I used the Samsung Galaxy 10 Tab 3 to setup Chromecast and started the Netflix movie on my TV. After about 2 - 3 minutes the Galaxy went in sleep mode. At the end of the movie I tried to stop it but Samsung didn't find the Chromecast device. I cannot see it on Samsung until I turned Chromecast's power OFF/ON and restarted it. On Netflix screen I still can see that I started movie only 3 minutes ago even if really I casted it all on my TV using Chromecast device.
Any idea how can I solve this problem to keep my Samsung still connected to Chromecast even in sleep mode?
