A Brazilian teenager used the Fleksy for Android to break the Guinness World Record for fastest texting, previously held by the Word Flow keyboard of Windows Phone 8.1. Marcel Fernandes Filho typed his 25-word message in 18.19 seconds on a Samsung Galaxy S4.

The record was broken on April 25 in New York City, and edged out the previous record-holder by .25 seconds. Filho was required to use perfect spelling, capitalization, and punctuation.

Fleksy is a relative newcomer in keyboards. It was in private beta for a while, releasing to the public back in December. Fleksy uses large keys and places an emphasis on prediction and auto-correction in an attempt to let users keep their eyes off of their phones while typing. Fleksy currently supports Dutch, English, French, German, Greek, Italian, Portuguese, Russian, Spanish and Turkish.

Oh, and the message that Filho had to type? "The razor-toothed piranhas of the genera Serrasalmus and Pygocentrus are the most ferocious freshwater fish in the world. In reality they seldom attack a human."
