Well, let’s go back to 2017, when Samsung relaunched the Note brand after Note 7 battery issues, with Galaxy Note FE (Fan edition).
Samsung Galaxy Note FE in a Nutshell
Samsung joined together the Note FE using unopened Note 7 units and spare parts from the original production. The result was a Note 7 FE with a slightly smaller and less volatile battery.
The phone got the Oreo update last year and maybe Samsung is generous now that its rolling out the Pie update today.
The Pie firmware has version N935FXXU4CSC4. You get all the usual Android Pie system-level tweaks, plus Samsung’s One UI interface with a dark UI mode, bottom-focused buttons, and gesture navigation. The OTA is rolling out in the middle east currently and would hit other parts of the world very soon
