Hi, I don't know, I'm bit new to this API. I think that's the PreviewSize as per the Device – user1624508 May 27 '17 at 05:28

Please take a look at the official sample apps from Google, such as Camera2Basic, or the new CameraView library. They handle aspect ratio issues such as what you're seeing.

Yes, CameraView is working well. I have been testing CameraView on Android 4.4, Android 5.1 and Android 7.0. – Alexander Lubyagin Nov 16 '17 at 18:33

Actually, the aspect ratio [bug](https://github.com/googlesamples/android-Camera2Basic/issues/69) in Camera2Basic [was fixed](https://github.com/googlesamples/android-Camera2Basic/pull/83) after this answer was posted. – Alex Cohn Dec 06 '17 at 15:23
