This phone is pretty much flawless, upgraded to the S10 just for the increased storage and honestly it wasn't as much of an upgrade as I thought it was. The S8 still very much holds it's own, it's a very nice phone. If you own the phone Koodo has some great plans, I was paying $55/month for 4gb data and unlimited text/calling. I'm not familiar with locked or unlocked phones, this may work on other carriers I'm not sure. 64gb of internal storage with SD card support for more. I have the original charger and can probably dig up the original box. I have searched for what these are going for right now and mine is about as cheap as you'll find unless you want a damaged one, so my price is pretty firm.
