Samsung s3 mini. Screen is black but the buttons light up, phone vibrates and makes notification sounds. No cracks on screen. It flashes a strip of color down the side when turned on or off. Tried removing battery and restarting already
When did you get your phone? Was it working properly?
I would go to the nearest Koodo shop and ask them if you can send it for warranty repair. If it doesn't cover by warranty, they will tell you the cost of repair. You can go with it or you can bring it to local repair shop.
