Do A51 cases fit A51 5G?

Samsung A51 Case - Encased Slim Fit Flexible Grip Cover for Galaxy A51 (Will not fit The A51 5G Version) Brief content visible, double tap to read full content.

Is the A51 and A51 5G the same size?

I believe the A51 is just barely smaller than the A51 5G. This might make a case for the regular A51 too small to get on the 5G while a 5G case on the regular A51 might leave too much play for the buttons to work correctly.

Is the Galaxy A52 the same size as the Galaxy A52 5G?

The Galaxy A52 and A52 5G share the same 6.5-inch AMOLED panel, and the A72 gets a slightly larger 6.7-inch screen. Other than the increase in size, the panel quality itself is identical.
