Let's say you have an iPhone, such as an inexpensive iPhone SE, but no iPad.
There will be times when the print is just too small, but there is an easy fix.
Using an Android app, the iPhone can be mirrored to any other tablet, such as a Nook or Kindle tablet.
Then, making sure that both devices are on the same network, start up the app and then activate iPhone mirroring From the main navigation screen. Simple.
