unlockFocus cannot be called if you didn't take a photo. So I think the scenario is wrong. Can you double-check the scenario, please?

@anamauad

• what is your compileSdkVersion in your build.gradle
• what is your targetSdkVersion in your build.gradle

[anamauad]

I've updated the scenario.

• compileSdkVersion 29
• minSdkVersion 23
• targetSdkVersion 29

* what is your compileSdkVersion in your build.gradle

* what is your targetSdkVersion in your  build.gradle

It is crashing also on the following devices:

Brand	Model	OS	Notes
Samsung	Galaxy A10, A21s, J4, J6, S9	Android 10	20 times in the last 7 days
Samsung	Galaxy A10, S8, S8+	Android 9	10 times in the last 7 days
Motorola	E6 plus, Z Play	Android 9	2 times in the last 7 days

In response to your question "unlockFocus cannot be called if you didn't take a photo.", it crashes the app right after pressing the shutter button.

This should be fixed with the reworked version #150
