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.
Had my Verizon 7.7 i815 since 4-30 and love it except for one issue - it reboots at least
once a day usually when its connected to the charger.
I need help figuring out if this is a hardware issue so I can just exchange it or if is
software/other issue that I can resolve myself.
When it reboots it goes to a black screen with a single white dot in the center.
It is playing the reboot jingle when this happens.
Sometimes it will bootloop and I have to press the power button for a few seconds to
reset the tab.
Honeybar is installed and AdwLauncherEx is the launcher.
I have tried booting to stock recovery and clearing the cache and did a factory reset - didnt help.
The tab is rooted.
I also removed the Sandisk 16gb microsdhc card after a reboot at 5 am because I had read about users who were having issues with their tabs until removing or switching out their sd cards. The tab went without rebooting after that for 19 hours until I installed
Hidebar. After installing hidebar the tab rebooted twice within a minute so these two instances may be because of that app. I uninstalled it after that and went back to
Honeybar.
I have only experiened a white dot reboot when trying to swap the phone.apk (it was a never ending reboot). I otherwise haven't had it reboot on me. I don't use any bar hiding apps.

Just to be clear my tab was having the reboot issue long before
I installed hidebar - I only installed hidebar tonight and have
owned the tab for a week.
I am however able to cause the reboot consistently with hidebar.
Well the reboots started again after almost an entire weekend reboot free.
Going to exchange it at Verizon for another 7.7 tonight.
Good luck! hopefully the new one is error free.
I've had the same issue with mine, also a vz 7.7.
It was happening in a loop the other day and I managed to capture a video of the entire sequence.
I don't actually think this is a reboot but instead seems to be more of a screen and radio lockup.
I get the little dot in the middle of the screen. After 20 seconds or so the tab goes back to the lock screen. Once unlocked it has to re-connect to either Verizon or Wifi.
I tried disabling the wifi and 3g/4g networks and this seemed to improve the situation but yesterday I was able to get it to do the same thing with the radio's disabled so probably not chip related.
I'm still within my return window I think. Seriously considering returning the thing mainly due to this problem and the lack of ICS.
Had a GT8.9 previously and even though the screen isn't quite as nice it was a pretty great tab and cost half as much *and* can access the awesome AOKP ICS rom.
--tr
Yep, development for this tab is non-existent at the moment.
I'm stickin' it out tho and hoping for CM9 sooner or later.
Same here. I can't find a pattern to what triggers it. The first time i was installing a bunch of apps from my computer via Google Play (not tethered to PC). I pull my microsd and sim and it continues for several cycles. Did a bunch of the stuff you did also w/ clearing the cache and actually the first time i couldn't get it out of the loop (it would actually get into the desktop where it looks like it would be ok, then suddenly screen w/ the white dot in the middle and looping again). Never got close to depleting the built-in storage, so that's not the factor.
Sometimes I can get it to stop by turning it off by holding power down and turning it back on again. It doesn't happen a lot, but it's freakin annoying when it starts.
I don't have honeybar, but am running ADW.
Wow, good to know others who are going through the same issue...I thought I was the only one! I still have the reboot loop issue even after performing a hard reset. For me, the reboot loop only occurs when I'm on a cellular connection. If I'm on wifi or on airplane mode, it doesn't happen. I'm well past the exchange/return policy so this is extremely irritating.
Personally, the most frustrating thing is that my tab will be fully charged at the start of my day, then in my bag for the morning while I'm at work and then, when I take it out to use it, the battery is completely drained because of the reboot loop!!!
I'm hoping an update (ICS?) will fix the issue but I'm not holding my breath for it...
Same issue here. I am rooted, and originally thought the reboot was from Gesture Control app (awesome app!) when hiding navi bar. But after reading this thread, I'm not so sure.
I've only had the reboot loop once, here is my setup when it happened....
-had just unplugged from charger after full charge
-Mobile data was off, Wifi was set to sleep....never when plugged in..
-The device kept rebooting, so I powered off, went into recovery, wiped cache. I also turned off Gesture Control app functions (not sure if this was necessary however). This seemed to stop the reboot loop.
Would be nice if we could keep gathering info on the conditions that cause this, and potentially find a solution. It sucks having a dead tablet because of this issue.
My 7.7 does the same thing. I don't use the tab constantly, but I do notice the reboot on a fairly regular basis. Same symptoms as everyone above, except for me it doesn't go into a loop, it just reboots once with the white dot and then comes back fairly quickly, so not really a full reboot. I don't see the Verizon & Samsung splash screens, just the white dot then the login screen.
Mine is not rooted, has the stock ROM, and does not have any UI enhancing apps or mods. It's pretty much stock other than having applications installed, and nothing that really runs in the background because I have Advanced Task Killer kill auto kill every 30 minutes.
Not that big of an issue for me right now, but would definitely like to see it resolved.
gawd! It doesn't happen a lot, but when it does it's friggin annoying. Yes, it's the white dot and doesn't show the full bootup splash, kinda just goes to the desktop again seems ok for a minute and then boom- black screen w/ dot in the middle and it starts over again.
This last bout was pretty bad and it didn't respond to shutting it completely down by holding the power button and letting it boot again, which has sometimes fixed this in the past when it's looping like this.
Can't tell what is causing it, at first i thought maybe a live wallpaper, the 64GB sandisk microsd card, or a faulty sim (sometimes my tablet says SIM not inserted, even if it is). I tried changing all of those but it still happens. I haven't found a pattern of usage or other type of trigger to make it do this though.
I've only ever experienced this when I tried adding in the mms and dialer app from the GSM 7.7. Otherwise my tab has been rock solid.

Hi guys just got my s3 couple of hours ago white 16gb for sprint. I tried searching for the issue I am having and no results, so I am posting here. I did the initial android setup and everything was running fine for first 15 min and then phone keeps freezing and restarts, I did many battery pulls and same thing. It would work for min or 2 and freezes and reboots. Then I put the phone on charge and used it for several minutes and no crash.
So I unplugged the phone when the battery was at 52% after charging for more then 45 min, and same reboot issue is back. So I was wondering if anyone else having this issue.
Thanks for all your help in advance.
if you didnt flash things, which i dont even know what you would flash and how at this point, i would say its broken, and you should go get an exchange. Hopefully youre the only one with the issue, ever.
i guess you could try a factory reset, which i would assume you can do from recovery, to which you would maybe get to by powering off, and holing volume up and power(once again, just an assumption).
p.s. i am impatiently waiting untill best buy gets 32gb version in stock so i can trade in this lte evo pos.
i did many factory resets and battery pulls and same issue. so i got tired and called in for exchange, they are sold out right now but will send one out as soon it comes back in stock.
Did you do a hard reset from recovery?
Sent from my SPH-L710 using XDA
any particular app installed that might be causing this? :crying:
Yes I Reset it from recovery and did factory reset 4 to 6 times, No apps installed. As soon as i start navigating through menus it freezes and then reboots. Sometimes it also freezes at sprint logo while restarting, i have owned 200+ phones never had a single android phone with this kind of Issue.

Do you have a sd card installed? If its from a older phone or s2 it might be the problem too. Back up everything in format the card then see what happens....
Thanks for all your help guys !
I fixed the issue by wiping cache partition and factory reset. Before all I did was factory reset but didn't do wipe.
No crash so far

The Device I Speak Of Is A Samsung Galaxy Tab 4 8.0 AT&T (SM-T337A) As You Can Guess By Reading The Title, It Restarts After A Few Minutes. The Exact Time Varies, Was The Device Just Turned On? Has It Been On? It Happened Because I TRIED To Root, I AM NOT Rooted Still, Which Only Made Me Even More Fustrated. But, It's Happened Before, But I Fixed It By Deleting Kinguser From The File System, But The Damage Was Done. It, Unfortunately, Still Ran Slow Afterwards, But Got Better Over Time, But I Digress, I Thought That Since I Wasn't Using Kingroot It Wouldn't Happen Again, I Was Dead Wrong. Now It Runs Slow And Restarts After A Few Minutes While Using It. When I Try To Open Some Apps (Mainly Games) It Closes Before It Even Loads Fully. Another Thing I Noticed, I Turned On 'Show CPU Usage' And In The Area Where The Usage Data Is It Shows "sh" In Green. A Lot Of Them Too. I Think It's Part Of The Problem. Well, That's All For Now. Any New Info I Get I Will Post Here. I Hope Somebody Can Help.
Hello, so i've had this Note 4 for about 2 years, i had no problems with it thus far until recently ( 3 hours ago actually) i was just texting and browsing Instagram and out of no where the screen froze, it became unresponsive and the screen went black and started constantly vibrating so i quickly pulled the battery out and put it back in again, tried to start it again and it got stuck on the Samsung logo, i went for recovery mode and tried to look up latest cashe log and it froze right there too and restarted, pulled battery out and in again, tried to get into Recovery mode for a second time and a dm-verity verification failed error on the lower left corner popped up, i selected "Restart phone" and it got stuck on the Samsung logo again, battery in-out, tried to get into Recovery mode for a third time to do a factory reset but this time it got stuck whilst trying to boot onto recovery, and i had to out-in battery again, tried several times to get into recovery and it didn't work, i just gave up and started searching, then after 14 minutes i decide to give it another try and it normally booted up! i inserted in my PIN and browsed the apps for about 2mins but it froze, again, and the whole cycle kept repeating i let it cool down for 15mins and it boots up normally but freezes again after a few minutes of usage, i noticed that it insanely overheats before freezing (especially right above the SIM card area) and the four CPU cores are showing 2469MHz and on 100% (But that's also the case when the phone just boots up right?), Now i basically can't access recovery mode and i'm stuck with a Freeze-Reboot looped and i'm left with no other option but a full Stock ROM flash, the thing is i can't even get into recovery to do a full wipe before flashing in the ROM, can i just flash in again a TWRP recovery? and is there any way to fix this without having to do a full Stock ROM flash (i Tried the wake lock app it didn't work) and i'm on Android 5.0.1, this has JUST happened today and never before. i'm hoping this isn't a hardware issue.
UPDATE: i have just noticed something rather interesting, the phone immediately freezes and goes nuts with the reboots and failed recovery modes instantly after i connect it to a wifi network, and exactly when it's attempting to "send report", a sending report sign shows up in the notification bar and it immediately screws up the phone until i do another Factory reset, i just did another one without connecting to a wifi network and i've already gone 40mins with it without any issues but perhaps it's just because it's not on heavy usage?
Sounds like you have the eMMC issue.
You can try and reflash with Odin. Get the right version from Sammobile.
Do yu get to download mode in any of the scenarios you describe?
Try WakeLock again and select the level to 4
Having the same issue
I'm having the same issue and don't have any idea how to help, just hoping someone out there knows...:crying:

If you have the Snapdragon version - it's highly possible to have the emmc problem. Which is a bummer and the phone is like dead.
Unless you can buy another 910C motherboard and swap it.
Sorry.
What is short name for emmc?

Just been having a very similar problem. I posted this elsewhere, but it may be helpful:
"My issue was that I needed to recover data, docs, photos, phone numbers etc. When boot looping the note 4 got very hot . In particular around and to the left of the camera (looking at the rear). Thinking it could possibly be the dreaded eMMC problem which also manifests itself by creating heat, I thought cooling the device might help. I placed the Note on a cooler box freezing block and voilà! No boot loop. I was able to remove all, but necessary apps and do a full copy to my PC. Storage was reduced from around 90% to 50% and memory 80% to 60%. It's now been stable for 12 hours, but the jury is still out. Next will be full reset with he latest available firmware 6.0.1 as mine was still on 5.1.1."
Also now downloaded a eMMC bug check that says my eMMC chip is 'sane'. Guess we'll see
