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!

I had the same issue and I had this issue for a long time. Sometimes it works fine, but when you need it the most it won't work. I don't why sometimes and feel Samsung doesn't do enough testing and QA for their new software features which is so good for some users and others don't use it that much. As long as they don't receive enough a lot of complaints the will not act.

I have the same problem on tab s9. Just moved to spacedesk. It free and works. How bad is samsung for this problem to be going on for years and over several generations of tabs

I have the same problem. My Tab S9 was working perfectly at first and I was delighted to be able to use it as an extension travel monitor. Then, after two months of working perfectly as a second screen, it started disconnecting after 20 seconds. Extremely disappointing performance for what, for me, was a major recommendation for the Tab S9.

I was having issues like this, then I found out I'm connected to VPN. Beware of that.
