My device will not go on and does not show any sign of life even when cinnected to its charger was working ok till thus morning
graeme, check the charging port and make sure it is not bend or has any debris in it. You can clean it with a few puffs of air and some isopropyl alcohol. Make sure that you charger is working properly. Use a multimeter and see what it puts out. After that, you may have to open up your Galaxy and change the battery.
