Before you order, check that your phone is a Sony Xperia 5. This adhesive is made to hold the back housing cover in place on that model.
How to tell this is the right adhesive for your Xperia 5
Look at the model name printed on your phone or in its settings. If it reads Xperia 5, this strip set matches your back cover. The adhesive sits between the back housing and the frame, so the cover stays flush and sealed once it is pressed down.
The pack contains 10 pieces of back housing cover adhesive. Each piece is a replacement for the old strip that has worn out or lost its grip. Use the pack to replace the full set around the edge of the back cover.
Some pieces may be needed for a lifted or loose back cover. Keep the strips in their packaging until you are ready to fit them, so the adhesive stays clean and sticky.
The strips come in one pack of 10, so you have spares if one tears when you peel it off.
