Firmware Version 13.20.10.152 bugs

I am facing this issue right from the stock firmware. Even while the camera sound is checked off, the sound is still produced. Many users have reported this issue earlier and I had also made a post earlier where the moderator had reported this issue. Despite this, the bug has made its way to the new firmware.

Also, the PixelMaster camera app doesn't Autofocus while shooting videos which is a bummer considering that the video quality is great. This issue doesn't persist when other camera apps are used. However, PixelMaster is great, so I want to use only the default app. However, it should be able to autofocus during videos.
Another user had highlighted this issue on a previous firmware, however, it still exists: https://www.asus.com/zentalk/in/thread-117300-1-1.html
Both these issues were present from the stock firmware and were reported earlier, however they've still made their way to the new firmware.
