Just clarifying, "touch" as in the physical feel of the phone? The glass? If so, I disagree. I don't think any part of the s7 edge feels cheap or bad. Quite the opposite. Everything feels high end to me.
HTC 10 feels high end, too.
I may have a preference for glass phones, but nothing about the s7 edge feels cheap.
My native language isn't english, and I don't live in english speaking area, so if I'm describing something wrong, my apologies
By 'touch' I mean when u physically touch a screen. Sometimes Samsung phones register a touch even before u actually touch a screen, so called 'ghost touch'. And even when that doesn't happen, surfing thru lot of tables inside apps (gplay for example, but can be in any app), TW simply doesn't handle things smoothly like some other android devices out there. Touch simply isn't accurate like on Nexus, OnePlus X/Two, Xiaomi mi5, etc.
I'm comparing this only to the phones I've actually owned.
I hope this was well explained, doubt I can do better then this
