Is there any adb shell command to focus camera?

Question

I would like to record some movie on my desk but camera doesn't focus so I would like to force my phone to camera focus. Is it possible?

Answer 1

if you know the exact position to touch for focusing the camera, you can use adb shell input tap <x><y> . This will simulate a touch on the particular (x,y) cordinates.

Answer 2

i would recommend you to download some camera manipulation app like Vintage Camera by Fine Droid Devs

though it would have been better if you had mentioned your device.

Answer 3

Before you take a video, focus the camera first.

I had a similar issue with a digital camera (Canon S95). Sometimes, I'd get a blurry video. It turns out that I forgot to focus the camera first, before pressing the record button. The concept would be the same with a phone camera.
