As speculated Samsung has announced S4 mini with a smaller 4.3-inch qHD Super AMOLED display (compared to Galaxy S4) powered by 1.7GHz dual-core Processor along with 1.5GB of RAM and 8GB of internal memory with microSD slot support for extending the memory up to 64GB as additional storage.
S4 mini runs on the latest version of Android Jelly Bean 4.2.2.
In terms of Camera, S4 mini comes with both primary and secondary camera with an 8-megapixel rear-facing camera and a 1.9-megapixel cam on the front face.
One of the downsides with the device is, it comes with just 1900 mAh battery compared with 2600 mAh of Galaxy S4. Even though it may not look less to many users, it is still less when it comes to have a good battery life.
