Typically, this means the flex cable on your new iPhone has been damaged, and you will have to replace the iPhone 5s power + volume button flex cable in order to get the buttons working the way they should again.
This type of damage often occurs when the device is dropped or bumped, causing the cable to become damaged in some way.
This is not an easy job for someone who has no technical skills with Disassembling or Assembling Cellphones/mobile phones, so only purchase this item if you know how to install it.
Highly recommend professional installation.
We will not be held responsible for any damages to your cellphone/mobile phone that you may cause during the changing of replacement parts
