wifi issue (Samsung s6)

[ado84]

Hi folks.

I have a Samsung s6. Spotify premium user.

Everytime I use an app which involves wifi usage....mobdro....youtube...showbox etc my wifi is perfect.

Once I open spotify it causes my phone to disconnect from wifi and then it won't reconnect for about 30 sec and so on.

Sometimes it even causes my phone to no longer recognise my wifi and therefor have to reboot the router.

As I said this ONLY happens when I use spotify.

I have smart switch turned off on my s6 and I have also changed the channels on my router and still no improvement.

Can anyone please help as it is very very fustrating.

Thank you.
