Fingerprint sensor doesn't work properly - Xiaomi Mi 9 Questions & Answers

Hey guys,
I have a slight problem. I registered my fingers to unlock my phone and sometimes someone else can unlock my phone using their fingerprints.
I guess that's not how this should work. Has someone experienced the same behaviour? I hope they can fix this with an upcoming update.

Did you try multiple people or just one person?

Weird... I tried but only registered fingers arw working.... Did you try to delete all registered fingers and add again? Or factory reset and try again?

Keyboard unresponsive

I am experiencing an unresponsive keyboard, at the bottom of the screen, after an hard reset. Previously it was working good without problems.
Any idea? does anyone had the same problem?
thanks
Reflash the rom your using. That solved the issue when I had it? Clean install it though.

What if I have the stock rom with S-ON?
Hmmm..... if a factory reset doesn't work. You could always unlock the boot loader and try a custom rom.
Or take it back to HTC etc if you still can ?

The problem is that the phone is not mine but a person found on internet owns the phone and I would buy it, now my question is: should I buy the phone even if it has this problem? the phone has 8 months and is still can send back to HTC.

It is a difficult question to ask. No one can tell what the problem is. It could be hardware or software. If you can get to the shell you can enter the command getevent and capture the output of the touch events. See if it is at least generating any touch events at that portion of the screen. If the tool is capturing any events you confirm that the hardware is working fine at the least.
Just change the kernel gouverneur to something other than powersafe/interactive or conservative and done.

Problem with HTC picking call

Hey guys I have a HTC one and due to its feather touch the phone call gets cancelled or connected in my pocket itself. Ian not sure what to do right now so any help would be great. I would like to pickup my phone without any problems. Thanks

How does the phone move about so much in your pocket that it gets to slide the Answer Call button?? You need new pants bro
I'm impressed of forum.xda-developers.com , I need to say. Really not often do I encounter a phorum that's each educative and entertaining, and let me inform you, you have got hit the nail on the head. Your concept is outstanding; the difficulty is one thing that not sufficient people are speaking intelligently about. I'm very blissful that I stumbled throughout this in my seek for something regarding this.
It's not sliding it's touch for some reason

Touching doesn't answer calls. To answer phone calls screen lock you have to drag the Answer Call button. So you probably have the screen on while in your pocket.
It's not drag for my HTC One don't know why would I require to lock with pass?

Nope, I don't have any lockscreens active. Mine is touch to answer only when the screen is on and unlocked, other wise I have to drag the Answer button to the middle to answer.
Don't know why even if i touch in the slightest it accepts call

You are certain that your homescreen is locked when you answer the call? Maybe record a video of you receiving a call?
Yup iam sure it's pretty irritating

I tried to change the touch and hold delay option to medium or even long, but nothing happen since this problem still made me crazy a lot. Does anyone else have the same problem with me that just tap anywhere on the screen to answer or end call in some case without slide the answer icon, I'm so crazy because most time I put my cell phone in the pocket.
I also had the problem but was fixed.

It will be my pleasure if you can show me how to fix this problem, I tried with some modification in accessibility option but nothing happened. I think that many other people have the same problem with me and be waiting for your help.
firstly in accessibility make it long touch and i then am using a cover.Other options could be rooting and going to a different rom but i would never root my device but,if u are into rooting then u could try it.

Yes I have that same problem and find it extremely annoying. Same with unlocking it..just the slightest touch on the screen anywhere and it unlocks. Might as well not have a lock screen if its that easy 2 unlock. I want to have to slide the lock icon up to unlock. For answer/decline call its just touch answer or touch decline, no sliding anything. Id prefer the sense 4.1 lock screen with the ring
EDIT: Has nothing to do with short/long touch. I found that turning off accessibility services solves the lock screen problem. Don't know about calls yet. Haven't tested that. Only the lock icon would move, now they all do as they should and just touching the screen doesn't unlock it anymore. Have to slide up to unlock as it's suppose to be

Thank for your quick reply. Firstly, I found that changing the touch delay option in accessibility become longer does not change anything.Secondly, I do not really want to you cover since I used the 1st cellphone until now. Therefore this problem is hard to fix until root my cellphobe. But the same with you, I think that I do not need to root my phone for this stupid reason. Just like you guys, I just hope HTC also quickly realize this problem soon and give some fix bugs in the next update. Anyway, thank for you help!

Hi, can you show me how to turn off the specific accessibility service which related to screen lock option? I looked for this option in accessibility but I did not find it. Thanks!

[Q] 4.4 Touchless control doesn't work when aux cable is plugged into phone

Title says it. It always worked no sweat on 4.2. Now whenever I have the headphone jack plugged in it doesn't register any voice commands or input at all. Kind of annoying if you use your phone while driving to listen to music. So my question is has anyone else noticed or can test theirs for me? Am I missing a toggle in the menus somewhere? It's really frustrating me.
- Nate
Saw this yesterday...Very frustrating as you said...This used to work in 4.2 right?
Yeah it definitely worked in the previous version.

Go in moto forums and tell them. That will be the fastest way to get fixed

Just a little update today....it started working again. Sort of. I basically have to yell at my phone to get it to recognize ok Google now. So it does work, but not at all like it did.

Strange, mines works as normal. Had a text conversation today with my buddy while dodging shi**y traffic and Lady Gaga blaring (don't ask) and it didn't miss a word.

I can't open that link (despite being registered with Moto too). Were you ever able to get it to work normally again?
I have the same problem on my new Moto X and haven't found a solution anywhere.

Note 3 help

Hello! I have a note 3 and in enough time my phone will boot then go to the at&t logo then just sit there for ~5~ min or even more...then sometimes will go back to the Samsung thing back to At&T logo and give it enough time and hard rest but it comes back and I have my phone again. Pain....in..my..ass
The solution: factory reset...but I hate doing this because I'm doing it repeatly now...
Has anyone else has this problem or have any advice for me?
Edit: Does anyone know anyone willing to trade a Note 3 AT&T for a SM-N9005? It has a glass screen protector and a aluminium home button.

What did you do to your phone? As in did you root it? Try to install a custom ROM? A custom recovery? Anything like that? You can odin back to stock from Root De La Vega from what I understand. I don't see anybody trading their phone for a broken one. You can't even trade here on XDA, you have to use Swappa or something else.
I added xposed and some apps the ones I am using are
Call recording
Gravity Box
Wanam
I can't install any custom Roms bootloader is still locked :/
So I fixed it by just factory resting everything. So my point on posting this is to see if anybody has this problem. The phone isn't broken it in perfect condition. I just don't know how much longer I can take without an unlocked bootloader.
If you wanted I could screenshot of what apps are using root?

Try taking your SD card out and then see if you still have the long boot or loop issue. Some phones are having issue reading certain brand SD cards and it id causing long boots or other strange problems..
Interesting....how old school lol
I'll try that

Just curious what (security hacks & advance mods) settings did you use in wanan?
when you got your note 3...You didnt carry over your sd card with anything on it did you from prior device? Or use titanium backup?
Id try to trouble shoot it this way...Disable wanan...reboot see If it does it again....If so, start with the other app and disable or unistall.....Keep trying you'll find the source
Gravity Box is not to be used with Note 3 ROM. I know things work with it but the OP says not to use on TouchWiz roms. Or I might be wrong..

I had the same issue I guess it coz of Gravity Box, it is advised not to use Gravity Box on Note 3 Touch Wiz I removed it and never faced the Boot Loop or System UI Stopped working since then.

Hard press or light tap home button

Hi guys,
I'd like to know whether you need to hard press the home/fingerprint button to go to home screen (while unlocked) or you can do it by a light tap.. coming from Xiaomi Mi5 and so used to this feature it would be a deal breaker for me if I had to hard press the button every time
Thanks
Sent from my MI 5 using Tapatalk
Light touch is fine. It's a touch button and not mechanical
Hope that helps

Thanks for the answer!
Btw by 'it's a touch button' it means that even when unlocking the phone it's light touched and not pressed?
That's nice!
Yes that's right. Just touch to unlock without PIN etc, once finger print has been set up. The first time after phone has been restarted it asks for PIN, but normally a simple touch is all you require

Yep I know the procedure and all, but on my Mi 5 you need to press the button to unlock and read the fingerprint. There is a sysfs trick to make it read with a light touch but the button is mechanical by default.
Thanks a lot mate, I'm not even bothered by the fact that the Nokia 8 is not (yet) unlockable so I'm probably getting it. I found a deal of around 300 EUR for a new device so it's a great price for a SD 835 phone.
