I own a Samsung Galaxy Note. I have seen that very randomly and infrequently, my device just turns off on its own. I then have to restart it by pressing on the power button.

Yes, the device has enough battery life left in it.

I have seen the same behaviour in my previous Samsung Galaxy S as well. Any one out here experiencing the same, or does any one know why its happening and what I could do to fix it?

I had the same behaviour, related to frequent "driving mode" madness. I don't know if the driving mode is an effect of the same cause or not, but when one stopped the other did too.

What I did to stop it (some might be BS, but It didn't do it a second time, so I can't find out what was the help)

  • Dry it off (some rain might have gotten into the USB port)
  • Clean the usb port.
  • Shut off, remove battery, wait 10 minutes
  • Restart.
  • Connect to wall-outlet-charger (full charge, as opposed to computer charge)
  • Stop charging it with el cheapo, very thin, shaky cables.

Yeah My Samsung Galaxy S2 behave like that sometimes... I thought I pressed the power button for quite too long (I was using an annoying skin fit cover). But now that you mention it, Yes it happens. But ever since I am using Amzer covers there has never been a problem like that. Yes the some weird app eats up memories and shuts down the phone, but it is not turning off anymore.

I have upgraded to ICS and havent seen this bug since then. –  rfsk2010 May 28 '12 at 14:11

I had a problem with the phone rebooting apparently without any cause about once a day, I only realized that because it played the boot sound. I think that was because the case I use might fit a little bit too tight and in some situations pressed the power button for a long time which, if I do that intentionally also initializes a reboot.

I have adjusted the case and haven't experienced the problem since then.

Not sure about other Galaxy devices but the Note 2 shuts off on it's own under various conditions, all hardware related. Take a look at this video: http://www.youtube.com/watch?v=SjLn2yikYnI and also this site I built that goes in to more detail regarding the issue: www.GalaxyNote2ShutsOff.com

One look at that short video and I am sure there will be some light bulbs going off. Be sure to read the details I provided on that site as well. They go in to detail about the problems that I have had and the lack of proper support that Samsung is willing to provide.

Yes, It is a "Loose " battery issue. I had the same problem with my galaxy xcover and cured it totally by adding a layer of thick adhesive tape at the end of the battery in order to press it harder against the contacts, and 2 layers of adhesive tape at the back of the battery in order to keep it more firmly in place. Problem solved !!

When you put wifi in sleepy condition, it keeps CPU busy & overloaded putting wifi on and off frequently, so putting wifi never sleepy condition the CPU is less burdened & more efficient, which ensures phone never shutdown on its own.

Welcome to Android Enthusiasts! I very much doubt it will "overload" the CPU, nor will it make the device "never shutdown on its own" (if the battery is empty, it will still do so). I can't even see how this is connected to the issue; mind to explain? –  Izzy Jun 23 at 14:59

i had the same problem , my phone switches off and on for about 20-25 times a day ,, horrible isnt it , well .. !! this is wat i did to over come this problem , and it worked fine . go to settings > wireless and network > wifi settings > using menu option choose advance settings >wifi sleep policy > select "never" > press menu option and save .. have happy time :)

What does the sleep policy have to do with shutdowns? This seems like a red herring. –  Al E. Apr 2 '13 at 12:24
