How to stop camera flash when triggering autofocus?

In my camera app, I'm triggering an autofocus when the user taps the screen, using this code:

mCamera.autoFocus(null);

I'm also allowing the user to set the camera flash mode in an options screen. The problem is that when triggering an autofocus the camera flash sometimes triggers on some phones, and users are complaining about this. On most of these phones, this can be avoided by setting the flash mode to Parameters.FLASH_MODE_OFF. I have verified this on a Galaxy S2, but on some phones (e.g. Nexus 4) it still happens even then (according to user reports).

How can I reliably prevent the camera flash light turning on when triggering an auto-focus? Is it possible?

How did you solve this issue? – Arun Badole Mar 17 '17 at 10:11
Is this issue fixed? – Pandiri Deepak Mar 28 '17 at 13:20
@PandiriDeepak No I never managed to find a solution for all devices – samgak Mar 28 '17 at 21:16
@samgak : How you fixed then? This is really a big headache :( – Pandiri Deepak Mar 30 '17 at 10:22
@PandiriDeepak I didn't fix it. The behaviour seems to be part of the camera driver on some phones and you can't change it, as far as I know. If I knew the solution I would self-answer. – samgak Mar 30 '17 at 10:26
