S3 doesn't turn on when plugged in

Whenever I try to turn on s3 when it's charging and powered off it shows the Samsung logo then goes back to showing the charging logo and doesn't turn on. Anyone else experiencing this?

Its normal. Acts weird if u try to turn it on when plugged in the s2 was the same way. U have to let go of the power at just the right moment. Best way to get around it is to hold the button combo for download mode(vol down+home+pwr) when the warning comes up just hit vol down and it will boot as normal

You have to hold power until it vibrates.

I do hold it until it vibrates but it still loops back to the charging screen

I had the same issue last week. Couldn't get it to boot at all, I was able to go in download mode but it quickly powered back off. I ened up taking it into BestBuy as i just signed up for their insurance. They gave me a new phone out of box after trying themselves to get it to boot.

Problem gt-p5210 tab3 10.1.

I mean, I had the tablet on my desk with battery, more than 20%, and when I wanted to use it it was apparently off, it took me 5 min for starting, pressing the off button and then the volume. Has anyone ever been happen the same thing ? It was bought on March 2014, the last 4.2.2, and it has not given me any problems so far, without rooting. Thank you

Problem when charging
I recently installed the firmware 4.4.2 from Canada and I noticed when I charge the tablet can not turn off the tablet, I mean, if I charge the table on and turn off after few seconds the tablet turns on again, this happens to any one else? :silly:

Listen I have no real answer as about what happen. But I can say this for sure. We can not take the battery out. So there is a feature to do a software battery rest.
Just like Win7, Hold the Power Button for about 5 second and It will mimic a Battery disconnect, Do not do it longer than 10 seconds is a waits of time. If you are not sure you press it correctly, release it and try again but this time look at the button.
Now here is an issue. Depending where you are Holding JUST the Power button can behave differently.
A) Holding Power button forever, starting from Home Screen
..1)Turn your TAB3 ON and swipe to be in Home screen.
..2) Lets Press Power while holding, NO Release, so that wee can see what it does.
..3) You will see it will Power OFF, Then Restart. Nothing more Happen, just wait for ever on swipe screen.
B)Holding Power button forever, starting from POWER OFF
..1) Now use the normal procedure to turn your Tab3 OFF. Let it alone. at least a minute to make sure is OFF. Just for test purpose.
..2) Lets Press Power while holding, NO Release, so that wee can see what it does.
..3) You will see it Turn On, see the Samsung Logo and Turn OFF. Black Screen for ever will follow.
So as you see, it is possible you had your table OFF when you where continuously pressing the button!. Normal Behavior.
As for Why when Off, I do not know but I seen my table freeze from time to time and and even go off.

Yes It does, charging while device is OFF. Some time it does not like to respond. In fact there are claims that 4.4.2 does not charge while off. If you have a kernel modified the you will see the BIGG Battery symbol. But still it is hard to respond.

I don't know if it is hw of sw problem is weird

That did not help, but I was able to turn on in Download Mode and for it functional normal again, I had to Use Odin and re-root it again.

Tablet won't turn on / charge

Hi,
I've only had my Samsung Galaxy Tab S for a few weeks. Whilst on a plane the battery went to 0%.. no problem I thought as I'd simply charge it when I got to a power source.
However, when plugged in, nothing happens. No LED light, nothing on the screen. I've plugged it into a wall socket and via USB into a PC. I have held down the power button, home and volume down for a period of time, as well as just the power button and volume down.
Has my tablet gone kaput?
Cheers,
Titanium

I'd just let it charge for a while. It'll take a bit before it comes back to life if it was completely drained.
If you still don't get any response hold POWER + VOL DOWN.

Should it show any lights? It's as if it's not even charging at all.

If it was powered off I'd expect the battery icon to show.
Did you try holding POWER + VOL DOWN?

Yeah, tried to hold it down. No LED lights and nothing shows on the tablet. It's as if it's just dead.

There are no leds.
I know someone else had the same problem. They used a different charger and it worked.
Try that first.

I had this problem.
You'll have to pry off the back cover, remove the wire that connects the battery to the motherboard. (A battery pull, basically).
Keep it off for 30 seconds. Then plug back in.
Use ifixit for details about opening. Feel free to ask for more help.

Try this one.
1) connect the tab to PC
2) press Home, Vol Down and Power simultaneously up to a screen appears;
3) press Vol Down to cancel and reboot the tablet.

Now there are a few things you can try...
First check your charging port for any dust or any foreign particle. There has to be a small gap between the base of the charging port, and the small slab above it. Carefully, using a board pin, try and push that slab a bit up, don't apply too much pressure, just enough to make it move slightly!
This can happen sometimes if you drop your phone.
Next, make sure your charger, and the USB cable are working fine.
Also tell me if you have any Xposed module for your battery installed on your phone!

Thanks so much for that.
This morning, I plugged my tablet in to AC charge before leaving for the day -- battery was at ~30% and all was well. This evening, I came home and the tab was stuck at a weird Samsung logo -- not the normal boot with colored ovals, but the logo surrounded by a moving star field, never seen before, and could not get the tab to respond, turn off, do anything. Tried many wacky suggestions found on the intertubes to stop/start it, including holding power plus touching the screen for > 30 seconds, none of which worked. Never would have thought your suggestion for download mode would work, but it did on the very first try.
I'd like to know how the tab got into that state, and what that star field logo is about. But at least it's working again, for now.
Thank you.

That's the normal lollipop boot screen.
