Hey all, I recently purchased a used Mi Mix 3 online. Unfortunately once I plugged it in and charged it I found that the screen of the phone does not work. It's simply black.
The phone itself works as I can hear the wake up sounds as well as the sounds when you open the camera.
What's going on here? Is the screen itself toast or is it the operating system? What options do I have here to get it working again? I did some research and I found that it could be an issue with the global firmware, but I have no way of accessing the phone to unlock the bootloader or enable USB debugging.
Any help here is much appreciated.
If its possible, sent back to the seller. If not, then there is nothing to do except asking xiaomi. they will probably say: contact the seller.

When you charged the phone did you see anything on the screen? Charging animation ?

Absolutely nothing. I'm starting to think it's just the screen, some users report touch functions working but mine do not.

Hi,
I'm not sure if there already is a thread about this problem, so sorry if there is
When I grabbed my Nexus 5 out my pocket, the screen didn´t work. It only shows pixels. I´ve tried to reset it to factory settings using a hard reset but that doesn´t work. It still only shows the pixels. I can´t send it back to LG for repair because I´ve changed the kernel and I can´t get a connection with my pc. Does anybody have any idea how to fix it?
Thanks in advance!
What do you mean by "can only see pixels" ?? Blurry lines?? Distortion?? If so, there's a possibility that the flex cable might have gone bad.. In any case, you need to send it in for repairs.

Yes I can only see blurry lines in different colours. But is it possible to repair it by replacing the screen + touch module?

May be, May be not. No one can know the extent of the damage without opening up the device.
You need professional help. So, it's either Google (if you've bought from play) or LG. There's nothing you can do here as the screen is completely useless. Just send it in and hope for the best.
If you want to backup your data, you could boot up the phone (if you can) and use adb to backup if you've enabled usb debugging. But that's about it..
Good luck!

Nexus 5 showing only pixels
Hi
Even I am facing the same issue. My nexus 5 is only 4 months old and from the past few days, display is not working consistently. It only shows pixels all over the screen and there is no image at all. Also, there is no physical damage to the phone at all. Although It just fell once recently on its back from a chairs height but it already had a strong spigen slim armor case that provides pretty good protection so i dont think that fall could have caused any internal damage.
A few days after this and after i upgraded to 5.1, I first started to see the screen hanging and then suddenly when i tried to restart, it started showing pixels all over the screen. A few times when i press power button multiple times, then sometimes (say 1 out of 20 times or even less) ,home screen appears but even then it does not work. I am very frustrated with the problem and not sure what could be the issue. Could you please let me know what could be the problem. I have shown it to some repair shops but it looks like they are just looking to grab money and they simply tell me that they can replace display.
So i thought its better to post it here in xda to get feedback on this. Please can you let me know what could be problem, is it hardware or software issue and how it could be resolved. Please help me urgently as I am not able to use the phone.
Thanks.
Hi, the other day while I was using my OPO as a GPS unit in the car, it seemed to freeze and restart, but it didn't boot. I thought it was just an empty battery problem. But since then, I haven't been able to use my phone again.
Apparently, it boots correctly, but I can't see anything on the screen. I say it boots correctly because I can hear the notifications, the led blinks, and I can even feel the feedback if I touch the capacitive buttons. Also I was able to backup my data through adb. But the screen is completely black. The only moment where it shows something is at the moment of booting, where the cyanogen logo should be, but it's completely scrambled (see attachment)...
I tried going back to stock (with the help of Bacon Root Toolkit) with no luck.
Has anyone faced the same problem? Do you think it might be a software problem? Otherwise, do you think it's a screen problem that I can fix changing the screen? Or it might be a problem with the GPU and changing the screen will not accomplish anything?
Thanks in advance for your help.
Cheers,
Capelare.
PS: Well, apparently I can't post the image since I just registered. It's here anyway: i_imgur_com/V9oH2el.jpg Just change the _ for dots, please. I'm sorry for the inconvenience.

Nobody knows what might be the problem?
Reflashing didn't help anything? Even with wiping all data?
Then i think its an hardware- based problem.

Try booting into fastboot (volume up and power when off) you will hear a vibration and fastboot mode should come up, if this doesn't happen, it's pretty much a dead giveaway that the hardware is broken

Thank you! Nothing happens with any of those methods. So yeah, I also suspected that it's a hardware problem... But do you know if I can figure out if it's the screen or the graphics system (I don't know how to call it other than graphic card... and it's not a card lol) before purchasing a screen replacement... Any ideas?
Thanks again,

I find it hard to believe that the gpu is broken, the cpu, gpu and more are all on a single chip and I don't think one part can just fail without the others failing too... but you never know, if you can still send it to oneplus for warranty do it, it saves you a lot of time. If you can't there are a few things you can do:
1. If you had usb debugging enabled and authorized to your pc, you can try to use some screen mirroring software on your pc that works via usb.
2. Contact a repair shop that will allow you to test a new or used display with your current phone.
3. Try connecting your one to a tv by using a micro usb to hdmi cable (DON'T KNOW IF THE ONE SUPPORTS THIS!!).
Good luck!

Thanks, I can't send it to oneplus because this screen is already a replacement and I changed it myself. I will try asking for another display
I didn't know the gpu and the cpu were on the same chip, but I also think it's not likely that one would fail and not the other.

So my Nexus 5 (a couple months ago) has started to just randomly go black. I get notifications and stuff, and the backlight but no display. Not sure what to do or what part to replace. Would flashing/rooting help at all?
Appears to be a hardware problem.
Was the phone every dropped or exposed to water/moisture? Possible loose connection inside?
No way to tell for sure if the phone needs a new screen unless you are able to test the motherboard in another N5.

It's been dropped a couple times but not like any major drops or anything. Im pretty sure I checked all the connections inside and they were good. Im starting to figure out that the phone has to be off for a little bit then I have to charge it and turn it on and it works again
Sounds like it could be a damaged lcd or lcd connection. If it can work after being charged while powered off, could be battery or USB flex cable issue.

Ya I figured out I have to reboot it a bunch of times then it will work
I think it might be the battery because this is my dad's old phone so it's been in use for a solid 3 years.. I wish I knew for sure though
So I have discovered that if my screen is on for a while the task bar at the bottom starts to shift up and down
Have you found out more about this? I think I have the same problem. My phone never turns black while I use it. But when the screen is off/sleeping, it sometimes won't turn on again. So a force reboot fixes it. Sometimes this happens a lot, some times it works fine a whole day.

Maybe, I don't think so. My phone was useless, black screen on every screen unlock. But namelessrom took that away, so that tip about nameless was for those who have the same black screen I had earlier. But now I have the same black screens as you do. Anyway, if you want to try it out, nameless-rom.org

Happens with my nexus too. The screen goes blank randomly ..... But i have managed to deal with it.
Its happan to me also, with 4 nexus 5 of my family.
Is a firmware problem?
I'm trying to buy a new flex cable to see if it will help I'll update when I find out
You're replacing the USB charging flex cable? If you are, be careful with cheap third-party replacements as I have read reports of people having issues with charging, signal, or speaker functionality after installing the cable.

Ya so i sent it to LG finally and the diagnostic said that it was a flex cable issue which I was sure that it was anyway but I have a confirmation now
I've had a similar problem when my display suddenly started failing. First, there was colourful bands over the working display, then colourful static only and then black with backlight only. Bought a new phone, left it for a year and today after digging in the phone for a while I found a fix. The connection between the motherboard (the top bit) and the daughter board (the bit below battery with USB and connection to display) was somewhat loose and when pressed on, the display worked beautifully. I stuffed the insides with some tape to maintain pressure on the connection and phone works great.
Might not work for your problem, but it's worth a try if you're out of warranty and have tools to disassemble the phone.
Hi,
Sorry if this is the wrong place, but my Pixel was working fine last night but suddenly the screen won't come on. The phone itself however works as I can use the fingerprint reader and I can feel it vibrate etc. (note that I've rebooted, so I can't get in without a pin.)
Anyone else had this, or any ideas why? I've just bought this phone as well

Hello, yesterday I received my phone. For the first hour it was working fine. But later, when I locked the phone I couldn't enter my password or shut down because phone started touching random things by itself. Did a factory reset but after that I can't even setup the phone because it doing random things by itself. Tried to discharge the phone and leave it overnight. But the next day it was the same story. I even peeled of screen protector but no luck. I think it's not system related issue, might be that I got the faulty one with bad touchscreen? Has anyone had this issue?
Mine doesn't has any touch issues. Seems a manufacturing defect, better off exchanging/returning it.

The problem is that I bought it overseas and returning it back would take very long because of the corona I"m wondering what's the problem could be, touchscreen or something more serious like motherboard. If it only screen I might change it by myself
Return it under warranty. The second you open it that is gone and if the problem persists, then you are screwed...
Not only have you lost the purchase price of the phone but the cost of the replacement screen too which generally aren't cheap...

Yeah, I get it. Also, Xiaomi have international warranty or only local? Because would be great if it could be changed at my country. But as far as I know it has just local warranty from where it was bought or am I wrong?

Idk, just randomly. I was using it for about an hour. Locked the phone for about 5min. And after that I couldn't enter my pin and read fingerprint because phone started randomly touching screen. I can't even shut down the phone screen is always on until battery discharges.

from where is your phone region? it can happen from many possibilities. maybe from the kernel. You can try to flash using miflash according to the firmware region.
or try to enter stock recovery, is it random touch or not. (vol + & power)
new phone is still a warranty, it's good to go to a xiaomi service center
My case was, when the phone was brand new power button was stucked . But after using it few times, everything was fine. It didn't happen again

In my case it was faulty digitizer, after replacament everything is fine. I bought it overseas so no international warranty, but seller refunded me half the price. I went for the screen replacment and after that everything works fine.
