G2 Powered Itself Off...For Good.

Yesterday I FINALLY received my new G2. Playing around with the device I was very excited at It's functionality and performance. I did get unlucky enough to receive one with loose hinges, but they didn't seem that big of a deal to me.
However, after owning the device for only 8 hours, I tried a little angry birds and setup Galactic Core live wallpaper. I flipped the keyboard open and noticed that the wallpaper disappeared to a black background. Hmmm, fairly odd. Closed the keyboard and still bring it back. Attempted to re-apply the wallpaper which didn't work either. I was getting ready to power cycle the phone when it turned itself off.
Tried pressing the power button and opening the keyboard. Nothing. Tried taking the battery out and then attempting to power the device on. Nothing. Tried plugging in the power cable to both the AC charger and a USB port on my PC. Nothing. Tried swapping the battery with the demo model at work. Nothing. I don't get any sound, vibration or even so much as a charging LED out of the device. I've pressed about every button and the device is non responsive.
So with all of the G2 bugs of this nature I am reading about (People with the same issue except theirs turns back on after a battery pull), is there a trick I'm unaware of or is this thing DOA?

DOA means dead on arrival, yours clearly wasn't dead when you received it , just call tmo and have them exchange you for another one.

Gee, thank you for the sarcastic response.

This is probably a dumb question, but does the battery have any charge left in it? You could try plugging into the charger, waiting a couple of minutes, then trying to turn it on. Past that, I think the only solution would be to have TMO send you a new one.

If you can't even get the charging LED to come up then I would gather you've got a dud phone (hey, it can happen). I assume you'd let it sit there in attempts to charge the phone?
Just for curiosity's sake, have you tried plugging it into a computer?
If all else fails, just go back to T-Mo and exchange it for another one.

Maybe try holding volume down and power for the recovery mode?

nexus 4 won't turn on. stock

having had my phone for about a week so far. been having great experience with it. then BAM! The phone just won't turn on anymore. looks like its completely dead. i mean literally dead. no led light flashing. holding down power button doesnt work either. what should I do now? contact google? is it a defect phone? There was no rooting no flashing. phone is completely stock. and no physical damage at all.
waited 2 month for something like this. I am really helpless and disappointed!

For how long did you hold down the power button?
I had the same issue with the nexus 7 and I fixed it by holding down the power button for 30 seconds or more...

Use an AC power socket and leave it charge for hours. Then try again. Then RMA is its still not coming on.

thanks guys. I managed to turn it back on. but what could have triggered this shutdown? there was no notification whatsoever. if the battery dies there should have been a notification or something right? could there be anything wrong with the phone?

I had a similar issue with mine about two weeks ago and again twice today. 2 weeks ago and today, the phone was on the charger and seemed to go into a deep freeze. My alarms didn't go off as scheduled, and I was only able to turn the phone back on with a very long pressing of the power button. Then just a few minutes ago, I noticed my phone was unresponsive and had to do the same thing.
The phone is not rooted, and the battery was not dead during any of these episodes. In fact, it was on the charger overnight the first two times.
I'll probably call customer support tomorrow.

I just got mine yesterday, got it all setup. awesome. Put it on the charger overnight, with an alarm set....woke up just before my alarm to a phone in deep freeze...long power press (over 30sec) and then tried to turn on regular, and it worked fine.
Is this a defect, or just quirk..

This happens to my phone too but once. My nexus 7 keeps on doing it randomly.. But I had to hold my power button pass a minute..

I haven't seen this... I haven't tried games yet on nexus 4, but on my Evo LTE it got quite warm with games... maybe wait till it's cooled down and try again. What game is it...maybe it's poorly programmed and uninstalling would help most...

yes at first the newely installed games like muffin knight and other umpopular games... but now even my game blood and glory(whos i installed from the first day i had my n4) also causes freeze in my phone .. it happened to me 4x now and i really dont know what to do ... maybe its already a hardqare failure since my b and g caused freeze ..

Volume UP + Power button for less then 5 seconds solved the problem for me.

i9505 does not turn on

Hi to everyone,
I bought my S4 in Germany and I live in France.
My phone, after 10 months started to exhibit strange behaviors:
- Turning off and then turning on by itself
- Turning off and then not turning on, so I had to remove the battery, reinsert it and it then vibrates and turns on for few seconds and then it turns off again
- Sometimes it is able to turn on and it worked
So, I sent it back to the reseller (it was not amazon directly). They told me it presented traces of water and they repaired it on goodwill even if the smartphone should not be repaired because water is not into warranty.
Anyway they sent it back to me, it worked for 1 month, and now I have a phone that doesn't turn on anymore. I told them, they told me it is not their problem and it is not anymore in warranty because I had ONLY one year of warranty (I bought it 'as new' on amazon). Anyway they sent me a new battery and I tried the battery on another S4, it is working, so the battery is not the problem.
I went to an authorized shop to get it repaired but they told me that they wanted crazily expensive money. So, I am a robotics engineer, I decided to repair it by myself and that is why I am here.
I want to ask you what could be the problem. I read until now 2 possible reasons:
1) The power button is faulty. In this case is there any way to connect the contacts the button connects with an hard connection?
2) The USB board is not charging the battery. I tested with a multimeter and the + - voltage on the battery was always around 2.62/2.64 V. I don't know if this is normal but I checked that the part is not expensive.
Thanks a lot for your help.

The USB board isn't expensive but I don't believe the USB board is the problem here. Lithium batteries come partially charged when new, so if the S4 didn't turn on after putting the new battery in it, then the only remaining issue is the power button. Buying a replacement power button should be just as inexpensive as that USB board. Plus, being a robotics engineer you should have basic knowledge of soldering, meaning you could replace the button yourself.

It does sound like a power button issue.
A set of 4 buttons is about 5 dollars on the internet.
I'd recommend opening the phone up and checking the power button with a voltmeter.
If it is the power button, then simply replace it. It doesn't seem hard. Here's a guy with a power button issue. You can see where to check and how to replace it.

Thanks. I will try with the voltmeter. Thanks a lot.

So, I unmounted everything and tested the power button. I am quite sure it is faulty. ( I will be 100 % tomorrow because I could test only with a really bad multimeter) .
Anyway I have a question in the meanwhile. Is it normal that the red charging led doesn't show up when I connect to the power supply ? I think it could be possible that the faulty button induces a problem like that but I would like your opinion about it.
Thanks.

I don't think the power button would affect the LED. A friend had a problem with the power button, but I don't think it cause any problems with the LED. I haven't noticed. But my friend would've noticed if there was any and would've told me, which wasn't the case.

I tested with the GOOD multimeter and it happens what it is showed in the video you posted me in a previous post.
The button has 3 pins:
pin1
pin2
pin3
If I check for continuity between pin2 and pin3 there is, as it should be in a working button.
If I check for continuity between pin1 and pin2 there is, as it should NOT be in a working button.

Having continuity on both checks means the buttons is continuously pressed. So I guess you will have to change it.

Yeah, I know. I already ordered it. It will arrive on Friday.
What I was wondering is if this could give also the problem of the LED. What do you think?

I removed the button. I placed the battery in the phone. Put the charging cable. But nothing is happening. This looks strange to me because without button it should at least appear the battery icon. What could it be ?
Thanks

Maybe your phone bootloader is so old that it came to a situation where samsung's signing for this bootloader version has expired then ABOOT doesn't allow you to boot.
Just a suggestion and nothing else.
But this could be else used by samsung to force you update your phone.

Not if the circuit isn't complete. The button completes the circuit, which would explain the lack of any indicators.

Why should be that ? My phone was working perfectly before and at some point the bootloader is not good anymore. Anyway thanks for the hint

Nexus 6P won't turn on or charge

Hope anybody can help with this. My phone will no longer turn on or charge at all. Not even the indicator light is lighting up when on the charger. Ive tried resetting the phone, holding down the power button and using my computer to see if it recognizes it. Nothing has worked. Does anybody have any suggestions?

You say you've tried holding down the power button; have you tried holding down the power button AND the volume down button? I'd try that first, as the phone is plugged in. If that doesn't do anything, I'd try with a different cable.

There is an earlier thread with many ppl claiming that holding only the power button down for an extended time brought the phone back. They were talking 1-2 minutes and the phone popped back on. Were you not experiencing any issues before it happened out of the blue, or was there a weak battery or phone heat issue first?

Heat issue popped up first. Let it cool. And it was on and still working. I rebooted it and this happened

Sorry to hear that man. Leave it on the stock charger a few hours/overnight and try again? RMA for battery/repair if eligible. If not, try to locate a decent replacement battery.

Talked to a Google rep and got a free replacement thankfully. Wonder what did it though. Only a year old too

There are a lot of hardware issues with this phone, unfortunately. At least you were lucky enough that Google helped you out. If that happened a few months later you might not have been so lucky. Did they replace the phone or the battery?

Same thing happened to me and Google took care of me. So glad I bought through Google originally.

Did you take the phone in for service? What did they do to fix it, if they fixed it... I have a dead phone and need some answers if they are out there. I'm looking through every post that has anything to do with this subject and coming up blank - just like my phone's screen!
Part of my issue is that I had a shut down from out of nowhere on NYE. I was able to bring it back up with the power, volume up, and Bixby combo the next day. Foolishly I assumed it was a fluke and went right back to using my phone just as I had before. I saw an article about disabling the Bixby button, which seemed to be the thing to do... When the phone shut down the next day again, I couldn't bring it back because I no longer have a Bixby button for the combo. It's been down since Jan. 2, and I'm at my wit's end. Can you please update your phone status? I'd appreciate it if you can!

Lol disabling the bixby button in software does not mean you can't trigger download mode. That level of software has no idea what packages you disabled ?

Did you have Substratum themes applied before updating?

Happened with me last night, bunch of updates and then black. I was gonna send to warranty, then someone told me Power + Bixby + Vl down and it worked. How can I find out what did it

When I called Samsung, they were clueless how to get it started again as we walked through all the button combinations they had. It was fully charged when it stopped working, both times. The second time it took me a few days of trying on my own, calling, Samsung and then going into their repair store.
They took it back to work on it after I explained what was going on. He tried several things and came out and told me it may need a replacement but wanted to try one more thing. Hours later, he came back and said he hooked it up to a charger and it had been dead. Once it started charging, it showed the green battery, lightning bolt and blinking circle. It still didn't start normally, but the three button combo worked at around 20%. I'm not sure if he tried before that, but it came back on.
I've discovered that my handset is extremely sensitive to cold temperatures and shuts down. I'm in the Midwest and have been working outside in a tent like structure. I listen to music, books, or podcasts while I'm working. Many times, I will put my phone on a shelf while charging but still listening. The phone shuts off and first I have to wait for it to warm up, then it has to drain the fully charged battery, and then I start charging it again. After the first time on my own, I did the button combo right after it started taking a charge and it worked.
I'm not sure if a replacement phone is the way to go, because if this is common on the S8, I might end up with another dud that would just frustrate me more. I like the phone, but this quirk is annoying.

Last night my phone was charging and accessible fine. This morning I have a green light at the top showing I assume that it's charged but the screen is totaly black. nothing I do brings up any screen. I tried all the button combos I tried plugging it in to the charger and nothing shows any kind of reaction. I tried plugging it into my computer and the computer said it was setting up device QUSB_BULK. Then said it was set up but even after it supposedly complete I could not find the device. What the hell?

S8 Black Screen
Is the green light staying on? This happened to me on one of the many shut down times I experienced. I think I narrowed it down to my phone not liking cold temperatures, but I don't know if that is your phone's issue. It hasn't happened since last winter, so I haven't needed to do any of this for quite some time, but I'm trying to remember all of the steps I took.
I'm gonna suggest getting the battery drained back down to zero. In order to drain the battery when it's black screened, I kept trying all the button combos repeatedly for, it seems like, maybe three or more days... I couldn't tell if it was dead on several of the occasions, but when I had an indication light, it went off after days of doing any and all button combos, just to drain what battery I could.
Once you do that, while keeping it out of any extreme temps, (if there have been any) then plug in the adapter that came with it, using a good quality USB-C cord and charge it again and see if the charging screen comes up. (The Fast Adapter Charger that connects with USB 3.o is the best to use. Samsung wanted me to use the original cord, but I have no idea where that is! I just used a good quality cord.)
If that doesn't do the trick, then it's not the same issue I had, and I wish you luck on finding out and getting it fixed! Don't forget to update the site for others to find out if your tricks work... (You can still try this, but it may be just to rule it out as a possibility.) Try draining it more than you first did, and then plug it in again to see if it takes a change.
If it is taking a charge again after draining and plugging in your power cord, wait until you get back up to at least 20% and then try the three button start (Bixby / Power / Volume Up at the same time) and make sure you hold them for up to 30 seconds or until it kicks on. One time, I think I held it for almost a full minute. But it did take the change, restarted on the three button combo restart, and didn't have any new issues from its down time.
If this works for you, come back and tell us! If not, come back and report what you try and what the results are.
I really hope that helps! Good luck!

Sounds like a system problem, you can try to use the button to force a reboot, if there is no response, you can try to reinstall the system, if this still can not be solved, then you may need to replace the new screen, you can go to Witrigs to see Note 8 screen, they There is an original Note 8 Super AMoled screen for sale. The price is also relatively low.
