Why can't glory do vivo?

The reasons why glory can't do vivo are as follows.

1, glory ranked third with 15% share, OPPO ranked second with 2 1% share, and vivo continued to lead the domestic first with 23% share.

2. After glory left Huawei, there was a gap in the middle. Glory has not released new products for a long time, resulting in the loss of many users, relying only on the old models to maintain the existing market at that time.
