[Q] power down bug?

hey guys.
i just want to know if you guys can replicate a problem i found and see if the problem i have is isolated or not.
so i've been charging my phone today and noticed that when i try and power down the phone while it is charging, the phone hangs at the shutdown circle and freezes.
when i unplug the charger (wall charger), then the phone immediately turns off.
at first i thought it was because of low battery ( i ran the phone until it died).
then i thought it was because i had no wireless connection (was in building-no signal).
when there was enough juice, i shut down the phone (not charging this time) and the phone powers down.
if this has been already covered, i apologize...
sorry for the bad grammar/punctuations. im feeling lazy. lol

defective NS?

My phone powers down while plugged in just fine. I just checked for you.
It takes about 30 seconds of the spinning shutting down message, then the screen switches to the battery charge icon for a few seconds, then the screen goes black.
A quick press (don't hold) of the power button brings back the battery charge icon for another 10 seconds or so.

Thanks for the reply. What is weird is that I tried the test at my local best and their demo phone was exhibiting the same thing. Maybe I'm not letting it shut down long enough.

okay, i've powered down again while charging. stuck on power down screen.
been over 2 min.
looks like i'm replacing this today.
anyone else want to chime in on this?

Since you're going to have to do a factory wipe/reset for privacy/security to exchange the phone anyways, can I suggest that before you assume the phone is bad that you perform a factory reset on it and then test again?
For all we know, you've got some rogue app that is causing the problem. I'd hate to see the NS returned as bad hardware when it might possibly just be bad software you've installed...

exactly what i plan on doing. gonna do a factory reset first.
But i think it will still happen because the demo unit at bestbuy was a clean install with no apps on there.
But i will update as soon as i restore!
thanks distorted!

wanted to add that when i shut down the phone while it was usb connected to the comp, it shut down properly and i saw your battery icon you were mentioning.
edit:
now i tried other wall plugs, usb cords and such and it all shuts down.
very weird.
It looks like it was the micro usb charger that i was using that was the problem.
I was using one that came with my blutooth charger.
I double checked all the information of the BT plug and compared with the ones that worked. the bluetooth cable was rated a .7 amps (just like the one that came with the nexus s). other cables were rated at 1 amp (which shut down the phone fine).
oi! saved me the trip to best buy.
i tested before and after factory reset.
all good except for the BT charger.

I can confirm that this is an issue. I have a spare micro-usb cable, and when I connect that to the computer, it charges fine, but the usb-debugging or usb-drive options never appear.
While it's in this state, and I go to shut down, the Power off - Shutting Down... screen will in fact freeze until the USB cable is unplugged. It does not do this with the stock usb cable.
When this "bad" cable is used with the stock wall charger, the same thing happens.

Hmmm... I wonder what can be causing this. Anyone else have this happening?

My best guess is that maybe there's something different with the pins and they are shorting/not aligned right in some cables.

Screen doesn't respond when plugged in wall charger.

Yesterday I missed a call because screen didn't respond on touch, I was blaming on tithering (which by the way had rebooted phone twice today), but today I've noticed when this happens and I unplug the phone, it instantaniosly fixes the screen (and buttons as well), plugging it back in, freezes it. Was playing with it for a minute just to make sure..
Anyone experiencing anything like this?
P.S.
Installed "CPU Guage" which shows cpu load in real time in tasks bar, I can see the numbers changes but nothing above 30%, so it wasn't CPU overload

i haven't had that, until about 2 minutes ago. funny this was posted just now, i just logged in to post about it, lol. but my phone has been fine, until just now. i plugged it in and when to change it to mass storage mode and it wouldn't respond. then it was kind of weird when it started responding. it eventually worked, but took a couple of swipes.
---------- Post added at 06:39 PM ---------- Previous post was at 06:37 PM ----------
i also notice that when unplugged, i get around 44-45 linpack, plugged in, around 35

Nope, just tested it, plugged to the wall I could answer a call normally.

it might be because of short circuit, check ur charger or charge with another charger or cable see if it happen again.

I have it too. Anytime its plugged in it will be super laggy and/or freeze.

I haven't seen this issue on the Atrix 2 yet, but both my Samsung Moment and Samsung Epic would have screen responsiveness issues while plugged in, so it is behavior I have seen in other Android devices.

I havent had this problem. When I go to bed I put my phone on the charger, wall type, and will usually mess around on the phone for a little while before setting it down for the night. Not once has it given me this problem.

I don't have this problem all the time either, it happened only twice in two days. Just now checked it again - no problem whatsoever...
Perhaps if we trace what is running and/or what was running before this happens, we could figure something out.
Today I was using pandora, sportypal (which by the way consumes 40% cpu at times, on Atrix 4G never had this problem) and then after these two apps where closed I used mobile hotspot.
On background two apps are always running: battery cyrlce and nettraffic (there are many more apps started but they seems to be inactive, like skype which doesn't log me in automatically)
Oh and it could make difference, I use ADWLauncher EX

I don't have any of these problems. Get up every morning and check missed calls, emails, texts and FB notifications all while being plugged into the charger. Had someone call me and I answered it on speaker phone to make sure I didn't have any problems receiving a call while plugged in either

No problems so far, but I am completely stock. Phone was purchased on the Nov. 11th
wow, just had it happen.

Don't have this problem either but I am completely stock also.

I don't seem to have this problem in the morning either, I notice it at about 11am - 1pm
Today I've killed every apps that was running (excluded services), but it didn't help at all. I still suspect mobile hotspot though, it doesn't work properly...client's get disconnected, then would not able obtain IP.

OEM charger and cable only
Make sure you are using ONLY the OEM charger and OEM cable to charge your phone. They provide an extra ground path not normally supplied which is needed by your capacitive touchscreen to function normally. A "normal" micro USB cable or USb charger does not provide this.

I have a charger by my bed, a charger in my work van, a charger at my desk at work and a charger on my pc....of all those, only the one by my bed is the oem charger and the oem cord, my phone works perfectly on all of them.

Ok, it has nothing to do with the type of charger, it even happens when connected to PC as storage or charge only. Changing cables also have no affect.

Me too

I had this happen A LOT! Happened almost always with one particular charger, rarely happened when hooked up to computer USB port. Never happened in car using Griffin iPad car charger.
This was one of the frustrating things about the phone for me. Just sold, and have Galaxy Note on the way.

Hey people I have this similar issue... was searching xda for anything like this but seems this is the only place there is some issue like this happening...
I have a Galaxy S2 Running Cyanogen7 ...
Now here's what IV noticed... on stock charger I have no issues at all... nor when plugged into the PC... just today it happened and I was using a iPhone charger with a OEM Samsung USB cable... it was charging fine but the screen just wouldn't respond... as soon as unplugged would be fine... so... I'm thinking it's this charger maybe giving too much power to the phone... as my stock charger is 750ma while the iPhone one is 1A... that's the farthest IV been able to think... :s

motorola contacted me to send them my phone and car dock, and they would swap them with new units so they can use mine with testing. you should go to the motorola atrix 2 owners forums and talk to mark

I've owned this phone for roughly 36 hours. I noticed last night (which is the first night owning the phone) that when the phone is charging, it doesn't seem to acknowledge my finger touching the screen. Since the phone was new, the only apps downloaded at the time were:
Lets Golf 2
Angry Birds
Tiny Bee Demo and,
AVG Anti-Virus
Things to note:
I did download the 3 games before the anti-virus program, so the possibility of a virus is there, but not likely.
I also didn't delete any apps or change any major settings that might cause the problem.
One other odd thing I noticed, I was in the middle of a text when I plugged in the charger, and that somehow made it insert a letter. I thought it was odd so I made sure it wasn't me touching the screen and tried it again, and it typed two other random numbers.
I hope this helps somebody somewhere find the fix to this problem... :cool
Edit: I have an Atrix 2

P6810 suddenly won't turn on

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?

[Q] Charging oddities while phone is off

Hi,
Last year my girlfriend allowed me to root her Sensation to try out different ROMs and all went well. A few months ago however, she started to have problems while charging her phone.
If she plugs it in while the phone is closed, the orange LED flashes on/off at around a 2 second interval, instead of holding it's colour. Furthermore, it never changes to green to indicate that the charge is complete. When the phone is in this state, she can't turn her phone on either - she has to unplug it in order to turn it on. If the phone is already on, and she plugs it in, everything behaves normally.
Either than that, the battery seems to hold the charge normally and the rest of the phone still works very well.
I've tried searching for similar problems but haven't landed on anything similar or which may be helpful. It's really got me stumped to what could be the cause, and more importantly, how to fix it!
Would someone have any ideas?
Thanks!

Does the phone behaves in same manner if it's fully charge n switched off when plugged to the charger.does the orange led fluctuate.
The orange led fluctuate whn the voltage of charger is less and it takes times to charge try switching the charger means if you use wall charger then charge through pc and vice versa
Hit thanks button if you find me helpfully

We tried switching from wall plug to USB on the laptop and it does the same thing. However, we noticed that if the battery isn't completely drained, the led doesn't flash - it charges normally.
Would there be a way around this?

I'd pick on the odds that the LED light hardware controller is slightly faulty, but if its really like you said its nothing to worry about, right?

Hi,
greetings
this used to happen with me when i was on stock rom.
the problem is when the battery is completely drained it needs lots of voltage to get charge
for this problem i took my cell to htc service center and they replaced the adapter and the problem was solved
i think you must buy a new adapter or say a new charger i thing that must solve your problem of led and your phone will get charge as normal even with the battery completely drained OR i think we get wall chargers you can look at the picture in which we have to place the battery and the battery gets charged you justt have to put the battery.. this charger is locally available in indian market for 80 to 100 rs.. you can search on net for the charger this is really a good thing and is a universal charger chagers each and every battery here in india we call it as khekda (marathi word for carb ) charger
let me know if it does solve your battery

Pixel 2 says it is always charging / will not charge

Recently got a Pixel 2 and it sometimes has this problem:
* Battery icon indicates that it is charging, even when it is not plugged into anything.
* When it's doing this, if I plug it in, it will not charge (but still indicates that it is charging)
* If I notice this and restart the phone, it resumes working normally.
Anyone else experience this?
Any ideas on a fix?

My Pixel 2 will get stuck at 100% after being charged overnight, under the battery settings it states that the battery information is not available. So far a reboot will fix the problem, I haven't allowed the phone to stay in the 100% state for long without a reboot. Today I'm going to leave it at 100% to see if the phone corrects the issue eventually during the day...report pending.

same. i noticed it today for the first time today. plugged it in (not the charger that came with the phone, one used for my s7 with a usb-c cord) 20 minutes later noticed it hadn't charged any even though it said it was charging, and the level had actually went down. power cycled it, now it's charging again.

I just had that same problem on my pixel 2. A single reboot didn't help, but a second reboot fixed it. Weird....

Same issue. Plugged into car, says charging, levels dropping, even after reboot. Tried different cables and charger, no difference. Wife just walked in and said her Nexus 5 is doing the same thing! HEY GOOGLE, what did you send out to cause this?

This happened to me today too, right before I was going to update to 8.1. Phone said it was charging all day, even though it wasn't plugged in. A reboot didn't fix it. Then tried Turn Off, and it rebooted and now seems fine.

Having this right now. A few reboots and even shutting the phone down hasn't helped so far. Will run the phone empty to see what happens.

Happens occasionally to me as well. I often disconnect charger from the power rather than pull the charging cable out of the phone first. I wonder if the relatively slow fall in charging voltage when I remove power from the charger makes the problem more likely.
For those who have this problem:
Are you using original charger and cable?
Are you terminating charging by disconnecting power from the charger first, or pulling the cable out the phone whilst power is still on?
Is the phone screen on when you do it?
Anyway, I find a "hold the power key on the phone down for many seconds until it turns off" reboot fixes it until the next time...

1. I was actually using the portable charger that came with my 6P. The Pixel 2 isn't available in the Netherlands as it came with a UK plug.
2. Both methods had the same behaviour. Normally I pull the plug from the socket first before going unplugging it from the phone.
3. 20% of the time the screen is on and the phone unlocked. Most of the times it's just active display.
The phone eventually died despite being plugged in. I started charging again when I used one of the regular chargers (cord not separable). And not it works normally again with the portable charger.

Was this without rebooting the phone? I.e. you fixed the problem just by temporarily plugging in a 'regular' charger?

The phone was dead so I'd consider it a reboot. I left it on the charger to get a full battery again. The problem was gone as I did a check 45 Mon after plugging it in.
