So I droped the phone into water. And you should always turn off the device and let it dry. The problem was that the phone turned on and off itself. 2 days later when I have let it dry, I can start the phone. There is a bit of misscoloring on the screen. But when I try to enter my password, it doesn't recognize my finger. One time the screen changed like it was recognising a finger but that was only for a split second. Do you think the chip is dead? Can I remote control it somehow? I have rooted and have twrp installed. Thanks for answers
From what you say, it's damaged from water, one thing you can do is to buy a replacement for the FP sensor.
Still, wait a couple of days, it may begin to work properly again.

eBay, or something. Just type honor 8 fingerprint sensor. Buy you must teardown your phone like that.

There are many websites, like the one mentioned in the previous post.
However, I advise you to take to a repairman to replace it (if you don't have experience with this sort of things)

It's my bad, when you said the chip and finger in the same sentence, I didn't see the screen part.

After getting throught this problem http://forum.xda-developers.com/showthread.php?t=1644971 I got another one. My device felt down and now I got a small "slot" bbetween the display and the chassis. But thats not the only problem. The touchscreen (digitizer ??) does not work well. The four "onscreen" buttons dont work and about a quarter inch above them the screen doenst react well, sometimes it does, most of the tim not. I want to repair it by myself but I do not know much about it. I know how to assemble and disassmble, but thats it. Is this http://www.ebay.de/itm/270933343810 the part I have to change? Or is there even more or an other part?
Thank you so much guys!
I disassemled the hole thing now and I can see that there's a mini-crack in the lcd at the top right. No matter for the display at the moment. It must be the digitizer?! Is it possible that it is broken, while I cannot see a damage onit?

this is the part you need http://www.ebay.de/itm/LCD-Display-...75910021?pt=Handy_Zubehör&hash=item337330cc85
thats the whole assembly otherwise you will find it really hard because the touch screen digitizer and the main screen are together attatched.
Yesss baby! I replaced the digitzer and it works fine again.

Hey
few days ago my HOX ATT fall down. all the buttons were ok but after some days they had stopped working. i have tried to do factory reset but it didnt helped. all the touch screen works but the buttons not. i sent the HOX to Repair shop and they told me they have not seen thing like this before that only part of the touch digitizer working.
can you help me solve the problem?
Thanks.
The fact that the repair shop has never seen it before, does that mean they won't even try to fix it?
He said that he need to order this part to fix it and he even not sure that it will work.
is this hardware problem?

Since you dropped the phone recently, I'd be inclined to say yes.
I'd try to RUU, and if the problem persists, its probably a hardware failure caused by the drop.

You must buy the entire LCD - Digitizer -light guides bundle . It's almost impossible to separe the screen from the LCD, so buying the digitizer is a waste of time if you dont have the LCD.

the same thing for me, i have tryed everithing and not fixed yet, in a few weeks you will see how other parts in the touch screen will not work too.
As javierarenas has said, Purchasing the digitizer alone is a bad idea. Nearly impossible is an understatement. even with a heat gun and an unlimited amount of patience you would be lucky to separate the digitizer from the LCD.
As Redpoint said, if RUU doesn't fix it, you will need a new screen.
Take the phone apart prior to buying the screen. Check the colors of the ribbon cable and try to find the EXACT same screen. This will save you a lot of trouble. Make sure to keep the old screen in case you need to sync the new screen otherwise you are totally screwed.
Good luck.

Funny thing is I never had to take mine apart. But did have to reattach the screen, sat down with phone in back pocket and when I pulled it out it had separated the screen from body and had to use some iPhone screen double sided tape to glue back down.

Just noticed that my phone unlocks itself by scanning my irises even if I have my sun glasses on???
Maybe the scanner is too powerful I thought...so I covered one of the lenses with my hand...and tried unlocking it again...
And it did...it unlocked by scanning just one side of my face and with sun glasses on...
Maybe it is time to go back to the pin option.

Why? Matching just one iris is secure enough--and certainly more secure than a short PIN.
Yea just like the note 7 it works very well and fast
I haven't seen any real review of the fingerprint sensor - only comments about the position on the screen.
Since there is no face or iris detection like on the Note 9, the fingerprint sensor will have to be pretty good.
Any ideas about this?
Edit: I just found one review that says there is face detection, which is a relief if it's true. I definitely saw one report that said there was only the fingerprint, so I'm now hoping that was wrong.. https://www.youtube.com/watch?v=wlMMXKKyfu4

Well i hope they have improved the under screen scanner from the S10 plus because it was garbage. I actually sold my s10 plus because it was so unreliable.
There is face unlock but if it works like the s10 plus it is not secure and can be spoofed with a picture of yourself. I didnt use that feature due to this on the S10 plus and since the fingerprint scanner was trash ended up using a pin/pattern.
I didnt spend $1500 on a 2019 device to use old unlock tech lim
Iike like that.
They should have brought back the retina scanner to secure the face unlock
About 11:30 in you'll see the fingerprint sensor test. Appears flawless according to Unbox Therapy. Most people who had issues with the S10 fingerprint sensor had those issues due to the screen protectors they were using, even though they blame the phone.

I was using the factory installed screen protector on my S10 plus and the scanner was still terribly unreliable.
And Lew was not unlocking from a black screen in that video either which made a big difference on my s10 plus.
If i hit the power button to view the lock screen then unlocked it was more reliable but from a locked black screen it was less than 50% reliable.

I still think it had something to do with the Samsung screen protectors too, even though they claimed they were designed for that purpose. I do not use a screen protector at all. If anything happens to my screen it costs me 29 bucks to get a new one so I generally don't have any sensitivity issues.

Ah, gotcha'. When I look at that, though, I also add in the $13 a month for a total cost of $341 over 2 years, including one screen replacement. Not saying it's a ripoff or anything. I have used my insurance and was glad to have it. I just like to look at the total cost.
Many thanks for the link to that review, it puts my mind at rest.
I don't use screen protectors because I always use use a folding case - never broken a screen yet.

I totally agree! I even think note 9 was hands down the best true note phone the made.
The ultrasonic FP sensor is not an improved one or 2nd gen. or something, it's the same one used in the s10 series, now placed up.

Yes, I agree with you. I went from a nexus with it in the back as well, then the moto fingerprint reader at the base in the front to the back, and now it's going to the front again. I'm 80% sure I've disliked each transition but thelis iteration makes me the most nervous. The only thing I like about Apple is the Face ID as it's very quick. Though I don't like having my phone unlocked each time I pull it out. Plus, my work has strict security rules for keeping locked.

Well thats not good because it sucked on the S10 plus and is the main reason i got rid of it.
I could have a very short stay on the Note 10 plus if it is as bad....unfortunate since its an amazing device but being able to reliably and consistently unlock your device on the 1st attempt is a basic feature.

Yes, in order for me to have work email on my phone, corporate security policy requires using a pin with 7 numbers/letters and not just 4, or using a fingerprint reader, but no face unlock. Fun stuff.
Nexus had such a great fp reader! Was pretty responsive and the same place as the note 9. Will need to get used to maybe using my thumb now?

I would contact Poco or Xiaomi via their website for this. I'm sure it'll be under warranty if you didn't intentionally break it, considering how new the phone is.

Yep, this is the way to go. Use your warranty, by the look of things I'd say there might be a short circuit somewhere inside.
Return the phone to the place where you have purchased it. Instead of getting the single component replaced, just file for a replacement.
Unfortunately I am in the same situation, fingerprint stopped working after a fall and I had to open the phone and unplug the flex cable (goodbye warranty), impossible to find a replacement part as for now, I looked everywhere

Look at the attacched picture, don't mind the red circle, focus on the green one, that's the flex for fingerprint, to access it you have to:
1) remove plastic back cover
2) remove motherboard and camera's cover
If in the future you want to replace the fingerprint sensor it's not hard, I removed it to check the flex cable integrity so I can tell it's easy
WARNING: the motherboard cover screws have seals so if you remove them warranty is gone!

The power button uses a different flex cable which is not shown in the picture, don't worry, removing the flex i mentioned will only disable fingerprint scanner, power button will still work as usual
I compared Redmi Note 9 Pro and X3 NFC, fingerprint sensor looks identical (connector, cable and button looks the same) Im going to order sensor from 9 Pro and install it on X3 NFC and will report back if it works. Hopefully it does...

Interesting, thanks for reporting!
Codes on the flex cable are not identical but are really similar, anyway i tried to order it too (ordered it 2 weeks ago on aliexpress), as soon as i receive it, i will report back.
F3626WL is written on both X3 and 9 Pro
RA1 xxxxxxx is different, that's probably serial number or something like that, so its probably dfferent on every cable. Report if it works if you get it earlier than me.

Bought from same seller, ordered blue button, I think it will look neater instead of black.
Well, dropped the phone in water, been in water for 15+ minutes. Had to disassemble it immediately and dry it out. While removing back housing, I damaged the cable...Should've been more careful...
Everything major was completely dry lol, but water got inside screen backlight so there were bunch of marks on screen, luckily after drying it out, there are no marks...Even if this phone is just water resistant, it survived fine in bucket of water for 15 minutes.
Thanks everyone for sharing your experiences, I'm still stuck with the fingerprint broken, and I'll wait @marko.dnb and @fonz93 to reply, so I can buy the Redmi Note 9 Pro sensor.
