Prevent harassment settings We usually say the ad phone, or some harassing phone, specifically we prevent harassing phone as an example.
1. Enter "Application" under Samsung A3 interface.
2. Click "Set".
3. Here we click on the "Call/information blocking" option, open into the details below.
4. Click "Call Stop" first, because we want to open it, the default is off.
5. Click "Block registered number only" as shown below.
6. Click on "Call Block List".
Click the "+" icon.
8. Then we will not want to answer the phone to add to the surface here, and then click "Save" can be.
Ok so I can prevent this phone number harassment, this phone call and SMS phone will not notify you and will automatically intercept, the other side also do not know that you add it to the blacklist, will only hint that your phone is in the middle of the call. In this respect I think Samsung mobile phone is still quite humane.
