How to remove the plus app platform on the dot brain

Click the plus sign to enter, and then click directly on the useless tab to drag and drop it.

The next time you log in, you can choose to change it.

Solved, I'm also on this issue.

Hello dear Samsung users:

Based on your description, it is recommended that you:

1.Pull down the top curtain menu of the phone - turn off the multi-window switch (go to the phone settings - display - multi-window to remove the checkbox).

2.If it is a third-party multi-window application like this machine, you can uninstall the mobile phone management software such as Phone Manager and Security Guard installed on the phone.

3.Back up your phone's data (**book, SMS, multi** files, etc.), and restore factory settings (go to phone settings - reset - factory reset).

If the problem persists, it is recommended to send the phone to the nearest Samsung service center for testing and further processing.

It is recommended that you apply for "appointment to store" on Samsung's official website to enjoy priority repair services

After the appointment is successful, please bring your machine, invoice and warranty card to the service center where you made the appointment on time.

If it's a cellphone, I keep pressing it and release it.

I started like you, I can't delete it. And then found a way.

1. Open the locked ** you want to delete.

There are two buttons to the left of shift plus backspace, the first is a minus sign and the second is a plus sign.

The easiest way, without key combinations, has plus and minus signs on the keyboard's keypad (the rightmost number area), just press it. If it's a laptop, use the key combination.

Numeric keys, there's a plus sign on the keyboard, and there's a + that's it.

Hold down shift, then press "=".

If that doesn't work, turn on the on-screen keyboard.

Colleague hold down the shift and plus keys.
