As you didn't mention what model Samsung phone you have there's no way to give any kind of definitive answer but if you have a model with a user-removable battery, just remove the back cover, pull out the battery, wait a several seconds, then re-assemble your phone and start it up. If your phone does not have a user-removable battery the back cover is probably more cumbersome to remove anyway, so try holding down the Power button for at least ten seconds or so. That should force your phone to power itself off.
