apple doesnt want us to able to disable the message, it acts as a reminder it has been tampered with. I have fixed MANY iphones and of course once in a while while moving the home button from one screen to another it wont always survive, so it must be replaced with a fully funcioning one which is usually better than the original without of course the touch-id funtion, and even though we are fully aware, the phone will always display the message if the synced original home button isnt attached. many people have came to get other repairs and asked me this same question, but no, there is NOTHING we can do, only apple can disable the hidden setting, yes, you heard me, its a hidden setting, so just jailbreak your phone and you’ll be fine, stuff apple.
