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.

[Q] Power Issue on Note 3

I was looking and looking for a thread with a similar issue before posting but I had no luck.
My issue is that when I turn off my Note 3 I have a really hard time getting it to boot back up. This happens every time every single time I shut it off. I hold the power button for about a minute with the battery removed to supposedly drain any power as I've read around but that doesn't help. I'm pretty tech savvy and internally the phone looks perfectly fine. The weird thing is that I don't actually have any issues once the phone is up and running to make me think it's a hardware issue. It charges fine, I get data, S pen is fine, no other issues what so ever. I haven't been able to pin point what I'm doing to bring it back but eventually it does end up booting like normal. I try to pull the battery multiple times with no success. I eventually get frustrated and just leave it alone with the battery removed. When I return it boots up just fine.
Anybody else having this issue or heard of it?
Forgot to mention that the phone is stock. I don't have it rooted or a custom rom installed.

Thats weird. Have you tried reseating the SD card. Sometimes it might bethe memory card.

Why turn it off?
Just let it sleep. I can't remember when I ever turned my phone off.

Well my phone's back camera was broken and I was replacing it. Although the issue started occurring well before replacing the camera.

Im having same issue. Replaces camera now phone wont turn on. shows chargering though.

I noticed you also have a thread which states the same thing and I'm not sure if you figured it out yet, but just out of curiosity did you happen to ground yourself while you were working on your Note 3? This goes for any device in general but it's pretty amazing how much damage the static electricity from just your clothes can cause if you're not grounded while working with an exposed main board. If you weren't grounded while working on it though it also doesn't mean that something automatically happened, I'm just saying it's always a possibility at least. One thing I would try if you're having problems powering it up even just in general, is to make sure it's plugged in and charging first and then hold the volume up and power buttons down together at the same time (and keep them held down) until you feel a vibration and then let go. It will take at least 10 - 15 full seconds (and sometimes even longer) to happen, but that should usually get it to power it up whenever it's being stubborn. Another thing I'd definitely check, especially if it was working fine before disassembling the phone, is the alignment of the power button itself (the button you press with your finger) and the actual power button which is located behind it on a data ribbon that connects to the main board. It's actually kind of a flimsy setup so whenever you reinstall the back frame plate you have to make sure the power button data ribbon doesn't shift, or it can cause all kinds of weird problems when trying to power on or off the phone. Anyway good luck and hopefully this helps [emoji106] [emoji106]

I just mentioned this in my response to someone else in this thread, but it actually sounds like yours has the same kind of alignment issue with power button that I was talking about. I'm not sure if you've ever disassembled yours for any reason or not, but even if you haven't it's still totally possible that it could've happened from the factory and especially if you got a refurbished phone for whatever reason. It's a pretty poor design choice in my opinion because it's such a "fragile" setup, and even the slightest misalignment of the power button itself and the button on the data ribbon can cause the exact same problems your having. Anyway if if you haven't messed with it and it's still under warranty I'd say just get a new one, but if you have taken it apart I'd say first thing to check would be the alignment of those buttons (once you take the back off). I've even had to make a tiny little "shim" and wedge it behind the power button on the data ribbon in order to get it to line up right with the button itself a couple of times, so I'd say it's a fairly common problem with these phones. Anyway good luck and hope it helps! [emoji106] [emoji106]

tab gets flickering screen and reboots

I dropped by tablet battery down once and now every so often the screen flickers with vertical lines and this is followed by loss of network and the thing reboots.
I've read this to be a battery problem.
Warranty is still active but I've rooted it and my Knox counter has gone up.
What do you think XDA? Just get a replacement battery?

If you have the ability, since it was dropped, I would open it and make sure connection is tight to battery and screen. Then if it still acts up, get a battery. Several people had battery issues out of the box. All it turned out to be for a few was a loose connection.

i was thinking about that but i'm afraid of voiding warranty. do i even still have warranty? due to the knox?

Well ive opened it up and tightened everything i can see and it seems to work ok for a while, when the charge gets to around 20-30%, the tablet flickers, all mobile connections are lost and 75% of the time, reboots.
So i went ahead and got a new battery. Now this was worse kinda. At random moments, like unlocking the screen, or replying to a message, or maybe just a high cpu load event, the tablet just turns off and is unable to be powered back on without first connecting it to a power supply like a wall charger or a power bank.
The time and date will be reset once its back on and ill have to wait a few minutes before the auto network time setting kicks in before i can use something like whatsapp.
Anyone got any clue what might be causing this problem? Thanks in advance, helpful xdarians.

I'm not by any means an expert or repairman of any kind, just so you know. I'm thinking maybe a loose connection at the terminals on the board the battery connects to or if they use a separate board for the battery to connect to and then to the main board it may be somewhere along in there. Maybe a loose wire going into the tab that connects to the prongs. It sure sounds like something isn't making a good connection. Sounds like a load gets put on it and it and that bad connection can't handle the load.
Might just be you're going to have to send it off...

You may be right. Sounds like a particular connection which does higher load or something. Once i put the tablet in power save mode, the symptoms never reappeared. I dont notice a drastic slowdown in the tablet either. Probably am prolonging the inevitable.

I am facing exactly same issue what you have described and am in same situation, have tripped Knox on my Tab S 8.4.
I can see that you have been able to suppress the behavior by putting it to Power Saving mode. Have you experienced flicker and reboot since then? I am planning to take it to Samsung store not sure if they will honor warranty, did you tried that?

nope, ever since the Power Saving mode solution, it hasnt flickered and rebooted yet. and my warranty was expired by that point so i didnt bring it to the shop. no noticable reduction in performance so far

I have seen this problems on 2 tablets 10.5 and 8.4 the connector where battery is connected on motherboard gets loose which causes reboots and flicker
Solution in my case was resoldering that connector again

i had the same problem, opened up my tablet, just disconnected the battery, cleaned the contacts, pushed it back, made sure its nice and snug, put it all back together and now battery doesn't drain as fast, no more flickers and reboots!

hmm. i'll have to give it a try. you think this may be something to do with condensation?

Sorry for the bump, but I'm having this issue as well on my S 8.4. Custom ROM. The thing with me is that it's not consistent. One day, it will do it a few times; others, no issues whatsoever. I'll try the suggested if it gets progressively worse.

Hey guys,
Unfortunately our home's tablet (Tab s 8.4 Wifi) has the same problem.
It never did weird whatshowever, but when I flashed a custom rom (which went perfectly smooth actually) the screen flashes and the tablet reboots sometimes.
Now it weird that this never happened before and only when I flashed a custom rom it began showing this behaviour.
I am affraid of opening this tablet, and I guess because of the custom rom there is no warranty left anymore (or can this be bypassed by some terminal trick?)
Also I question myself if this is not a software issue, and that it can be fixed with software or so?
Thanks for answering!

My Fix
Hey Guys!
I might have some surprising news to tell about this "issue".
I saw some unboxing video's and saw at what place the battery connector was placed. It was some sort of a 'push to click' system.
So what I did was the following:
I pushed the tablet at the place of the battery connector. I tried this at various places until I heard a *click*.
Now I don't have this issue anymore. Jay!
I hope this will help you too!

I started to have the same issue on a Tab Pro 12.2, presumably after the battery has lost considerable amount of its energy. Normally I remember this tablet to have a dazzling 10+ hours of usage time. Just after some serious usage time of more than 2 years this issue started, along with increasing temperature and finally reboot. From time to time Android gave a warning message about overheating. From time to time charge values drop big values at a time. From 45 to 20 or 80 to 50. Seems arbitrary. This was happening even when I was on stock, then I switched to some Android 6 stock port from some other tablet. Still the same.
I believe the battery needs replacement. (That's obvious after 18 months, I just mean blinking is related to this) Hope I can find a high quality one cause there are several garbage batteries.

[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

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 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:

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...

[Solved] Battery and random reboots

Hi
I have a problem with my G3. When i start it, it shows lg logo then few it reboots again without getting anywhere. But if i put the charger it does work flawlessly. If i take off the charger, few seconds and it reboots. Is it a battery issue? Software or hardware?
Thanks

Yes, its battery problem. I think its time for you to change the battery.

Yes, it is a battery a problem, so i bought a 2nd and a 3rd but the same problem happened with the 2nd in less than a month, the 3rd in 2 weeks.
I wasn't ready to buy a 4th one so i looked around and i found a solution and it's working for me so far without a problem.
the solution isn't mine so all credits goes to Marko Peltonen in Android Central forums.
He explained the problem here
And the solution with pictures here
Some remarks to take in consideration:
the wire should be thin (from a strand);
when you're manipulating the wire be careful not to let it touch the body of the battery (if you peeled the plastic off the battery) when it's connected to the + connector.
the soldering point on top of the control board should be as thin as possible so you can put back the plastic cover
hope you can solve this frustrating problem

It could be a software problem. don't go hardware at 1st. What's your configuration (ROM, kernel, Recovery)?

Everything stock. Flashed MM stock firmware a few days ago.
While it was flashing the lg flash tool crashed on my pc at %70 or so. Phone did a reboot automatically and booted up.
Then the phone started to shut down and restart automatically while it was in sleep mode.
Then i flashed stock mm again. This time it worked. But the phone keeps restarting. It does only restart while the screen is locked. If i double tap or use the power button to unlock the phone nothing happens and the screen keeps black and then the LG logo appears and phone boots up.
Tried different custom kernels, recoverys and rom. Issue is still there. Thats why im thinking its and hardware issue and battery is faulty.
Sorry for bad english

@sakarya making this step properly won't harm you G3 in any way, it'll enhance the power connection because the connection is made by glue and with high temperature it becomes faulty, so yes you can give it a try but before going that far if your not familiar with soldering i recommend you to download and flash a stock firmware from here then go to this page and download the proper firmware you need. since you have this problem when the screen is off, in my case it was random.
You'll find here a guide on how to flash a KBZ properly.
Good luck

Thank you. I will try this.. Bought yesterday a new battery, problem does still exist. Must be a software issue.

Paper trick wont work for everyone. Solder or use a bit of foil and paper for pressure.. I prefer to use a bit of tape as it is a cleaner solution. Batter life seems to fall a bit, just a tad after this mod tho but no reboots fixed 3 out of 3 batteries like this.
The chinese batteries run down quicky.
The anker batteries that also have the reboot issue can be fixed by using the board from the chinese on it fix 1 out of 1 anker this way
