Factoring in the crop, smartphone camera lenses typically translate to around 28-35mm in 135 terms, which is certainly on the wider end of a normal range. Not a super-wide by any means, but also not ideal for portraits, unless you want the face to be quite small in the frame. 
(Iām only really used to shooting at 50 and 135mm, so 35mm feels uncomfortably wide to me.
