Replacing my mini s3, this phone is simply magnificent! The screen quality is superb, the battery takes 2 days (7 hours of use for the morning until 21h in the evening I still had 70% battery), it goes fast, unlocking by fingerprint works really is not a gadget. The screen size is satisfactory, neither too large nor too small. When looking on the net, we find that the mini s5 can restart it so often been a week since I was and he never told me anything. For s3 as this was the common failure, my s3 do I ever did.
In short for those who want to have a very good phone I recommend it is perfect :)
