Constant Phone/Touchwiz reboots - help if you can

Hello everyone, I've got an interesting problem that I want the experts here at XDA to help me troubleshoot. Feel free to ask questions as I know there's probably a million variables at this point with stuff installed, uninstalled, gps, root, task killers, etc.
alrighty with that said, I did the e-wrecked gps fix (changing the operation mode and server location+port). That seems to work great in terms of time to lock on my position as well as improved accuracy. Over the next couple of days I noticed some really choppy and lengthy phone start ups after the fix.
Eventually it got to (and currently is at) a point where it kept rebooting the phone, or at least touchwiz. It would load up, scan media, search for the network, do all the start up stuff, then lock up, and turn the screen off. Hitting the lock button/power button does nothing while it resets itself. Then it resets to the lock screen, the screen lights up and it goes into "searching" for the tmo network while doing the storage preparations, and other boot up stuff. It does not restart from cold (with the vibrant, tmo, and galaxy animations, only the lock screen and OS boot process)
Anyone else got any funky restarts going on, for whatever reason? I basically want to start seeing what would trigger this behavior. I started uninstalling stuff one by one trying to figure out why its doing that but sometimes it boots up fine, sometimes it boots but doesn't ever find tmo's network, and sometimes it just does the above.
Observations:
1. It will always boot up fine if the SIM card is out.
2. The last time it did it was today while I was at work, listening to music while the phone was charging. Im noticing that the phone gets pretty hot while charging and really hot if you're using while its charging (getting apps, surfing the web, playing games, etc)
So any thoughts from the tech gurus here? anyone have similar behavior in the past on other phones? is the heat affecting the sim card negatively? I can (and have) put my simcard back in my treo 680 backup phone with no issues whatsoever.

New observation, it consistently does the reset process as soon as the "Adjust Time and Date" as it registers/syncs with the network.
UPDATE: so, i did some research, ended up at the setCPU thread and saw that when set to OnDemand some people's phones experienced similar tendencies. Problem is, mine was already set to auto-detect and "Conservative". I un-checked start at boot, and tried again. Same problem. I uninstalled setCPU completely and my phone appears to be back to normal.
I'll update again if anything changes.

so one of the things that i removed during my troubleshooting was my corporate exchange account. When i added it back. it did its initial sync fine and gave me my calendar and contacts. I then rebooted and the problem came back.
I removed the account and rebooted. it went through two cycles of the restarts and on the third one, it worked. I left it alone after that.
I then was showing my friend some things (browser differences) and had 3 browsers open. It froze as i went to close Dolphin HD. Rebooted and now its back to the cycle.

Mine did this also. Installed several apps, woke up to find a slow phone. Resets galore. A quick reset to defaults and app restore fixed it, sans setcpu of course.

my phone resets itself also as described above, but not really doing anything in particular. i dont have a whole lot of apps installed. i even was using google maps the other day and after it started up the screen went black and the device was unresponsive until the screen came back and it said searching and the media scanner was running.

well first off thanks for responding lol. i thought i was by myself out here.
secondly, i found that if i leave it alone and let it go through its cycle, it does eventually boot up ok (this is recently, before, it was endless). i havent restarted my phone (im afraid to lol) since it did it on its own yesterday (showing my friend the browsers).
since yesterday, i've used it for navigation (motonav), serveral installs, downloaded podcasts, rss feeds, etc and its been ok (even while charging and wifi on). again, havent actually restarted it since yesterday because its actually functioning for once.
Lastly, i unchecked the auto update time and date from network in the settings just to see if that makes a difference because based on previous expereience that is the point where it freezes and resets. Thanks for chiming in and let me know if there's any other advice you have

I'd suggest a reset as mentioned above.

Been checking out this site for awhile but this is my first time posting, today my phone started to have this problem and it just bootloops touchwiz if i have a simcard in the phone.
It works fine without a simcard but my problem is it will not let me turn of auto update of time and date, i have tried disabling this setting and it just enables itself again. I have also noticed that if I started messing around with time and date settings even without a sim touchwiz reloads once. I guess im gonna give a reset a go.

sorry, noob question (i came from winmo and a touch pro 2), what does "a quick reset to defaults" mean? is that like a factory wipe i.e. phone will be brand new again, gotta root again and reinstall everything, change settings, etc?

Root will stick but settings and apps/app data will be gone. It briefs you on what is and isn't lost when you do a factory reset.

Smae problem, its setcpu!
SetCPU with any settings will do this.
It needs an update, the auto detect some how loses and
will set the cpu to 19mhz max and min.
This is too slow to process. I rebooted and pressed settings and uninstalled it
while I could. Seems to behave once out of touchwiz.

For me it was another app not setcpu I never used it. After i did a reset i restored all my apps with titanium backup and once i restarted my phone it looped again. So i did another restore and left off all the apps that i installed right before the problem started and so far i think for me at least one of these caused it
Google maps update
google translate
the extra language pack for translate
barnacle wifi tether
hero of sparta
these are apps that I installed right before the problem happened and without these my phone works fine I am going to see if i can find that one that caused my problem.

It's not the maps update because my phone works fine with it.

It was hero of sparta a gameloft game from there web market funny thing is its suppose to work on the vibrant while dungeon hunter which works fine would only give nexus as a check out option. Anyway im going to try to get a refund tomorrow.

I get the same touchwiz reboot but for me it has only ever happened while using google maps. I do not use set cpu, but I have applied the gps fix. It is more than a little annoying. I have done a system wipe but the problem persists.

yes, if you have setcpu, uninstall it - its buggy with the galaxys
- sometimes you can't wake your phone (if you set a screen off profile), forcing you to do a battery pull
- constant launcher restarts

and this is why i started the thread, to make sure i wasnt all alone. i have everything you have installed as well, but it was doing it before i picked up hero of sparta (and nova, and asphalt 5, man those guys make some good phone game lol).
anyways i just installed barnacle wifi tether yesterday so thats not it either (at least for me). That leaves the google stuff, out of the apps in your list, all of which were installed when i first got the problem, and are still on there after I've removed setCPU

ok so, contacts, text messages, etc stay? Meaning if i do a factory reset, root stays, and all app stuff can be taken care of by, say, AppBrain since it has a running list of everything installed and knows where to get it to install it again? I apprecicate the advice, but this would still be a last resort sort of thing. my phone has worked fine for the past few days but I also havent restarted it yet either

just a quick update, my phone still does this if i reboot my phone (which is never now that i got my 32gb sd card), but for the first time ever hero of sparta caused it to happen while the phone is on. I uninstalled it so we'll see.

[ISSUE] Nexus S having nightly "sign-offs"

Most of us here love our Nexus S phones. We love Android 2.3's speed and the neat little TV effect when we lock our screens. Since Friday morning, (Feb. 11th) my Nexus S seems to be having another TV effect: nightly "sign offs."
It does not matter if I was charging the phone or not, the phone would just stop working. The strip of touch buttons along the bottom of the phone could be lit or unlit, but the screen would just turn off and no button presses would wake the phone. If I plugged it in to a computer, you could hear a "device connect" noise and see the Android hard drive appear under the Device Manager in Windows.
All of this means that the Nexus S was powered, but not responding. It would not reboot itself, and yes, I have experienced the reboot issue. This seems to be a separate issue. This only seems to happen after midnight.
The only solution is to pull out the battery and reboot it manually.
If my Nexus S is still on when this silent crash occurs overnight, my battery could be completely drained by the time I wake up, making me plug it in AND requiring a battery pull.
Has anyone else had this issue occur? According to the Android Market, I've only updated a few programs recently, one of them being Twitter.
Some Recently Updated Programs: (most recent first)
T-Mobile My Account (to 5.0.15)
Google Authenticator (installed, 0.54)
Google Goggles (to 1.3.1)

When I woke up on Friday, I called Samsung and they did note the issue under my phone number. I will call them again Monday and let them know I'm still having issues.
Any help/suggestions from the XDA community would be appreciated.
Thank you!

Just checked this morning, (Monday) and I had to pop out the battery to turn the phone back on. Before I went to sleep, my battery was at 100%. When I woke up and booted the phone up, it was around 30%. A 70% drop in 8 hours. Time to call Samsung again.
No one else is having this issue?

Sounds like either a defective unit, or messed up software.
Try doing a factory reset and use don't install many apps and see if that resolves for problems for a day or 2.

Well I had a strange issue that I had never seen before... at around midnight last night both my NS and my gf's went into bootloop at the same time, it was freaky. We're both on CM7 but hers is an older build and mine has netarchy's but it's never happened before... pulling the battery and powering back on fixed both phones but it's still very weird.

I have never actually called the manufacturer before about any issues with a device. Do they do anything for you? Or help you in any way?

Samsung suggested that I do a factory reset and then if that does not fix the issue, then I'll have to send the phone into them. The tech I got on Friday was more knowledgeable than the one I got today. I'm going to backup my data and then do a factory reset, making sure not to "pull" my data from Google's servers.
Man, not doing that is going to suck.
I am also using Google Voice for my voicemail. Just wanted to throw that out there in case any running services or something is causing all of this. I'm thinking that the new version of Twitter is causing this, as it's baked into Android now and there was an update recently. Thoughts?

Here's a small update on my issue: it seems to be software-related. My Nexus S crashes during the day as well, requiring a battery pull as described above. Disabling sync does not solve the issue, so it doesn't seem like it's coming from that area. What would you guys suggest my next place to look be?
Thanks!

Well, have been having almost the same issue for the past two days. Go to bed with 57 & 63%. Get up in the morning and the phone is dead. Not sure of the exact time it.passes away, but yeah.
Can't understand why the phone has to drink while I sleep.

Same prob, only intermitant though. Im using rc1 now, with no custom kernel.

I've been having the same issue since the 13th of Feb. At first it would freeze only overnight. Now, since the 14th it freezes while asleep 4-5 times a day, and the only way to get it working is to do a battery pull. I've tried to remove recently installed apps and widgets, but that has made no difference. I really don't want to have to do a factory reset, especially after I've been reading on google forums about other users not noticing a difference after a factory reset. This is getting ridiculous.

Agreed. Mine started to freeze during the day as well, requiring a battery pull. Do you have the new Twitter installed? Do you use Google Voice for voicemail? I'm trying to pull together some common threads. It's definitely software related.
Edit: OK, now this is just stupid. It seems like I'm freezing up every half an hour by now. I pull the phone from my pocket to check on something and I push the power button. The lockscreen shows, but the screen and touch buttons don't respond. Battery pull is the only option.

Yes, I do have the new Twitter installed, and yes, I do use Google Voice.
It seems to be happening more often now for me as well. Sometimes it takes two to three times for it to fully restart and get to the home screen, or the lock screen, and sometimes it will wake and then freeze on my pattern lock which also requires a battery pull.
I've starred a few forums on this same issue on the Google support forums, I hope others do the same to show support for a quick fix.

Last night I had the battery at 90. Switched of Wifi, Data and Sync.
Got up this morning and ... no probs The battery dropped to just 88!
BTW. I have got a stock unrooted phone with no Google Voice or twitter so, could not really be a problem related to that.
I use the app addin timer to run stuff at particular times. Other apps that I downloaded are calcbuddy, barcode scanner (which I think is pointless and going to remove), pure messenger, calwidget, appbrain (again, did not like the new updated one), aTakephone, Flip4Silence, CoPilot, Fast Reboot, Docs to Go, Skype, Remote Desktop, StockIndia, Tunein Radio and Widgetsoid.

Thanks for letting me know the apps you have installed. The only common ones between us are:
Barcode Scanner
Skype
Barcode scanner is actually useful. (QR Codes, etc.) Skype may have something to do with it as it does integrate itself with data sync. Thoughts?
In order for this theory to hold water, your phone must:
Crash and require a battery pull to be responsive
Have Skype installed
Edit: My phone was crashing so much that the "first time/welcome" wizard was coming up. Swype, Facebook and GMail were crashing left and right. Time for another Factory Reset....
Edit 2: The phone has SOMEHOW survived a Factory Reset from the normal phone menu AND the Recovery menu! WHAT?!

My Nexus S is going back to Samsung for repair. *sigh* I wonder what they'll say caused the issues?

Now, today, the phone doesn't get passed the initial "Google" screen. No matter how many times I pull the battery, plug it into a charger or usb port, it does not go past the first google screen. Very disappointing.

Can you get into the bootloader menu? (Volume Up + Power)

Yes, that allowed me to get to the bootloader menu, but I couldn't do a factory reset, it just sat at the screen with the android and an exclamation point inside a triangle. I then did a battery pull, tried a normal restart and got to my home screen.

Glad to hear that you got in. By the way, once you get to the exclamation point screen, you can push Power while holding the Volume Up button to bring up a menu.

Cool, thanks for the help!!

Random reboots/restart...what's the latest on how to fix this?

My stock S7 exhibits random reboot behavior. 1-2x per week. Once in a while it happens 2x in one day. Once it a while it happens at the most inopportune time, like when I'm trying to take a picture of an event. When the reboot occurs usually it boot loops several times (and the phone gets warm while this is happening) and then finally stops. For the first year or so of owning the phone, no reboot problems. I did see the unmounted SD card notification issue that others reported (with a Samsung SD card). A while after the nougat update and after the 1 yr warranty period of course....random reboots. Also after the boot loops stop and I'm able to use my phone again, my Spotify login is lost and I have to re-download my playlists that I had saved locally. This is a real PITA if I'm traveling and not near any wifi connection.
Any ideas?
I've done the following:
- factory reset twice
- removed the SD card, not using it anymore -> I could consistently get the phone to reboot when scrolling through my pics in google photos. I do not get this behavior anymore with the sd card removed
- install a minimal amount of apps
I've read countless search results from Google search results and nothing has solved my problem. I'm past the 1 yr warranty period. I called a local shop and was told the cost of replacing the mainboard pretty high, I'm better off just getting a new phone...which I would like to avoid. Today I disabled the built in weather app to never refresh. I have little hope that this will fix my problem, we'll see.
I don't have any launcher apps. No games. Basic apps like Bank of America, Evernote, Flixster, Spotify, Swiftkey, Todoist, Logitech Harmony, etc. I disabled the built in Amazon app and installed the Amazon app from the google play store.

I have the same problem. Also after almost 1 year I am now getting random reboots. Especially but not exclusively uwhen using google maps. Mine is still under warranry.
Update: did a factory reset via recovery, working fine again.

Overnight while charging, my phone decided to bootloop until the battery died. Woke up to a warm phone that would not power on for about 20 min. I put the phone on a gel ice pack and now it's finally on. Uninstalled and disabled a bunch of apps, always on display, bluetooth etc. Just need this thing to stay alive until I can trade it in for the new Pixel.

Moto X Pure Randomly Reset Itself

Hey all,
Just curious if anyone else has had this issue that I just experienced. I was using my phone like normal when it dropped to 3% or so battery life so I went to go plug it in. After sitting on my nightstand for 1 hour or so I picked it up and went to unlock it, but it was doing the whole "New phone tutorial" thing on the unlock screen which was a little confusing.
That's when I unlocked it and realized that everything was gone. Both of my Google accounts had unsynced themselves with my phone and it looks like my entire cache was reset. All of my text messages, gone, pretty much everything was wiped except for my pictures and other files.
The Google Now launcher is no longer working either - I can't swipe to the left to access the Now cards (This is really the least of my concerns though).
Is there a way to look through logs or something to see what happened? It seriously sounds like there was some sort of catastrophic failure and the phone just nuked itself - but I've never had this happen to any of my previous phones.
This problem mixed in with the phone shutting off randomly at 35% (Was fixed by doing a 'battery calibration' with a guide on here), the touch screen being unresponsive at times preventing me from unlocking the phone, and the white washed out lines issue that never has been fixed makes me really question whether or not I'll consider buying Motorola (Lenovo?) ever again. :|

j5(6) turns off by itself

Hi everyone, if you have this problem of a Samsung galaxy J5(6) turning itself off at any given moment, I think that I can help. I bought this phone in December 2016. Great phone, quite easy to root, and reliable until it started turning itself off in early 2021. At first, I would turn it back on, and it would be o.k. for a while. Then this annoying situation became more and more frequent. I read a lot of tips that could help on the web, like cleaning cache, reset the phone, change the battery, and re-install the rom via twrp, but nothing worked out.
Starting in safe mode did not help either. I uninstalled apps, reinstalled apps, turned my vpn off, nada.
I think a lot when I rest, and once a new idea came up. I installed the app ''BLACK SCREEN'' , ran it, so that the screen would be totally black, and since then (5 days and counting), the phone never went off by itself.
The launcher is still on as well as any apps that were opened, but they are invisible until you reset the screen to its normal state. The phone still can receive calls an turn on the screen when it rings. The battery raised its available time remaining by more than 50%. Amazing. It really worked for me, if you have this problem of your J5(6) turning off at any moment by itself, give it a try.
Thanks
