Note 2 switches off by itself - Galaxy Note II Q&A, Help & Troubleshooting

Hi guys. Thanks for helping me get my note 2 up again. Now a problem that had been with my phone for a long time; the phone goes off by itself, even when it's on top of a desk untouched. Sometimes it goes off when it's charging and someone's when it's in my pocket.
I have to press the start button for like ten seconds to boot it; otherwise I remove the battery and replace it then press the start button like normal.
I tried flashing new factory roms to no avail; problem persists.
Other thanthis issuethe phoneworks verywell. What can I do to get this phone to work properly?
Thanks guys.

Maybe but I have no idea. How could one solve this problem if it happens to be the one?

From your description it can't be a simple loosened battery, I think its hardware related since flashing new roms dousnt work. You still have warranty?

i dont mean to bash or be mean man and i know it can be confusing but wrong thread. ALL questions belong under Q and A
besides the obvious (wrong thread) I have the exact same issue. LGNPST keeps stopping at 67% or 85% and not working. Then my device stopped working all together. taking it to the store tomorrow.
I just unplugged my phone, let it reboot than plugged it back in and lgnpst finished up after that. It kept freezing at 85% for me.

The 67,85% issue is a bug with the software, but it's not an issue. Your device would reboot then and everything would be peachy.

Does your phone do anything while not plugged in? Mine when i bricked didn't. You may need to take out the battery.

Yes with a torx 5 screwdriver and Phillips 00

Ok! Even though this is the wrong forum...again I apologize. I was able to recover lol.
Heres the story: my phone soft bricked. I had zv8 rooted using the AIO tool and unlocked bootloader using freegee app..support the devs! And was lazy lol.
A friend of mine decided it would be a fantastic idea to allow the OTA for ZV9 to install...needless to say the phone went nuts. Into "epileptic mode" as I like to call it.
The phone would not turn on..at all...unless you hooked it up to usb or AC. And even if you connected to such power options...the phone would only flash the the red notification light and the softkeys consistently over and over like a police car lol.
Even after running LGNPST. It would go back to "epileptic mode" after reboot at 67%. I found this to be annoying....since the firmware was flashing without issue.
I hopped on IRC and fiddy and shelnut2 instructed me to do a battery pull. Thank God for them lol.
I got a T5 screwdriver and a small philips, removed both screws from the bottom and then removed the back cover carefully. Once it opened I peeled back the blue clear tape covering the battery connections and removed the two screws under that (used philips). Disconnected the battery for 5 seconds then reconnected and pressed power on button and finally.....PROFIT!!!!!!
Phone booted with stock firmware from LGNPST.

Does it happen every time or just now and then?
Because I never had this issue myself.
Out of curiosity what region or country is your phone software

[Q] NFC not working after turn on the phone awhile?

I have a weird issue with NFC. When I restart my phone, the NFC works normally. BUT after a short time the option cannot be enabled.
Tried flashing new rom with full wipe but the problem is still there.
Can anyone help me please
Sent from my GT-N7100 using xda premium
Maybe some app is killing core nfc processes or something.
Sent from my GT-N7100 using xda premium
It's more weird because after it's not working awhile, it starts to work again without rebooting. :/
Sent from my GT-N7100 using xda premium
So it might have restarted.

Now I'm on Carbon rom which is AOSP-based and the problem is still here. May I have to change something of hardware
Sent from my GT-N7100 using xda premium
Maybe it's due to the fact that the sources for note 2 are incomplete which doesn't allow the nfc to work properly.
Try stock rom

Phone just vibrates

I install battery and phone just vibrates, doesn't turn on
Sent from my SGH-T889 using XDA Premium 4 mobile app
It's probably the power button. S2s have a problem with the button getting stuck internally. The button feels and functions like its fine but inside its not. I've had customers tell me they YouTubed on how to fix. Or if the device is under warranty still exchange it. Hope this helps.

Issues with KitKat

Since updating to 4.4.2 KitKat, my screen freezes often, especially when the screen shuts off and goes into the lock screen. In order to fix it, I have to take the battery out and put it back in for it to work properly until the next time. Is anyone else having this issue? Is there any way to fix it?

I would do a factory reset and a clean install. Might have been a bad download.

It was an OTA update. No downloading or flashing
