S8 Plus airplane mode
I landed here while searching for my airplane mode problem with my S8 Plus. Apparently, people are already using this app to turn off the radio altogether and save battery at last.
I'm very eager to try this but then the app showed a warning pop up about disabling the radio phone altogether, so I'm here to confirm if it's actually safe to use on Galaxy S8 Plus. My airplane mode is draining more battery than WiFi, the same problem like all others before me.
My phone is S8 Plus on Android 8.0. They have disabled the 4636 menu, so I lost access to the radio phone.
