Tracing cause of reboots? - ZTE Axon 7 Questions & Answers

My phone seems to like to reboot itself sometimes at night. Is there any way to track what's causing the reboot?
I'm using an A2017U which is BL unlocked and rooted, running on Nougat B15 and this rebooting has only happened since the upgrade to B15.
Previously I was BL locked and rooted, running Marshamallow on B20.
Overnight, I run two apps, Sleep Cycle and a White Noise app in the background. The phone lays on my bed, not touched by anything so I'm not hitting the power button or anything.
At first, I found that my apps were getting stopped at random times at night. After some investigation, determined it was the power management doing it, so I turned that off.
Now, instead of the apps getting stopped, I'm waking up to have to enter my PIN because the phone got rebooted overnight. This doesn't happen every night, just randomly.
I have never seen it happen during the day, it always happens sometime at night, after I've put the phone down and I've gone to bed/sleep.
Is there some way to track specifically what's triggering the rebooting?

Random Shutdown

When my phone is sitting idle (screen off) it will randomly decide to power itself off. Has anyone else noticed this? Any ideas on what could be causing it?

you mean randomly power itself ON, right?
if that is the case, it's normal, it just mean it woke up to connect to the internet, to get updates of news, emails, or whatever it was scheduled to pick up
nope. i mean it randomly turns itself off. this topic is being discussed over on the att captivate galaxy forum section.
interesting, so it's going from stanby mode, to complete OFF... nope never seen that happen to my i9000 model
yep totally powered off... completely sucks... looks like there are a bunch of ppl that have this issue with the captivate on att. $10 says its some lame piece of software that att puts on your phone that's causing the problem.
it's possible, i've read here a few users having crazy power issues (battery draining very fast) with their SGS i9000, but after wiping it out clean, to start anew, then the power problem is gone away.
so yes, a software could cause something weird like that.
Factory reset and so far so good
Hey guys,
I use a Galaxy S here in Hong Kong and I had the same random shut down issue constantly happen when my screen went off...
I tried everything, check temperature of cpu, etc. etc. and nothing worked, it just got worse and worse.
I even changed the battery to use the spare one that came with this. Still problematic.
Used SET CPU to limit the cpu to 400mhz, still problems.
Finally I did a factory reset and so far so good.
I only have the original system installed with the Remember the Milk app installed.
24 hours, no problems.
Installed AppBrain app.
Then I installed 3G WatchDog
12 hours, no problem.
Then I installed Paperdroid
12 hours, so far no problems at all.
If I run into an issue I'll post it here. But I think it definitely was a software issue.
Update - it randomly shut down on me
Alright guys, it shut down on my randomly today in the afternoon......
I dont know if it's the re-charging that screwed it up?
Because after my factory reset, last night was the first time i charged it....
Hmmm
This happened to me too - two days in a row until noon it would shut down two or three times - i uninstalled SetCpu and for now (24 hours) it hasn't happened again. I am not sure if it was the one responsible but it started happening after i installed two programs and i uninstalled them after it started happening. I uninstalled Visual Task Switcher first but on the next day it turned off again, then i unsinstalled SetCpu and it hasn't happened again - maybe some wrong profile settings but i didn't feel like experimenting
I had this issue once too in about 40 days.
I was reading an sms and then i turned into standby and put it in my pocket. Later, maybe 40 minutes i came home and my phone was completely off. I do not remember if i had to take out the battery before to get it on again.
I was wondering why it happened. Maybe it was caused by an app i had opened. Battery still was at 40%.
But since it only occured once in 40 days i doesn´t bother me.
Interesting you mention this as it just happened to me today for the first time. I took it out of my pocket and wtf? The phone was off. Very strange... Using the i9000 on the stock Eclair rom.
Should send back for warranty

software clash?
Well the phone suddenly switched off for me, but this time I turned off APPBRAIN and so far so good.
In fact, I came across an app called NoLED and since it kind of keeps ht phone on, while I have it on my desk, I'm able to be notified of stuff and so far with that, the phone hasnt' shut off.
I'm still experimenting with what works, but try turning off AppBrain and see if you still have the random shut off issue....
i use app brain all the time to keep my apps in sync
not the cause of the problem, that's for sure
my phone can last a whole day even with app brain running
OP, do you have MSN Talk installed on your phone? I have this same problem, seems to happen more when I am running MSN talk in a low signal area.
«try a new sim card. «Could be faulty. «i am on my 3rd phone and all of them had this same problem. «i bought a new sim card 4 days ago, and hasnt happened since. «but then again, this problem usually happens to me once every 3rd-5th day anyways, so i dont know if i am in the clear yet.
Me too, shutdown everyday
Hi guys
After upgrade OS to I9000ZSJG4, Phone random shutdown everyday.
Yep still shuts down
Tried keeping AppBrain off, still shuts down.
Used NoLED so the screen kind of stays on, still shuts off..
So far shut off on me after 40 hrs... this is really stupid.
I am this close to taking it back, but I genuinely think it's a software issue than a hardware issue...sigh
Anyone have any luck figuring this out?
Same problem no solution yet
Hi
I too have the same problem, haven't found any solution yet.
The temperature etc is all good, there is no pattern in shutdown issues.
I have tried factory reset and no new application, it still shut down while using in built browser.
I had the same thing happen to me while skiing in Whistler last weekend. It died twice. I attributed it to the cold. I normally use a 3000mah battery up there, but left it back the house that day. Afterwards while charging in the car and even charging it at home it died prematurely again. It was the eBay aftermarket variety 1500mah knock off. I have since changed back to the Samsung OEM battery. I haven't had an issue with it since. My assumption is that the knock offs in my case cannot handle the heat cycles of charging and then the cold as well as the original. Or they have a limited lifespan, well below OEM specs. I am now only using the 3000mah battery on the weekends to hedge my bet on the quality of manufacture, as it seems to be from the same factory as the 1500.

4.1.83 - random reboots a thing of the past?

I realized today that I hadn't had a random reboot in a while. From day 1 I could count on 1-2 random rebooted with my Atrix.
Sure enough, my uptime is 280hrs+, which is in line with when I took the OTA update. My wife's phone appears to be the same, and it was rebooting at a similar rate to mine before the update.
Both are rooted/non market enabled but not modded.
How's your stability been on 4.1.83?

I had one strange reboot this morning, my phone had been lagging up a lot, along with the screen not turning on when I pressed the sleep button.
I look down a minute later and I see the Motorola logo. But afterwards it seemed just dandy.
Random reboots
I just bought this phone Friday at 7:45pm. It was working fine when I got home Friday night after purchasing it. I hooked it up to my pc and got the needed updates to 4.1.57.MB860.ATT.en.US. Saturday morning I installed one game bejeweled and advance task manager before heading out to work.
I got back home around 1:30pm and started setting up my contacts on the phone. Around 6:00pm I left the phone plugged into my pc and heard the phone rebooting from the other room. At first I thought maybe there was an update and that's why it was rebooting.
Two hours later it did the same thing again with no warning about a reboot when I was manually adding new contacts. I notice there was another update available to version 4.1.83 which I now have installed on the phone and it's still rebooting on its own.
I also noticed that my battery was right at 60% and while plugged up to my pc it was only recharging 10% every hour on the hour not sure if that's normal for this phone.
(Two hours later battery power at 90% with a solid green power light visible but taking forever to reach 100%)
Also right after the 4.1.83 update the phone would reboot and then the battery light on the phone would just randomly flash red with the motorola logo sitting on the screen. I had to pop the battery out, waited for about 30's before putting the battery back in and powering it back up and it still sat on the logo screen with the red flashing light.
(The battery is now at 100% but 3mins after unplugging it from the pc it displays 90% again all I've did is watch it reboot on its own.)
I removed the battery again but waited for about 5mins before powering it up and this time it actually booted up like normal and about 30mins later another reboot.
I also noticed that as soon as I finish watching a video with youtube the phone reboots a few seconds after the screen goes to sleep. Now as I am writing this comment I decided to uninstall that advance task manager program and do a reboot. The phone is at 80% and after I watch about three videos with youtube the phone didn't reboot.
I have no idea what's up with this phone and I really like it alot except for this mysterious rebooting not to mention other people experiencing random reboots. I read online where a lot of people where saying it was due to a bad battery and that they got a new battery from Att and the problem went away.
I am really thinking about turning this one in for a new replacement but some people are saying even after doing that they still kept having the problems.
Could this really be something wrong with the updates that is causing issues with the phone or is it just a bunch of bad batteries?
Battery?
Back again, in the post I made earlier I mentioned how the phone wouldn't randomly reboot when the battery was around 80% well the battery charged to 90% and the random rebooting has started up again and it has rebooted 3 times back to back now that it is at 90%.......I think I am going back to the Att store when they open today and try getting a new battery............

If I were you I would get a replacement phone. I did have one random reboot since updating to 4.1.83 and that was the first ever I've noticed with my phone. Otherwise I haven't noticed any issues. As for charging via a pc I did hear that was slow. I charge via power outlet or using a car adapter and both are fairly quick. Good luck.
Battery?
I decided to do a factory reset on the phone first and the funny thing is after the reset, the phone still showed that it had the latest update installed even though I still had to go through the setup process just like when I first purchased the phone. So far it appears to be working and hasn't rebooted on me yet. No rebooting after playing Youtube videos either. The only small pet peeve I have at the moment is the Facebook & MySpace contact photos will not show up for some unknown reason in the contacts sections, they're just empty picture frames. The contact photos that do show up are the ones from my google gmail account and I manually added those online myself so those automatically transfer when my phone syncs with the gmail account.
And the MySpace widget doesn't show a photo as well but the info in the widget is current. That's way better than experiencing random rebooting when you really need your phone the most.

This is normal. A FR cleans all of the user data reseting it back to a "clean" version of the flashed rom.
I can say that I have also not had any reboots since .83 but it is also the first time i have loaded gingerblur.

[Q] S5 Dead Overnight

I have the SM-G901F version, 805 processor.
I finished charging my device last night at 100% and took it off before sleep, all was well. I woke up this morning, and it was dead at 0%.
Something similar has happened twice in the past and that is the screen refusing to turn on, and when it does it jitters a lot and says a certain app has crashed. The first time THIS happened, it said nova launcher crashed. The second time, same day, I locked the device while still in whatsapp and the same thing above happened but this time it said WhatsApp crashed, this leads me to believe it's not Nova launcher causing it but you never know. During the time of these crashes when the screen was off, I had rapid battery drain.
This is why I think overnight something like this happened, and since I didn't try and wake it up like the other two times the battery continued to drain. However, I have attached an image of the battery info suggesting that the phone app caused this.
*I close all apps before sleeping, all the time.
*Data off, blocking mode on.
*Never leave it on charge over night
*UK device, only had it for about 1 month.
...
android doesn't need apps to be closed manually.
sometimes its better to backup all your data and start fresh mate. that's will isolate the problem a bit more.

[Q] Phone won't wake up/black screen

Hey guys, been having an issue on my N4 since I installed lollipop. It seems that leaving bluetooth turned on is causing my phone to have the SOD or not wake up. Notification light will still flash, but screen won't turn on. The only thing to do is hold the power button down to force a reboot. I have seen this happen on my wife's N4 also so its not just my phone. I have left bluetooth off and the phone has stayed on for over a week. But after turing BT back on and using a bluetooth device (handsfree earpiece) with in a few hours this issue crops up.
I even restored my phone completely back to stock and am still seeing this issue. You can check the battery stats after the reboot and it shows it kills the cell modem, but the only thing that stays powered is the wifi, but the battery part of the screen shows like the phone is off.
I haven't tried leaving bluetooth on and having wifi off, but something is screwing it up. I was hoping the update to 5.0.1 would fix this since we got an updated kernel, but its still happening.
anyone else seeing this? surely I can't be the only one seeing it on my 2 phones.....
In fact I just experienced this this morning. The only difference is my phone appears to have locked up during the night and my alarm never went off which caused me to be late for work. I also don't have my Bluetooth on, only WiFi.

Deep Sleep issues?

My phone has not been able to get into deep sleep. For the last few days that I've checked GSam, it's always been at 0s of deep sleep. Just checked right now and after 21 hours, my phone has gotten 10s of deep sleep. I've done a search and looked through many pages of posts on some of the various battery discussion threads but I haven't been able to find anything. Does anyone have a possible remedy for this or explanation of why it's happening? Is anyone else having trouble going into deep sleep?
Mines is the same, I assume it's because I charge my phone every night, which is really the only time my phone would sit still inactive long enough to actually enter doze.
I might of fixed my draining battery issue so maybe you guys can try it out too. My issue was my phone would not go to deep sleep and would stay awake even when the phones display was off so something was keeping it up. I tried all the different methods out there including the package disabler and doing the hard reset with the cache reset. I was browsing the developer options in the settings screen and looked at my running services. I noticed that my contacts and a. Program called com.qualcomm.location had a message next to them saying restarting while all the other programs just had a countdown of how long they were running. So I clicked on each and pressed stop and I also re-downloaded the package disabler and disabled the com.qualcomm.location. after all that I synced my contacts again and just did a simple reboot and after that my phone was able to deep sleep. Now my battery is not draining like it did. So in my case those 2 apps had an issue and kept trying to reset itself so the phone was never able to sleep. I would recommend looking at your running services in the developer options. go into the running services and see if anything is trying to restart itself over and over again
So I did finally achieve deep sleep. I tried a few things from the temporary battery fix thread and I wasn't able to pin point one thing which worked, THEN, I restarted my phone and it wouldn't go into deep sleep again. I tried wiping the cache and restarted and suddenly it's going into deep sleep again....
I'll keep an eye on it and will update if anything interesting happens.
I finally charged my phone prior to going to sleep and it finally did dose last night, the phone has to be stationary to enter deep sleep

Doze and deep sleep seem to be too different things. My phone will sometimes doze without going into deep sleep. What's really weird is that sometimes my phone will randomly stop going into deep sleep and a clearing of the system cache immediately fixes this. There have been at least two times I can confirm I *only* did a cache wipe and the issue was remedied.
Does anyone have any idea why this is happening and why clearing the cache helps?
Anyone figure this out? Also is everyone on stock? Im rooted and on superman rom, this is happening to me every day now after i charge it over night. I have to restart my phone to fix.

same for me on Galaxy s7 flat exynos sm-930f, no root, stock rom
very annoying
if you find a solution suitable for me (without root) please let me know
same here to me stock exynos s7 when plug off the charger in the morning have to restart the phone otherwise battery dies half day
I figured out that for my phone it defenitly is somehow connected to the fast-charging function.
When using the fast-charger the phone doesn't go into deepsleep anymore.
It happens as soon as the phone touches the fast-charger, it doesn't even need to fully charge for this to occur.
When charging with everything else, incl. Qi nothing happens, but as I said, after the fast-charger was connected - no deepsleep.
At least that's what I observed, no guarantee that this affects everybody.

It is the same issue that has been discussed for a while in "high android system battery drain" thread. Read up last few pages.
