When i install the tiktok app my volume always lower to its default settings. I notice this when i left tiktok and browse facebook for watching videos and content. Suddenly my media volume turns down to its default setting while watching fb and also when playing games which is 70% or 80%. So i uninstall tiktok and the issue was gone. I always wanted to watch video in tiktok but with this issue i choose to uninstall it rather than to have this issue. Please fix this. I also experience it with my other galaxy device.
