Can I update without a Windows PC and can I update without wiping my phone?
Yes as long as you rename the (.bin file to update.zip) and move it to your SD card so you can manually flash it to your phone...
Your data will stay intact, you will not lose any pics or videos, but some apps will get disabled as they are not compatible with PIE 9 See this link on how to updagrade!! --> https://eu.community.samsung.com/t5/Galaxy-Note9/Note-9-One-UI-Pie-Release-Coming-Real-Soon/m-p/8613...
Hi thanks for this - question do i need a physical SD card or can i update by saving to internal storage?!
You need an physical SD card you can NOT update via internal storage!
Where did you hear/see that Samsung are still saying by the end of the month
Launch your Samsung members app, it's in the notification sections direct from Samsung the info for ONE UI PIE 9!
