Now that Samsung has released the One UI 7.0 update for this phone, it could start rolling out the update for the Galaxy A55 soon. The update could arrive as soon as next week, but as usual, the rollout depends on the carrier, country, and the region.

The Galaxy Quantum 5 has the same design and hardware specifications as the Galaxy A55. However, it features an additional security chip called the S2Q000. It is a Quantum Random Number Generator (QRNG) chip designed by SK Telecom and works with Samsung Knox to bring additional security to critical apps like banking.
