Is everyone with this phone happy? And how easy to unlock and root? Thanks
I certainly am. My priorities have always been:
1) Raw processor speed;
2) No acidic AMOLED craziness (S4 Mini has a setting to switch the palette to more attractive TFT LCD-like)
3) Battery life
It excels in everything: the Snapdragon 400 is a 600 with 2 less cores (and a simpler GPU), but I don't need them that badly - PPSSPP runs super-smooth, check the PPSSPP youtube videos for S4 - the Mini has the same performance; being generally disgusted by eye-hurting AMOLED colors made for space aliens - I like the screen with TFT-like setting very much: my favorite old games look the same as they were on any PC monitors of old, but with perfectly dark black color; the battery should come as no surprise to anyone that got used to, say, owning a phone with 1500 MAh and is now evaluating the added 400 = the effect is exactly that he would expect of 1900 MAh (especially after following 1-2 tutorials on reducing the stand-by battery drain, which is the fault of TouchWIZ).
With said subjective bonuses you're getting a perfectly modern piece of gadgetry that still has some S4's selling points like the infra-red thingy, Smart Stay and S-voice, dialing the contact when you move your phone up to your head, plus the wonders of generic Android 4.2.2 and LTE / NFC if you choose the i9195 model.
Oh, and the screen glass (which in itself is a true Gorilla Glass) has oleophobic coating. I, for one, will never use any touchscreen smartphone without one - it is amazingly good. And the screen reacts to the touch almost as fast as an iPhone, if not exactly as fast (this may be the Samsung's feature, I am not sure since this is my first device of the brand).
Bottom line - it is a joy to use as a mobile phone, and it has raw power for years to come, but I wish it had sliding-out gamepad like my previous phone
Oh, and today you can root any model without any problem - see this forum:
