I had to replace my FP scanner after damaging it during replacement of my digitizer screen (4 attempts and finally got the digitizer working properly!).
I purchased the new FP scanner ~$13US here:
Atrix FP reader
Things needed for replacement:
- Plastic pry tool or fingernail
- Two sided tape/adhesive
Steps:
Open the Atrix up as instructed for digitizer removal, until after the point of the chassis cover. Careful removing this cover, its how I broke my scanner when it got yanked during one of the removals.
Next with a fingernail or pry tool, lift the black ribbon cable lock from right to left so its opened up 90 degrees as in my picture.
Pull the old FP scanner out left to right.
Now you will need to remove the plastic backing from the old FP scanner (for the power button) to stick to the new FP scanner part using adhesive tape. Make sure its oriented the same way!
Insert the new FP scanner into the ribbon connector until the white line on the scanner lines up to the edge of the locking connector.
Close the black locking tab down (left to right) so it locks the new FP scanner cable into place.
Replace the chassis cover piece and install the battery and test if the FP scanner is working. Then reassemble after if working...

Hello guys
Tools Needed to separate digitizer
i got the digitizer from ebay,
hot air gun
exacto knife
i used IR thermometer to measure
double sided tape
first i thought removing the digitizer completely, and i experimented in old broken evo 3D digitizer to find out at what temp the glue between the glass and the plastic digitizer starts to lose(85-90degree Celsius)
after i found out that removing the glass pieces from the digitizer layer would be much easier,
my buddy helped me with the heat gun.
keep it moving don't stop at a spot it will damage the lcd,maintain temp between 85celcius(185F)to90celcius(194F)
using the knife remove the glass piece, remove one piece at a time.don't dig deeper when glass pieces are completely removed start heating at the top slowly peal of plastic digitizer layer from the lcd,
During this process maintain the temp at 85deg cel because dna lcd did't have the side metal support if the temp is low or you hurried means the top layer of the lcd will rip off .
after that i checked the lcd it worked no bleed or blackink
I cleaned the old glue and applied the double sided tape. the seller did't gave me pre cut tape so i have cut 2mm for sides and copied the old glue patter at the top and bottem . align the lcd use tape on the backside don't forget to peal of the soft key light diffuser from old one and transfer it to new one
i attached couple of photo taken doing this in a rar file
a pair of hands will be helpful and luck from Jesus .
Be careful with the knife i cut my fingers twice and glass pieces will fly around so wear glasses.
This is great news, however, I already destroyed my LCD in the process of finding that temperature. I was wondering if you could explain the pattern for the double sided tape. Does it not completely surround the opening around the LCD? Should there be a gap for the digitizer ribbon?

you need to make a slot for ribbon cable and holes for front camera and sensor.
Where did you get your double sided tape or could you recommend a source? Thanks

you can use 3m tape. i used nippon tape.

Hello,
I had a working Kindle fire HD 6 with a shattered screen. I replaced the screen glass and now my digitizer doesn't seem to work anymore. It doesn't respond to touches on most of the screen and the screen jumps around with no touching all. I've double checked all of the cables and connections and they all look good and secure. I've cleaned the connectors with alcohol, cleaned the glass and digitizer, made sure the plastic film was removed from the glass before installation, made sure the ribbon cables are fully inserted, and factory reset. I've disassembled everything and put it all back multiple times. Still same digitizer issues. Anything special needed to get the digitizer working after screen glass replacement. Thanks
So, I was wondering how to separate the fingerprint scanner from the camera glass module. I ordered different color (red) back cover with camera glass because mine broke, so i need only the fingerprint module to put under the new glass?
Any ideas will help me a lot.
What's the crack with the fingerprint reader? Is it compatible with screen protectors? Can't find any information about it at all.

I'm assuming it's the same FP reader as in the S10 and N10, which means it's compatible with your typical soft TPU or PET file screen protectors. I.e. Skinomi, Ringke Easy Film, etc... As far as tempered glass it would have to be a full adhesive protector.
For example on the curved screens of the N10, all the tempered glass screen protectors just have adhesive around the edges, so there's an air gap under the glass, which blocks the ultrasonic FP reader. Except Whitestone Dome, which attaches the glass with LOCA glue and is the only screen protector certified to work with the FP reader.
But since the S6 will have a flat screen, you should be able to find a TGSP that is full adhesive, which theoretically will not affect the FP sensor.

Allegedly it's not the ultrasonic fingerprint reader, that's the only info I have seen. If it's not that I'm not sure it is which is the problem.
As the tab S6 uses an optical fingerprint scanner (as apposed to the ultrasonic scanner in the S10/N10) it should work with any screen protector
Have applied a glass screen protector to the Tab S6. No issues whatsoever with the fingerprint sensor. The sensor is an optical one. In fact, the Tab S6 fingerprint reader feels quicker and more reliable than the one on the S10/S10+, even if not as secure.
(The Tab S6 has been available for purchase in Singapore stores since 24 Aug).
But i have problems with it now.
I cannot add new fingerprint.
The middle shows a very small green print. That should grow and grow, but it doesn't.
What am i doing wrong?
Restarted, quit all programs etc efc
First it did not read my old print. I cleaned it and now it is working. But a new one....
Look at the picture here. Only a small print in the middle.
https://photos.app.goo.gl/X9dykqErJRV2nNru6
I made a new topic... But solved... I had to push much harder
Still, sometimes, the Tab does not read any of my prints,but after a while it starts working
1. I want to enter the start screen with any of the three fingers, without success
2. I do a test in the fingerprints settings menu and no finger recognised
3. After a while it starts working, every time a little better/faster.
Seems a software problem
I've mainly been using face recognition, it's rapid.
I switched it off. Working terribly. Successful make of finger print, log maybe 3 4 times fast, then not entering at all.
I hope sw problem, I have tab with very first sw version, 1.jun dated, it even have tab s4 wallpapers not s6.
Hi there, my daughter's 2 weeks old Mi A3 with 3 fingerprints saved has started to be very inaccurate in detecting and unlocking the phone.
When the phone was just out of the box, the fp unlocking was 100% accurate.
Subsequently she had a tempered glass screen protector put on but after putting it on the fp was still accurate only started to give problem since last night.
Has anyone encounter this issue before?
I'm thinking it could be the screen protector but my daughter prefer having the screen protector and using face unlock instead of doing away with the screen protector.
Thanks
I have similar experience with tempered glass protector. I believe it's caused by additional refractive and reflective layer over the display. Under certain light conditions I almost couldn't unlock the phone with FP. Re-registering finerprints helped to some extent, but eventually I've just switched to soft TPU protector (called hydrogel these days). Not the same level of protection, but it's almost invisible and doesn't interfere with FP sensor.
I think it's software fail, the unlock is inaccurate, but if I use a third part app (like my bank app), the unlock Is fast and accurate.
I installed a tempered glass protector thingy last night. I deleted all my fingerprints, and rescanned them. Nothing. Didn't work.
The culprit? Ambient light (you know the one that turns your screen warmer for night time, that one).
I tried again this morning , scanned two fingers and it works like a charm .
Ah, yes. I had to disable Night Light. When it's on scanner is random
Since I removed glass protector, FP works fine also with Night light. With the extra glass layer it was more hit or miss. It was a cheapo protector with exposed edges, maybe with more expensive edge-to-edge ones it won't make such a difference.
Thanks for all the updates.
I have dialled down the intensity to slightly more than 1/2 of the scale and fp still working!!
I do prefer the nightlight function to reduce the level of blue light.
