Do you have a band setup or or solo setup with instruments, and what samsung handset do you have,so that I can perhaps help you a bit more,did some sound engineering for a few bands
cool,If you have a little bit of cash ,you might want to go the the pawn shops or gumtree and get a second hand video camera with a mic input,or better,combined with a mixer as to tweak the settings of each instrument and voice and to get a mic with each instrument,then you can balance the final mic ,voice vs instruments. Some mixers have the ability to give each guy a monitor to hear themselves or a headphone input for each member,its better to hear yourself. Mixers has a solo button to isolate each member so you can set base treble ,mid and an reverb effect. if you stick with the phone option to keep it simple,you might wanna get a tripod at the chinese shop or a photography shop to get a better stable video and less noise on the audio and a room that is more or less sound proof preferably with no outside interference.The S20 is a fabulous device ,good video stability and stereo mics,try to set it up in stereo on the tripod,in a landscape orientation. Haha and keep the social distancing or at least have you and your band members checked out for corona. can't sing with masks lol
