Strange bug with fingerprint scanner - Xiaomi Redmi Note 3 Questions & Answers

So I bought XRN3 (Snapdragon) 2 days ago and loving it! There is insignificant bug with fingerprint scanner. So I scanned my index fingers and am using it. I scanned them in natural position (meaning placing finger with nail facing up to the 3.5mm jack and IR blaster). If I scan my finger by turning it 180 degree, phone still unlocks but locks right away, which means it works, but locks again for some reason. Same for other index finger. It doesn't happen all the time through, sometimes it just unlocks. Anyone having these too?
I'm on MIUI 8.1.1.0 Global Stable.

Maybe you are blocking proximity sensor.

Go to lock screen and fingerprint setting the turn of all the features listed at the bottom that should help

Thanks! Tried. Doesn't helped I noticed that on MIUI7 there was less fingerprint reading errors. Tried to rewrite fingeprints settings several times. Don't know. But that doesn't bother me a lot.

Honor 9 Home Button delay

Hello , i own Honor 9 for 3 days and its very good phone.
Only thing that i "hate" is when i press home button there is like 0.5 sec. delay before it goes to main screen...
I tried Factory reset,phone restart,google assist turned off - nothing seems to work
Finger print scanner works fast. No problem with it.
FW: B150
Any ideas how to fix it?
Thanks
That because a simple touch is like previous. And if you hold for a second you go directly to main page. So it's normal
Mine has the same. Strange thing is that after a few hours usage it turns fast/instant all of a sudden. Then if I reboot it's back to the delay and then fast again after a little time. My first unit did not have this behaviour it was fast at all times. It had a faster fingerprint reader too. Not sure what is going on other than some kind of hardware differences.
Its normal don't worry about that.I too had a donor phone so I know this
That is strange as the Honor 9 has one of the best fingerprint scanners on the market.

Even past Huawei and Honor fingerprint scanners were much faster than those used in other android OEMs.

That's definitely not normal. I've made a video https://youtu.be/DG4PvJePUAY
You can see a noticeable difference on the left phone.
I'm returning mine as this seems like hardware defect to me.
I have the same problem. Is it really an hardware problem and it is not possible to fix it by software?
Same here. Sometimes it even stops working, but rebooting brings it back (to delayed mode). Unlocking with fingerprint scanner always works super fast though. Anyone else with the same issue?
I got my AL10 version from china some days ago and i dont have any delay issues with the home button. Its really fast without any delay.
Maybe the ones from you that got problems should write down their version and used firmware. So we can compare. I dont think that this is a hardware issue.
I just assumed it was a hardware issue as it stayed even though I did a factory reset. Maybe a future update fixes it but I wouldn't risk it because my phone was new and I wanted one that was all good.
Settings
You can just go to the developer settings and tick "animation time" to 0,5

Maybe it's an issue with the update running on your phone.
just bought honor 9 and I have the same problem with the home button delay. Is it a hardware or software problem? has anyone solved the issues?

If the fingerprint sensor works really fast, then it's a software issue

I had the same issue, even after updating to the new firmware. what i did was i restored/reset (Repaired) via the Xperia companion app. Now at least for me the fingerprint reader works flawless every single time.
So if formatting your phone is an option for you, that should work. (Was a pain re-installing all apps and re-setting all logins and all, but this really ironed out lot of issues for me)
I am on June update and I can tell you that formatting the device does NOT help. I don't have the July update yet to say if that they fixed the issue.
I hate the fact that it doesn't recognize my FP. It feels like Xperia Z5 all again. Then again FP is so deep seated and it's really difficult to use it when there's a case on.

So far my fingerprint work flawless as it should be after no reason lol.
Xperia 1 - July Firmware FPR Lag Solved/Fixed
As i mentioned before, after the july firmware my FPR works mostly every single time. I guess every phone is different or maybe you can try what i did, it may just work for you.
I did a factory reset using the "Software repair" function in the Xperia Companion with the latest firmware, now the UI is amazingly smoother and the FPR reader works flawlessly.
I have made a small video showing exactly how good the reader works now. If you have the time please watch it and also follow the steps mentioned above if you have the time to restore all the apps and setting, but trust me its better than just living with an awful finger print function.

did you already reset your phone after update?
nope cause the prob popped up couple weeks after i bought it new ....so before the update was out
To me alone with touching it is already unblocked

I'm on August update and I get this frequently. There is a bug somewhere on this and when I hit the fingerprint issue, I just restart the phone and its perfect again (well after initial pin login due to reboot haha)
It's quite annoying but haven't had time to figure it out. Something with music app running while locked or?

[FIX] Fingerprint Unlock in all Custom Roms

Just like everyone else, I, myself had a very terrible problem about custom roms unable to unlock my phone despite successful registration of my fingerprint under settings.
Here's how I was able to resolved it and this is tried and tested to be working in RR and Mokee rom.
See pictures below. Make sure to register your finger in different positions.
1. Default - thumb pointing upward.
2. Thumb facing the left side.
3. Thumb facing the right side.
4. Thumb facing downward. - this I wasn't able to grab picture of but I'm sure you got the idea.
Also, use the part of your thumb as circled below and make sure to use the same thumb for all registration.
Let me know if it worked for you and which rom.
Cheers!
Update: Tried this on PE and confirmed working.

Works on Mokee Rom, thank you, brilliant!

I'm glad it worked for you both. Please spare the word. There is no such thing as a non-working fingerprint scanner in customs rom. It works for all roms we just need to register our fingers the proper way.
Cheeers!

Tried registering 4 different fingers in different orientations like you suggested. Didn't work.. Might be doing something wrong. Even tried the same finger in different orientations.
Using pixel experience.

You have to do it with THE SAME finger all the time.

You have tried everything but the mentioned method.
Try registering your finger(any) facing upwards first through out the entire registration process.
Then add a new fingerprint again with the same finger used previously but this time pointing left through out the entire process.
Repeat for remaining two directions(right & downwards) for this same finger.
Enjoy.
Good luck again.

Hey guys,
The 9T pro is my first Ever fingerprint device.
So can someone explain me why there are issues with customroms and the fingerprint Scanner?
There is another variable that seems to affect this device in particular: humidity.
I've noticed that the fingerprint reader behaves differently if your finger is dry or wet.
This will sound stupid but if you want the best performance of the fingerprint reader, try doing the above method, but make sure you register once when your finger is very dry, and once when it is more wet. This will make sure your fp reader will work at its best in every scenario. This is the way I made the fingerprint reader work like this in PE+:

Yeah, sometimes i feel so. But its not actually slow, but sometimes when i touch the finger, there is no response.
