Overview
The R380s places a mechanical numeric-keypad flip over its touchscreen, then turns into a landscape organizer when opened. EPOC32, e-mail, calendar, handwriting and PC synchronization mark an important step toward smartphone-style use.
Period and variants
The original announcement is dated 18 March 1999; its supply forecast is not an actual first-sale date. This archive places the R380s in its 2000 production period, keeping its GSM 900 / 1800 radio separate from WORLD and R380e variants.
Ericsson’s 2001 technical paper explains the passive mechanical keypad flip. Closing disables touch input; opening rotates the same screen. The phone-side processor runs OSE and the ARM organizer runs EPOC32. Their cooperation is not a modern dual-core CPU specification.
This is a closed application platform, so later S60 or UIQ application compatibility must not be assumed. Collection and retrospective descriptions disagree about memory size and purpose; RAM, ROM and user storage remain unspecified. The rear-cover battery is removable; capacity is left open pending stronger retail documentation.
