Dear friend you dont need tap each phone individually. You can buy rig for phones with psu. You connect them usb. At same it charges and shows all phones in 1 screen. It means you can tap all phones at same time. Watch on youtube cryptoleo.
I dont need it but I ordered auto clicker device which can click 9 phones at the same time on aliexpress. It is good for iphones.
There are several auto clicker apps for Android. No need any auto clicker device.
Thanks for the tip. it is a good device. 20 phones conenction. I hope I can find and order that device.
