The iPro Lens System range, a set of interchangable lenses -- Macro, Wide Angle, Super Wide, Fisheye, and Telephoto -- has now been expanded to include the iPhone 5, 5S, and 4/4S, as well as Samsung Galaxy S4, and current iPad models.

Schneider Optics says that a new clip fits the latest models of the iPad Mini, Air and iPad 2, allowing you to fix the lens on the back without damaging your tablet.

Prices for the kit range from $50 upwards.

For some, the advance and rising complexity of mobile devices are little more than an irritation, especially if such a gadget is only wanted in order to take phonecalls and send text messages.

If someone in your family has these needs, perhaps the Yezz Andy AZ4.5 is worth a try.

Powered by a dual-core 1.2GHz processor and running on a tailored version of Android, the smartphone features large icons and a voice assistant. In addition, the smartphone has an SOS button located at the back of the handset for emergency use -- and can be changed within the phone's settings to call an emergency contact or send out text messages if pressed.

Available at the end of March worldwide, the phone will retail for roughly $250.
