Galaxy S5 is Randomly Restarting

[DerekDH520]

I have the same issue, but get this: it ONLY happens in one location. In my case, it's the gym I work out at. And it's not always consistent. I was listening to Pandora and it kept shutting off and then turning on. I thought it was getting too warm. So I shut down Pandora and put the phone down. It still kept doing it. This stops when I leave the gym. I think it might be something beyond the phone. Is it possible that a electro magnetic source might be affecting the phones?

mine seems to be very hot when it restarts, but I don't know if the heat is before or during the restart

I have this same issue, however it didn't start until recently. I had Samsung replace my phone because Lollipop killed the battery. Now my battery life is great, but randomly the screen will go black, the phone will vibrate twice, and then it will restart itself.

Ah, I think I've found the issue: two days ago I was back at the gym. My phone turned off and on about 5 times. The guy next to me asked if it was TMobile as he recognized the ring tone. I said yes, and I told him about it turning off and on. He also had an android and it was doing the same to him. He figured it was the facilities wifi (they have two). For the last two days, I disabled my wifi (killing my data plan) and I've had no problems.

I solved this problem by replace a battery... suggest everyone here don't charge the S5 overnight.
SM-G900H from Vietnam.

I bought a new S5 last week and right out of the box it would reset itself every 4-6 hours at first then every hour or more often.
It did not matter what apps were on, it reset itself even at night. Wifi-off, location-off, factory reset, clean cache, no memory card in it, pull battery out, none of this helped.
I rooted , installed wanam xposed, checked the option to prevent reboots. this did not work either
I updated to lollipop, then factory reset, then clear cache, no apps installed, still it did not help at all.

Went to warranty at samsung service and they reinstalled kitkat, but it kept on rebooting itself, with no other error.
Went back to warranty service and after testing they replaced the pcb (basically the whole insides of the phone). now it works well, no more reboots.

I was a bit afraid because after rooting the knox warranty became void ( the infamous 0x1 efuse) an I have read that this means the warranty of the phone is gone but the samsung people never mentioned it and now with a new PCB the knox warranty is all good again (0x0).

Therefore you people should maybe try the service option first, because in my case it was a hardware fault and trying all sorts of workarounds could have voided my warranty due to this horrible knox seal they have in new phones.

Hello everyone

I manually re-flashed handset from my pc it seems to have fix the software issue.

I have been having this issue too. I am on SPRINT so I can confirm it's not just T-Mobile. I got my S5 a few months ago and the problem started immediately. After a week I had the phone replaced and it's been fine, until last week when it did it once. I thought it was a fluke, but then it did it again tonight. As of right now, it's updating to Lillipop and I have a new SDCard for it. We'll see what happens.

I have had my galaxy S5 since April (a couple weeks after it was released)
My phone has worked flawlessly until mid august.. it has been having this bad habit of restarting it self when I am using it... It is kind of frustrating because I do not know how to replicate this problem and I have been trying plenty of solutions that I have read online.

Things I have done > Factory Reset: I did a factory reset and while I was uploading contacts through kies it restarted
I have used another launcher: it still restarted while I was web browsing. ( did not download any apps for a couple days and problem still persisted randomly due to web browsing)
Turned off Google Sync: It seemed to have solved the problem because it did not restart for like 2 days, but while using Pandora it lagged the music and it ended up restarting again.
Cleared the cache/cookies: did nothing and still randomly restarted.
Removed all facebook applications: problem still persist after a while of use.

It has been frustrating because it also restarts during important phone calls as well... it is just so random I cannot take it in to At&t because I have no idea how to show the problem. I am on contract so I really want to figure something out since it has not even been 2 years.


If anyone has any suggestions please let me know, thanks!

If it is not an app or your SD card. I downloaded lollipop to my pc and re-flashed my phone manually with odin. This seems to have fixed the issue. You my want to try that because sometime the auto push from the cell provider gets messed up so it does not installe correctly. Hope this helps.

I'm on O2 and my phone does the same too

It seems like the only carrier that was mentioned was t-mobile. (which I also have) could this be some of the T-Mobile bloatware/customization?

Hi I have had the same issue, after my phone kept shutting down and restarting, i could work it out. Optus gave me a new S5 and the same thing is happening. I noticed when i put it in my pocket and sat down it was happening, so started trying things, and on further investigation, I found that if I press on the middle of the screen, screen the phone restarts, I tried when it was on charge and it wouldnt do it. Seems only when it is on standby it happens.
Cheers,

TG

It is happening to me on Verizon as well. However, now that I think about it, it only started happening after an update to my operating system about 3 months ago...

I am not using any SD Card in my phone. Also I have no problem with any application. I have also flashed the fresh OS with ODIN and still the problem is there, my phone still restarts randomly. I can confirm that flashing with ODIN is just wastage of time it has not fixed the restarting problem at all. I purchased my Galaxy S5 directly from Samsung in UK, and it is not locked to any network provider and standard BTU firmware on it.

Mine will have that issue too, where it goes black, vibrates twice then restarts. I've kept my eye on it, and it'll reset regardless of what's happening. I could be browsing on Chrome, using the Google Play store (today's example), listening to podcasts, or it may just be sitting on the desk. There is no rhyme or reason why it should be restarting like this, as far as I can tell. I had the memory card in another phone and it worked fine. However, I formatted the card before I put it into the Galaxy.

One piece of software I've been suspicious of is Clean Master. Anyone else?

that's funny that you mentioned clean master I have similar issues....bye bye clean master welcome back advanced task killer

I also want to add that I am using lollipop and I am using the most latest firmware. I am also not using anything like clean master. But self restarting is still there.

Does the phone randomly restart when running in Safe Mode?

See #1.4 of S5 Lollipop Update Problems - Dummies Guide for instructions and video on using Safe Mode.

My random reboot frequency is quite low. That is once in a day. I cannot keep on running phone in Safe Mode for whole day.I have not rooted my phone also I have not installed any application out of Play Store. I have not authorized installation of apk files on the phone at all. Also I do not agree on testing phone in Safe Mode, how can an application from Official Play Store can make the phone reboot. Also it seems like a heat problem and these problem only occur when the phone is under real load. I think there is some problem with the SOC / hardware of the phone it seems like a Samsung hardware fault. In the Safe Mode there is very low load on the CPU, RAM and other resources of phone, hence it is not good for testing this fault. I don't think that android is made so rubbish that any application from Play Store can make it force reboot.

What firmware exactly, as per #1.8 of 40 Galaxy S5 models - Dummies Guide, are you currently running on your G900F phone?

 

[wicpp]

My phone's model is SM-G900F
AP: G900FXXU1BOD3
CP: G900FXXU1BOD3
CSC: G900FOXA1BOD3
If it is correct as I noted it sometime ago.

I am also on that firmware which is the latest and highest changelist from Samsung to-date. No restart issues for myself or reported by others on this firmware. Have you, as you have no apps on the phone, tried a Factory Data Reset?

Yes I have tried Factory Data Reset thousands of time. Wiped both Data and Cache from Recovery Mode, but phone is still restarting itself randomly.

As the phone is running a stock Samsung firmware, has never been rooted, has Knox warranty intact and is still under its 2 year manufacturers warranty, you should take it to your nearest Samsung Service Point and explain the situation to them.
