CDMA galaxy nexus - unresponsive to touch

Hello everyone,
Basically went to unlock my phone today and touch screen is not responding, however the hardware buttons work fine. Now i've done some research and found other posts of people with the same problem, however their touchscreen problems seem to be fixed(temporarily, at least) with a battery pull.. mine however is still unresponsive after half a day and multiple battery pulls.
Id rather not have to send in for certified to replace an otherwise perfectly working phone.
Any ideas/suggestions would be greatly appreciated!

are u undervolting?

Nope, sorry forgot to say. Completely stock never unlocked or rooted.
Also i tried getting into recovery to try and do a factory reset but when i select recovery i just get the android on his back with the red triangle..
so instead i just went through the steps and unlocked the bootloader and booted up (in order to give me the factory reset without having to touch the screen)
It unlocked and booted up fine but still no response..
No new recent app installed and never had this happen before.

Mine did this after a few days of owning it, and luckily the store took it back and swapped it out with a perfectly working unit. Is yours within a few weeks of purchase?

Figured this out randomly. Remove battery cover. With phone turned on, press on the area to the to the left of the camera lens until the screen is responsive. My screen becomes unresponsive when the phone is dropped and this fixes it.

hrmm this does not seem to fix either. I also have never dropped my phone, although this seems to be worrisome if the issue is hardware related.
@ tmellen i purchased the phone from amazon and am a few days past my return date :-/
Guess ill just give them a call and hope for the best. Thanks for the ideas everyone.
(update) called amazon and they are sending me a brand new phone.
Knowing this i thought i'd try dailong's method again only this time i was quite a bit more "rough" with pressing down on that area, and it actually worked!
Ill still be taking the new phone once it gets here but for anyone who is having this problem there's a sweet spot on the left edge of the phone towards the top (looking at it with the back cover off) there should be a circle shape. press on that area really hard and it should fix.. weird

Experienced the same on my GSM version a few minutes ago. I had to call my mobile to get it to respond. After that it worked again as normal. I'll see if I get this issue again in the next few days. Hope it's just random

Had the same happen earlier to mine and I was on AOKP. I've had this happen to other phone before, shouldn't be a a cause for alarm unless it happens very frequently. Btw, next time it happens to me I'll give that left side of the camera trick a try.

mine got fixed by removing battery.

Black Screen, phone still works?

Hello XDA members, this time I'm writing to all of you to tell you something that happened to my Optimus G E987 from Claro Argentina, also, to ask you something related to the topic.
I bought this phone about 4-5 months ago, and I have taken really good care of it, without using any film protection or case, it was working perfect and with not a single scratch on it, not even a little hit.
But then, some days ago, I decided to "protect it" a little bit, so I got one of this:
htt-p://i[dot]imgur[dot]com/YtgK1aS[dot]jpg
htt-p://i[dot]imgur.com/la1kI5e[dot]jpg
(Sorry, I'm new to this forum so it won't let me post links)
I used it like.. dunno, 3-4 days. One night, my phone was on 53% battery, to lazy to charge it so I just let it like that. Next day I gave it some use, so it dropped to 33% of battery life, I had to go work so I turned it off. When I finished, I tried to turn it on again, but nothing happened, tried more times and nothing, then I noticed I liiiitle light in the screen, the phone was turned on, but with REALLY low visibility, almost everything black but with a little of sight.
I though it was just a battery problem, so I charged it, but to my surprise, nothing happened, well something did happen, the little bit of sight that I had just went full black with no visibility. I noticed that the touch screen and buttons actually worked, I could "easily" navigate through the phone by just using it as normal, but without seeing (you can do this by just knowing your phone a bit).
And that's the story, basically, after using that case, the phone "casually" stopped working properly, all I got was a functionally phone with a black screen.
I managed to connect it to my pc through wifi and launched Android Screen Cast, to see what was happening on my phone. The glow was at 100% (I tried changing it) and everything seemed normal.
If you don't want to read, here is a TL;DR
>Bought Magnetic* Flip Stand Leather Wallet Case for Optimus G
>Some days after, phone screen stopped working (phone was still normally working, just with a full black screen)
About the Magnetic thing.. is there any possibility that this was the problem? the magnetic thing?
Btw, I sent the phone to tech service because it was still on warranty and they have me a new one, now I'm scared of putting it again in the leather case I bought, I don't want this to happen again.
Something to comment? hope you can give me some advice, thanks in advance!

Also having similar problems as you. Somehow, i am quite sure its the stock rom causing the problem.

Had the very same issue few weeks ago, had to send the phone back to LG ( who replaced the motherboard :/).
I was also on stock rom, had root and unlock bootloader (of course I clean all that **** before sending it back).
For my part, I was unable to go to recovery and download mode was quit impossible to access (may be my finger fault )
BUT! some time if I let the phone off for a moment or spam the power key, the backlight turn back on until I power down the phone, so it's could be a software issue ...
Anyway, an other info, when the backlight was off, if i tried to change backlight level i was getting a error message about overeating or something like that...

[Q] Moto 360 Black Screen -Resolved-

So something quite unfortunate happened to me last night. I factory reset my watch since I installed a new rom on my Moto G, and ever since I did that, the screen is black. Nothing else. The power button isn't doing anything regardless of how long I hold it in or whatnot, and it's just not doing anything, it's a brick. It's not rooted or boot loader unlocked or anything either. When it place it on the charging dock though, the light at the bottom of the dock lights up so I know it's charging at least, but I just really don't know what happened to it. Do you guys think it's toast?
--Edit--
So I spoke to Motorola's live assistance, and if this issue arises for anyone else, hold the power button down for about 2-3 minutes and it should boot into the bootloader, from there you can either attempt a fastboot reboot command or a normal powerup.

I tried your solution. But nothing happened. I think i have the same problem. Mine won't show anything, but when i tried charging, the light on the dock light up. Do you have any other solution? Thanks

I'm experiencing the issue. And my situation is same as @Raging_Ken. Is there any alternative way to manual/force restart? Since we only have 1 physical button. :crying:

Hi @Raging_Ken ! We're at the same boat. Do you any friend that have same situation as ours?

@presario3839
You also got yours from the states? I only know one other people who use the moto 360 and he also got it from the US. I'll check with him tomorrow. Can you check how much will it cost to ask for a replacement in Malaysia? Going there on middle of May, if it's cheaper, i'd rather pay the replacement there. Hehehe

I know it took a few tries for it to do that but at the same rate if you've tried it a few times then that's quite odd, It's also quite a pain how there's just one button to do it with. Hopefully you get it fixed, I really don't have too much else advice sadly D:

I just found out that motorola doesn't have any service center in South East Asia, hence we'rwe're screw. Unless somebody in this forum has an answer that can help us, the best that we can do is put it as an ornament in the bed. Huff. @presario3839

I think there can be three reasons for the black screen.
1. The watch has hung and needs the 2-3 minute bottom press as posted by the OP.
2. You use Watchface or Watchface Pro like myself. It has occasionally crashed on me. After several taps, I eventually have the menu come up and can get to settings/reset. I then have the default Moto face and can reselect Watchface. Hope this bug is fixed soon.
3. Hardware failure. LCD displays have a single backlight and if it fails so does the display.
I hope it's either #1 or 2 that you are running into.

this happens to me whene android wear crashes on the watch. i was able to notice the force close notification before it went to a black screen and did not respond until the battery died. once the battery was dead i placed it back on the charger and eventually it turned on. this has only happened maybe three times since i bought the watch at launch.

I've tried #1 but failed to force restart the watch. #2 seems not applicable to me since I'm using Facer.

[Solved]
Hi,
I faced the same issue suddenly (black screen) since yesterday, i came across your thread today trying to find a solution, and tried every solution posted here (e.g. holding 2~3 min on power bottom) several times, but no success!!
I put the watch at charging dock and the charging LED in the dock is ON.... but the watch is just showing black screen ... until i thought it might be from the USB cable... so i change it with its original USB cable which comes with it in the box (while unaware; i used a cheap USB cable from the market 2 days ago while organising chargers/cables in electricity outlet, without realising that i changed the USB cables), and once i used the original USB cable... it's started to work/charge immediately.

Solved

I hold the power button for 3 minutes, however nothing happened.
Soon after holding i put it back on the charger and it restarted itself and everything was perfect.
hope this works for you.

Yeah. I'm having the same issue. The only thing that allows me to turn the watch back on is to put it on the charger. Been dealing with this for a few months.

after I changed rom I can not associate my bike away bluethoot.
the Debug:
cached bluetooth device for device not found
E / bluetoothDevice (3177) getBluetoothClass () COD is 526 084
E / bluetooth Event Manager Settings (13790) Got bonding been changed fo Mac-addres wareble, but device not added into cache.
someone has this problem?

I have the same thing! Really frustrating.
If I put it on the charger there is nothing. If I put it in a "funny" way the light on the duck is on and I can even see the battery sign shown but it disappeared after a few seconds.
I used different chargers and cables and outlets in my house and other places - same thing.
I even tried a friend's charger (original moto 360 charger) but nothing.
I did try the "holding" (3 min is a bit much, no?) - nothing happens. I do have a blister on my hand from doing that 5 times
Any other ideas?
I bought this watch because I was curious and now i can't be without it. I will buy another one if there is no resolution.

I have the same issue. I put the watch aside for a few days (still haven't exhausted the battery), and then put it on its original charger, a few minutes later, the display come back! Don't know why, and don't know whether it will happen again...

Asus Zenforne 2 automatically clicks on screen randomly on its own

My Asus Zenforne 2 suddenly started behaving unexpectedly.
Even if the screen is locked and closed, phone automatically tries to open but as it is locked, it will show wrong password.
But its keep on trying to open the screen, its like a continuous screen touch happens every time.
After I open using my password, it is accessing the phone automatically like opening application what ever is present and keep on doing something.
So basically phone behaves as some one keeps on clicking the phone continuously.
I thought it might be happening only during charging, but it proved me wrong.
I did restart many times, after every restart for few minutes, it works fine but after sometime, the same story.
I did clear the cache partition, but still same issue.
I did factory reset, it took around 3 hours.
Post that it is working as expected. Dont know what was the issue exactly. I had many apps installed.
But again after few minutes, the same issue appeared. System keeps on clicking randomly throughout the screen.
I am not able to do anything.

i have the same problem to...the screen die...change the screen all will work fine again
mine warranty passed...have to paid hopes yours is still under warranty

Your problem appears consistent with "Ghost touch". It is a well known problem for zenfone 2. You can search about that with the keyword Ghost touch in here or in the google and read about it if you want.
If your phone is under warranty, contact the service center and schedule for the repair. They usually change the digitizer.
If your phone is out of warranty, you can order the digitizer for around US$ 30-50 and change it yourself. There are a couple of instructional video on youtube showing how to replace the digitizer for asus zenfone 2.

Thank you sway8966.
I observed few things
1. When the phone is in charging and little bit heated up, this happens very frequently.
2. After long usage, when the phone is warming up, this issue happens.
3. Sometimes, even it is there lying on the desk, still happens. Wiping up the screen cleanly helps sometimes.
4. Most of the times, the clicks or touches happening on one single row.
5. When the phone is locked as pattern, all the clicks happens on the first row of the pattern lock only.
So not able to conclude, what is the issue exactly. Whether it is screen problem, or due to heating up or due to insulation issue.
I have read multiple posts in many platforms but not able to conclude the root cause of the issue.

My warranty also expired just a month back.
So no idea, how much it will cost and whether it is worth spending the money or go for a new device.

It cost around $40 in indonesia, maybe u should consider to change the screen.
Oh yeah, dont take ur phone to asus service center when ur guarantee is alrd expired, it will cost around $120 to replace the screen :crying:

I also had this issue, but it was due to a cheap glass protector I had got from Aliexpress. I suspected it could be that, since the issue appeared just the day after I put the protector on my phone, about one week ago. This morning it suddenly began happening again and it stopped just after removing the glass protector, and it hasn't happened again yet, so I guess I was right. If any of you also used a cheap protector, that could be the source of the problem. I have now ordered a Nilkin protector, which is supposed to be of superior quality (and is indeed way more expensive) and hope I can use it without any ghost touches.

I had exactly the same problem yesterday but the "ghost touch" problem had happened 3 days after I've put the protector. So I've removed it and the phone works fine again. It was this glass protector : https://www.amazon.fr/gp/product/B01GTE6TUA/ref=oh_aui_detailpage_o02_s01?ie=UTF8&psc=1 so avoid it

OP 3 shuts down after I lock it

Hi there,
I recently changed the screen of my OP 3 because it fell on the floor and did not show anything afterwards (I don't know if this only damaged the screen or also other parts of the phone).
Now, the screen works very well and and the phone does turn on as well (I even type this with my OP3). But I now have two problems:
1) My phone shuts down almost immediately after I lock it (after one or two seconds I can still unlock it but after 5 seconds or so it is dead). It does not shut down while the screen is on, though.
2) It heats quite a lot during using and especially during charging. I know, this seems to be a general issue with older OP phones and happened to me as well, but never to that extent (after charging 30 min it gets overheated which never happened before).
Plus, there are two issues that might or might not be related to these to problems so I add them as well: My volume control buttons did not work before the screen replacement, which is quite odd, because the power button works well. And I think I have destroyed the home button/fingerprint scan while changing the screen.
What do you think, is there any hope of solving these problems without having to buy a new phone?
Best, thank you all!
Clemens

Oneplus 3's sides buttons assembly is really fragile. When i was replacing my screen i replaced it too. With my second display, i broke the replacement button ribbon and installed the original one. So you might broke it.
For screen issue, are you using latest OxygenOS? Because some custom roms have issues with third party displays.

Most likely a hardware issue. To confirm, clean flash OOS latest version (9.0.6 I think) and check. If it is ok, your problem is solved. If not, there are too many variables (screen, volume, home button and any other thing that you disturbed while replacing the screen) to trouble-shoot.
