Huawei’s comparative screen-to-ratio data
Huawei has always designed its smartphones to have a better screen-to-body ratio.
Huawei has done a good job of making a 6.1” comfortable to hold and use.
This kind of design is unavoidable if screens are to grow larger, so expect others to use that same metric going forward.
Huawei has also built in some software features like a one-handed small keyboard etc, but I think that the industrial design is the best way to address this. If you are REALLY bent on using a phone with one hand, just get a small phone.
