The issue manifests primarily via third-party apps — like Snapchat, Facebook Messenger, and WhatsApp — with users of those applications experiencing low-volume, tinny, distant audio. In further experiments, it seems affected apps are exclusive...
Facebook: It remains buffering...
Instagram: A reload icon appears and nothing happens after tap on it.
YouTube: Video screen remains black and only audio works
and should restart the mobile and happens again after while
i tried every thing...
