For iPhone, just slide the device to left, you will see Delete button. For Android, press and hold the icon for a while to delete it.

Hi!
I've tried swiping left and pressing the red Delete button on the Kasa iOS app, but the device just pops up again after restarting it. Is there a way to fix this?
I'm trying to delete a disabled smart plug which I had factory-reset manually by holding the settings button on the plug for 10 seconds.
I also have another plug that I'm trying to use with Alexa, but it says that I have multiple devices with the same name.

I have a hs103 smart plug. I wish I knew about sliding left.  I deleted the device and know it stops when I try to readd the device.@Kevin SG
