Fingerprint hardware not available

[adamlee2014]

Just turned on my screen to unlock the phone with my thumb when I got this message at the bottom of screen saying "fingerprint hardware not available" so I turned the screen off and back on and it worked, does anyone know what could cause this?

this might be a bug on the software, try to observe if this occurs again. or run Xperia Diagnostics on settings.

observe your phone while on safe mode

if this keeps on, you can perform software repair using Xperia Companion

tips:

1.) you can register one finger multiple time to increase success rate

2.) always clean both sensor and finger

Hi @92, I'm sorry to hear this.

If you could take a bug report the next time this happens I can forward it for investigation.

To do this:

1. Go to Settings > About phone > Build number, tap 7 times on the build number.
2. Go back and select Developer options then turn on "USB debugging".
3. Select Logger buffer size and change it to "4 M"
4. Restart your phone, then wait for this to happen again
5. Go back to Settings > Developer options, select "Take bug report".

When the report is ready you will receive a notification. Tap the notification to share it. I suggest you upload it to Google Drive and then choose to share a public link to the upload and include the link in the PM.

Hi Christofer

A question i have. How come there is such quick response to this thread yet no Sony support staff are giving any updates on the double tap to wake issue logged even though it now spans over 9 pages and we have provided multiple bug reports.

We have had no confirmation this is being looked into further, or even had it confirmed if hardware or software issue, despite a number of us asking for an update?

I hope you can understand my frustration with this and others frustration with being ignored!

Grateful if you could chase this thread up and at least provide update what is happening?

Thanks

Ant

I have sent you the bug report in a PM

[Christofer]

@92 Thank you! I've forwarded it internally.

@AntCW I understand your concern. My colleague Rickard has forwarded that internally and we are looking in to it. I'm afraid I don't have any news though but as soon as there are any news we will let you know in that topic. I will let your post remain in this topic but please try to avoid going off topic in the future. Feel free to send me a PM if you have any further questions.

Much appreciated Christopher ☺️

Yes, I can confirm that I'm also getting the same message on my F8332. In it very intermittent and not repeatable. It appears as if when the phone wakes up from sleep, the finterprint sensor takes longer to wake up than the rest of the phone. Locking the phone immediately and waking it up again seems to make it work properly.

I have been using this phone from November 1 and so far I have seen this message twice.

Hi to everyone.

 I just wanted to mention that I too have seen this anomaly perhaps twice or thrice in about a month of usage. Also did a factory reset just in case.

Have you heard Anything back from the bug report I sent you Christopher
