Screen suddenly not Responding to any touch - Resolved - Huawei Mate 20 Pro Questions & Answers

Hi all,
I'm currently on holiday and my phone as many of us is my carry camera, sat nav and all around organizing tool!
Used it yesterday all day with no issues , got to the car and the camera was running. No big deal except the screen had become unresponsive, nothing would work so I did a volume down/power button to force restart.
That didn't help and i'm now where I was 15 hrs ago at the pin enter screen, I cannot factory restart as it wants you to type in Yes (omg) :laugh:
I cannot back up and data (all photos on a memory card though :good: )
Tried multiple restarts, shutdowns, run it flat, charged it up, done the restarts connected to a computer, not connected.
Could I factory reset via ADB?
Use a mouse to unlock?
Different combination of button presses?
Promise to be a better man..anything!:
Any idea very welcome!!
Thank you
Rory

Anyone? , using my spare old m8 and it is hard work compared to the Mate!

Send it to service centre..

What he said )

Any other suggestions apart from returning it?
Someone must have had a similar issue (well I know they have via searching but there hasn't been any advice on the next step.
It seems more like a software fault rather than hardware (or maybe that is wishful thinking) plus sending to Huawei doesn't really help while on holiday. ?
The phone has never been dropped, always in a case, etc..
Has or is it possible to factory reset it via adb only? I guess the other way is to update it via adb?
Calling all xda gurus, I know you are out there! any ideas welcome, apart from returning it at this stage. ?

As you said you can try using and external mouse!

Quick update.
Got it working.
USB wired mouse worked perfectly, this way you can back up all data, photos/android folder etc even if the phone does not come back to life. Kind of crucial as even if you have a memory card a NM reader is not easy to pick up (quickly)
Luckily with the bunch of cables i carry with my frequent travelling I was able to go wired usb A mouse to OTG to micro usb mini to mini to C adaptor. (obviously a micro usb C mouse is not as easy to get hold of)
Now the screen coming back to life process was not so clear, it took a few factory resets and a night plugged into a laptop in the bootloader menu to respond?
All was well for the last week of the holiday (however i fear a hardware problem may be hiding or I was unlucky with a software issue), either way all was good when it was needed and I will see what progresses.

Have the same issue, did the wired mouse let you use it for “regular” things like messaging

Sorry I cannot be more helpful as I never really did figure out why.
To repeat the post from last year:

Have you got a mouse plugged into usb C to back up and perform a factory reset??

Audio-Jack Issue

Hi All...
I was listening to some tunes on the Mozart today with my hands-free plugged into the device... and later when i tried playing audio songs over the speaker, it didn't output the sound.
To cut a long story short, even though i've plugged in and taken out the hands free numerous times, the phone still/always thinks that i have the hands free plugged in... thus no audio over speakers and i can't answer phones either without either plugging in the hands-free or turning on the speaker phone...
Any ideas on how to get this corrected?
Regards.
I have made an reset and solved the problem!

I soft-reset the phone multiple times without success... and finally did a a hard-reset, but the problem persists!
Frustrated!!!
Ok.... so here's it got fixed... FINALLY!
I was at the gym today and while working on a machine, the phone slid out of my pocket and fell onto the floor... And VOILA!!! It now works properly!
So if you ever run into this weird ****ty problem and have already tried putting in and taking out the handsfree/headset as well as soft-reset and hard reset... then just hold the device at waist length and let it fall onto the floor...
i'm guessing when you plug in the hand free, it actually push something down and doesn't come back up, that's why it keep on remains on hand free mode. Just my 2cent, probably a strip on the phone to see the hardware design.

That's my thought was... but i tried using a pin to touch every single pin i could find in the hole... but no luck with that.
Ever since i dropped the phone and it started working properly again, i haven't had this problem again...

A great way to solve a problem I will rembember that!
I solved this problem by using contact cleaner, just cleaned the headphone jack and all is working well!
This is definitely a hardware issue...
And how is banging Microsoft products will make them work? Do you mean the many, many software or their mice?

Xperia S bottom left side of the screen doesn't work if plugged in PC

Hello, guys.
I was swiping around with my phone today when I found out that to move an icon out of the dock became annoying. I thought it was just the phone got slow for so many apps running but even after a reboot it did the same.
It turns that if the phone is plugged in a PC (I've tried with two different PC's and two different O.S., Crunchbang and Windows 7) that part of the screen, about 3 squared centimeters, stops responding as it should. It doesn't hold a drag and drop swipe, for example. If you pull out the device from the PC, voilà, perfect. I tried with different official ROMs, installed wiping everything, even internal storage and always get the same problem.
I am using Android ICS (compilation 453 UK) and would appreciate your opinions, mainly to know if I am the only one with this issue, if this can be fixed or my phone will go right away to Sony in order to be fixed.
Thanks in advance!
P.S.: I'm rendering a video to show you clearly the issue...
Since you have tried anything on your hand to make it work, this might even be a dumb suggestion, but have you tried to plug the phone using another USB cable? Maybe it's the cable causing some sort of interference or something.
Thanks for your suggestion but I tried with two different cables. The original that comes with the phone and an HTC from my previous Nexus One.
This is really a weird and impossible to understand for me issue. I mean, I could understand if the phone gets a bit slower being connected to the PC due to the I/O operations of the Internal Storage or even more if it is connected in Debug mode but the fact just a 3 CM2 portion of the screen becomes iresponsive is getting me crazy.
Sony Tech Support just recommends me to send the phone back to them.
Turn it off for a while 3 hours let it chil.
Could do something.
Sent from a Galaxy far far away.
I just did what you said, left the phone switched off all night long and this morning switched on with the same results.
Anyway, thanks for your suggestion, it was really something I didn't think of before.

Strange keyboard behavior

I finally got around to buying a dock/keyboard and got mine today but I'm seeing some really strange things when using it.
I'm wondering if anybody has a clue what is happening to me.
Sometimes I connect the dock and they keyboard/mouse works perfectly. Other times, only the keyboard works. Sometimes, the mouse begins working after some time (like 30s); sometimes it doesn't work at all. Sometimes I connect the dock and neither the keyboard nor the mouse works.
I thought it may be a short in the connector, but I've seen things that suggest this is not the case. For example, I can press the lock key on the keyboard to lock the tablet, and then when I unlock the keyboard no longer works and its battery shows as empty. Other times, I can lock/unlock it with no problem at all.
I've tried wiggling the dock and stressing it in all directions to see if I can cause it to malfunction but once it works, it works forever until I either remove the dock or lock the tablet.
I normally use SwiftKey Tablet but switched to the asus keyboard hoping it would help, of course it didn't.
So are there any thoughts? wtf is going on with my brand new keyboard?
Also, fwiw, I know there is a mouse on/off key. That is not my problem.
Update: I cleared data on ASUS keyboard and it seems to have solved the problem. Not 100% sure yet but I haven't had any issues since.
I have the same issues. A reboot solves the problem. Factory reset solves the problem. Connecting the dock like 10 times solves the problem.
BUT.....
after a night of standby, the problems re-appear.
I've sent in my prime for RMA for this issues 2 times. 1st time they didn't do anything. Only re-connect some cable that apparently come loose on its own (****ty build quality)
I hope they fix is this time...
Unfortunately, clearing data on asus keyboard was an illusory solution. The problem came back.
I also noticed another issue. Sometimes when the keyboard seems to be functioning properly, it isn't actually charging the tablet. Talk about a weird issue. I noticed that when I'm having issues though, I can force kill the asus keyboard and redock and it works again until the tablet sleeps.
I did a factory reset on the thing, hoping it would help. Of course it didn't. To throw salt in the wounds, I didn't realize my app backup transfer failed so I lost everything. fml.
So anyway, the damn thing works probably 1/15 tries. It's so bad I packed the thing back up in the box and am considering returning it. The keyboards are so hard to find though I am not sure if I can get another.
Please let me know when you get it back from RMA. If they fix it for you I will send mine in.

umm...but the keyboard?
Also, my son dropped my prime and cracked the screen so I have to send it in for repair. I'm wondering if I should tell them about the keyboard issue while I'm at it.
You had the mobo on the tab replaced, right? Not the PCB in the keyboard?

Keyboard is working fine now.
The RMA only sais that they replaced the motherboard, not the keyboard pcb.
Wifi is working again, had to reset the router (even though all other devices were working fine).
Noticed a new LCD mura though.. so I'm sending it back again and claim my money back.

Continuous Issues with Gear VR apps rendering my phone useless

Aloha,
I have a Stock Verizon Samsung Galaxy S6 Edge. I was sitting on my couch watching tv when my phone lit up. I thought I got a message, picked it up and it said the charger connected is not genuine and charging was stopped to protect the phone (not the exact message). It was not plugged into anything. I ignored the screen. After a few minutes the screen activated again but was completely black with the exception of a tiny "x" in the bottom left corner of the screen. A voice came on and said to connect my Gear VR and install the Gear VR app. I do not own a Gear VR and until this issue did not know what it was. There was nothing I could do to get out of the screen. I tried to restart the phone and couldn't. Finally did a hard reboot. After booting up like normal it was only a minute before it did the same thing again. It renders the phone completely useless. I booted into safe mode and uninstalled everything related to Gear VR. There were no less than 3 apps that I did not install (I am assuming Samsung pushed them to the phone). It seemed to do the trick but the next day the apps were back and it did it again. I called Verizon, they had no idea what to do. They had me wipe the phone. It worked for a day before doing it again. I called Samsung and they had never heard of the issue. I can't find a thread here of anyone else with the issue either, however there are at least 50 people on YouTube that have commented on the following video with the same issue.
Here is a video of the issue (not me but someone else with the same issue)
https://www.youtube.com/watch?v=GtdahXCetu4
Here is the deal... Samsung was unable to help. They sent me a new phone under warranty. Its been 2 weeks and now the new one is doing the same thing!!!! I don't understand how this is so persistent an issue and no one on xda has posted on it. To make things more complicated when I had the first issue I was able to go into safe mode then application manager and uninstall the apps. Now they are appearing are no longer appearing under "installed" apps, it appears with the system apps and cannot be uninstalled. I have never experienced anything like this.
So there it is, I am hoping the genius of XDA can help where Samsung has failed. Thank you in advance for all the great work you guys do!

I was able to find a work around for the problem. I am not satisfied considering Samsung has offered no solution and taken no responsibility. However, if you boot into safe mode by holding the volume down and power button at the same time you can use your phone. Then go to play store and download Package Disabler Pro. This will allow you to disable the faulty Samsung Gear VR bloatware apps without rooting. It's a $2 band-aid but the solution worked for me. It has the added bonus of getting rid of all the other bloatware they load on the phone too. NFL app, I am looking at you! There was someone who said they cleaned the usb port and that worked. It didn't work for me though. So far no help from the XDA community, what's up with that?
I already install the app... thanks for the tip... but my USB port is not responding.... no charging, some times show me power sharing USB mode on... no OTG working... do you have and a idea of how to clean it?

Use isopropyl alcohol to clean your electronics. Typically a q-tip works fine but it will not get into the port so you need to find something that will get in there. You might be able to use a cloth dipped in the alcohol and something narrow like the blunt end of a needle to work it in the port. Don't go too crazy. Rubbing the alcohol along the contacts is usually sufficient. Unless you got something corrosive on the contacts. Good luck to you.
my s6 edge was having the same problem every time i plug the cable in the micro usb port, samsug gear vr pops out and next black screen with x. additional problem 1. not able to recognize by pc 2. disconnecting while charging 3. fast charging is not working 4. sometimes it take 4 hrs to charge.
having this problem for almost a month now tried everything from hard reset , cleaning the micro usb port and i dont wanna wait for 3 months without a phone for the warranty
fortunately i was able to fix it by my self yesterday. the problem was the flat metal in the middle of the micro usb port was pushed downward (screen facing up) so i just needed to lift it up a bit by using some flat tweezers (pls be careful) and everything works fine now.. solved all the problems i mentioned above
work 100%

Does the usb jig work for Samsung Galaxy Light?

Hi, I have a problem with my T399n.
My phone doesn't turn on, I installed CM12 and it was good, then I flashed the stock ROM from metro again, everything was good about a month, one day I made a call, whatsapp, text and then I put it in my pocket, then when I pulled it out like 10 minutes later and it was rebooting, I didn't pay attention to this because sometimes my phone reboots itself, later It was power off. I pulled the battery, reinserted it and nothing, connected usb cable, nothing, tried to charge it and nothing, Its like my phone died. Looking for a fix, there is the usb jig that work with others galaxy's.
So I just want to know if I'm fried or if there's a last hope to revive this phone with the usb jig
Thanks!
Something similar to this happened to me, would love to know the answer...
just today...
just today, not 2 hours ago at most I was playing around with my galaxy light, deciced to root and mod it.. first step was to, ofc flash a custom recovery... well like most things I pursue I ended up fighting the damn thing for HOURS!! could not get it to register on my computer for the life of me.. now I'm far from a dev and probably one of the least experienced on/around here but something so trivial as lack of drivers, udev, faulty port/cords isn't my forte.. so eventually I whipped out my handy dandy usb jig and .... nothing... *head scratch* hmmm.... now its got my attention... so I get out the multimeter usb data/charging cable and it does show signs of life, easily registering 5.1v / 0.4 mah ... now I'm getting anxious.... so its time for the next test... usb-otg connected to dbl usb-type-A converter to connect to the pooter (it never works but I wish it would ) and nothing there... so otg to my main mobile, reverse it... hmmm seems this lil guy is taking in charge and no data xfer of any kind... since id already rotated various cables I turned my attention to the charging port.. under 6x magnification and too many lumens light I could hardly see any problems but persisted with the 99% isopropyl anyhow... end result "wtf is wrong with this garbage....?) and just as I went to throw it at the wall I spotted my personal "boneyard" where all of my former problematic/faulty devices end up and just in sight was another tmobile galaxy light, broken lcd but logic board intact.. so a quick flip of the wrist and a smack on the back and the 2 became one... fired her up, plugged it in and BAM.. instantly detected... and for some reason I cant quite seem to put my finger on, I had the urge to power it back off and insert my usb jig one final time to see if it infact would work with the galaxy light.... *device in left hand... jib in the right.... bead of sweat steadily sliding down my ruffled brow... time seemed to all but come to a screeching halt as the two came closer until the moment of trust had arrived... the initial contact, the penetration (lol) .. the pause... BOOM factory mode*
so, now that u read that half illiterate rambling from a barely educated redneck shut-in to determine if the usb jig works with galaxy light or not .. the answer is yes... it does unless its a piece of crap like one of the 2 I own is...

It does in fact work. If asking about the USB mount, from my knowledge you would've had to already installed them by turning the function on like I did in the first screen shot.
If you need them I can link them to my drive or mega. Whichever is best. Think I have drop box still too.
And yes. I have bricked this phone I'm using now for a solid 3 days when I first started with it. However cm12 has bugs, after the second time it rebooted and bricked on me I went back to Tigerlily I even had no SIM error but somehow fixed that when flashed back to stock. Cm12 caused me to flash back to stock about 3 times a day. Too much headache. Guess thats why we are not supposed to do this to our primary phones. on tigerlily ive Had a little trouble keeping super su in his place too, Got home last night and POOF, just gone for no known reason. finally got him to stick by installing him into the system with lucky patcher. Flashify, flashfire, and even rom installer all failed to keep him there. . I have also stripped down almost every file just for fun to see what other fine items I could damage, Finally found where they hide the dialer codes for the phone. They are not in any files that i have spent the last for years looking in. The codes are inside of the APK. The last place I decided to look. Everything I know is self taught and just recently started working with apps for windows 10 and merging android files into windows apps.
Now , I'm actually quite impressed with it's capabilities .
Really what's helped me dial everything in was the helped of an app called Mixplorer with all the ad-on's all of which are free.
Good luck with your brick. Myself, I have 3 other phones I'm currently working on unbricking. One of which is a hard bricked LG motion. Flashed th err wrong firmware to it a year ago. Just this week got the cup to recognize it. the code to get into the first service menu pictured here on the bottom left is *#0808#
