Hello everyone! So last week I cannot use my desktop monitor as my second screen. Then I remembered Samsung Tablet S7 FE can be use as second screen to your laptop (with the Second Screen feature). I did use it one time only. The day after my first use, I decided to download Second Screen app from the playstore (this is to remove the black margins and view my tablet in full screen), but I wasn't keen on the instructions so I deleted it. However, until now, I cannot use my Second Screen feature anymore 😞 My laptop can connect to it but my tablet is always at black screen and then it will return to home screen. What should I do?
