Keep in mind that this is the first android 9 port for it so expect some bugs here and there. This build is only for test purpose only and not meant to be used as a daily driver.
Here is what is working – boot, wifi, camera (via footej app) and SD card.

This is brought to you by Potato Open Sauce Project which is similar to AOSP firmware and that means you get vanilla android experience with no Samsung’s TouchWiz installed anywhere. The experience is quite similar to one found on Pixel series android phones. Potato Open Sauce Project team members have hand picked the best features and installed them into this Galaxy Note 3 ROM.
There are no bugs reported so far but as pointed out earlier, this is the first ROM for the Android phone so expect bugs.
