An equally important question: is the Samsung warranty (or the amazon warranty) valid in Pakistan? I'm afraid that only Amazon can answer that question.
Also, it's worth a phone call to the cell phone company you want to use in Pakistan if they can guarantee it works for accessing Internet. They might know that better than Amazon.
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
