Recently many Vivo users have encountered the crash problems when they try to mirror their Vivo phones, through some tests we found reasons lie in some inner configurations. Here we focus on the two connection situations(via USB or WiFi) to provide practical solutions for your reference：
Once the mobile phone is connected to PC via USB, a USB mode-choosing icon will pop up, then hit the “Charge Only” button.
On your phone open the “Settings”, then go to “More settings”>“Permissions management”>“Floating window management”>“ApowerMirror”, then enable the floating window of ApowerMirror.
Head for “Settings”>“Apps and notifications”>“App management”>“Special access permission”> “Ignore battery optimization”.
Notice: During gameplay process Vivo users may find the WiFi signal is limited or disabled, that’s why the sluggish performance or not very legible screen graphics may plague you. Given the above reason the USB connection is more recommend.
