Does the Galaxy M55 support a memory card?

Yes, the device has a hybrid slot that supports microSDXC memory cards up to 1TB, but it shares the space with the second SIM card.

How fast is the Galaxy M55 charging?

The M55 supports up to 45W fast charging, which is unusually fast for a mid-range Samsung, charging the battery from 0-70% in about 30 minutes.

Is the phone waterproof?

No, the Galaxy M55 does not have an official IP rating for water and dust resistance. We recommend avoiding contact with liquids.

What is the screen quality like?

The device features an excellent 6.7-inch Super AMOLED+ display with a 120Hz refresh rate, offering vibrant colours and smooth motion.

Is the M55 suitable for gaming?

The Snapdragon 7 Gen 1 processor can handle most games at medium or high settings, but may get warm during prolonged gaming sessions.

What is the selfie camera quality like?

The M55 has one of the best selfie cameras in its price class – the 50MP sensor allows for very detailed photos and 4K video recording.
