Address:

The android device which i am using is poco f1.
There is bad speakers sound quality when streaming amazon prime video even after bringing the volume upto maximum extent. The video in prime video is not fit to the whole screen as youtube and its weird to watch any movie in that app while in other mind devices are awesome with the video quality and sound quality of speakers even. We are unable to take screenshots while streaming it (primevideo). And not even screen recorder is working. I compared with note 5 and note 6 and pro. They are able take screenshots and even can use the screen recorder. But is not working with the poco f1.
