Packaging and completeness check: 7 signs of forgery

The first thing that catches your eye is the box: the original Redmi Note 9 package has holographic elements that change color when tilted, and a clear embossed logo print. Fraudsters often save on cardboard quality: if the box is soft, with blurred fonts or glue marks, this is a reason to be wary.

Note the serial number on the sticker: it must match the number in the Settings → About phone menu. On fakes, you often see typos in the model (for example, "Redmi Note 9 Pro" instead of "Redmi Note 9") or color-label mismatch. Original boxes always have a matte coating - a glossy surface indicates a copy.

• 📦 Hologram: Must display rainbow effect when turning at an angle of 45°. On fake holograms either missing, or it is a regular sticker.
• 🔍 Fonts and logo: The text "Redmi" and "Note 9" are clearly printed, without blurring.
• 🔢 Serial number: Sticker with IMEI and SN on the box should be duplicated under the battery (if the phone is collapsible) and in the settings menu.
• 🎨 Color gamut: Redmi Note 9 boxes were only available in 4 colors: white, black, green and gray. Other shades (such as gold) are a sign of counterfeiting.

Note the chamber module: the original one protrudes 1.2 mm above the body and has clear edges between the lenses; the copies have either a recessed module or the lenses are not symmetrical; also check the Type-C connector, which is often a backlash or has uneven gaps on fakes.

• 📸 Camera: The original inscription "48MP" It's in a clear font next to the main lens, and the letters are blurred or offset.
• 🔋 Charging indicator: The real Redmi Note 9 glows orange when charging and green when full.
• 🎛️ Buttons: The volume and power buttons on the original are evenly squeaky, and they often fail or press tightly on copies.

If a vendor refuses to show a phone without a cover or protective film, that's a reason to question the authenticity. The original devices don't have factory case logos!
