Hello developers/ modders,
i have a request for a mod/setting option on this great device. i had a wreck and cant use my hands to well...it is very difficult for me to silence an incoming call (when the phone is 'locked') as i cannot hit the small button on the top edge of the phone.
would it be possible for someone to program a 'button' or slider on the locked screen that would give me the ability to silence/ignore/decline an incoming call?
please advise.
thnx
