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.

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.

Earlier today, a few apps on my Nexus 7 have just started closing within one or two seconds of opening them.
Google Search Bar, Facebook and Catch Note all close within a couple of seconds after opening them. I have used them fairly frequently for the last few weeks with no problems. Other apps, such as Twitter, Chrome and some games all work fine.
I have turned my device on and off a couple of times, but the problem still persists. Any ideas?
The problem is still occurring for me.
Gmail, Calendar etc... all also closing within a second or two of opening. Is this a common problem?
Is your N7 all stock or do you have a custom rom?...custom kernel?
You really need to provide some information in order to get help.
I haven't seen it in the OP so: Reinstall them

I haven't rooted my Nexus, or anything like that, it's all stock.
I just uninstalled Facebook, then downloaded it again. It seems to be working. Other apps still have the same problem. I assume that I have to do the same for all other apps - but is that even possible for apps such as Gmail, Calendar and the Search Bar?
Uninstalling and re-downloading hasn't worked as I had hoped.
It seems to have worked for Facebook. But I did the same for Catch Notes, and although it worked for a minute or so when setting it up, after creating a test note, it force-closed, I opened the app up again, and the old problem of closing within 2 seconds happened.
Other apps such as Gmail, I uninstalled, 'updated' again, and nothing changed, still closes immediately. There is no error message, it just returns to the home screen.
I thought that Task Killer might have been a problem, but I uninstalled that, restarted the Nexus, and the problem persists. Actually, when I turned off my Nexus, and tried to turn it back on, it was stuck on the 'coloured X' screen for a few minutes, I had to hold the power button down, and turn it on again. I'm starting to worry about my Nexus now.
Update:
A couple of other odd ones.
Google Drive doesn't even open. When clicking on the icon, the normal shading effect happens, but nothing else, no window even for a second.
Google Calendar opens, and just has a white screen, as if it is ready to load the calendar, but nothing loads. It doesn't close, just remains on the white screen, which can't be backed out of without pressing the home button.
Have you tried doing a cold-boot on the device? Maybe another app running in the background is causing conflicts. Where there any recent apps that you've downloaded?

I have just followed the instructions for a 'cold-boot' and now my Nexus can't get beyond the 'X' screen...
I have held the power button down a number of times, and tried turning it on again - but the 'X' continues to be displayed for over 20 minutes.
Just managed to turn my device on - but the problem still exists.
I didn't download any new apps that seem to have caused this problem. Though I think an app might have force closed and the Nexus displayed an error message such as "android/Google system stopped working" (probably different) and my home screen went blank for a while. Everything reappeared though after a short while. It could have stemmed from that.
Sorry about another bump, but i'm wondering if anybody has any more ideas before I go for a factory reset?
Edit: Actually, I think that I have found the cause of the problem. I just opened a game (Let's Golf 3) that I was playing before the problem started and after a few seconds, a message popped up saying "Unfortunately, Launcher has stopped". When I press OK, it returns after a few seconds.
I pressed the sleep button, and my Nexus turned off. Now trying to turn it on again, having some problems getting past the 'X' screen again. If I finally get in, should I uninstall the game? Any other solutions to this problem?
If your N7 can boot up, go the isolate & identify routines - disable/uninstall or freeze the golf game - do a normal shutdown/restart.
If normal functionality is back, you've just found the source. Not a gamer myself except for Angry Birds ... , but from the Play Store description, it access & make changes to system & protocol, etc. as you should contact/email golf's tech support for resolution. Otherwise, take a look of any background running apps or widgets, newly added or updated.

Thanks for the help.
I couldn't get my N7 to boot up, so I finally gave in and did a hard reset (by holding power + volume down, Recovery Mode, then wipe data etc...) but my N7 still won't boot up
I have wiped it twice, and rebooted it, yet it is constantly stuck on the 'X' screen. What on earth can I do?

You will need to download the factory image, unlock your bootloader, and flash it. There is a guide on this forum, it might be stickied.

I was hoping there was going to be a resolution to this other than a "flash to stock" suggestion... My Nexus started doing this exact same thing this past Sunday when it ran out of power completely and needed to be recharged. After it powered back up from charging the following apps quit working altogether or just started quitting once it appears they try to access data: Netflix, Currents, Zillow, Gmail, HBO Go, Press (though Google RSS Reader works), NVision, TegraZone and a couple others. I have done the reboot thing as well and almost had this thing brick again (stuck at X), but I managed to clear the data cache from the fastboot menu and it started up again. I'm now at the point where I'm troubleshooting individual apps but the clear data/cache, uninstall - reinstall process isn't working for any of the broken apps. This is now the 4th time I will be facing a 'flash to stock' situation as it appears that I've had every problem that leads to this 'fix'. I'll try a couple more things (mostly deleting and clearing everything) but I'm really frustrated with how many times I've had to flash this damn thing. sigh.
Guys , i have been facing a strange issue on my Note 3 (SM-N900 running stock JB 4.3 , not rooted) .....Whenever an application acts funny i.e whenever there is an Force Close of an app & thereafter when i switch off my device & restart the phone keeps on rebooting till i open the back cover & remove the battery & reinsert it !!!
Is this normal ?? I installed my favorite LWP "Ditalix" (purchased premium stuff through in-app purchase to make it ad-free)....I was changing a few settings in that LWP & i experienced a black-screen issue (something must have gone wrong) , i had to switch off my device & on restarting , the phone went crazy & kept on rebooting till i removed the battery & reinserted !!!
Today i reset my device to factory settings , formatted my External SD Card (someone told me that it could be one of the reasons for reboot)...I have purchased "Beautiful Widgets Pro" ( very popular set of widgets available on play store ) & i installed it & i was downloading a few clock & weather themes via in-app facility & i experienced FC a couple of times , thereafter i again shut down & restarted my device & this time the device started after 1 extra reboot , i rechecked & the same thing happened again ....I uninstalled "beautiful widgets pro" & again repeated the process & this time it started on single reboot .....One more odd thing happened this time , usually on restarting the device the "multi-tray button" appears on the left side of the device but now it doesn't , i have to long-press back-button to make it appear......
Is everything ok with my device ???

[Q] Reboot cycle after restart help
Sent from my SAMSUNG-SGH-I317
Was just about to post a thread similar... Besides the random reboots and bootloops..... too many apps FC. I never had a phone where so many of my apps FC. Nova Launcher force closes about 2-3 times a day. Alot of apps instantly FC upon opening.
Since I got it, I have had about 5 random freezing and complete restarts. Once when YouTube was playing, the audio froze and produced a horrible buzzing sound then restarted.
I did a factory reset and it has happened twice since. I'm wondering if I have a faulty SD card...
Anyone else?
I got mine on Monday and so far no problems

Do you have an SD card in yours?
That happens on my daughters Nexus 10 tablet, it definitely is YouTube and the high definition videos that cause that, it's unfortunate to hear that is happening on this phone.
No issues here or with YouTube. Yes i have sdcard.
yea! same here. i have random restarts!!! i thought it's just me. and I have SD card inserted.
this was me playing games... Fate/Grand Order in particular... i don't have sound on, so I don't know if what's happening...
the phone just goes black, and then the samsung boot logo starts.
I have no issues with g935t w/ sd card
my restart doesn't happen often, maybe like once every 2 day... and almost always playing games or was just playing games... i wonder what's wrong X_X
Only had one freeze and that was when it first booted and was restoring apps. I was uninstalling apps at the same time it was installing them and it froze for like 10 seconds. Other than that no issues.

Mine freezes then reboots every 10 minutes and gets super hot.No memory card inserted. Factory reset 3 times and disabled apps but doesn't make a difference.

No freezing so far. I've had my S7 Edge since Tuesday and I'm using my same SD card that was in my S5. I've watched YouTube several times as well as played several games ranging from Mobile Strike to GTA Vice City.
same here. I got my s7 edge on Wed eve. setup everything. No Issues then. next day morning on the way to work, it got restarted for the first time. While walking to Office, it restated couple of times. no specific pattern to it. If I try to do anything, it gets freeze and after few seconds, it restarts.
Couldn't check if it got restarted while at work. but again in the evening, I made a samsung Pay at a store and while driving back, it got restarted. Then at another store, it keeps on restarting after each reboot. Device gets hot as well. really hot.
Tried factory resetting, but immediately after I log back in, it restarted, at the same place.
I turned on Airplane mode and then device cooled off, and it ddnt restart after that. After 15 min or so, turned off Airplane mode, and device ddnt restart yet when Iam writing this now, almost 3 hours later.
Starnge thing is, it never gets restarted at home. it always happens when Iam outside. Something to do with the network? Im on ATT.
another issue, even for small tasks like browsing websites, device gets hot. Hot enough that you will notice.
Not good sammy. Iam a fan of you since 2011 and none of galaxy had issues atleast from day 1.
Iam gona wait a day more, if it still restarts, I dnt want them damn warranty/replacement. Iam gona get iPhone6. I dnt like ios, but atleast it wont die on me like this.
Woah!!! as iam writing this, it got restarted now. WTF! Guys pls stay away from s7 pls!
I had one really random reboot. Next the frone has issues with enabling fingerpring authentication in Play. It stops responding and anter about 15 seconds reboots.
Mine rebooted once during installing all my apps first use

Got one rebbot too.
While installing an app from PlayStore. During paiement, freeze and reboot.
While I tryed again after reboot, freeze again but it passed.
Got an other freeze on chrome an other day.
SD card inside (64gb) from my old phone. Never got reboot on it.
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.

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
