'New' fingerprint speed hack

Search This thread
This is new to me, turn off the battery optimized for apps: com.samsung.android.biometric



The fingerprint scan is so quick, the screen makes the change, the fingerprint animation hasn't finished. Try it!



Placebo or not???!!
I say NOT a placebo. This seems much faster.

"com.samsung.android.biometric" doesn't show up in my apps list under settings . I'm using the SM-N975F/DS, which is Exynos version. Does anyone have Exynos based Note 10 who is able to change this setting?

OK, found it under "special access" , I have to search for "Optimize battery usage" in the settings search bar and then filter for All apps, then look for "com.samsung.android.biometric" and turn off battery optimization. Tried this setting, and I only notice a very slight improvement in unlocking speed. So maybe this doesn't benefit Exynos devices as much. Would like to hear others' experiences.

Settings menu, search for optimize, select optimize battery usage, change list to all, look for com.Samsung.biometrics.app... Uncheck it.

When looking at the apps listed I see seven com.samsung. apps . I cannot expand them to see which one is for biometrics. I am missing something. Can you tell me which one it is?
Thanks

When on the full list of apps, use the search for bio; that should bring it right up.

There was speculation on the Reddit thread about this potentially burning out the scanner faster. Any logic behind that theory?

    Testing on S20 Ultra and this seems pure placebo. Toggling it off and testing and then back on and testing and like that a few times I do not see any difference in speed to unlock. Biggest difference for me has always been just how dry (or not) is your finger. If your skin is really dry, expect a lot of misses or delays. I'm using the Snapdragon variant of the phone.

    Edit: Definitely placebo. Did a blind test, where I didn't know whether the app was optimised or not and tested the sensor and many times when it was off I thought it was on and vice versa. This makes no difference.
    Maybe not for s20, but my note 10+ definitely notice the difference. Less error too.

    Testing it for the second day. We'll, the finger unlock is now usable... I'm completely surprised such a small thing can make such a great difference. So looks like when app is automatically put to sleep the delay we're seeing is because Android need to wake up the unlock process. And this is a very expensive operation that contributes to the felay. I bet a sensor burnout is a complete bs though. Also if you notice most of the critical system applications are excluded from better optimizations... But not the fingerprint unlock. What could that mean? Either it's draining the battery (did not notice the drain yet), OR some engineers in Samsung have their hands growing from a wrong place.

    Again, thanks for a great tip.

    Another trick to make it even faster!
