Can this also be done via Bluetooth or cable?
For example, I would also have a USB OTG cable for Android and one for the IPad.
and can you mirror the 2 devices on a laptop? And maybe even control the laptop from your mobile phone?
To the best of my knowledge, this is usually always done via Bluetooth. At least I think I know that it used to be. 🙈
And how and with which apps?
