Hola!! Mod doe here and I use to draw on my phone! Although I didn’t use a stylus to draw with my phone back then I did recently have to research stylus pens for my computer and I’ll try my very best to recall what I’ve learned to help you! First thing is finding out if your phone is compatible with an Active or Passive stylus or both and knowing the difference so you don’t confuse one for the other and end up with a stylus you can’t use!
