How to Screen Mirror Phone to Tablet/Phone (Android/iOS) Easily. I was reading about one of the biggest flops on the funding pages, a tablet screen that purported to mirror a phone screen, giving a large sized screen to mirror a smartphone. The screen was never delivered, and several million dollars was lost. Out of curiosity, I began searching for similar products, and I found a free app that uses bluetooth to mirror the phone screen to a tablet. Screen Share is free, and easy to install. It connects your phone to your tablet via bluetooth, and mirrors whatever is on the phone. While my tablet has an LTE chip and doesn’t need WiFi, it works fine for me; although, some have complained that their setup doesn’t work. Be careful who you give your money to; I am out $219 for the VinPok Split screen external monitor for notebooks, which has never been delivered. No more funding sites for me. I want to help innovation; but, you need to get your funding elsewhere.
