Z5 premium - fingerprint scanner issues

[dweaver1]

With my first fingerprint this only unlocked the phone about 25% of the time - awful... 

So I re-scanned my fingerprints & it now works about 50% of the time (not sure what has changed though...). 

Better - but still fails half the time (not exactly impressive). 

Please Sony fix this...

My experience is that it is pretty good at recognizing the finger (I have registered my Thumb twice), but occasionally bugs out and it doesnt matter how hard I wipe the sensor, the finger or which one I try.

Unless I switch the screen off and on again, it wont recognize anything.

After screen off/on it unlocks on the first time.

@Dean_Weaver I hope it will last. However, did you see my last post?

Alexdon - I did see your last post, but as Sonymobile's only response was 'to do a repair' - I thought I would have to have tried this.... 

Pretty good news - just done 100 unlocks & still at 94% - things might have changed (I hope....).

Me too @Dean_Weaver. Enjoy your device.

Just got an OTA update - now 32.0.A.6.200 - re-registered my fingerprints & got 100 successful unlocks. Hope it continues...

After its appalling & mysterious deteriorating performance last year, I disabled it.....
Just got the marshmallow upgrade, so am trying it again.
Just re-registered a couple of fingers & get 98% - great...
Hope this continues.....

After two days my sucess-rate has dropped to 78% - this is useless......

My next phone certainly won't be a Sony.

Do you notice occasionally a "Fingerprint hardware not available" message in the lock screen when turning on the display?

[dweaver1]

No, but I am fed up of seeing 'too many attempts. Try again later' when it (frequently) fails...
