Global handset shipments declined by more than -2% annually in Q4 2019. Just two of the top five vendors showed positive annual growth in the final quarter of the year. Developed markets, including North America, are seeing lengthening replacement cycles. These mature and saturated markets where handset penetration nears 100% and in some cases exceeds that have little room left for new growth in handset shipments. This report details quarterly handset marketshare for the world's top 30 vendors in North America, Central & Latin America, Western Europe, Central & Eastern Europe, Africa Middle East and Asia Pacific for Q4 2019. Historical data by region and quarter from 2004 to Q4 2019 are included.
