S4 Random reboots!

Just bought a new S4 GT-I9505, for some reason it just randomly reboots! It did it 5 times in 10 hours. I tried resetting it to factory in case the apps I had installed were causing it. I don't think they were because as soon as it switched on again after being reset it rebooted after about 5 minutes.
Any ideas?
Could it just be firmware related and I have to wait for an update? Or is it hardware?

Do you have a microSD card in the device? If so, what kind?
Are your SIM-card properly placed into the device?

It's a 8gb San disk ultra micro sd and I have just removed and inserted it and my sim. Both are fitted correctly.

Anyone?

I'm assuming you are running stock (not rooted etc). Are you using the latest firmware? Have you checked for a system update?

Stock, yes. I actually restored through kies so am fully up to date. Checked for an ota to be on the safe side though and nothing.
It has only rebooted once since 9am this morning so it's improved on yesterday!

I had the exact same problem with my s3.
New or of box it rebooted randomly and always when
i stayed the programs first time.
I returned it and got a new. That is what i recommend.

Same thing happens to me.

Are you sending yours back?

if it stays on download mode try to flash a fresh stock firmware for i9505.. you can it from samfirmware.com.. it could help if it is due to a software issue,, otherwise its going to be a hardware issue..

did you try "wipe cache partition"?? sometimes it fixes some problem if it does not return, that s what i did with my reboot problem while playing video.

I'm having the same problem I cleaned cache several times and installed the cmw recovery again. Any ideas?
Thanks

Halp, random freezing and reboots, all roms and kernels.

Hi Everyone, i am getting random reboots and freezes on all rom and kernel combinations, sometimes it will happen 20 times a day, some times only a couple.
Anyone know what the problem may be?
Damaged bootloader or something?

OMG same here i get random reboots. though it hardly ever happens to me, nothing is affected and everything is fine, but its just weird. ive not tried the SystemServer Crash Fix in Wanam, though this may help. :good: when it comes to freezes it happens all the time to every device so no real explanation- at least not from me. though greenifying apps and de bloating and etc would help if this is consistant. - i my slef havent de bloated anything and only greenify apps. you could also try a factory reset.

I have tried wanam crash fix still the same problem, i guess its more than rom selection.
What do i need to flash to set everythinf back to factory factory, reflash bootloader the works.

I'd format everything in TWRP, system data cache internal, the lot.
Then power off the phone and it will warn you that there is no OS installed. Then boot to download mode with the button combo.. then flash the latest stock rom via odin
I use v3.09

Hey mate, I have a HK note, can't seem to find latest 4.4.2/4 firmware, so I tried N9005XXUFNF4_N9005OXAFNF4_BTU but failed on ext4 system etc... so i just flashed the latest N4 bootloader, flash twrp, a rom, same freezing issue.

Anyone else?

That's your problem then. You flashed incompatible software on a HK Note. HK notes are slightly different to the normal note due to software. Find the latest HK software and have a nose around the HK guides and read how to fix, it's a common problem (or it was once at least) and can be fixed, so don't panic too much

Ok cool thanks, i checked samfirmware and nudda?
I have previously softbricked my note when kk first came out and had to flash the chinese Rom / sweet from combo to bring it back, are you saying to flash that chinese rom again?
Im not sure what started the trouble as i was running xnote for a while perfectly.

I found this firmware on samsung updates "N9005ZHUENH4" flashed it, seemed to be ok for the last couple days, today I rooted the phone and boom, back to freezing and restarting.
I re-flashed BL, Modem + CSC from the HK recovery rom, but it wouldn't let me flash AP :s
I just flashed g00h s5 rom, I can't get past the inital setup steps :/
What do I need to re-flash the phone to totally factory, seems there is still something screwing it all up :/

herrrooo???

Have flashed multiple times, cannot shake this problem.

[Q] Lollipop random reboots

Hi
I just got this phone for my wife and all is well, but I have heard that the Lollipop update is quite bugged.
We are experiencing random reboots.. With twenty or thirty minutes interval...
Is the random reboots a known problem for lollipop or is it just this phone being a candidate for repairs?
Any other bugs I should be worrying about?
All best and thanks in advance..

Did you factory reset the phone yet? Upgrading to Lollipop from Kitkat leaves rubbish files behind that a factory reset fixes, myself included have reset and it has fixed just about everything

I'm running Lollipop and never had any random reboots. Its running very smooth here. If you updated from kitkat perform a factory reset after update.

Hi
It is the G900F nordic...
And The battery drain is insane...

What I would do; reflash the actual Rom via Odin.
If this doesnt work: downgrade to KitKat and back to lollipop again.
Afterwords everything should be fine. Dont forget to wipe after every flashing process.

Random reboots after nougat update

Anybody else's phone rebooting every few days..?
It hard reboots (Galaxy S7 edge screen), so i thought it might be hardware failure.
Haven't downgraded to 6.0 to check.
I don't have an sd card inserted (because the one i had corrupted which caused my phone to randomly reboot, now i took it out and it still does it)
Also, I noticed that every time it randomly reboots, the battery percentage drops significantly.
G935F, stock

Before you updated to nougat 7 did you do a full and complete wipe
which includes wipe system, data, cache, dalvik cache and last but
not least did you do a factory reset in twrp recovery before odin
flashing the Nougat firmware?
Are you 100% sure that you odin flashed the correct Nougat 7 firmware for your S7 Edge?
Flashing the wrong firmware can cause rebooting issues and fast battery drain.
Flashing without doing a full and complete wipe can cause rebooting issues too.
Good luck, have a great day!

well, i had a clean 6.0 install which upgraded to 7.0 via ota (UK BTU firmware),but thanks i suppose
(and i also factory reset 7.0 many times)

I am getting random reebots since nougat. I flashed the bell nougat (in on Rogers in canada) and then flashed the Rogers CSC. Things seem to check out so I'm not sure what's wrong. I am going to try to get the Rogers nougat files and see if that addresses the issue.

I have the same issue.... I have unlocked phone on a thai carrier

You DO NOT have to do a 'factory reset' every time you have an update, not even for an operating system update.
I don't know where this comes from but it's stupid.
These updates are designed to integrate with existing systems!
You are as likely to solve any issues with a few reboots.
If you have a problem it's likely due to software conflicts of an app you've installed, not the operating system. Android is pretty good sorting itself out.
So, you do a factory reset with all the hassle of trying to get things back to where you were and then you install another app which causes an issue and ...
Pointless as are the cache wipes always suggested. Android is good at managing resources.
At least with a cache tidy up you're not back to square one
I wished folks would stop suggesting factory resets at every opportunity. Mad.

I get them too, i`m on the lastest NEE software updated via ota. Randomly, when i get it out of the pocket, it says enter pin number because your phone was restarted, i`m using fingerprint lock.

Hello I have a Galaxy S7 and since the update to Android Nougat 7.0, my phone restarts randomly, it can stay an entire week without restart and it can also restart 2 days in a row. It's totally random. I have reset to the factory settings and I have reinstalled only the most important applications (facebook messenger, viber, yahoo mail) but unfortunately about ten days after reset, the problem has reappeared. What could be the cause of this problem? For info, the firmware version installed on my phone is: G930FXXU1DQBO. Also, I saw on SamMobile that the countries that received the update later, had a new version. Could the problem come from that? Is this a bug in the firmware installed on my Galaxy S7. Thank you in advance for your help.

Sadly I have the same problem. Oddly enough this is my first handheld which I didn't root and the first I am running into such issues with.
Got a OTA update to Nougat and I am getting almost daily random restarts.
I wasn't able to discern any patterns so far. Sometimes while it is charging, sometimes just being in my pocket. It doesn't run hot as if an app is running havok nothing.
So far I cleared the cache and that seemed to help but alas it started again.
Does anyone have an idea what is left to try? I would do a complete wipe, but others reported that it did jack for them so I am hesistant to try it.

Sorry for My bad English, i m italian.
Try to remove Chrome. The issues is there for me.
Bye

I have some problem. Not to mention battery life severely reduced after update to nougat. usually 5h screen on time to now 2.. max 3h. SAD.

Samsung Galaxy S8+ Random Reboots
Same problem with my Samsung Galaxy S8+ running Nougat. Purchased the phone from AT&T and received it 3 days ago. It randomly rebooted twice so far, once when I was looking at photos and once when using the play store

I have the same problem. It is completely random, it can happen every 2 days or once a week. Even after a factory reset, this problem of random reboots still persists. The firmware version is G930FXXU1DQBO and I still have not received a new update. Have you solved your problem?

Do you reset your phone to factory settings? What is your firmware version? It seems that the old versions are not very stable.

No, the problem is still here, i did not receive any software updates so far. Sometimes it reboots even twice a day, random, sometimes 2-3 weeks without reboot. Waiting for ota update, maybe it will solve it.

After receiving the February version, did you receive a corrective update? If this is the case, it may be the update that has solved your problem.

Had the same problem on stock ROM, but the last update with january security patch fixed it.
Maybe a factory reset fixes the issue?

I did make a clean install through TRWP. WIPED cache and dalvik cache. deleted internal data and system data.
I had random soft reboots before I was on fulmics Rom as well. so I think it's not specific to this Rom....
how many times did your device rebooted?

On which base is Fulmics yet?
The reboots happened once a week, or sometimes even twice a day.

I had this happen on stock. After much reading of logcat output I was able to determine some kind of system table was getting exhausted. Proceeding on the theory that some app must be misbehaving to cause this, I disabled or uninstalled as many apps as I reasonably could, concentrating on what I could remember having installed or updated recently, and the reboots went away (I am paying close attention as I gradually re-enable or re-install stuff but haven't found a definitive culprit yet).

I had the same thoughts.....cause the issue is not taking place continously.... so I don't think it is ha hardware issue.... still couldn't find the app which may lead to a random soft reboot
