GS9+ shutdown after unlock the screen - Samsung Galaxy S9+ Questions & Answers

I am on stock ATT rom. Since this morning, every time I unlock the device (I didn't enable pin or fingerprint, just swipe to unlock), it will suddenly turn off within few seconds.
As long as I stay at lock screen, it will not turn off at all. otherwise it will just turn off by itself. There is no notice saying the phone is turning off, It just go directly to black. I can still go to stock android recovery, I can charge it.
Any idea?

The phone actually powers down? Where as you have to hold in the power button to turn it back on?

Power button broken? Wont boot up, wake up or sleep properly.

I am sorry for the noob post, I think that this is my first post.
My Transformer prime has a serious issue. I bought it in March and everything was wonderful until suddenly one day it refused to start up completely
It would vibrate, show the splash screen and then "asus" and the litle waiting icon, then the screen would go black and it would start over and do that over and over and over.
I read about the pin hole reset and it didnt change anything no mater how long I held it. I held the power and volume buttons to get to the built in recovery and it would still only work for about 10s before turning it self off and starting over.
After about 3hrs of trying everything I could think of I found a work around:
It will only boot if I hold the power button down the entire time that it is booting.
However, the power button doesnt do anything anymore. If I hit it the tablet wont go to sleep, I cant shut down the tablet with the power button, and it wont wake up with the power button.
In addition, at random intervals, my tablet will interrupt me and ask me if I want to shut it down.
If it does shut down, the only way to get it to turn on again is to plug it in and then hold down the power button until it boots completly.
I am fully stock, I dont know if I am rooted or unlocked. (sorry, Im a noob)
Please help.
I have the keyboard dock which is the only way I am able to resume from and put to sleep.
This problem occured under .21. I have since updated to .28 and no change. Factory reset and full wipe, no change.

when you start up the tablet, does it say unlock on the screen anywhere? *i believe it does....) if it is, you cannot use the asus OTA updates or it will break your device
i think your best bet is to do a RMA...

[Q] How to know if my Atrix is on or standby?

It is a weird problem. Not a killing one, but still it's absurd.
How would I know that my phone is sleeping (standby) or completely shut down (off)?
You may say, just press the power button on backside. But if I do that, that's going to turn on the phone anyway if it was off.
I want to know without turning the phone on whether the phone is actually off or not.
Any idea guys? Any way to find out?
[PS: This is my first post. ]

When you press shortly on the power botton- if the phone is sleeping the screen will turn on to the lock screen, if the phone is off it will turn on to the red M initial screen.
That is a really weird question, why should you ask it? if you turned your phone off it is off, if you just turned the screen off it is asleep (shhhh, don't disturb him :silly: )
:cyclops:
I don't want to disturb him, that's what I want.

If the phone was sleeping, I would know as it will show lock screen when I press the power button. But if it was off and I press the power button, it will turn on the phone. And I don't want that. I just want to know whether the phone is off, and if it is off I don't want to disturb him.
In other phones, they have separate unlock button, here it is combined with power. That's the problem. But moto could have made long press for turn on and short press for unlock. I think there is no solution to my problem. :crying: Thanks anyways.

Call your number?
Plug in the headset and press the headset button?
Plug in the charger?
Pair it with wifi/bluetooth and see if connection is alive from paired device?
I'm sure there are hundreds of other creative ways to find out whether the phone is off or on standby without pressing the power button.

I know what you mean, like in the Nokia 700 (or any symbian phones), there are two seperate buttons, where the lock button does not switch on the phone, but instead the power button does. I know some Android devices need a long press to switch on, while a short press does nothing while off, but Motorola doesn't use this "feature".
Sent from that Atrix.
If you use a CM based rom you can set the volume rocker to wake the phone. If you use a blur based rom you can install an app from the play that does the same.

Thanks!

Or use light flow app and turn on a led indicator for phone signal.

Lock screen not turning off unless I do it manually (5.1.1)

I am not sure if this is a bug with 5.1.1 or not. I tried searched before coming here to post, but I haven't come across a solution yet.
Anyways, my phone doesn't have power saver on, smart stay is off, and I have my security set to fingerprint unlock.
To the issue at hand - My screen doesn't automatically time out if I press the home button or the power button to turn on my screen. In order for the screen to turn off, I have to manually press the power button. Otherwise, the screen just stays on and drains my battery. This wouldn't be too much of an issue if my butt didn't always press the home button while the phone was my pocket.
I'd really hate to factory reset or flash another rom, as I just finished installing all of my apps and whatnot after a phone replacement. However if that is the only option to fix this problem, then I'm okay with doing so.
Thanks ahead of time for reading!
**quick edit** - forgot to mention that if I receive a notification, that it turns my screen on and keeps it on until I press the power button.

Lock screen on 4.3

Can someone on JB 4.3 confirm if the screen locks by pressing the power button during a phone call ?
I'm guessing we are all on L....
there is a setting in assistance that can use power button to end call. so it depends on that setting on or off
With the setting off because if its on it would end the calls
The reason I'm asking is because my phone calls get discocenected accidentally when I put my phone in my pocket while using a Bluetooth. Since the phone doesn't lock when I press the power button, the proximity sensor turns the screen on while in my pcoket and the end button gets pressed accidentally.
I remember "not" having this problem on JB

Yes, the screen turns off, but the call is still there.
But does it lock? Do you have to swipe to unlock it?

No, just press the power button again, the screen turns back on, and the call screen is still there. Repeat cycle.

How to switch on Xiaomi Mi4i without the power button

Hi,
My phone has a faulty power button and I'm unable to get it fixed. I've found easy work-arounds for it for locking and unlocking the phone. However, I'm not sure how to turn on the phone if it's switched off.
When I connect the charger, even if the battery is 90% it won't turn on on its own...

Have you ever solve the problem? I've also the same faulty button..and I don't know how to power on without this button

Nope, the only way I could turn it on was to open the back cover (very painful process) and then press the button area with a pin.
Couldn't get it fixed, so I had to change the phone.
I think there are possibilities in rooted phones, but otherwise the best thing to do is to keep a battery alarm at 30% or more, and keep it on charging whenever you can to avoid a power off. In power on, there are many ways of locking the screen in the MI UI.

Thanks. I installed Blocco Schermo - Simi Studio v.3.21 , a simple app to lock the screen...and when i flagged the option "show in notification area" , the problem magically disappeared.. The Power On/Off button started to work again. I think it was an hardware problem (because the problem has come up after the phone was at the sunlight for hours in my car and went very hot) but now i think it's obviously a software problem.
Hi guys, I got the same problem too. Unfortunately, I drained my batt while playing games. So the problem now is I can't turn it on. Any idea how to turn on the phone without using the power button?
I solved it
Hi guys i solved a problem! You should hold main button + down volume button for 10-20 seconds. Then, when MI Remote opens, stay on the reboot and wait about 3 minutes, then stay on the reboot systems as well. Great work!
just change the volume flexible. its also not took much cost.
