AutoFocus is not working on Galaxy S9 and S9+ with Zxing library
・symptom
The app is using zxing 1.9 for QR code reading.
It works well in almost android devices, but dose not work well in Galaxy S9 and S9+ devices.
It seems like auto focus is not working.
Upto Galaxy version 8, no problem.
・environment
Android : 5 to 8.0
Kernel ver : 4.9.65-144892203
zxing : 1.9 version
Device : Galaxy S9 , Galaxy S9+

I solve the issue with following code.
Working well with Galaxy S8, S8+, S9, S9+.
private val autoFocusExecutor = ScheduledThreadPoolExecutor(1)
fun startCamera() {
if (camera == null) {
camera = Camera.open()
if (camera == null) {
showCameraErrorMsg()
} else {
preview.camera = camera
capturereceipt_textview_cameraerrormsg.visibility = View.GONE
capturereceipt_framelayout_viewfinder.visibility = View.VISIBLE
autoFocusExecutor.schedule(Sc{
val params: Camera.Parameters = camera!!.parameters
if (params.getSupportedFocusModes()
.contains(Camera.Parameters.FOCUS_MODE_CONTINUOUS_PICTURE)) {
//TODO: Auto focus not working
params.focusMode = Camera.Parameters.FOCUS_MODE_CONTINUOUS_PICTURE
}
camera?.parameters = params
}, 1000, TimeUnit.MILLISECONDS)
}
}}
