A wobbling back cover on your Galaxy A40 makes every pocket slip and every drop a worry. This adhesive pack gives you a clean way to secure it again.
What You’re Getting
You get 10 pieces of back housing cover adhesive, enough to rebuild the bond for several repairs or to keep spares on hand. Each piece is designed for the SM-A405 model, so you won’t be guessing about fit.
Compatibility
These adhesives match the Samsung Galaxy A40 with model number SM-A405. Check the model printed on your phone’s settings or box before ordering. Each item was inspected for good condition before it left our warehouse.
Installation Notes
Fresh adhesive only works if the old residue comes off completely, so clean the frame edges thoroughly first. Work in a dust-free spot and keep the phone powered off. Wear an ESD strap to protect the internal components. Avoid bending any ribbon cable past 90 degrees while you lift the housing. Professional fitting is the safest route if you feel unsure, since a misaligned cover can cause damage.
