I've noted that the fingerprint sensor unlock doesn't work after taking the device out of my pocket. Perhaps something with pocket mode handoff? The device doesn't register as it's in pocket mode when this occurs. Just wanted to pass this along! @Taker18

I recently bought a Zenfone 2 (ZE551ML) which works exceptionally well however today I've noticed something odd (probably would have noticed it before but the phone was actually a gift so not at all times with me).
During a call the proximity sensor will only turn off the screen when the phone is close but it will not turn the phone on when I move it away. I've gone through many online articles and in the majority of cases it was a problem with the screen protection. However, I do not use any kind of screen protection.
Additionally I've noticed something really odd. Zenfone 2 has an inbuilt testing suite (SMMI Test) which allows testing various parts of the hardware. The proximity sensor test consists of three steps (NEAR, AWAY, NEAR). They should be self-explanatory (NEAR triggers when an object is close, AWAY when its far). In my case the first step (NEAR) always triggers after the test starts but the other two (AWAY, NEAR) simply won't. That's until I use the app switch button (next to the home button) to re-enter the test application again. The other two steps then complete successfully.
Considering the behavior can I rule out a hardware problem and pin the issues to the software?
The proximity sensor issue was successfully resolved by reverting back to the 2.20.40.90 firmware. The 2.40.40.97 version (at least WW) obviously has issues with it.
You can find detailed instructions on how to perform stock recovery in this topic (http://forum.xda-developers.com/zenfone2/help/reverting-to-stock-firmware-t3225632).

Hi Everyone,
My phone model is XT1635-02, with Android 8.0.0 and build number OPN27.76-12-22.
All of a sudden the phone froze and not responding to any inputs. So, i rebooted it and i saw a fingerprint hardware not detected message on the bottom center of the screen.
From that moment the fingerprint sensor in not working and settings are not available on security & location section.
I tried all the methods i found on you tube and some forums but no luck
I even hard reset it but when it booted up as a new phone it acted like as if there is no fingerprint sensor present at all.
If you guys have any idea regarding this, please help me out.
P.S Phone is not rooted.
Thank you.
This won't help you but I have a personal rule about fingerprints on phones and laptops. I don't use them. I find them to not be dependable.
Why the pocket mode for Mi 9 SE was missing? Someone know how to turn it on? If I running or ride by bike - fingerprint display is still active.

I think the fingerprint scanner is always active when the phone detects motion. The in screen readers work differently from the others. Someone correct me if I am wrong. Does it seem to have any effect on battery life?
@cman245: I have Mi 9 SE only two days ... I don´t know any effect on battery life. But pocket mode is missing for me. Fingerprint indicator is still active by aby motions.

Mine is the same but I haven't noticed any problem. Mine rides in my pocket a lot. Only part of the screen turns on and I would think it uses a lot less power than static display like on Samsung devices. Pocket mode is definitely not there but I'm not sure that it is a problem. Is so, maybe Xiaomi will address it in a future update.
In ROM from xiaomi.eu is option to fingerprint indicator off by motion.
The easiest way to deal with that is, that the phone should be able to detect when its in pocket by using the distance-sensor that detects when you put it to your ear when telephoning.
hope they fix this soon. i have so many pictures and videos taken while in my pocket.
just get its messing up when my pocket goes really hot...
cheers andy
The easiest way is install xiaomi.eu (stable or weekly).
I have "wake on notifications" and "double tap to wake" disabled.
The phone still wakes all the time while inside my pocket.
If I'm listening to music, it causes the music to pause every few minutes and once it was even locked due to "many wrong password attempts".
Super annoying. Does this not happen on xiaomi.eu? Also, is google pay working on xiaomi.eu stable?
EDIT: I update to 10.3.1 and I think they might have fixed it. I'll see if it happens on my comute back home, as it seemed to happen most when I was listening to music/podcast and the phone received a notification while in my pocket.
I just tested, now if I block the top portion of the phone with my hand, the fingprint reader no longer responds to touch. So they've basically implemented/fixed the pocket mode.
Also, if block the top of the screen while the lockscreen is awake, is instantly turns the screen off and disables touch.
On xiaomi.eu is not this issue. I´am rideing by mtb bike with Youtube Music + TrueWireless headphones and no problem.
I've been using the latest global version for a day now. It's been fixed.
Pocket Mode is built in somehow and a half working but working.
Phone is, in generally, garbage except Samsung SAMOLED and final finishing.
THE WORST THING IS PROXIMITY SENSOR MALFUNCTIONING as at most Mi phones... GAR-BA-GE!
I am disappointed at all
There are not yet implement pocket mode to SE model.
Mi 9T and Mi 9 have the same UltraSonic proxy sensor as SE but have a Pocket Mode option in latest XEU ROM and SE don't have yet
Where is and what is the problem for implementation?
Dear Friends
A50 current version A505FDDU1ASE3 / A505FOJM1ASE2 / A505FXXU1ASE2, Security patch level 1 May 2019
The issue: very slow FP reading plus Face reading is not good, it can open the device with eye closed face, even with the diagonal angle too, which is dangerous, it means anybody can unlock your phone while you sleep.
I have logged the call with Samsung support and they advised to upgrade to the latest version through the phone, which I did. and asked to delete the registered FP and Face, and re-register it.
I did, the problem remains the same... anybody found a similar issue?
FP reader posts are dime a dozen in this forum. To provide my opinion, the FP reader was extremely poor in March, significantly improved in April and now seems to be working at the level allowed by the hardware.
It takes less than a second to completely unlock using the FP reader, but for that you have to register your FP in the various positions you would normally unlock it and then make small adjustments. Don't follow any guide telling you to register using specific movements. This is what works best for me.
The Face Unlock is extremely insecure as it unlocks with photos and closed eyes. It is there only for convenience.

I have been facing the same issue. I got my phone on my birthday in March month; I was excited about the Samsung A50 device, but when I set the screen lock using fingerprint, it gives delay. Also, I have the latest version of Android 9. Still, it troubles me.
Followed this guy for a while very interesting videos ,but one thing stick out on this one at around 10 mins on ,if you have to have a new screen fitted fingerprint stops working ,until you use fingerprint recalibrate tool which Google provides on line .Just wondering is this could be used to recalibrate finger print sensors for those having issues,tap post for video
Just to add my FP works fine so not willing to risk trying this ,but some one having issues it could be the answer

The calibration tool, by the looks of it, only tells the system that the new module is verified (by the user). This is because the phone, strictly speaking, doesn't know much about the (black box) fingerprint reader. The reader itself just sends its "signature" (most likely a serial number or something similar), how many fingerprints are registered, and the phone can request a read (which either returns recognised, not recognised, or faulty/impartial read), or a registration.
Simply said, the phone does not have access to the raw fingerprint data, for security reasons. But this can mean that if someone replaces the FP reader with one that has different fingerprints loaded, they could abuse that and unlock your phone with their own finger. By disabling the FP reader when an unknown signature is detected (i.e. you, or someone else, replaced the screen), the user is notified about the change, much like the warning screen during boot if your bootloader is unlocked.
The calibration tool, as such, is the user's way of telling the OS that yes, you've authorised this replacement. It shouldn't make the existing FP reader better or worse.
Ok wasn't sure how it worked just thought it might be worth a try for those having FP issues
As far as I know, Google already said that the calibration tool won't help you get a better result, it's just and solely for people that replace their display and want a functioning FP scanner again (without the tool the phone doesn't recognize the new FP reader of the new display).
