ANDROID - Nak clear catch

Senang jee...

Tapi whatsapp bikin hp aku selalu hang... banyak gambar & video... banyak yg ulang tayang :(...

Dah tak masuk tahap tak boleh "CLEAR CONVERSATION" dah... Bila cuba nak "clear"kan... lagi teruk "hang"nya :(... Jadi pilihan yg ada sekarang.... delete satu-satu... :(
