What is the difference between the A50 and A51

The A51 builds on the awesome A50, taking each aspect and making it even better. The A51 has a 6.5" infinity-O display, maximising every part of the screen while minimising the bezel. This makes it the perfect place to look through all of the incredible photos taken on one of the five cameras on the A51.


Compare the A50 and A51 in the table below.
