You can remote unlock the phone via android manager online, this is a great way to access and unlock a device when you either have an issue like this or forget your password/ pin

Thanks for the reply, but actually the problem is not unlocking the phone, because i remember the pin, the main problem is why my Zenfone 3 seems like not detect my fingerprint scanner, you can see the screenshot, there should be a fingerprint menu, but now its gone. how is that possible and how do i fix it? its so annoying because fingerprint is the major feature which makes it a bit expensive.

I seriously don't know. If i were in that situation. I would backup all my data first. Then reset the phone to factory state. If it happens again. I would contact Asus. Or check their forums for a solution.

okay, maybe contact asus is the best solution, because i did factory reset and even hard reset but nothing works. Thanks for trying to help by the way

You use ZenUI Launcher ?
My Phone locked with ZenUI launcher (double-tap on screen) => can unlock with fingerprint.
When I use Nova Launcher => Lock phone (by double-tap on screen) => can not unlock with fingerprint!

For some reason i can use nova launcher prime and still able to use the fingerprint scanner. I even went as far as unintalled the Zen UI launcher.

Probably due to root access, mine is unrooted so fingerprint won't work with Nova. Installing dan configuring Screen Lock Pro will fix this, but have to wait 10 seconds after screen off to allow fingerprint unlock. Not so convinient.

Exactly, the convenience it brings is really great. Especially if you have a 25 character password lol. My password's too long for me to enter it all the time. And yes, maybe because of root access i'm able to do that

It is how Android 6 behaves when a third party app locks screen.

Have you ran Asus hardware test?
If not - have a try:
- open phone calculator (stock Asus) and type .12345+=
Pls note - no zero before the dot
- in the pop-up app, select single test, then fingerprint test.
If the test result is ok, your issue is software only. In contrary, it's a hardware failure.

Great tip.

I ran the test, fingerprint test went wrong.
So, in my case, it`s a hardware failure.

Just make sure it isn't hardware failure by running above mentioned hardware test. If the test suggests there is nothing wrong with hardware, then switch to swipe as unlock method first before setting up and returning to fingerprint unlock from scratch.

Mine is having problem like this.
Hardware test says it is working well but when I tried to register print no response at all.
Tried the pattern lock method as well but no luck.

Same case

It's happened to me also. I have done the test (.12345+= in calculator) and it said "something wrong with fingerprint test". For this case i'll contact Asus. It's really weird why so many people having same problem like this. Actually my device has been used for only no more than 3 months. I'm afraid there will be new other problem in the future.
