  1. Hi Thiruventakam, great tutorial. I used Mr. Number and liked it. However the latest update removed the option to select block “not in My contacts” which was the best option available in this App in my opinion. MI phone users don’t need any call blocking App as it comes preloaded, only users can turn it on when they need. I feel truecaller consumes lot of battery juice but Mr. Number is light App and consumes less battery.
