Try our beta app from https://play.google.com/apps/testing/com.record.my.call

RMC - Record My Call has a basic purpose to record all your call (incoming and outgoing). Please be noticed that due to limitation of Android phone (hardware and software), this program only can record from microphone. Please turn on the loudspeaker during conversation to get clear voice from the other side. All conversations are recorded under file “RecordMyCall” file in memory card. Please use speaker to get a better record quality during call.
