[Q] Samsung or Android flaw?

Ive discovered this by accident but while the phone is in standby modus and and the screen is locked, when you press the powerbutton for ~5sec the phone reboots.
In my opinion the "reboot" function mapped to the power button should only be working when the phone is screen unlocked.
Is this a samsung or android thingy?

what do you mean by stand by mode ? when screen is off and not being used ? this doesnt happen on my device...
just dont press the power button for 5 seconds and hey presto !!! job done lol

isn' tthis good feature?
It may help a little when
a. not able to 'wake-up' a sleeping phone
b. upon waking-up , force close message keeps on appearing
In b, i have to take out battery and when using my case-mate barely there cover, it's inconvenient to pry it open.

oops.. I didn't answer your actual question.
Sorry, dunno if this is Samsung thingie or Android thingie. But I can "reproduce" the effect on my phone.
It's not reboot though - it goes to "switch off" mode

mine comes up with a message to shut down the phone or enter flight mode or silent mode or data network mode if you hold down the power button for 5 secs in stand by mode.
If your not getting that message first its possible that your firmware is faulty or if its not a stock firmware it may have not been added correctly.

same here i get message.. stock jpy with speedmod kernel

No i meant like for example you put the phone in your pocket like you normally do and the powerbutton gets pressed for ~5sec while your bent down or another position the button gets pressed it would reboot. Im not really happy with that happening would you.
Im on stock js3 onlything i mod was putting the voodoo kernel on it.

Its a good thing
You'll be happy when the phone freezes and you don't need to take it apart to reboot it (pull battery)... Its just like a power button on a PC, if you hold it long enough it shuts the device down. I've never done it by accident though. Just get a $.99 plastic case and your problem will be gone but you'll still have the feature.

[Q] Galaxy note functional but screen stuck in 'sleep' ?!

Hi Guys,
I have a frustrating situation whereby my Galaxy Note powers on but the screen appears to be in permanent sleep mode - I get nothing but black on the screen.
You can here the Samsung chime as the phone powers up, I can adjust the volume button and hear audible tones. I can also call the mobile from another phone so the underlying phone/OS is working fine.
I can also connect the device via Kies USB and copy images/music with no issues.
I have tried removing the battery and replacing, I have also tried giving the device a full charge however I still get nothing on the screen.
Does anyone know if it's possible to perform some kind of hardware reset to get the screen to power back on? If not I guess i'll need to return the unit
p.s. Stock Galaxy Note
Thanks v much
Jeremy

Same problem for me , i have test many ROM and kernel but i still get the black screen. it's generally when i haven't use my phone during a couple hours.

Same issue here. The screen remains black and not responsive to front button or power button. I still am able to hear notifications (e.g. calendar reminders, plug in power, etc.).
Long press of power button to reboot is the only solution I have found in order to clear.
First occurrence yesterday after owning note for 1 month.
Second occurrence today.
Stock device. No root. KL7.
No newly installed apps prior to first occurrence. I will cross-check to see if any apps updated yesterday.
I have also disabled Green Power.

guys i have been owning note since past 45 days
and suddenly i faced the same problem today
when phone is in sleep and i receive a notification and press the home button
to wake the phone
i see only a black screen with a minute pink dot at top right
and the phone wont respond
however pressing the power button it brings the menu to switch and etc
so i can select power off and then again switch on the phone
guys this is frustrating
please help

Menu, Home, etc keys aren't lit up anymore

My home, menu, search, etc keys are not lighting up anymore. I tried restarting the phone to see if it would get em lit up agian, but no luck. I can go into Settings > Display > Adjust Brightness, but whenever the phone screen locks they go off again until I do the above again.
They were lit up fine until I tried to enter CWM recovery by holding power and vol down.
Phone is rooted, 2.3.4 update, stock rom.
EDIT: I have no idea what I did to fix it but it's fixed now =/.

its a known bug, usually after charging it will go back to normal. nothing serious.

Hold the phone up to a light while the screen is on. It can be anything from a flashlight to a computer monitor.

Go to Display. take the check-mark out and reboot. Then put the check-mark back in and reboot again. Hope it works. Its a GB thing!

This is the best solution I've found for this problem. Flash a light onto the phone censor. Or just hold your phone up to a bright monitor like he mentioned. Fixes it every time. You'll probably have to do this every time you reboot because that's usually when the problem reoccures.

if you add the brightness widget to one of you screen and then use it to adjust brightness, it will light up the buttons

[Q] [URGENT] Screen frozen then goes black

Hey, I received a notification on my watch, so as I go to look at it (the screen is always on mode) the watch is frozen in ambient mode. When I hard reset it, the screen just goes black but I still receive vibrations upon various actions. Any ideas? I really hope the screen isn't dead. There have been no other signs of damage...
The watch is connected to my phone.

Can you enter in recovery? Try a factory reset.

Well I mean I can't see anything on the screen so I'm unsure how to go about doing that
The device also does not appear to have a reset button at the back

Press the button of the watch loooooooooong, until it starts and stops vibrating continuously (first you will feel a short vibration then a very long one.... you need to keep pressing the button while it vibrates for the long interval as well).
After the long vibration the device will restart ... IF you see the LG logo, swipe from top-left to bottom-right of the screen ...

Thanks for the suggestion, but the screen remains black. Note I also do not feel a short vibration beforehand.

Sorry .. the short vibration will be felt only if the watch is awaken. From the dim mode it goes directly to the long one.
It seems that your watch has a problem. you can try to access it through ADB (if you enabled it) or you can just leave it until it will become completely depleted and try to revive it again afer that.

see this post: here
activate warranty is the current solution
I have the same problem, with no warranty so the watch is just sitting there for now

Connect to pc to back your data up. Also does the touchscreen work? And did you drop your phone or something else?

the touchscreen doesn't work
debugging mode is not activated, I cannot transfer my data to the pc.
I had the touchscreen bug for some time and suddenly, the screen did not turn on. The phone did not fall.

If it still under warranty i would send it to where you bought it. Even if you dont have warranty try it because the device should not be broken under normal use.

keep pressing the power button and when your phone vibrates try and hit restart. i know your screen is blacked out but if possible just try and locate. it happened with me too and thankfully my devices' screen recovered. the pop up comes just adjacent to the power button. first option will be your power off and then just below will be your restart.

I already tried
the phone reboots well but still black screen
