Who is world no 1 phone?

If you mean the world’s No. 1 phone brand overall, there isn’t one single answer that stays true at all times. Samsung and Apple are usually the top two, and they often trade places depending on the quarter and the metric (shipments, market share, or sales).

If you mean the best-selling individual phone model, it is often a current iPhone model from Apple’s latest lineup.

If you mean the best phone overall, that’s subjective and depends on what you value most, such as camera, battery, price, or software.
