I can't answer calls on my Samsung j3!!!

Solution
Was the phone working normally beforehand? Was the phone dropped.

Could be the result of a failed update of some sort.

Do you have the User Guide/Manual?

Check the troubleshooting section.

I also did some googling and found the following link:

Google "samsung j3 black screen of death fix" for even more links.

I do not have a Samsung phone so cannot vouch that any given solution will work. Read carefully and be careful about what you try.

Otherwise contact Samsung for assistance.
