China’s smartphone makers Xiaomi, Oppo, Vivo and Transsion have lowered their full-year shipment forecasts amid rising memory prices in the supply chain, according to Jiemian News. Xiaomi and Oppo have cut their projections by more than 20%, Vivo by nearly 15%, and Transsion to below 70 million units. The reductions mainly affect mid- to low-end models and overseas markets. The companies did not respond to requests for comment. A source familiar with the matter said that manufacturers often report higher order volumes to secure resources from suppliers, adding that memory makers such as Samsung and SK Hynix have not been informed of any actual shipment cuts.
