Re: why is my samsung note 8.0 only shows samsung on screen and doesn't open?
It's bricked. What caused it and what you do to fix it depends on what you did before it happened. It could need no more than a cache wipe in recovery or it could need the firmware reflashed. (Or it could be a hardware failure - defective memory can cause a device to hang during boot.) If you have an SD card in it, turn it off, remove the card and try again. A corrupted card can sometimes cause the Media Scanner to hang for hours.
