What Launcher are you using:
Whatever the default fora iOS is
How do you trust it
I have no choice but to trust it, once I made the decision/tradeoff to use iOS trusting Apple apps in became ‘priced in’.
On Android, I’d stick to whatever the default launcher is with the custom ROM I chose. In my experience their are many options for custom launchers and custom sms clients but almnost none that are actively developed and consistently updated.
