According to some leaks and rumors, Samsung will update the Galaxy A30 for this year soon. The new model is thought to have a MediaTek Helio P65 SoC and 4GB of RAM. Its existence as the SM-A315F/DS has also been confirmed through a Bluetooth SIG certification.
A further variant of the same phone - the SM-A315G/DSL - has been approved for sale in the US by the FCC. This suggests that this Samsung Galaxy A will be launched in its jurisdiction sooon. However, this kind of leak cannot tell us much besides what kind of connectivity (4G/LTE) this device will support.
Then again, the FCC's testing also reveals that the SM-A315G/DSL will have a total display diagonal length of 160 millimeters (mm, or 6.299 inches). This, combined with its 7.2mm depth, seems to make for a relatively compact phone in 2020.
