Sony used to make a big deal of its "waterproof" Xperia smartphones and tablets, but in reality, they were never designed to be used while submerged in water. Now, following a preliminary settlement in a class-action lawsuit, owners whose devices suffered water damage could be due a refund.

A federal court in New York approved the lawsuit, which argues that Sony deceptively advertised its Xperia products as "waterproof" when they were, in fact, closer to "water-resistant." 24 Xperia devices released between 2013 and 2015 are covered, including the Z1 and Z3, which, according to their ads at the time, could both be used underwater.

The class action seeks a 50 percent refund of a device's recommended retail price if a customer had to file water damage claims, or a 12-month warranty extension for devices still currently in warranty (six months for those out of warranty).

The Verge notes that "this may not be the final value the company is liable to refund." Sony will need to agree on final terms and settle with the court again on December 1.

The suit, which only applies to customers in the US, also asks Sony to change its packing, labeling, and advertising.
