[Q] Galaxy Nexus will not power on

Hi all,
I have received my new Samsung Galaxy Nexus just yesterday. When I unboxed it and turned it on it was working just fine and i managed to complete the setup. I was playing with the phone when it suddenly got stuck and just died. Nothing worked to fix the problem. I tried a battery pull, sim pull, powering it with the volume rockers, charging it the whole night (there was no indication it was charging) everything I could find in the forums, nothing worked. Eventually, my girl friend just tried to turn it on and it worked, it just started working. There was no happier man in the whole world than me.
ALAS, the problem returned and now my phone is DEAD.
the thing I noticed that in it's dead state the phone is heating when the battery is inside (not crazy hot but still hot enough to notice)
WHAT ELSE CAN I DO, PLEASE GIVE ME SOME HOPE!

Have you tried calling either your carrier or Samsung? If you just received it, presumably there's someone willing to do a return or warranty work.

unfortunately can't return
unfortunately, i can't return the device. will try contact local samsung rep to fix it but i hoped there is a quicker solution.

So it seems like the phone is still on, maybe just not booting right? Try turning it on while holding both the volume up & volume down keys. So all three buttons held down at once. That will get you into the bootloader, then just navigate with the volume keys to reboot and press the power key. Give that a try and report back.

it did not work either
the phone does not react

Try a different charger and cable.
bow chicka wow wow.

tried that
does not work

can't turn on galaxy nexus
i'm having the same problem....my phone just stunt then turn off it self, and i won't able to turn back on.... did my phone dead or just the battery problem???

Power Button stopped working?

Just wondering if anyone's run into an issue where the physical power button stops working with their GNex? Phone is getting close to a year old for me, but is no longer wake/sleep off of it suddenly and long press won't access the menu either.
Tried a reboot with battery pull in case it was some weird software glitch, but same problem persists.

And apparently Samsung (canada) is no help, said that purchasing it off of Amazon voids the warranty.
Though Amazon is willing to RMA for me -- just need to figure out how to get things sorted since I've changed continents since purchasing.

Yes, my power button stopped working at about the same time frame (a little less than a year). I figured out a routine that worked for me to boot the phone without the power button:
Plug the phone into a charger without the battery
Wait a few seconds after the charging icon would appear (sometimes the icon would flash at the right moment, but sometimes not)
Stick in the battery
Verizon replaced my phone.

i had an unresponsive power button on my htc liberty after a year of use. Which is why one of the first things i did when i got my nexus was to install smart screen on. Now im looking at docks to preserve usb.

Happened to me too on Sprint's galaxy s 2. i just got nexus recently and power button sometimes does get unresponsive but i hope it doesn't get worse.

cell phone keeps vibrating will not turn on

hi. i got a tmobile samsung galaxy s2. I am out of my warranty. i had my phone for about six month thru a warranty exchange.
I was browsing espn.com, then out of no where the phone turned itself off and started to vibrate. I have tried to power it on, and it just vibrates. it turns on a quarter way then begins to vibrate. i left the battery out since the problem started waited the whole night to pass, still just beeps.
I googled how to put phone into discovery mode, but when I do the steps, it also powers the discovery mode quarter way then turns off and starts to vibrate. Is it a sticky power button. The power button presses normally,doesnt resist when i press it.

Sounds to me like a sticky or stuck power button. If you can take it apart...clean around the button that might help. There are a few guides in the Skyrocket forum on how to do it. Search for sticky power button or look at the stickies by Vincom. I have a T989 as well and used some of these methods and it worked. Good luck!

To be honest your probably going to have to the the button replaced I had same issue I tried everything to cleaning it and around it and even prying it away from the connector and nothing worked I had to send it into Samsung and they had to replace the motherboard thankfully it was still under warranty its worth a shot to call em n ask if yours is

I had the same issue, took it apart and tried cleaning to no avail. I called a local cell repair shop and as soon as I said I had an S2 and started to describe the issue, he stopped me and said it was a short in the switch, which had to be replaced, and gave me a quote. Seems to be something of a common issue.

How much was it for the shop to fix this?
I am looking at buying an S2 for $100 that is doing this shut off & vibrate.

I got something similar happening to a S2 I have. I was using it, it just shut down and won’t boot anymore. As soon as I plug it in it'll start vibrating indefinitely, pull the battery and re-insert it, and it'll keep on vibrating indefinitely. Sometimes I see the SAMSUNG logo but that as far as I can get. RECOVERY doesn’t work, ODIN doesn’t work, no button combination works... seems kind of dead to me.
You guys think it’s worth sending it to SAMSUNG and getting a quote to get it repaired?
EDIT: sometimes i can get into download mode for about 3 seconds then it blue screens and reboots. I can get as far as pressing the VOL+ up and then reboots...

So did anyone find a solution or was it a "short in the switch"?

SOLUTION !!! Hey i share your pain... i have an
S2 as well and have been facing the same
problem... my phone is rooted so at first i
thought the problem was due to an unstable
custom rom... anyway the REAL problem is
called a "STICKY POWER KEY". all you need is a
bright light, a can of CRC (the none conductive
type) and a Phillips head screw driver.. you need
to remove the back cover of your phone, remove
your battery and or charger , sim and sd card
then remove the six screws that is holding the
phone together. after that , carefully pry open the
phone and remove the circuit board that has the
power button and the volume Buttons.. this is a
little tricky because in order to get the circuit
board out you will need to detach some
connectors.. now you need to spray some CRC
on the power button using the fine tip straw that
comes with the CRC CAN .. then you just need
to press the power button until you get tired... i
use CRC intermittently while i press, be careful
not to get too much on the circuit board tho..
when you are done , put the phone back together
and let it sit for an hour then replace the battery
and turn on your phone voila ..... feel free to
inbox me if you require further assistance...

Touch Screen stops Functioning randomly?

Hey, I really need some desperate help.
So I have a Canadian Note 2, SGH-I317.
It has no SIM card inside it, and it is just connected to wifi.
I have flashed 2 Custom ROMS before on this phone.
The first one, was a 4.4.2 Homemade t0lte ROM.
It worked fine for about a week, but then I started to have this big problem.
After I plugged in my friends charger at her house, (a Samsung Note tablet charger) then this problem started shortly after I left her house:
When I leave the phone alone, it will go to sleep automatically like every other phone. Then, when I press any button which wakes the phone, the touch screen is unresponsive, and the phone since no input is coming in, goes back to sleep and doesn't turn on again until after a while, where it will boot back on itself and start working until randomly out of chance (chance meaning atleast once every 1 - 4 hours) it will do the same thing again. It's getting really annoying and starting to be destructive, as it stops important conversations and other stuff.
I initially thought it was the homemade ROM.
So, I changed the ROM. Now I'm using a better one, and it's called W03 Slim v9 t0lte, and it's 4.4.2 and works good.
I was not seeing any problems up until a few hours after the install of the new ROM, and the problem which I thought had been removed was still persistent. Now, its even more often than the old homemade ROM. Just before posting this, it has happened twice in the matter of 1 hour, and it's just getting on my final nerve.
I'm not sure if this is a key factor, but after it goes to sleep, I still see the visible white pixels of the 4.4.2 shutoff effect.
My final thoughts are that it might be the battery, but I have no idea how to get a replacement for that, and how much they cost.
Obviously I can't send it in because the warranty was voided when I flashed the custom ROM.
I really need a solution, and ultimately I could wipe everything and go back to the stock ROM, but that, in my scenario would be a last case scenario.
Thanks, Delbert.
NOTE: Just found out that when I turn it on, and the touch screen is unresponsive, the S pen works with the phone, and the back and menu button doesn't work. But, all physical buttons do. The physical home button works, but all the rest except the S pen works. So I can navigate the phone unless it goes into sleep mode, in that case no matter what I press, nothing will make it come up unless it reboots.

your friend's charger could've damaged your phone
i've had a charger that made my touchscreen unresponsive while plugged in... thankfully it didn't do any noticeable permanent damage
all USB chargers are not created equally:

Thank you for your reply, but if the charger did do damage to my phone, how would it and how does the touchscreen still work with the S pen?
Is there any way to fix this, and if not what do I do?
I have an HTC One X I could use as a backup, but I would like to install a 4.4.2 ROM on it, and with what I've found out I have to root it, which requires a recovery, which recovers an unlock or S-OFF, and when trying to do that, the phone won't connect via USB to my computer. I am frustrated but at the same time sad.
Should I just factory reset my whole phone and erase everything?

Possible broken Power IC? Bricked phone? Assistance needed.

Hi everyone, I am looking to troubleshoot my T-Mobile Galaxy S4 which I believe has suffered from a Power IC malfunction. It has all the symptoms that relate to a broken power button, which of I already sent in for repair and that didn't seem to fix the problem. The guy installed a brand new power button and the problem still persists. Continued researching and it might be a broken Power IC chip.
The phone will power on for a second and display the Samsung logo, then shut off and reboot itself and sometimes be in a constant vibration cycle like it's trying to power on. Sometimes it just freezes on the Samsung logo and will not continue past that. Sometimes if I'm lucky, it will boot up like normal but once it gets to the T-Mobile splash screen, the screen will distort and then reboot itself where it will just go through either of the symptoms already mentioned. Weird thing is, I am still able to boot into recovery (takes a couple tries though) and download mode fine without any reboots or anything. I have tried flashing numerous stock firmwares/ROMs via download mode/recovery in hope maybe that'll correct something, but to no avail.
The problem happened shortly after I accidentally dropped my phone getting out of the car. The phone worked fine for a day and then one day while driving, the phone did something crazy and froze up, displayed the power menu, and then shut off by itself. Then after that is when all the problems happened. I took the phone apart and cleaned the power button. Rubbed the contacts with rubbing alcohol and even tried to get inside the power button with some. Took a can of air and sprayed the button until it was dry. I think that was my mistake because I think some alcohol got onto, or into the power IC located near the power button and fried something.
Looking for possible answers as to what could have caused this. The phone will not charge normally unless I boot into recovery/download mode. Plugging the phone in while powered off displays the charging icon with the grey battery and a circle in the middle but doesn't continue past that and reboots itself after a while. Tried a different battery as well and it's all the same symptoms which is why it's something internally.
On a side note, if anybody has experience with replacing the Power IC and would like to offer their service to me, we can arrange a price and continue from there. Please be a reputable member though. Thanks for reading. Hope to resolve this annoying issue.

If you are able to go into recovery mode, have you maybe considered flashing a new ROM?
Do you have some sort of custom recovery? If yes, maybe you could first back up all your stuff to an SD card (in case nothing helps bring the phone back to life).
Since your boot up logo shows up, but the ROM doesn't seem to start, to me it looks like your onboard flash memory might be the problem, not the power IC. The S4 is actually an awesome phone from a repairability standpoint.
Best of Luck! :good:

I will be starting to do power IC replacements in these phone in a couple weeks actually! I have a little cell repair business that i started a few months ago, but I have never done this specific repair. It isn't difficult, and as soon as I have a few successful attempts under my belt I will update you! Although, usually the phone won't boot at all if it has a bad power IC. I would do more research and see what can cause your specific problem. Feel free to message me or just reply on here with questions

Hi Deke. Sorry for not replying sooner. Kind of forgot about this thread after giving up on trying to fix it. But if you are willing to repair it in the future please let me know! I'll give you some business for your repair shop. Congrats on starting one too .
As for the phone not powering on at all if the problem was the power IC, that's what I thought at first too. But after getting a new power button installed and the problem still persisted, the power IC was the next option.
