I regularly tether / hotspot using an iphone 5 and have lightening fast download speeds (e.g. a 100 Mb file is downloaded in seconds). I recently acquired an S7 edge and the hotspot / tethering speeds are very very slow (e.g. A 10Mb file is downloaded in minutes). The former is good. The later is unacceptable. For these test cases both phones are in the same location connected to 4G.
Is this a carrier issue or a problem with Samsung hardware / Android software?
Other than ditching the S7 edge, what can I do to resolve this?

A friend of mine had a similar problem followed this advice and in the end did a factory reset and this solved the problem.
