No point to upgrade from s6/edge to s7 as it much same frame but s7 is 20 extra grams and it not big change or anything as it wee improvement just minor I don't see any difference, I won't buy s7 as I'm wait for s8 or s9 to see if there any big improvement. I'm much happy with my s6 edge that just has been updated to 6.0.1 marshmallow look nice features. Save yer money for next one. I use san disk WiFi connect USB stick for save files that easy transfer from phone or tablet that same as SD card. If you lose phone that SD card inside you lose photo, etc.
