Comment 1 for bug 1368702

Note that this might only be caused by a yet missing feature in unity8:

If you tap very close to the edge (in an area that can trigger an edge gesture), right now the touch is lost. However the plan is to forward that touch to the application if unity8 realizes this is only a tap (instead of an edge gesture). Once that is in place in unity, buttons close to the edge should be reachable much easier.

Would be a pity if we waste precious horizontal space in the header workarounding the issue instead of properly fixing it. I advise to reevaluate this after gesture cancellation in unity is in place.
