It’s probably happened to most people – for some reason you have a friend, colleague, or an ex decide that it’s time to blow your phone up with neverending calls, texts, MMSes, and calls from everyone’s phone they can get their hand on at the bar telling you to come out at 2:17 a.m. on a Tuesday. Call Master can help with that for rooted devices.
While you can directly block people from most Android devices now, preventing your phone from ringing on unknown, withheld, or private numbers isn’t something most carriers ship options for.
Call Master can prevent people from blowing up your phone with their Gatekeeper feature which will put someone in timeout during which you’re not bothered by them for calling too many times within a specified duration, or at 2:17 a.m. on a Tuesday.
Should you feel like it, you can also route someone’s text messages to another number based on custom filters. I’m not quite sure what use this has, but it’s there if you want it.
Call Master keeps an independant contact library, which is good for transitioning between ROMs, or perhaps hiding contact information from your Google contacts. You can also set it to auto-add phone numbers you dial so these are whitelisted to call you back.
Overall it’s a much more robust application than what it was in the early beta days when we first looked in on it back in 2011.
Call Master is free and requires root.
