So my problem is I know android pie been around for a few months, my phone was imported to my country from the u.s with the carrier at&t and well now i have my own carrier from my country and i know pie is out here because in my country i see it and well samsung tweeted out that it came a few months ago.
My question is it possible to manually install the update? Like download the firmware and install it myself instead of checking the software update since its a no go.
If the phone was manufactured in USA and you are currently living in Brasil, then going back to the country of the manufacturer and updating it, should push through the latest update.
In the same way as with USA, an unlocked phone manufactured in Brasil may not receive further updates in the USA, due to the different manufacturer pieces the phone is made of and different software versions released.
