Phone won't boot until battery is pulled/re-installed. Why??

For some reason my phone just started having an issue where once it is turned off, even with battery charge remaining, it will not turn back on until i pull the battery and put it back in.
I figured it may have something to do with the custom ROM so I tried loading the backup of my stock ROM and the problem still persists.
Is anyone else having this issue?

I also have this problem...started the thread here http://forum.xda-developers.com/showthread.php?t=1154433
There are other few people who have stated the same with them too.
I went to the service center yesterday and they told me its the faulty battery and new battery is on its way... BUT they are blatantly lying..because before using the stock battery i had used TWO chichitec and then also the same problem occurred...so i went back to the stock battery thinking maybe these extended batteries are fake...however after 15 days the same thing happened with stock.
I am using stock ROM with S-off...no hanky panky stuff to let them say that i violated anything.
I think its a hardware issue which they are refusing to accept at present. Maybe when the new battery faults then they would check the same.
Sometimes it is very frustrating and embarrassing also.

Thanks for the reply. I knew I couldn't be the only one with this issue. Luckily I turn my phone off once every couple weeks so it really isn't a huge deal to me. But between this and the touch screen acting up I'm really starting to miss my rock solid MT4G.

Just an update. After switching to the Senseless Extreme rom my phone seems to have fixed itself.

Have you tried flashing back to stock and seeing if the issue is resolved still? Maybe it was a corruption issue.
Although if you like Senseless then just stick with that.

I am on stock but still facing this problem...I doubt this is related to software somehow...Otherwise on pressing the power button the phone would have restarted... I sincerely believe this to be a hardware glitch because the power completely shuts down and the current stops flowing from the battery to the hardware.. For me it happens sometimes in 20 days and sometimes (very recently) happened on two consecutive days.
I have also ordered another SIM (of same carrier) just to rule out that possibility also that my SIM card is old (have been using it for 7 years now)

Hm, keep me posted on what you find out. Mine seems to be just fine for now. But I'll see if the problem returns in a few days.
And, Termic - I am loving the senseless rom. I forgot how much I love pure Gingerbread. I'll be sticking with this one for sure.

You are right, it is a hardware problem, I solved it by buying another battery. Everything is perfect now.
P.S. get a higher mAh battery, I got Anker and I'm very happy with

Buddy have tried Chichitec batteries and then also had the same problem...AND not one but TWO Chichtec batteries... both same result...

Nexus 5 Screen Freeze

Was at about 30% battery and the screen froze as in it wouldn't take any touch events. The backlight would react as if the screen wasn't touched. It seems like the touch events just were not registering but the phone worked in the background. Kernel issue maybe? I have been using faux.

Something similar ....
I had a similar experience on the 15th .... took my N5 off the Qi charger and the screen froze when i tried to unlock it.
I hit the power button and was able to unlock and get a few touches in before it froze again.
I was finally able (after much screen off/on cycles) to get down to the developer options and turn on show touches & show cpu usage.
... background processes looked fairly normal when the screen was frozen(touches showed as frozen) ...
I was rooted, stock rom except for xda user Jishnu Sur's N5 camera mod and running a couple tried & true root apps(Stickmount & QuickBoot). Thought some software issue might be jamming up the digitizer i/o causing it to freeze.
Reverted entirely to stock (the Team Win recovery was also experiencing screen freeze - buttons worked fine) including removing TRWP and re-locking the boot loader!!
The screen freezing problem persists ... my conclusion is that it's a hardware issue. :crying:
It's possible you are seeing the same thing, but I haven't seen anything in the forums to indicate it's a widespread problem.
Returning it for a replacement phone ... :fingers-crossed:

Hi,
same problem here from France.
I already returned a Nexus 5, after multiple freeze I tried to format data partition via bootloader, (no rooted phone, following google instructions for stock reset) then the phone crash wile formatting, it never wake up gain.
When I get a new one from google after one or two week same problem appears, and it's append more and more often, since monday my phone crash one time more every night, and all the day today.
A this time I'm still trying to load it sine I came back from work seven hour ago, battery still at 49%.
I think it's and hardware issue too.
I'm very disappointed about Google and I'll never by anymore LG products.
Thanks for reading.

Freezes tend to happen on custom kernels specially if you under-volt it too much. have you done that?

Last week I had the same problem with my new NEXUS 5. IT’S TOTALLY A HARDWARE ISSUE.
LG products are however not so bad in the JAPAN market but still we are expecting a lot from LG technology.

LG services suck.
I am facing the same problem with my Nexus 5. Unrooted, bought 7 months back from India itself, was working fine till around two weeks back,when the lags, screen freeze, blacking out n all appeared. Got it repaired twice at the LG centre. They changed the front display touchpad as well as the charging connector strip. The problem still persists.

S6 Pressing Back Button By It's self (Capacitive key)

I'm not sure how this is possible, but about once or twice a day, the back button on my S6 is pressed on it's own. It has happened when the device has been on the desk, I see the soft keys light up, the device vibrates like they've been touched and the app I was on went back, all while I was not even touching the device.
It's happened mostly when I'm holding the phone but not even close to touching the buttons, and once it happened and pressed the back button about 10 times in a row while I watched it.
The phone is completely undamaged, perfect condition, never touched water, not dirty at all, buttons are 100% clean. Happens while it's charging or on battery.
Has anyone else experienced this?
(My device was repaired by Samsung for a different issue, motherboard replaced, this only started happening after the repair)

i have, started like yours random. then it started happening more and more so when i was at the store waiting for someone i decided to factory reset ( factory reset twice while at the store) but it got worse. couldn't even get passed initial setup the phone just kept spamming back button so i just kept going back. luckily i already ordered a replacement s6 from tmobile since i was having some other issue with the phone. sadly the replacement s6 took over 7 days to get here. shipped through UPS and got to hawaii then for some reason UPS gave it to USPS for delivery. kinda sad that i ordered screen protectors 2 days after i ordered replacement phone and the screen protectors got here 4 days later through USPS. but other than that my NEW ( we all know its refurbished) galaxy s6 so far has no issues. even the no audio on calls is fixed.
also if you are going to order a replacement, be sure to let them know you have a GALAXY S6 and the date it was released. i say this because the 2 tmobile reps i talked to kept asking questions they say it was for them to determine if my galaxy s6 that was what 2 almost 3 months old at the time was still under warranty

My s6 was showing the same issue with the stuck back button.
It started randomly but than it went crazy and stuck. I wasn't even able to use it.
But 1 factory reset fixed it.
But yesterday the random stuck back button started again when the phone was on my desk and it was really hot (weather was hot as well as the phone). I turned it off for a while and apparently the issue stopped.
I'm not sure it's temperature, firmware, whatever related but I really don't want to factory reset it again.

No solution here, but it is happening to me as well

Solved
Hi i had the same problem aswell , i bought samsung s6 in Pakistan, after the update the back button kept pressing ghostly, i went to local samsung repair shop and the assistant reset something from the setting and then it was fine, i even asked him what you did and how you did? but he said it is secret lol very stupid. i could have post the solution if i know it, but i think it is very easy and something to do with setting. i am sure it is not hard/soft reset. i will post this on other forums to help other people.
thanks

having this problem with my phone too, i cant even get it to stay on the settings screen long enough to back up my stuff
edit: well i think i solved it. i tried clearing the cache, didnt work. then i did a hard reset, didnt work. then i went back and cleared the cache and did a hard reset at the same time and it seems to have worked.

+1 same problem. It happens mainly when the phone is on the move. Funny thing it happened 3-4 times while taking the metro (go figure) with the data on. Usually when I turn off the data, it reduces the amount of back press.
Normal reset doesn't solve the problem. It stops after a while, probably when the phone cools down. I can't seem to reproduce it, but I believe it has something to do with the data on.
I don't really want to factory reset so I'm going to write to samsung directly as the phone is brand new.

i am having same issue too.

Did anyone try loading a custom rom and got it fixed ?

I've had that issue with my first one. Took it back ASAP as it was DOA. Got a brand new one 3 days later as they didn't have any in stock. This one doesn't have any problems. Don't worry to mutch about it. Get it exchanged.

It is a hardware defect: When the phone turns up power to the radio to strengthen the connection, it can cause Electronic Noise to leak over the connection into the capacitive buttons (due to poorly insulated shielding tape), causing the phone to think the buttons were pressed. That's why you notice the problem more when roaming -- the device needs to be repaired/replaced.

I have the exact same problem...did anyone contact the manufacturer and got a response on the matter?

I believe it may be an app setting messing with the system settings. My device did it once and wouldnt allow me to use my device. After factory reset it made it worse so i used twrp and wiped everything but my modem and flashed my stock firmware and it stopped and hasnt done it since

Hum that's interesting, thanks for your precious input on this.
I did contact Samsung who asked me to do a factory reset. It didn't change anything.
They redirected me to a Samsung office in Paris, not for repair but for a deeper factory reset... (not sure what they are talking about), but I haven't been there since due to lack of time.
However, I didn't experience the problem since the last update FXXU3QOKN so I'm keeping an eye on it.
Following "faiding's" comment, I'll probably pay them a visit for a replacement.

working "workaround"
workaround:
lower the speaker volume to ~75% in all settings (Media, ringtone, system, notifications, etc...)
Whats going on? why is it working?
some posts ago someone (user called "faiding") mentioned something about EMC leak, or at least he meant to, by mentioning a faulty insulation.
with that in mind i did some testing and found out that the closes radiating component it the speaker... and once you lower its emissions even thought the faulty insulation, the EMC leak is sufficiently low and the 'capacity short' is avoided.
Note: depending on how 'faulty' is your insulation (it varies from one phone to another depending on production line assembly) lower the volume until the issue stops accruing.
not full-proof but working

What worked for me is turn power saving on

possible fix
might be a coincidence, but this worked for me:

Repair tech
It is true that if your in the US and your phone has no damage or any water damage to void your warranty even if you bought it from someone else, u can register the phone at samsung website and then request a repair. It will still have a warranty.
But as I am a Cellphone tech, sometimes I rebuild phones. A s6 came into my shop and i once rebuilt it and worked for a while before doing the phantom touches on task and back keys. So when i pulled the screen up a little off the touch keys, it would stop. I gave up after a while trying to figure it out as i had more things to work on. Back in December i decided to rebuild it again, new screen, new battery, new frame and new back. Turned it into a gold s6 to try and sell it again. Sold it couple days ago, and it came back the next day doing the same thing. So got bored tonight and started to take it back apart. Figured i would try one more thing, replaced the charging port (which is also the soft touch keys) to see if that would resolve it. So far its not wigging out but im letting it sit here and try using it from time to time, with wifi on and a simcard installed. So far its not going crazy, but I will let everyone know if it fixes it or not. As for the "Youtube thing" I tried that, did not resolve. Im guessing its a defective soft touch keys/charging port.
I would not recommend this repair unless your phone is out or voided of warranty.

Hi dslayer83,
I've the same problem with my S6
Could you solved the problem replacing the charging port?
It would be very important to me knowing how to repair the phone because I buyed it abroad. In my country Samsung does not cover warranty.

Up with this thread!
I had an S6 since January.. initially the problem was very random, maybe 1 or 2 times per day, sometimes would go crazy for a while
Then i had some time with no defect at all (a couple of weeks?) without doing nothing
This past week, the phone was feeling like the MENU button (what menu as in this phone there isn't any?) and that was very weird!
Today, it simply went completely crazy, and now is completely unusable... i can't actually swtich it off as the back key is pressed so quickly i don't have the chance of doing nothing!
EDIT: Managed to reboot and wipe cache... now it is useable, but still hits the button from time to time

Update... went unuseable again today.... factory resetting now...
If it works, shall we suspect is something software related?
Update: Not working... it started giving the phantom touches just after the factory reset then suddenly stopped
Worked fine for few hours, then started craza again
Now i have done a wipe and factory reset again, and still unuseable

Random Freezes and reboots after full software reset

Device: SM-G920F
ROM: stock 7.0
Build number: nrd90m.g920fxxu5eqf1
kernel version and its settings: 3.10.61-10958180 [email protected] #1
Not rooted
So my phone has been acting up for good 6 months now. I was getting random reboots and freezes that would last anywhere between happpening just once or going on to continue for a day. Sometimes it gets so bad, that the phone would not work longer than a minute or so and would immediately reboot again. During the freezes the battery gets drained really fast (about 20-30% in 15 mins). If the phone freezes and I reset it (volume down+power) it just reboots and then it could freeze again in a minute.
I went to samsung and they told me it's a software problem, so they reset all the software. In less than a week it happened again, and yesterday it froze while at recovery menu, so it's probably not software. Today I went to Samsung again and they told me that if that's still going on, they have to change the motherboard (which would cost me like $320 and I'm better off getting a new phone anyway). So what would be your advice? Can it still be software related? Or can it be related to a hardware component that can be replaced separately from the board and I should try private repair shops?

Hi, my son has become the same problem on the same phone model.
I put him in a private repair shop, and twice he was dismantled and repaired. If nothing happened on the phone, it worked, but as the problems began to work, they reappeared.
It's some cold connections on the base plate ...
We have ordered a new phone ...

Did you spill water on your phone in the past? may be left it in a foggy or misty area? try to remember. your phone shows symptoms of shorting in logic board. in that case approach a private repair shop that does ultrasonic cleaning. this will mostly fix your phone.

I did not spill anything on my phone, or have been in a foggy area for a while. There might have been some exposure to rain though. Is there any way to confirm water exposure as a culprit (as opposed to a broken motherboard) without disassembling the phone?

I am afraid thats not possible. you have to eventually open up phone to inspect logic board. i strongly recommend approaching to samsung service centre or a private shop(that does ultrasonic cleansing) rather than opening up yourself.

Can't charge or turn on

Hello everyone! I have some problem with my Pixel. I was recording a video in 4k and the phone was charging during the recording. Then I found, that there is just 6% of the battery, made it at least 50%, took the phone off the charging and since then I can't charge, turn it on, start into bootloader, because there is no indications at all, just after pressing power and volume down for about 30 seconds, there is some vibration - I don't know what does it means. What can I do?

If the power is off, you should definitely be able to charge. I see a few possibilities:
The charger is bad
The cable is bad
The charging port on the phone is dirty or corroded
The charging port is broken
Hopefully it's not the last one, but try to eliminate the other possibilities. Be careful when trying to clean the port, so you don't damage or scratch anything. I've read at least one person post that they were able to get some goop out, and then their phone charged normally after that.
Good luck!

Everything with the charging is going well, because I'm using the original cable, with charges my second device right now. The charging port was okey, because it was charging while recording video. The cable was plugged in for a few hours, so the phone should be charged. That's why I still have the question: "What's happened to my Pixel?"

Your motherboard could potentially be gone. Here's my story.
I had a Pixel that I loved and adored. It began to have random reboots. I'd be doing something, and the phone would reboot. It happened sporadically, but was a nuisance because when I'm on call at night, my paging app doesn't start in the background after a restart, so I began missing some nighttime pages. Only happened twice, but it's a bit unacceptable in my line of work.
Eventually the reboots happened more frequently, and then one day it wouldn't turn back on. I tried everything and all i would get with long presses of the power button was a blip of a vibration motor. I talked through Google Support who recommended uBreakIFix. I sent the phone to them (after purchasing a used craigslist replacement) and they said a motherboard replacement was needed. Literally everything in the phone was in perfect condition, I had the phone in a protective case with screen cover since day 1 and there was no water damage. They also couldn't get it to power on. The slight vibration you're mentioning is exactly the issue I ran into and a motherboard replacement is 300+ dollars so I had to call it a loss.

Oh, God... But is there any answer about why this happens?

If you look around, this is not an uncommon issue although it’s also not that widespread. I tried to argue with Google that this was a hardware defect that needs to be covered by extended warranty replacement but they wouldn’t have it. I even argued that the random reboots that I first chatted with support about while my device was in warranty were a symptom of the same issue, but they still wouldn’t replace the phone.

Does this happens on the 2nd and 3rd Pixel versions?

I've had my Pixel 2 for a while now and haven't had any unusual behavior. I love my pixel 2.

I had a similar problem, possibly the same. My Pixel 1 rebooted randomly, but pretty rarely, like once every several months. One morning it rebooted and then a few minutes later died for good. Unlike your phone though, pushing power + down-arrow didn't do anything. At the google-recommended repair store, they tried obvious things like changing the battery and nothing worked. They said that the charging cable drew a negligible amount of current, something like 50-80mA if I remember right.
What is "extended warranty replacement"? When I talked to Google, they said that since my phone was 21 months old, they wouldn't do anything for me.

Yeah your mobo is shot and so is mine.
The extended warranty was a $100 add-on when you bought the phone to insure it for 2 years. This is a scam. Any issues you will find on these devices will have occurred and made themselves known within the first 3 months or 3 years after having the phone. Having bought the warranty also means nothing from a customer service point of view as they will refuse to work with you on anything about the phone if it is more than 15 days past warranty expiration even if you have NEVER made a claim and the problem is an obvious hardware defect that you wouldn't ever assume needed to be fixed until it's already too late and your device is no longer functional
