Unresponsive Fingerprint Sensor

[QuantumDogg]

Is it just me or is the fingerprint sensor just not very good on the Samsung Galaxy A70. To try to use it to unlock my phone is pointless, very, very rarely works, in fact, can't even remember the last time I was actually able to unlock my phone this way..... Yet, open an application that uses biometrics, not a problem with any of them.... What gives? And yes, I have more than one fingerprint registered Any constructive advise welcome.....

Hi @QuantumDogg 

A couple of tips I picked up when setting up the finger prints are.

When setting up take x3 scans with each thumb and then rotate the phone around when taking further prints of each thumb so your phone can read both thumbs from the same finger print scan. Scan your prints as you would normally hold the phone.

Also using two fingers when setting up one fingerprint works pretty well.

Go into Settings . Biometrics and Security.  Biometrics Preferences . Turn Off Screen Transition Effect.

Then go into Settings and search for Optomise Battery Usage. Tap in Optimise  Battey Usage  tap to show All and scroll down to com.samsung.android.biom and toggle Off

For me this improved the fps on my Note 10+ 5G which I appreciate is a different model to yours but should be the same outcome- hopefully.

I also have dry skin on my fingers and so find it sometimes beneficial to moisten my fingertip or breathe on my fingertip before unlocking the phone.

Hi @BandOfBrothers

Thanks for the advice.

Not sure if the Screen Transition Effect changes anything, seemed to be the same whether this was off or on but the Optimise Battery Usage tip did the trick!

Been running with that off as suggested and now have no problems unlocking my phone.

Once again, many thanks, much appreciated.

There's one good tip you can try, add the same finger a couple of times, this seems to work on most device's including the A70 that you have
