If you have Amethyst on your phone you have to uninstall it first and then install garnet.
I can install only the stagenet .apk data ( https://github.com/retrnull/garnet/releases/download/v0.3.0/app-stagenet-fdroid-universal-release.apk ). The mainnet ( https://github.com/retrnull/garnet/releases/download/v0.3.0/app-mainnet-fdroid-universal-release.apk ) seems not to work with me. I am getting installing failures (invalid error)

Thanks! I would come to the idea.
It worked!!
Now, let's see if #monero works with zapping!
Anyone want to give a try?
