You might think that deleting your call history will prevent others to see the calls that you made or received but the fact is not as you imaged. Anyone who knows how to tinker with a mobile device is able to expose those calls that you want to keep in secret that you don't want others to read. This sounds scary but this is not a joke. Deleting the call history by clicking the Delete command simply takes information behind a closed door and that door can be forced to open by someone skilled in picking locks or strong enough to break the barrier.
If you seek 100% assurance that your secret calls or messages will be kept that way for posterity, you have to destroy them permanently in a more technical way by formatting the existing digits with random data, which can be done by certain data erasing software. So even the FBI agents can't figure out a way to get them back.
As far as I know, Android Data Eraser is the best candidate I have tried in last few days, it's a personal assistant program designed to permanently delete files that you do not want others to see, including call history, contacts, text messages and photos. Once you have erased your file using this software, no one could reopen it even by the most sophisticated data recovery software. The software uses a private method that the US military utilize to keep information that is classified as top secret from being seen by unauthorized persons. It works just like a shredder for paper documents but instead, this one works with soft copies.
