It is assumed that we are talking about the second generation of Pocophone smartphones (sold under the Poco brand in India). No other useful information is indicated in the trademark application.
A well-known insider, Sudhanshu Ambhor, had doubts about the veracity of the leak: the Pocophone F1 was not sold in China, but the Poco F2 brand was registered in the Chinese center. However, _The_tech_guy recalled that the Pocophone F1 was also registered with the China Trademark Office.
