|
* Tapjacking protection in SuperSU prevents some dialogs from receiving user

* input when overlays are present. For security reasons this notification is
|
||
|
|
* only sent to apps that have previously been granted root access, so even if
|

|
|
* your app does not <em>require</em> root, you still need to <em>request</em>
|

|
|
* it, and the user must grant it.
