The One Plus is jumping on the bezel-less bandwagon, as this what the market wants. Ironically it wasn't the big players who started the trend; it was the Xiaomi MI MIX that started the whole thing almost six months before Samsung was ready to ship its bezel-less Galaxy S8.
Apple wants to go bezel-less too and nearly bezel-less with the overpriced and ridiculous iPhone X, and so now everyone else in the industry wants to go down that path. This is the trend for the future, and remember there are companies developing fingerprint readers under the screen, but this technology will be ready during 2018 and not for Autumn refresh phones, including the OnePlus 5T.
One Plus 5 did a great job with a dual camera, Snapdragon 835 with 6GB RAM + 64GB Storage for $479/€499 and Snapdragon 835 8GB RAM + 128GB Storage for $539/€559. The 5T is likely to get a 16:9 screen to match the bezel-less concept.
People forget that the One Plus has excellent audio support including Bluetooth 5.0 and aptX & aptX HD. Many believe that ApteX HD is the future and will play sound better over a wireless connection. The 5T will continue this tradition.
There is one leaked render of the phone, and we expect to see an announcement soon.
