Help Face unlock lag?

Thanks for the reply. I don't think it has to do with recognition though, since the lag I'm experiencing has to do with the camera "getting started". Once the camera sees my face, the sped is just fine. :)

Oh I meant the fact that with increased training, when you launch face unlock/unlock the phone it takes time to load the database of faces it stored before it activates the camera.

I havent tested this theory myself yet.

I thought the same, however a few people above disproved that theory. In other news, up to 13 stars!

lol. 13 is better than one or two, but maybe people just aren't noticing the delay. As in, it got progressively slower and they never noticed it changed?:confused:
 
Yes, I'm having the same issue. Anyone figure it out? I think its just that it puts the camera out of memory and has to load it up as we install other apps, etc.
 
I'm rooted on stock 4.0.2 YAKJU

Everything is flashed from the official google build. radio and bootloader as well. Unlocked the bootloader though.
 
Ok I think I've done it but need further testing ...
Only possible on rooted devices ..
Go to folder
/data/data/com.android.faceunlock/shared_prefs/
in your root enabled file browser (I used es file explorer)
Open the file inside
Edit delay number to 1
Save file
Then change permissions to read only by all
And ownership to root
Go 1 level up and do the same with the shared_prefs folder (perm and owner)
And again 1 up and same settings to the com.android.faceunlock

Come back here and report if it improved


Not sure if all the permissions must be like that but I went safe on it since file got replaced first few times I tried
Please do.come back here to report if it worked for you too

My delay was 1730 after changing to 1 it worked like charm once but then it changed to ~700(file got updated again) then I've changed the settings of files and folders to present override and now I did not experience the lag yet :D


Let me know if you need more info or more detailed instructions 0,O
 
Also I feel I should mention ive done it on moto g 1st gen
And that minimum time for it to open is same as time it takes to swap from back to front camera in your stock camera app plus time it takes to detect light conditions and in dark places it takes longer to do that :)
