Galaxy M21

Galaxy M21 — what matters when choosing accessories

The Galaxy M21 measures 159 × 75.1 × 8.9 mm and weighs about 188 g — still a comfortable body considering its 6000 mAh battery. The Super AMOLED display has a 6.4-inch diagonal and a resolution of 1080 × 2340 pixels, and the 20 MP front camera sits in a U-shaped notch. The front is protected by Gorilla Glass 3, while the back and frame are made of plastic. On the back there are three cameras: a 48 MP main camera, an 8 MP ultra-wide and a 5 MP depth sensor.

Galaxy M21 cases — types and uses

A plastic back will not shatter like glass, but it quickly picks up scratches and fingerprints. The cases in this category cover different needs:

• Rugged and reinforced cases — thicker corners absorb the energy of a drop, and a raised lip protects the screen and camera.
• Clear cases — thin, they show off the colour of the phone and protect it from scratches.
• Silicone and carbon-pattern cases — they sit securely in the hand and add little noticeable thickness to the phone.
• Decorative cases — hard cases with glitter or prints from fashion brands such as Guess and Karl Lagerfeld.
• Original Samsung cases — clear covers with a factory fit.

Tempered glass and screen film for the Galaxy M21

The AMOLED display with its camera notch is covered entirely by the protector — the notch lies beneath the glass, so the protector needs no cut-out. You can choose full-screen tempered glass with a black frame, thinner and flexible hybrid glass, or antimicrobial films. Separate camera protectors will guard the protruding lenses.

Galaxy M21, M21s and other variants

The Galaxy M21s and a later edition of the M21 are also on the market — these are separate variants, so check the model designation in the name of each product. Some cases are described by their manufacturers as compatible with both the M21 and the M30s; in that case both models are listed in the product name.

How to choose accessories for the Samsung Galaxy M21

• For everyday carrying in a pocket, a thin case and hybrid glass are enough.
• For outdoor work or when there are kids around, a rugged case with tempered glass is the better choice.
• The phone charges at 15 W — you will find cables in the USB-A to USB-C cables category.

Accessories for related models are in the Galaxy M22, Galaxy M23 and Galaxy M30s categories, and the whole family in the Galaxy M20 Series section.

Frequently asked questions

Does a Galaxy M21 case fit the Galaxy M22?

You should not assume so — the models differ in dimensions and camera layout. Choose cases with M21 in the name, or ones for which the manufacturer explicitly states compatibility with several models.
