The new G Pad devices will be unveiled at the MedPI 2014, which is one of the biggest tech trade shows in Europe. The show will be held from May 13-16.

Apparently, the new G Pad tablets come with proprietary UX features like QPair 2.0 and Knock Code.

According to sources, LG is also offering an updated version of QPair. The "Q-Pair 2.0" application, which connects tablets and smartphones, will allow users to receive calls and send messages through tablet PCs. They are also equipped with batteries with longer life.

The Knock Code will let users power on and unlock their LG smartphones by simply entering a personalized ‘knock’ pattern on the smartphone’s display.

Talking about the size, the LG G Pad 7.0 will be LG's smallest tablet. The 8-inch G Pad 8.0 will be a mid-sized tablet, while the LG G Pad 10.1 will have a 10.1-inch display.
