I want to report to you a problem encountered when using Xperia 1. When using the mobile phone to play a mkv format video with the album player, it is very very stuck, and the third party player can play smoothly, but the video quality does not have a built-in player. I hope that you can make your phone's own video player better support the playback of multiple formats of video. After all, this is a mobile phone that focuses on audio and video entertainment.
