Leaks about the upcoming Samsung ATIV SE have been intensifying lately and now a new report claims that it will hit Verizon in April, but without Windows Phone 8.1.

The Samsung ATIV SE hasn't exactly been the best-kept secret, as it has leaked on several occasions so far. Despite the several leaks, however, there's still plenty we don't know about this purported device, but here's what we do know so far.

The handset will reportedly launch as a Verizon exclusive in the U.S. and it will be very similar to the Samsung Galaxy S4, both in terms of design and specifications. It is expected, however, to be slightly higher-end than the Galaxy S4.

The Samsung ATIV SE will reportedly sport a 5-inch, full HD display with 1080p resolution and pack a quad-core Qualcomm Snapdragon 800 processor, paired with 2GB of RAM and 16GB of internal storage capacity. It is also expected to boast a 13-megapixel rear camera and have a microSD card slot for additional memory.

Samsung's upcoming ATIV SE was also rumored to come rocking the latest version of Microsoft's mobile operating system out of the box, making its debut at the BUILD 2014 developer conference. According to new information, however, the Samsung ATIV SE may not come with Windows Phone 8.1 on board after all, but get the new OS through a subsequent upgrade.

"Samsung is preparing to release its next Windows Phone handset on Verizon next month. Sources familiar with Verizon's plans tell The Verge that the Samsung Ativ SE will be made available as a Windows Phone 8 device, despite the upcoming announcement of an 8.1 update. While images originally leaked with a promise of Windows Phone 8.1, the Ativ SE will receive the update once it's ready for the handset," The Verge reports.

Microsoft is expected to release its new Windows Phone 8.1 OS in early April during its BUILD 2014 conference, and it remains unclear why the ATIV SE will not run the new OS. Nokia is holding its own event on April 2, the first day of the BUILD conference, where it is expected to unveil its Windows Phone 8.1-powered Lumia 630 and Lumia 930. The ATIV SE was expected to be among the first smartphones to showcase the new Windows Phone 8.1 as well, alongside Nokia's upcoming Lumias.

The Verge further notes that the Samsung ATIV SE will become available on Verizon's network sometime in April, launching as "a reasonably sized alternative to the Lumia 1520, or even the Lumia Icon."
