Second screen connects, then disconnects after a few seconds (tab s7+)

[Moslash]

Hi!

I'm trying to use my tab S7+ as a second screen, but every time I connect it to my PC it disconnects after 20-30 seconds. So I'm able to make connection between my table and my PC, but after a few seconds the connection breaks.

What I tried so far:

• used the built in win+k method
• used the Second Screen app from Samsung
• updated all my drivers including the display and the wireless adapter drivers too
• installed other wireless drivers I found on my PC
• enabled all wireless stuff in my firewall settings
• switched between wlan modes on my PC

Sorrily none of them worked.

Any idea?

I have the same issue it started two days ago.

I had this problem on my Tab S7 FE after I had downloaded a screen sharing app - it interfered with Samsung's Second Screen function.

To fix it, I deleted the app, the restarted the tablet.
Of course you may have another app causing the same issue, so check for any apps which are likely, and delete them.

You may also need to reset your network connection after (note that you will lose your network/wifi and bluetooth settings, and will need to set them up again after):
Go to Settings > General Management > Reset network Settings > Reset Settings and follow the prompts. Restart your device again afterwards.

Hopefully now your second screen will work!
