Apple has captured the market of elite. However, in the middle and lower class markets Huawei (Chinese phone company) is giving tough time to apple. Can Huawei outclass iPhone? Huawei has already introduced the slimmest smartphone and the first water and dust proof smartphone of the world.
I personally think that there will still be a portion of consumers loyal to Apple because they are used to their software (iOS) and would rather stick to it than changing to other OS. However, whether Huawei outclass iPhone would really depends on the future release of iPhone by Apple and the time taken. It's not something that would happen instantly. P.S: Slimmest smartphone, Water & Dust proof smartphone is indeed very appealing.
