I got a new samsung s6 edge on 14th Sep. Long story short there was aproblem and i went to the place where i bought it and got replaced two times. But my third device had some problems too. So i contacted fido chat and the reprentative sent me a new device without providing much info.
Now I have this new device working fine and other device not working fine. Do I need to return the other device? how? Should I keep it to see how the new device is working and when I am sure I can return it?
