Samsung Galaxy S4 Mini

Internally, it features a dual-core 1.7 GHz Snapdragon 400 processor with 1.5 GB of RAM, 8 GB of internal storage that can be expanded using a MicroSD card, and a 4.27 inch qHD (540 x 960 pixel) Super AMOLED screen.

[8] The S4 Mini received the Android 4.4.2 "KitKat" update in June 2014 (though not in all regions), bringing some minor UI changes as seen on the Galaxy S4 and S4 Active.

[9] However, Three Ireland stated later on the very same day that the S4 Mini would indeed get the Lollipop update and that it would start rolling out in the coming weeks.

[11][12] The Galaxy S4 Mini ultimately did not receive an official Lollipop update in any region.

It features a new 1.2 GHz Quad core processor, an Adreno 306 GPU, and comes with Android 4.4.4 KitKat.
