= Data Transfer =
Although I also have a data package in my contract, but I need these rare because I often have Wifi available where I need Internet. Honestly, even if I could not look up or receive mails while hiking in the city strolling Wikipedia, if it were me completely snuff and if it burns family or colleagues to call anyway. Nevertheless, 3G & 4G function (LTE) wonderful in large cities; at home I have no 4G reception.
= Multimedia =
MP3 player is good S4 Mini outstanding; in my plugged a 64GB Sandisk SDXC with 3414 songs incl. Covers / ID3 tags and GMMP shows / sorts the albums very fluid. For videos is 4.3 "of course bit small, even on 5.9" HTC or 10 "iPad makes me watch movies little fun, most in the train / plane maybe. The same is true for e-books reading and surfing long webpages. But help apps like Feedly Read the news. Youtube videos playing S4 mini liquid from, 720p and 1080p, even if these resolutions for 4 "Displays total overkill are saying nonsense.
= Tap =
You can not write novels on smartphones but Tap goes very smoothly on S4 mini, because Samsung's own keyboard like Swype working (off by default) and learn quickly with little training and the weirdest words. On edge-Tap is strangely convenient, because otherwise the keyboard the whole display is. It recognizes words from full English, Spanish, etc. even if you set keyboard to us, and vice versa. But that is with my HTC exactly, and probably owes more Android.
= Navi / GPS =
Since I also have a navigation system in your car or while hiking with compass'm traveling, I use Navi to S4 mini not often, but when I get lost in the city, this helps me also. Warning: If you install any offline navigation apps and only used Google Maps needs a data plan. ADDENDUM: In the meantime I use my GPS for hiking record. Despite my extremely aggressive battery saving apps GPS is not turned off and stores all cheerfully about 3-4 hours. Battery goes with me 10%! down!
= = Games
Not my competence or interest area. I do not gamble on cell phone, no Angry Birds or Temple Run ... Well, I rarely play Love & Hate. For real gamble there the PC, PS, Wii, etc.
