Android automatically clears entries in your call log after 30 days. While this might be fine in most cases, sometimes you need to find a number that called you more than a month ago. Or perhaps you want to keep detailed records for business purposes, and 30 days just isn’t long enough.
Developer Robert Pérez created an app that will preserve your Android’s call history indefinitely. Unlike other similar mods that require root, this app needs no special permissions and even saves your SMS history. So if you like to keep detailed records, this one’s for you.
