[Q] Galaxy S4 restarts every 10 minutes

Well for starters, high everyone!
I have an issue with my S4 and I've searched all over but none of what has been recommended helps.
The issue I have is that my phone will restart about every 10 minutes (give or take). I used Reboot Logger to determine this. The phone only restarts when it is idle. It WILL NOT restart if I am using it (screen is on). The weird part is that it doesn't even go through the whole reboot sequence. The screen will stay black the entire time. The notification button pulses and the home buttons will light up like it was restarting though.
I had a bad battery and had it replaced with a stock Samsung battery. I've tried pulling the SD card, pulling the battery for 10 minutes, pulling the battery while the phone is on, and I've performed two factory resets.
The one thing I have noticed is that, after performing the factory reset, I get an "error" under the little android dude. This also happens if I do a cache wipe.
My model is the SPH-L720 running on android v4.3. The phone has never been rooted and there are no software or firmware updates that are found.
I was beginning to think that this was a hardware issue but the consistency in reboot intervals makes me believe otherwise. At this point I'm at a loss. I rooted my old phone but my experience in that area is very limited. I have read that the cache partition is bad from the factory on some of these (hence the error message) so I was thinking about rooting the phone and trying to use a good cache partition, but that's the only other option I could think of.

sounds like a voltage prob....or mem prob... id redownload a new rom..wipe wipe wipe..reinstall and that should fix it

Insufficient voltage at idle was my first thought too, but if you haven't undervolted (since you aren't even rooted), that seems less likely. If I were you, I'd root the phone so I could do more to figure things out. Maybe try bumping up the voltage a little on the lower clock speeds.

Ok, first of all, do not root your phone. As you admitted yourself, you have limited experience in this area, and there is nothing that rooting will do for you. Not to mention, if you think you have a bad cache partition, you don't need root to fix it. Your phone is stock, running the stock kernel, there is no reason to suspect voltage issues that are not hardware related. If you root the phone, you will likely trip KNOX, and void your warranty.
My personal opinion is that your phone has a hardware problem. If you want to truly start over, either recover your phone through KIES, or better yet, download and flash via ODIN a stock MK2 ROM from this forum. Since this is a stock, signed ROM, you will not trip KNOX, and it will rewrite every partition properly on it's own. This is all assuming you don't have a hardware problem. But do not go ahead and try to fix anything yourself besides what I mentioned. You will not succeed, and likely lose your warranty in the process.
Edit: did you buy this phone new or used? If you bought it used, more than likely somebody ruined it for you. And more than likely, you can fix it. If this was a new device, more than likely it will be a warranty issue. That's why you shouldn't do anything to void the warranty.

If you're going to use odin for anything, just make sure you follow someone's directions step by step. Otherwise very bad things can happen.

im also having a slightly similar problem
Problem : The screen after a sleight amount of time of being on, or sometimes instantly when opening the lockscreen it freezes for 10-15 sec then shoots black lines across it, then reboots.
Things ive tried :
1. Installing a new rom ( from AOKP 4.4 and Triforce 4.3)
2. Changing modem (from MJA, MK2, NAE)
3. Changing the type
of Gapps i was using. (4.3 gapps for triforce, aokp 4.4 gapps, and pa gapps)
Current Phone Info:
Rom: aokp_jfltespr_kitkat_nightly_2014-02-08
Modem/Firmware: NAE
Gapps: Pa.gapps 4.4.x
Let me know if you need anything more! plz!

I'll look into Odin before I root. The phone was also purchased new. I spent most of today monkeying around with different settings to see if I could trigger the issue as well. As it turns out, the phone will only restart at idle if it's plugged into the charger, or the wifi is on. If wifi is off and it's not plugged in it's fine. I am also using the stock Samsung charger that came with the phone. Again though, if I'm actively using the phone it doesn't happen (charging or connected to wifi). I did turn the phone off earlier to charge it but would keep freezing at the sprint logo upon boot up. I thought it was bricked for a second... I wiped the cache (didn't do a factory reset) and that fixed it, but now I have that stupid issue where videos won't play on wifi, only on 4G or 3G. It's an issue I thought I had solved.
Le sigh. This is frustrating. The Odin option is looking to be my best bet it seems.

Since you are running a custom source-built ROM, first thing to do would be to ODIN a stock ROM. If the problems go away, you have your answer. If not, this would likely be a warranty issue. Of course you tripped KNOX most likely already.

Alright I'm a little confused as to what exactly I should be using. I found this:
http://forum.xda-developers.com/showthread.php?t=2575470
which is a stock ROM. Although I also found this:
http://forum.xda-developers.com/showthread.php?t=2259513&highlight=odin
which is the stock firmware.
Which one do I use, or do I use both of them?

Follow instructions in the thread. This is a completely stock rom with no root or mods and will not trip the Knox bootloader. If you flash anything other than this, including custom recovery, cf autoroot, etc, you will void your warranty.

rebooting
i had this problem once and it was related to a corrupt file on my sdcard believe it or not. there are Defraggers out there for your android file system and internal SD card but your Ext sc you would have to do on your PC. it worked for me. the one i used is called CLEAN i got it off amazon app store.

That solved my problem, thank you! I spent the last couple days testing it just to be sure I wouldn't be crying wolf. The phone has yet to restart on me even while charging or using wifi. The error message I would receive after a cache wipe or factory reset went away as well. It makes me wonder if the bad partition was what caused my old battery to fail.

Great, I am glad it worked out, and hopefully your problem is resolved. I doubt that your old battery failed due to a bad partition, and I have to wonder how your partition got messed up in the first place, but that's just a curiosity and is irrelevant in the grand scheme of things. Just remember that if you decide to root, cf_autoroot works but will trip the KNOX bootloader and potentially void your warranty.

[Q] Reboots after Lollipop

Verizon Note 3 here, I received the Lollipop ota today and thought no harm in taking it as I was already stuck without root on 4.4.4.
It worked ok for the first couple minutes, then a reboot, then same thing, about 5 minutes and a reboot. Sometimes ~2 minutes, seems using it in any situation made the reboots happen. I did a factory reset thinking that would clear things up. Unfortunately now it is even worse, as it's rebooting anywhere from the first touch to the screen, to about 15 seconds of activity, literally dozens of reboots.
I downloaded the update on my pc and installed via Odin hoping that the ota was just corrupted or some bad luck like that. Nothing changed at all.
It will idle after booting just fine, I just can't do much of anything, every touch of the screen feels like a roll of the dice. Every few reboots or so I can make it to settings maybe but haven't been able to actually change much of anything, not that it would seem to matter here.
I've flashed via Odin twice, cleared the cashe many times, factory reset 3 or 4 times. Am I screwed here? What else to try?
*UPDATE* I flashed back to 4.4.4 with Odin and no more issues. It appears that my device alone is completely incompatible with the new firmware.

I should also note that I tried airplane mode, safe mode, and removing the sd card with no improvements.

After hours of messing with this thing and nearly giving up, not half an hour after I post here for help, I seem to have found a solution, although hopefully not a permanent one. The problem was happening when I would touch the screen, not scrolling ever, but making selections. On a whim I turned off sound and bam, no crashes.
I would still love it if someone had some insight about this problem, or better yet a solution.
I'm not sure yet if it is just the keypress sound that is killing it, or all sounds. I never did have any issues with the stock keyboard clicks now that I think of it, only the menu press sound. In any case it's not every time it made the sound, just half the time or so. Anything anybody could add to this would be appreciated.
*Edit* Not a solution, but it did help.

Well it's not as stable as I'd hoped. More like before the first factory reset now, but still not good at all. The various sounds definitely trigger crashes quickly(menu options, volume pings, mp3 songs from sd card), but regular silenced menu presses do sometimes as well still. Phone also bootloops several times often before it can get booted stable and 100% always crashes immediately if I try to unlock the screen in the first 5-10 seconds after booting up. Not sure if I'll be able to call or text as it's too late to test that atm. I'll update tomorrow, any insight appreciated.

I would say a bad download but I don't remember if ODIN checks MD5 sums (pretty sure it does). I would do a full wipe and reflash the stock image with odin

I am 100% stock not rooted never been rooted 5.0 vzw and I have had a couple of reboots. Never ever had one on this phone before. My old note 3 was rooted but I got this replacement after the root exploits had all been closed.

ehh not all have been closed

What is the root exploit for Verizon Note 3 with 5.0?

None at the current time but CVE-2014-8609 seems like it could be some use

I spoke too soon when I said the phone was usable now. At best 5 minutes of light use as anything seems to crash it now. I did get a fresh image and used it with Odin with exactly the same result which makes me think its my phones hardware or something. Just seems crazy that it was working just fine before the update. The reason I pushed to 4.4.4 and lost root is because my phone suddenly started an issue where it would crash when making or receiving calls. It wasn't caused by any new apps or anything, just out of nowhere. I tried everything then updated as a last resort, carelessly I went to 4.4.4 instead of staying at 4.4.2 and lost chance of root, but it solved the problem I was having. I wonder if the issue is related somehow.

I was able to odin back to 4.4.4 and it's working fine so far, I assumed that you would not be able to revert back like the last ota and just tried it as a nothing to lose last effort. This is very important news to anybody that is having major issues with 5.0. Maybe, just maybe I'll try it again if they make an update patch for reported issues.
But for now, 4.4.4 it is for me.

VZW Note 3 update to Lollipop
I just finished the Lollipop update and my phone is working great for the past 30 minutes. Seems a little slower then usual but have had no issues besides my phone locking up after downloading the update, may have been due to my phone running down to 14%, but after removing the battery for 20 secs and putting it back on, phone came back on, I plugged into charger and started the update. Will post later if I have any issues.

I have been trying unsuccessfully through odin to downgrade but it keeps failing in odin, I downloaded the official firmware from sammobile.

Just curious if u r tried reinstalling newer odin? Try different USB port and cable. At this point maybe even try different pc if u have access to 1

SM910F Note 4 5.1.1 Random Freezes and Restarts

Hello there xda.
I have a Samsung Galaxy Note 4 SM910F.
So what is happening to my phone is that whenever I am in any random app lets say reddit or even chrome for example. It will like freeze for a minute or two and then unfreeze.
In more extreme cases it will reboot.
So this happened randomly because I flashed a Stock unbloated 5.1.1 ROM from here back in december and everything was working smoothly and stuff. I had xposed installed and all my apps. Then in February it started with this random freeze/reboot. I had not installed anything else apart from what I had for the last 3 months.
So I restarted the phone, changed the battery and stuff to see whether that will fix it. However it didn't. So I formatted the phone (the soft type) just so I can install another ROM. So I tried another ROM, flashed the correct CP and BL and stuff and then just installed chrome and whatsapp. After an hour or two the same thing happened. So this time I factory reset he phone, like a complete wipe and I installed the unbloated ROM once again with few apps. Same thing happened...
So my last resort was to install Cyonagen Mod. After an hour or two same thing happened...
I don't know what is the problem. I read about some peoples phones emmc failing and thus the freezing, but I am not sure yet.
Please could you guys explain what I should do to fix this?
Thank in advance!

I have the same problem. Starting on mid january. I'm on stock 5.1.1 with root and twrp recovery
Tried backup and factory reset

I went back to stock after I factory reset the phone. And still had the same problems.
People say that its a hardware problem... So I guess I'll have to send it back to Samsung soon.
I think I tripped the knox. I just have to unroot and get it back once again to stock and send it back. I hope that they accept it.

i have the same problem. my model is SM-N910W8 and I bought it from 2nd hand, so no receipt and no prove of purchase.
can I still send it back to samsung to fix it?

same problem as you and now my phone died completely .
my phone was 4 months and he has not supported any longer he died naturally lol.
my operator gave me another free under warranty because the phone had a faulty motherboard and after several back galaxy note 4

This started happening to me a week or so ago and my phone just got stuck in a boot loop after it froze and rebooted. I'm on the latest stock firmware. Tried factory reset, reflashed stock firmware, nothing helps. It still reboots (sometimes it almost gets booted completely, other times it reboots after 2 seconds.

Just disable finger print. Yes that magic feature offered by Samsung is causing more hungry that happiness since S5

Many thanks. This was driving me mad for a few days, I had tried three different ROMS, completely wiping everything. I eventually went back to stock, which I'm still running and it was the same; it would run fine for a few hours and then start to lock up until eventually it would either reboot or stop responding and I'd have to pull the battery to restart it.
Just not selecting fingerprint security doesn't work, you have to force stop "Fingerprints" in Application Manager (All).

just do not setup the finger print lol. I was having those problemes too when I bought the note 4 until someone tell "do not setup the finger print" lol, not I'm a happy user.... I hope that android 6.0.1 solve the probleme

Galaxy S5 Stuck On Splash Screen with Set Warranty Bit: kernel ---please help

First post, So hey everyone
So I rooted my phone around 6 months ago with CF Auto Root, everything went fine but i was still on stock ROM. So then i found the Alliance ROM and decided to flash that because it looked cool. I flashed it using FlashFire to ensure I keep root. Everything worked and booted just fine, really smooth and of course it looked awesome. One small problem though, I could not send messages but I could receive them. Probably a SMSC (that was around 3 hours of head ache attempting to fix that) issue or because Straight Talk didn't like my phone using Android 5.0. So then I tried downgrading to Alliance 4.4.2, NOPE. That was the end of my phone :'(
Im now stuck on the Galaxy S5 screen with "Set Warranty Bit: Kernel" in the top right. No idea how to fix it and obviously knox was tripped but that isnt a huge deal to me.
I have tried the following.
1. Tried to reroot (seemed to fix a lot of issues actually)
2. Tried to reflash Alliance ROM android 5.0
3. Multiple cache and system wipes.
4. Installed TWRP through Odin but thats useless because I was dumb and deleted my back up in the system wipe
Im currently downloading stock ROM but my hope for that is fading judging that TWRP even stalls out and the phone reboots right when it attempts to flash. - well this was a bust, there are 4 freaking md5 files. when i go to flash with odin it says it a modem and then fails
What i have access to:
1. Recovery
2. Download
Is my phone already 6ft under or is it hanging on for dear life?
Edit: Should also mention that my galaxy is a SM-G902L (Straight Talks' model???). CF Auto Root for Galaxy SM-900F was used to root. So that is what i based my choice for model when installing Alliance
Ok so recent update, When I go into reboot and do system or whatever, it says there's no OS installed. I guess that would make sense why it doesn't want to boot, because there's nothing to boot into... but why cant i install any OS through odin???
Another Update: So I have no OS, I know how to flash a new OS, such as a custom ROM, but my phone refuses to accept the flash whether through odin or through TWRP.... W.T.F. Did i really look my phone down? And I guess that means that I will need to get the Straight Talk variant of Android 4.4.2 Great If anyone has the a backup and they are on straight talk, please help me out
Thanks for the help!

FIXED!!!
So after around 14-16 total hours of headaches, I have managed to bring my phone out of the grave. I read over the Straight Talk Variant Galaxy S5 thread multiple times and saw people saying that most Verizon ROMs work decently if not perfectly fine with the SM-G902L. So I downloaded M.O.A.R ROM and flashed through TWRP.
Worked like a freaking charm!! She booted right up, into the waterspout boot animation, and after a very long 5 minutes, I got to the welcome and setup screens!! I guess it was just a matter of finding the right ROM. I just find it kind of weird that it would flash Alliance just fine and then not allow it the second time...
Anyway, the very helpful thread that saved my phone

I337 extreme lag, random reboots, no recovery

Recently bought a new out-of-the box Galaxy S4 I337 from Amazon. Had i known how much trouble it would give me, i would have picked something else. When i first turned the device on, it was almost totally unusable due to lag and random reboots. Software version was 4.4.2. I used Odin to flash a rootable NB1 onto the device. Still had lag and random reboots. Upgraded to lollipop using this guide: https://forum.xda-developers.com/galaxy-s4-att/help/guide-att-samsung-galaxy-s4-sgh-i337-t3383078 and still have lag and random reboots. Also, the first time i upgraded to lollipop, i installed safestrap not knowing it wouldn't work on lollipop. Obviously, my recovery disappeared. When i figured out what was going on, i did a fresh install of lollipop. I got recovery back, but today when i tried to boot into recovery to wipe the cache, i discovered it had mysteriously stopped working again. If i attempt to boot into recovery, it just skips to the Samsung logo. I didn't install safestrap or any other custom recovery this time.
When i turn the phone on, either it hangs at the AT&T white splash logo and refuses to load at all, or advances to the lock screen. I have disabled animations and every widget i could on the lock screen and yet when i attempt to unlock the phone, it usually freezes. If i repeatedly swipe the phone for thirty seconds or so, it unlocks but it is still frozen and i have to continue swiping to prevent it from locking again. Eventually i'm able to navigate the phone normally, until it randomly reboots or freezes. Sometimes i see an error message that Touchwiz home, Process System, or SystemUI has stopped working or is not responding. This is always accompanied by a freeze. Also, choosing an option in the dialogue that comes up when i press the power button (shut down, reboot, etc) invariably causes the device to soft reboot. Other times a soft reboot happens totally at random, even if i'm not doing anything. Anybody have any idea what's going on or did Amazon just sell me a dud? All of these issues have been happening since before i rooted the device or upgraded it, except for the disappearing recovery mode.
Thanks in advance for your help.

Sounds like a data factory reset is in order. First you need recovery back so I would odin the latest firmware for the phone that can be flashed in odin. If it's still messing up then get Amazon to replace it.
Since you have safe strap though, try booting a TW based rom like Thor ROM or Golden eye ROM. That may fix some things.

Just wanted to bump this to thank you for your reply. Never got the phone to work but i was able to get it back to stock and return it. I got a refurbished S5 instead.
