I did a try but when I touch to focus the preview is flashing. I dit it by trigger focus and reapply current ISO and speed at onCaptureCompleted. What wrong with it? Thanks

Why are you reapplying ISO and exposure time? If you're staying with auto-exposure, it'll keep working automatically during and after the AF trigger.

So generally, just set CONTROL_AF_TRIGGER to START for a single capture request (not a repeating request!), keeping your other preview parameters the same.
