in fact the use I see no advantage in Galaxy S6 compared to Nexus 5. While the processor is much more powerful, but as I had no problem of slowness I see no benefit.
One big drawback, however. I have many applications and I used to sort by alphabetic order but Samsung just forgot this feature, so I had to install a launcher in place of TouchWizz.
The headsets come with the phone are in "Apple" but the listening quelite is really zero (as often provided for oreilletes with Samrtphone but for having a galaxy S3 atria were so much better). Fortunately the format is standard I donate my old ears could récpérer (Seinnheiser, tr_s good audio quality).
A plus for the rapid charger delivered avce smartphone .... which is really fast!
Nice tool but I do not feel any real difference from a 5 nexus that has 1 and a half and listen 40% cheaper (in 32GB).
Connoisseurs using the camera or greedy performance will certianement very satisfied.
