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.

I've just installed the 4.4.2 update on my Advent-branded Tegra Note and the first boot was painfully slow. The "Optimizing Apps" stage of the boot took more than an hour for 161 apps and when the boot was complete the device was lagging to a ridiculous degree. Swiping left or right on the home screen resulted in a jittery page change after maybe 6 or 7 seconds. I eventually had to force a shutdown. Subsequent boots have started OK but with periodic lag for 20-30 seconds at a time. Has anyone else had issues like this?

Oh, yeah. Got frustrated enough that I rooted it and downgraded back to 4.3... That said, try going into recovery (if you're not rooted) and clear the cache from there to see if that helps.

I have seen this randomly, not on the first reboot of Kitkat for me, which worked fine. But just randomly on reboots after the update to 4.4.2. The slowness starts at the initial boot screen because the animated splash screen with the green swirling around the Nvidia logo is super sluggish and slow-mo, almost like the tablet is running on one core or something. If this occurs, I normally hold in the power button to force a hard reboot, then its fine again. Done it maybe a handful of times, but I don't restart my tablet that often. Only started happening after the 4.4 update tho.
workaround

This is not a solution, but instead a workaround that seems to work.
a) Firstly you need to turn on the 'developers options' in the settings menu.
Go into 'Settings' > 'About tablet' then tap the 'Build number' seven times.
You will get a message telling you that you are now a developer.
Return to the main settings page and a new option 'Developers options' will be visible.
B)Click on 'Developers options' > 'Select runtime'. Then click 'Art'. This cause android to rebuild the runtime system & libraries. When its finished optimising apps, use the tablet as normal for 10-15 minutes, note some apps will NOT function properly.
Restart tablet by powering off and turning back on.
C)Goto main 'Settings' page click 'Developers options' > 'Select runtime'. Then click 'Dalvik'. Android will rebuild the runtime system & libraries and return the tablet to its original state. When its finished optimising the apps, Power off the tablet then restart.
I hope this helps… (does not require unlocking or rooting)

So phone worked fine running AOSiP current Pie then out of nowhere when I would reboot I'd randomly get a blank screen. Adb and fastboot commands still worked and eventually, after a few attempts it'd boot normally. Then the other day, after running great, I picked it up and was froze at the lock screen. Now every time the screen times out it freezes at the lock screen and can only be unlocked after a reboot, if I don't get the blank screen that is, and only right after booting but if the screen times out at all it freezes. Also, mic quit working for Google Assistant and voice to text in Messenger. Once unlocked everything works great, except the mic issue no freezes or glitches. I've flashed back to stock all the way back to the last Oreo updates and even ran with no restored apps or data and these problems exist each and every time. Any ideas?
My Note 3 has occasional problems during boot and consistent problems during lock screen.
Occasionally during boot instead of seeing the Samsung logo during startup the screen becomes pixellated and unchanging - i.e. a bunch of random pixels. The phone continues to boot up otherwise and the OS works. To buy-pass the boot problem I need to take the battery out of the phone for about 2 minutes (or more) and it would normally boot fine after that. When it boots up I often see a part of the screen momentarily go pixellated before it starts the usual boot loop.
When the devices boots up fine lock screen has problems. When I turn on lock screen the screen remains black thereafter and soon reboots.
I have SM-N9005 with LineageOS 18.1 +microG + Magisk. I don't think the problem is due to LOS because boot problems existed in the previous OS (Android 5), and lock screen problems occasionally came up. I hoped installing LOS will sort out the problems, but alas... I have tried using an app called Wakelock v3 to sort out the screen lock problems in the same way as for Note 4, but the app seems to have made no difference. Since installing LOS I have not had a single successful lock screen, with or without the app.
Any help or advice appreciated.
