Samsung Galaxy S5, reboots after update - Galaxy S 5 Q&A, Help & Troubleshooting

Hi.
I have updates my S5 to newest android.
A few times every day it reboots itself when pressing the power button to unlock the screen.
I have cleared cache and done factory reset many times.
No encryption, no pincode.
How can I fix this problem!!

Same here..
i`ve allready reflashed my phone twice with Kies...
Now i`m searching a way to downgrade it to the previous version.

Ugh :/
I have contacted Samsung support

Ejected SD-card, cleared cache and did a factory reset. Everything works perfect. Seems like android 6 or/and an app was causing the issue?

Phone keeps restarting

Hi all,
So my phone keeps restarting its self, sometimes it does it 2 times in 10 mins and sometimes not for a couple of hours.
I have flashed 2 different roms with complete wipes (wipe data factory reset/ cache/ dalvik and system) and the only thing i have restored from titanuim is apps + app data.
Never had this kind of issue with my s2 or s3 and none upto now with my s4.
Any ideas what it could be or what i have to do?
Appreciate any feedback, thanks.
No one can help?!
When i said i have flashed 2 roms i meant i had the issue suddenly and have flashed to different roms since the issue started and still its the same.
So im guessing its not rom related?
Don't do the restore.
Re-install all your apps and see what happens then.

Sluggishness after Lollipop?

I am in the UK, yesterday connected to Kies, Lollipop update was available so I downloaded and installed, the phone has not been happy since, pressing the home button causes a redraw. I went to make a phone call today, from the time I hit call until the actual time it started dialing was 7 seconds.
I am aware a factory reset might cure the issue but I'd rather it was a last resort as can't be bothered reinstalling everything. Does anyone else have this issues?
Unfortunately, only factory reset could help. This is maybe the only problem upgrading to Lollipop. Since it uses ART as default compiler where KitKat used Dalvik it is very difficult to upgrade without any problems. Because of that factory reset is recommend so Android can install every app for first time and not having any problems with Dalvik cache.

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.

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.

Freezing and rebooting

Classic "my phone keeps freezing and rebooting". I am quite in the know about flashing roms and such.
It started on the stock firmware 6.1.1 (i think it was). I dd factory resets, cache wipes the lot. It would still randomly reboot.
So i flashed Telstra version of 7.0. Still froze every now and then. Did the same things as above.
Flashed TWRP and wiped everything, flashed Renovate Rom and the bootloader for it, Still did it. Numerus factory resets and wipes of everything. It would freeze at any point from startup, to having setup the phone and making phone calls or on facebook or whatever. It would even freeze in twrp, or loading twrp.
I found that the data partition was corrupt so i re partitioned to ext4. Still nothing. I reformatted every partition so the phone was a complete brick with nothing on it and after flashing clean again it would still do it.
Whats the issue that I'm missing, or is there a way to log so i can find where it keeps getting stuck? It gets hot and blue light flashes and i have to hard reset it or sometimes i have to let the battery drain so i can turn it back on again.
pls help?
Hmm i will give you an advice so you dont have to wait for your battery to drain...just press volume down and power button for like 5 secs and phone will force boot. Anyway back to your problem...did you tried flashing latest stock samsung firmware?

This advice doesn't work with my phone even with holding the buttons for 30 secs and more. For rebooting I can only wait until the battery is completely drained. With little hope for another way shortening time to the next reboot any help is appreciated.
Same here...experiencing the same prob...
Same problem.

Sounds like you need your motherboard replaced i had the same issues on marshmallow thought the nougat update would fix it but realized it was a hardware fault not software..left it in store to get fixed and on repair sheet it said faulty motherboard..

As i know some S7 have motherboard hardware problem, mine has too, what help? warranty and they replaced motherboard. But if you root, you can say good bye to warranty, they look at knox first with this problem.

Touch screen not working - fixed twice after multiple factory data resets

Hello. I have a recurring issue with a 6P I bought for my daughter. Twice her screen has stopped responding to taps or presses. The problem persists even after a factory reset. The first time, I fixed it by wiping the cache partition in stock recovery after the factory reset (I know, makes no sense, since the cache partition gets wiped during a factory reset). The second time it happened, I had to factory reset and wipe the cache independently 2-3 times, and luckily it started working again. I'm not sure whether the resets or wiping the cache did anything, or if just restarting the phone multiple times is what fixed it. Either way, I don't want to buy another phone for her if I can figure out what's happening with this one.
Her phone is a Google Nexus 6P, stock everything. Unrooted & locked.
Note: After happening the first time, and finally getting it to respond, I set her phone up from a cloud backup. This time, I set it up as new. I really don't see how it would matter, as the problem persisted after a reset, before setting up the phone again. I guess I'm leaning on multiple reboots solving the problem, but just don't know.
Any help would be greatly appreciated! Thanks!
