What does -2 means in the androidspy call logs,does androidspy call logs show blocked or private called numbers

Call your provider they can add a feature so no private calls go through without them adding a *.. Before your number to show there number.

there's a few ways.
the first way is to log online to Verizon wireless and under your profile it says "block calls and messages". you can add a number there.
or on your phone you can download an app that lets you block numbers or you can click on the number (from your phone) and depending on the phone you can click on the settings and block or auto reject the number

You would have to subscribe to that feature from your local phone company, then when a number like that calls they will get a recording that states you do not accept blocked calls...

You can't. When caller-ID shows "Private", it means that the caller does not want you to know what number they are calling from. (Tip: These are good messages to let the answering machine answer. If they want you to call back, they'll have to leave a number.)

Check your Sim in another phone to confirm , if there is no CLIP then the service provider has barred you and must get in touch. Also is possible that the phone has hung up because there are errors in the software. So to reset remove the battery and the memory card from the phone. Using your PC , scan the memory card for any corrupt files or media files with virus- it is possible when they are downloaded from unsafe sites. If so remove or format the card. Now replace the card and battery and switch on the phone. If the phone hangs up then it is confirmed that the software is corrupt and will need a reinstallation. Seeking help from the authorized service /support centre is most ideal. Take estimate and decide.

Using Call Block
If you subscribe to Caller ID, you can save phone numbers to the call block list. When a call comes in, the phone compares the received phone number to the numbers on the call block list. If the phone number is on the list, the phone replaces the caller's name with Call Blocked and disconnects the call. (The caller hears a reject tone.)

The call block list holds 20 entries, and all stations share the same list. You can add entries through the Call Blocking menu, by selecting Add Call Block in the CID menu, or by blocking incoming calls. (Only one station can edit the call block list at a time.)

Blocking incoming calls

1. When the phone rings, wait until the display shows the Caller ID information (usually after the second ring).
2. If you want to block the call and add this number to the call block list, press Block.
3. When the phone asks you to confirm, press Menu/select or Block. Blocking an incoming call from an "Unknown" or "Private" number is the same as selecting Unknown Number or Private Number from the Call Blocking menu.

Call Blocking menu options

1. With the phone in standby, open the menu and select Call Blocking.
2. Choose one of these options:

• Create New(Handset only) - Add an entry to your call block list. The phone will prompt you to enter a name & phone number.
• Private Number(Handset only) - Block all calls from numbers reported by CID as "Private." (This does not count as one of the 20 entries.)
• Unknown Number(Handset only) - Block all calls from numbers reported by CID as "Unknown". (This does not count as one of the 20 entries.)

Call block entry options

1. With the phone in standby, open the call block list and find the entry you want.
2. Press Menu/select to open the individual entry menu. Choose one of these options:

• Edit(Handset only) - Edit this entry. The phone will prompt you to edit the name & phone number.
• Delete - Erase this entry from the list & allow calls from this number.

It probably wont allow you to because of the service you have. That is probably a option for another service provider. call your cell phone provider and ask if they can block the number.

If you have a private number or unlisted number, you must dial *67 before dialing the number. This is only needed if the number you are calling rejects blocked/private numbers.

to list a contact the easy way just type the number it and press options and it will display save go from there

if some one called and u missed it when the screen shows one missed call it should show the number if not it was private u can also go in to call log and go to dialled calls.recived calls.and missed calls and will show u the numbers
