Samsung saw fit to call its latest clamshell foldable the Galaxy Z Flip3, despite the fact its immediate predecessor was not so much a second generation as a 5G version of the inaugural model. Despite this slight impression of having been something of an afterthought, it seems the Z Flip 5G will not be left behind in terms of software support.
Its maker has now expanded the roll-out of One UI 4 for this foldable smartphone to the US market, whereas it had only been available for a couple of countries such as South Korea prior to this. The new firmware is reportedly available in 2 specific flavors: F707U1UEU2EUL9, for unlocked units, or F707USQS2EUL9 for those locked to a carrier.
Therefore, the 2 (which should not be used interchangeably) will upgrade the phone to Android 12, although there is a sting in this tail: the security patch level has been left at December 2021.
It might be found on the Software Update page of the clamshell's Settings in the US from now. Therefore, its users might be able to keep its hardware - which includes a display that is not all that much of a downgrade in terms of size or resolution from that of the newer Z Flip3 - going for that much longer.
