According to The Wall Street Journal, Apple is testing prototype iPhones with screens as large as six inch, however they are not expected to be released this year. Apple is routinely testing prototype devices and these models might never be released, but it is nice to hear that Apple is interested in testing these devices, meaning that a larger screen might be released in the future.

The electronics giant has begun evaluating a plan to offer iPhones with screens ranging from 4.8 inches to as high as six inches, people familiar with the matter say. That would be a sizable leap from the 4-inch screen of the iPhone 5 released last year, and, at the upper end, would be one of the largest on the market.

But people familiar with the company’s internal deliberations and plans indicate it appears more willing to move ahead than in years past. Component suppliers say Apple already began testing larger screens for iPhones in recent months. Apple has been particularly interested in recent tests for a 4.8-inch screen, these people say.
