Found this link for the software, does anyone recommend following the download installation instructions?
Whilst we understand the excitement at wanting to get the latest software version, we would be very wary of using unofficial sources to carry out the update and would strongly recommend waiting for the official version when available.
Sorry what's the point of the link when OP is asking about ONE UI Android 9.0 PIE ? That guide is for Android 8.1 ?
