The Question: What do I need?
Making calls is as good as the Galaxy S3 my wife, neither better nor worse.
Internet, here it is in about the same speed as the S3.
Display, in my opinion is good, but in direct comparison with the s3 notice the difference from one to galaxy s3 sv 800x480 1280x720 pixels.
But as bad as some make the display, it is not really. The 4.3-inch display protected by Corning Gorilla SLC Glass 2 does a good job.
Processing of mobile very good.
Battery than enough for me 2 days.
Performance is very good, the system is largely liquid. This speaks for a good adaptation of the dual-core SoC with 1GB RAM.
On the whole, the HTC One SV is a round thing.
