I realize this is a worse case scenario, but i used my phone as navigation for the first time today and after maybe 20 minutes of having it on my dash, charging, listeing to bluetooth music while navigating it quit charging and the red notification light started blinking. I had power saver on with the screen at its lowest Automatic Brightness set. I know this is a stress test for it, but lots of other phones I've had didnt have a problem like this. I dont use it as navigation too often, but it cant not charge if i do use it that way.
Anyone elses do this too?

Mine starts to get pretty hot with the basics....browsing..youtube...charging while not using. It's not happening all the time but it gets frustrating. This is my second m8 ( I returned my first for heat issues) so it's happened on both non-rooted m8s.
I went back to the tmobile i bought it from, they hooked it up to a laptop and ran a few tests on it and declared it fine. They said to call corporate tmobile tomorrow (since they took the holiday off today) and tell them whats going on and they can put it in my notes to have the store replace my phone tomorrow.
Anyone else's phone do this? I ask because corporate gave the store the OK to exchange my phone, and if this is a problem with all M8's, theres no point to exchange it.
I am debating on getting a different phone all together. I flashed a few Roms.... Still having the heat issue.

So I was able to trade my phone for a new one at the store,...I'm now past the 14 day trial, so I hope this one is OK.
Are you guys sure it gets that hot? This is the same thing with the M7 and people were saying the same thing. It's thermal conductivity which you guys are feeling. Keep in mind just because your other phones don't feel as hot doesn't mean it's not the same temperature. Here's a video about what happens and how people confuse themselves. The M7 and M8 are different and the M8 should conduct more heat due to it being more metal.

Although yes, it's hot to the touch, I'm talking about the battery getting so hot it quits charging , the Orange led blinks, and the battery starts going backwards even though it's plugged in to the car charger.
That's why I was making sure if it isn't merely it feels hot, and not actually being hot.
Are you using a 1.5 amp or something higher? I notice when I use large amp charger it'll get hotter than usual, but it does charge quicker.
It's a Verizon generic car charger, 1 amp. I'll be using the replacement phone tomorrow afternoon for navigation, I'll report back if it's any better with it.
I Just found a 2.4 amp Rocmetfish charger that gets good write ups at best buy. Wonder if that would help.....2.4a is a lot more than 1a.

The phone has been absolutely rock solid since the day I bought it and I love it. Today however I was using Google Navigation with Bluetooth connected to a headset so I could hear navigation prompts and phone calls. The phone was plugged into a generic Motorola microUSB car charger that I've always used for tons of phones.
The sun was out and hitting the back of the phone so the battery app I had was reporting battery temp at 45 and above.
Anyway even though the phone shows the charging icon and says its charging it doesn't seem to receiving enough juice to charge the phone? The battery kept dropping and I can't tell if this was because the phone was so hot that it stopped charging the battery like my Incredible used to do or if I just need a more powerful car charger.
Then on my second leg of the trip the phone rebooted mid navigation. Started back up and has been working fine.
Anyone have any ideas or seen something similar?

Was listening to Bluetooth music and browsing a site and boom hard freeze and had to pull battery to get it to start. Only thing today is I installed nytimes. I'm going to try uninstalling it since I remember having issues with the app on G2X. Let's hope.

I've had random reboots, but I'm not at all sure what's causing them.
Also, the lockscreen will occasionally become unresponsive, but it seems to fix itself if I leave it for a while.
I guess we just have to hope for a fix in an upcoming patch.

Its common to run hot when using gps. Reboot was probably because battery too hot. Your phone did the right thing. Cool off period.
Sent from my Galaxy Nexus using xda premium
depending on the car charger & phone use, you'll get insufficient juice to keep the battery charging. i'm assuming your moto charger is a 'rapid charger', if not.. then i would suggest trying one out.
this one is pretty decent: Motorola P513 Rapid Car Charger
if that doesn't cut it then the next step would be to use a power inverter(what i use).. only down side is they are a bit bulky & can be noisey to.. but will ensure your phone gets charged up no matter what(gps use, torrent download, etc)
Thanks I ordered the Motorola charger. It was only 5 bucks on Amazon Prime. I hope that works otherwise its inverter time

That's bit a OTT, it got hot but not Nuclear.
I'm finding the GN gets hot just from using it with games/browsing.
The hot spots are on the back at the top, next to camera

I agree, the GN does get warm often. I'm trying to get used to it. My NS never got warm.

i'm having constant reboots. this happened to the first GNex i had. it eventually wouldn't come back on. i even waited a good 12hrs and tested it again and it still wouldn't come back on. returned it and now the people i returned it to are telling me that it's fully functional, and now i have a new one that's acting the same. i guess it's going to die too and then i'll have two lemons on my hand. thanks a lot, Google/Samsung.
I've just had my first two random reboots today. Phone updated with the volume fix ota yesterday morning.
It reboots and then gets stuck at the android updating screen.
Don't know if it is a coincidence that this has started after the bug fix.
This morning I look at my phone to see that it has not only rebooted but the default, first-time welcome message is waiting asking me to log on using my gmail account, etc.
In other words my phone got wiped over night and I don't know why. I did install some phone tracking apps yesterday but removed most of them except for PhoneLocator which I ended up paying for.
So I've spent a few hours restoring things the way they were and right before I got to work the phone did a reboot but fortunately did not do a factory reset as it did before.
I am kind of worried now, I really hope this will not happen again.
Any thoughts? Similar experiences?
I had this "problem" with my Desire. In car, connected to a charger than I know works. Phone not charging.
Basically, as mentioned, the battery will stop charging when it reaches a certain temperature. And the OP mentioned it was a hot day. Plus being on the other side of the glass amplifies the suns heat.
Also a "good" charger is specifically one that has an output of 1A. I and others have found that charger with an output of 850mA and less definitely won't cut it for GPS duties.
The reboots... may be heat. May be something else. Does it only happen when the phone is hot?

just so you know you are not alone - i'm having the same problem with the galaxy nexus i got yesterday. it was constantly rebooting, also showing the "upgrading Android" dialog at startup.
this continued after factory reset and no additional applications installed.
i returned it, waiting for one from the next batch.

Some of us have the GN crash on us while listening to music. There is a thread on it here: http://forum.xda-developers.com/showthread.php?t=1379600
Got my GN Thursday morning. Since then I've had 3 Reboots.
First was actually a full power off while streaming music via Subsonic, plugged into a car charger about 10 hours after getting the phone.
Second was after viewing some flash enabled websites, so not too surprised there (reboot).
Third was just after installing and setting up Google Wallet about 45 minutes ago (reboot).
Wow years of lurking and apparently that was my fist post.
GNex Reboots and Freezes
I am in the process of exchanging my GNex replaced by Samsing. Within 48 hours after getting it in the mail (no rooting or anything, just stock) I was getting random reboots, apps crashing, black screen (unable to wake) requiring battery oull. By the next day it was just continuous soft reboots (starting at the boot animation, not the "Google" screen).
Called Google who transferred me to Samsung who said they need to repair and not replace the device quoting 7-10 days. I called Google back and they said Samsung should have offered to replace the device and the Google rep called Samsung back and got them to replace the device (apparently there's a 14-day window that the device can be replaced).
It was a Friday morning and I was told someone from another Samsung department would contact me within one business day to arrange shipping the replacement and getting my credit card details for the advance replacement. On Monday I still hadn't heard from anyone so I tweeted at @samsungsupport with my ticket number saying i was still waiting and received a call within minutes from a Samsung rep arranging the shipping of the replacement. May be a coincidence, not sure.
At this point, I was quoted Wednesday for a total of 5 days without a phone, unless it takes longer. Unfortunately I only recently switched to a GSM carrier and don't have a spare SIM card phone so the delay is inconvenient. Hoping for a better experience with the replacement device and I wish there could have been a next-day replacement strategy for DOA units.
Good luck everyone.
You need a minimum of 1 amp for the car charger, most chargers only provide 750 mA. Also check the charging method, some of the cheap chargers will not trigger AC mode (Will show as usb charging) and in those cases, you are only getting 500 mA, if this is the case, you might be able to trick things by shorting out the two data pins on the USB cable.
I picked up an iPad car charger, the older ones are 1 amp, the newer ones are 2.1 amps. Toss out the crappy proprietary cable and put in a standard micro usb. Plenty of juice for this thirsty phone.
My wife has a evo 4g and she just went to florida, used the google gps which worked great. One problem she had though was at some point during the trip it stopped charging, battery died, then shuts off and when rebooted started charging again till it was full with a charge. Tell me if you think im roght but i was thinking it was over heating from being on the charger and having the backlight on full brightness. I had my old evo shut down from this before so i was wondering if there is a setting in the navigation to dim the back light when the navigation is not active? to keep it cooler! Im also gonna have her use the 1 amp charger to instead of the 2 amp so it can be less hot... Any ideas would help guys i want to make sure my wife makes it back trouble free with my daughter.
This overheating is likely caused by GPS overworking the processor.
Once the processor overheats, the batter charging cycle stops.
If you put the phone in front of the AC vent it will help cool it.
Screen dimming and making sure other apps aren't running helps a little.
You will see a similar effect in a poor signal area.
I'm wondering if it would help to take the case off. she has a ballistics case. I'm going to have her take off the case and then dim the screen. I found the option to dim the screen during navigation.

Ha,...no,..it was on top of the dash, and here in S. Florida it was pretty hot (90F). But, with that said, I had the windows up, AC on. My previous phones (I'm a phone-a-holic), the S4, G2, Xperia ZL, and Note 3 all worked fine in the same situation. If its a common occurrence for this particular phone in general I'll deal with it. But if its unique to mine I will exchange it. But I'd rather not have to restore another phone if the new one will act the same way.
Maybe I should mention the phone has a clear hard case on it, too.
Hot day, phone in direct sunlight, phone in case, Bluetooth, screen, data, CPU probably running at max, it's all going to contribute. Obviously the phone couldn't keep up with the power requirements. Do you use an official HTC car charger?
I have no problems with charging using Navigation with Co-pilot, it does get warm, but so has any other phone when using Nav apps. I wouldn't use Google navigation as that doesn't have offline maps and will tax the phone even more.
Thanks for responding,...I had it in power saver mode and auto brightness at its lowest setting. I'm not even sure there is an official HTC car charger,...is there? Maybe it's a by product of being a metal case, but my past phones, the G2 the note 3 and Sony xperia zl never had this problem. If this replacement (I was able to swap for a new one at TMo yesterday)phone does it too then I'll deal with, I just didn't know if it's the phone as a whole, or my particular unit.
Okay, so a little background. I was at the gym last night, warming up with jogging on a treadmill. While I was running, I was listening to music through these horrible, horrible headphones. When they are plugged in, sometimes the phone will skip tracks forward or backward for no reason whatsoever, even when I didn't press a button. This was happening last night at the gym, and then all of the sudden, I heard this static crack and my phone turned off. Now my phone won't turn back on. I have tried everything. The phone was charged to about 75%, was running the new unofficial CM12 ROM, and was perfectly fine before the headphones zapped the life out of my phone. I'm almost positive it had nothing to do with the ROM. I have tried almost everything to get it to turn back on, holding the power button for a full minute, the power up and volume down combo for a hard reset, letting the phone sit for a while, even letting it sit on the charger for a while. It won't even take a charge now. It's been a full 12 hours of phone inactivity. Any suggestions?
If it still does not power up, your choices are:
Instant replacement: Verizon store
If you have 6 days with another phone: get online with HTC and get warranteed
I've had better luck dealing with HTC directly. Third party refurbs have a bad reputation
on many posts all over.
Hope it suddenly starts so you can keep trucking...

So you think it's broken? It just seems weird for it to be broken after it was working perfectly fine. Plus, I am trying to buy a subsidized Nexus 6 through Verizon, but it's not in stores yet, so I don't want to get the phone replaced if I'm going to buy a new one. It's a dilemna

Hope it doesn't come to this: if it's dead, HTC owes you a warranty repair/replace. You don't want to be left
with a doorstop. Worst case: you get it fixed, treat new one like your Princess, then sell it on Swappa or EBay
when you get your hands on the Nexus 6.

I had the power button fail in mine. Drove me nuts too. In the end it wasn't all that terrible to replace and cost about $10. what happens if you sorta play with the power button and wiggle it etc...?
You are still getting the charge light too right?
Success! It finally charges now! It wouldn't charge before. For a whole day it wouldn't turn on with any button combo. For a whole day it wouldn't take any charge. Until now. I plugged it into my laptop and voila! The orange light started flashing, and it finally got to the point where the orange light is stable. It is currently now accepting charge from a power outlet, and I assume it will turn on. I'm not gonna push it yet though. But now it charges, so it will work! Thank god.
A valuable lesson was learned throughout this process (and it applies to daily life): never give up and always be persistent! Even if you have a good connection, and suddenly those connections break, you can still rebuild them again. You can still fix these connections (relationships in life) will a little hard work!
My phone just did this again. This time I'm guessing it is a bug with the unofficial CM12 Android 5.0 ROM on high volume. When my headphones are in and I'm playing music, usually at the highest volume, the phone sort of makes this weird static noise and then turns off. Hopefully this time my phone turns on, and hopefully it doesn't take a day and a half to accept a charge. I fixed it before by pluggin it into my laptop, but now that won't work. I guess it's a waiting game. Idk, I just hope it works
You sure its not your headsets causing the problems? I have ran the same ROM vol high using my klipsch earbuds and no issues. Will test again to see

I'm not totally sure. I mean it still could be. I hate these damn headphones. It's fairly annoying though tbh. I have no idea when it will be open to accepting a charge. I just kind of have to see if it'll turn on. I guess I can check again with another pair of headphones when groupon finally sends them. I'm just nervous that if it happens again, I'll have to wait again. Let me know what happens with your phone. Also, I'm open to any suggestions on how to turn my phone back on or charge it again. Thanks.
How many songs played before your phone dies?

It depends. Like the first time it shut off I was listening to one song on full volume. Then after it finally booted up, I was listening to the same song on high volume and it turned off again, but that time it booted back up. This time however, I was listening to a different song and it happened. It's not really a matter of songs played, but rather which song is played. I'm not totally sure though. It's just stupid.
OK I played 4 songs now and did hear a buzzing sound but phone didn't shut off or anything. Remember this ROM is still alpha build status. You could try backing up your phone and flash another ROM and see if you can recreate the issue. That way you know for sure if it was ROM or headphone related
I've heard this buzzing in practically every aosp ROM for the m7. It isn't often but does happen occasionally. It had never caused a reboot or shutdown. My guess is that the headphones are bad. I would stop using those lol.
I guess it was the headphones. Finally got new ones, and everything is fine. I think 5.0 definitely aided it though. My phone turned back on a few nights ago, and I forgot to mention it. Every time I've had to wait almost exactly 24 hours to charge it again. It almost seems like a defense mechanism. But alas, it worked!
Save Note7 from potential exploding!
1. "Inportant" Disable fast charging under battery settings ( there is toggle to turn off)
2. Use OEM wall charger with OEM cable
3. Before charging phone close all active aplications and clear cashe
4. Before charging turn off wifi, bluetoth,nfc etc..
5.DO NOT CHARGE phone ubder pillow or in bad
Hope this tips help you guys and me
Perhaps we should also all be taking acupuncture and subscribing to new age homeopathy therapies? :silly:
If the battery wants to 'go bang' it will, no options will change that fact.
i'll just take my chances ?

It doesn't, otherwise we would have been advised to turn it off by Samsung before the handset is replaced. Or a software update disabling the feature would have been pushed.

Samsung didn't say a word what to do untill replace, but if you read about fast charging, there says " your device will charge quickly but may become hot"
It's got nothing to do with fast charging, it's a fault in the battery that will heat up and catch fire if you're fast charging or not....

I think a lot of people are concluding that heat is the issue and will create the battery problem. I can't see any evidence that heat causes the battery fault to occur.
Well exploding battery will cause heat.... sooo XD... There probably many other component that cause it but anyone willing to force the note7"C4" to explode?
its a battery fault - the battery cells which are affecting the units are drawing too much power from the mains which in turn heats the battery past limit. i've had mine for about 4 days in the UK and three have told me "no recall or safety instructions have been given by company"
and samsung support have said "none of the problems has occured in the UK so you are fine to use and if it gets hot close all apps and place phone in cool place away from direct sunlight"
but samsung did say they were replacing phones. left details and call back will be in 7days
was on hold for 1 hour waiting for them to answer. might be quicker popping into a samsung store and asking about it.
but if people in UK need a piece of mind and wants to ring samsung the phone number to use is 0330 726 1000 *****THIS IS FOR UK RESIDENTS ONLY*****

I got a phone call from O2 earlier offering me to return the phone for a full refund or a partial refund with a different handset.
the option they didn't advise was to hold onto the phone and they will replace them when they get the new stock, they said this has been the most popular option with the majority of people opting for it, but they also said should the phone show any signs of the problem (getting hot when charging or swelling) I can take the phone in at any time for a refund.
chances are 3 just doesn't have all the info yet, but the recall is every phone, Samsung is probably still communicating with suppliers so it is likely a case of the firms are still learning then they will have to work out how to pass on the information to those affected.
I would have to say it's fast charging...or generic adapters. Because I used the original cable with a generic adapter and after charging for some time, the phone was extremely hot. As in ive never felt any phone become that hot. This was maybe in the first few days I got the phone. I saw fast charging was on so I turned that off.
I stopped using that particular adapter as well (which works for all our other Samsung and apple phones and pads) ... And it never became hot again.
I use another non branded adapter with a non Samsung cable in the office to charge and it doesn't get hot there. Doesn't get hot with my non branded car charger as well.
So my guess is it's the fast charging option. Or just that particular adapter. But so far... Fast charging off... With different adapters and cables.. And it's working fine.. And cool
the problem is 100% in the battery, nothing else in the phone is at fault.
basically when they make a battery it is done with layers of material and a catalyst (acid or similar) inside the battery is compartmented, if 2 of these compartments manage to interact with each other due to a fault in the separator you get a runaway reaction, at best you get a bit swelling or a hot battery, worst case it goes critical and fails (goes pop)
if you have a phone with a faulty battery you can play it safe and turn off options such as fast charging, but the fact is if the battery is one of the few faulty batteries in the wild you are only delaying the inevitable.
the only way to protect the phone is to monitor it carefully while it is charging as if the battery is faulty no amount of changing settings will solve the problem as if that was the case they would have released emergency firmwares by now to minimise risk.
but even then when the phone gets warm it isn't always the battery, my battery normally sits around 30-35C (even while charging) but my phone sometimes feels warm but the problem is the CPU running some times at 50-60C making the phone feel warm and not the actual battery.
