The device was spotted over on the Estonian site forte.delfi.ee and if they're correct then there's a 4.3-inch screen with a nice 720p resolution, a dual-core processor, 2GB of RAM, 16GB of internal storage and a 4-megapixel UltraPixel camera.
Obviously this is all speculation on our part because we're not sure how accurate the 'leak' is, but it looks as though it could be legitimate and Forte believe the device will be available in August for around the €400 mark! That price will probably be a fair bit more than Samsung's upcoming S4 Mini will cost, but we'll have to wait and see!
