i seek your kind assistance to assist me to block an unwanted call/sms from particular no/person. i dunt want even a track of calls showing any missed call or voice-mail reply, as if the calls never been made to my cell. thks
For assistance with blocking any calls and text messages you should contact your cell phone company to see if they can do this for you or recomend the way it's to be done if you have to change settings in your phone.
Another option is to add the unwanted caller as a contact and block all calls/SMS from that contact. If you don't add them as a caller, many devices won't let you block the calls.
If you don't want them showing up in your contacts, another option is to set up a second gmail account and add them as contacts in the gmail account (not saved to prone) then under display settings, hide contacts in that gmail account!
