Can I recording stream in android and ios on half screen?
iOS’ built-in recorder can only record full screen. You need a third-party app to do this. I found 2 lists helpful: Top 10 Free Screen Recorder for Android; Ultimate iPhone Screen Recorder. Or you can mirror you screen to computer and then use FoneLab screen recorder to record half screen of your phone on computer
Just share a tip: mirror the mobile screen to computer and then record half screen with desktop screen recorder??
