If you open the Sound Settings of your Android Phone you’ll see that there are no options to change the volume settings for the Alarms. There are options to choose/change the Alarm tone while in the Alarm settings but there is no visible option to change the volume there as well. So, how to change the volume? Simple.. go to the Alarm that you want to change the volume for and open the screen to choose the Alarm ringtone and then use the Volume Up/Down keys of the phone.
