Anyone come across this? I put it on standby last night after reading a bit of my book on it, and it had around 50% power remaining. This morning, it was totally unresponsive; pressing the power button does nothing at all. I've charged it for 12 hours in the meantime.
I've done the following all with and without the power attached:
- Pressed and held power for 15 seconds through to a minute
- Pressed and held volume up with power to attempt to get into recovery for up to a minute
- Pressed and held volume down with powerfor up to a minute
- Pressed and held power while touching screen (read that one off another forum)
I guess potentially it could be on and in a crashed state and unresponsive to the power, so maybe in a weeks time when it runs out of juice, I'll be able to charge it and power it back up, but in the meantime, I'd welcome suggestions.
A few weeks ago I updated it to the official ICS build that was released, but did the update myself rather than using KIES, as KIES didn't even recognise my Tab's firmware original version. It's been absolutely fine before the update, and since. I only mention it because I've read about the Samsung build of ICS being prone to self bricking itself, but I couldn't determine what the symptoms of this vulnerability were.
Thanks for any help offered,
Will
did you try connecting USB cable and plugging it into your PC? did u get any activity? can ADB recognize your tab?
I think your tab just ran out of juice and the battery's protection circuit has kicked in. Try taking it to an electronic shop and plugging in different chargers preferably one with an output more than 2.1 amps to kickstart the charging. Plug it in and wait till the charging animation starts.

Had the same problem while on holidays. Once the battery goes below a certain level, you won't be able to charge it through USB any more. Instead you need to use the wall charger.
I think it's bad enough that the 7.7 doesn't have a micro USB port, but things like that are just stupid and Samsung made a big mistake here. It don't think it's the same with the newer tablets though. It's also not possible to just buy cables or chargers for this strange Samsung port, so when you forget your wall charger at home at some point you won't be able to use your tablet any more.
As long as you charge with the USB cable early enough, you can avoid it though.
A few months ago I experienced the same thing, the Tab just wouldn't turn on anymore.
I tried all there is without any luck.
Contacted amazon and they replaced it with a new one in less than 48 hours.
So far not Problems with the new device.
I have the P6800 and this morning I took it off charge. Put it into standby and only used it for about 20 mins then left in standby all day. It had about 95% remaining when I did so.
Picked it up this evening and the lower left area of the screen was warm and it would not switch on. Didn't think of the ADB idea but will try this next time but I had to reset it and when it powered on tonight after the reset, it was down to 15%. Within about 2 mins of checking stuff it was down to 3%.
Something is running when it is in standby but as I can't switch it on I can't check with BetterBatteryStats or CPUState to know what is wrong.
It does this every day. I am tempted to do a factory reset and reinstall only limited software.
Dave...
I see this thread is a little old but this has just happened to my P6810 too. A pity nobody reported back what the end result was.
My device had at least 95% battery last night but today I can't get it to respond at all, I've tried the wall charger and still nothing.
Anything else someone could suggest for me?
Edit. I tried getting anything from it connected to my PC but it couldn't find a device there. However I then tried it on the wall charger again and now get a blue battery icon, quite big, with a five step animation indicating that it is charging.
No idea how it went flat as the battery on this lasts a long time assuming the screen isn't on. When it boots properly I'll have a look at what the most recent apps I installed were as it has only done this once. Before this it has been perfect for the three weeks I've had it.

This is the infamous Sleep-Of-Death issue that is randomly experienced by myself and other users here, usually happens when WiFi bugs out due to weak signal

hhmmm, interesting.
I was having trouble with wifi just before this happened. Both my GS2 and this have been claiming to connect to my wifi but aren't actually getting an IP address from it.
I can't remember if it was last night or the night before but I manually set an IP address, the signal strength is fine as my abode isn't very big.
After it has recharged I'll have a poke and see what I can find, thanks for the reply.
So my device seems to be working fine again. It had gone SO flat that the date and time were incorrect!
After I could power it on I had a look at Better Battery Stats and nothing looked wrong so I have no idea what happened. None of the apps I'd installed the day before it played up had long wakelocks and weren't running when I turned it off.
For reference they were:
My Tracks
MyTrails
Google Earth
AndSMB
I'd turned both of the GPS tracking devices off before I turned it off for the night.
It hasn't played up since but it hasn't been long so I'll see what happens.
Yeah, the sleep of death is incredibly annoying. Honestly, the GTab 7.7 is a **** device. Samsung made way too many mistakes and won't do anything to fix it.
A similar thing happens to me every once in awhile. The way i check to make sure everything alright is to see if it boots into download mode. I just leave it plugged in for a couple hours and it eventually comes back on.

this is why my 7.7 is the last tablet/phone from Samsung i'll never trust them they are just bombarding the market with new devices and leaving the old ones to dust
^thats what I thought too but that gs4 is really tempting. I've heard worse about HTC in that regard anyways so that why I'm not going with the one.
Finally.. i bought Sony xperia Z.
I'll sell my galaxy tab 7.7. I.m very disappointed with samsung.

Unbelievable! ... this trick still works ... thank you very much for you help ...
^^ yo, this 'trickle charge' trick did NOT work on my (long) dead P6800... any other suggestions??
Quite strange because my Samsung GT-P6800 tablet was fully charged, it went completely blank dark as if it was off. To my amazement, SMS keeps dropping and calls kept coming in. Yet it is still as blank as though the tab was off. I pressed the power button and the volume up bottom for it to reboot. It rebooted without the screen coming up. It has been blank for two days now. What could be the cause? And what possible solution can be given?
I've had my Nexus for a couple weeks and noticed early on that it would get incredibly hot in one particular spot on the back and wouldn't charge when I tried to charge it from the wall. I'd suspected my power board of being questionable for some time so I chalked it up to that and made a mental note to replace it. It charged perfectly fine via usb so I just did that.
A few days later I crashed at a friend's place and plugged it into his wall charger without thinking about it. The next morning I was really alarmed to find my phone was boiling hot but it cooled down when I unplugged it and seemed to work fine. It wasn't until that evening when I tried to charge it that I realized it now wouldn't charge via wall outlet OR usb OR connect to my computer and instead this one small area on the back would heat up to painful temperatures within 5-10 seconds of being plugged in. Cue panicking.
So I contacted the retailer I got it from to exchange it and during the time they took to get back to me thought "**** it" and ran down the battery. Then before replying to them I plugged it in again to verify it was still broken and for some reason it was back to normal!? It even seems to charge ok from the wall now.
So wtf happened? This still can't be normal, and I can't have a phone that randomly refuses to charge, but how can I convince them there's a problem? What the hell IS my problem? I can't find anyone else with my specific issue. What's the deal?
Do you have a case on it? If so which one?
Nope! Also, I had stock everything. I was planning to root it but now I can't since I might need my warranty... Been trying to reproduce the error but no dice. Kind of frustrating :/
Hai friends, Iam facing a weird issue that whenever i connect my Oneplus 6 to dash/rapid charging, it takes more than 30 seconds ~ 1 minute to activate the "rapid" mode. Untill it charges on the normal mode. At first i thought, it may be an issue with the adapter, but it works fine with my older Oneplus 3. So what to do? Is it normal? Or is it an issue with the phone? I have already wiped/resetted the phone.
That's weird... Flash the latest Full ROM after a full wipe, see if that corrects the issue. If not, live with the 1min delay, or RMA it. Good luck!
This is normal. Most fast charging protocols have a delay built in for safety
And so the pointless complaints begin.
Mine starts Dash charging within 1-3 seconds of plugging in; try a factory reset. If that doesn't work, RMA it.
So my son and I recently moved to Pixel 4a's... Him from a Nokia 6.1 and me from a Pixel 3A XL (screen cracked, otherwise would have stayed with it for a while)... And we both have used Android Auto for years with no major issues, so we are pretty familiar with it. He has a launch model and mine just arrived a couple weeks ago after some time waiting for it to come back into stock from Google.
Both of us in two different vehicles (a Ford and a Hyundai) have the same issue we have not seen before... Android Auto works most of the time just fine, but randomly just acts like someone is connecting/disconnecting the cable rapidly, at the top of the display in the car it shows "Android Auto detected" then the normal display flashes back and forth a few times a second and continues until the USB cable is disconnected. If you reconnect the cable immediately, the cycle usually continues, but if you wait a few minutes or reboot the phone, things work for a while again.
We have tried new cables, with/without case, and clearing data on the AA app, but it still seems to happen totally randomly. Sometimes you can go a couple hours, other times only a few minutes before it occurs again.
Anyone else seeing this issue?
A couple days ago, my (OEM firmware) 3a started randomly restarting even when it was just idle in my pocket. The only thing that I had recently changed on it was to connect some new JBL Endurance Peak II true-wireless earbuds, which I used for a couple of activities. However, even doing a "Forget" on them didn't fix the reboots, so I ended up doing a factory reset and installing a subset of my previous apps to see if I could find the culprit. It ran OK for over 24 hours, so this morning I connected the earbuds again and used them for about an hour with no problems, then put them away. A couple hours later, my phone has just done a spontaneous restart again!
Does it make sense that connecting a BT device could do something like this? The buds are a new product where left & right can operate together or alone, so maybe something different there. Any ideas??
My next thought is to do another reset and this time wait for several days before reconnecting them, or maybe at that point I'll assume they're the cause and return them while I'm within the 14-day return window. Or maybe a newer phone (Pixel 5) might take care of it?
