At least in two cases, we may need to record the incoming/outgoing calls on a mobile phone automatically: 1) take evidence; 2) reserve for memo (to memorize the important or meaningful content inside, such as phone number, street address, some sweet memories or tender words from your lover). However, even the latest version of Android OS does not provide such a practical built-in function (I guess that may be for security and privacy concerns). Fortunately, there are many 3rd-party such applications, and callX is one of the best that AppNee wants to share with you (Automatic Call Recorder is another one).
callX is an automatic incoming & outgoing (i.e.: both-side voice) calls recorder for Android devices, developed by Smsrobot from Ireland. It comes with beautiful and modern UI design, and offers many features such as: simply shake your device during the call to start recording instantly; listen to the recorded call at any time in high-quality MP3 or WAV audio format; sync the recorded calls with the linked Dropbox account automatically, etc.
Overall, callX works as intended in a comparatively ideal way. Of course, for some smartphone models (the author only tested callX on some popular ones) and Android OS versions, therefore, you may get an unsatisfactory result of the call recordings. For example: imbalanced voice quality and volume; just recorded your own voice; the caller's voice is too loud and sounds harsh and/or clipped, and so on. Eventually, whether it can work well on your Android phone or not, you have to test it by yourself.
