Galaxy S4 Mini is the performance version of S4, but cheaper and smaller in size, thus becoming a smartphone as powerful as it, but more affordable. It has a screen of 10.9 cm, about 4.3 inches, and therefore it is still much bigger than the previous S3 mini version, and it will be launched sometime in June this year, without so far knowing exactly when.
This mini version will have a 8 MP rear camera and a mini dual core 1.7 Ghz processor, which might cause critics to argue that this version will not be anything but a downgrade, it remains to be seen! Anyway, it will be cheaper and more afordable for everyone.
