    ok bro!! ngoja nisubiri.ila wakati nasubiri ningependa kujua kwanini chines 4nes zinazidi kupunguziwa vifaa ndani.mfano.zamani C.P.U,RAM,SIGNAL PROSESSOR,CHARGING IC, E.TC,vitu hivi vilikuwa vinajitegemea ila jinsi siku zinavyoenda ndivyo vifaa hivi vinazidi kufungwa sehemu moja ambayo ni NDANI YA C.P.U hivyo kulazimu hata kama ulikuwa na tatizo la kuchaji basi inakubidi ubadirishe C.P.U. kaka hauoni jinsi gani inamlazimu mtu kuingia cost ile ile bila kujali tatizo la simu yake,BILA SHAKA UMENIELEWA NINACHO MAANISHA MKUU.
