Hi Guys, It relates to 8 inch 16GB SAMSUNG GALAXY TAB A (Model is SM-T350) with Android 6.0.1 version. I would like to take voice recording by my speech. The quality of sound should be very good and at the same time, the recorded speech speed should be slow or medium or fast by adjusting the app. Is there any preinstalled app available on the Tab? If not, what is the best free best app for the model mentioned above?
