Overview
What this part is
Inside the Galaxy A37, a slim flex cable with contact switches runs behind the power and volume keys and connects them to the main board. If the phone has been dropped on its edge, got wet or had the buttons pressed very hard, the switches or the cable can fail.
This part replaces that internal cable. It is the right fix when the keys move normally but the phone does not react, or when the phone acts as if a key is held down.

Professional installation
How a technician fits this part

FAQ
Frequently asked questions
Will this fit my Galaxy A37?
Yes, if Settings › About phone shows SM-A376B.
Does it fit the Galaxy A36 or A57?
No. Those models use their own side key flex cables.
Can a software problem look like a broken button?
Yes, sometimes. Restart the phone and check for updates first. If the key still does nothing, or works only now and then, the flex cable is the likely cause.
Is it made by Samsung?
No. It is a brand new, OEM-quality flex cable made to fit the Galaxy A37, and it is tested before dispatch.
Should I fit it myself?
We recommend professional installation. The phone must be opened with heat, and the battery must be disconnected before any other connector.
How quickly will it arrive?
