ZenUI Dialer & Contacts is a phone app that lets you make calls and also blocks them.
ZenUI Dialer & Contacts helps you access contacts on your mobile phone and dial them faster and easier. But perhaps the function that is more important is its ability to block spam and other unwanted calls. The app has a "smart" blocking tool that allows you to block all numbers from private and unknow numbers and also designate numbers of known spammers to be blocked.
The app has a number of other functions, including the ability to use passwords to protect contacts you want to keep private. It also has a security feature that allows you to use the phone's camera to record when someone types in wrong passwords, which can help you catch someone who has stolen your phone or is trying to access it illegally.
ZenUI Dialer & Contacts is free to download and easy to use, and it is available in multiple languages, making it the perfect tool to protect your contacts and block unwanted calls.
