Infinix Smart 7 Rear Back Body Casing Housing Replacement, Verified Fit - Black

About this product

This is a replacement rear back body casing for the Infinix Smart 7, covering the battery door, side button housing, and the full plastic rear shell that ships with this 2023 release. Infinix built the Smart 7 with a plastic back and frame, at 163.8 x 75.5 x 8.5mm and 184g, so this replacement panel is molded to match that exact footprint rather than a generic stretch-fit shell. It's meant for phones where the original back door is cracked, badly scratched, has lost its finish, or needs replacing after a battery swap that required prying the old cover off. The cutouts line up with the 13MP rear camera module and the layout Infinix used across the Peacock Blue, Polar Black, Emerald Green, and Amazon Blue color variants, though this listing is the Black finish specifically.

• Matches the Smart 7's 163.8 x 75.5 x 8.5mm chassis and 184g weight distribution
• Precut opening for the 13MP rear camera, positioned per the original module placement
• Integrated side button strip for the volume rocker and power key
• Built to the same plastic back-and-frame material Infinix used on the original unit
• Micro-USB charging port cutout at the base, matching the Smart 7's 10W charging port
• Black finish, one of the closest matches to the Polar Black retail variant

How it fits your Infinix Smart 7

Because the Smart 7 measures 163.8 x 75.5 x 8.5mm, the housing's edges are shaped to seat flush against the mid-frame without adding noticeable bulk to a phone that already weighs 184g. The rear camera cutout is positioned for the single 13MP lens, not a multi-lens array, so there's no guessing about alignment or extra unused cutouts on the shell. The base cutout is sized for the micro-USB port the Smart 7 uses for its 10W wired charging, and since this device has no wireless charging, there's no coil cavity to route around, keeping the internal fit closer to factory tolerances. Side button housings are molded into the casing itself, so the volume and power buttons click through the cover rather than needing separate over-mold buttons. The 6.6-inch IPS LCD display sits on the front half of the phone and isn't touched by this rear housing at all — this cover addresses only the back and sides.

What you should know

This casing is verified for the Infinix Smart 7 only — it is not interchangeable with other Infinix Smart-series phones or Infinix Hot-series models, which use different dimensions and camera layouts even when they look similar in photos. This is a structural replacement part, not a protective case: it restores the phone's original back panel and button housing, but it does not add drop cushioning, raised camera lips, or any impact-absorbing layer beyond what the stock plastic back-and-frame design already provided. Fitting a new back door typically means opening the phone, so if the battery is being replaced at the same time, we'd recommend a professional handle that step, since prying near the battery compartment on a 5000mAh cell needs care, and any disassembly can affect the manufacturer's original warranty status if the device is still covered. Handle the plastic shell gently during installation — the clips along the frame edge are meant to snap once, and repeated flexing can weaken the fit over time.
