For the past couple months, every several days my phone will alert me that there is a system update. I click "install now," and it tells me the phone will reboot in 10 seconds. It never does. When I go into my "about phone" section on my phone, it says my system is currently up to date. I don't understand why it keeps telling me there is an update or, if there is, why it won't install. Does anyone have any answers as to what's going on?
