When my screen goes to stand by my phone turn wi fi off. How can i fix this if there is a solution? Thank you in advance. Lumia 520 WP 8.1 DP with latest updates. I have this problem since the April 14th.
Strange , wifi is always turned on and there isn't any way to turn wifi off when the screen times out. Try a soft reset by holding volume down + lock button at the same time until your phone vibrates and reboot itself.
