In 2019, we saw how Samsung released several midrange series in order to stay relevant in competition with other manufacturers. The company completely revamped its lineup in terms of specs and naming. Gone are the A + one number designations, now we have A10, A20, A30, A40, A50, A60, A70, A80. There are some derivatives as well, such as Galaxy A10e or the upcoming S-upgrades.
A recent filing by Samsung Mobile for trademarks at the European Union Intellectual Property Office is revealing and tells us what to expect. The Galaxy A11, A21, A31, A41, A51, A61, A71, and A81 are the respective successors to the existing A series devices that we have come to love.
It is a simple, logical naming scheme that should work well. The next generation after these will logically be Galaxy A12, A22, A32, and so on.
