Samsung may be gearing up to replace the Galaxy A30 with a 2020 model. It has sent this device (the SM-A315F/DS) to the Bluetooth SIG, which confirms its expected product name and its Bluetooth 5.0 spec. Therefore, this phone, much like its A41 sibling, may be a real-world device soon.
The A31 has managed to remain relatively elusive in terms of pre-launch leaks. However, it may have been spotted on the Geekbench 5 benchmarking website, as the SM-A315F. Should these results really pertain to the upcoming 2020 Galaxy A variant, it will have 4GB of RAM and run Android 10 (presumably skinned with One UI 2).
Oddly, all 4 new listings associated with the "samsung SM-A315F" indicate that it, like candidate A41s found on the same database, will have a MediaTek (MT6768V/CA) processor. Its specs and identifiers may reveal that it is the Helio P65 on this occasion.
We may have to wait until these phones are revealed in order to figure out why Samsung may have eschewed Qualcomm silicon, not to mention its very own Exynos chips, in their production. On that note, the A31 has reportedly been approved by Indian authorities to work in that country, suggesting that it may be launched in this market soon.
