I'm building application to develop vibration in Nokia 6600.And i've also read the "Known_Issues_In_The_Nokia_6600_v1_7_en" where the specify that if the device has support of MIDP 2.0 then j2me's vibration APIs are preferable instead of Nokia UI API.
But this doesn't vibrate while using the API "display.vibrate(duration);"
( where display is the object of Display and duration is some predefined value.)even it supports MIDP 2.0.(Which works fine in other series 60 devices.)
Should i use Nokia UI API instead of j2me's standard vibration API.or Is there any other option available.
