Truecaller: Caller ID, spam blocking & call record
Comment
Being using the free version of true caller for while now , overall I've been very impressed I've changed phone a number of times and always revert back to using true caller the functions are great . ID is always accurate and the spam setting is very useful. I've never really had any issues with the app. The way it will I'd the caller even if you do not know the number is really great and sets it apart from stock android .
