Oh my god I am also using the same model. Samsung has quality issues after one year itself. Either they need to provide quality or they need to take the responsibility to address this type of issues.
Any updates? If it is not yet turned on, keep connected to charger for 15 to 20 mins. Try to turn it on after that. Usually this happens when battery is depleted to extremely low level or may be failing
First perform a force restart by holding the Volume Down button and Power button simultaneously for at least 10-20 seconds until the Samsung logo appears. If this doesn't work, connect the phone to its charger for at least 30 minutes and then repeat the force restart procedure.
As per your concern, we would request you kindly visit the service centre and inspect your device with the technical team end, they will provide you with all the information in a better way after inspecting the device physically.
