What You’re Getting
This is the exact gold fingerprint sensor flex cable designed specifically for your Samsung Galaxy J4 (2018) SM-J400F/DS or J400G/DS model. It’s the piece that connects your fingerprint reader to the phone’s main board – when that connection goes bad, your biometric security stops working entirely.
Why This Part Works
We’ve tested this replacement to match the electrical specifications and physical dimensions of your Galaxy J4. Hundreds of repair shops across South Africa choose our components when they need reliable parts that fit right the first time. The gold contacts maintain solid connectivity, so your fingerprint sensor should respond just like it did when your phone was new.
Installation Notes
Before you start: plug in the new cable without fully installing it to check if the fingerprint sensor lights up. Use an anti-static wrist strap if you have one – those tiny circuits don’t like sudden zaps. When connecting the cable, avoid sharp bends; keep curves gentle rather than folding at hard angles.
Warranty & Support
This flex cable comes with six months of coverage – if anything goes wrong during that time, we’ll sort it out. Your order ships free anywhere in South Africa, no delivery charges added. Need help? Message support@phoneparts.co.za or WhatsApp 063 193 2306. Over six hundred repair technicians regularly use our phone parts for their daily fix-it jobs.
