A phone that may be the Samsung Galaxy M31s pops up on Geekbench
Samsung has released a successor to the Galaxy M30 already in 2020; now, it seems the M30s may get the same treatment. A device called the "samsung SM-M317F" has been tested on Geekbench 5. As the M31 is the SM-M315x, it is possible that this novel identifier corresponds to an incremental variant.
On the other hand, should this new leak prove valid, the putative M31s may not be much different from the pre-existing mid-ranger. It is listed as having 6GB of RAM and as running Android 10, which is something offered by the actual M31.
Furthermore, this "SM-M317F" apparently runs on the Exynos 9611, which is also present in the M31 and is getting on in years at this stage. Therefore, it seems that the scope for distinguishing features in this new Galaxy MXXs variant has shrunk in 2020.
