Pääominaisuudet
Älypuhelimien ominaisuudet:
⒈Mahdollisuus käyttää Internetiä langattomasti: Sen on siis tuettava GSM-verkkoa GPRS- tai CDMA-verkkoa, CDMA1X- tai 3G(WCDMA,CDMA-2000,TD-CDMA)-verkkoa, tai 4G-verkkoa (HSPA+,FDD-LTE, TDD-LTE).
⒉PDA:n toiminnolla: mukaan lukien PIM (henkilökohtaisten tietojen hallinta), aikataulumerkinnät, tehtävien ajoitus, multimediasovellukset ja verkkoselaus.
⒊Avoin käyttöjärjestelmä:Riippumattomaan ydinprosessoriin (CPU) ja muistiin voidaan asentaa lisää sovelluksia, joten älypuhelimien toiminnot voivat olla rajattomasti laajennuksia.
⒋Humanisoitu:koneen toimintoa voidaan laajentaa henkilökohtaisten tarpeiden mukaan.Koneen sisäänrakennettujen toimintojen reaaliaikainen laajentaminen, samoin kuin ohjelmistopäivitykset, ohjelmistojen yhteensopivuuden älykäs tunnistaminen ja ohjelmiston markkinoiden toteuttaminen.
⒌Tehokas toiminto:Sillä on vahva laajennussuorituskyky ja monet kolmannen osapuolen ohjelmistot tukevat.
6.Nopea nopeus:Puolijohdeteollisuuden kehittymisen myötä ydinprosessori (CPU) on kehittynyt nopeasti, minkä ansiosta älypuhelimet toimivat nopeammin ja nopeammin.
