Android Question OnTouch events slower on new machine?

[Mansie]

My simple B4A sketch program runs smoothly on my old 7" samsung tablet (Android 4.2.2), but loading the same app into a recently purchased 7" Samsung tablet running Android 5.1.1 the drawing operation is jerky - I can no longer draw smooth curves which now appear as a sequence of straight lines.

I'm using a the reflection library with a Panel as a target - SetOnTouchListener to draw lines as I move my finger on the panel.

It seems I'm not getting events quickly enough to draw smooth lines.

Thanks as always for all responses!

Should be smooth. Are you testing it in release mode?

 

[Mansie]

yes - the identical code runs much quicker on my older machine....

Are you able to take a couple of videos of both?

What are the two tablets? Is one high end and the other not?
