SDK 23 Touch Lag on Android Devices

#1

Another Problem I found with the latest update is that the touch sometimes registers very late.

The second time I actually tapped the Scanner immediately, but if you notice it took so much time to register my touch. But as soon as the touch is registered, the scanner opens up quickly, so its before the registering of touch thats lagging and not after the touch.

on iOS however I found the touches to be buttery smooth as compared to the previous versions.

I suspect this is related to ending/restarting the camera hardware session for the barcode scanner when you close it and open it again.

This lag, I have observed at many places, inside my app as well, when I am rendering a list. Similarly in the expo app sometimes the lag is there when I click on the “exp” ip address as well.
