HI friends, Best phone I have ever had.I just got a S6 flat and you can expand the memory with a SD Memory card that plugs into the charging port, just a little info but the S6 is the best smartphone that I have ever had.
Its nice future:
1) 5.5inch alpha design but thinner bezel and more premium built & material(78%> screen body ratio)
2) sd810 / exynos both LTE cat6
3) water & dust resistance
4) Improved finger print sensor
5) 4g RAM!
6) 4k capable & OIS
it is nice cell phone and great cell phone, but not as much as great as note4.
except camera. Just one word beast among Mobile phones after Samsung S7.the samsung s 6 is Every thing is very good including build quality, battery timing is surprisingly good, only draw back is low volume of speakers.its good cell phone.
