This replacement brings that crisp button action back to life. Hundreds of local repair technicians choose this part for their S21 fixes because it just works.
Installation Notes
Before you start, give the new cable a quick test if you can—just connect it and tap to see if it registers. When you’re working inside your phone, an anti-static wrist strap is a smart move to protect the delicate bits. Be gentle with the ribbon; don’t fold it sharply or bend it too far. Delivery to your door is free anywhere in South Africa.
