Excuse me, how can Samsung i9260 set the flashing lights of unread messages and missed calls?

First, if you are referring to the LED indicator reminder function, this phone does not support the above functions.

2. "Blinking notification" means that the camera light blinks when the mobile phone receives the notification. To turn this feature on, follow these steps:

1. Under the standby page, click Application.

2. Click Settings.

3. Click on My Device.

4. Slide the phone screen up and select the auxiliary function.

5. Check the flashing notice.

After the above operation, when your mobile phone has an incoming call, the flash on the back of the machine will flash.
