You get many repeatedly unmotivated phone calls from numbers unknowns?
Follow the guide to download and install my application, I solved some problems with callcenters who kept calling me at all hours, now I'm the one calling to block their phone lines automatically from my phone.
Installation is very simple, it does not require the phone root or any other setting.
After downloading your Callbomb apk file to your phone, go to your files folder on your phone and go to the download section where you will find the apk file you just downloaded.
