Fingerprint sensor bug(?) - Huawei P10 Questions & Answers

So i recently got my screen on my p10 lite repaired, first thing i notice is that everytime phone is off for 5 mins, the fingerprint sensor doesnt work but when i open it using the pattern it works. Any clues on what's the problem?

yep that's strange
I had a similiar expirience with my P10, but without repairing it.
One day, I could only unlock it with my thumb, the other four fingers didn't work anymore.
Maybe it was my new (very salty) body lotion, dry fingers or some static charge on the phone? I rebooted the device after some hours and it worked fine again..

Delete the finger ids and register them back

[Q] How to change Proximity Sensor's settings on HD7?

I don't know what I did (maybe install something) but now my proximity sensor on my HD7 is out of whack. When I do a call it almost instantly goes to black even if it isn't next to my face or anything else. And it won't go back to the regular screen until after the call is over. (Yes I've tried pushign the button on the top of the phone). The phone has worked for months just fine, but a couple weeks ago I noticed this new behavior.
I've tried finding the right ## code to get to these settings but I can't find the one that works with the HD7.
I've tried calling T-Mobile support too, all they said is to hard reset my phone. Which I'd rather not do. Especially if it is a simple setting that can be adjusted.
Thanks
htc hd 7 proximity sensor problem
Hii, l have the same problem but l have not solve it yet.did you solve your problem? Can you help me about this topic.thanks...
I had it number of times in my case hardware issue.
To fix. Take battery out, clean the two sensors on top of screen left to htc logo. Clean properly with washing up liquid as water or finger did not work. Dry it up with phone off for about 1h and presto.
I always trigger the fault on hot day or rainy day.

Touch Screen unresponsive!

Has anyone had issues with their Z3 compact screen becoming unresponsive to touches? This happened to me last night even after hard shutdown via power button + volume up key.
My phone is encrypted so after restarting, I was stuck at the code unlock screen but the touch screen was completely unresponsive. After a few more hard shutdowns, a few hours off and alot of cursing, the touch screen finally started working again as if nothing was wrong.
Any ideas guys? I don't want to send this phone in if this was a one time thing, but I'm afraid it won't be the only time...
I guess I'm the only case of this happening?

It can occur for lots of reasons
This can be only software lag instead of touch panel problem.
and even 3rd party app can freeze your phone like this.
anyway the possible solution and way to understand if it s software or hardware problem is to repair firmware by PC companion
:good:

The reason I don't think its software related is because after the reboot my phone goes into the device encryption unlock menu right away. This menu theoretically should have little to no software loaded at this point, yet it still didn't response to touch. Now, I did recently downgrade from the latest UK ROM to the next available U.S. ROM. Not sure if that may have affected anything...
No more problems yet though...

Was the phone wet? Water can mess with the capacitive screen but shouldn't still be a factor after drying it with a rag. I'm assuming you realized this already, but doesn't hurt to double check.

Screen is not the issue… its the system

My Z3 do this too.. i dont know what to do
Same here. Happend 5 minutes ago and since no response from the phone -.-"
I hope it settles itself again.
Edit:
Now it works again. Strange behavior
I just returned my Z3c because of a touch screen malfunction. But in my case, it wasn't unresponsive, it just went nuts. It located taps at totally different spots from where I was touching, so typing, scrolling, etc. just was impossible. Luckily, this state only lasted for a couple of seconds up to a minute max, but occurred several times a day. Phone now exchanged for the "big" Z3 (due to arrive tomorrow), hope it hasn't the same issues.
I have found the reason my phone was unresponsive. I disabled some apps through adb, one of them seems to have caused the issue (dunno which though).
So I just restored the phone using the pc companion and since then no unresponsive touch screen.

Z3 Compact top half of touch screen not working
The top half of the screen of my Z3 Compact doesn't register any touches anymore. The bottom half is OK.
The phone wasn't dropped or anything. I did a repair with PC Companion and nothing, still the same....
Sigh!
hello, well the same thing is happened to me but my phon is z3 dual, this happened just before hour ago
Any solutions ..
I've just bought it about 2 weeks ago
I have the same problem, the touch is not responding and I can't use the phone since yesterday.
did reset by buttons and also by that yellow reset button and still nothing, it powers on but I am stuck when it asks me to enter the PIN code, because the touch is not working.
Anyone got a solution for that?
Which apps you have disabled on adb and say cause that issue?
Same trouble over here. Experimenting this unresponsive touch panel since today, several hours without working at all. I just blocked some boatware apps, but this should not affect touch panel, right?
Just restored the whole phone using official from Sony PC Companion software. It remains the same trouble with touch panel.
Today, in house, we put the phone under tap water just a blink. Do you think this could have damaged the device, though is water resistant? Do you know where are the humidity sensors, that could have change? Thank you for helping!

Unresponsive fingerprint sensor

Hey guys,
Recently, I've been having issues with my fingerprint sensor/unlock screen. Sometimes when I pull my phone out of my pocket and attempt to unlock the phone witht he fingerprint sensor, it won't respond. I then press the power button, which turns the screen on and when I use the fingerprint sensor, i can feel the vibration from the button but the screen does not unlock. There is also no fingerprint icon at the bottom. I can't unlock by swiping and putting in my password either. This eventually fixes itself after 30-45 seconds, but its really annoying when I want to use my phone. I've tried switching launchers, thinking that this might have been the problem, but this did not fix it.
I'm running stock OxygenOS 4.1.6, kernel [email protected] #1. I'm using the google launcher currently.
Its something to do with the light sensor cause i have it happen at night time when i am listening to podcasts in bed, it comes up to press one of the volume buttons and back to bypass it - but after 10 seconds it lets you unlock it anyway?
Pocket mode, try turning that off. Pocket mode uses the proximity sensor (I think) to detect whether it's in a pocket or not. If it is, then the fingerprint scanner will refuse to work so as to prevent accidental touches in the pocket
Turned it off last night. It's still happening. And it happens even when the phone is sitting on my desk. I go to try and unlock it and it won't respond.3
Delete and reset them. I find it happens after a month or so of use. I'm on Sultans marshmallow.
Originally when it happened I thought the ROM had gone bonkers and flashed back to stock. I missed the battery life too much on the CM13 build so I tried his marshmallow again. And guess what? It happed again. So I just deleted them and reset my fingerprints and voila! Snappy again.
Let me know if it works for you!
Just delete your current fingerprints and reset them. Should become snappy once again.
Happened to one of my friends and that's how I fixed it for him.
Cheers.
Never had issues with. Maybe you use it wrong side of finger, i mean you must unlock with you finger horizontally and not vertically finger

My phone has started acting wonky, not only with the finger print sensor but sometimes the touchscreen will become unresponsive, but I'll be able to turn the screen on or off. I'll have to try resetting tonight.

Screen dead

Hello
I have purchased a p30 pro recently. Yesterday, while using phone, suddenly the screen colors got washed out, then after some minutes the screen went full black. I believe touch is working, just the screen sometimes draw some subtle vertical lines and no image appears.
I'm not much concerned if the phone works or not in the future, but i have very important files in the phone that i need to retrieve and i believe if i send the phone to a service center it will be reseted.
Any suggestions of what i should do?
I've tried:
- Pressing the power button 20 seconds while phone is connected to tv whith an usb-c - hdmi adaptor. Huawei logo appears on tv but after that screen flickers with black. If i was able to have the pin screen there would've been great as could install an app to send fles to cloud after.
- Tried with the PC suite HiSuite, but since mobile is locked with pin, it cannot connect to do backup.
- Tried to insert the pin in "blind" by touching screen
Would appreciate if someone could help. Is there any way to enter the initial pin to have access to mobile, but without using screen?
Thanks
P.S. Phone didnt felt or anything, just subtedly washed on the faucet with just water as it was bit dirty (like 10 hours previous to failture). Wasnt submerged either. Will try to put it on a rice bowl eventually, but an IP68 phone (Pro) i find strange, i have done that several times on my old S8 and never had an issue.
Phones are NOT waterproof. Have seen several liquid damaged iPhones and Galaxy phones. Most likely the phone is liquid damaged. Second likelihood is damaged display. Rice will make it worse. You’ll need someone, a mobile phone repair technician, to open it up as soon as possible and remove the corrosion with IPA or an ultrasonic cleaner. The longer you wait, the worse the corrosive damage becomes. Look for a shop that's competent enough to remove the rear glass without cracking it. Franchises are generally less reliable.
You can use HiSuite to retrieve files or even preview the contents of ur display , thing is you have to find a way to press the accept button for the usb authorization when asked from the phone.
EDIT: Just saw you used the method but your phone is locked with a pin so i would suggest to try the blind method to unlock the phone.
Solved, thank you all
Was able to unlock and backup everything, was lucky

Fingerprint sensor

Hello everyone
I have p20 Pro and I live in Syria
My fingerprint broke a year ago and that's not my problem
A week ago suddenly my phone didn't ring
It shows the notification that I have a call and when I try to answer I can't like someone is touching the screen and when I put my finger on the finger print.. Every thing goes back to normal
And here no one knew how to change the fingerprint sensor or just disconnecting it
I just want a method I can disable the sensor
I don't want it anymore and no one is doing it for me in my country
So please if there is anyway I can disconnect it using some commands or something
Thank you sooo much
I heated the fingerprint on the front side of the phone and took it off
I cut the wire connecting it to thedevice
And now everything went back to normal
Modern problems require modern solutions ???
