The other day my phone popped up with a message which said security update failed
it started flashing and turned off. at first it kept freezing, and now it will turn off and to turn it back on i have to plug it into a charger and it says the battery is flat... even if i have just charged my phone, it can happen straight away. if i dont use the phone it is fine, but as soon as i start using it, it turns off.
