Recently, we received an email from a Samsung Galaxy S4 user whose volume key is not working. The email reads, “Hi, I recently upgraded my Samsung Galaxy S4 to Android 4.4.2. During calls when the screen is off, the volume key does not work. Do you have any idea what wrong? Thank you.”
Possible Causes of the Problem
According to various forums and articles online many Android users have been experiencing similar problems when they upgraded to 4.4.2. It looks like it is not only an issue with Samsung devices as HTC One, and Nexus 4, 5 and 7 have also been complaining the same trouble.
How to Fix the Volume Key Problem in Galaxy S4
If update is the one to blame, call your carrier about it, so they can come up with another update that contains a fix. After that, simply install the fix if it rolls out. Another alternative would be to root your device and install an custom firmware. Just make sure that it corresponds to the brand and model of your device.
A recommended tool for rooting is Odin. Ensure that you have the latest version running. Then, one good source of firmware for your device is from SamMobile.
Be reminded though that rooting, especially if not done properly, has the tendency to cause more problems to your device. The damage can go as far as bricking it or rendering it completely nonfunctional. So, do your research first about the process before going through it or seek help from someone familiar with it.
