Motorola One Action

The Motorola smartphone can still record widescreen videos even when positioned vertically.

For the selfies, the A51 comes with a 32 MP sensor, while One Action comes with up to 12 MP images with the front camera.

Performance and storage

Both models feature a processor manufactured by Samsung. The A51 has an eight-core chip that reaches up to 2.3 GHz speed. The successor to the A50 still has a larger RAM, with 6 GB. The Motorola cell phone has the Exynos 9609, which has eight cores up to 2.2 GHz and 4 GB RAM.
