Sudden black screen - Nubia Red Magic 5G / 5S Questions & Answers

Hi!
Today i was transferring some video clips from my Red Magic 5g to my laptop. Suddenly my sceen froze and turned black. I disconnected it from the USB cable but i still could hear the phone fan turning. The screen is still black and i have no idea on what to do. I haven't rooted my phone, i only use it to play and record gameplays for my YouTube channel. I hope you guys can have an idea on why this happened and how to fix it. Have a good day!

What happened? Hope you got to resolve the issue.
What I would have done in your place would have been to wait 20-30 minutes if it doesn't revert, press and hold power button till it force-restarts

try to put it to a charger or computer to determine if it hangs or it's status; or just do a hard reboot as Serdang just said and see!

[Q] Stock HOX - bricked by skype?

My phone is totally non-responsive. Pressing the power button is non-responsive, plugging it in to charge does not seem to work; no red charging LED. Won't boot while plugged in.
Here's what happened:
I set two alarms for this morning. One to wake up for a skype call I was supposed to make, and a second to actually get up. I hit snooze when the first alarm went off. I had about 50% battery according to the battery icon in the top right. I decided to make the call anyway and launched skype and started a video call. During the call the alarm went off again and I dismissed it. The video was frozen on the frame when the alarm went off. I backed out of the video on the skype app, and went back to it. The video was now black, and the phone warned me the camera was off. The camera icon in skype showed it was on, but i pressed it anyway, at which point the icon changed to the no-video icon. I selected front camera, the icon remained showing a camera with a red line through it. I still did not have video, my calling partner could not see me anymore either. We finished the call with audio only, about 15 minute total phone time. I pressed the top hardware button to shut off the screen and I went back to sleep waiting for the next alarm. That never came. I woke up and tried to turn on the screen with the hardware button and nothing happened. I believe I saw it flash a green LED notification as I was doing this too, but it never flashed again. I thought maybe I left skype open and the battery died, so I plugged it in. The phone won't start charging, or at least the LED wont show. I tried booting it after it was plugged in five minutes (still no LED) and nothing happens.
I unplugged it and tried holding power and down volume for 30 seconds, then I tried power and up volume, then I tried power and both down and up volume all for more than 30 seconds. No response. (what is the proper hard reset for this phone anyway?) I have since left in unplugged hoping that the battery will completely drain and then I can start using it.
Any ideas in the meantime? this phone will last a week with 50% without using the screen or the processor.

Does your hardware capacitive buttons flash when you press the power button for 10 secs?

No, nothing. I have a fully appreciation for the term "bricked" right now.
I think going back to the store is your best option in this case .... Unfortunately
yea, I think so too. I already emailed customer support.
If you plug the phone into a computer, go to device manager. Does it say QHSUSB_DLOAD anywhere?

So I went out all day and left my phone at home (the shop i bought the phone is on the ground floor of my office building an hour away, I was going to wait till monday to have it looked at there). Got back and plugged it in, was about to try usaff22's suggestion, but the LED started flashing red. after a bit it went solid and the phone turned right on. still no word from HTC, but it is the weekend and all. Maybe Jellybean will fix the root of the problem. Anyway, thanks for the suggestions everyone!

Broken Display?

ok so here is the rundown
Device: HTC one on vzw
Rom: Slimbean 2.x
Gapps: Slim AIO gapps
had a weird problem with the display today if anyone has had this or know someone who has i would greatly appreciate the help. I just flashed Slimbean 2.x last night and all was good. no problems what so ever, got everything setup and was working fine. this morning around 10am i opened snapchat to view a video. i clicked on the video and as soon as it started the screen went blank and would not turn on. i tried holding the power button down for at least a minute and nothing. also tried power and volume down, power and both volume buttons, power and volume up and still nothing seems to work. when i plug it into the wall charger the red LED light does not turn on and screen does not wake. when i plug it into the computer the computer does not ever read the device and noting pops up letting me browse the files on the phone. i have no clue why this happened it has been working fine for the 3 months that i've had it. took it to verizon about an hour ago and they didn't know either but they are sending me a replacement htc one. all i really want now are my photos that i have on the phone.
does anyone have any ideas about what i could do?
thanks
I had something similar and think it was conflict related. After installing the "advanced power menu" with xposed, I had an issue when trying to use it to boot into recovery. Basically it had timed out and then went away without rebooting. The next time I tried it locked up and my screen went black. My keys would light up if I clicked on the power button (it was dark in the room so the sensor was still working), but nothing else. Nothing I did would make the screen turn on at all and holding down the power key to reboot did not work. I just planned on letting the battery die out. After about 45 minutes, the phone just rebooted and everything was back to normal. I really think it locked up due to a conflict similar to what a PC might do.

Help: G3 doesn't power on - Only blue/green notification light blinks :(

The G3 just dropped down on the floor with the circle case. Then It was working some minutes apparently with no problem, until I myself turn the phone off and restart it. Then the device just didn't turn on. The only thing is that the screen is black and the led notification blinking green and blue
when i connect the charger, the red led blinks once and then disappears, then after 30 seconds the red led appears which apparently shows that the phone is charging the battery. Also When I connect the phone to the PC, a sound of connection is heard from PC but the PC doesn't complete the device recognition process as no new device is found.
I tried to make a hard reset, but nothing happens when I press the power and volume down keys. Tried some other tricks with the battery and the hard keys on the phone but no result at all, as the same story just repeats. Does anybody have a solution for the problem? This devise is the only android device I have
Help
Please Help :crying:

Did you do anything else after/during the time that the phone was off? And is there no possibility that you cracked the LCD digitizer? I mean it might sound strange but this is what I had with my old phone. I dropped it, nothing serious but then I put it in my pocket and upon taking it out I noticed the screen not turning on. As stated above, my digitizer was broken and multiple people told me that the digitizer had a small crack which I didn't notice, then when I put it in my pocket I put too much pressure on the digitizer cracking it. The LED-light did work though, and this sounds very similar so my advise going to the store and asking wether they know what the problem might be.
(Hopefully this was helpfull hehe)

If you Don't see the LG splash screen when pressing the power button it seems like a screen or digitizer problem for sure.
BUT;
after you try turning it "on" let it sit a few minutes and see if you can call your self or send a text to see if it makes noise vibrates etc. to confirm a screen problem.
OR
Also you can try putting it into download mode.
Battery pull (don't turn on)
plug USB into phone but not computer
Hold volume down AND then plug usb into computer
if this comes up to a pic of something on the phone it will be software related. to get out of this mode you can do a battery pull.
Remember to always read up on topics and things you are doing. There are guides here on XDA to help you out.
Hope you get your phone working

I didn't do anything special after/during the time the phone was off. I checked the screen very carefully under a lamp. No particular sign of crack. Thank you very much for sharing ur experience.:good:

Seems like the drop damaged the memory and the phone can't reload it, you will have to bring it in

Yeah that's plausible ! I'd bring it in too
Hope you fix your phone fast
Yeah... Probably it's a hardware problem. Someone who checked the phone in order to fix it, said that the problem had been with the device board. Even though I was satisfied with the phone, I have found out that the G3 is a sensitive device, as the height of the table from which it dropped down wasn't too much. So always take care of your G3 phone.

It didn't drop or hit by anything. i have been using it for 3 months now. it just happened by itself or may be by some update that I don’t know.
Please help how to bring it back to life

I tried several times.. nothing happens... any other suggestion please
Power+voldown+home.
If this does not boot, you could try with usb dongle.
Or full run down to empty battery.
Next chance would require to open it.

It's not bricked so calm down. It just had a cyber stroke. It will be fine just let the power run out and recharge the battery so u can turn it on again. Same thing happened within days for getting mine.
yes... I am waiting for the battery to be completely dead. so far its on...taking calls and sms..I don't howmuch % of batter is left cause I can't see it.
I had the exact same problem once....and i had a hunch that the screen was fine, it turned out it was thankfully....but....im aware that on 100 percent battery in standby it can last a good week or so....i was too impatient...so i ran my fingers around the edge of the backing and slowly was able to pull out the back of tge case and unclip the battery...worked straight away when turned on.
But also what i discovered does reset the tablet forcefully is holding power, vol down and the center button at the same time....try it a few times for a minute each time...if successful you might get a message about being in download mode but then just do the same thing again but imidiatly release your fingers once you see the screen go off from download mode or it will just go bavk into it...good luck m8
Have you tried holding down the power button for awhile, like 30 seconds? This should shut your device off....Then take it from there.

Seriously on my tab right now i just held vol down, power and center button whilst on and after 25 seconds screen went black then gave the "are you sure you want to enter download mode." Then i tapped vol up......t805 as well.
Battery completely empty.. tab S turned off, i plugged in the charging cable (1 ) battery meter does not appear (2) Power+vol does not work for me.. if it does.. i can't see because of the dead screen...
i have 2 options now..
(1) send it back in warranty.. this will take a lot of time and they will only fix not replace.. i guess
(2) open it and fix the display.

Hello,
Did you finally got some result?
I have exactly the same problem with a Samsung Galaxy Tab S 10.5. The screen suddenly went black although the light leds (home, back) were on.
I tried different combinations of buttons, usb charging and nothing. The only difference is that now the light leds are off.
---------- Post added at 08:46 PM ---------- Previous post was at 08:32 PM ----------
I have achieved to boot up the device because I have heard the start up sound and some notifications. However, the display doesn't work at all: the screen is black and there is no response when touching it. In addition, the light leds of the buttons are off now even when I push the home button.
Volume keys are working (I hear the sound then touching them).
Hard reset is VOLUME DOWN(left side on a 10.5) + POWER. Hold until it restarts.

But I can't figure how could this happen in a new (2 month) high-end product... I think that I will have to use the product warranty with the cost in time it involves.
This has happened to me twice during the last year. The last time was just ten minutes ago. I tried everything mentioned in this thread. VolUp+Home+Pwr for a looong time. Just PWR for a long time. I saw on my Wifi Router that the tablet was connected, but no screen. What helped me was to do a combination of everything mentioned here. What eventually got the screen on was 1. I turned of my router and 2. Home+VolDOWN+PWR for (what I believe was) 10-15 seconds. Then I got the choice to do a normal restart or a device reset. If you come this far, be sure to press VOL DN when asked. Otherwise your data will be lost. Obviously, I can't say if the router pwr off was necessary or not.
What's really weird is that my LG G3 went into a boot loop at about the same time (less than five minutes apart). They are not connected other than using the same router. I've had my LG G3 for exactly one year without ever experiencing a boot loop. The LG G3 is rooted, but my SM-T805 is not.

It's easy fix, most of the time due to loose LCD cable. If you can hear anything on the background but blank screen, 99% is loose cable.
Remove the back cover, disconnect and reconnect LCD cable, make sure it's fully inserted, then secure the connector with tapes. Test by plugin to charger, press the HOME button.
If you do correctly, the battery icon should show up on the screen. Then put back the cover, you're done.

Question Poco F3 suddenly dead

Hi guys,
today in the morning my Poco F3 seems to be suddenly dead...
I was communting and listening to Spotify as i heard a strange noise in my headsphones.
I pulled out the F3 and it seems to be restarting but it hung at the very beginning at the start where the Poco logo is shown.
It looked strange because the Poco logo had sone kind of red/orange glow arround and a little more down on the screen a multicolor stripe was shown.
So i long-pressed the powerbutton, the phone started again and it hung shortly at the Poco logo again and then directly shut down.
Since then there was no more sign of life....
When connectimg the Poco to a powerbank the LEDs of the powerbank appear but i don´t know if
this is not just because of the USB-connection.
Now i connected it for about an hour to a wallplug but nothing...
Is there anything i can do to bring it back to live or at least get to the data?

when you hold down the power button for a length of time can you feel/hear the vibration motor, try connecting to a PC and enter fastboot,
by pressing the Power and volume down buttons and release the power button after a few seconds and check to see if it is recognised.
I brought my F3 in the UK and it comes with 24 months warranty,
I hope you sort it.
Thanks for your reply.
But as i mentioned, theres absolutely nothing. I can press the powerbutton as long as i like, nothing.
Connecting the device to the PC also does simply nothing.
try another power adapter if still nothing hardware related probably motherboard
Were you charging your phone during your commute?
Something similar happened to me on a X3 NFC, nothing help. A year later I connected the phone to charger and everything is working now.
I assume it is out of warranty, if so remove the back disconnect the battery press the power button to drain any excess power, reconnect the battery plug the USB-C lead back in and hope you see life,
if not it looks like you need to get it professionally repaired,
