If you would like to use icons from the Play Store without a 3rd party launcher you can use Awesome Icons. It will allow you to use any icons from any icon pack in the Play Store. It will only change your home screen icons though, it will not change the icons in the app drawer. If you want to change the icons in the app drawer you will need to use a 3rd party launcher.I saw that but that requires me to install the icon pack from the Samsung Store. She has free and paid icons from the Play Store she'd like to apply. Is that not possible without either a different launcher or the use of yet another app? Seems convoluted on a Samsung device.
Thanks for the help. That's what I'm trying to avoid doing. Hilarious how Samsung doesn't incorporate this stuff. Such a big name in the industry and you get zero freedom.
