The claim is strongly supported by the validated Counterpoint Research page, "China Smartphone Market in Q1 2026: Huawei Share Highest in 5 years, Apple Fastest Growing," which directly states that China’s smartphone shipments declined 4% YoY in Q1 2026, Huawei reached its highest quarterly share in China since Q4 2020, and Apple had the strongest growth among the top six brands. The searched X post at https://x.com/DeItaone/status/2045129520416473237 matches those same details, and Reuters search results for "Apple's iPhone shipments in China surge 20% in Q1, data shows" independently echo the 4% market decline and Huawei leadership. Because the primary validated source directly substantiates the statement and corroboration attempts align with it, the statement is likely true.
