Samsung Galaxy S4 keeps restarting!!

[Vikash Patel2]

Same thing was happening to me. Phone kept restarting.

I noticed that my battery would slip pretty easily in & out without having to push it up and in. So I wedged a piece of folded paper on the bottom (opposite of the contacts). Turned the phone on. and no issues yet. I believe the battery was losing contact (by sliding ever so slightly) with the phone terminals and shutting off.

This may be due to the battery slightly bulging or changing its shape ever so slightly that the fit is compromised.

I'm having the same problem!
I've already reset my phone to factory settings. Didn't work!
Removed the micro SD card, installed the Battery HD application to check the battery status. Shows everything is perfectly fine!
Now this has somewhat slowed down the inevitable restarting, but not quite resolved the issue.
Help needed!

I'll just let you know that my screen (bended by a bulged battery) and the battery itself are both replaced under warranty (SGS4, Finland). So if you have those battery problems and the phone is still under warranty, just go and ask them to replace the battery before any further damage will happen.

Hi,,

Replace the battery - this solves exactly the same problem for me

My SAME problems with all of you started after playing games on my S4. As u've all noticed, playing games on wi-fi kills your battery very fast and u 'll soon need to plug your phone on the charger. Now if i want to play games i'll have to HAVE IT PLUGGED, as this is the only way to not having such problems. Also plugging it in, IMMEDIATLY STOPS the continue rebooting of the phone and u can start it with no other actions ( SD cards, SIM card, Battery off etc ). I think our batteries are worthless and they're the ones responsible for the poor results our phones are facing.

How long did it take to replace the screen? And what was the process like.

My screen has bulged due to a swollen battery.

I have had my s4 for some 4 months now. Had no problems until just recently. It seems fine when listening to music but as soon as I start to surf it shuts down completely. I have taken the battery out. Did nothing. I did a factory reset and took off all third party applications but it still happens. Battery depletes from 80% down to 0%. Any help would be appreciated. If it is a battery issue then would replacing the battery sort out the problem. Is there any way to check if the problem is with the the chipset in the phone itself?

It was just few work days. I took my phone to my service provider on 21[SUP]st[/SUP] Dec, its status was "Fixed" on 28[SUP]th[/SUP] Dec and "Ready for pick up" on 31[SUP]st[/SUP] Dec. I finally got it back today (7[SUP]th[/SUP] Jan) because I was out of city on holiday. It seems to be completely fine now!
They basically just replaced the battery and the screen, nothing else. They didn't even reset my phone to factory settings, which was actually quite nice.

hey..i just wanna ask you..if i sent my phone to the factory,do the factory will format the phone??or just fix the system??

 

[shebuck]

Same issue!! One guy talked about the SD card being the problem. I just looked and mine is not recognizable. It all started yesterday when I plugged my phone into my Mac and tried to transfer over my photos...and it WOULD NOT TRANSFER. It was freezing and everything was going wrong. So I stopped trying. Now I come to find that my SD card is not working...so basically, my trying to transfer my photos from my SD card caused it to not work and reboot my phone every few hours. Awesome.

I am having the same trouble with my S4. I have tried all of the suggestions listed above but none have worked (for long). Thanks to everyone who has posted these suggestions. If I find any information that may be helpful I will post it. BTW...I moved from an S3 to an S4 b/c of phone problems. Seems like Samsung's quality is slipping.

So you're saying that you sent your phone to the mainentance, but still having the same problems? They changed the battery? Reset the factory settings? Updated the software?
Hard to believe, to be honest.
But: if you're still - after mainentance - having the same problems with the S4 which is under warraty, just sent your phone back to the factory/service provider/who ever is taking care of these things there. If they're not able to fix it after trying few times, they should give you the new one.

It happened to me too. Battery indication would be misleading, saying some whatever 20 or even 80% battery left but would auto reboot following any use of the phone. Most people already went in depth about the problem.

The source of the problem, as already mentioned, is the battery itself. Samsung already admitted 'some' battery (well, a batch or more?) was faulty, prone to swelling and rapid draining. They are replacing it free of charge at any Samsung service centre (A quick google search should help to find it)

Thus, solution would be to change the battery, unless if the battery swelling out-bulged the phone (Screen or cover) and causing some internal hardware damage too.

You should not ignore other possible cause of the problem though, such as apps or SD cards but I take it, most of us here already ruled that out but either doing a factory setting or removing the card.

Thanks for the link which ultimately led to an online chat with Samsung Germany who will send me a replacement battery.

All of you guys with these symptoms should take a look at their Lithium Ion accumulator to see if it is swelling up (mine was).
Here's the final part of the chat:
...
[16:26:43] Heike, Kundenberaterin Mobiltelefone:
Vielen Dank. Ich habe f?r Sie den Austausch-Prozess angesto?en. Ihnen wird zeitnah ein neue Akku zugesandt.
[16:31:55] Robert Jones:
Berbesserungsvorschlag: Samsung k?nnte viele Kunden mit defekten Batterien Zeit und Sorgen ersparen wenn das Problem mit schlechten Akkus in Galaxy S4 ver?ffentlicht wird. Nochmals Danke.
[16:34:04] Heike, Kundenberaterin Mobiltelefone:
Vielen Dank f?r Ihren Hinweis. Wir tauschen anstandslos aufgebl?hte Akkus aus.

I had the same problem.

Take out your battery and check if it is swollen (put it on a table and spin it, if it spins on its back like a 1980's street dancer, it's swollen).

It's a very common fault with S4's. The new Samsung Batteries are rectified, just go to your service provider or a Samsung store and they'll replace it.

If your accu serial number starts with 'BD.....' you will get a new accu at a samsung service center.

 

[Andrew Baker2]

I have the same issue and three of the four people I know have the phone have the same issue. After spending a number of wasted hours in service center, the solution for two of them was to sell the phone and buy iPhone...

 

[primaryprime]

Hi,
Had the same problem. Factory reset, re-installed apps but the turning on continued . . Noticed a "Damaged SD" message and Re-formatted it, but didn't work.
THEN, removed the SD Card and inserted a new one and All OK, problem solved.

 

[Desarae McLaughlin]

Thanks for your suggestion. I just installed it on my phone.
The temperature is 34.2 C (I'm not sure if it's good or not) and the battery health is Good.
Is there a better health status for battery? Like very good,...?

Temp is normal. yes, it gets better. "excellent", i believe, is the best your battery can get. I would take it in. Mine has done it a couple times while a lot of apps are running at the same time. But it's not something that's suppose to happen.
Tip i learned from a T-mobile guy - so i can't say how reliable it is - to check your battery yourself, put it on a flat surface and try to spin it. If it doesn't spin somethings wrong with it. (That's if it even IS the batterys fault)
