6.55″:
It is a small display format for smartphones. You shouldn’t be severely defective in vision, and you won’t see much detail on the screen and only have a small resolution available. For that, the device should be small and handy, easy to transport.

Honor:
In 2014 Huawei created the sub brand Honor and offers certain smartphone series under this name. Occasionally the products are also called Huawei Honor.
The market share of Honor products is manageable, but there are several reviews on Honor smartphones with average ratings (as of 2016).
85.25%: This is an above-average rating. Nevertheless, it should not be forgotten that about one fifth of all tested models receive a better rating.
