[Q] only digitizer works after 2 foot drop onto carpet.

Hello XDA,
So a Moto X 2014 was dropped from the height of a couch to a carpeted floor earlier today (my friends moto ). He picked it up, inspected it and then resumed using it after seeing no evidence of damage(no cracked screen). Next he turned the screen off. After a bit, when he went to turn the screen back on, it would not. The haptic feedback still works when hitting the home key and other parts. I can even drag up to get to google now, then start typing into the search bar. All of this is done by feel, without the screen being on at all. Also of course "ok google" works too. The phone also gives sound feedback. So now you guys get the picture here, only the screen does not work, and the digitizer does. I have two questions here:
1. How?
Why on earth would the phone still work until the screen was turned off?
2. Is there any way to fix this?
My hypothesis was that the display connector somehow became ajar due to the drop, which would require a teardown, which we will not do. Would a battery disconnect help at all. I think we may be willing to risk peeling off the back to disconnect the battery.
The phone is most likely going to to be returned, however if there is something we can do which might work possibly via software on the computer that would be great.
Thank you XDA so much for your help!

Enter boot loader. Turn off your phone and then press enter and volume down. After that with the volume down go to "factory" and press volume up to select it. Your phone will restart with out radio signal and a Commserver app on your status bar, there you can select the first option and check all the system hardware. Hope it helps.
Regards

I can't access the bootloader because the screen will not turn on. I would not know what I was selecting. That is the source of the problem. Thanks though.

Is there a way to do a factory reset over usb with adb? Also I cannot find the required drivers.... anyone out there?

Yeap. But first download minimal adb and Fastboot drivers then search for the firmware of your phone
The command is
Fastboot flash system system. img
I think you need to unlock your bootloader in order to flash even stock system files

Since you dropped it it is rarely possible that software is "broken" better to do is sending to motorola asking for warranty (if no signs of drop are visible) an hope.

Pocket dialing

Whats the best way you have found to prevent pocket dialing? Ive turned ambient display off and have to use a patern to unlock now. It the only way Ive been able to stop it. It works but I dont like not being able to use ambient display and I also dont like how long it take to open the phone with the pattern.
Any ideas?

Well, other than the obvious, don't put it in your pocket pattern, pin, password is the answer. Ambient display can be turned back on with a screen lock set. Or set screen lock to swipe. That might be a help. Or possibly a flip case.

Enable the Smart Lock feature under Settings->Security. Then set up a trusted Bluetooth device (wearable, etc.) paired with the phone to bypass the screen lock when in range. I use a Motorola Keylink on the key chain in my pocket.
Then, before putting the phone in your pocket, touch the Power button to turn off the screen. To turn it on again, while connected to your trusted Smart Lock device, you merely have to swipe the screen after touching the Power key.

even with a pin on my phone i sometimes pocket dial... only happened like 2 or 3 times in the 4 months ive had the phone. somehow it pulled up the emergency dialer.

I never add emergency contacts because this kept happening. No emergency contacts + some kind of lock is the best solution. I just write an emergency phone number to contact in the "Owner Info" in settings, so an emergency phone number shows up on the lock screen in case I ever lose my phone, and someone finds it and plans to return it.

i dont have emergency contacts either. what im saying is on my lock screen it brings up the dial pad and half the time its selected the emergency dialer at the bottom of the pin screen.

I'm guessing you have a pattern as your unlock method, so the emergency dialer is always at the bottom as soon as the screen turns on.
Try changing it to a PIN, so you have swipe up first, and then the emergency dialer/PIN screen come up.

no like i said i have a pin as my lock screen challenge. somehow the phone manages to swipe up the dialer or the unlock button and then pulls up the emergency dialer and start tapping numbers.

Same issue here, whether i have pattern or pin its still managed to unlock phone and pocket dial from the emergency dialler. I did have my pebble watch in smart unlock, this did all manner of things from video call the missus to change settings and force me to restore rom as i couldnt work out the issues.
I have a flip case that i really do not want to use as phone is big enough, ambient display on or off it still does it!

Problem with automatic reset after wrong pin entries (phone in front pocket)

I just got the P10 and like the phone in general but have a big problem with the phone resetting easily when carrying it in my front pants pocket. Our corporate device policy forces a reset after 10 wrong pin entries. This now happened 3x already and I am not 100% sure what I did wrong. I most probably put the phone back into my pocket with the screen still on (but locked) and assume that the screen then takes random inputs. I do have the option turned on to disable screen entry while the phone is in a pocket but this did nothing.
Anybody has an idea how to fix this ?

Bro, Are you saying your device was reformatted due to your corporate's device settings? (email maybe)?

Stuck in weird screen after factory reset

I factory reset my phone to wipe all personal data and make it as new again. But as soon as it turned on again, It displayed the Huawei logo as always, then the logo of my carrier, and then got stuck in this weird screen (see photo) where nothing i press or swipe will give any reaction.
Tried the hard reset by pressing up and down volume and power at the same time. A different screen appeared for a second mentioning EMUI and below Installing update 5% and then suddenly an error appeared (see second photo).
Please dear experts here, let me know what is going on... I love this phone and was very happy with it until I decided to the factory reset which on other phones always helped me get original performance back.
EDIT: well this forum wont let me post links as a new member, i guess that includes images. so let me try like this

hope that works

No idea why but it's showing the smart cover lock screen when its supposed to only show with a Huawei P9 smart cover that is closed on the screen.

oh so you're saying it's showing the screen as if there was a cover on it? that would make so much sense because i've had the display replaced just a day before... so maybe they didnt do it right and now the phone has some pressure on the LCD and thinks it's a cover?

Yes, exactly as you said, it is thinking the phone has a smart cover on it.
How the smart cover works is phones is that they have a magnet on the smart cover that where if you were to put a magnet at the exact spot on the screen it will trigger the hall effect sensor (The spot where the phone would be told that the smart cover is closed).
Yeah sounds like something went wrong with the screen replacement but it's rather rare for this to happen as it would require an magnet to trigger the smart cover sensor.

so weird... i hope they can fix that issue it's still not working but i will bring it back today. thanks for explaining how the smart cover works!
do you know by any chance on which part of the screen those triggers are? or that trigger magnet, if there's only one?

did you manage to resolve the issue? i currently have this problem

smart cover works with magnet. One of the quick fixes is to take a magnet and pass it over the screen. As i believe because im working for huawei they send us some devices and seems like the microphone or the speaker was moved. Those two have magnet and so it conflicts with the smart cover. Try as i said to pass a magnet from the screen and see if that would fix it. I am going to highlight That, This is happening due a hit, drop or misplaced speaker or microphone.

then you are going to have a factory repair because its either the mic or the speaker in a bad position and its activating the smart cover since both of them have a magnet in order to work.

Black screen and only Clock, date and weather

Hello,
My Huawei P20 Pro got stucked in a mode where displays black screen and only for about 40% of the screen, in the right it displays clock, date and weather. I can be called, the phone is charging but that's all. I had about ~70% battery when this happened. Reboot doesn't resolve the issue.
Any idea?
Thank you!

This sounds as if your P20 Pro is stuck in the mode for a closed flip case with a window (see https://i.ytimg.com/vi/G7sU3yGpRF8/maxresdefault.jpg).
That mode is normally triggered by a magnet located in the lid of the flip cover. Do you maybe happen to have a magnet too close to your P20 Pro?

Thanks
That was the issue. I just took off the case (which is not with flip) but it has a magnet for car. Thank you for your reply.

Go to settings -> Smart assistance and turn off Smart cover

hi, I have this issue. no flip case... n I can't into settings to turn off Smart Cover any ideas?

Anyone managed to fix this? I have the same issue. Tried everything, safe mode, recovery, restarting... I do not want to lose my data, is there a way that I can login and back up my data and then factory reset it? I cannot login because the screen is irresponsive and cant insert the pin for the screenlock, otherwise the screen itself works.

Dissconnect the Charging board

remove gently the back glass without damaging the finger print sensor flex and disconnect the main flex cable which goes from the second board to the main board, and start the phone without connecting the man flex, you will be able to go to settings and turn the slim cover option off

i have done almost everything talked about above on this phone for a week now but the black screen with date and battery percentage cant go off and the phone cant open anything else. its where it stops. what do i do . guys i need help i feel frustrated

Did anyone resolve this issue?I have same problem.however my screen did come back for 10-15 sec back and i manage to do hard reset but now i am stuck on black screen

Maybe too late, I was changing my battery already, then same thing happened to my p20 pro. I tried to use magnets to try unlock to no avail. Anyway read that the hall sensor is just at the upper left of the fingerptint sensor. After replacing the battery, turned it on, smart lock still active. Flipped it backwards, unscrewed the bottom right screws and gave it a few tap or knocks by hand an voila, screen is back to normal. I cant pinpoint the problem was, but thats how i fixed mine
