    I cannot stream media when the screen is turned off

    You might experience that streaming media no longer works when the screen of your Xperia™ device is turned off. The message Check your network connection may also appear when you activate the screen. One of the reasons that the network connection has been lost and streaming has been stopped may be that STAMINA mode has been activated automatically to save battery power.

    To solve the problem, try these actions one after the other. Verify after each action whether the problem was solved before trying the next one.

    • Try deactivating STAMINA mode, either manually or by connecting a charger to your device. If this solves the problem, STAMINA mode has most likely caused streaming to stop.
    • To avoid the issue, remove the streaming app from the list of battery-optimised apps. When the app has been removed from the list, you can continue streaming.
    • If deactivating STAMINA mode doesn't solve the problem, go to http://support.sonymobile.com/global-en/, select your Xperia™ device model, and enter My Wi-Fi connection keeps dropping in the search field. The troubleshooting article “My Wi-Fi connection keeps dropping” will suggest a number of Wi-Fi® related solutions.
    • If the Wi-Fi related solutions don't work, enter There is no network coverage or mobile data connection in the search field. The troubleshooting article “There is no network coverage or mobile data connection” will suggest a number of connectivity related solutions.
    • If you still experience problems with streaming, enter An app isn’t working in the search field to get a list of solutions from the troubleshooting article “An app isn’t working”.
