Samsung, Apple, LG, have all been plagued with issues at the release of new software it's not something that is only effects new companies.
Unless the phone was made by Samsung or LG it will never get a great review. I don't trust what any reviewer says, because they are bias and blow Samsung every chance they get. If I actually listened to reviews I would have never owned half the phones I did. The honor 8 was the best example every review trashed the software, yet the forum was filling with nothing but praise from the people who got it.
