The camera is excellent among all phones available except i-phone x. Both are good.
The sound quality is better than all the market phones. You can try youtube with Samsung Note 8, S9, Huawei mate 10 pro, etc.
I highly recommended it if you use i-phone for ling time want to try others.
Good water proof. The speed is fastest among all phones available.
A little bit heavy. The most important thing is its back is smooth. It is easy to fall down. i-phone better in respect.
it is expensive, it costs HK dollar 6858.
it is the best picture capture phone available up to date. Only i-phone x can compare with it. All Samsung, LG, Nokia, Huawei cannot fight with it.
