Stream delay on the Ps4 with YouTube without a pc or laptop?

A question I'm always live on Youtube with my Ps4 but my message always comes late you can somehow set it to go a little faster on your mobile phone, if so it would be really helpful…

There's not much that can be done about delay on the Ps4, or the mobile phone itself. Most of the time, the delay depends on how good your Wi-Fi is. But everyone has a few seconds of delay and that is completely normal. But if, in your opinion, it is too long a delay (1 minute or so) then I would think about a Wi-Fi upgrade.
