[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.

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

so i can select power off and then again switch on the phone

[Q] Xperia T, black screen with LED blinking, nothing works, what can I do?

Hi! Sorry for my bad English.
My phone "died" while charging, but the notification LED is still blinking as the phone was just in a normal "stand by" status. Tried to call it from another phone, and it was offline.
This is the second time I get the black screen. It happened the first time 2/3 days ago, that time the phone was just sitting somewhere, then black screen, but the notification LED was blinking, so I tried to call it and it got stuck on the call ringing for like 10 minutes, then I found the reset thing on their site and it worked. This time it doesn't work. Also tried to connect it to a PC while holding the volume down button down, still didn't happen anything. Without holding the button down, nothing happens as well. PC Companion doesn't see it, Windows doesn't see any new device connected. The LED is still blinking. Didn't find anyone with the same problem, and those whith something similar to this, got it fixed with the reset buttons (like I did the first time) or had to send it in for repair... is there anything I can try before having to send it for assistance?
Both times, the LED is blinking blue, like a normal notification blinking, it was probably blinking this way because of an actual notification. It was at around 10/15% battery when i plugged it to the charger, and it was turned on. I didn't do anything to the phone since I bought it, I actually use it as it was a camera that can make phone calls and send messages, never connected to a PC.
I'd rather open it up and disconnect the battery (if that could help) than send it for assistance and maybe get it screwed even more or replaced with something worse...
Thank you!

Keep your xperia T on charger for 24 hours download the latest firmware for your phone and install it with the flashtool.

Thank you, rayenvs, but "nice" ways didn't work.
So I removed the cover and disconnected the battery, now it works again.

Touch screen problems

Hello, I have my moto G 2014 for about 2 weeks now (full stock, never even connected it to the PC). A few days ago sometimes when I lock my phone by pressing the power button the touchscreen becomes unresponsive. The side buttons both work but nothing happens as I tap the screen, I can't unlock it or shut down. Then, out of nowhere it starts to work briefly, and I can shutdown only, not unlock.
But this time it rebooted and remained unresponsive, I can input 2 of the pin numbers and then it goes unresponsive... RMA?
Thank you

This dont look like a problem before..... You seem to be the first one with this problem. Have you ever dropped your phone? Or installed something wierd? Can you also tell what you did before when this problem came?

The phone is imaculated, never droped it. The first signs were after I installed Swiftkey, the key to change between numbers and symbols was not responding. Now sometimes the screen is all unresponsive, other times the top bar can be accessed, other times the menu keys don't work. I did a factory reset, after much struggle to get to the Config. menu, rebooted to the same issue.

I wouldn't loose to much time, trying to hunt down the problem. Sounds like the digitizer is broken. Unless you use your phone only while connected to the charger. Most chargers will emit a low electrical field that makes it almost impossible to operate the touchscreen. If this is not the case, replace the device.

It's not connected to anything right now, the top bar and 3 menu buttons are working but the rest is dead, can't swipe the screen or select any app, not even the app drawer. I guess it's RMA time.

Yea seems like a good idea, its a great device. I hope your warranty is still working

No boot after update AW

Hi guys,
This morning when I woke up I jumped update android wear and I've given update (fully charged battery), it has been updated me and after the previous update all applications has shut down and no longer responds.
Neither wrist gestures or touch on the screen, or pressing the button several seconds ...
Not that the screen is left in black, but this off, because I either mobile is connected.
Any remedy?
Regards.

I have the exact same problem. No solution found as of yet.

ihave the same problem

I'm just waiting for me to answer the Amazon seller who I bought it. I have sent a request for reimbursement or replacement.

Have you tried to hold down the button for a good while? The watch should produce a long vibrate (keep the button pressed) and then after that should power off.

Yes, I have held down more than 30 seconds and does nothing...

Same here. After fiddling with things for a bit, I was able to discover that my watch was actually on, and connected to my phone, and I could see the watch's storage and battery, and even grab a screenshot from the wear app, but the display itself is completely dead after the OTA. Working brilliantly one moment (never any problems with this watch), OTA installs, and BAM, display dead. Digitizer even works, I can press and hold on the display and you feel the vibration that you normally would when selecting a new face.
I should point out that I was completely stock. No root, no third party recovery. The only thing that had been done was developer options had been enabled.
I ended up opening a case with LG and sent it off today for service. But clearly something was broken with this OTA to have this happen to multiple people.

I just spoke with LG SAT and tomorrow will come for him.
He also told me that as I have only one month and seems to be a failure of the clock, they will be responsible for repair or will send me a new one.
Anyway, it seems to me a big failure. I had the watch factory complements and after updating, it was fried.

Black Screen Of Death. Screen Goes Black And Persists Through Any Type Of Reboot

I have a Note 8 that i have never dropped, had this phone since release haven't rooted. However it is running one of the early Oreo Beta builds CQLB the phone is on Sprint. This has happened once before about 2 months ago and i can almost guarantee it happened in the same fashion as the most recent time a few days ago. It seems while receiving a call i go to reach in my pocket and hit several buttons pulling it out (because of the bulky case) then my screen goes completely black.
(This is where it starts to sound like the normal black screen issue that there are a thousand YouTube videos for)
The phone still makes noises for notifications, rings when calling and other noises like emails and low battery alarm. The screen however doesn't display anything whatsoever and has a blue led blinking.
(This is where it differs)
I've done every button combination i can think of with no avail.
-The regular restart button combination Vol Up + Power and hold for 7-10 secs,
-I've tried to boot into Recovery mode by guessing at what time the Samsung logo should be on the screen and pressing the vol button down several times
-I've tried to boot into safe mode by pressing the Bixby button, power and Vol Up and without the screen displaying anything i can of course not see if i was in Recovery or not.
The screen doesn't display a Samsung Logo, No sprint splash screen NOTHING. The last time this only lasted for about 3 hours and it suddenly came back up when being on the charger and restarted several times. This is now day 3 and after dozens of restarts nothing has worked, on or off the charger. I mentioned the Oreo build because maybe it's linked to that? i haven't had this issue on regular Nougat. ANY help is appreciated and thanks in advance

Try turning off Always on Display. It worked for me..
Actually your problem seems different, so doubt it will work

Kinda hard to do without anything displaying on the screen whatsoever, anyway i mailed it off yesterday for repair from Samsung. It was either that or a 2 hour drive to 12 Mile (Detroit) to bring it to the Ubreakifix store.
Unfortunately Sprint doesn't offer loner phones and can't activate any phone that is non sprint outside of some iPhones which sound a bit strange but now I'm out a phone for 9-11 days :silly:

Have you solved this issue? I have the same issue with my phone. It started happening to me even when I was on Nougat. Happens to me several times already. It goes black screen for about an hour to 3 hours then randomly get back to normal (get notification sounds, can receive call, etc). I am now on Oreo. Everything is stock. Never rooted my device as well.
Tried to bring to Samsung but all they did is 'Software Update' the device which is basically reinstalling the firmware and wipe everything. Service Center sucks and doesn't want to claim it is a defective unit.

My note 8 began experiencing this yesterday and after some frustrations and work around, I managed to pinpoint the issue.
Work around was go unlock phone and drag down taskbar, then click on systems and the system interface would open, after which I could press buttons on lower part of phone and clearscfeen to get back to homepage.
Problem was with Google. In my case I realised when I opened Google maps, the screen went black, so I went into applications and cleared the Google cache and Google maps cache. No 0roblems since.

Is it something with Snapdragon?
