Galaxy S5 is Randomly Restarting

[tkrusher53]

I got my S5 last August, it worked flawlessly until about November then it started the rebooting item all are talking about. Mine is T-Mobile. I am also seeing this issue with my home WiFi where it is continually dropping and reconnecting to it, this is new in addition to the rebooting issue (at least as far as I know). When it drops I look at the WiFi section on settings, says it is ready to connect when nework quality improves. This happens CONSTANTLY at this point, I am only connected to WiFi from home. There seems to be relationship between the rebooting problem and the wifi as the reboot also happens at work when I am not connected to wifi. I had a day or so stretch about a month back where it reset itself like 8 times over the period, frequency is not that great but multiple times per day. I have a Samsung Galaxy Tab S 10.5in tablet that I got in December, it is also running 4.4.2, am not seeing either issue with it. Both are build KOT49H but obviously one is for the tablet, the other the phone. The kernels were built within 6 days of each other.

I truly believe this is a Samsung issue, not T-Mobile. THe table has been great so far but the bloat ware on my phone is not something I like to see. Experience with my Samsung SMART TV tells me that Samsung does not do software well, their Smart HUB package was crap.

As far as the post about putting some cardboard in the back to keep the batter secure, sound good, someone even mentioned a faulty battery (I have several backup replacement brands) but my latest round of reboots has been happening with the stock Samsung battery and with the phone at rest, on a tabletop. No chance the battery "wiggled" loose (here in Michigan we don't get tremors lol).

I think Samsung has a sleeping giant of a recall on their hands and knows it, don't want to broadcast it out there. In the meantime everyone is looking to deflect the blame.

I forgot to mention battery life. I have gotten, during light use admittably, 68 hours on a charge. A few times the phone went into this mode of sucking the battery dry in less than a day with light use. This is going on at this time. Not even 24 hours on a charge with me hardly using the phone. Not sure how all this is related but wanted to throw that out there.

For what its worth, had the same problem, starting after about a month from new. Randomly restarting, sometimes once a day, sometimes several times, no real pattern. T-Mobile sent me a new one under warranty, and it has been rock solid ever since. Pretty sure I have all the same apps running as before.

I've had my Verizon S5 since March 2014, and it's worked pretty well up until the last 2 days. Last night, the running services began stopping, and the phone randomly would lock up &/or restart on it's own, even hanging up calls in progress. some noteworthy items:
1. It happened on both wireless & OTA signals
2. It happened whether or not the phone was plugged in or not
3. I have 3 separate battery's. Results were the same with each one.
4. Services & apps closing were random. No difference if I cleared individual &/or phone caches.
5.Problem persisted in safe mode.
6. Used developer tools to stop processes...
6. Did a factory reset, and the problem STILL is happening.
OK, what did I miss??? This thing is a big paperweight to me at this point...

This issue is happening more frequently on my T-Mobile S5 also.

Here are some details of my experience:

1. Only happens when connecting to my home wireless network (Belkin router), not work or any others
2. Happens about once every two hours
3. Happens when phone is idle and not under use
4. Phone has been factory reset and cache cleared
5. T-Mobile will not acknowledge a problem as it cannot be duplicated in store

Well, Lollipop is due soon, so I remain cautiously optimistic.

I also would like to do more testing with turning off the VoIP mode... that HD calling is super clear but often drops the calls even under ideal WiFi bandwith. I've always been suspicious of that.

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 had this issue to. My S5 was restarting 6 or 7 times a day. Oh my was it frustrating um? I've had the phone since april also. I can say this my phone hasn't restarted in about 2 months. The problem is completely solved. Yes it may be an app an yes someone said unmount and remount sd pull battery and sim also. I can tell u wat I didnt do I didnt replace the battery sim or sd same parts as the day I got it. And ive never factory reset the phone so unmount remount everything and check your apps.

Yes and let me add I was using CleanMaster and that may have been the culprit those cleaning apps and battery apps are completely useless on a S5. Once I got rid of that my phone ran a lot smoother I hope this helps.

This is my thoughts, as I'm reading it seems to be just t-mobile.

It isn't limited to T-Mobile; I have the same isdue with Sprint.

I've had this same problem since October when I first got my Galaxy S5. Just about everything that has been suggested or chronicled here, I too have tried.
This is on Verizon. Just last week I went into their store and it just so happened that Lollipop had been released for Verizon-Android phones that morning. After upgrading to Lollipop, for two days it all seemed like it was working fine and then... reboot time again. I've reformatted, then replaced, then removed the sd card, all to no avail. I did a factory reset, and removed all 3rd party apps. I then was running in Safe Mode for a while and, alas, it rebooted. I, too, thought it might be WiFi related so I disabled WiFi; again it rebooted. Sometimes just sitting at my desk with the phone on my belt, it reboots. Driving my car listening to a podcast, it reboots. Formulating an email, it reboots. This happens probably three or four times a day most days, although occasionally it might skip a day or two. I'm now asking the fellow that helped me at Verizon to look into having it replaced. There are two co-workers in our office that have the same Galaxy S5 phone but without the rebooting. I assume I got a lemon and I'm hoping Verizon will have mercy on my soul.

So I got my S5 in June, and lately have been having the same problem. It only happened occasionally at first, maybe once a week. It's started happening once every day or two now, and it's rather annoying. One thing I've also noticed that's started recently, is that the WiFi stops working randomly. I'll be connected to the wifi, but randomly have no connection. I work in IT at a hospital, and I had it connected to the guest network, and at first I thought the guest network was down, and I started troubleshooting it, before I realized it was my phone. There was no indication of any problem. I disabled wifi, reeenabled it, it reconnected, and everything worked fine. This is in addition to the fairly regular stuttering using bluetooth audio in my car. I wonder if maybe there is a firmware or hardware problem with the wifi/bluetooth combo chip used in the S5.

I'm not sure if this will help a more savvy person, but it is, at least, on MY phone, something to do with LOCATION.
I have a Tmobile S5, with Tons of software apps (all from google store). I too have this problem BUT,
at Home and at Away locations ONLY. At work, no problem.
Work is Downtown Urban. no problems, no shut offs, no reboots, plugged into a samsung plug with samsung cable. (nromally between 9 am - 6 pm)
Away is a small office/apartment about 5 blocks away, use S5 as a wireless hot spot. not a samsung plug or cable, but seldom reboots. (between 7 pm-8am)
Home is suburban, about 11 miles away from downtown urban, use wireless calling inside, rebooted every 5 minutes to every 6 hours. (between 7 pm- 8 am)
Worse, when far away from wireless router.(Verizon Fios)
The problem on mine also seems to seldom occur in automobile, or anywhere in city. Not unheard of, but seldom.
It also seems to occur MORE often, when battery is lower. So, what do these things: Power, Location, wifi - indicate?
Any tech savvy guys there have a clue? (sounds to me like it is several different things, but there must be some reason why the home is the place, time, environment that causes the most reboots.)

Had same (Poland, Tmobile), reseting phone to factory settings helped me

Factory reset or update firmware

 

[Booderness]

My Verizon S5 constantly reboots. When I click the menu button twice, it shows all active applications. I had "active" applications from days and several reboots before. The problem seems to be that the device is out of memory so it reboots which should close the applications. However, since updating to Android 5, the applications are not closing even after reboot and are showing active. So until there is a fix, you have to hit the menu bar twice from the home screen and select close all, then reboot your device and it will stop rebooting until it runs out of memory again. Then repeat. Knowing Google, Samsung, and Verizon, it may be 6 months before a patch is issued.

I had this problem show up on my TMo S5, uninstalled a number of apps but didn't want to take the step to factory reset. I noticed that my issue was only happening at home where I was set up for 5Ghz wifi. I deleted the connection and connected to my standard 2.4Ghz SSID and the problem vanished. It's as if the Samsung firmware has a problem with the 5Ghz radio. Would very much like if someone else could proof this and see if they have the same result.

ATT S5 Active on 4.4.4 here. I've been having the same problem occasionally (a few times a week) since I got this phone (new) in November. Two days ago the problem got worse. My phone has been rebooting every 2 minutes or so while I'm browsing the internet, making calls, etc. It doesn't matter what I'm doing, it constantly reboots without fail (and drains the battery while it's doing it).
The issue does not stop in Safe Mode, but does stop when I remove the SIM card, so I went to the ATT store to replace the SIM. That fixed the problem for about an hour, but when I got home, it started rebooting again same as before.
I tried clearing the cache and doing a factory reset. That didn't help either. I now have no apps running outside of the ATT and Samsung crap.
I went back to the ATT store and strangely, it stopped rebooting while I was in the store. But as soon as I got home, it started again.
Thanks for the tip about the Wi-Fi. I have disabled Wi-Fi and so far, no rebooting. WTF does that mean? It's driving me crazy and I'm ready to smash this stupid phone.
I will update later with any new insights.

i had these issues for the last 1 week.

battery drained super fast, i tried to charge it but it took 15mins to get to 1%!!! and when i on it, it will go to 0% again within minutes.
I realised alot of background apps running even without me activating it. i suspect its Clean Master doing the trick. making us more dependant on it.
i since reset to factory settings, the battery problem is inda solved, but, the phone still restarts by itself without any activation by me. i can just leave it on the table and the next moment i hear the start up music being played.
this happens about 4 to 5 times a day.
i also suspect its the Wifi fault. I realised recently the wifi of my hp keep connecting and disconnecting and connecting again and again.

Wonder what could be the reason. After restoring to factory settings i did not install Clean master again.
this restarting is a pain in the a**

I am having the same issues. Sprint said to go back to manufacturer reset. Done. still happened. said too many pictures. ok, removed. need more memory, ok added new card. so now they blame on the apps. I have the same apps I did with my last phone and never had a problem. I am considering getting an iPhone.

 

[Booderness]

Problem Solved. I went back to 4.4.4 and everything is fine now.

Didnt read yhe the comments but if you have any type of cleaner battery doctor cm cleaner or clean master delete reboot to recovery wipe dalvic partition clear all browsers cache and history restart. Them cleaners efff ya phone up overheats it andtoo much b.s the only 1 thtz good is sd maid if tht doesn't work you have a bad app.
