Now I barely use the phone, of fear that it will break againXD. Looking forward to selling it while it`s still functional.

I've got mine just back from repair (second time). It use to randomly reboot, now I hope it got repaired ("faulty electronic components have been replaced" - but I don't know what exactly). What I realize is MAC address change. But as they changed firmware from 1.1.8.10 to 1.0.16.10, I wonder if that's why it has new MAC? Does new MAC address means that some component was replaced ? IMEI does not change.

Charging touchscreen issue

Hi,
I had received my Moto X Play on 21st November. Right from the first day i started having an issue. Whenever i put my phone on charge and use it the touchscreen goes wonky. It registers some touches and misses the others and typing is a pain. Swiping and sliding also results in accidental touches and something i dont want to open, opens up.
Now, initially i though it was an issue with the plug point in my room. But i tried it everywhere in my house and office and had the same problem. (Note: I was using the charger provided in the retail box). I even connected it to my Xiaomi power bank and had the same issue. I used a Samsung charger and had the same issue again. The phone is working perfectly otherwise.
Could this be a charger issue or an issue with the phone itself? HELP GUYS!
