To turn off the drop-down screen on your device, you will need to follow the specific steps depending on the type of device and operating system you are using. However, in general, you may be able to disable the drop-down screen through the device's settings menu.
For example, on an Android device, go to the settings app and select "System," then "Gestures." From there, you can toggle off the feature called "Swipe fingerprint for notifications" or similar, which should disable the drop-down screen when you swipe down from the top of the screen.
On an iPhone, you can disable the drop-down screen by going to "Settings," then "Notifications," and selecting "None" as the notification style for each app.
In summary, disabling the drop-down screen will vary depending on the device and operating system you are currently using. But you can turn off this feature by accessing the settings menu and looking for the notifications and gestures section.
